Sec. 1.985-4 Method of Accounting.



Adoption of election.

     The adoption of, or the election to use, a functional currency shall be treated as a method of accounting. The functional currency shall be used for the year of adoption (or election) and for all subsequent taxable years unless permission to change is granted, or considered to be granted under section 1.985-2 or 1.985-8 by the Commissioner.

(b) Condition for changing functional currencies.

     Generally, permission to change functional currencies shall not be granted unless significant changes in the facts and circumstances of the QBU's economic environment occur. If the determination of the functional currency of the QBU for purposes of United States generally accepted accounting principles (GAAP) is based on facts and circumstances substantially similar to those set forth in section 1.985-1(c)(2), then ordinarily the Commissioner will grant a taxpayer's request to change its functional currency (or the functional currency of its branch that is a QBU) to a new functional currency only if the taxpayer (or its QBU) also changes to the new functional currency for purposes of GAAP. However, permission to change will not necessarily be granted merely because the new functional currency will conform to the taxpayer's GAAP functional currency.

(c) Relationship to certain other sections of the Code.

     Nothing in this section shall be construed to override the provisions of any other sections of the Code of regulations that require the use of consistent accounting methods. Such provisions must be independently satisfied separate and apart from the identification of a functional currency. For instance, while separate geographical divisions of a taxpayer's trade or business may have different functional currencies, such geographical divisions may nevertheless be required to consistently use other methods of accounting.
