Guernsey–UK: residence, employment, investment income and relief

Who this applies to

The Agreement applies to residents of one or both territories. Article 3 defines geographical Guernsey as Guernsey, Alderney and Herm, with adjacent territorial sea; it does not list Sark. Do not equate the treaty definition with every place in the Bailiwick. Article 2 identifies Guernsey income tax and UK income tax, corporation tax and capital gains tax. This Guide does not establish social-security, immigration, VAT or inheritance-tax relief. Articles 1–3.

Article 4 residence requires liability by domicile, residence, management, incorporation or a similar criterion; source-only taxation does not suffice. Establish domestic residence first, using the individual Guide and appropriate UK rules. Transparent entities need Article 1(2)'s income/resident attribution test. The Protocol supplies additional Article 4 interpretation, including a specified Guernsey exempt investment-fund provision; do not infer that a zero liability alone proves either eligibility or ineligibility. Articles 1 and 4; Protocol paragraph 2.

The Agreement entered into force on 7 January 2019. Ordinary effective dates are 1 March 2019 for withholding in both territories, 1 January 2020 for Guernsey income tax, 6 April 2019 for UK income tax and 1 April 2019 for UK corporation tax. Historical transactions require the appropriate earlier agreement. HMRC currently identifies this Agreement as in force. Treaty-status page; DT8600.

Article 1(3) preserves each territory's taxation of its residents except for the expressly listed benefits in Article 7(3), Article 9(2), and Articles 18, 19, 22, 24 and 25. Apply that reservation alongside residence and allocation rules; a statement about source-territory limits is not a universal exemption from residence taxation. Article 1(3).

Residence conflicts

For an individual resident in both territories under Article 4(1), apply Article 4(2) in sequence:

1. Permanent home available; if available in both, centre of vital interests (closer personal/economic relations).
2. If that centre cannot be determined, or neither territory has an available permanent home, habitual abode.
3. Habitual abode in both or neither: competent-authority mutual agreement.

There is no nationality tie-break step in this treaty's individual rule. Retain home availability, family/economic ties and living-pattern evidence rather than treating a passport or one year's day count as decisive. Article 4(2).

For a dual-resident non-individual, Article 4(3) calls for competent-authority agreement taking account of effective management, incorporation/constitution and other factors. Without agreement, treaty benefits are unavailable except those under Articles 22, 24 and 25. Do not apply an automatic effective-management tie-break or deny every benefit indiscriminately. Article 4(3).

Business profits and permanent establishments

Article 7 generally reserves enterprise profits to its residence territory unless business is carried on through a permanent establishment (PE) in the other territory; that other territory can tax profits attributable to the PE. Establish treaty residence and entitlement before this allocation. A treaty restriction is not itself proof of a domestic exemption or a substitute for domestic filing obligations. Article 7(1).

Article 5(1) defines a PE as a fixed place of business through which the enterprise's business is wholly or partly carried on. Listed examples include management premises, branches, offices, factories, workshops and extraction sites. Assess actual premises use and activity rather than concluding from a registered address or customer location alone. Article 5(1)–(2).

Issue	Treaty rule and evidence
Building/construction/installation project	A PE under Article 5(3) only if it lasts more than twelve months. Establish commencement, completion, interruptions and project identity; do not substitute a fixed 365-day test without authority.
Limited activities	Article 5(4) lists facilities/stock solely for storage, display or delivery, stock solely for processing by another enterprise, and a place solely for purchasing or collecting information. Its other-activity limb requires preparatory/auxiliary character; combined listed activities require that character overall. Read the exact limb rather than importing a different treaty's wording.
Fragmented operations	Article 5(5) can disapply the paragraph 4 exception for complementary functions forming a cohesive business operation, where the same/closely related enterprise operates at the same or another place in the same territory and the specified PE or non-auxiliary combined-activity condition is met.
Contract-concluding agent	Article 5(7) covers a person acting for the enterprise who has and habitually exercises authority to conclude contracts on its behalf, subject to its stated exclusions. Contract practice and authority matter, not just job title.
Independent agent	Article 5(8) protects business through an independent-status broker/commission agent/other agent acting in the ordinary course of its business. Verify both independence and ordinary-course conduct.
Parent/subsidiary	Control alone does not make one company a PE of the other under Article 5(9). Other fixed-place or agency facts still need assessment.

All rules: Article 5(3)–(9). For paragraph 5, Article 5(6) defines close relationship by factual control and adds a more-than-50% direct/indirect beneficial-interest test, with the specified vote/value/equity measures for companies. Exactly 50% fails that automatic percentage limb but is not a safe harbour from factual control. Do not apply Article 5(6)'s definition as a universal threshold for Article 9 or the investment-income articles.

Attribute profit from evidence, not a fixed turnover fraction

Article 7(2) treats the PE as a separate independent enterprise in the same/similar activities and conditions, considering functions performed, assets used and risks assumed through it and the rest of the enterprise. Prepare a supported attribution calculation, including internal dealings; neither all worldwide profit nor an arbitrary share of turnover is automatically the PE base. Article 7(3) provides an appropriate corresponding tax adjustment where an attribution adjustment causes the specified double taxation, with authority consultation if needed. Article 7(2)–(3).

Other articles continue to govern separately covered income/gains under Article 7(4). For example, Article 6 permits the property territory to tax income from immovable property, including enterprise property and letting income; absence of an Article 5 PE does not by itself exempt that rent. Articles 6 and 7(4).

