CRITICAL: Denmark has NO reduced VAT rates. Every taxable supply is at 25%. There is no 5%, 7%, 12%, or 13% rate. Any suggestion of a reduced rate is wrong.

Key Momsangivelse rubrik (boxes):

Rubrik	Meaning
1	Output VAT (udgående moms) — total VAT charged on sales
2	VAT on EU acquisitions of goods (EU-varekøb)
3	VAT on services purchased abroad with reverse charge (ydelser købt i udlandet med omvendt betalingspligt)
4	Input VAT (indgående moms) — total deductible VAT on purchases
5	Derived: VAT payable / refundable (rubrik 1 + 2 + 3 − 4)
6	Sales excl. VAT (momspligtig omsætning) — value of taxable supplies
7	EU supplies of goods and services excl. VAT (EU-varesalg og ydelser)
8	Exports excl. VAT (eksport)
9	EU acquisitions of goods excl. VAT (EU-varekøb uden moms)

Conservative defaults — Denmark-specific values for the universal categories in vat-workflow-base Section 2:

Ambiguity	Default
Unknown rate on a sale	25% (only rate available)
Unknown VAT status of a purchase	Not deductible
Unknown counterparty country	Domestic Denmark
Unknown B2B vs B2C status for EU customer	B2C, charge 25%
Unknown business-use proportion (vehicle, phone, home office)	0% recovery
Unknown SaaS billing entity	Reverse charge from non-EU (rubrik 3/4)
Unknown blocked-input status (entertainment, personal use)	Blocked
Unknown whether transaction is in scope	In scope

Red flag thresholds — country slot values for the reviewer brief in vat-workflow-base Section 3:

Threshold	Value
HIGH single-transaction size	DKK 25,000
HIGH tax-delta on a single conservative default	DKK 1,500
MEDIUM counterparty concentration	>40% of output OR input
MEDIUM conservative-default count	>4 across the return
LOW absolute net VAT position	DKK 40,000

Section 2 — Required inputs and refusal catalogue

Required inputs

Minimum viable — bank statement for the period in CSV, PDF, or pasted text. Must cover the full period. Acceptable from any Danish or international business bank: Danske Bank, Nordea DK, Jyske Bank, Sydbank, Spar Nord, Arbejdernes Landsbank, Nykredit, Revolut Business, Wise Business, or any other.

Recommended — sales invoices for the period (especially for intra-EU B2B supplies and exports), purchase invoices for any input VAT claim above DKK 1,500, the client's CVR/SE number and momsregistreringsnummer.

Ideal — complete invoice register, prior period momsangivelse, reconciliation of any carry-forward credit.

Refusal policy if minimum is missing — SOFT WARN. If no bank statement is available at all → hard stop. If bank statement only without invoices → proceed but record in the reviewer brief: "This momsangivelse was produced from bank statement alone. The reviewer must verify, before approval, that input VAT claims above DKK 1,500 are supported by compliant tax invoices and that all reverse-charge classifications match the supplier's invoice."

Denmark-specific refusal catalogue

These refusals apply on top of the EU-wide refusals in eu-vat-directive Section 13 (R-EU-1 through R-EU-12). If any trigger fires, stop, output the refusal message verbatim, end the conversation.

R-DK-1 — Lønsumsafgift-only entity. Trigger: client is not VAT-registered but subject to payroll tax on exempt activities. Message: "Lønsumsafgift (payroll tax on exempt activities) is a separate tax from moms. This skill covers momsangivelse only. Please consult a statsautoriseret revisor for lønsumsafgift obligations."

R-DK-2 — VAT group (fællesregistrering). Trigger: client is part of a VAT group under momsloven §47(4). Message: "VAT groups under fællesregistrering require consolidation across all group members. Out of scope for this skill."

R-DK-3 — Fiscal representative. Trigger: non-resident supplier with a fiscal representative in Denmark. Message: "Non-resident registrations with fiscal representatives have specific obligations beyond this skill. Please use a statsautoriseret revisor."

R-DK-4 — Construction reverse charge (§46(1) nr. 3). Trigger: client is a construction subcontractor where the reverse charge under §46(1) nr. 3 applies. Message: "Construction reverse charge under momsloven §46(1) nr. 3 requires transaction-level analysis of whether the customer is a registered builder. This is Tier 2 — flag for reviewer with specific construction details."

