ARTICLE 18
U.S. Income Tax Treaty — Denmark Technical Explanation - 2000 · 2026-10-03 edition · updated 2026-10-04 · United States
Pensions, Social Security, Annuities, Alimony and Child Support Payments
This Article deals with the taxation of private (i.e., non-government service) pensions and annuities, social security benefits, alimony and child support payments.
Paragraph 1
Subparagraph 1(a) provides that, except as provided in subparagraph (b), distributions from pensions and other similar remuneration beneficially owned by a resident of a Contracting State in consideration of past employment are taxable only in the State in which they arise. Paragraph 4 of the Protocol defines a payment that is treated as a pension distribution under paragraph 1. Paragraph 4(a) provides that a payment shall be treated as a pension distribution for this purpose if it is a payment under a pension scheme recognized for tax purposes in the Contracting State where the pension scheme is established. Paragraph 4(b) provides that, for this purpose, pension schemes recognized for tax purposes shall include the schemes listed under clause (i) in the case of the United States and under clause (ii) in the case of Denmark. With reference to U.S. Law, clause (i) lists qualified plans under section 401(a), individual retirement plans (including individual retirement plans that are part of a simplified employee pension plan that satisfies section 408(k), individual retirement accounts, individual retirement annuities, section 408(p) accounts and Roth IRAs under section 408A), section 403(a) qualified plans, and section 403(b) plans. With reference to Danish law, clause (ii) lists pension schemes under Section I of the Act on Taxation of Pension Schemes ( pensionsbeskatningslovens afsnit I ). Subparagraph 1(d) makes explicit the fact that the term "pension distributions and other similar remuneration" includes both periodic and lump sum payments.
Under the prior Convention, distributions were taxable only in the country of residence. Since many retirees may have relied on the old rule when deciding to move from one Contracting State to another, subparagraph 1(b) provides a grandfather rule to prevent the tax burden of such retirees from being suddenly increased. This rule states that, if prior to the time of entry into force of this Convention, a person was a resident of a Contracting State and was receiving pension distributions arising in the other Contracting State, that person shall be taxable on pension distributions referred to in subparagraph (a) only in the first-mentioned State. Thus, subparagraph (b) provides for taxation only in the residence State, rather than taxation only in the source State, in the case of a pension distribution received by a citizen of one Contracting State who, before this Convention enters into force, is receiving a pension distribution arising in the other Contracting State.
Subparagraph 1(c) provides a rule for administrative convenience under which pension distributions shall be deemed to arise in a Contracting State only if paid by a pension scheme established in that State. This rule eliminates the necessity of dividing pension distributions between different countries on the basis of services performed in the various countries.
Paragraph 2
The treatment of social security benefits is dealt with in paragraph 2. This paragraph provides that, notwithstanding the provision of paragraph 1, payments made by one of the Contracting States under the provisions of its social security or similar legislation to a resident of the other Contracting State or to a citizen of the United States will be taxable only in the Contracting State making the payment. This paragraph applies to social security beneficiaries whether they have contributed to the system as private sector or Government employees.
The phrase "similar legislation" is intended to refer to United States tier 1 Railroad Retirement benefits. The reference to U.S. citizens is necessary to ensure that a social security
payment by Denmark to a U.S. citizen who is not resident in the United States will not be taxable by the United States.
Paragraph 3
Under paragraph 3, annuities that are derived and beneficially owned by an individual resident of a Contracting State are taxable only in that State. An annuity, as the term is used in this paragraph, means a stated sum paid periodically at stated times during a specified number of years, or for life, under an obligation to make the payment in return for adequate and full consideration (other than for services rendered). An annuity received in consideration for services rendered would be treated as deferred compensation and generally taxable in accordance with Article 15 (Dependent Personal Services).
Paragraphs 4 and 5
Paragraphs 4 and 5 deal with alimony and child support payments, respectively. Alimony and child support payments are defined as periodic payments made pursuant to a written separation agreement or a decree of divorce, separate maintenance, or compulsory support. Paragraph 4, however, deals only with payments of that type that are deductible to the payor and taxable to the payee. Under that paragraph, alimony (i.e., a deductible payment that is taxable in the hands of the recipient) paid by a resident of a Contracting State to a resident of the other Contracting State is taxable under the Convention only in the State of residence of the recipient. Paragraph 5 deals with those periodic payments that are for the support of a child and that are not covered by paragraph 4 (i.e., those payments that either are not deductible to the payor or not taxable to the payee). These types of payments by a resident of a Contracting State to a resident of the other Contracting State shall be taxable only in the first-mentioned Contracting State.
Relationship to Other Articles
Paragraphs 3 and 4 of Article 18 are subject to the saving clause of paragraph 4 of Article 1 (General Scope). Thus, a U.S. citizen who is resident in Denmark, and receives either an annuity or alimony payment from the United States, may be subject to U.S. tax on the payment, notwithstanding the rules in those two paragraphs that give the State of residence of the recipient the exclusive taxing right. Paragraph 1, with the exception of subparagraph (c), also is subject to the saving clause. Therefore, a U.S. citizen who is resident in Denmark, and receives a pension payment from a pension scheme established in Denmark may be subject to U.S. tax on the payment, but the United States will treat that payment as arising in Denmark for foreign tax credit purposes. Paragraphs 2 and 5 are excepted from the saving clause by virtue of paragraph 5(a) of Article 1. Thus, the United States will allow U.S. citizens and residents the benefits of paragraph 2 and 5.