Ownership boundary example: assume 100 equal beneficial interests with no special rights or indirect interests. Holding 50 is 50%; holding 51 is 51%. Only the latter necessarily meets the more-than-50% numerical limb. Both still require the paragraph 5 business facts, and the first can be closely related through factual control. The arithmetic does not decide a PE.

Supplementary regression control retained byte-exact.

Attribution working-paper illustration: assume a separately supported Article 7 analysis attributes £200,000 revenue and £130,000 allowable costs to a PE. Attributed profit is £70,000. If review of an internal dealing establishes an additional £10,000 attributable profit adjustment, the revised base is £80,000. These are hypothetical evidence inputs, not a treaty-prescribed margin, cost deduction or tax rate. Apply domestic tax law and corresponding-adjustment procedures separately.

Supplementary regression control retained byte-exact.

Unresolved: detailed project aggregation/timing, remote-worker premises analysis, agency interpretation and transaction-specific attribution, including unsupported internal financing or head-office charges. The ordinary domestic base and return sequence is supplied below; the illustrations do not establish a PE or validate those fact-dependent amounts.

Employment allocation and thresholds

Ordinary employment remuneration is taxable only in the residence territory unless the employment is exercised in the other territory, in which case the latter can tax the remuneration derived from that work. Directors' fees, pensions and government service have separate Articles 15, 17 and 18, to which Article 14 is subject. Article 14(1).

For work exercised in the other territory, Article 14(2) preserves residence-only taxation only if all three conditions hold:

Condition	Evidence needed
Presence does not exceed 183 days in any twelve-month period commencing or ending in the fiscal year concerned	Travel record and rolling-window calculation; not calendar-year or workday counting alone
Employer paying, or on whose behalf pay is made, is not resident in the work territory	Employer identity, residence and employment/assignment arrangements
Remuneration is not borne by the employer's permanent establishment there	Cost allocation, recharge and permanent-establishment analysis

Source: Article 14(2). Exactly 183 satisfies the numeric limb; 184 does not. Satisfying that limb does not settle the employer or cost-bearing conditions. The detailed domestic presence-count conventions and economic-employer interpretation require verification for the actual assignment. Article 14(3) separately addresses qualifying international ship/aircraft employment.

The base and Guernsey credit ceiling

For a Guernsey resident's income that the UK can tax under the Agreement, Article 22(1)(a) provides credit for UK income tax paid, subject to Guernsey credit law. Paragraph (b) caps it at the Guernsey tax attributable to that income before the credit. Confirm identical income, periods, eligible tax and the treaty's UK taxing right; a payroll deduction is not by itself proof that all tax withheld is treaty-permitted. Article 22(1).

Where income is taxable only in the UK under the treaty, Article 22(1)(c) instead allows Guernsey to include it when calculating tax on remaining income. Article 22(4) excludes the paragraph 1 credit where UK taxation is permitted solely because the income is also derived by a UK resident. Do not turn a dual-residence fact into an automatic credit. UK-side relief follows Article 22(2) and UK law; this Guide does not compute it. Article 22(1)–(5).

Article 1(3) preserves residence-territory taxation subject to its listed exceptions, including Article 22. Article 23 can deny a benefit when obtaining it was a principal purpose, unless granting it accords with the relevant provisions' object and purpose; paragraph 2 provides a competent-authority request route. A residence certificate does not displace those rules. Articles 1(3) and 23.

Domestic treaty-credit calculation and claim clock

Income Tax Law section 173 applies where section 172 arrangements provide credit. Section 173(2) requires the person entitled to the income to be resident in Guernsey in the credit year. Under subsection (3), calculate the pre-credit Guernsey tax on total income divided by total income, and multiply that effective rate by the relevant foreign income computed under Guernsey law. This is the domestic same-income ceiling; subsection (4) also caps aggregate treaty credits at total Guernsey income tax other than tax payable as agent for a non-resident. Establish eligible foreign tax under the actual agreement before comparing it with those ceilings. A statutory election under subsection (8) disallows treaty credit for that person's income for the year. Section 173(1)–(4), (8).

Section 173(5)–(6) governs the income base: do not simply deduct foreign tax before computing credit. Apply the received-in-Guernsey gross-up and eligible underlying-distribution-tax addition where their respective conditions hold; the final proviso allows a deduction for foreign tax exceeding the credit. Reconcile that deduction with the applicable income computation and ceiling rather than treating every amount withheld as creditable. Section 173(1A) can pass the credit or its balance through specified company distributions to resident individuals or qualifying resident companies, while subsection (7) extends the stated underlying-distribution-tax treatment at not less than one-half of voting power where its treaty-category conditions hold. These are separate tests, not a universal 50% entitlement to foreign tax credit. Section 173(1A), (5)–(7).

For an ordinary illustration with no excess foreign-tax deduction or underlying-tax adjustment, assume independently established total income of £100,000, pre-credit Guernsey tax of £10,000, and eligible foreign income of £20,000. The effective rate is 10% and the domestic ceiling is £2,000. If treaty-eligible foreign tax is £1,500, credit is £1,500 and residual total Guernsey tax is £8,500, assuming no other credits. This does not assert a flat statutory rate or resolve the taxpayer's allowances. Section 173(2)–(6).

