1.861-8—Computation of taxable income from sources within the United States and from other sources and activities.

(a) In general— (1) Scope. Sections 861(b) and 863(a) state in general terms how to determine taxable income of a taxpayer from sources within the United States after gross income from sources within the United States has been determined. Sections 862(b) and 863(a) state in general terms how to determine taxable income of a taxpayer from sources without the United States after gross income from sources without the United States has been determined. This section provides specific guidance for applying the cited Code sections by prescribing rules for the allocation and apportionment of expenses, losses, and other deductions (referred to collectively in this section as “deductions”) of the taxpayer. The rules contained in this section apply in determining taxable income of the taxpayer from specific sources and activities under other sections of the Code, referred to in this section as operative sections. See paragraph (f)(1) of this section for a list and description of operative sections. The operative sections include, among others, sections 871(b) and 882 (relating to taxable income of a nonresident alien individual or a foreign corporation which is effectively connected with the conduct of a trade or business in the United States), section 904(a)(1) (as in effect before enactment of the Tax Reform Act of 1976, relating to taxable income from sources within specific foreign countries), and section 904(a)(2) (as in effect before enactment of the Tax Reform Act of 1976, or section 904(a) after such enactment, relating to taxable income from all sources without the United States).
(2) Allocation and apportionment of deductions in general. A taxpayer to which this section applies is required to allocate deductions to a class of gross income and, then, if necessary to make the determination required by the operative section of the Code, to apportion deductions within the class of gross income between the statutory grouping of gross income (or among the statutory groupings) and the residual grouping of gross income. Except for deductions, if any, which are not definitely related to gross income (see paragraphs (c)(3) and (e)(9) of this section) and which, therefore, are ratably apportioned to all gross income, all deductions of the taxpayer (except the deductions for personal exemptions enumerated in paragraph (e)(11) of this section) must be so allocated and apportioned. As further detailed below, allocations and apportionments are made on the basis of the factual relationship of deductions to gross income.
(3) Class of gross income. For purposes of this section, the gross income to which a specific deduction is definitely related is referred to as a “class of gross income” and may consist of one or more items (or subdivisions of these items) of gross income enumerated in section 61, namely:
(i) Compensation for services, including fees, commissions, and similar items;
(ii) Gross income derived from business;
(iii) Gains derived from dealings in property;
(iv) Interest;
(v) Rents;
(vi) Royalties;
(vii) Dividends;
(viii) Alimony and separate maintenance payments;
(ix) Annuities;
(x) Income from life insurance and endowment contracts;
(xi) Pensions;
(xii) Income from discharge of indebtedness;
(xiii) Distributive share of partnership gross income;
(xiv) Income in respect of a decedent;
(xv) Income from an interest in an estate or trust.
(4) Statutory grouping of gross income and residual grouping of gross income. For purposes of this section, the term “statutory grouping of gross income” or “statutory grouping” means the gross income from a specific source or activity which must first be determined in order to arrive at “taxable income” from which specific source or activity under an operative section. (See paragraph (f)(1) of this section.) Gross income from other sources or activities is referred to as the “residual grouping of gross income” or “residual grouping.” For example, for purposes of determining taxable income from sources within specific foreign countries and possessions of the United States, in order to apply the per-country limitation to the foreign tax credit (as in effect before enactment of the Tax Reform Act of 1976), the statutory groupings are the separate gross incomes from sources within each country and possession. Moreover, if the taxpayer has income subject to section 904(d) (as in effect after enactment of the Tax Reform Act of 1976), such income constitutes one or more separate statutory groupings. In the case of the per-country limitation, the residual grouping is the aggregate of gross income from sources within the United States. In some instances, where the operative section so requires, the statutory grouping or the residual grouping may include, or consist entirely of, excluded income. See paragraph (d)(2) of this section with respect to the allocation and apportionment of deductions to excluded income.
(5) Effective date— (i) Taxable years beginning after December 31, 1976. The provisions of this section apply to taxable years beginning after December 31, 1976.
(ii) Paragraph (e)(4), the last sentence of paragraph (f)(4)(i), and paragraph (g), Examples 17, 18, and 30 of this section are generally applicable for taxable years beginning after July 31, 2009. In addition, a person may elect to apply the provisions of paragraph (e)(4) of this section to earlier years. Such election shall be made in accordance with the rules set forth in § 1.482-9(n)(2).
