Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter N — Tax Based on Income From Sources Within or Without the United States › PART III — INCOME FROM SOURCES WITHOUT THE UNITED STATES › Subpart J — Foreign Currency Transactions › § 986
When you claim a foreign tax credit and you use accrual accounting, you must convert foreign income taxes and any adjustments into U.S. dollars using the average exchange rate for the taxable year those taxes relate to. That average-rate rule does not apply if the tax is paid more than 2 years after the end of that taxable year, paid before the taxable year starts, or if the tax liability is in an inflationary currency (Treasury will define those). You can choose not to use the average rate for taxes denominated in a currency other than your functional currency; that choice applies to the year you make it and future years unless Treasury allows you to revoke it. Regulated investment companies that use accrual accounting must instead convert taxes using the exchange rate on the date the income accrues. If the average-rate rule or the RIC rule does not apply, translate taxes at the exchange rate when you pay them. Translate adjustments at the rate when the adjustment is paid, except refunds or credits use the rate from the original payment. Treasury may allow using an average rate for the payment period. “Foreign income taxes” here means income, war-profits, or excess-profits taxes paid or accrued to a foreign country or to a U.S. possession. A foreign corporation’s earnings and profits are figured in its own functional currency. When a U.S. person gets those earnings (or they are treated as received), convert them to dollars using the right exchange rate. If previously taxed earnings are later distributed, any gain or loss from exchange rate changes between the deemed and actual distribution must be reported as ordinary income or loss from the same source as the original inclusion. Treasury will issue rules for multi-tiered foreign corporation distributions.
