(a) Method of accounting. (1) Section 818(a)(1) provides the general rule that all computations entering into the determination of taxes imposed by part I, subchapter L, chapter 1 of the Code, shall be made under an accrual method of accounting. Thus, the over-all method of accounting for life insurance companies shall be the accrual method. Except as otherwise provided in part I, the term “accrual method” shall have the same meaning and application in section 818 as it does under section 446 (relating to general rule for methods of accounting) and the regulations thereunder. For general rules relating to the taxable year for inclusion of income and deduction of expenses under an accrual method of accounting, see sections 451 and 461 and the regulations thereunder.

(2) Section 818(a)(2) provides that, to the extent permitted under this section, a life insurance company's method of accounting may be a combination of the accrual method with any other method of accounting permitted by chapter 1 of the Internal Revenue Code of 1954, other than the cash receipts and disbursements method. Thus, section 818(a)(2) specifically prohibits the use by a life insurance company of the cash receipts and disbursements method either separately or in combination with a permissible method of accounting. The term “method of accounting” includes not only the over-all method of accounting of the taxpayer but also the accounting treatment of any item. For purposes of section 818(a)(2), a life insurance company may elect to compute its taxable income under an over-all method of accounting consisting of the accrual method combined with the special methods of accounting for particular items of income and expense provided under other sections of chapter 1 of the Internal Revenue Code of 1954, other than the cash receipts and disbursements method. These methods of accounting for special items include the accounting treatment provided for depreciation (section 167), research and experimental expenditures (section 174), soil and water conservation expenditures (section 175), organizational expenditures (section 248), etc. In addition, a life insurance company may, where applicable, use the crop method of accounting (as provided in the regulations under sections 61 and 162), and the installment method of accounting for sales of realty and casual sales of personalty (as provided in section 453(b)). To the extent not inconsistent with the provisions of the Internal Revenue Code of 1954 or the regulations thereunder and the method of accounting adopted by the taxpayer pursuant to this section, all computations entering into the determination of taxes imposed by part I shall be made in a manner consistent with the manner required for purposes of the annual statement approved by the National Association of Insurance Commissioners.

(3)(i) An election to use any of the special methods of accounting referred to in subparagraph (2) of this paragraph which was made pursuant to any provisions of the Internal Revenue Code of 1954 or prior revenue laws for purposes of determining a company's tax liabilities for prior years, shall have the same force and effect in determining the items of gross investment income under section 804(b) and the items of deduction under section 804(c) of the Life Insurance Company Income Tax Act of 1959 (73 Stat. 112) as if such Act had not been enacted.

(ii) For purposes of determining gain or loss from operations under section 809(b), in computing the life insurance company's share of investment yield under section 809(b) (1)(A) and (2)(A), an election with respect to any of the special methods of accounting referred to in subparagraph (2) of this paragraph which was made pursuant to any provision of the Internal Revenue Code of 1954 or prior revenue laws, shall not be affected in any way by the enactment of the Life Insurance Company Income Tax Act of 1959 (73 Stat. 112).

(iii) For purposes of determining gain or loss from operations under section 809(b), in computing the items of gross amount under section 809(c) and the deduction items under section 809(d), an election to use any of the special methods of accounting referred to in subparagraph (2) of this paragraph must be made in accordance with the specific statutory provisions of the sections containing such elections and the regulations thereunder. However, where a particular election may be made only with the consent of the Commissioner (either because the time for making the election without the consent of the Commissioner has expired or because the particular section contained no provision for making an election without consent), and the time prescribed by the applicable regulations for submitting a request for permission to make such an election for the taxable year 1958 has expired, a life insurance company may make such an election for the year 1958 at the time of filing its return for that year (including extensions thereof). For example, a life insurance company may elect any of the methods of depreciation prescribed in section 167 (to the extent permitted under that section and the regulations thereunder) with respect to those assets, or any portion thereof, for which no depreciation was allowable under prior revenue laws, for example, furniture and fixtures used in the underwriting department. Similarly, a life insurance company shall be permitted to make an election under section 461(c) (relating to the accrual of real property taxes) with respect to real property for which no deduction was allowable under prior revenue laws. Any such election shall be made in the manner and form prescribed in the applicable regulations.

