How is a pension taxed? In most cases a pension is taxed as ordinary income at your marginal federal rate, and the only part that escapes tax is the portion that returns your own after-tax contributions (your cost basis). If you never made after-tax contributions, the payments are generally fully taxable.
A pension paid from pre-tax dollars is generally taxable as ordinary income; a pension with after-tax contributions is partly taxable, with the tax-free part figured under the IRS Simplified Method or General Rule. Distributions before age 59½ may add a 10% tax, and required minimum distributions generally begin at age 73 (Source: IRS Topic No. 410, 2026; IRS RMD FAQs, 2026).
Is pension income taxable, and how much of it?
Pension income is generally taxable as ordinary income unless the payment is a qualified distribution from a designated Roth account, and how much is taxed turns on whether you contributed after-tax money to the plan (Source: IRS Topic No. 410, 2026). If you made no after-tax contributions, the full payment is generally taxable. If you did, part of each payment comes back tax-free.

A traditional defined-benefit pension is usually funded with pre-tax dollars, so each payment is generally fully taxable as ordinary income (Source: IRS Topic No. 410 / Publication 575, 2026). You had no tax on the money going in, so it is all taxed coming out.
If you paid after-tax amounts into the plan, you already paid tax on that money once. The IRS lets you recover that “investment in the contract” tax-free over time, so a slice of each payment is excluded and the rest is taxable (Source: IRS Topic No. 410, 2026).
Fully taxable vs. partially taxable: the role of cost basis
A pension is generally fully taxable if you made no after-tax contributions or have already recovered them, and partially taxable if you have unrecovered after-tax basis in the contract (Source: IRS Topic No. 410, 2026). “Cost basis,” also called your investment in the contract, is the total after-tax money you put in, and only that basis returns to you free of tax.
The distinction matters because only basis comes back tax-free. Pre-tax contributions, employer contributions, and investment growth are all taxable when paid out. After-tax employee contributions are the exception.
| Situation | How it is taxed |
|---|---|
| No after-tax contributions (typical DB pension) | Fully taxable as ordinary income |
| Some after-tax contributions (basis in contract) | Partially taxable; tax-free portion figured by Simplified Method or General Rule |
| Basis fully recovered | All later payments become fully taxable |
| Qualified distribution from designated Roth account | Entirely tax-free |
A qualified distribution from a designated Roth account inside a plan is entirely tax-free, because contributions were already taxed and qualified earnings are not taxed again (Source: IRS Topic No. 410, 2026).
The Simplified Method vs. the General Rule
Two methods figure the taxable share of a partly taxable pension, the Simplified Method and the General Rule. For a qualified employer plan with an annuity starting date after November 18, 1996, you generally must use the Simplified Method, while nonqualified and commercial annuities use the General Rule (Source: IRS Topic No. 410, 2026; IRS Topic No. 411, 2026). Either way, the amount excluded cannot exceed your total cost.
The Simplified Method applies to qualified employee plans, qualified employee annuities, and tax-sheltered 403(b) annuities (Source: IRS Topic No. 411, 2026). It divides your total cost by a fixed number of anticipated payments to set a flat tax-free amount per payment.
The General Rule (IRS Topic No. 411 and Publication 939) uses actuarial tables to build an exclusion ratio and applies to nonqualified plans and commercial annuities (Source: IRS Topic No. 411, 2026). Under either method, the total amount you can exclude is capped at your total cost in the contract (Source: IRS Topic No. 411, 2026).
Simplified Method: single-life anticipated payments
Under the Simplified Method for a single-life annuity, the number of anticipated payments depends on your age at the annuity starting date, and you divide your total cost by that number to find the tax-free amount in each monthly payment (Source: IRS Publication 575, 2026). The remainder of each payment is taxable as ordinary income, and the tax-free amounts continue until your basis is fully recovered.
| Age at annuity starting date | Number of anticipated payments (single life) |
|---|---|
| 55 or under | 360 |
| 56 to 60 | 310 |
| 61 to 65 | 260 |
| 66 to 70 | 210 |
| 71 and older | 160 |
Simplified Method: combined ages (more than one annuitant)
When more than one person will receive payments and the annuity starting date is after 1997, the anticipated-payments count under the Simplified Method is based on the combined ages of the annuitants (Source: IRS Publication 575, 2026). This applies to joint-and-survivor arrangements where a spouse or other beneficiary continues to receive payments after the first annuitant. The larger payment count spreads basis recovery across both lives.
