(1) Group employees—(i) Number of employees. The number of group employees based in the relevant foreign country is at least 25 percent of the total number of group employees on the applicable date.

(3) Group income. The group income derived in the relevant foreign country is at least 25 percent of the total group income during the testing period.

(4) Tax residence of foreign acquiring corporation. The foreign acquiring corporation is a tax resident of the relevant foreign country. However, this paragraph (b)(4) does not apply if the relevant foreign country does not impose corporate income tax.

(c) Items not to be considered—(1) General rule. Except to the extent provided in paragraph (c)(2) of this section, the following items are not taken into account in the numerator, but are taken into account in the denominator, for each of the tests described in paragraphs (b)(1) through (3) of this section:

(i) Any group assets, group employees, or group income attributable to business activities that are associated with properties or liabilities the transfer of which is disregarded under section 7874(c)(4).

(ii) Any group assets or group employees located in, or group income derived in, the relevant foreign country as part of a plan with a principal purpose of avoiding the purposes of section 7874.

(iii) Any group assets or group employees located in, or group income derived in, the relevant foreign country if such group assets or group employees, or the business activities to which such group income is attributable, are subsequently transferred to another country in connection with a plan that existed at the time of the domestic entity acquisition .

Any group assets, group employees, or group income attributable to business activities that are associated with property that is transferred to the expanded affiliated group in a transfer that is disregarded under section 7874(c)(4) are not taken into account in the numerator or the denominator for each of the tests described in paragraphs (b)(1) through (3) of this section.

(d) Definitions and special rules. In addition to the definitions in § 1.7874-12, the following definitions and special rules apply for purposes of this section.

(1) The term applicable date means either of the following dates, applied consistently for all purposes of this section:

(i) The completion date; or

(ii) The last day of the month immediately preceding the month that includes the completion date.

(2) The term employee compensation means all amounts incurred by members of the expanded affiliated group that directly relate to services performed by group employees (including, for example, wages, salaries, deferred compensation, employee benefits, and employer payroll taxes). Employee compensation with respect to a particular group employee is treated as incurred when it would be deductible by the employer as compensation, and the amount of employee compensation equals the amount that would be deductible by the employer as compensation. Both the timing and the amount of the deduction for employee compensation must be determined for all group employees under U.S. federal income tax principles or for all group employees based on the relevant tax laws. Employee compensation is determined in U.S. dollars, translated, if necessary, using the weighted average exchange rate (as defined in § 1.989(b)-1) for the testing period.

(3) The term group assets means tangible personal property or real property used or held for use in the active conduct of a trade or business by members of the expanded affiliated group, provided such property is either owned or, in the circumstances described below, rented by members of the expanded affiliated group at the close of the completion date. A group asset is considered to be located in the relevant foreign country only if the asset was physically present in such country at the close of the completion date and the asset was physically present in such country for more time than in any other country during the testing period. Notwithstanding the foregoing, a group asset that is mobile in nature and is used in a transportation activity, such as a vessel, an aircraft, or a motor vehicle, is considered to be located in the relevant foreign country if the asset was physically present in such country for more time than in any other country during the testing period, regardless of whether the asset was physically present in such country at the close of the completion date. Group assets must be valued on a gross basis (that is, not reduced by liabilities) by consistently using for all group assets of the expanded affiliated group either the adjusted tax basis or fair market value determined in U.S. dollars, translated, if necessary, at the spot rate determined under the principles of § 1.988-1(d)(1), (2), and (4). Tangible personal property or real property that is rented by members of the expanded affiliated group from a person other than a member of the expanded affiliated group is also treated as a group asset, provided such property is used in the active conduct of a trade or business and is being rented by members of the expanded affiliated group at the close of the completion date. For purposes of this section, a group asset that is rented is valued at eight times the net annual rent paid or accrued with respect to the property by members of the expanded affiliated group.

