Income Tax in Liechtenstein

Who this applies to

SteG article 6 makes individuals with domestic domicile or habitual abode subject to unlimited wealth/income taxation, subject to the specific exceptions and relief rules. Foreign residents have the specified domestic wealth/income categories; article 7 controls start/end dates. This ordinary-resident 2026 workpaper is not a residence/treaty or special-regime determination. Current source is the Tax Act consolidated 1 July 2026; selected provisions and read limits are below.

Rates, bands and thresholds

Before using the tariff, screen the separate Existenzminimum exemption in SteG article 15(2)(i). For an unlimited-liability resident, article 14 income that does not exceed the applicable minimum is exempt. If only part of the income is domestically taxable, test total income; for liability lasting less than a year, annualise that total. This test is not a further deduction from taxable income and is distinct from the zero band and fixed tariff subtraction. SteG, articles 15(2)(i) and 19

SteV article 8 sets these monthly gross minima, with the amended base amounts first applying to tax year 2025 and continuing in the current 2026 text:

Established category	CHF per month	CHF for a full twelve months
Single	2,100	25,200
Qualifying single parent	2,600	31,200
Jointly assessed spouses/registered partners	3,200	38,400
Separately assessed spouses/registered partners in the same household, or factual cohabiting partners	1,600 each	19,200 each
Each child aged up to 5, additional	300	3,600
Each child aged 6–11, additional	450	5,400
Each child aged 12 or older, additional	600	7,200

Establish the actual family/child category, article 14 total income including relevant deemed wealth yield, and liability period before deciding eligibility. Resolve changing family circumstances or disputed attribution separately; do not replace this gross-income test with post-deduction taxable income x. SteV, article 8 and its amendment notes

For income not exempt under that screen, the following reproduces article 19(1). Values are CHF taxable income x, not gross salary. “Subtract” is the fixed amount in the statutory formula, not another itemised deduction. The tariff's basic allowance is embedded in its zero band and formula. Qualifying single-parent status is the statutory family-law category, not any adult living alone with a child. Special capital/substitute wealth taxation has different rules.

Source for every threshold/rate/subtraction: SteG, article 19. Apply the statutory wealth/income rounding below before the printed tariff; do not interpolate across the endpoints. Final tax rounding and special-assessment application still need the current return instructions.

The base

1. Establish family status, children, residence periods and the applicable assessment route. Article 8 ordinarily combines spouses/registered partners living in an unseparated relationship; its separate-assessment election and child-income rules are distinct. SteV article 6 requires the joint written separate-assessment application/withdrawal by 31 December of the relevant year and at least five years' separate assessment. Do not select the joint tariff merely from one person's marital label. SteG, articles 8 and 18; SteV, article 6
2. Reconcile assets, values and liabilities. Article 9 addresses taxable wealth; articles 10–12 contain exclusions, debt allocation and valuation rules. Foreign property/PE and partly domestic wealth need the actual allocation rules. A negative wealth base or deduction for every worldwide debt is not assumed. Trusts, foundations, valuation disputes and substitute wealth taxation remain specialist cases.
3. For ordinary taxable net wealth, apply the 4% Sollertrag under articles 5 and 14(2)(l), then include that deemed yield in taxable income. Article 15(1) prevents separately taxing actual returns on wealth already subjected to that wealth-tax mechanism. Do not add the same taxed asset's interest/dividend again solely because it appears in a bank statement. The 4% figure is now statutory for 2026, not an annual Finance Act assumption. SteG, articles 5 and 14–15; Act 2024/483, commencement II(2)
4. Reconcile employment, self-employment, property, pensions and other receipts under articles 14–16, with their exclusions and actual deduction conditions. Article 15's private-asset gain exclusions do not decide a business-asset or separate property-gain case. Article 16 governs expenses, losses and personal deductions. The tariff allowance is embedded in the formula; it must not be deducted a second time from the input base.
5. Retain the final established taxable income x, including the applicable deemed wealth yield, before selecting the state formula. Articles 18, 21 and 22 contain part-year/special-income/foreign-relief rules; do not apply the simple full-year examples indiscriminately.

