Example (5).
(i) D, a calendar year taxpayer, retired because of disability on June 30, 1965, receiving $100 per month under a plan which qualifies as a wage continuation plan for purposes of section 105(d) and § 1.105-4. Under the plan, the initial retirement age of D, whose birthday is January 1, is age 60 (January 1, 1967), and D's mandatory retirement age is age 70 (January 1, 1977). D had contributed $6,000 toward the cost of the annuity contract under such plan. For 1965 and 1966, D excluded under section 105(d) the entire amount received under the plan ($1600 and $1,200 respectively). For 1967 through 1973, D excluded $330 per year under section 72(b), or 27.5 percent of the $1,200 payment received under the plan per year.
(ii) In 1974, D realized that he will be entitled to use the exclusion provided in section 105(d) up until January 1, 1977, when he reaches his mandatory retirement age, and that he improperly applied section 72 to payments received in the years 1967 through 1973. In 1974, D filed a timely claim for refund with respect to the section 105(d) wage continuation benefits, for 1971, 1972 and 1973 (refunds for taxable year 1970 and prior years were barred by the statute of limitations), and continues to claim the section 105(d) exclusion for 1974, 1975 and 1976. D is entitled to an additional exclusion of $870 ($1,200−$330) for each of the years 1971, 1972 and 1973.
(iii) Upon reaching mandatory retirement age on January 1, 1977, D treats such date as the annuity starting date, and treats $6,000 as the investment in the contract. The investment in the contract is not reduced, because the amount excluded under section 72(b) for 1967 through 1970 ($330 per year) does not exceed the amount excludable under section 105(d) ($1,200 per year), and the $330 per year excluded for 1971, 1972, and 1973 were restored to the investment in the contract. Therefore, assuming that D would be entitled to exclude 41.3 percent of the payments under the plan if the annuity starting date is January 1, 1977, D would be entitled to exclude $495.60 (41.3 percent of $1,200) per annum.