(iii) Taxable years beginning before January 1, 1977. For taxable years beginning before January 1, 1977, § 1.861-8 applies as in effect on October 23, 1957 (T.D. 6258), as amended on August 22, 1966 (T.D. 6892) and on September 29, 1975 (T.D. 7378). The specific rules for allocation and apportionment of deductions set forth in this section may, at the option of the taxpayer, apply to those taxable years on a deduction-by-deduction basis if the rules are applied consistently to all taxable years with respect to which action by the Internal Revenue Service is not barred by any statute of limitations. Thus, for example, a calendar year taxpayer may choose to have the rules of paragraph (e)(2) of this section apply for the allocation and apportionment of all interest expenses for the two taxable years ending December 31, 1975 and 1976, which are open years under examination, and may justify the allocation and apportionment of all research and development expenses for those years on a basis supportable under § 1.861-8 as in effect for 1975 and 1976 without regard to the rules of paragraph (e)(3) of this section.
(b) Allocation— (1) In general. For purposes of this section, the gross income to which a specific deduction is definitely related is referred to as a “class of gross income” and may consist of one or more items of gross income. The rules emphasize the factual relationship between the deduction and a class of gross income. See paragraph (d)(1) of this section which provides that in a taxable year there may be no item of gross income in a class or less gross income than deductions allocated to the class, and paragraph (d)(2) of this section which provides that a class of gross income may include excluded income. Allocation is accomplished by determining, with respect to each deduction, the class of gross income to which the deduction is definitely related and then allocating the deduction to such class of gross income (without regard to the taxpayable year in which such gross income is received or accrued or is expected to be received or accrued). The classes of gross income are not predetermined but must be determined on the basis of the deductions to be allocated. Although most deductions will be definitely related to some class of a taxpayer's total gross income, some deductions are related to all gross income. In addition, some deductions are treated as not definitely related to any gross income and are ratably apportioned to all gross income. (See paragraph (e)(9) of this section.) In allocating deductions it is not necessary to differentiate between deductions related to one item of gross income and deductions related to another item of gross income where both items of gross income are exclusively within the same statutory grouping or exclusively within the residual grouping.
(2) Relationship to activity or property. A deduction shall be considered definitely related to a class of gross income and therefore allocable to such class if it is incurred as a result of, or incident to, an activity or in connection with property from which such class of gross income is derived. Where a deduction is incurred as a result of, or incident to, an activity or in connection with property, which activity or property generates, has generated, or could reasonably have been expected to generate gross income, such deduction shall be considered definitely related to such gross income as a class whether or not there is any item of gross income in such class which is received or accrued during the taxable year and whether or not the amount of deductions exceeds the amount of the gross income in such class. See paragraph (d)(1) of this section and example 17 of paragraph (g) of this section with respect to cases in which there is an excess of deductions. In some cases, it will be found that this subparagraph can most readily be applied by determining, with respect to a deduction, the categories of gross income to which it is not related and concluding that it is definitely related to a class consisting of all other gross income.
(3) Supportive functions. Deductions which are supportive in nature (such as overhead, general and administrative, and supervisory expenses) may relate to other deductions which can more readily be allocated to gross income. In such instance, such supportive deductions may be allocated and apportioned along with the deductions to which they relate. On the other hand, it would be equally acceptable to attribute supportive deductions on some reasonable basis directly to activities or property which generate, have generated or could reasonably be expected to generate gross income. This would ordinarily be accomplished by allocating the supportive expenses to all gross income or to another broad class of gross income and apportioning the expenses in accordance with paragraph (c)(1) of this section. For this purpose, reasonable departmental overhead rates may be utilized. For examples of the application of the principles of this paragraph (b)(3) to expenses other than expenses attributable to stewardship activities, see Examples 19 through 21 of paragraph (g) of this section. See paragraph (e)(4)(ii) of this section for the allocation and apportionment of deductions attributable to stewardship expenses. However, supportive deductions that are described in § 1.861-14T(e)(3) shall be allocated and apportioned in accordance with the rules of § 1.861-14T and shall not be allocated and apportioned by reference only to the gross income of a single member of an affiliated group of corporations as defined in § 1.861-14T(d).
(4) Deductions related to a class of gross income. See paragraph (e) of this section for rules relating to the allocation and apportionment of certain specific deductions definitely related to a class of gross income. See paragraph (c)(1) of this section for rules relating to the apportionment of deductions.
(5) Deductions related to all gross income. If a deduction does not bear a definite relationship to a class of gross income constituting less than all of gross income, it shall ordinarily be treated as definitely related and allocable to all of the taxpayer's gross income except where provided to the contrary under paragraph (e) of this section. Paragraph (e)(9) of this section lists various deductions which generally are not definitely related to any gross income and are ratably apportioned to all gross income.
(c) Apportionment of deductions— (1) Deductions definitely related to a class of gross income. [Reserved]. For guidance, see § 1.861-8T(c)(1).
