(3) Other definitions and special rules For purposes of this subsection— (A) Flexible premium life insurance contract The terms “flexible premium life insurance contract” and “contract” mean a life insurance contract (including any qualified additional benefits) which provides for the payment of one or more premiums which are not fixed by the insurer as to both timing and amount. Such terms do not include that portion of any contract which is treated under State law as providing any annuity benefits other than as a settlement option. (B) Premiums paid The term “premiums paid” means the premiums paid under the contract less any amounts (other than amounts includible in gross income) to which section 72(e) applies. If, in order to comply with the requirements of paragraph (1)(A), any portion of any premium paid during any contract year is returned by the insurance company (with interest) within 60 days after the end of a contract year— (i) the amount so returned (excluding interest) shall be deemed to reduce the sum of the premiums paid under the contract during such year, and (ii) notwithstanding the provisions of section 72(e), the amount of any interest so returned shall be includible in the gross income of the recipient. (C) Applicable percentage The term “applicable percentage” means— (i) 140 percent in the case of an insured with an attained age at the beginning of the contract year of 40 or less, and (ii) in the case of an insured with an attained age of more than 40 as of the beginning of the contract year, 140 percent reduced (but not below 105 percent) by one percent for each year in excess of 40. (D) Cash value The cash value of any contract shall be determined without regard to any deduction for any surrender charge or policy loan. (E) Qualified additional benefits The term “qualified additional benefits” means any— (i) guaranteed insurability, (ii) accidental death benefit, (iii) family term coverage, or (iv) waiver of premium. (F) Premium payments not disqualifying contract The payment of a premium which would result in the sum of the premiums paid exceeding the guideline premium limitation shall be disregarded for purposes of paragraph (1)(A)(i) if the amount of such premium does not exceed the amount necessary to prevent the termination of the contract without cash value on or before the end of the contract year. (G) Net single premium In computing the net single premium under paragraph (1)(B)— (i) the mortality basis shall be that guaranteed under the contract (determined by reference to the most recent mortality table allowed under all State laws on the date of issuance), (ii) interest shall be based on the greater of— (I) an annual effective rate of 4 percent (3 percent for contracts issued before July 1, 1983 ), or (II) the minimum rate or rates guaranteed upon issue of the contract, and (iii) the computational rules of paragraph (2)(D) shall apply, except that the maturity date referred to in clause (ii) thereof shall not be earlier than age 95. (H) Correction of errors If the taxpayer establishes to the satisfaction of the Secretary that— (i) the requirements described in paragraph (1) for any contract year was not satisfied due to reasonable error, and (ii) reasonable steps are being taken to remedy the error, the Secretary may waive the failure to satisfy such requirements.
