26 CFR § 1.404(a)-10 - Profit-sharing plan of an affiliated group; application of section 404(a)(3)(B).
(a) Section 404(a)(3)(B) allows a corporation a deduction to the extent provided in paragraphs (b) and (c) of this section for a contribution which it makes for another corporation to a profit-sharing plan or a stock bonus plan under which contributions are determined by reference to profits, provided the following tests are met:
(1) The corporation for which the contribution is made and the contributing corporation are members of an affiliated group of corporations as defined in section 1504, relating to the filing of consolidated returns, and both such corporations participate in the plan. However, it is immaterial whether all the members of such group participate in the plan.
(2) The corporation for which the contribution is made is required under the plan to make the contribution, but such corporation is prevented from making such contribution because it has neither current nor accumulated earnings or profits, or because its current and accumulated earnings or profits are insufficient to make the required contribution. To the extent that such a corporation has any current or accumulated earnings or profits, it is not considered to be prevented from making its required contribution to the plan.
(b) The amount that is deductible under section 404(a)(3)(B) is determined by applying the rules of section 404(a)(3)(A) and as if the contribution were made by the corporation for which it is made. The contributing corporation may deduct the amount so determined subject to the limitations contained in paragraph (c) of this section. The contributing corporation shall not treat such amount as a contribution made by it in applying the rules of section 404(a)(3)(A) and either for the taxable year for which the contribution is made or for succeeding taxable years. The corporation for which the contribution is made shall treat the contribution as having been made by it in applying the rules of section 404(a)(3)(A) for succeeding taxable years.
(c) The allowance of the deduction under section 404(a)(3)(B) does not depend upon whether the affiliated group does or does not file a consolidated return. If a consolidated return is filed, it is immaterial which of the participating corporations makes the contribution and takes the deduction or how the contribution or the deduction is allocated among them. However, if a consolidated return is not filed, the contribution which is deductible under section 404(a)(3)(B) by each contributing corporation shall be limited to that portion of its total current and accumulated earnings or profits (adjusted for its contribution deductible without regard to section 404(a)(3)(B)) which the prevented contribution bears to the total current and accumulated earnings or profits of all the participating members of the group having such earnings or profits (adjusted for all contributions deductible without regard to section 404(a)(3)(B)). For the purpose of this section, current earnings or profits shall be computed as of the close of the taxable year without diminution by reason of any dividends during the taxable year, and accumulated earnings or profits shall be computed as of the beginning of the taxable year.
(2) Earnings and profits of the taxable year.
(3) Accumulated earnings and profits at beginning of taxable year.
(4) Total current and accumulated earnings and profits (column 2 plus column 3).
(5) Compensation of participating employees.
(6) Contribution formula: 50 percent of consolidated earnings and profits, allocated among participating member in proportion of covered payroll of each to covered payroll of consolidated group.
(7) Individual contribution had it not been prevented.
(8) Individual contribution made by each employer for its own employees.
(9) Balance of accumulated earnings and profits (column 4 minus column 8).
(10) Proportion of make-up contribution.
(11) Make-up contribution.
