Key Takeaways
- The taxable portion of a pension is taxed at ordinary rates, and the 2026 brackets run from 10% to 37% (IRS Rev. Proc. 2025-32).
- A pension funded entirely with pre-tax dollars is generally 100% taxable as ordinary income (IRS Topic No. 410).
- The Simplified Method divides after-tax cost by a fixed payment count; a single-life annuity starting at age 61 to 65 uses 260 anticipated payments (IRS Pub 575).
- Distributions before age 59.5 may add a 10% additional tax unless an exception applies (IRS Topic No. 558).
- An eligible rollover distribution paid to you carries mandatory 20% federal withholding, avoided only by a direct rollover (IRS, 2026).
- Required minimum distributions generally begin at age 73, rising to 75 for those born in 1960 or later, first due in 2035 (SECURE 2.0 Act of 2022).
- In 2026 the base Part B premium is $202.90, with IRMAA beginning above $109,000 single or $218,000 joint (Medicare, 2026).
Key 2026 Pension Tax Figures
Figures are for 2026; the age-75 RMD applies to those born in 1960 or later, first due in 2035.
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, known as your cost basis. If you never made after-tax contributions, the payments are generally fully taxable. For federal workers, see how the FERS pension and TSP work. Postal employees can review how the USPS pension works.
A pension funded with pre-tax dollars is taxed as ordinary income at your marginal federal rate, so each payment is generally fully taxable. A pension with after-tax contributions is only partly taxable, with the tax-free share figured under the IRS Simplified Method or General Rule. Distributions before age 59½ may add a 10% tax, and required minimum distributions generally start at age 73 (Source: IRS Topic No. 410, 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). A traditional defined-benefit pension is usually funded with pre-tax dollars, so each payment is fully taxable. If you paid after-tax amounts in, part of each check comes back tax-free.

The taxable portion is taxed at your ordinary marginal bracket, not at the lower long-term capital-gains rates. It stacks on top of wages, IRA withdrawals, and taxable Social Security, so a pension can push a retiree into a higher bracket. The 2026 brackets run from 10% to 37%, with the 22% bracket starting at $50,400 of taxable income for single filers and $100,800 for joint filers (Source: IRS Rev. Proc. 2025-32, 2026).
The 2026 standard deduction shelters a first layer of that income: $32,200 for married filing jointly and $16,100 for single, plus an added $2,050 (single) or $1,650 per spouse at age 65 or older (Source: IRS Rev. Proc. 2025-32, 2026). Under the One Big Beautiful Bill Act (P.L. 119-21), a separate $6,000 senior deduction per person age 65 or older applies for tax years 2025 through 2028.
Fully taxable vs. partially taxable: after-tax basis
A pension is 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. Only that basis returns to you free of tax; pre-tax contributions, employer contributions, and all investment growth are taxable when paid out. Not every retirement cash flow is treated as income, as explained in whether reverse mortgage income is taxable.
| Situation | How it is taxed |
|---|---|
| No after-tax contributions (typical defined-benefit pension) | Fully taxable as ordinary income |
| Some after-tax contributions (basis in contract) | Partially taxable; tax-free part 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 |
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. 411, 2026). Either way, the total amount you can exclude is capped at your total cost in the contract.
The Simplified Method divides your total cost by a fixed number of anticipated payments to set a flat tax-free amount per payment. For a single-life annuity, that count depends on your age at the annuity starting date, as set out below.
| Age at annuity starting date | Anticipated payments (single life) |
|---|---|
| 55 or under | 360 |
| 56 to 60 | 310 |
| 61 to 65 | 260 |
| 66 to 70 | 210 |
| 71 and older | 160 |
When more than one person will receive payments and the annuity starting date is after 1997, the count is based on the combined ages of the annuitants, spreading basis recovery across both lives (Source: IRS Publication 575, 2026).
| Combined ages at annuity starting date | 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: the tax-free vs. taxable split
This 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. 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: $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 100% taxable (Source: IRS Topic No. 410, 2026).
Because the exclusion is capped at total cost, the tax-free portion is temporary. Once basis is recovered, later payments become fully taxable. If a retiree dies before recovering the full cost, any unrecovered investment in the contract may be claimed as a deduction on the final income tax return (Source: IRS Publication 575, 2026).
Form 1099-R and where to report pension income
Your payer sends Form 1099-R each year showing what you received and how much is taxable. You report the gross amount on Form 1040 or 1040-SR line 5a and the taxable amount on line 5b (Source: IRS Instructions for Form 1040, 2026). When Box 2a is blank and Box 2b (taxable amount not determined) is checked, you figure the taxable share yourself, generally using the Simplified Method and the Box 9b cost figure.
| 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 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 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 |
Withholding, lump sum, and the mandatory 20%
Federal income tax is generally withheld from pension payments unless you elect otherwise, and the form depends on the payment type: periodic payments use Form W-4P, and nonperiodic or rollover distributions use Form W-4R (Source: IRS Pensions and Annuity Withholding, 2026). If you file no valid W-4P, a first periodic payment is withheld as if you were single with no adjustments.
| Form or situation | Withholding rule (2026) |
|---|---|
| W-4P, periodic pension or 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 |
Taking a pension as a lump sum instead of monthly payments changes the timing 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 over many years (Source: IRS Publication 575, 2026). A lump sum that is an eligible rollover distribution carries the mandatory 20% withholding; only a direct trustee-to-trustee rollover to an IRA or another plan avoids it and defers the tax.