The initial claim must be made not later than six years after the end of the relevant year of charge, in the Director's required form and manner; a disputed allowance is appealable like an assessment under Parts VII–VIII. Thus an ordinary 2026 claim reaches that statutory limit on 31 December 2032. If subsequent tax adjustments in Guernsey or elsewhere make an allowed credit excessive or insufficient, subsection (10) overrides ordinary assessment/claim time limits for a resulting assessment or claim made within six years from completion of all material assessments, adjustments and determinations. Record the actual final determining event; a foreign refund is a reason to recompute the credit, not permission to retain the old amount. This statutory rule does not establish a current submission form or any separate reporting deadline for notifying the change. Section 173(9)–(10).

Unilateral relief where no relevant arrangement is in force

Section 176 is a different route. It requires Guernsey residence, Guernsey tax paid or payable, proof to the Director of foreign income tax paid or payable on the same income, and no section 172 arrangement in force for that territory and year. Its relief rate is the lower of the foreign effective rate and three-quarters of the Guernsey effective rate. The Guernsey effective rate is total pre-relief Guernsey tax divided by total income assessable there; determine the foreign rate as nearly as possible on the same principles. Do not apply this 75% ceiling to UK treaty credit or substitute a nominal foreign headline rate for the effective rate. Section 176(1)–(2).

Section 176(3) separately controls foreign-tax deductions and receipt gross-up and allows deduction of foreign tax exceeding the relief. Section 176(1A) passes relief through the specified intermediate-/standard-rate company distributions to the qualifying resident recipients. Establish those facts before computing a company/shareholder case. For a simple no-excess illustration, independently established Guernsey total income of £100,000 and pre-relief tax of £10,000 give 10%; three-quarters is 7.5%. If established eligible foreign income is £10,000 and the foreign effective rate is 5%, relief is £500. This assumes the source-territory/year test and all income bases have been established, with no other adjustments. Section 176(1A)–(3).

The normal unilateral claim period is the two years next following the year of charge. A late claim must be admitted only if it satisfies both the six years next following that year and the six months next following ascertainment of the relevant foreign-tax amount. An ordinary 2026 normal claim therefore runs to 31 December 2028; do not replace that with a universal six-year deadline. Current prescribed submission arrangements and evidence requirements remain to verify. Section 176(4).

Dividends, interest and royalties

Treaty limits constrain the source territory's permitted tax; they do not create a domestic charge or determine the residence territory's tax. Establish the domestic treatment, income category, beneficial owner, treaty residence and Article 23 entitlement before calculating relief. HMRC's summary expressly distinguishes treaty rates from domestic rates. Articles 10–12; DT8602.

Dividends

Article 10(2)(a) generally exempts a dividend from source-territory tax where its beneficial owner is resident in the other territory, subject to the article's exceptions. It does not set a minimum ownership percentage for this ordinary exemption. Residence-territory taxation and tax on the distributing company's profits remain separate. Article 10(1)–(3).

The exception in Article 10(2)(b) concerns dividends from an investment vehicle's directly or indirectly derived immovable-property income/gains where the vehicle distributes most of that income annually and the property income is exempt from tax. Source tax is capped at 15% of the gross dividend. A pension scheme established in the other territory retains the paragraph (a) exemption. Do not apply 15% merely because a company owns a building; establish the vehicle and distribution conditions. Article 10(2)(b).

If the holding is effectively connected with the beneficial owner's permanent establishment in the payer's territory, Article 10(4) refers the matter to Article 7 instead. This is an asset-to-establishment connection test, not simply whether the shareholder has any business presence there. Article 10(4).

Ceiling example: for an established qualifying property-income dividend of £10,000, the treaty ceiling is £1,500. If independently verified domestic source tax would be £2,000, the treaty-limited amount is £1,500, subject to claim procedures. If domestic tax instead is £1,000, the treaty does not raise it to £1,500. No domestic rate is asserted by these assumed figures.

Supplementary regression control retained byte-exact.

Interest and royalties: qualifying owners differ

Articles 11(2) and 12(2) allow source taxation under domestic law unless at least one of their respective paragraph 3 conditions grants residence-only taxation. They do not supply a general reduced percentage for every non-qualifying recipient. For both categories, qualifying routes include an individual, a company with substantial regular trading in its principal share class on a recognised exchange, a company with less than 25% of shares/other rights owned directly or indirectly by non-residents of the recipient's territory, and specified public bodies. A further route requires the competent authority's determination regarding the purpose of establishing/acquiring/maintaining the recipient or conducting its operations. Do not replace that determination with an internal assurance. Articles 11(2)–(4), 12(2)–(4).

Interest has additional express routes, including a pension scheme, bank/building society, the defined unrelated independently dealing financial institution, and specified public-sector payers. Those additional categories are not all repeated in the royalty article. A bank or pension label alone therefore does not establish royalty relief through the interest provision. Verify the exact recipient category under the correct article. Recognised exchanges are specified in Protocol paragraph 3; not every trading platform qualifies. Article 11(3); Article 12(3); Protocol paragraph 3.

For the ownership route, a company with 24% non-resident ownership passes the numeric limb; exactly 25% does not. Count direct and indirect shares or other rights using supported ownership records. Failure of this route does not rule out another paragraph 3 route. For example, 24 of 100 equal shares represent 24%, while 25 represent 25%; no alternative rights or indirect holdings are assumed in this illustration.

Supplementary regression control retained byte-exact.