(iv) For purposes of subdivision (ii) of this subparagraph, the method used under section 1016(a)(3)(C) (relating to adjustments to basis) in determining the amount of exhaustion, wear and tear, obsolescence, and amortization actually sustained shall not preclude a taxpayer from electing any of the methods prescribed in section 167 in accordance with the provisions of that section and the regulations thereunder for determining the amount of such exhaustion, wear and tear, obsolescence, and amortization for the year 1958. For example, if the amount of depreciation actually sustained, under section 1016(a)(3)(C), on a life insurance company's home office building (other than that portion for which depreciation was allowable under prior revenue laws) is determined on the straight line method, the life insurance company may elect for the year 1958 to use any of the methods prescribed in section 167 for determining its depreciation allowance for 1958. However, such election shall be binding for 1958, and for all subsequent taxable years, unless consent to change such election, if required, is obtained from the Commissioner in accordance with the provisions of section 167 and the regulations thereunder.

(4)(i) For purposes of section 805(b)(3)(B)(i) (relating to the determination of the current earnings rate for any taxable year beginning before January 1, 1958), the determination for any year of the investment yield and the assets shall be made as though the taxpayer had been on the accrual method prescribed in subparagraph (1) of this paragraph for such year, or the accrual method in combination with the other methods of accounting prescribed in subparagraph (2) of this paragraph, if these other methods of accounting are used by the taxpayer in determining the investment yield and assets for the taxable year 1958. However, where the method used for determining the deduction under section 167 for the year 1958 differs from the method used in prior years, the amount of the deduction actually allowed or allowable for such prior years for purposes of section 1016(a)(2) (relating to adjustments to basis) shall be the amount to be taken into account in determining the current earnings rate under section 805(b)(3)(B)(i).

(ii) For purposes of section 812(b)(1)(C) (relating to operations loss carrybacks and carryovers for years prior to 1958), the determination for those years of the gain or loss from operations shall be made as though the taxpayer had been on the accrual method of accounting prescribed in subparagraph (1) of this paragraph for such year, or the accrual method in combination with the other methods of accounting prescribed in subparagraph (2) of this paragraph, if these other methods of accounting are used by the taxpayer in the determination of gain or loss from operations for the taxable year 1958. However, where any adjustment to basis is required under section 1016(a)(3)(C) on account of exhaustion, wear and tear, obsolescence, amortization, and depletion sustained, the amount actually sustained as determined under section 1016(a)(3)(C) for each of the years involved shall be the amount allowed in the determination of gain or loss from operations for purposes of section 812(b)(1)(C).

(b) Adjustments required if accrual method of accounting was not used in 1957. The items of gross amount taken into account under section 809(c) and the items of deductions allowed under section 809(d) for the taxable year 1958 shall be determined as though the taxpayer had been on the accrual method of accounting prescribed in paragraph (a) of this section for all prior years. Thus, life insurance companies not on the accrual method for the year 1957 shall accrue, as of December 31, 1957, those items of gross amount which would have been properly taken into account for the year 1957 if the company had been on the accrual method described in section 818(a). Likewise, life insurance companies not on the accrual method for the year 1957 shall accrue, as of December 31, 1957, those items of deductions which would have been properly allowed for the year 1957 if the company had been on the accrual method described in section 818(a). For example, if certain premium amounts were received during the year 1958 but such amounts would have been properly taken into account for the year 1957 if the taxpayer had been on the accrual method for the year 1957, then the taxpayer will not be required to take such premium amounts into account for the year 1958. If, for example, certain claims, benefits, and losses were paid during the year 1958 but such items would have been properly taken into account for the year 1957 if the taxpayer had been on the accrual method for the year 1957, then the taxpayer will not be permitted to deduct such expense items for the year 1958. For a special transitional rule applicable with respect to changes in method of accounting required by section 818(a) and paragraph (a) of this section, see section 818(e) and § 1.818-6.
