Sec. 1.101-3 Interest payments.

(a) Applicability of section 101(c).

Section 101(c) provides that if any amount excluded from gross income by section 101(a) (relating to life insurance proceeds) or section 101(b) (relating to employees' death benefits) is held under an agreement to pay interest thereon, the interest payments shall be included in gross income. This provision applies to payments made (either by an insurer or by or on behalf of an employer) of interest earned on any amount so excluded from gross income which is held without substantial diminution of the principal amount during the period when such interest payments are being made or credited to the beneficiaries or estate of the insured or the employee. For example, if a monthly payment is $100, of which $99 represents interests and $1 represents diminution of the principal amount, the principal amount shall be considered held under an agreement to pay interest thereon and the interest payment shall be included in the gross income of the recipient. Section 101(c) applies whether the election to have an amount held under an agreement to pay interest thereon is made by the insured or employee or by his beneficiaries or estate, and whether or not an interest rate is explicitly stated in the agreement. Section 101(d), relating to the payment of life insurance proceeds at a date later than death, shall not apply to any amount to which section 101(c) applies. See section 101(d)(4). However, both section 101(c) and section 101(d) may apply to payments received under a single life insurance contract. For provisions relating to the application of this rule to payments received under a permanent life insurance policy with a family income rider attached, see paragraph (h) of section 1.101-4.

(b) Determination of "present value."

For the purpose of determining whether section 101(c) or section 101(d) applies, the present value (at the time of the insured's death) of any amount which is to be paid at a date later than death shall be determined by the use of the interest rate and mortality tables used by the insurer in determining the size of the payments to be made.
