Sec. 1.861-9 Allocation and apportionment of interest expense and rules for asset-based apportionment.

(i) General rule. Any expense or loss (to the extent deductible) incurred in a transaction or series of integrated or related transactions in which the taxpayer secures the use of funds for a period of time is subject to allocation and apportionment under the rules of this section and §1.861-9T(b) if such expense or loss is substantially incurred in consideration of the time value of money. However, the allocation and apportionment of a loss under this paragraph (b) and §1.861-9T(b) does not affect the characterization of such loss as capital or ordinary for any purpose other than for purposes of the section 861 regulations (as defined in §1.861-8(a)(1)).

(ii) Examples. For further guidance, see §1.861-9T(b)(1)(ii).

(i) Partnership interest expense. A limited partner (whether individual or corporate), whose ownership, together with ownership by persons that bear a relationship to the partner described in section 267(b) or section 707, of the capital and profits interests of the partnership is less than 10 percent directly allocates its distributive share of partnership interest expense to its distributive share of partnership gross income. Under §1.904-4(n)(1)(ii), such a partner's distributive share of foreign source income of the partnership is treated as passive income (subject to the high-taxed income exception of section 904(d)(2)(B)(iii)(II)), except in the case of income from a partnership interest held in the ordinary course of the partner's active trade or business, as defined in §1.904-4(n)(1)(ii)(B). A partner's distributive share of partnership interest expense (other than partnership interest expense that is directly allocated to identified property under §1.861-10T) is apportioned in accordance with the partner's relative distributive share of gross foreign source income in each separate category and of gross domestic source income from the partnership. To the extent that partnership interest expense is directly allocated under §1.861-10T, a comparable portion of the income to which such interest expense is allocated is disregarded in determining the partner's relative distributive share of gross foreign source income in each separate category and domestic source income. The partner's distributive share of the interest expense of the partnership that is directly allocable under §1.861-10T is allocated according to the treatment, after application of §1.904-4(n)(1), of the partner's distributive share of the income to which the expense is allocated.

(ii) Other interest expense of the partner. For further guidance, see §1.861-9T(e)(4)(ii).

(i) In general. For purposes of apportioning interest expense that is not directly allocable under paragraph (e)(4) of this section or §1.861-10T, the disregarded portion of a downstream partnership loan is not considered an asset of a downstream partnership loan lender (DPL lender). The disregarded portion of a downstream partnership loan is the portion of the value of the loan (as determined under paragraph (h)(4)(i) of this section) that bears the same proportion to the total value of the loan as the matching income amount that is included by the DPL lender for a taxable year with respect to the loan bears to the total amount of downstream partnership loan interest income (DPL interest income) that is included directly or indirectly in gross income by the DPL lender with respect to the loan during that taxable year.

(ii) Treatment of interest expense and interest income attributable to a downstream partnership loan. If a DPL lender (or any other person in the same affiliated group as the DPL lender) takes into account a distributive share of downstream partnership loan interest expense (DPL interest expense), the DPL lender must assign an amount of DPL interest income corresponding to the matching income amount for the taxable year that is attributable to the same loan to the same statutory and residual groupings as the statutory and residual groupings of gross income from which the DPL interest expense is deducted (or would be deducted, without regard to any limitations on the deductibility of interest, such as section 163(j)) by the DPL lender (or any other person in the same affiliated group as the DPL lender).

(iii) Anti-avoidance rule for third party back-to-back loans. If, with a principal purpose of avoiding the rules in this paragraph (e)(8), a person makes a loan to a person that is not related (within the meaning of section 267(b) or 707) to the lender, the unrelated person makes a loan to a partnership, and the first loan would constitute a downstream partnership loan if made directly to the partnership, then the rules of this paragraph (e)(8) apply as if the first loan was made directly to the partnership and the interest expense paid by the partnership is treated as made with respect to the first loan. Such a series of loans will be subject to this recharacterization rule without regard to whether there was a principal purpose of avoiding the rules in this paragraph (e)(8) if the loan to the unrelated person would not have been made or maintained on substantially the same terms but for the loan of funds by the unrelated person to the partnership. The principles of this paragraph (e)(8)(iii) also apply to similar transactions that involve more than two loans and regardless of the order in which the loans are made.

