IRS Simplifies Change to Alternate Book Value Method

A newly issued revenue procedure, Rev. Proc. 2005-28, makes it easier for some taxpayers to adopt a simpler method of allocating and apportioning interest expenses in determining their net U.S. and foreign-source income for foreign tax credit purposes.

Taxpayers generally may elect to measure assets for purposes of apportioning interest expense between U.S. and foreign sources under the tax book value method or the fair market value method. Temporary and proposed regulations issued in March 2004 provide taxpayers with an elective alternative approach, the alternative tax book value method, which permits a taxpayer to determine the basis of its U.S. and foreign assets for interest allocation purposes without incurring the disparities that may arise under the regular tax book value method.
