What the source establishes
- IRS Topic 410 explains that pension or annuity payments may be fully or partly taxable and points readers to separate rules for other retirement benefits.
- The topic distinguishes the return of after-tax basis from taxable amounts and discusses withholding and estimated-payment questions.
- The source does not cover Social Security taxation, so that issue must be checked separately rather than inferred from this page.