(2) Apportionment based on assets. [Reserved]. For guidance, see § 1.861-8T(c)(2).
(3) Deductions not definitely related to any gross income. If a deduction is not definitely related to any gross income (see paragraph (e)(9) of this section), the deduction must be apportioned ratably between the statutory grouping (or among the statutory groupings) of gross income and the residual grouping. Thus, the amount apportioned to each statutory grouping shall be equal to the same proportion of the deduction which the amount of gross income in the statutory grouping bears to the total amount of gross income. The amount apportioned to the residual grouping shall be equal to the same proportion of the deduction which the amount of the gross income in the residual grouping bears to the total amount of gross income.
(d) Excess of deductions and excluded and eliminated income— (1) Excess of deductions. Each deduction which bears a definite relationship to a class of gross income shall be allocated to that class in accordance with paragraph (b)(1) of this section even though, for the taxable year, no gross income in such class is received or accrued or the amount of the deduction exceeds the amount of such class of gross income. In apportioning deductions, it may be that, for the taxable year, there is no gross income in the statutory grouping (or residual grouping), or that deductions exceed the amount of gross income in the statutory grouping (or residual grouping). If there is no gross income in a statutory grouping or the amount of deductions allocated and apportioned to a statutory grouping exceeds the amount of gross income in the statutory grouping, the effects are determined under the operative section. If the taxpayer is a member of a group filing a consolidated return, such excess of deductions allocated or apportioned to a statutory grouping of income of such member is taken into account in determining the consolidated taxable income from such statutory grouping, and such excess of deductions allocated or apportioned to the residual grouping of income is taken into account in determining the consolidated taxable income from the residual grouping. See § 1.1502-4(d)(1) and the last sentence of § 1.1502-12. For an illustration of the principles of this paragraph (d)(1), see example 17 of paragraph (g) of this section.
(2) Allocation and apportionment to exempt, excluded, or eliminated income. [Reserved]. For guidance, see § 1.861-8T(d)(2).
(e) Allocation and apportionment of certain deductions— (1) In general. Paragraphs (e)(2) and (e)(3) of this section contain rules with respect to the allocation and apportionment of interest expense and research and development expenditures, respectively. Paragraphs (e)(4) through (e)(8) of this section contain rules with respect to the allocation of certain other deductions. Paragraph (e)(9) of this section lists those deductions which are ordinarily considered as not being definitely related to any class of gross income. Paragraph (e)(10) of this section lists special deductions of corporations which must be allocated and apportioned. Paragraph (e)(11) of this section lists personal exemptions which are neither allocated nor apportioned. Paragraph (e)(12) of this section contains rules with respect to the allocation and apportionment of deductions for charitable contributions. Examples of allocation and apportionment are contained in paragraph (g) of this section.
(2) Interest. [Reserved]. For guidance, see § 1.861-8T(e)(2).
(3) Research and experimental expenditures. For rules regarding the allocation and apportionment of research and experimental expenditures, see § 1.861-17.
(4) Stewardship and controlled services— (i) Expenses attributable to controlled services. If a corporation performs a controlled services transaction (as defined in § 1.482-9(l)(3) ), which includes any activity by one member of a group of controlled taxpayers that results in a benefit to a related corporation, and the rendering corporation charges the related corporation for such services, section 482 and these regulations provide for an allocation where the charge is not consistent with an arm's length result as determined. The deductions for expenses of the corporation attributable to the controlled services transaction are considered definitely related to the amounts so charged and are to be allocated to such amounts.
(ii) Stewardship expenses attributable to dividends received. Stewardship expenses, which result from “overseeing” functions undertaken for a corporation's own benefit as an investor in a related corporation, shall be considered definitely related and allocable to dividends received, or to be received, from the related corporation. For purposes of this section, stewardship expenses of a corporation are those expenses resulting from “duplicative activities” (as defined in § 1.482-9(l)(3)(iii)) or “shareholder activities” (as defined in § 1.482-9(l)(3)(iv)) of the corporation with respect to the related corporation. Thus, for example, stewardship expenses include expenses of an activity the sole effect of which is either to protect the corporation's capital investment in the related corporation or to facilitate compliance by the corporation with reporting, legal, or regulatory requirements applicable specifically to the corporation, or both. If a corporation has a foreign or international department which exercises overseeing functions with respect to related foreign corporations and, in addition, the department performs other functions that generate other foreign-source income (such as fees for services rendered outside of the United States for the benefit of foreign related corporations, foreign-source royalties, and gross income of foreign branches), some part of the deductions with respect to that department are considered definitely related to the other foreign-source income. In some instances, the operations of a foreign or international department will also generate United States source income (such as fees for services performed in the United States). Permissible methods of apportionment with respect to stewardship expenses include comparisons of time spent by employees weighted to take into account differences in compensation, or comparisons of each related corporation's gross receipts, gross income, or unit sales volume, assuming that stewardship activities are not substantially disproportionate to such factors. See paragraph (f)(5) of this section for the type of verification that may be required in this respect. See § 1.482-9(l)(5) for examples that illustrate the principles of § 1.482-9(l)(3). See Example 17 and Example 18 of paragraph (g) of this section for the allocation and apportionment of stewardship expenses. See paragraph (b)(3) of this section for the allocation and apportionment of deductions attributable to supportive functions other than stewardship expenses, such as expenses in the nature of day-to-day management, and paragraph (e)(5) of this section generally for the allocation and apportionment of deductions attributable to legal and accounting fees and expenses.
