ARTICLE 26

U.S. Income Tax Treaty — Italy Technical Explanation - 1984 · 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 necessary for carrying out the provisions of the Convention or the domestic laws of the United States or of Italy concerning the taxes covered by the Convention. The reference to information that is “necessary” is consistent with the OECD Model, and while the U.S. Model refers to information that is “relevant”, the terms consistently have been interpreted as being equivalent, 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. Therefore, it should not be interpreted that “necessary” creates a higher threshold than “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 20 of Article 1 of the Protocol, 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 Italy 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 thirdcountry company (since there is no relevant treaty in force), the Contracting States 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 (Personal 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 Italy 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 Italy, 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 Italy 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 or collection of, enforcement or prosecution in respect of, or the determination of appeals in relation to, the taxes to which the information relates. Paragraph 20 of Article 1 of the Protocol provides that information may also be disclosed to persons or authorities involved in 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 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 is identical to paragraph 2 of Article 26 of the OECD Model. It 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.

The Convention does not contain a paragraph corresponding to paragraph 3 of the Model, which sets forth certain exceptions from the dispensations described in paragraph 2. One such exception contained in the U.S. Model 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 that State has no direct tax interest in the case to which the request relates. The OECD Mode, like the Convention, 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. (See paragraph 16 of the OECD Commentary to Article 26.) Thus, it is implicit in the Convention.

The Convention also does not contain the first sentence of paragraph 3 of the Model, which provides that information must be provided to the requesting State notwithstanding the fact that disclosure of the information is precluded by bank secrecy or similar legislation relating to disclosure of financial information by financial institutions or intermediaries. The United States has received assurances from the Italian Ministry of Finance concerning Italy’s ability to exchange third-party information obtained from banks and other financial institutions. Given these assurances, and the longstanding relationship with Italy regarding exchange of information under the prior Convention, the Treasury Department believes that the omission of the sentence will not affect the United States’ ability to obtain this third-party information from Italy.
