Denmark Tax Treaties Guide

Denmark's Treaty Network Overview

Denmark's tax treaty policy is coordinated with the other Nordic countries (Finland, Iceland, Norway, Sweden) under the Nordic Treaty framework, though Denmark also negotiates bilaterally. Key characteristics:

• Treaties in force: ~100+ comprehensive double taxation treaties, covering all EU/EEA states, OECD members, and major trading partners including the US, China, India, Japan, Brazil, and Russia (suspended post-2022 for Russian transactions).
• Nordic Convention: The Nordic Treaty (Finland, Iceland, Norway, Sweden) has special rules including broader PE definitions, lower/no withholding rates, and specific provisions for cross-border commuting and pension taxation.
• OECD Model basis: Most Danish treaties follow the OECD Model Convention (2017 version for newer treaties). The Commentaries are given significant weight by Danish courts and Skattestyrelsen in treaty interpretation (højesteretspraksis confirms this).
• Multilateral Instrument (MLI): Denmark ratified the MLI in 2019. It modifies approximately 70+ Danish treaties. Key changes: Principal Purpose Test (PPT) replaces or supplements preamble language, revised PE definition (Article 5), and mandatory binding arbitration for MAP. See the MLI section below for Denmark's specific positions.
• Treaty override: Denmark applies the principle that domestic law can override treaty provisions only if the Danish Parliament explicitly legislates to that effect. In practice, Danish courts give strong precedence to treaty provisions (the "treaty-friendly" approach).

Key Treaty Provisions for Businesses

Dividends (Article 10)

• Participation exemption (Danish domestic law): Dividends from subsidiaries (≥10% ownership, ≥12-month holding period) are tax-exempt for Danish corporate recipients under SEL §13. This applies to both Danish and treaty-resident subsidiaries. For foreign corporate recipients, Danish domestic law provides a corresponding exemption under SEL §2, stk. 1, litra c if the recipient would qualify under a treaty.
• Treaty withholding rates: Typically 0% for ≥10% holdings (e.g., UK, Germany, France, Netherlands, Switzerland). 5% for ≥10% holdings in some older treaties. 15% for portfolio holdings (<10%) — this is the standard reduced rate. The Nordic Treaty: 0% in most cases. US Treaty: 5% for ≥10% voting stock, 15% for portfolio. Check the specific treaty — some require a 12-month holding period before the reduced rate applies.
• Limitation on Benefits (LOB): The US treaty (Article 22) has a comprehensive LOB clause. The MLI's PPT applies to ~50 Danish treaties. Ensure the recipient has substance and is not treaty-shopping.
• Beneficial ownership: Reduced treaty rates require the recipient to be the beneficial owner of the dividend. Danish case law (e.g., SKM2024.123.ØLR) has denied treaty benefits where the recipient was a conduit company without real economic activity.

Interest (Article 11)

• Domestic withholding: 22% WHT on interest paid to related parties (SEL §2, stk. 1, litra d). No WHT on interest to unrelated parties or on listed bonds (SEL §11 D exemption).
• Treaty rates: Typically 0% in most Danish treaties (e.g., UK, Germany, Netherlands, Switzerland, Luxembourg). Some older treaties have 10%. The Nordic Treaty: 0%. US Treaty: 0%. To claim the 0% rate, the recipient must be the beneficial owner and (for related-party debt) the interest must be at arm's length.
• Related-party limitation: Even under a treaty with 0%, Danish domestic law (SEL §2, stk. 1, litra d) may still impose WHT on interest to related parties unless a specific exemption applies (e.g., the SEL §11 D listed-bond exemption). The treaty overrides the domestic rate but does not eliminate the obligation to file for relief.
• Anti-abuse: Back-to-back loan arrangements structured to exploit treaty benefits are subject to Danish anti-abuse rules (SEL §2 E — hybrid mismatch rules) and the MLI PPT. Substance requirements are strictly enforced.

Royalties (Article 12)

• Domestic withholding: 22% WHT on royalties paid to related parties (SEL §2, stk. 1, litra d). No WHT on royalties to unrelated parties if the IP has no Danish business connection.
• Treaty rates: Typically 0% in most modern Danish treaties (e.g., UK, Germany, Netherlands, Switzerland, France). Some older treaties reserve 5-10% for copyright royalties on cultural works. The US Treaty: 0% for most royalties. The Nordic Treaty: 0%.
• Definition of royalties: Danish treaty practice follows the OECD MC definition: payments for copyrights, patents, trademarks, designs, know-how, and industrial/commercial/scientific equipment. Some treaties extend this to software rights. The distinction between a royalty (Article 12) and a business profit (Article 7) is critical — mischaracterisation can lead to unexpected withholding tax liability.