(5) Legal and accounting fees and expenses. Fees and other expenses for legal and accounting services are ordinarily definitely related and allocable to specific classes of gross income or to all the taxpayer's gross income, depending on the nature of the services rendered (and are apportioned as provided in paragraph (c)(1) of this section). For example, accounting fees for the preparation of a study of the costs involved in manufacturing a specific product will ordinarily be definitely related to the class of gross income derived from (or which could reasonably have been expected to be derived from) that specific product. The taxpayer is not relieved from his responsibility to make a proper allocation and apportionment of fees on the grounds that the statement of services rendered does not identify the services performed beyond a generalized designation such as “professional,” or does not provide any type of allocation, or does not properly allocate the fees involved.
(6) Income taxes— (i) In general. The deduction for state, local, and foreign income, war profits and excess profits taxes (“state income taxes”) allowed by section 164 shall be considered definitely related and allocable to the gross income with respect to which such state income taxes are imposed. For example, if a domestic corporation is subject to state income taxation and the state income tax is imposed in part on an amount of foreign source income, then that part of the taxpayer's deduction for state income tax that is attributable to foreign source income is definitely related and allocable to foreign source income. In allocating and apportioning the deduction for state income tax for purposes including (but not limited to) the computation of the foreign tax credit limitation under section 904 of the Code and the consolidated foreign tax credit under § 1.1502-4 of the regulations, the income upon which the state income tax is imposed is determined by reference to the law of the jurisdiction imposing the tax. Thus, if a state attributes taxable income to a corporate taxpayer by applying an apportionment formula that takes into consideration the income and factors of one or more corporations related by ownership to the corporate taxpayer and engaging in activities related to the business of the corporate taxpayer, then the income so attributed is the income upon which the state income tax is imposed. If the income so attributed to the corporate taxpayer includes foreign source income, then, in computing the taxpayer's foreign tax credit limitation under section 904, for example, the taxpayer's deduction for state income tax will be considered definitely related and allocable to a class of gross income that includes the statutory grouping of foreign source income. When the law of the state includes dividends that are treated under section 862(a)(2) as income from sources without the United States in taxable income apportionable to the state, but does not include factors of the corporation paying such dividends in the apportionment formula used to determine state taxable income, an appropriate portion of the deduction for state income tax will be considered definitely related and allocable to a class of gross income consisting solely of foreign source dividend income. A deduction for state income tax will not be considered definitely related to a hypothetical amount of income calculated under federal tax principles when the jurisdiction imposing the tax computes taxable income under different principles. A corporate taxpayer's deduction for a state franchise tax that is computed on the basis of income attributable to business activities conducted within the state must be allocated and apportioned in the same manner as the deduction for state income taxes. In determining, for example, both the foreign tax credit under section 904 of the Code and the consolidated foreign tax credit limitation under § 1.1502-4 of the regulations, the deduction for state income tax may be allocable and apportionable to foreign source income in a statutory grouping described in section 904(d) in a taxable year in which the taxpayer has no foreign source income in such statutory grouping. Alternatively, such an allocation or apportionment may be appropriate if a taxpayer corporation has no foreign source income in a statutory grouping, but its deduction is attributable to foreign source income in such grouping that is attributed to the taxpayer corporation under the law of a state which attributes taxable income to a corporation by applying an apportionment formula that takes into consideration the income and factors of one or more corporations related by ownership to the taxpayer corporation and engaging in activities related to the business of the taxpayer corporation. Example 30 of paragraph (g) of this section illustrates the application of this last rule.
(ii) Methods of allocation and apportionment— (A) In general. A taxpayer's deduction for a state income tax is to be allocated (and then apportioned, if necessary, subject to the rules of § 1.861-8(d)) by reference to the taxable income that the law of the taxing jurisdiction attributes to the taxpayer (“state taxable income”).