(4) The term group employees means all individuals who are employees of members of the expanded affiliated group. Whether individuals are employees must be determined for all members of the expanded affiliated group under U.S. federal tax principles or for all members of the expanded affiliated group based on the relevant tax laws. A group employee is considered to be based in the relevant foreign country only if the employee spent more time providing services in such country than in any other single country during the testing period.

(5) The term group income means gross income of members of the expanded affiliated group from transactions occurring in the ordinary course of business with customers that are not related persons. Group income must be determined consistently for all members of the expanded affiliated group either under U.S. federal income tax principles or as reflected in the relevant financial statements. Group income is translated into U.S. dollars, if necessary, using the weighted average exchange rate (as defined in § 1.989(b)-1) for the testing period. Group income is considered derived in the relevant foreign country only if it is derived from a transaction with a customer located in such country.

(6) The term net annual rent means the annual rent paid or accrued with respect to property, less any payments received or accrued from subleasing such property (or other similar arrangement).

(7) The term related person has the meaning specified in section 954(d)(3), except that section 954(d)(3) is applied by substituting “one or more members of the expanded affiliated group” for “a controlled foreign corporation” and “the controlled foreign corporation” each place they appear.

(8) The term relevant financial statements means financial statements prepared consistently for all members of the expanded affiliated group in accordance with either U.S. Generally Accepted Accounting Principles (U.S. GAAP) or the International Financial Reporting Standards (IFRS) used for the expanded affiliated group's consolidated financial statements, but, if, after the domestic entity acquisition, financial statements will not be prepared consistently for all members of the expanded affiliated group in accordance with either U.S. GAAP or IFRS, then, for each member, financial statements prepared in accordance with either U.S. GAAP or IFRS. The relevant financial statements must take into account all items of income generated by all members of the expanded affiliated group for the entire testing period.

(9) The term relevant foreign country means the foreign country in which, or under the law of which, the foreign acquiring corporation was created or organized.

(10) The term relevant tax law means, for purposes of determining whether a particular individual who performs services for a member of the expanded affiliated group is an employee for purposes of paragraph (d)(6) of this section and the timing and amount of employee compensation for a particular employee of a member of the expanded affiliated group for purposes of paragraph (d)(3) of this section, the tax law to which the member is subject. Notwithstanding the foregoing, if the tax law to which a member is subject does not distinguish between whether an individual is an employee, or, for example, an independent contractor, then for this purpose the relevant tax law is considered to be U.S. federal tax law.

(11) The term tax resident means, with respect to a foreign country, a body corporate liable to tax under the laws of the country as a resident.

(12) The term testing period means the one-year period ending on the applicable date.

(e) Treatment of partnerships—(1) Stock held by a partnership. In determining the members of the expanded affiliated group for purposes of this section, each partner in a partnership, as determined without regard to the application of paragraph (e)(2) of this section, shall be treated as holding its proportionate share of the stock held by the partnership, as determined under the rules and principles of sections 701 through 777.

(2) Business activities of a partnership. For purposes of this section, if one or more members of the expanded affiliated group, as determined after the application of paragraph (e)(1) of this section, own, in the aggregate, more than 50 percent (by value) of the interests in a partnership, the partnership will be treated as a corporation that is a member of the expanded affiliated group. Thus, all items of such a partnership are taken into account for purposes of this section. No items of a partnership are taken into account for purposes of this section unless the partnership is treated as a member of the expanded affiliated group pursuant to this paragraph (e)(2).

(f) Applicability dates—(1) General rule. Except as otherwise provided in paragraph (f)(2) of this section, this section applies to domestic entity acquisitions that are completed on or after June 3, 2015. For acquisitions completed before June 3, 2015, see § 1.7874-3T as contained in 26 CFR part 1 revised as of April 1, 2016.

The first sentence of paragraph (b)(4) of this section applies to domestic entity acquisitions completed on or after November 19, 2015, and the second sentence applies to domestic entity acquisitions completed on or after July 12, 2018. Paragraph (d)(8) of this section applies to domestic entity acquisitions completed on or after April 4, 2016.