R-DK-5 — Partial exemption (pro-rata). Trigger: client makes both taxable and exempt-without-credit supplies and the exempt proportion is non-de-minimis. Message: "You make both taxable and exempt supplies. Input VAT must be apportioned under momsloven §38. Please use a statsautoriseret revisor to determine and confirm the pro-rata rate."

R-DK-6 — Income tax return instead of moms. Trigger: user asks about annual income tax return, not the momsangivelse. Message: "This skill only handles the momsangivelse. For Danish income tax, use the appropriate income tax skill."

R-DK-7 — Used goods margin scheme (brugtmoms). Trigger: client deals in second-hand goods under the brugtmoms scheme. Message: "Margin scheme (brugtmoms) transactions require transaction-level margin computation. Out of scope."

Section 3 — Supplier pattern library (the lookup table)

This is the deterministic pre-classifier. When a transaction's counterparty matches a pattern in this table, apply the treatment from the table directly. Do not second-guess. Do not consult Tier 1 rules — the table is authoritative for patterns it covers.

How to read this table. Match by case-insensitive substring on the counterparty name as it appears in the bank statement. If multiple patterns match, use the most specific. If none match, fall through to Tier 1 rules in Section 5.

Note on Danish representation (repræsentation): Unlike Malta's hard block, Denmark allows 25% recovery of VAT on business entertainment (restauration) under momsloven §42(2). However, this requires proper documentation (business purpose, attendees). Default: block fully. [T2] flag if client claims business entertainment — reviewer must verify documentation meets §42(2).

Section 4 — Worked examples

These are six fully worked classifications drawn from a hypothetical bank statement of a Denmark-based self-employed IT consultant. They illustrate the trickiest cases.

Example 1 — Non-EU SaaS reverse charge (Notion)

Input line: 03.04.2026 ; NOTION LABS INC ; DEBIT ; Monthly subscription ; USD 16.00 ; DKK 109.52

Reasoning: Notion Labs Inc is a US entity (Section 3.9). No VAT on the invoice. Services received from abroad — reverse charge under momsloven §46(1) nr. 1. Both output VAT (rubrik 3) and input VAT (rubrik 4) must be reported. Net effect zero for a fully taxable business. The 25% VAT on DKK 109.52 = DKK 27.38.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Rubrik (output)	Rubrik (input)	Default?	Question?	Excluded?
03.04.2026	NOTION LABS INC	-109.52	-109.52	27.38	25%	3	4	N	—	—

Example 2 — EU service, reverse charge (Google Ads)

Input line: 10.04.2026 ; GOOGLE IRELAND LIMITED ; DEBIT ; Google Ads April 2026 ; -6,350.00 ; DKK

Reasoning: Google Ireland Limited is an IE entity — EU reverse charge. Services purchased abroad, rubrik 3 for the output VAT amount (DKK 1,587.50) and rubrik 4 for the input VAT. Also report the net in rubrik 7 for EU sales list purposes if this is the reporting entity (but for the momsangivelse, rubrik 3/4 is sufficient). Net cash effect zero for a fully taxable business.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Rubrik (output)	Rubrik (input)	Default?	Question?	Excluded?
10.04.2026	GOOGLE IRELAND LIMITED	-6,350.00	-6,350.00	1,587.50	25%	3	4	N	—	—

Example 3 — Entertainment, limited deduction

Input line: 15.04.2026 ; RESTAURANT MARCHAL ; DEBIT ; Client dinner ; -1,800.00 ; DKK

Reasoning: Restaurant transaction. Business entertainment (repræsentation) under momsloven §42(2) allows recovery of 25% of the VAT amount. The full invoice is DKK 1,800 incl. 25% VAT. Net = DKK 1,440. VAT = DKK 360. Recoverable = 25% of DKK 360 = DKK 90. However, this requires documented business purpose and attendee list. Default: block fully. [T2] flag — reviewer must verify documentation.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Rubrik	Default?	Question?	Excluded?
15.04.2026	RESTAURANT MARCHAL	-1,800.00	-1,800.00	0	—	—	Y	Q1	"Entertainment: blocked — 25% partial recovery possible under §42(2) if documented"

Example 4 — Capital goods (high-value purchase)