| Combined ages at annuity starting date | Number of anticipated payments |
|---|---|
| 110 or under | 410 |
| 111 to 120 | 360 |
| 121 to 130 | 310 |
| 131 to 140 | 260 |
| 141 and over | 210 |
A worked example: figuring the tax-free vs. taxable split
This worked example shows the mechanics of a Simplified Method calculation using illustrative figures. Suppose a retiree begins a single-life pension at age 62 with $96,000 of after-tax cost basis and a $1,500 monthly payment. The steps below divide basis by anticipated payments to set the tax-free share of each check. It is educational only and is not a projection for any individual.
- Find the anticipated-payments number for age 62 (single life): 260 (Source: IRS Publication 575, 2026).
- Divide cost basis by anticipated payments: $96,000 ÷ 260 = $369.23 tax-free in each monthly payment.
- Subtract the tax-free part from the payment: $1,500 less $369.23 leaves $1,130.77 taxable each month.
- Annualize: about $4,431 tax-free and about $13,569 taxable per year, taxed at the retiree’s ordinary marginal rate.
- Continue until the tax-free amounts total $96,000. After that, every payment is fully taxable (Source: IRS Topic No. 410, 2026).
Because the exclusion is capped at total cost, the tax-free portion is temporary. Once basis is fully recovered, later payments are 100% taxable, which can raise a retiree’s taxable income in later years.
If a retiree dies before recovering the full cost, any unrecovered investment in the contract may be claimed as a miscellaneous itemized deduction on the final income tax return (Source: IRS Publication 575, 2026).
Pension income is taxed at your ordinary marginal rate
The taxable portion of a pension is generally taxed as ordinary income at your marginal federal bracket, not at the lower long-term capital-gains rates (Source: IRS Topic No. 410 / Publication 575, 2026). It stacks on top of other income such as wages, IRA withdrawals, and taxable Social Security, so pension income can move a retiree into a higher marginal bracket depending on total income.
Because pension income adds to adjusted gross income, it can also influence how much of your Social Security is taxed and which Medicare premium tier you land in. See the interaction between rising income and benefit taxation in our overview of the Social Security tax torpedo and the 2026 Medicare IRMAA brackets.
The 2026 standard deduction shelters a first layer of that income: $32,200 for married filing jointly, $16,100 for single or married filing separately, and $24,150 for head of household (Source: IRS Rev. Proc. 2025-32, 2026).
Form 1099-R and reporting on your return
Your payer sends Form 1099-R each year showing what you received and how much is taxable, and you report the gross amount and the taxable amount on your federal return (Source: IRS Topic No. 410, 2026). The taxable pension amount is reported on Form 1040 or 1040-SR, line 5b, with the gross distribution on line 5a (Source: IRS Instructions for Form 1040, 2026). The 1099-R boxes tell you most of what you need.
| 1099-R box | What it reports |
|---|---|
| Box 1, gross distribution | Total paid; flows to Form 1040 line 5a |
| Box 2a, taxable amount | Taxable portion; flows to Form 1040 line 5b (may be blank) |
| Box 2b, taxable amount not determined | Checked when the payer did not compute the taxable share |
| Box 5, employee contributions / after-tax recovered | After-tax amount recovered tax-free this year |
| Box 7, distribution code | Type of distribution (for example, early or normal) |
| Box 9b, total employee contributions | Your cost basis in the contract |
When Box 2a is blank and Box 2b is checked, the payer has left it to you to figure the taxable amount, generally using the Simplified Method and the Box 9b cost figure. Report the full distribution on line 5a and the taxable part on line 5b (Source: IRS Topic No. 410, 2026; IRS Instructions for Forms 1099-R and 5498, 2026).
Federal withholding: Form W-4P and Form W-4R
Federal income tax is generally withheld from pension payments unless you elect otherwise, and the form you use depends on the payment type (Source: IRS Topic No. 410, 2026; IRS Pensions and Annuity Withholding, 2026). Periodic payments use Form W-4P, and nonperiodic or rollover distributions use Form W-4R. You can elect out of withholding on periodic payments, but you may then owe estimated tax during the year.