Ordinary wealth and debt workpaper

SteG article 9 starts with all movable and immovable wealth, and attributes a partnership without legal personality to its members. Articles 9(3)–(4) and SteV 7 have separate beneficiary/founder and substitute-payment rules; the ordinary workpaper does not value a trust/foundation interest.

Ordinary step	Statutory method	Official source
Household/personal-use assets and private vehicles	Exclude up to CHF 26,400, or CHF 52,800 for joint spouses, from the combined qualifying value; not a general cash allowance	SteG 10(a)
Necessary occupational/agricultural/business tools	Stated CHF 2,100 limit; establish qualifying articles/value	SteG 10(b)
Other exempt wealth	Article 10 separately lists qualifying public collections, evidenced agricultural products, foreign land and foreign PEs	SteG 10(c)–(f)
Ordinary valuation date	Beginning of tax year or beginning of liability	SteG 12(1)
Quoted securities	Actual quoted price	SteG 12(1)(c)
Unquoted securities, rights and claims	Market value, ordinarily not below nominal unless contrary evidence; disputed/doubtful claims reflect recoverability. Unquoted-security valuation also requires SteV 7a/Annex 1	SteG 12(1)(d); SteV 7a
Recurring rights and private redeemable life insurance	Equivalent arm's-length acquisition value for the stated recurring rights; old-employment pensions excluded from wealth valuation. Redeemable life policies use surrender value plus surplus until maturity	SteG 12(1)(e)–(f)
Land/buildings	Ordinarily earnings value, at least official tax-assessed value	SteG 12(2)
Business assets	Acquisition/production cost less depreciation/value adjustments	SteG 12(3)
Debt	Actual principal-debtor obligations; only the taxpayer's share of joint debt. Where only part of wealth is domestically taxable, allocate debt by domestic-taxable/total wealth ratio; debt cannot make taxable wealth negative	SteG 11

Keep the gross asset schedule, each exemption, date/value proof, total worldwide wealth and debt share/allocation separately. No universal balance-sheet or nominal-value rule replaces the stated classifications. Use the ordinary unquoted-company workpaper below; actual company classifications and values, foreign asset values and disputed/actuarial rights still require their own evidence.

SteG 18(1) rounds wealth down to CHF 100 before conversion into deemed income, and income down to CHF 10. Apply these at the stated bases, retaining the unrounded reconciliation. This is not permission to round each invoice or to invent a final-tax rounding convention. SteG 18(1)

Unquoted company shares: ordinary valuation workpaper

Use SteV 7a and Annex 1 before carrying an unquoted company interest into the wealth schedule. The starting accounts are the last accounts closed before the holder's tax year begins; use consolidated accounts where commercial law requires them. Where the consolidated accounts omit tax-permitted reserves, the ordinance permits corresponding equity and earnings adjustments. The official 2026 helper illustrates valuation at 1 January 2026, ordinarily using 31 December 2025 accounts for a calendar-year company. SteV 7a(3), Annex 1; 2026 helper, opening instructions

First check the exceptions. If the taxpayer proves the ordinary method does not represent market value, SteV 7a(2)(a) permits a different valuation. An actual transfer between independent parties supplies the purchase price as market value under 7a(2)(b), while the company's economic position has not materially changed. Retain the transaction and valuation evidence. SteV 7a(2)

For an operating trading, industrial or service company, prepare these separate steps:

Step	Method	Official source
Substance value S	Reported equity after profit appropriation, plus hidden reserves on participations and taxed hidden reserves. Revalue underlying unquoted-company participations under Annex 1 A(1); if that value is below their carrying value, retain the carrying value	SteV Annex 1 A(3)
Earnings R	Commercial net earnings, adjusted for non-business expenses. Annualise a period shorter or longer than twelve months to twelve months. The authority can adjust results affected by fundamental business changes or exceptional events	SteV Annex 1 A(2)
Earnings value E	max(0, (2 × current annualised R + preceding annualised R) × 0.85 ÷ (3 × K)). The 0.85 factor is the 15% risk deduction. K is 20% for regulated financial institutions and service providers under FMA supervision, 15% for other legal persons	SteV Annex 1 A(2), formula on printed page 34
Operating company value	(2 × E + S) ÷ 3, subject to the non-operating-asset adjustments and minimum below	SteV Annex 1 A(1), formula on printed page 34

