Treas. Reg. § 1.404(a)-8 — Contributions of an employer under an employees' annuity plan which meets the requirements of section 401(a); application of section 404(a)(2).

(a) If contributions are paid by an employer under an annuity plan for employees and the general conditions and limitations applicable to deductions for such contributions are satisfied (see § 1.404(a)-1), the contributions are deductible under section 404(a)(2) if the further conditions provided therein are satisfied. For the meaning of “annuity plan” as used here, see § 1.404(a)-3. In order that contributions by the employer may be deducted under section 404(a)(2), all of the following conditions must be satisfied:

(1) The contributions must be paid toward the purchase of retirement annuities (or for disability, severance, insurance, survivorship benefits incidental and directly related to such annuities, or medical benefits described in section 401(h) as defined in paragraph (a) of § 1.404(h)-1) under an annuity plan for the exclusive benefit of the employer's employees or their beneficiaries.

(2) The contributions must be paid in a taxable year of the employer which ends with or within a year of the plan for which it meets the applicable requirements set forth in section 401(a) (3), (4), (5), (6), (7), (8), (11), (12), (13), (14), (15), (16), and (19). In the case of a plan which covers a self-employed individual, the contributions must be paid in a taxable year of the employer which ends with or within a year of the plan for which it also meets the requrements of section 401(a), (9), (10), (17), and (18) and of section 401(d) (other than paragraph (1)). In the case of a plan which covers a shareholder-employee within the meaning of section 1379(d), the contributions must be paid in a taxable year of the employer which ends with or within a year of the plan for which it also meets the requirements of section 401(a) (17) and (18). See section 401(a) and the regulations thereunder for the requirements and the applicable effective dates of the respective paragraphs set forth in section 401(a). Any contributions of an employer which are paid in a taxable year of the employer ending with or within a year of the plan for which it meets the applicable requirements of section 401 may be carried over and deducted in a succeeding taxable year of the employer in accordance with section 404(a)(1)(D), whether or not such succeeding taxable year ends with or within a taxable year of the plan for which it meets the requirements set out in section 401 (a) and (d). See section 401(b) and the regulations thereunder for special rules allowing certain plan amendments to be given retroactive effect. See section 404(a)(6) for a special rule for determining the time when a contribution is deemed to have been made.

(3) There must be a definite written arrangement between the employer and the insurer that refunds of premiums, if any, shall be applied within the taxable year of the employer in which received or within the next succeeding taxable year toward the purchase of retirement annuities (or for disability, severance, insurance, survivorship benefits incidental and directly related to such annuities, or medical benefits described in section 401(h) as defined in paragraph (a) of § 1.401(h)-1 under the plan. For the purpose of this condition, “refunds of premiums” means payments by the insurer on account of credits such as dividends, experience rating credits, or surrender or cancellation credits. The arrangement may be in the form of contract provisions or written directions of the employer or partly in one form and partly in another. This condition will be considered satisfied where -

(i) All credits are applied regularly, as they are determined, toward the premiums next due under the contracts before any further employer contributions are so applied, and

(ii) Under the arrangement,

(A) No refund of premiums may be made during continuance of the plan unless applied as aforesaid, and

(B) If refunds of premiums may be made after discontinuance or termination, whichever is applicable, of the plan on account of surrenders or cancellations before all retirement annuities provided under the plan with respect to service before its discontinuance or termination have been purchased, such refunds will be applied in the taxable year of the employer in which received, or in the next succeeding taxable year, to purchase retirement annuities for employees by a procedure which does not contravene the conditions of section 401(a)(4). If the plan also includes medical benefits described in section 401(h) as defined in paragraph (a) of § 1.401(h)-1, any refund of premiums attributable to such benefits must, in accordance with these rules, be applied toward the purchase of medical benefits described in section 401(h).

(4) Any amounts described in subparagraph (3) of this paragraph which are attributable to contributions on behalf of a self-employed individual must be applied toward the purchase of retirement benefits. Amounts which are so applied are not contributions and thus are not taken into consideration in determining -

(i) The amount deductible with respect to contributions on his behalf, nor

(ii) In the case of an owner-employee, the maximum amount of contributions that may be made on his behalf.
