premiums earned on insurance contracts during the taxable year
(4) Premiums earned The term “premiums earned on insurance contracts during the taxable year” means an amount computed as follows: (A) From the amount of gross premiums written on insurance contracts during the taxable year, deduct return premiums and premiums paid for reinsurance. (B) To the result so obtained, add 80 percent of the unearned premiums on outstanding business at the end of the preceding taxable year and deduct 80 percent of the unearned premiums on outstanding business at the end of the taxable year. (C) To the result so obtained, in the case of a taxable year beginning after December 31, 1986 , and before January 1, 1993 , add an amount equal to 3⅓ percent of unearned premiums on outstanding business at the end of the most recent taxable year beginning before January 1, 1987 . For purposes of this subsection, unearned premiums shall include life insurance reserves, as defined in section 816(b) but determined as provided in section 807. For purposes of this subsection, unearned premiums of mutual fire or flood insurance companies described in paragraph (1)(D) means (with respect to the policies described in paragraph (1)(D)) the amount of unabsorbed premium deposits which the company would be obligated to return to its policyholders at the close of the taxable year if all of its policies were terminated at such time; and the determination of such amount shall be based on the schedule of unabsorbed premium deposit returns for each such company then in effect. Premiums paid by the subscriber of a mutual flood insurance company described in paragraph (1)(D) or issuing exclusively perpetual policies shall be treated, for purposes of computing the taxable income of such subscriber, in the same manner as premiums paid by a policyholder to a mutual fire insurance company described in subparagraph (C) or (D) of paragraph (1).