Input line: 18.04.2026 ; DUSTIN A/S ; DEBIT ; Invoice DK2026-441 Dell XPS 15 ; -12,495.00 ; DKK

Reasoning: Domestic purchase from a Danish vendor. DKK 12,495 incl. 25% VAT. Net = DKK 9,996. VAT = DKK 2,499. This exceeds the capital goods threshold and will be subject to the 5-year adjustment period (investeringsgoder) under momsloven §43-44 if it qualifies as a capital good (purchase price excl. VAT > DKK 100,000 for goods). At DKK 9,996 net, this is below the DKK 100,000 capital goods scheme threshold — treat as normal overhead input VAT in rubrik 4.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Rubrik	Default?	Question?	Excluded?
18.04.2026	DUSTIN A/S	-12,495.00	-9,996.00	-2,499.00	25%	4	N	—	—

Example 5 — EU B2B service sale (inbound receipt)

Input line: 22.04.2026 ; STUDIO KREBS GMBH ; CREDIT ; Invoice DK-2026-018 IT consultancy March ; +26,250.00 ; DKK

Reasoning: Incoming DKK 26,250 from a German company. The client provides IT consulting services to a German B2B customer. Place of supply for services is Germany (customer's country) under the general rule. The client invoices at 0%, the German customer accounts for reverse charge. Report net in rubrik 7 (EU supplies). No output VAT in rubrik 1. Confirm: (a) customer is VAT-registered — verify German USt-IdNr on VIES; (b) the invoice shows no Danish moms.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Rubrik	Default?	Question?	Excluded?
22.04.2026	STUDIO KREBS GMBH	+26,250.00	+26,250.00	0	0%	7	Y	Q2 (HIGH)	"Verify German USt-IdNr on VIES"

Example 6 — Motor vehicle, partial deduction

Input line: 28.04.2026 ; JYSK BILCENTER ; DEBIT ; Car lease payment April ; -4,500.00 ; DKK

Reasoning: Car lease payment. Denmark allows partial VAT recovery on vehicles used for business — but only for commercial vehicles (varebiler/lastbiler). For passenger cars used for mixed business/private purposes, VAT deduction is generally not available unless the car is leased and used for business, in which case partial deduction may apply under momsloven §41(1) for leased passenger cars (1/3 of lease VAT deductible if car cost > DKK 160,000). Default: block fully. [T2] flag — reviewer must determine vehicle type and applicable deduction rule.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Rubrik	Default?	Question?	Excluded?
28.04.2026	JYSK BILCENTER	-4,500.00	-4,500.00	0	—	—	Y	Q3	"Vehicle: blocked — partial recovery may apply under §41 for leased passenger cars"

Section 5 — Tier 1 classification rules (compressed)

Each rule states the legal source and the rubrik mapping. Apply silently if the data is unambiguous.

5.1 Standard rate 25% (momsloven §33)

The ONLY rate for all taxable supplies in Denmark. There are no reduced rates. Sales → rubrik 1 (VAT), rubrik 6 (net). Purchases → rubrik 4 (input VAT).

5.2 Zero rate (momsloven §34)

Exports outside EU → rubrik 8 (net, requires export evidence). Intra-EU B2B supplies of goods → rubrik 7 (net, requires customer VAT number verified on VIES, transport proof). Intra-EU B2B services → rubrik 7 (place of supply is customer's country, no Danish VAT). Newspapers and periodicals → 0% from 2024.

5.3 Exempt without credit (momsloven §13)

Medical services, dental care, social services, education, financial services, insurance, postal universal service, certain cultural/sporting events, residential rent, passenger transport. These supplies are excluded from the momsangivelse — no output VAT, no input VAT deduction on related costs. If exempt supplies are significant → R-DK-5 refuses.

5.4 Local standard purchases

Input VAT on a compliant tax invoice (faktura) from a Danish supplier is deductible at 25%. Rubrik 4 (input VAT). Subject to blocked-input rules (5.8).

5.5 Reverse charge — services received from abroad (momsloven §46(1) nr. 1)

When the client receives a service from an EU or non-EU supplier: compute 25% VAT on the net amount. Report output VAT in rubrik 3. Report same amount as input VAT in rubrik 4. Net cash effect zero for a fully taxable business. If the foreign supplier incorrectly charged their local VAT, that foreign VAT is NOT recoverable through the Danish return — must be reclaimed via EU refund procedure.