Capital Gains (Article 13)

• Shares: Most Danish treaties allocate taxing rights over share gains to the seller's country of residence. The exception is shares deriving >50% of value from immovable property (real estate-rich companies) — the property's country can tax the gain (Article 13(4)). This is significant for Danish real estate held through foreign companies.
• PE exit: Gains from the alienation of assets forming part of a Danish PE are taxable in Denmark under most treaties (Article 13(2)). This aligns with Danish exit tax rules (SEL §13 A-D).
• Ships and aircraft: Gains from the alienation of ships and aircraft in international traffic are taxable only in the country of effective management (Article 13(3), following the OECD MC).

Treaty Relief Procedures

• Relief at source: The preferred method. The Danish withholding agent applies the reduced treaty rate at the time of payment, provided the recipient has submitted a valid certificate of residence (attestation for skattemæssigt hjemsted) from the treaty partner's tax authority and a beneficial ownership declaration. Processing by SKAT: ~2-6 weeks for initial approval. Once approved, the reduced rate applies to all subsequent payments while the certificate remains valid (typically 1-3 years).
• Refund procedure: If the full 22% WHT was deducted, the recipient can file a refund claim with SKAT (Skattestyrelsen, International). The claim must include: Form 08.026 (Refund of Dividend/Interest/Royalty Tax), certificate of residence, supporting documents (contract, invoices, proof of withholding), and a statement of beneficial ownership. Processing time: 6-12 months. Interest on late refunds: ~3.5% annually from 3 months after the claim is filed.
• Deadlines: Claims must generally be filed within 3 years of the end of the calendar year in which the tax was withheld. Late claims are accepted only in exceptional circumstances — missing this deadline means the tax is permanently lost.
• EU interest/royalty directive: For payments between associated companies (≥25% ownership) within the EU, the Interest and Royalty Directive (2003/49/EC) provides 0% WHT without needing a treaty. The directive is implemented in Danish law as SEL §2, stk. 1, litra d, with anti-abuse provisions (substance requirements, 2-year holding period). The directive takes precedence over treaty claims for qualifying payments.
• EU Parent-Subsidiary Directive: Provides 0% WHT on dividends between associated companies (≥10% ownership, ≥12-month holding) in EU member states. Implemented in Danish law via SEL §2, stk. 1, litra c. The Danish implementation includes anti-abuse provisions (main purpose test, substance requirements).

Mutual Agreement Procedure (MAP)

• What MAP covers: Disputes arising from treaty interpretation, double taxation (economic or juridical), transfer pricing adjustments, PE profit attribution disputes, and residency conflicts. MAP is available to any person (not just companies) who is a resident of one of the treaty states.
• Danish competent authority: Skattestyrelsen, International (International Tax Office) in Copenhagen. Contact via the Danish Customs and Tax Administration's MAP unit. Response times: typically 6-12 months for initial acknowledgment, 2-4 years for full resolution.
• MAP process (Danish practice): (1) The taxpayer files a MAP request with the Danish competent authority within 3 years of the first notification of the action resulting in double taxation (if the treaty follows the OECD MC 2017 timeframe). (2) The Danish authority reviews the request and decides whether to admit it (generally admitted if the taxpayer has a prima facie case of treaty violation). (3) If admitted, the Danish authority contacts the treaty partner's competent authority to negotiate a resolution. (4) The taxpayer is informed of the outcome and can accept or reject the resolution. (5) If the resolution requires implementing a domestic adjustment, the taxpayer files the necessary returns.
• MAP statistics: Denmark resolves approximately 60-70% of MAP cases within 24 months (OECD BEPS Action 14 statistics). The average resolution time is 18-24 months for transfer pricing MAP cases and 12-18 months for residency/PE cases.
• Arbitration: Under the MLI (mandatory binding arbitration for ~50 treaties) and the EU Arbitration Convention (90/436/EEC, applicable to transfer pricing disputes within the EU), unresolved MAP cases can proceed to arbitration. The arbitration is binding on both tax authorities. The process typically takes 2-3 years from the MAP filing date.
• Interaction with domestic remedies: MAP is available alongside domestic appeals (administrative appeal to Skatteankestyrelsen and courts). However, the taxpayer cannot pursue both MAP and domestic remedies simultaneously if the result of one would be binding on the other. In practice, Danish MAP requests are often filed as a parallel track to protect the taxpayer's position while domestic remedies are exhausted.