Interest and royalty source is generally the payer's residence, subject to the relevant permanent-establishment liability/cost-bearing provisions in paragraph 7. Effectively connected debt claims or IP rights require the paragraph 6/Article 7 analysis. Article 12(6)'s published wording refers specifically to paragraph 1; its interaction with paragraph 2 needs case-specific review rather than silently rewriting the treaty. The excessive related-party amount restrictions in paragraph 8 are addressed below. Classification, beneficial ownership, permanent-establishment connection and claim clearance are not established by a payment description alone. Articles 11(5)–(8), 12(5)–(8).

Associated enterprises and corresponding adjustments

Article 9(1) applies where one territory's enterprise participates directly or indirectly in the management, control or capital of the other territory's enterprise, or the same persons participate in both. If their commercial or financial conditions differ from independent-enterprise conditions, profits that would otherwise have accrued can be included and taxed. The article supplies no numeric ownership-percentage safe harbour; identify management/control/capital facts rather than inventing a minimum shareholding. Article 9(1).

Article 9(2) addresses resulting double taxation: where one territory includes and taxes profits already taxed in the other, and those profits satisfy the independent-enterprise condition, the other territory must make an appropriate adjustment to its tax on those profits, considering the Agreement. Authorities consult if necessary. This is not a right to copy a foreign adjustment into a return without establishing its basis, nor a promise that both territories' tax changes will be numerically equal. The domestic claim procedure, evidence standard and deadlines remain to be verified; preserve the Article 25 dispute deadline separately. Article 9(2).

Recommended evidence: identify the transaction and both enterprises, ownership/control links, contracts and actual conduct, the pricing method and comparables, each territory's original profit and tax computations, the assessment adjustment and the amount of overlapping profit. These are working-paper controls, not a verified Guernsey statutory master-file/local-file requirement. The current domestic deduction/anti-avoidance and specific connected-asset rules are now mapped below. Full domestic transfer-pricing/documentation scope remains unreconciled; this corridor Guide does not claim a standalone complete domestic TP regime.

Articles 11(8) and 12(8) separately limit their interest/royalty provisions to the amount that would have been agreed without the stated special relationship. The excess remains subject to domestic law with regard to the Agreement's other provisions. Do not apply an otherwise available treaty exemption to the entire related-party payment without testing the amount. No blanket withholding rate is established by this section. Articles 11(8) and 12(8).

Adjustment illustration: assume an accepted pricing analysis establishes independent-enterprise remuneration of £120,000 for a service priced at £90,000 and that the Article 9 conditions are met. The profit adjustment under review is £30,000. If the same profit was already included in the counterparty's tax base, identify that overlap for the corresponding-adjustment request; do not treat £30,000 as the tax refund. Likewise, if a £50,000 related-party interest payment has an established independent amount of £40,000, separate the £10,000 excess before testing the relevant treaty article. The benchmark figures are assumed evidence, not published safe-harbour prices or rates.

Supplementary regression control retained byte-exact.

Domestic connected-party controls: keep their scope distinct

Current Income Tax Law section 7 denies non-business/private/capital expenses as specified; section 67 gives the Director a broad power to counteract tax avoidance, reduction or deferral, with subsection (5)’s limit for the specified non-resident liability cases. Section 108 separately substitutes open-market pricing for the stated connected/avoidance sales of machinery or plant, subject to its recharge limit and written-election rules. Neither section 67 nor section 108 supplies a general ownership-percentage safe harbour, a universal royalty rate or a verified master-file/local-file requirement. Preserve actual contracts, conduct, pricing evidence, asset cost/unallowed expenditure and commercial purpose; determine the applicable provision before adjusting the return. Income Tax Law ss7, 67, 108.

For a non-resident company, section 47G starts with its listed Guernsey-source income, section 47H limits liability to A (tax deducted/deemed paid/credits on disregarded income) plus B (tax on other income), and section 47I identifies disregarded distributions, interest, royalties and other listed categories. Guernsey land/building income is not the similar-nature disregard, and income included in the taxable profits of a Guernsey PE is not disregarded under section 47I(3). Broker/partnership categories require their separate statutory conditions. Combine this domestic analysis with the applicable treaty restriction, rather than using absence of a treaty PE as proof that every rent or distribution is tax-free. Foreign-company registration uses Form 706 and the corporate Guide’s evidence route. Sections 47G–47I.

Ordinary UK-company PE: domestic base, registration and return sequence

For a UK-resident company entitled to this treaty, establish the Article 5 PE and Article 7 attributable profits first. Reconcile the contracts, people performing functions, asset use, risk decisions, revenue and actual costs to the enterprise accounts. Record the basis of every internal dealing and shared-cost allocation. Article 7(2) does not prescribe a fixed turnover margin or make an unsupported head-office invoice deductible. Treaty Article 7(1)–(4).

