Payments in foreign currency.
(2) Payments in foreign currency. If the amount subject to withholding tax is paid in a currency other than the U.S. dollar, the amount of withholding under section 1441 shall be determined by applying the applicable rate of withholding to the foreign currency amount and converting the amount withheld into U.S. dollars on the date of payment at the spot rate (as defined in 1.988-1(d)(1)) in effect on that date. A withholding agent making regular or frequent payments in foreign currency may use a month-end spot rate or a monthly average spot rate. In addition, such a withholding agent may use the spot rate on the date the amount of tax is deposited (within the meaning of 1.6302-2(a)), provided that such deposit is made within seven days of the date of the payment giving rise to the obligation to withhold. A spot rate convention must be used consistently for all non-dollar amounts withheld and from year to year. Such convention cannot be changed without the consent of the Commissioner. The U.S. dollar amount so determined shall be treated by the beneficial owner as the amount of tax paid on the income for purposes of determining the final U.S. tax liability and, if applicable, claiming a refund or credit of tax.