5.6 Reverse charge — EU goods acquisitions (momsloven §46(1) nr. 4)

Physical goods from an EU supplier: compute 25% VAT. Report output VAT in rubrik 2. Report input VAT in rubrik 4. Net value in rubrik 9.

5.7 Import VAT — goods from outside EU

Goods imported from non-EU countries: import VAT is settled on the momsangivelse (importmomsordningen — Denmark shifted import VAT reporting to the VAT return from 2015). Report in rubrik 4 as input VAT when the import VAT has been charged. The customs declaration (enhedsdokument) is the supporting document.

5.8 Blocked input VAT (momsloven §42)

The following categories have restricted or zero VAT recovery:

• Entertainment/representation: 25% of VAT recoverable under §42(2), requires documentation of business purpose and attendees
• Hotel accommodation for business: 100% deductible (changed from 75% — now fully deductible)
• Motor vehicles: passenger cars generally blocked; vans/trucks used for business fully deductible; leased passenger cars partial deduction under §41
• Tobacco and spirits: blocked §42(1) nr. 5-6
• Private use: fully blocked §42(1) nr. 1
• Natural gas, electricity for non-business purposes: blocked

5.9 Capital goods scheme (momsloven §43-44)

Capital goods with acquisition cost excl. VAT ≥ DKK 100,000 are subject to the capital goods adjustment scheme. Adjustment period: 5 years for movable goods, 10 years for immovable property (real estate). Below DKK 100,000: treat as normal overhead in rubrik 4.

5.10 Sales — local domestic

Charge 25%. Report VAT in rubrik 1, net in rubrik 6. No B2B/B2C distinction for domestic supplies.

5.11 Sales — cross-border B2C

Goods to EU consumers above €10,000 EU-wide threshold → R-EU-5 (OSS refusal) from eu-vat-directive fires. Digital services to EU consumers above €10,000 → same. Below threshold → Danish VAT at 25%, rubrik 1/6.

5.12 Lønsumsafgift interaction

Businesses making exempt supplies under §13 may be subject to lønsumsafgift (payroll tax on exempt activities). This is a separate return filed separately. If the client makes only taxable supplies, lønsumsafgift does not apply. If the client makes exempt supplies, R-DK-1 or R-DK-5 may fire.

Section 7 — Excel working paper template (Denmark-specific)

The base specification is in vat-workflow-base Section 3. This section provides the Denmark-specific overlay.

Sheet "Transactions"

Columns A–L per the base. Column H ("Rubrik code") accepts only valid momsangivelse rubrik codes from Section 1 of this skill (1–9). Use blank for excluded transactions. For reverse-charge transactions, enter both the output rubrik (e.g. 3) and input rubrik (e.g. 4) separated by a slash in column H.

Sheet "Box Summary"

One row per rubrik. Denmark's form is simpler than most EU countries — only 9 boxes.

Sheet "Return Form"

Final momsangivelse-ready figures. The bottom-line cell is rubrik 5:

Rubrik 5 = Rubrik 1 + Rubrik 2 + Rubrik 3 − Rubrik 4

Positive rubrik 5 → payable to Skattestyrelsen.
Negative rubrik 5 → refund to the business.

Color and formatting conventions

Per the xlsx skill: blue for hardcoded values from the bank statement, black for formulas, green for cross-sheet references, yellow background for any row where Default? = "Y".

Mandatory recalc step

After building the workbook, run:

python /mnt/skills/public/xlsx/scripts/recalc.py /mnt/user-data/outputs/denmark-vat-<period>-working-paper.xlsx

Section 8 — Denmark bank statement reading guide

Follow the universal exclusion rules in vat-workflow-base Step 6, plus these Denmark-specific patterns.

CSV format conventions. Danske Bank exports use semicolon delimiters with DD.MM.YYYY dates. Nordea DK exports use comma delimiters. Common columns: Dato, Tekst, Beløb, Saldo. Jyske Bank includes a Posteringstype column. Always confirm date format and delimiter before parsing.

Danish language variants. Some descriptions appear in Danish: husleje (rent), løn/gage (salary), rente (interest), overførsel (transfer), hævning (withdrawal), indbetaling (deposit). Treat as English equivalents.

Internal transfers and exclusions. Own-account transfers between the client's Danske Bank, Nordea, Revolut accounts. Labelled "overførsel", "intern overførsel", "egne konti". Always exclude.