1. Identify the domestic section 47G source and screen section 47H/47I disregarded income separately. Interest, royalties or distributions included in taxable PE business profits lose that disregard under section 47I(3). Guernsey property income remains a separate source/treatyArticle 6 analysis.
2. Use the section 6 business accounting period and bridge the supported attributed accounts profit to section 7 commercial profit. Disallow capital, private, non-business and other prohibited charges; replace book depreciation with independently established statutory capital allowances. Apply the ordinary capital-allowance/loss rules and retain each source/rate ledger. An Article 7 allocation does not override domestic deductibility conditions.
3. Classify the income under the actual 0%/10%/20% categories. The ordinary company standard rate is 0%; this does not put a licensed, property or large-retail source at 0%, or remove return duties. Specific finance, minimum-tax and other excluded regimes require their separate method. Sections 6–7,47G–47I,84–86 and Fifth Schedule.
4. Register the foreign company/branch/PE using the currently linked Form 706 (08/21). It requires registration by 14 July after the first calendar year for which a return is required, and instructs submission to revenueservice@gov.gg, subject Foreign Incorporated Company Registration. Complete company/PE identity, activities, period and contact particulars; retain representative authority. Its opening instructions expressly include branches/PEs, but section 6 requires a declaration of central management/control or control in Guernsey. Check that declaration against the actual facts; do not sign either statement unless true. If neither fits the non-resident PE, obtain Revenue Service's completion instructions before submission. The opening PE reference does not permit a false residence/control declaration or settle that completion gap. Form 706, opening instructions and sections 1–6.
5. Complete the company income return and required accounts, identifying the Guernsey source/rate calculation and treaty position. Section 68 applies following the actual individual or published notice even where no tax is payable; its specified period cannot be shorter than 21 days from issue. Section 68AA requires electronic company returns/attachments unless the Director permits another form. The current company page's 30 November 2026 deadline concerns the 2025 return, not an announced deadline for 2026 income. Track that later return's actual notice and assessment instalments using the company filing/payment method. Sections 68,68AA,81; current company page.

Domestic bridge illustration: assume a supported attribution gives £200,000 revenue and £130,000 accounts costs, including £10,000 book depreciation. All other costs qualify, independently established statutory capital allowances are £5,000, and there are no losses or other adjustments. Accounts profit £70,000 + £10,000 depreciation − £5,000 allowances gives £75,000 taxable profit. Established standard-rate income produces £0 tax; the same base in an established 10% category produces £7,500. This compares classifications; it neither establishes either category nor dispenses with the return. Sections 7,84–86 and Fifth Schedule; supplementary controls.

Pensions and government service

Ordinary pensions: subject to Article 18, Article 17 allocates pensions and similar remuneration paid to an individual resident in one territory exclusively to that territory. Establish treaty residence and the payment's actual classification. A Guernsey-resident individual's qualifying ordinary UK pension therefore falls within residence-territory allocation; this does not itself complete a UK withholding-relief claim or establish the Guernsey domestic computation. Do not assume that every lump sum, annuity or withdrawal described as retirement money has the same classification. Article 17.

Government-service payments: Article 18 has a different structure. It concerns remuneration, expressly including pensions, paid by a territory's Government for services to that Government in discharging governmental functions. It exempts that payment in the other territory if the individual is not ordinarily resident there. For remuneration other than a pension, it also allows exemption where the individual is ordinarily resident in that other territory solely to perform those services. The second route is expressly unavailable to pensions. Article 18(1).

Consequently, for a qualifying Guernsey Government pension paid to an individual ordinarily resident in the UK, Article 18 does not provide the UK exemption. Do not apply Article 17's ordinary-pension residence-only wording without resolving the government-service provision. Nor does failure of an exemption condition by itself establish the amount of tax payable: domestic liability and double-tax relief still require analysis. HMRC's UK-resident summary confirms this ordinary-residence distinction for Guernsey government pensions. Article 18; HMRC DT8602.

Article 18(2) excludes payments for services connected with a Government's trade or business carried on for profit from its stated rule. Identify the actual payer, function and service, rather than treating every publicly owned enterprise's payment as government-service remuneration. The article does not introduce a nationality test; a passport is not a substitute for the ordinary-residence enquiry. Article 18.

Classification examples: assume the payer, function and ordinary residence are established. An employee ordinarily resident in the receiving territory solely to perform qualifying governmental services can meet the non-pension route. A pensioner with the same ordinary-residence status cannot use that route because it excludes pensions. These examples apply the treaty conditions; they do not define domestic ordinary residence or establish pension-scheme eligibility.

For a claim, retain residence evidence, pension award and scheme documents, payment breakdown, government employer/service history where relevant, and both territories' deductions and assessments. This is a recommended evidence file. The published ordinary UK pension claim process follows; domestic ordinary-residence meaning, lump-sum/scheme classification and other relief procedures remain explicit limits.

UK ordinary pension relief: form, certification and follow-through

Where Article 17 grants a Guernsey treaty resident relief on an ordinary UK pension, use HMRC's currently published DT-Individual (10/22):

• Complete Parts A/B, the pension particulars in C.1 or C.2, and the signed Part F declaration. Pension relief-at-source applications start after payments begin.
• Send the completed claim to the residence tax authority for certification. Note 4 permits a separate treaty-residence certificate if it will not sign/stamp the form. The certified claim goes to HMRC, Pay As You Earn and Self Assessment, BX9 1AS, United Kingdom, directly or through the claimant as the residence authority's procedure provides.
• Do not enter PAYE pensions in Part D. HMRC handles that refund. Note C.2 uses the latest of residence-tax eligibility, pension commencement and the earliest open repayment year; retain the latest P60.
• Relief at source requires HMRC's decision/notice. Report subsequent information changes without delay, and submit a new DT-Individual for every new income source.

Sources: DT-Individual, Parts C/D/F and Notes 3–4,6,C.2; PAYE81010, new sources. Confirm Article 17/18 classification first; neither the generic form nor an older treaty digest determines entitlement. Exact UK repayment time limits require a separate case/year check; Guernsey credit deadlines are not imported into this process.

