Example.
A is an employee of X Organization (an employer described in section 501(c)(3) and exempt from tax under section 501(a) ) for the entire calendar year 1964. A uses the calendar year as a taxable year. A's annual salary as of January 1, 1964, is $12,000. On February 1, 1964, A and his employer enter a binding and irrevocable agreement whereby A is to take a 10-percent reduction in salary (from $1,000 per month to $900 per month) and X Organization is to contribute $100 per month for an annuity contract described in section 403(b). The agreement also provides that A may terminate the entire agreement with respect to amounts not yet earned. Since the agreement to reduce A's salary and invest the amount of such reduction in an annuity contract was made after A earned his salary for January, A's current compensation for January is $1,000 even though the agreement may provide that X Organization shall contribute $100 with respect to January for the benefit of A for an annuity contract described in section 403(b). For February and subsequent months ending before July 1, 1964, X Organization contributes $100 per month for A's annuity. Thus, A's current compensation for each of these months is $900, and the $100 which is contributed during such months by X Organization for an annuity contract for A is an employer contribution to which the exclusion provided in this paragraph applies. On July 1, 1964, A becomes entitled to a salary increase of $200 per month and, pursuant to the agreement of February 1, 1964, X Organization contributes 10 percent of such increase or an additional $20 per month for a section 403(b) annuity. For July and subsequent months ending before October 1, 1964, X Organization contributes $120 per month for A's annuity. Thus, A's current compensation for each of these months is $1,080, and the $120 which is contributed during such months by X Organization for an annuity contract for A is an employer contribution to which the exclusion provided in this paragraph applies. On November 1, 1964, A terminates the entire agreement with respect to amounts not yet earned. Since the termination occurred after A earned his salary for the month of October, the contribution for October is an employer contribution to which the exclusion provided in this paragraph applies. For the months November and December, A's full salary of $1,200 per month is includible in his gross income whether or not his employer makes contributions for a section 403(b) annuity.
