How are pension payments taxed?
Pension payments are generally taxable as ordinary income for federal purposes. If you never made after-tax contributions to the plan, each payment is generally fully taxable; if you did, part of each payment is a tax-free return of that cost, figured under IRS rules.
Payments made at regular intervals for more than one year, such as lifetime pension payments, are periodic payments: the payer generally withholds federal tax like wages based on your Form W-4P, and you can usually adjust or decline withholding. Nonperiodic payments, such as a lump sum, use Form W-4R; if a lump sum is an eligible rollover distribution paid to you, the taxable portion is subject to mandatory withholding, which a direct rollover avoids. Withholding is a prepayment, not the final tax, so estimated payments may still be needed.
State income tax rules are separate and are not covered here.