If you file no valid W-4P, the default for a first periodic payment after 2021 treats you as “Single” with no adjustments in Steps 2 through 4 of the current Form W-4P (Source: IRS About Form W-4P, 2026). That default can under-withhold or over-withhold, so many retirees file the form to adjust it.
| Form / situation | Withholding rule (2026) |
|---|---|
| W-4P, periodic pension/annuity payments | Withheld per your elections; you may elect zero and pay estimated tax instead |
| W-4R, nonperiodic distribution (not eligible rollover) | Default withholding rate is 10% |
| Eligible rollover distribution paid to you | Mandatory 20% withholding unless done as a direct rollover |
The 20% is not optional on an eligible rollover distribution paid to you; only a direct trustee-to-trustee rollover avoids it (Source: IRS Pensions and Annuity Withholding, 2026). Nonresident aliens are generally subject to separate withholding under IRC section 1441, and payers should not rely on Form W-4P or W-4R from them (Source: same, 2026).
Lump sum vs. monthly annuity: different tax consequences
Taking a pension as a lump sum instead of monthly payments changes both the timing and character of the tax. A lump sum paid to you is generally includible in income in the year received, while monthly payments spread the taxable amount across many years (Source: IRS Publication 575, 2026). Because the taxable portion stacks on other income, a large single-year distribution may fall in a higher marginal bracket than income spread over time.
A lump sum that is an eligible rollover distribution carries mandatory 20% withholding unless moved by direct rollover to an IRA or another plan (Source: IRS Pensions and Annuity Withholding, 2026). Rolling it over defers tax until you later withdraw from the receiving account.
If a lump-sum distribution includes employer securities, net unrealized appreciation (NUA) rules may allow the appreciation to be taxed later at long-term capital-gains rates rather than as ordinary income; the rules are technical and fact-specific (Source: IRS Publication 575, 2026; IRC section 402(e)(4)). See our explainer on net unrealized appreciation. A 10-year tax option (forward averaging) remains available only for a qualified lump-sum distribution to a plan participant born before January 2, 1936 (Source: IRS Publication 575, 2026; IRS Form 4972, 2026).
Whether monthly income or a lump sum produces a lower lifetime tax bill depends on individual facts, and some retirees model a partial Roth conversion alongside the decision to manage bracket timing. These are factors to weigh with a qualified professional, not a recommendation.
Early distributions and the 10% additional tax
A distribution taken before age 59½ may trigger a 10% additional tax on the taxable portion, on top of ordinary income tax, unless an exception applies (Source: IRS Topic No. 558, 2026). The extra tax equals 10% of the amount includible in gross income. The exceptions below can remove the 10% additional tax, though the underlying income generally remains taxable.
- Substantially equal periodic payments (SEPP) over your life expectancy (Source: IRS Topic No. 558, 2026)
- Total and permanent disability
- Separation from service after reaching age 55
- Deductible medical expenses exceeding 7.5% of AGI
- ESOP dividends
- Qualified birth or adoption distributions up to $5,000 per child from a defined contribution plan
- Distributions to victims of domestic abuse (after December 31, 2023)
The additional tax is generally reported on Form 5329 (Source: IRS Topic No. 558, 2026; IRS Instructions for Form 5329, 2026). The exception list above is not exhaustive, and each exception has its own conditions.
Required minimum distributions (RMDs) and pensions
Required minimum distributions generally begin at age 73 for individuals who reach age 72 after December 31, 2022, with the required beginning date being April 1 of the year after you turn 73 (Source: IRS RMD FAQs, 2026). Under the SECURE 2.0 Act of 2022, the applicable RMD age rises to 75 for individuals born in 1960 or later, effective in 2033 (Source: SECURE 2.0 Act of 2022, section 107; IRS RMD FAQs, 2026).
RMD amounts are taxed as ordinary income like the rest of the pension. Workplace-plan participants who are not 5% owners may generally defer RMDs until the year they actually retire (Source: IRS RMD FAQs, 2026). For a fuller treatment, see our guide to required minimum distributions in 2026.
Missing an RMD carries a 25% excise tax on the shortfall, reduced to 10% if the miss is corrected within the correction window, generally two years (Source: SECURE 2.0 Act of 2022, section 302; IRS RMD FAQs, 2026). Traditional defined-benefit pensions paid as a lifetime annuity generally satisfy the RMD rules through the annuity payments themselves.
