Example: D, a partner in the DEF partnership, retired from the partnership as of December 31, 1976. The taxable year of both D and the partnership is the calendar year. During the partnership's taxable year ending December 31, 1977, D rendered no service to any trade or business carried on by the partnership. On or before December 31, 1977, all obligations (other than retirement payments under the plan) from the other partners to D were liquidated, and D's share of the capital of the partnership was paid to him. Retirement payments received by D under the partnership's plan in his taxable year ending December 31, 1977, are excluded in determining net earnings from self-employment (if any) for that taxable year.
