Internal Revenue Bulletin 2006-47 · 2026-10-03 edition · updated 2026-10-04 · United States
PROCEDURES
.01 APPROVAL. The consent of the Commissioner is hereby granted, provided the taxpayer complies with all the applicable provisions of this revenue procedure, to any taxpayer within the scope of this revenue procedure to change its election:
(1) INTEREST EXPENSE. From the fair market value method under § 1.861–8T(c)(2) or the alternative tax book value method under § 1.861–9(i) of apportioning interest expense to another method; or

.02 STATEMENT REQUIREMENT. (1) A corporation shall request to change an election within the scope of this revenue procedure on a Form 1118 by attaching to Form 1118 the applicable statement set forth in § 4.02(2) of this revenue procedure. In the case of such taxpayers electronically filing Form 1118, the statement must be included in the electronic version of Form 1118. A taxpayer, other than a corporation, shall request to change an election within the scope of this revenue procedure on Form 1116 by attaching to Form 1116 one of the three statements, whichever is applicable, set forth in § 4.02(2) of this revenue procedure.

section 199) for the taxable year (or, in the case of an individual, adjusted gross income (AGI)).
(2) DETERMINATION OF QPAI. To determine QPAI for a taxable year, a taxpayer must subtract from its domestic production gross receipts (DPGR) the cost of goods sold allocable to DPGR and other expenses, losses, or deductions (deductions) that are properly allocable to DPGR. Section 1.199–4(d) provides that a taxpayer generally must determine deductions allocable to DPGR, or to gross income attributable to DPGR, under the section 861 regulations.
.02 RULES FOR ALLOCATION AND APPORTIONMENT OF DEDUCTIONS.
(1) IN GENERAL. The section 861 regulations provide guidance for the allocation and apportionment of deductions in determining the taxable income of a taxpayer from specific sources and activities under sections of the Code, referred to as operative sections. Section 199 is treated as an operative section for purposes of the section 861 regulations. See § 1.199–4(d)(1).
(2) CONFORMITY OF APPLICATION. Where more than one operative section applies, the taxpayer may be required to apply the section 861 regulations separately for each applicable operative section. In that case, § 1.861–8(f)(2)(i) provides that the taxpayer is required to use the same method of allocation and the same principles of apportionment for all operative sections. See also § 1.199–4(d)(1).
.03 ALLOCATION AND APPORTIONMENT OF INTEREST EXPENSE.
(1) IN GENERAL. Taxpayers generally are required under §§ 1.861–8T(c)(2) and 1.861–9 to apportion interest expense on the basis of assets. Section 1.861–8T(c)(2) provides that the apportionment must be made either on the basis of the tax book value of the assets or on the fair market value of the assets. Section 1.861–9(i)(1) permits a taxpayer to elect to determine tax book value using the alternative tax book value method.
(2) BINDING ELECTION. Under § 1.861–8T(c)(2), once the taxpayer uses the fair market value method, the taxpayer and all related persons must continue to use that method unless expressly authorized by the Commissioner to change methods. Similarly, under
§ 1.861–9(i)(2)(i), if a taxpayer elects to use the alternative tax book value method, the taxpayer and all related persons may not, during the year of election and the four taxable years thereafter, determine tax book value under another method without the consent of the Commissioner. In Rev. Proc. 2005–28, 2005–1 C.B. 1093, the Commissioner provided automatic consent for taxpayers to change from the fair market value method to the alternative tax book value method, provided that certain requirements were met.
.04 ALLOCATION AND APPORTIONMENT OF RESEARCH AND EXPERIMENTAL EXPENDITURES.
(1) IN GENERAL. Pursuant to § 1.861–17, after allocating legally mandated R&E, if any, under § 1.861–17(a)(4) and exclusively apportioning applicable R&E, if any, under § 1.861–17(b)(1)(i), the remaining R&E of the taxpayer is apportioned under either the sales method of § 1.861–17(c) or one of the two gross income methods of § 1.861–17(d).
(2) BINDING ELECTION. Under § 1.861–17(e), a taxpayer may choose either the sales method or the optional gross income methods for the original return for its first taxable year to which § 1.861–17 applies. Once the method is elected, the taxpayer is required to use the method for that year and for the four taxable years thereafter. A taxpayer may not revoke its election of either method during the five-year period without the consent of the Commissioner.
.05 PREAMBLE OF FINAL REGULATIONS UNDER SECTION 199. The preamble to the final regulations under section 199 states that the Treasury Department and the IRS intend to issue a revenue procedure granting automatic consent to change elections under §§ 1.861–8T(c)(2) and 1.861–9(i)(1), respectively, to apportion interest expense and under § 1.861–17(e) to apportion R&E expense. Accordingly, this revenue procedure provides rules for obtaining that automatic consent.