Guernsey Form 675: its express pre-2020 population

The current Guernsey forms index still links Form 675 (02/23), “Application for relief from Guernsey income tax”. Its opening sentence limits it to someone who, before 1 January 2020, was UK-resident, Guernsey-non-resident and receiving a pension/similar payment taxable in Guernsey. It requires HMRC residence certification before return to Revenue Service, payer/scheme particulars, and provider evidence of gross income/tax deducted for a refund. Its declaration requires notification if the income stops being subject to UK tax or the claimant becomes Guernsey-resident. This is a verified procedure for that stated population, not a general new-arrival or domestic foreign-tax-credit claim form. Do not apply its stated refund window to sections 173/176 claims. Form 675, both pages.

Students and apprentices: foreign support only

Article 19 covers a student or business apprentice who is, or immediately before visiting was, resident in the other territory, and is present solely for education or training. Payments for maintenance, education or training are exempt in the visited territory only where they arise from sources outside that territory. This does not establish an exemption for local wages or every payment received by someone enrolled on a course. Article 19.

For example, qualifying maintenance support from outside Guernsey and wages from work performed in Guernsey need separate classifications. The student article can cover the former when all its conditions are met; it does not establish relief for the latter. Record the prior residence, purpose of presence, payment source and payment purpose. Apply the employment provisions and domestic rules separately to any earnings.

Capital gains: asset and value tests

Article 13 allocates taxing rights; it does not create a domestic tax charge, valuation method, rate or filing deadline. A resident disposing of immovable property in the other territory can be taxed there. The article also permits that territory to tax gains on shares or comparable interests deriving more than 50% of their value, directly or indirectly, from immovable property there, subject to the traded-share exception. This measures the interests' underlying property value, not the seller's ownership percentage. The article states no 365-day lookback; do not import another treaty's testing period. Article 13(1)–(2).

The exception concerns shares with substantial and regular trading on a recognised stock exchange. Listing alone does not establish that condition. Protocol paragraph 3 names the recognised exchanges, including the London Stock Exchange/AIM and the International Stock Exchange, and allows authority-agreed additions. Unlike the Gibraltar agreement, this paragraph does not state a property-investment-vehicle carve-out from its traded-share exception. Apply this treaty's text and the separate offshore override below. Article 13(2); Protocol paragraph 3.

Value boundary: assume supported valuations, ordinary untraded shares, no offshore activity and no other applicable allocation rule. With total value of £1m and £500,000 derived from relevant property, the ratio is exactly 50% and does not exceed the threshold. At £510,000 of relevant property value, the ratio is 51%, so this value condition is met. Neither result establishes the domestic gain or tax payable.

Movable business property of a PE, including disposal of the PE itself, can be taxed in the PE territory. Gains of an enterprise operating ships or aircraft in international traffic from those vessels/aircraft and associated operating movables are allocated exclusively to its territory. Other gains fall to the alienator's residence territory under Article 13(5), subject to the agreement's other applicable provisions. Article 13(3)–(5).

Offshore activities override the ordinary allocation

Article 21 applies notwithstanding other agreement provisions. Its scope is offshore activity connected with exploration or exploitation of the territory's seabed, subsoil and natural resources; it is not a rule for every overseas company or offshore bank account. The ordinary enterprise rule deems a PE, subject to paragraphs 4–5. Article 21(1)–(3).

The paragraph 4 exception applies where relevant activity totals no more than 30 days in any twelve-month period beginning or ending in the fiscal year concerned. Aggregate substantially similar activity by associated enterprises, excluding simultaneous activity from double counting. Association here concerns participation in management, control or capital, including common participation; the article does not supply a universal 50% ownership threshold. Article 21(4).

Aggregation boundary: assume one enterprise has 22 days and an associated enterprise has 14 substantially similar days, with six overlapping days, in a tested twelve-month window. The total is 22 + 14 − 6 = 30 days. One additional non-overlapping day gives 31 and defeats this particular exception. Check every relevant window and the actual activity facts before reaching a PE conclusion.

Supplementary regression control retained byte-exact.

Paragraph 5 instead allocates specified supply/personnel transport and towing/anchor-handling profits exclusively to the resident's territory. Paragraph 6 allows the activity territory to tax the specified exploration/exploitation-rights income and disposal gains, relevant property gains, and shares whose value or greater part of value derives from those rights/property. The paragraph 4 enterprise-duration exception is not a blanket exemption from paragraph 6. Article 21(5)–(6).

Offshore employment remuneration can be taxed where the duties are performed offshore under paragraph 7; paragraph 8 allocates the specified transport/towing/anchor-handling crew remuneration to the employee's residence territory. Do not substitute the enterprise's 30-day condition for an employee exemption or automatically use the ordinary employment 183-day exception. Article 21(7)–(8).

Retain asset location and valuation support, ownership chains, trading evidence, PE records, rights/contracts, activity dates and overlap, and each territory's domestic computations and filings. This is a recommended evidence structure. Domestic charging rules, valuation dates, disposal reporting and specific offshore fact patterns remain to verify.

Filing, deadlines and disputes

Prepare the domestic returns and relief claims for each applicable year; retain residence evidence, employment-location records, payslips, assessments, proof of tax paid and credit allocation. Sections 173 and 176 supply the domestic relief claim periods and section 173(10) supplies the later-tax-adjustment rule above. The ordinary UK-pension DT-Individual submission/change-notification method above is supplied. Guernsey domestic credit submission forms, any separate domestic change-notification deadline and other payroll clearance remain unverified. Do not stop withholding solely because this working paper identifies potential treaty relief.