Survivor and beneficiary annuities
A survivor or beneficiary who continues to receive pension payments is generally taxed under the same rules that applied to the original annuitant, as set out in IRS Publication 575 (Source: IRS Publication 575, 2026). The survivor keeps recovering any remaining cost basis tax-free until it is used up, so part of each continuing payment may remain excluded from income.
For a joint-and-survivor annuity, the Simplified Method uses the combined-ages table to set the anticipated-payments count, spreading the tax-free recovery across both lifetimes (Source: IRS Publication 575, 2026). If cost basis remains unrecovered when payments end, a miscellaneous itemized deduction for the balance may be available on the final return (Source: IRS Publication 575, 2026).
State income tax on pensions
State treatment of pension income varies widely and is separate from federal rules, so it must be verified state by state (Source: IRS Topic No. 410, 2026). Some states fully tax pension income, some exempt part of it based on age or income thresholds, and others do not impose a broad personal income tax. Rules and dollar thresholds change over time, so a current-year check is warranted.
Because published state counts and rules shift year to year, confirm your own state against its department of revenue. For a current, state-by-state breakdown, see our companion guide to states that do not tax retirement income in 2026. This federal guide does not attempt a full state-by-state ranking.

Frequently asked questions
Is all pension income taxable?
Not always all of it. Pension income is generally fully taxable if you made no after-tax contributions or have already recovered them, and partially taxable if you have unrecovered after-tax basis in the contract. A qualified distribution from a designated Roth account is entirely tax-free (Source: IRS Topic No. 410, 2026). Most traditional defined-benefit pensions are fully taxable as ordinary income.
How do I know how much of my pension is taxable?
Check Form 1099-R. If Box 2a shows a taxable amount, that is generally your taxable portion. If Box 2a is blank and Box 2b is checked, you figure it yourself, generally using the Simplified Method: divide your cost basis (Box 9b) by the anticipated-payments number for your age to get the tax-free part of each payment (Source: IRS Topic No. 410, 2026; Publication 575, 2026). The remainder is taxable.
Where do I report pension or annuity income on my return?
Report the total distribution on Form 1040 or 1040-SR line 5a and the taxable portion on line 5b (Source: IRS Topic No. 410, 2026; IRS Instructions for Form 1040, 2026). The figures come from your Form 1099-R, where Box 1 is the gross amount and Box 2a is the taxable amount. If Box 2a is blank, you calculate the taxable share before entering it on line 5b, generally using the Simplified Method.
What is the difference between Form W-4P and Form W-4R?
Form W-4P sets withholding on periodic pension and annuity payments, such as monthly checks, and you may elect out of withholding on it (Source: IRS Topic No. 410, 2026). Form W-4R sets withholding on nonperiodic payments and rollovers; the default rate on a nonperiodic distribution that is not an eligible rollover distribution is 10% (Source: IRS Pensions and Annuity Withholding, 2026). Eligible rollover distributions paid to you carry mandatory 20% withholding.
Do I pay the 10% early withdrawal penalty on my pension?
A distribution before age 59½ may add a 10% tax on the taxable portion, on top of ordinary income tax (Source: IRS Topic No. 558, 2026). Exceptions include substantially equal periodic payments, total and permanent disability, separation from service after age 55, and certain birth, adoption, medical, or domestic-abuse situations. The income generally remains taxable even when the additional tax is waived.
At what age do RMDs start, and are they taxed?
Required minimum distributions generally begin at age 73 for those who reach age 72 after December 31, 2022, with the required beginning date on April 1 of the following year. Under the SECURE 2.0 Act, the applicable age rises to 75 for those born in 1960 or later, effective 2033. RMDs are taxed as ordinary income (Source: SECURE 2.0 Act of 2022, section 107; IRS RMD FAQs, 2026).
Is a lump-sum pension taxed differently than monthly payments?
The timing differs. A lump sum paid to you is generally includible in income in the year received, while monthly payments spread the taxable amount over many years (Source: IRS Publication 575, 2026). An eligible rollover distribution paid to you carries mandatory 20% withholding unless moved by direct rollover. If the lump sum includes employer securities, net unrealized appreciation rules may apply (Source: IRS Publication 575, 2026; IRC section 402(e)(4)).