Multilateral Instrument (MLI) Impact

• Denmark's MLI ratification: Denmark deposited its MLI instrument with the OECD on 23 January 2019, effective from 1 June 2019. ~70 Danish treaties are Covered Tax Agreements (CTAs).
• Denmark's key MLI positions:
  • Principal Purpose Test (PPT): Denmark adopted the PPT (Article 7 MLI) as the minimum standard. It applies to all covered treaties unless the other contracting state opted for the simplified LOB + PPT alternative. The PPT denies treaty benefits if obtaining them was one of the principal purposes of the arrangement, unless granting benefits would be in accordance with the treaty's object and purpose.
  • PE provisions (Article 12-15 MLI): Denmark adopted the changes to the PE definition: anti-fragmentation rule (Article 13(2)), 30-day grace period extension for construction PEs (Article 14(2)), and the revised agency PE definition (Article 12). These apply to covered treaties unless the other state opted out.
  • Mandatory binding arbitration (Article 18-26): Denmark adopted mandatory binding arbitration for MAP cases unresolved after 2 years, applying to ~50 treaties where the other state also adopted it.
  • Preambles: Denmark adopted the preamble language confirming the treaty is not intended to create opportunities for non-taxation or reduced taxation through treaty shopping.
• Practical impact: The PPT is the most significant change. Every cross-border payment structure must now satisfy the PPT — substance requirements alone may not be sufficient if the principal purpose was treaty shopping. Danish case law on the PPT is still developing (first PPT-related binding rulings issued in 2024-2025).

Notable Treaty Rates Table

Note: Rates shown are general guidelines. Always verify the specific treaty provisions, as conditions and definitions may vary. The rates apply only if the recipient is the beneficial owner and satisfies any LOB/PPT requirements. For cross-border M&A and group structuring considerations, see our Cross-Border M&A Tax Guide →. For transfer pricing implications, see our Transfer Pricing Guide →.

Beneficial Ownership and Substance Requirements

• Danish beneficial ownership concept: Denmark applies the OECD MC Commentary definition: the beneficial owner is the person who has the right to use and enjoy the dividend, interest, or royalty (not merely an intermediary, agent, or nominee). Danish courts have ruled that conduit companies with no real economic activity (employees, office space, decision-making power) cannot be beneficial owners (SKM2020.123.HR, SKM2024.45.ØLR).
• Substance requirements for holding companies: To obtain treaty benefits on outbound payments from Denmark, the recipient must have: (a) employees with relevant qualifications, (b) physical office space in the treaty country, (c) independent decision-making power over the Danish investment, (d) the ability to bear economic risk, and (e) no contractual obligation to pass the payment on to a third party. A Danish holding company used as an intermediate holding should similarly have substance to avoid SKAT recharacterisation. See our Holding Companies Guide → for intermediate holding substance requirements.
• Denmark's substance-over-form doctrine (realitetsprincip): SKAT applies the substance-over-form principle to disregard legal structures that have no economic reality. If an intermediary company is inserted solely to access a more favourable treaty, SKAT will look through it and deny treaty benefits. The Danish Supreme Court has consistently upheld this approach.
• Documentation: Maintain: organisational charts, substance documentation (employment contracts, lease agreements, board minutes showing independent decision-making), group financing agreements, and beneficial ownership declarations for each payment chain.

Key Risks and Practical Points

• Treaty shopping post-MLI: The MLI PPT applies to ~70 Danish treaties. Any structure that has treaty benefit as a principal purpose (even if there are also business reasons) risks denial of benefits. The PPT assessment is objective — the taxpayer's subjective intent is not the only factor.
• Denmark's domestic anti-abuse rules: Even if a treaty would grant relief, Danish domestic anti-abuse rules (including the substance-over-form doctrine and the specific anti-abuse rules in SEL §2 for EU directives) may deny benefits. The taxpayer must satisfy both the treaty requirements and the domestic law requirements.
• Information exchange (EOIR): Under Article 26 of most Danish treaties, SKAT can request information from the treaty partner about specific taxpayers. The exchange of information is not limited to cases where the taxpayer is under audit — it can be a proactive request based on risk indicators. Denmark is a signatory to the OECD Multilateral Convention on Mutual Administrative Assistance in Tax Matters, which provides additional exchange mechanisms beyond bilateral treaties.
• Treaty rate changes: Treaty rates are subject to renegotiation. Denmark has recently renegotiated treaties with India (2018), China (2019), and several developing countries. Check the applicable protocol and effective date before relying on a specific rate.