Under Article 25(1), a person can present a treaty-inconsistent taxation case to either competent authority within three years from first notification of the action producing that taxation, irrespective of domestic remedies. Record the actual notification and service evidence. Article 25 does not replace domestic appeal or payment deadlines; its competent-authority process is not a promise of immediate refund or suspension. The arbitration conditions and published implementation memorandum are examined below; an official status discrepancy remains unresolved. Article 25.

Guernsey administrative profile: access and limits

Guernsey's OECD-hosted profile, updated 17 March 2025, reports MAP access for transfer-pricing cases, treaty/domestic anti-abuse issues, audit settlements and bona-fide taxpayer-initiated foreign adjustments. It also reports access where domestic remedies were sought or decided. Access does not guarantee relief or override the separate arbitration exclusion for issues already judicially decided. Profile, questions 5–12.

The profile reports no MAP request fee. Collection suspension requires a request: its stated usual conditions include an appeal against the assessment, payment of undisputed tax and reasonableness on the facts. Do not assume submission itself stops collection. Questions 16–17.

For bilateral advance pricing agreements, the profile reports neither a formal legislative programme nor an informal procedure. Its contact list is not proof that such a programme exists. This is a dated administrative statement, not a source-backed determination that domestic transfer-pricing rules are inapplicable. Question 2.

The earlier attempt to retrieve the linked Revenue MAP guidance failed. The currently linked issue 8, dated 12 February 2024, was recovered on 28 October 2026 and supplies the intake methods below. That historical failed receipt is not a current access blocker. Revenue MAP Guidance.

Current linked MAP intake and completeness requirements

Guidance section 7.1 permits hard-copy or electronic requests in English, addressed to Guernsey Competent Authority (MAP Request), International Team, Revenue Service, PO Box 37, St Peter Port, Guernsey GY1 3AZ, or to eoi@gov.gg with the subject MAP Request. It imposes no request fee and requires separate request letters for each case/relevant treaty. No prescribed form is required under section 7.2. These are the linked guidance's submission instructions, not evidence that a particular request has been received or accepted. Guidance 7.1–7.2.

Prepare the required taxpayer/entity identities, both jurisdictions' tax references where applicable, representative authority, treaty and disputed articles, timeliness, transaction/relationship facts, amounts/currencies/exchange rates and evidence, supported treaty analysis and proposed resolution, domestic/treaty deadlines, foreign authority and parallel proceedings/submissions/rulings, and accuracy/cooperation statements. TP cases add foreign taxpayer identities/contact details and relevant documentation; a description of voluminous documentation is accepted as a starting point. This list is the authority's minimum-information framework, not a substitute for checking each applicable item in section 7.2. Guidance 7.2, pp13–16.

Completeness affects the treaty clock. The guidance says a request is not regarded as made until all minimum information has been provided; an incomplete placeholder does not establish timely submission. Additional-information requests normally allow 60 days; agree any extension in advance or the authority can regard the request as withdrawn. Section 7.4 provides acknowledgment within five working days and an endeavour to communicate acceptance/decline within 30 days. Those administrative steps do not extend the treaty's three-year first-notification limit or start Article25's other-authority clock. Guidance 7.2–7.4; treaty Article25.

Guidance 7.7.2 permits consideration of TP corresponding adjustments even where the relevant treaty lacks an Article9(2) equivalent; acceptance and amount still require the actual entitlement. Guidance 7.7.4 distinguishes access after domestic proceedings from the authority's inability to deviate from the relevant Tribunal/highest-court decision. Under 7.7.1, MAP does not automatically suspend collection: use the separate request, assessment appeal and undisputed-payment conditions; amounts ultimately due can attract statutory surcharges. Preserve notices and all procedural clocks. Guidance 7.7.1–7.7.5.

Arbitration: separate clocks and conflicting status evidence

Article 25(5) addresses unresolved issues after the authorities have been unable to resolve a qualifying case within two years from presentation to the other territory's competent authority. That is not the three-year first-notification deadline for presenting the initial MAP case. Retain proof of both events; do not start both clocks from the original assessment or first submission to one authority. Arbitration requires the person's request, and excludes issues already decided by either territory's court or administrative tribunal. Article 25(1), (5).

For example, an initial submission to one authority followed by transmission to the other six months later does not make the treaty's two-year arbitration period expire two years after the initial submission. The relevant starting event is presentation to the other authority. Confirm receipt and the case's procedural position, rather than computing eligibility from an assumed forwarding date. This example does not settle any authority's completeness requirements.

Article 25(2) requires implementation of an agreement reached notwithstanding domestic time limits. That does not waive the initial treaty presentation deadline. Under paragraph 5, the arbitration outcome's binding implementation is subject to the stated acceptance condition. Keep domestic litigation, appeal and collection decisions separate; do not withdraw proceedings on the basis of a draft eligibility analysis. Article 25(2), (5).

Status discrepancy: HMRC's treaty index says the memorandum has not entered into force. However, the published memorandum, paragraph 13.1, takes effect on the later signature date, and both signatures are dated 16 June 2022. Its text supports that effective date; the index conflict and present operational availability require competent-authority confirmation. Neither silently dismiss the signed text nor promise a working arbitration route from it alone.