Owner draws. A self-employed sole trader (enkeltmandsvirksomhed) cannot pay themselves a salary — any transfer to their personal account is a drawing. Exclude.

Refunds and reversals. Identify by "refundering", "tilbageførsel", "kreditnota". Book as negative in the same rubrik as the original transaction.

Foreign currency transactions. Convert to DKK at the transaction date rate. Use the Danmarks Nationalbank rate or the rate shown on the bank statement.

IBAN country prefix. DK = Denmark. IE, LU, NL, FR, DE = EU. US, GB, AU, CH = non-EU.

Section 9 — Onboarding fallback (only when inference fails)

The workflow in vat-workflow-base Section 1 mandates inferring the client profile from the data first (Step 3) and only confirming with the client in Step 4. The questionnaire below is a fallback.

9.1 Entity type and trading name

Inference rule: sole traders (enkeltmandsvirksomhed) often match account holder name; company names end in "ApS", "A/S", "I/S", "K/S". Fallback: "Are you a sole trader (enkeltmandsvirksomhed), ApS, A/S, or partnership?"

9.2 VAT registration status

Inference rule: if asking for a momsangivelse, they are VAT-registered. Fallback: "Are you momsregistreret (VAT-registered)?"

9.3 CVR/SE number and VAT number

Inference rule: CVR numbers sometimes appear in payment descriptions. Fallback: "What is your CVR/SE number and momsregistreringsnummer? (DK + 8 digits)"

9.4 Filing period and frequency

Inference rule: first and last transaction dates. Fallback: "Which period does this cover? Monthly, quarterly, or half-yearly?"

9.5 Industry and sector

Inference rule: counterparty mix, sales descriptions. Fallback: "In one sentence, what does the business do?"

9.6 Employees

Inference rule: ATP, A-skat, løn outgoing transfers. Fallback: "Do you have employees?"

9.7 Exempt supplies

Inference rule: medical/financial/educational income patterns. Fallback: "Do you make any VAT-exempt sales?" If yes and non-de-minimis → R-DK-5 refuses.

9.8 Credit brought forward

Inference rule: not inferable from single period. Always ask. Question: "Do you have any excess credit (tilgodehavende) from the previous period?"

9.9 Cross-border customers

Inference rule: foreign IBANs on incoming. Fallback: "Do you have customers outside Denmark? EU or non-EU? B2B or B2C?"

9.10 Vehicle type

Inference rule: not inferable from bank data. Fallback: "Do you use a vehicle for business? Is it a passenger car (personbil) or commercial vehicle (varebil/lastbil)?"

Section 10 — Reference material

Validation status

This skill is v2.0, rewritten in April 2026 to align with the three-tier Accora architecture (vat-workflow-base + eu-vat-directive + country skill). Awaiting validation by a statsautoriseret revisor or registreret revisor in Denmark.

Sources

Primary legislation:

1. Momsloven (Consolidated VAT Act) — https://www.retsinformation.dk
2. Momsbekendtgørelsen (VAT Executive Order)
3. Opkrævningsloven (Collection Act)

Skattestyrelsen guidance: 4. TastSelv Erhverv momsangivelse form — https://skat.dk 5. Skattestyrelsen guidance on reverse charge (omvendt betalingspligt) 6. Skattestyrelsen VAT registration thresholds

EU directive (loaded via companion skill): 7. Council Directive 2006/112/EC — implemented via eu-vat-directive companion skill 8. Council Implementing Regulation 282/2011

Other: 9. VIES validation — https://ec.europa.eu/taxation_customs/vies/ 10. Danmarks Nationalbank exchange rates

Known gaps

1. The supplier pattern library covers the most common Danish and international counterparties but not every local business.
2. Construction reverse charge (§46(1) nr. 3) is flagged as Tier 2 — a future version should add detailed construction classification rules.
3. Lønsumsafgift interaction is mentioned but not fully specified — out of scope for this VAT-only skill.
4. The capital goods threshold (DKK 100,000 excl. VAT) is the statutory amount as of April 2026. Verify annually.
5. Hotel accommodation VAT recovery (100% deductible) should be verified against current legislation.
6. The 25% entertainment recovery rule under §42(2) requires careful documentation — the skill defaults to block.