(B) Effect of subsequent recomputations of state income tax. [Reserved]
(C) Illustrations— (1) In general. Examples 25 through 32 of paragraph (g) of § 1.861-8 illustrate, in the given factual situations, the application of this paragraph (e)(6) and the general rule of paragraph (b)(1) of this section that a deduction must be allocated to the class of gross income to which the deduction is factually related. In general, these examples employ a presumption that state income taxes are allocable to a class of gross income that includes the statutory grouping of income from sources without the United States when the total amount of taxable income determined under state law exceeds the amount of taxable income determined under the Code (without taking into account the deduction for state income taxes) in the residual grouping of income from sources within the United States. A taxpayer that allocates and apportions the deduction for state income tax in accordance with the methodology of Example 25 of paragraph (g) of this section must also apply the modifications illustrated in Examples 26 and 27 of paragraph (g) of this section, when applicable. The modification illustrated in Example 26 is applicable when the deduction for state income tax is attributable in part to taxes imposed by a state which factually excludes foreign source income (as determined for federal income tax purposes) from state taxable income. The modification illustrated in Example 27 is applicable when the taxpayer has income-producing activities in a state which does not impose a corporate income tax. The specific allocation of state income tax illustrated in Example 28 follows the rule in paragraph (e)(6)(i) of this section, and must be applied whenever a taxpayer's state taxable income includes dividends apportioned to the state under a formula that does not take into account the factors of the corporations paying those dividends, regardless of whether the taxpayer uses the methodology of Example 25 with respect to the remainder of the deduction for state income taxes.
(2) Modifications. Before applying a method of allocation and apportionment illustrated in the examples, the computation of state taxable income under state law may be modified, subject to the approval of the District Director, to reflect more accurately the income with respect to which the state income tax is imposed. Any modification to the state law computation of state taxable income must yield an allocation and apportionment of the deduction for state income taxes that is consistent with the rules contained in this paragraph (e)(6), and that accurately reflects the factual relationship between the state income tax and the income on which that tax is imposed. For example, a modification to the computation of taxable income under state law might be appropriate to compensate for differences between the state law definition of taxable income and the federal definition of taxable income, due to a difference in the rate of allowable depreciation or the amount of another deduction that is allowable under both systems. This rule is illustrated in Example 31 of paragraph (g) of this section. However, a modification to the computation of taxable income under state law will not be appropriate, and will not more accurately reflect the factual relationship between the state tax and the income on which the tax is imposed, to the extent such modification reflects the fact that the state does not follow federal tax principles in attributing income to the taxpayer's activities in the state. This rule is illustrated in Example 32 of paragraph (g) of this section. A taxpayer may not modify the methods illustrated in the examples, or use an alternative method of allocation and apportionment of the deduction for state income taxes, if the modification or alternative method would be inconsistent with the rules of paragraph (e)(6)(i) of this section. A taxpayer that uses a method of allocation and apportionment other than one illustrated in Example 25 (as modified by Examples 26 and 27), or 29 with respect to a factual situation similar to those of the examples, must describe the alternative method on an attachment to its federal income tax return and establish to the satisfaction of the District Director, upon examination, that the result of the alternative method more accurately reflects the factual relationship between the state income tax and the income on which the tax is imposed.
(D) Elective safe harbor methods— (1) In general. In lieu of applying the rules set forth in paragraphs (e)(6)(ii) (A) through (C) of this section, a taxpayer may elect to allocate and apportion the deduction for state income tax in accordance with one of the two safe harbor methods described in paragraph (e)(6)(ii)(D) (2) and (3) of this section. A taxpayer shall make this election for a taxable year by filing a timely tax return for that year that reflects an allocation and apportionment of the deduction for state income tax under one of the safe harbor methods and attaching to such return a statement that the taxpayer has elected to use the safe harbor method provided in either paragraph (e)(6)(ii)(D) (2) or (3) of this section, as appropriate. Once made, this election is effective for the taxable year for which made and all subsequent taxable years, and may be revoked only with the consent of the Commissioner. Example 33 of paragraph (g) of this section illustrates the application of these safe harbor methods.
(2) Method One —(i) Step One—Specific allocation to foreign source portfolio dividends and other income. If any portion of the deduction for state income tax is attributable to tax imposed by a state which includes in a corporate taxpayer's taxable income apportionable to the state, portfolio dividends (as defined in paragraph (i) of Example 28 of paragraph (g) of this section) that are treated under section 862(a)(2) as income from sources without the United States, but does not include factors of the corporations paying the portfolio dividends in the apportionment formula used to determine state taxable income, the taxpayer shall allocate an appropriate portion of the deduction to a class of gross income consisting solely of foreign source portfolio dividends. The portion of the deduction so allocated, and the amount of foreign source portfolio dividends included in such class, shall be determined in accordance with the methodology illustrated in paragraph (ii) of Example 28 of paragraph (g). If a state income tax is determined based upon formulary apportionment of the total taxable income attributable to the taxpayer's unitary business, the taxpayer must also apply the methodology illustrated in paragraph (ii) (C) through (G) of Example 29 of paragraph (g) of this section to make specific allocations of appropriate portions of the deduction for state income tax on the basis of income that, under separate accounting, would have been attributed to other members of the unitary group. The taxpayer shall reduce its aggregate state taxable income by the amount of foreign source portfolio dividends and other income to which a specific allocation is made (the reduced amount being referred to hereinafter as “adjusted state taxable income”).
(ii) Step Two—Adjustment of U.S. source federal taxable income. If the taxpayer has significant income-producing activities in a state which does not impose a corporate income tax or other state tax measured by income derived from business activities in the state, the taxpayer shall reduce its U.S. source federal taxable income (solely for purposes of this safe harbor method) by the amount of federal taxable income attributable to its activities in such state. This amount shall be determined in accordance with the methodology illustrated in paragraph (ii) of Example 27 of paragraph (g) of this section, provided that the taxpayer shall be required to use the rules of the Uniform Division of Income for Tax Purposes Act to attribute income to the relevant state. The taxpayer's U.S. source federal taxable income, as so reduced, is referred to hereinafter as “adjusted U.S. source federal taxable income.”
(iii) Step Three—Allocation. The taxpayer shall allocate the remainder of the deduction for state income tax (after reduction by the portion allocated to foreign source portfolio dividends and other income under Step One) in accordance with the methodology illustrated in paragraph (ii) of Example 25 of paragraph (g) of this section. However, the taxpayer shall substitute for the comparison of aggregate state taxable income to U.S. source federal taxable income, illustrated in paragraph (ii) of Example 25 of paragraph (g) of this section, a comparison of its adjusted state taxable income to an amount equal to 110% of its adjusted U.S. source federal taxable income.
(iv) Step Four—Apportionment. In the event that apportionment of the remainder of the deduction for state income tax is required, the taxpayer shall apportion that remaining deduction to U.S. source income in accordance with the methodology illustrated in paragraph (iii) of Example 25 of paragraph (g) of this section, substituting for domestic source income in that paragraph an amount equal to 110% of the taxpayer's adjusted U.S. source federal taxable income. The remaining portion of the deduction shall be apportioned to the statutory groupings of foreign source income described in section 904(d) of the Code in accordance with the proportion of the income in each statutory grouping of foreign source income described in section 904(d) to the taxpayer's total foreign source federal taxable income (after reduction by the amount of foreign source portfolio dividends to which tax has been specifically allocated under Step One, above).
(3) Method Two —(i) Step One—Specific allocation to foreign source portfolio dividends and other income. Step One of this method is the same as Step One of Method One (as described in paragraph (e)(6)(ii)(D)(2 )(i) of this section).
(ii) Step Two—Adjustment of U.S. source federal taxable income. Step Two of this method is the same as Step Two of Method One (as described in paragraph (e)(6)(ii)(D)(2 )(ii) of this section).
(iii) Step Three—Allocation. The taxpayer shall allocate the remainder of the deduction for state income tax (after reduction by the portion allocated to foreign source portfolio dividends and other income under Step One) in accordance with the methodology illustrated in paragraph (ii) of Example 25 of paragraph (g) of this section. However, the taxpayer shall substitute for the comparison of aggregate state taxable income to U.S. source federal taxable income, illustrated in paragraph (ii) of Example 25 of paragraph (g) of this section, a comparison of its adjusted state taxable income to its adjusted U.S. source federal taxable income.
(iv) Step Four—Apportionment. In the event that apportionment of the deduction is required, the taxpayer shall apportion to U.S. source income that portion of the deduction that is attributable to state income taxes imposed upon an amount of state taxable income equal to adjusted U.S. source federal taxable income. The taxpayer shall apportion the remaining amount of the deduction to U.S. and foreign source income in the same proportions that the taxpayer's adjusted U.S. source federal taxable income and foreign source federal taxable income (after reduction by the amount of foreign source portfolio dividends to which tax has been specifically allocated under Step One, above) bear to its total federal taxable income (taking into account the adjustment of U.S. source federal taxable income under Step Two and after reduction by the amount of foreign source portfolio dividends to which tax has been specifically allocated under Step One). The portion of the deduction apportioned to foreign source income shall be apportioned among the statutory groupings described in section 904(d) of the Code in accordance with the proportions of the taxpayer's total foreign source federal taxable income (after reduction by the amount of foreign source portfolio dividends to which tax has been specifically allocated under Step One, above) in each grouping.
(iii) Effective dates. The rules of § 1.861-8(e)(6)(i) and the language preceding the examples in § 1.861-8(g) are effective for taxable years beginning after December 31, 1976. The rules of § 1.861-8(e)(6)(ii) (other than § 1.861-8(e)(6)(ii)(D)) and Examples 25 through 32 of § 1.861-8(g) are effective for taxable years beginning on or after January 1, 1988. The rules of § 1.861-8(e)(6)(ii)(D) and Example 33 of § 1.861-8(g) are effective for taxable years ending after March 12, 1991. At the option of the taxpayer, however, the rules of § 1.861-8(e)(6)(ii) (other than § 1.861-8(e)(6)(ii)(D)) and Examples 25 through 32 of § 1.861-8(g) may be applied with respect to deductions for state taxes incurred in taxable years beginning before January 1, 1988.
(7) Losses on the sale, exchange, or other disposition of property— (i) Allocation. The deduction allowed for loss recognized on the sale, exchange, or other disposition of a capital asset or property described in section 1231(b) shall be considered a deduction which is definitely related and allocable to the class of gross income to which such asset or property ordinarily gives rise in the hands of the taxpayer. Where the nature of gross income generated from the asset or property has varied significantly over several taxable years of the taxpayer, such class of gross income shall generally be determined by reference to gross income generated from the asset or property during the taxable year or years immediately preceding the sale, exchange, or other dispostion of such asset or property. Thus, for example, where an asset generates primarily sales income from domestic sources in the early years of its operation and then is leased by the taxpayer to a foreign subsidiary in later years, the class of gross income to which the asset gives rise will be considered to be the rental income derived from the lease and will not include sales income from domestic sources.
(ii) Apportionment of losses. Where in the unusual circumstances that an apportionment of a deduction for losses on the sale, exchange, or other disposition of a capital asset or property described in section 1231(b) is necessary, the amount of such deduction shall be apportioned between the statutory grouping (or among the statutory groupings) of gross income (within the class of gross income) and the residual grouping (within the class of gross income) in the same proportion that the amount of gross income within such statutory grouping (or statutory groupings) and such residual grouping bear, respectively, to the total amount of gross income within the class of gross income. Apportionment will be necessary where, for example, the class of gross income to which the deduction is allocated consists of gross income (such as royalties) attributable to an intangible asset used both within and without the United States, or gross income (such as from sales or services) attributable to a tangible asset used both within and without the United States.
(iii) Allocation of loss recognized in taxable years after 1986. See §§ 1.865-1 and 1.865-2 for rules regarding the allocation of certain loss recognized in taxable years beginning after December 31, 1986.
(8) Net operating loss deduction. A net operating loss deduction allowed under section 172 shall be allocated and apportioned in the same manner as the deductions giving rise to the net operating loss deduction.
(9) Deductions which are not definitely related. Deductions which shall generally be considered as not definitely related to any gross income, and therefore are ratably apportioned as provided in paragraph (c)(3) of this section, are—
(i) The deduction allowed by section 163 for interest described in subparagraph (2)(iii) of this paragraph (e);
(ii) The deduction allowed by section 164 for real estate taxes on a personal residence or for sales tax on the purchase of items for personal use;
(iii) The deduction for medical expenses allowed by section 213; and
(iv) The deduction for alimony payments allowed by section 215.
(10) Special deductions. The special deductions allowed in the case of a corporation by section 241 (relating to the deductions for partially tax exempt interest, dividends received, etc.), section 922 (relating to Western Hemisphere trade corporations), and section 941 (relating to China Trade Act corporations) shall be allocated and apportioned consistent with the principles of this section.
(11) Personal exemptions. The deductions for the personal exemptions allowed by section 151, 642(b), or 873(b)(3) shall not be taken into account for purpose of allocation and apportionment under this section.
(12) Deductions for certain charitable contributions— (i) In general. The deduction for charitable contributions that is allowed under sections 170, 873(b)(2), and 882(c)(1)(B) is definitely related and allocable to all of the taxpayer's gross income. The deduction allocated under this paragraph (e)(12)(i) shall be apportioned between the statutory grouping (or among the statutory groupings) of gross income and the residual grouping on the basis of the relative amounts of gross income from sources in the United States in each grouping.