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 (Source: IRS Publication 575, 2026; IRC section 402(e)(4)). Whether monthly income or a lump sum produces a lower lifetime tax bill depends on your facts, and some retirees model a partial Roth conversion to manage bracket timing.
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 additional tax equals 10% of the amount includible in gross income and is generally reported on Form 5329. The exceptions below can remove the 10% tax, though the underlying income usually remains taxable.
- Substantially equal periodic payments (SEPP) over your life expectancy
- Total and permanent disability
- Separation from service after reaching age 55
- Unreimbursed medical expenses exceeding 7.5% of adjusted gross income
- Qualified birth or adoption distributions up to $5,000 per child
- Distributions to victims of domestic abuse (after December 31, 2023)
RMDs, Social Security, and Medicare IRMAA
Required minimum distributions generally begin at age 73 for individuals who reach age 72 after December 31, 2022, and the amounts are taxed as ordinary income like the rest of a pension (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, so the earliest year an age-75 RMD is due is 2035.
See our guide to required minimum distributions in 2026 for the current divisor tables and deadlines.
Because pension income raises adjusted gross income, it can pull more of your Social Security into tax (up to 85% of benefits) and can lift your Medicare Part B premium through the income-related monthly adjustment amount (IRMAA). In 2026 the base Part B premium is $202.90, and IRMAA surcharges begin above $109,000 of modified adjusted gross income for single filers and $218,000 for joint filers, based on a two-year lookback (Source: Medicare, 2026).
Higher pension and RMD income can also expose investment income to the 3.8% net investment income tax once modified adjusted gross income passes $200,000 (single) or $250,000 (joint). This is why some retirees weigh how much to convert to Roth in lower-income years to reduce future taxable distributions.
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 pensions, some exempt part based on age or income, and several impose no broad personal income tax. States that generally do not tax private pension income include Illinois, Mississippi, and Pennsylvania, while others such as Alabama and Hawaii exempt defined-benefit pension payments. Pension timing also shapes federal planning, covered in Roth conversions before your pension starts. For how common pension income is, see what share of retirees have a pension.
Because state rules and thresholds shift year to year, many retirees confirm their own state against its department of revenue. For a current breakdown, see our companion guide to states that do not tax retirement income in 2026.

Frequently asked questions
How much of my pension income is taxable?
It depends on your after-tax basis. A pension funded entirely with pre-tax dollars is 100% taxable as ordinary income. If you made after-tax contributions, a fixed tax-free amount comes back with each payment under the Simplified Method until your basis is recovered, and the rest is taxable (Source: IRS Topic No. 410, 2026).
Do you pay federal taxes on pension income?
Yes, in most cases. The taxable portion of a pension is subject to federal income tax at your ordinary marginal rate and is reported on Form 1040 line 5b (Source: IRS Topic No. 410, 2026). The exceptions are the part of each payment that returns your after-tax cost basis and any qualified distribution from a designated Roth account, both of which are tax-free.
How can I avoid paying taxes on my pension?
You cannot avoid tax on the pre-tax portion of a pension, but you can manage the timing. Options many retirees weigh include recovering after-tax basis under the Simplified Method, using a direct rollover to defer tax on a lump sum, coordinating income to limit Social Security and IRMAA effects, and planning Roth conversions in lower-income years. Review these with a qualified professional.
At what age is pension income no longer taxed?
There is no age at which pension income becomes tax-free. The taxable portion is taxed as ordinary income regardless of age (Source: IRS Topic No. 410, 2026). Age affects other rules: the 10% additional tax on early distributions generally ends at age 59½, and required minimum distributions begin at age 73 (rising to 75 for those born in 1960 or later).
Is it better to take a pension as a lump sum or monthly payments?
Neither is better for everyone; the tax outcome depends on your facts. A lump sum is generally taxable in the year received and can land in a higher bracket, while monthly payments spread the taxable amount over many years (Source: IRS Publication 575, 2026). A direct rollover of a lump sum to an IRA defers the tax. Longevity, other income, and estate goals also factor in.
How much tax is withheld from a lump-sum pension payout?
An eligible rollover distribution paid directly to you carries mandatory 20% federal withholding, and that 20% is not optional (Source: IRS Pensions and Annuity Withholding, 2026). A direct trustee-to-trustee rollover to an IRA or another plan avoids the withholding entirely. A nonperiodic distribution that is not an eligible rollover distribution has a default 10% withholding rate you can adjust on Form W-4R.
What is the difference between the General Rule and the Simplified Method?
Both figure the tax-free share of a partly taxable pension, but they apply to different plans. The Simplified Method, used for most qualified employer plans with an annuity starting date after November 18, 1996, divides cost by a fixed anticipated-payments count. The General Rule uses IRS actuarial tables to build an exclusion ratio and applies to nonqualified and commercial annuities (Source: IRS Topic No. 411, 2026).
Where do I report pension income on my tax return?
Report the total distribution on Form 1040 or 1040-SR line 5a and the taxable portion on line 5b (Source: IRS Instructions for Form 1040, 2026). The figures come from 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, generally using the Simplified Method, before entering it on line 5b.
