How are annuity distributions taxed
Publication 575 - Main Content
Disability pensions. You receive disability payments because you retired on disability and have not reached minimum retirement age.
More than one program. You may receive employee plan benefits from more than one program under a single trust or plan of your employer. If you participate in more than one program, you may have to treat each as a separate pension or annuity contract, depending upon the facts in each case. Also, you may be considered to have received more than one pension or annuity. Your former employer or the plan administrator should be able to tell you if you have more than one contract.
Your employer set up a noncontributory profit-sharing plan for its employees. The plan provides that the amount held in the account of each participant will be
paid when that participant retires. Your employer also set up a contributory defined benefit pension plan for its employees providing for the payment of a lifetime pension to each participant after retirement.
The amount of any distribution from the profit-sharing plan depends on the contributions (including allocated forfeitures) made for the participant and the earnings from those contributions. Under the pension plan, however, a formula determines the amount of the pension benefits. The amount of contributions is the amount necessary to provide that pension.
Each plan is a separate program and a separate contract. If you get benefits from these plans, you must account for each separately, even though the benefits from both may be included in the same check.
Distributions from a designated Roth account are treated separately from other distributions from the plan.Source: www.irs.gov