(ii) Treaty provisions. If a deduction for charitable contributions not otherwise permitted by sections 170, 873(b)(2), and 882(c)(1)(B) is allowed under a U.S. income tax treaty, and such treaty limits the amount of the deduction based on a percentage of income arising from sources within the treaty partner, the deduction is definitely related and allocable to all of the taxpayer's gross income. The deduction allocated under this paragraph (e)(12)(ii) shall be apportioned between the statutory grouping (or among the statutory groupings) of gross income and the residual grouping on the basis of the relative amounts of gross income from sources within the treaty partner within each grouping.
(iii) Coordination with A deduction for a charitable contribution by a member of an affiliated group shall be allocated and apportioned under the rules of this section, § 1.861-14(e)(6), and § 1.861-14T(c)(1).
(iv) Effective date. (A) The rules of paragraphs (e)(12)(i) and (iii) of this section shall apply to charitable contributions made on or after July 28, 2004. Taxpayers may apply the provisions of paragraphs (e)(12)(i) and (iii) of this section to charitable contributions made before July 28, 2004, but during the taxable year ending on or after July 28, 2004.
(B) The rules of paragraphs (e)(12)(ii) of this section shall apply to charitable contributions made on or after July 14, 2005. Taxpayers may apply the provisions of paragraph (e)(12)(ii) of this section to charitable contributions made before July 14, 2005, but during the taxable year ending on or after July 14, 2005.
(f) Miscellaneous matters— (1) Operative sections. The operative sections of the Code which require the determination of taxable income of the taxpayer from specific sources or activities and which give rise to statutory groupings to which this section is applicable include the sections described below.
(i) Overall limitation to the foreign tax credit. Under the overall limitation to the foreign tax credit, as provided in section 904(a)(2) (as in effect before enactment of the Tax Reform Act of 1976, or section 904(a) after such enactment) the amount of the foreign tax credit may not exceed the tentative U.S. tax (i.e., the U.S. tax before application of the foreign tax credit) multiplied by a fraction, the numerator of which is the taxable income from sources without the United States and the denominator of which is the entire taxable income. Accordingly, in this case, the statutory grouping is foreign source income (including, for example, interest received from a domestic corporation which meets the tests of section 861(a)(1)(B), dividends received from a domestic corporation which has an election in effect under section 936, and other types of income specified in section 862 ). Pursuant to sections 862(b) and 863(a) and §§ 1.862-1 and 1.863-1, this section provides rules for identifying the deductions to be taken into account in determining taxable income from sources without the United States. See section 904(d) (as in effect after enactment of the Tax Reform Act of 1976) and the regulations thereunder which require separate treatment of certain types of income. See example 3 of paragraph (g) of this section for one example of the application of this section to the overall limitation.
(ii) [Reserved]
(iii) DISC and FSC taxable income. Sections 925 and 994 provide rules for determining the taxable income of a FSC and DISC, respectively, with respect to qualified sales and leases of export property and qualified services. The combined taxable income method available for determining a DISC's taxable income provides, without consideration of export promotion expenses, that the taxable income of the DISC shall be 50 percent of the combined taxable income of the DISC and the related supplier derived from sales and leases of export property and from services. In the FSC context, the taxable income of the FSC equals 23 percent of the combined taxable income of the FSC and the related supplier. Pursuant to regulations under section 925 and 994, this section provides rules for determining the deductions to be taken into account in determining combined taxable income, except to the extent modified by the marginal costing rules set forth in the regulations under sections 925(b)(2) and 994(b)(2) if used by the taxpayer. See Examples (22) and (23) of paragraph (g) of this section. In addition, the computation of combined taxable income is necessary to determine the applicability of the section 925(d) limitation and the “no loss” rules of the regulations under sections 925 and 994.
(iv) Effectively connected taxable income. Nonresident alien individuals and foreign corporations engaged in trade or business within the United States, under sections 871(b)(1) and 882(a)(1), on taxable income which is effectively connected with the conduct of a trade or business within the United States. Such taxable income is determined in most instances by initially determining, under section 864(c), the amount of gross income which is effectively connected with the conduct of a trade or business within the United States. Pursuant to sections 873 and 882(c), this section is applicable for purposes of determining the deductions from such gross income (other than the deduction for interest expense allowed to foreign corporations (see § 1.882-5 )) which are to be taken into account in determining taxable income. See example 21 of paragraph (g) of this section.
(v) Foreign base company income. Section 954 defines the term “foreign base company income” with respect to controlled foreign corporations. Section 954(b)(5) provides that in determining foreign base company income the gross income shall be reduced by the deductions of the controlled foreign corporation “properly allocable to such income”. This section provides rules for identifying which deductions are properly allocable to foreign base company