(iv) Anti-avoidance rule for loans held by CFCs. A loan receivable held by a controlled foreign corporation with respect to a loan to a partnership in which a United States shareholder (as defined in §1.904-5(a)(4)(vi)) of the controlled foreign corporation owns an interest, directly or indirectly through one or more other partnerships or other pass-through entities (as defined in §1.904-5(a)(4)(iv)), is recharacterized as a loan receivable held directly by the United States shareholder with respect to the loan to such partnership for purposes of this paragraph (e)(8) if the loan was made or transferred with a principal purpose of avoiding the rules in this paragraph (e)(8). An appropriate amount of income derived by the United States shareholder (or any other person in the same affiliated group as the United States shareholder) from the controlled foreign corporation is treated as DPL interest income. Appropriate adjustments must be made to the value and characterization of the stock of the controlled foreign corporation under §§1.861-9 and 1.861-12 in order to reflect the portion of the downstream partnership loan held by the controlled foreign corporation that is disregarded under paragraph (e)(8)(i) of this section.

(v) Interest equivalents. The principles of this paragraph (e)(8) apply in the case of a partner, or any person in the same affiliated group as the partner, that takes into account a distributive share of an expense or loss (to the extent deductible) that is allocated and apportioned in the same manner as interest expense under §§1.861-9(b) and 1.861-9T(b) and has a matching income amount (treating such interest equivalent as interest income or expense for purposes of paragraph (e)(8)(vi)(B) of this section) with respect to the transaction that gives rise to that expense or loss.

(vi) Definitions. For purposes of this paragraph (e)(8), the following definitions apply.

(vii) Examples. The following examples illustrate the application of the rules in this paragraph (e)(8).

(i) In general. For purposes of apportioning interest expense that is not directly allocable under paragraph (e)(4) of this section or §1.861-10T, an upstream partnership loan debtor’s (UPL debtor) pro rata share of the value of the upstream partnership loan (as determined under paragraph (h)(4)(i) of this section) is not considered an asset of the UPL debtor taken into account as described in paragraphs (e)(2) and (3) of this section.

(ii) Treatment of interest expense and interest income attributable to an upstream partnership loan. If a UPL debtor (or any other person in the same affiliated group as the UPL debtor) takes into account a distributive share of upstream partnership loan interest income (UPL interest income), the UPL debtor (or any other person in the same affiliated group as the UPL debtor) assigns an amount of its distributive share of the UPL interest income equal to the matching expense amount for the taxable year that is attributable to the same loan to the same statutory and residual groupings using the same ratios as the statutory and residual groupings of gross income from which the upstream partnership loan interest expense (UPL interest expense) is deducted by the UPL debtor (or any other person in the same affiliated group as the UPL debtor). Therefore, the amount of the distributive share of UPL interest income that is assigned to each statutory and residual grouping is the amount that bears the same proportion to the matching expense amount as the UPL interest expense in that statutory or residual grouping bears to the total UPL interest expense of the UPL debtor (or any other person in the same affiliated group as the UPL debtor).

(iii) Anti-avoidance rule for third party back-to-back loans. If, with a principal purpose of avoiding the rules in this paragraph (e)(9), a partnership makes a loan to a person that is not related (within the meaning of section 267(b) or 707) to the lender, the unrelated person makes a loan to a direct or indirect partner in the partnership (or any person in the same affiliated group as a direct or indirect partner), and the first loan would constitute an upstream partnership loan if made directly to the direct or indirect partner (or person in the same affiliated group as a direct or indirect partner), then the rules of this paragraph (e)(9) apply as if the first loan was made directly by the partnership to the partner (or affiliate of the partner), and the interest expense paid by the partner is treated as made with respect to the first loan. Such a series of loans will be subject to the recharacterization rule in this paragraph (e)(9)(iii) without regard to whether there was a principal purpose of avoiding the rules in this paragraph (e)(9) if the loan to the unrelated person would not have been made or maintained on substantially the same terms but for the loan of funds by the unrelated person to the direct or indirect partner (or affiliate of the partner). The principles of this paragraph (e)(9)(iii) also apply to similar transactions that involve more than two loans and regardless of the order in which the loans are made.