For shareholder receivables and non-business assets within SteG 54, remove their value from S for the operating weighting and remove their capitalised net earnings from the earnings component. Add those asset values back in full afterwards. The minimum is 60% of operating substance value plus 100% of those excluded asset values. Keep the asset classification, valuation, related net results and the article 54 reconciliation; do not merely remove the asset's income and leave its value weighted inside S as well. SteV Annex 1 A(1)

Use substance value until a newly formed company has representative results. Holding, finance and property companies, companies in liquidation and inactive companies use substance value under Annex 1 B. Banks and insurers are not finance companies for that exception; classify them under the actual rules before choosing a method or K. SteV Annex 1 A(2), B

Annex 1 C bases the minority deduction on voting rights, for value determined under A: below 20% voting rights gives a 20% deduction; at least 20% but below 50% gives 10%; at least 50% gives zero. Private shareholder agreements do not change that statutory treatment. Establish the holder's economic interest and voting rights separately; do not apply the deduction automatically to an Annex 1 B company or assume unequal capital and voting interests are identical. SteV Annex 1 C

The official helper is supporting calculation material. Its cells F70/G70 use one ownership percentage to allocate value, and J70 uses that same input for the minority lookup. Its P44/P57 formulas round company value down to CHF 100. Keep those form operations distinct from the statutory valuation and from SteG 18's rounding of the taxpayer's total wealth; they do not establish a final-tax rounding rule. Reconcile unusual share classes, consolidated reserves, actual non-operating assets and representative earnings before using the result. 2026 helper, cells F70:K70, P44, P57

Ordinary income deductions and exclusions

Match each receipt to SteG 14–15 before deductions: actual returns on wealth already subject to the wealth mechanism are excluded under 15(1); personal asset gains and business/property/participation gains have different 15(2) gates. Do not turn every credited receipt into taxable salary or every asset disposal into exempt private gain.

Deduction screen	Current statutory rule and boundary	Official source
Ordinary business expenses	Actual business-supported costs under 16(2)(b)(1), not private living costs	SteG 16
Own business-capital interest	Article 16(2)(b)(2) expressly uses the article 5 Sollertrag and imports 12(3) and 54(2)–(6). It does not import 54(1) through that reference. Establish the personal-business capital, valuations and special adjustments; do not automatically copy the corporate no-current-loss rule	SteG 16(2)(b)(2)
Business losses	Evidenced unused prior losses, ordinary 70% current-taxable-income cap; definitive cessation has its stated exception. Foreign PE losses have nonduplication, annual-proof and recapture by earlier 5 years/end unlimited liability	SteG 16(2)(b)(3)–(4)
Employee earning costs	CHF 1,600 ordinary allowance, with the supported extraordinary-cost route below; no duplicate allowance plus full actual costs	SteG 16(2)(c); SteV 12–16
Specified social/accident pensions	70% deduction only for the AHV/IV and accident-invalidity pension categories named in 16(2)(d), not every occupational pension	SteG 16(2)(d)
Eligible child	CHF 12,700, with actual custody/support/education conditions, no conflicting maintenance deduction and half each for the stated jointly held custody/separate assessment	SteG 16(3)(a)
Legal maintenance/support	Actual payments in the specified spouse/parent/legal-support categories	SteG 16(3)(b)
Own statutory insurance	Actual own AHV/IV/FAK/ALV/mandatory-accident contributions under the stated provision	SteG 16(3)(c)
Private life/health/other qualifying accident premiums	Actual qualifying payments capped at CHF 3,700, CHF 7,400 for joint spouses, plus CHF 2,200 per eligible child	SteG 16(3)(d)
Recognised occupational pension	Qualifying one-off/current contributions, capped at 18% of the expressly listed article 14(2)(a,b,c,d,f) income categories	SteG 16(3)(e)
Child education	Actual eligible evidenced costs capped at CHF 12,700 per child/year, less scholarships; primary/secondary/domestic music school and permanently employed-child exclusions apply	SteG 16(3)(f)
Uninsured medical/accident/dental	Qualifying unreimbursed costs capped at CHF 6,300 per person. Costs over CHF 300 per person require receipts; CHF 300 is not stated as a deduction from every claim	SteG 16(3)(g)
Qualifying donations	Stated eligible recipients and 10% pre-business-loss taxable-income limit; individual gifts not exceeding CHF 100 are excluded. Total donations over CHF 300 require evidence. This is not 10% of gross salary; establish the prescribed cap base before calculation	SteG 16(3)(h)
Occupational education/retraining	Actual eligible costs capped at CHF 12,700, with a first secondary-II qualification or the stated age 20/first-qualification exclusion conditions	SteG 16(3)(i)
Part-year and disallowed expenses	Fixed-franc 16(2)–(3) deductions are proportional to duration. Private living/status costs, private damage insurance and direct/indirect taxes are not deductible	SteG 16(4)–(5)

