Example.
On January 1, 1975, A, age 55, who is a calendar-year taxpayer, contributes $1,500 to an individual retirement account established for his benefit. For 1975, A is entitled to a deduction of $1,400 under section 219. For 1975, A does not claim as deductions any other items listed in section 62. A's gross income for 1975 is $9,334. On April 1, 1976, $107 is distributed to A from his individual retirement account. As of such date, the balance of the account is $1,498 [$1,605 − $107]. There were no other distributions from the account as of such date. The net amount of income earned by the account is $105 [$1,498 + $107 − (0 + $1,500)]. The net income attributable to the excess contribution is $7. [$105×($100/$1,500)]. A's adjusted gross income for 1975 is his gross income for 1975 ($9,334) reduced by the amount allowable to A as a deduction under section 219 ($1,400), or $7,934. A will include the $7 of the $107 distributed on April 1, 1976, in his gross income for 1976. Further, A will pay an additional income tax of $.70 for 1976 under section 408(f)(1).