The published procedure requires a written identifying request to one or both authorities and each requesting/directly affected person's statement that no court or tribunal has decided the same issues. Part 2 requires identities, treaty grounds, facts, years, amounts/calculations, supporting analysis and records of parallel or earlier proceedings. Part 11 requires written acceptance and withdrawal/termination of resolved court issues before implementation. These are published requirements, not evidence that a particular application is accepted. Memorandum, Parts 1–2 and 11.

Before relying on arbitration, obtain the current authority instructions, resolve the status discrepancy, document both treaty clocks, identify any decided issues, and review litigation consequences with the taxpayer. The linked Revenue guidance now supplies MAP submission addresses above; current arbitration-specific intake, case acceptance and any later amendment/termination of the memorandum remain to verify.

Assistance in collecting tax claims

The December 2021 exchange of letters makes Article 27 effective 1 January 2022. Article 28(2)(b) applies it without regard to the taxable period concerned; do not limit assistance to debts for 2022 onwards. This commencement is separate from the unresolved arbitration-status issue above. Exchange of letters; Article 28(2)(b).

Article 27 is not restricted by Articles 1 and 2. Its revenue-claim definition includes taxes of every kind imposed by the territories or their subdivisions/local authorities, provided taxation is compatible with the relevant instruments, plus related interest, administrative penalties and collection/conservancy costs. This broader assistance scope does not create an exemption or alter the substantive tax allocation rules. Article 27(1)–(2).

Distinguish two requests:

• Collection: the requesting territory's claim must be enforceable and owed by someone who cannot prevent collection under its law. The other territory collects under its own enforcement laws as if its own claim.
• Conservancy: the requesting territory must be able to take measures to secure collection under its law. Such measures in the other territory can apply even before enforceability or while the debtor has a right to prevent collection.

Article 27(3)–(4). For example, a right to prevent ordinary collection does not alone prove that asset-preservation assistance is unavailable; check paragraph 4 separately.

Disputes about the claim's existence, validity or amount belong in the originating territory, not the assisting territory's courts or administrative bodies. Under paragraph 5, the assisting territory’s tax-specific time limits and priorities do not apply to an accepted claim, and the originating territory’s priorities are not imported. If the request conditions cease before collection/remittance, the requesting authority must promptly notify the other and suspend or withdraw at that other's option. Article 27(5)–(7).

Paragraph 8 limits mandatory assistance, including incompatible administrative measures, public policy, failure to pursue all reasonable domestic collection/conservancy measures, clearly disproportionate burden, and taxes considered contrary to generally accepted taxation principles. Do not treat a foreign debt notice as proof that every condition is met. Retain the assessment, challenge/collection status and notices; current domestic enforcement procedure and case-specific authority decisions need separate legal review. Article 27(8).

Penalties and interest

No treaty penalty or interest rate is calculated here. Determine domestic late-return, late-payment and inaccurate-claim consequences separately. A treaty claim or mutual-agreement request is not assumed to suspend collection. Keep each territory's filing and payment calendar while seeking relief.

Two worked examples that recompute

1. The 183-day boundary is only one limb. Assume properly counted presence blocks of 90 and 93 days within a tested twelve-month window, with all other relevant windows checked. The total is 183. One additional day gives 184 and fails the numeric condition. In the 183-day case, residence-only treatment still requires the employer and permanent-establishment conditions; a work-territory employer would defeat the exception even at 90 days.

name: Employment presence boundary in one tested rolling window
inputs:
  first_visit_days: 90
  second_visit_days: 93
  additional_day: 1
steps:
  - at_boundary: first_visit_days + second_visit_days
  - over_boundary: at_boundary + additional_day
expected:
  at_boundary: 183
  over_boundary: 184

2. Credit is capped by tax on the same income. Assume treaty eligibility is established, UK tax of £3,000 is properly payable and paid on the relevant income, and the separately verified Guernsey pre-credit tax on that income is £4,000. Credit is £3,000 and residual Guernsey tax is £1,000. If eligible UK tax instead is £5,000, the credit is capped at £4,000 and residual Guernsey tax is £0. The excess £1,000 is not a Guernsey refund generated by this formula. Both tax amounts are assumed inputs; no domestic rate, income allocation or allowance is inferred.

name: Guernsey treaty credit below and above the same-income ceiling
inputs:
  guernsey_precredit_tax: 4000
  lower_eligible_uk_tax: 3000
  higher_eligible_uk_tax: 5000
steps:
  - lower_credit: min(guernsey_precredit_tax, lower_eligible_uk_tax)
  - lower_residual: guernsey_precredit_tax - lower_credit
  - higher_credit: min(guernsey_precredit_tax, higher_eligible_uk_tax)
  - higher_residual: guernsey_precredit_tax - higher_credit
  - excess_over_ceiling: higher_eligible_uk_tax - higher_credit
expected:
  lower_credit: 3000
  lower_residual: 1000
  higher_credit: 4000
  higher_residual: 0
  excess_over_ceiling: 1000

Ask the client first

1. Where is the taxpayer domestically resident, and what home/ties/history evidence resolves any dual residence?
2. Where was employment exercised, on what dates, and across which rolling twelve-month windows?
3. Who is the employer, where is it resident, and which entity or establishment bears the cost?
4. What income and tax do the assessments/payment records cover, and has either authority made an adjustment or refund?
5. When was any disputed taxation first notified, and which domestic appeal/claim deadlines remain open?
