ARTICLE 26

U.S. Income Tax Treaty — Denmark Technical Explanation - 2000 · 2026-10-03 edition · updated 2026-10-04 · United States

Exchange of Information

Paragraph 1

This Article provides for the exchange of information between the competent authorities

of the Contracting States. The information to be exchanged is that which is relevant for carrying out the provisions of the Convention or the domestic laws of the United States or of Denmark concerning the taxes covered by the Convention. The language differs from that of the OECD Model which refers to information that is "necessary" for carrying out the provisions of the Convention, etc. This term consistently has been interpreted as being equivalent to "relevant," and as not requiring a requesting State to demonstrate that it would be unable to enforce its tax laws unless it obtained a particular item of information. To remove any potentially wrong impression that the term "necessary" created a higher threshold than relevance, the U.S. Model and the Convention adopt the term "relevant."

The taxes covered by the Convention for purposes of this Article constitute a broader category of taxes than those referred to in Article 2 (Taxes Covered). As provided in paragraph 4, for purposes of exchange of information, covered taxes include all taxes imposed by the Contracting States. Exchange of information with respect to domestic law is authorized insofar as the taxation under those domestic laws is not contrary to the Convention. Thus, for example, information may be exchanged with respect to a covered tax, even if the transaction to which the information relates is a purely domestic transaction in the requesting State and, therefore, the exchange is not made for the purpose of carrying out the Convention.

An example of such a case is provided in the OECD Commentary: A company resident in the United States and a company resident in the other Contracting State transact business between themselves through a third-country resident company. Neither Contracting State has a treaty with the third State. In order to enforce their internal laws with respect to transactions of their residents with the third-country company (since there is no relevant treaty in force), the Contracting State may exchange information regarding the prices that their residents paid in their transactions with the third-country resident.

Paragraph 1 states that information exchange is not restricted by Article 1 (General Scope). Accordingly, information may be requested and provided under this Article with respect to persons who are not residents of either Contracting State. For example, if a third-country resident has a permanent establishment in Denmark which engages in transactions with a U.S. enterprise, the United States could request information with respect to that permanent establishment, even though it is not a resident of either Contracting State. Similarly, if a third-country resident maintains a bank account in Denmark, and the Internal Revenue Service has reason to believe that funds in that account should have been reported for U.S. tax purposes but have not been so reported, information can be requested from Denmark with respect to that person's account.

Paragraph 1 also provides assurances that any information exchanged will be treated as secret, subject to the same disclosure constraints as information obtained under the laws of the requesting State. Information received may be disclosed only to persons, including courts and administrative bodies, involved with the assessment, collection, enforcement or prosecution in respect of the taxes to which the information relates, or to persons involved with the administration of these taxes or with the oversight of such activities. The information must be used by these persons in connection with these designated functions. Persons in the United States involved with the oversight of the administration of taxes include legislative bodies, such as the

tax-writing committees of Congress and the General Accounting Office. Information received by these bodies must be for use in the performance of their role in overseeing the administration of U.S. tax laws. Information received may be disclosed in public court proceedings or in judicial decisions.

The Article authorizes the competent authorities to exchange information on a routine basis, on request in relation to a specific case, or spontaneously. It is contemplated that the Contracting States will utilize this authority to engage in all of these forms of information exchange, as appropriate.

Paragraph 2

Paragraph 2 provides that the obligations undertaken in paragraph 1 to exchange information do not require a Contracting State to carry out administrative measures that are at variance with the laws or administrative practice of either State. Nor is a Contracting State required to supply information not obtainable under the laws or administrative practice of either State, or to disclose trade secrets or other information, the disclosure of which would be contrary to public policy. Thus, a requesting State may be denied information from the other State if the information would be obtained pursuant to procedures or measures that are broader than those available in the requesting State.

While paragraph 2 states conditions under which a Contracting State is not obligated to comply with a request from the other Contracting State for information, the requested State is not precluded from providing such information, and may, at its discretion, do so subject to the limitations of its internal law.

Paragraph 3

Paragraph 3 sets forth two exceptions from the dispensations described in paragraph 2. First, the first sentence of the paragraph provides that the competent authority has the authority to obtain and provide information held by financial institutions or intermediaries. This includes the disclosure of information regarding the beneficial owner of an interest in a person.

Second, paragraph 3 provides that when information is requested by a Contracting State in accordance with this Article, the other Contracting State is obligated to obtain the requested information as if the tax in question were the tax of the requested State, even if the other Contracting State has no direct tax interest in the case to which the request relates. The OECD Model does not state explicitly in the Article that the requested State is obligated to respond to a request even if it does not have a direct tax interest in the information. The OECD Commentary, however, makes clear that this is to be understood as implicit in the OECD Model.

Paragraph 3 further provides that the requesting State may specify the form in which information is to be provided (e.g., depositions of witnesses and authenticated copies of original documents) so that the information is usable in the judicial proceedings of the requesting State. The requested State should, if possible, provide the information in the form requested to the same extent that it can obtain information in that form under its own laws and administrative practices

with respect to its own taxes.

Paragraph 4

As noted above in the discussion of paragraph 1, the exchange of information provisions of the Convention apply to all taxes imposed by a Contracting State, not just to those taxes designated as covered taxes under Article 2 (Taxes Covered). The U.S. competent authority may, therefore, request information for purposes of, for example, estate and gift taxes or federal excise taxes.

Treaty Effective Dates and Termination in Relation to Information Exchange

A tax administration may seek information with respect to a year for which a treaty was in force after the treaty has been terminated. In such a case the ability of the other tax administration to act is limited. The treaty no longer provides authority for the tax administrations to exchange confidential information. They may only exchange information pursuant to domestic law.

The competent authority also may seek information under the Convention, but with respect to a year in which the prior Convention was in force. The scope of the competent authorities to address such a case is not constrained by the fact that the prior Convention was in force when the transactions at issue occurred, and the competent authorities have available to them the full range of information exchange provisions afforded under this Article to the extent they exceed those under the prior Convention.