Agricultural yield-unit/accounting elections, corporate-rule cross-references in 16(6), special capital pensions, indirect participations and disputed cap bases require their complete applicable chain. The table supplies ordinary screens, not automatic entitlement or a universal deduction order.

Employee earning costs: allowance versus supported excess

SteV 12 uses CHF 1,600 as the ordinary earning-cost allowance. If qualifying evidenced costs exceed it, only the excess is added under 12(2), producing the supported total rather than CHF 1,600 plus that full total. Articles 13–16 identify commuting and additional outside meals as the extraordinary categories. SteV 12–16

For the article 14(1) commuting route, document the average home/work distance and actual eligible days. Recognise one return trip per day, at most 200 km per day, and at most 220 days/year, or 200 days for teachers. Apply CHF 0.50/km to the first 10,000 annual eligible kilometres and CHF 0.40/km above 10,000. Domestic home/work locations also have the article 14(2)/Annex 2 lump-sum route, with stated teacher, part-time and part-year reductions; do not claim both routes. Employer payment of the full commute excludes the deduction; a partial contribution is wage income with the full cost deduction, and passenger reimbursements reduce uncovered costs. SteV 14

For qualifying meals where work is outside the place of residence, SteV 16 gives CHF 1,100 for 220 days, or CHF 1,000 for 200 teacher days. Employer canteen availability or employer cost contributions exclude that deduction; cash contributions are wage income. Reduce the allowance for part-time/non-full-year employment as required. Establish actual eligibility before adding meals to the commuting workpaper. SteV 16

Municipality, business losses and payroll credits

Article 75 sets the municipality surcharge as a percentage of state tax, fixed annually by the municipality, legally between 150% and 250%. This is not 150%–250% of taxable income. Obtain the municipality's rate for the year. Article 75(2) excludes an added surcharge on source withholding under article 25. Do not add a municipality percentage to the wage-tax deduction itself. SteG, article 75

For an ordinary assessment with the municipality's surcharge m:

municipality tax = state tax × m
combined tax before credits = state tax + municipality tax

For business losses under article 16(2)(b)(3), assess prior unused loss evidence and the ordinary 70% current-taxable-income cap; the year of definitive business cessation has a separate exception. A multiplication using an assumed loss register is not proof of entitlement. The personal capital-interest rule itself refers to article 54(2)–(6), as distinguished above; no broader corporate-rule import is assumed. SteG, article 16

Resident wages also have payroll withholding; use li-payroll-social for its distinct base and instructions. Article 29 credits withholding in an ordinary assessment and addresses excess amounts. Preserve wage certificates and all prepayments, relief and final assessment data before deciding a balance/refund; a payroll percentage is not the final state/municipality tariff. SteG, articles 24–29

Retained predecessor workpapers

Further cases, recomputed with the tariff above (the minimum-income case is the first worked example below):

• Ordinary case: CHF 80,000 other taxable income plus 4% of CHF 500,000 taxable wealth gives CHF 100,000 income, CHF 3,256 state tax and CHF 8,140 combined tax with an assumed 150% municipal surcharge.
• Joint case: CHF 200,000 established joint income gives CHF 6,512 state tax and CHF 18,233.60 combined with an assumed 180% surcharge.
• Qualifying single parent: CHF 150,000 established income gives CHF 4,884 state tax and CHF 14,652 combined with an assumed 200% surcharge.
• Ordinary business loss: CHF 100,000 relevant positive income and CHF 90,000 established unused losses permits CHF 70,000 use and leaves CHF 20,000 losses. Definitive cessation and other special cases are excluded.

