Internal Revenue Bulletin 2005-21 · 2026-10-03 edition · updated 2026-10-04 · United States

.01 Section 864(e)(2) of the Internal Revenue Code provides that allocation and apportionment of interest expense is made on the basis of assets rather than on the basis of gross income. For this purpose, §§ 1.861–8T(c)(2) and 1.861–9T(g)(1)(ii) of the temporary regulations permit a taxpayer to elect to compute the value of its assets under either the tax book value method or the fair market value method. A taxpayer using the tax book value method may elect to change to the fair market value method at any time. See Rev. Proc. 2003–37, 2003–1 C.B. 950. However, § 1.861–8T(c)(2) provides that a taxpayer electing to use the fair market value method must continue to use that method unless expressly authorized by the Commissioner to change methods.

.02 On March 26, 2004, the Treasury Department and the Internal Revenue Service (IRS) published temporary regulations in the Federal Register (T.D. 9120, 2004–19 C.B. 881 [69 FR 15673]). These regulations amended §1.861–9T by adding §1.861–9T(i). Section 1.861–9T(i) provides an alternative method of determining the tax book value of assets (the “alternative tax book value method”). Prior to the issuance of the temporary regulations, a taxpayer could value assets under one of two methods: the fair market value method and the regular tax book value method. The alternative tax book value method set forth in the temporary regulations is a third method which allows a taxpayer to elect to determine the tax book value of its tangible property that is subject to a depreciation deduction under § 168 as though all such property had been depreciated using the straight line method, conventions, and recovery periods of the alternative depreciation system