(iv) Interest equivalents. The principles of this paragraph (e)(9) apply in the case of a partner, or any person in the same affiliated group as the partner, that takes into account a distributive share of income and has a matching expense amount (treating any interest equivalent described in paragraph (b) of this section and 1.861-9T(b) as interest income or expense for purposes of paragraph (e)(9)(v)(B) of this section) that is allocated and apportioned in the same manner as interest expense under paragraph (b) of this section and 1.861-9T(b).

(v) Definitions. For purposes of this paragraph (e)(9), the following definitions apply.

(vi) Examples. The following examples illustrate the application of this paragraph (e)(9).

(i) In general. In the application of the asset method described in paragraph (g) of this section, a domestic corporation —

(ii) Coordination with section 987(3). For purposes of computing foreign currency gain or loss under section 987(3) (including section 987 gain or loss recognized under §1.987-5), the rules of this paragraph (f)(2) do not apply. See §1.987-4.

(iii) Example. The following example illustrates the application of the rules in this paragraph (f)(2).

(i) In general. For purposes of computing subpart F income and tested income and computing earnings and profits for all Federal income tax purposes, the interest expense of a controlled foreign corporation may be apportioned using either the asset method described in paragraph (g) of this section or the modified gross income method described in paragraph (j) of this section, subject to the rules of paragraphs (f)(3)(ii) and (iii) of this section.

(ii) Manner of election. The election shall be made by filing the statement and providing the written notice described in § 1.964-1(c)(3)(ii) and (iii), respectively, at the time and in the manner described therein. For further guidance, see § 1.861-9T(f)(3)(ii).

(iii) and (iv) [Reserved]. For further guidance, see § 1.861-9T(f)(3)(iii) and (iv).

(i) In general. For purposes of computing earnings and profits of a noncontrolled 10-percent owned foreign corporation (as defined in section 904(d)(2)(E)) for federal tax purposes, the interest expense of a noncontrolled 10-percent owned foreign corporation may be apportioned using either the asset method described in § 1.861-9T(g) or the modified gross income method described in § 1.861-9T(j). A noncontrolled 10-percent owned foreign corporation that is not a controlled foreign corporation may elect to use a different method of apportionment than that elected by one or more of its shareholders. A noncontrolled 10-percent owned foreign corporation must use the same method of apportionment with respect to all its domestic corporate shareholders.

(ii) Manner of election. The election to use the asset method described in § 1.861-9T(g) or the modified gross income method described in § 1.861-9T(j) may be made either by the noncontrolled 10-percent owned foreign corporation or by the majority domestic corporate shareholders (as defined in § 1.964-1(c)(5)(ii)) on behalf of the noncontrolled 10-percent owned foreign corporation. The election shall be made by filing the statement and providing the written notice described in § 1.964-1(c)(3)(ii) and (iii), respectively, at the time and in the manner described therein.

(iii) Stock characterization. The stock of a noncontrolled 10-percent owned foreign corporation is characterized under the rules in §1.861-12(c)(4).

(i) For further guidance, see §1.861-9T(g)(1)(i).

(ii) A taxpayer may elect to determine the value of its assets on the basis of either the tax book value or the fair market value of its assets. However, for taxable years beginning after December 31, 2017, the fair market value method is not allowed with respect to allocations and apportionments of interest expense. See section 864(e)(2). For rules concerning the application of an alternative method of valuing assets for purposes of the tax book value method, see paragraph (i) of this section. For rules concerning the application of the fair market value method, see paragraph (h) of this section.

(iii) [Reserved].

(iv) For rules relating to earnings and profits adjustments by taxpayers using the tax book value method for the stock in certain 10 percent owned corporations, see §1.861-12(c)(2).

(v) [Reserved].

(i) General rule.

(ii) Special rule for qualified business units of domestic corporations with functional currency other than the U.S. dollar.

(iii) Adjustment for directly allocated interest. For further guidance, see §1.861-9T(g)(2)(iii).

(iv) Assets in intercompany transactions. For further guidance, see §1.861-9T(g)(2)(iv).

(i) Related party debt. For purposes of this section, the value of a debt obligation of a related person held by the taxpayer or another person related to the taxpayer equals the amount of the liability of the obligor related person.

(ii) Stock in related persons. The value of stock in a related person held by the taxpayer or by another person related to the taxpayer equals the sum of the following amounts reduced by the taxpayer's pro rata share of liabilities of such related person:

(iii) Example.