The municipal surcharges in these cases are assumptions, not the 2026 rates of any municipality.

Deadlines and filing

Article 94 requires truthful, complete, signed filing even without a personal form/notice. The filing date for 2026 income is the one set in the tax administration's 2026 return documents; on 30 October 2026 the authority's page listed only the 2025 forms and guidance, so take the date from the 2026 invitation when it is issued. Obtain the current return and deduction/election instructions and supporting account, asset, family and foreign-income evidence.

SteV 39 requires the applicable accounts/data sheet, foreign-property acquisition/official values, participation valuations, certificates, deduction evidence and agricultural workpaper/accounts where corresponding entries are made. Under SteV 40, a reasoned written extension request goes to the responsible municipal tax office before the ordinary filing deadline, for at most five months. An extension over one month requires an advance payment of 80% of the prior-year tax. It is not an automatic change to payment maturity. SteV 39–40

The authority's current eTax page recommends preparing the individual return in eTax and permits electronic transmission with attachments. Retain actual year-specific forms, representation/access, receipts and any extension decision. Current eTax instructions; current forms index

Penalties and interest

Article 114 generally requires payment within 30 days of legal maturity, subject to its exceptions; the actual assessment/delivery and special-departure facts matter. SteV article 45 sets late interest at 4%, while the precise start/base and actual notice must be established. Article 135's procedural fines require its post-reminder intentional/negligent breach, with ordinary CHF 1,000 and serious/repeat CHF 10,000 maxima. These are not automatic filing charges. Exact interest day-count and appeals/correction application remain incomplete; the ordinary extension method is supplied above. SteG, articles 94, 113–114 and 135; SteV, article 45

Cross-border points

For part-domestic liability, SteG 18(1a) distinguishes directly connected deductions from its ratio/foreign-law treatment of other deductions and uses the worldwide wealth/income rate. Article 15(2)(i) separately uses total annualised income for the minimum-income screen. Do not apply the ordinary resident example to a treaty/nonresident/part-year case. Use the cross-border skill for the separate domestic, treaty, foreign-credit and claim methods and their explicit application gaps. SteG 15(2)(i), 18, 21–23

Two worked examples that recompute

Minimum-income exemption screen

Assume an unlimited-liability single resident for the full year, no child addition and CHF 24,000 total article 14 income after including every relevant source and deemed wealth yield. The CHF 25,200 annual minimum exceeds that established total by CHF 1,200. Article 15(2)(i) therefore exempts this income; do not compute a positive tariff liability merely because a post-deduction figure falls above the zero band. The arithmetic below checks the threshold and headroom; statutory eligibility is an express case assumption.

Employee costs feed the taxable-income base once

Assume a full-year ordinary-tariff employee, CHF 90,000 established taxable gross wages, and 220 eligible days with a documented 60 km daily return commute under SteV 14(1). No commute reimbursement/passenger contribution applies. The 13,200 km give CHF 5,000 for the first 10,000 km plus CHF 1,280 for the rest. Assume the full CHF 1,100 outside-meal allowance is eligible, with no employer canteen or meal support. Total supported earning costs are CHF 7,380, exceeding the CHF 1,600 allowance; do not claim CHF 8,980.

Assume actual eligible own statutory insurance CHF 5,000, private premiums CHF 2,500 and recognised occupational contributions CHF 7,000, with the stated pension cap base CHF 90,000. The pension ceiling is CHF 16,200, so all CHF 7,000 is allowed. With no other income/deduction and CHF 300,000 established taxable net wealth, employment after deductions is CHF 68,120;4% wealth yield adds CHF 12,000. Rounded taxable income is CHF 80,120; state tax is CHF 2,262. An assumed 150% municipal surcharge gives CHF 5,655 combined before credits. With CHF 5,000 established total withholding credit, already including any applicable withholding interest, the assumed balance is CHF 655. This does not decide real asset values, reimbursement, pension eligibility, town rate or final assessment. SteG 5, 16, 18–19, 29, 75; SteV 12–16