(i) The tax book value of section 168 property placed in service during or after the first taxable year to which the election to use the alternative tax book value method applies shall be determined as though such property were subject to the alternative depreciation system set forth in section 168(g) (or a successor provision) for the entire period that such property has been in service.

(ii) In the case of section 168 property placed in service prior to the first taxable year to which the election to use the alternative tax book value method applies, the tax book value of such property shall be determined under the depreciation method, convention, and recovery period provided for under section 168(g) for the first taxable year to which the election applies.

(iii) If a taxpayer revokes an election to use the alternative tax book value method (the prior election) and later makes another election to use the alternative tax book value method (the subsequent election) that is effective for a taxable year that begins within 3 years of the end of the last taxable year to which the prior election applied, the taxpayer shall determine the tax book value of its section 168 property as though the prior election has remained in effect.

(iv) The tax book value of section 168 property shall be determined without regard to the election to expense certain depreciable assets under section 179.

(v) Examples. The provisions of this paragraph (i)(1) are illustrated in the following examples:

Example 1. In 2000, a taxpayer purchases and places in service section 168 property used solely in the United States. In 2005, the taxpayer elects to use the alternative tax book value method, effective for the current taxable year. For purposes of determining the tax book value of its section 168 property, the taxpayer's depreciation deduction is determined by applying the method, convention, and recovery period rules of the alternative depreciation system under section 168(g)(2) as in effect in 2005 to the taxpayer's original cost basis in such property. In 2006, the taxpayer acquires and places in service in the United States new section 168 property. The tax book value of this section 168 property is determined under the rules of section 168(g)(2) applicable to property placed in service in 2006.

Example 2. Assume the same facts as in Example 1, except that the taxpayer revokes the alternative tax book value method election effective for taxable year 2010. Additionally, in 2011, the taxpayer acquires new section 168 property and places it in service in the United States. If the taxpayer elects to use the alternative tax book value method effective for taxable year 2012, the taxpayer must determine the tax book value of its section 168 property as though the prior election still applied. Thus, the tax book value of property placed in service prior to 2005 would be determined by applying the method, convention, and recovery period rules of the alternative depreciation system under section 168(g)(2) applicable to property placed in service in 2005. The tax book value of section 168 property placed in service during any taxable year after 2004 would be determined by applying the method, convention, and recovery period rules of the alternative depreciation system under section 168(g)(2) applicable to property placed in service in such taxable year.

(i) Except as provided in this paragraph (i)(2)(i), a taxpayer may elect to use the alternative tax book value method. For the taxpayer's first taxable year beginning after December 31, 2017, the Commissioner's approval is not required to switch from the fair market value method to the alternative tax book value method for purposes of apportioning interest expense. Any election made pursuant to this paragraph (i)(2)(i) shall apply to all members of an affiliated group of corporations as defined in §§ 1.861-11(d) and 1.861-11T(d). Any election made pursuant to this paragraph (i)(2)(i) shall apply to all subsequent taxable years of the taxpayer unless revoked by the taxpayer. Revocation of such an election, other than in conjunction with an election to use the fair market value method, for a taxable year prior to the sixth taxable year for which the election applies requires the consent of the Commissioner.

(ii) Example. The provisions of this paragraph (i)(2) are illustrated in the following example:

Example. Corporation X, a calendar year taxpayer, elects on its original, timely filed tax return for the taxable year ending December 31, 2007, to use the alternative tax book value method for its 2007 year. The alternative tax book value method applies to Corporation X's 2007 year and all subsequent taxable years. Corporation X may not, without the consent of the Commissioner, revoke its election and determine tax book value using a method other than the alternative tax book value method with respect to any taxable year beginning before January 1, 2012. However, Corporation X may automatically elect to change from the alternative tax book value method to the fair market value method for any open year.

(i) Step 1. For further guidance, see §1.861-9T(j)(2)(i).

(ii) Step 2. Moving to the next higher-tier controlled foreign corporation, combine the gross income of such corporation within each grouping with its pro rata share (as determined under principles similar to section 951(a)(2)) of the gross income net of interest expense of all lower-tier controlled foreign corporations held by such higher-tier corporation within the same grouping adjusted as follows:
