How Much Tax Will I Pay on My Pension Income?

Pension income is taxed as ordinary income at your regular federal rate, which in 2026 runs from 10% to 37% depending on your total taxable income.¹ How much tax you will actually pay on your pension income depends on three things: which bracket your total income lands in, whether any part of the payment represents after-tax money you already paid tax on, and what other retirement income you receive alongside it. If your employer funded the whole plan or your contributions came out pre-tax, every dollar is taxable. If you put in after-tax money, a slice of each check comes back to you tax-free.

Your Federal Bracket Sets the Rate

Pension payments do not get a preferential rate. They stack on top of your other income (Social Security, IRA withdrawals, part-time wages, interest) and the combined total decides your bracket. There is no capital-gains-style discount for pension money.

For 2026, the federal brackets for single filers are:¹

10% up to $12,400
12% from $12,401 to $50,400
22% from $50,401 to $105,700
24% from $105,701 to $201,775
32% from $201,776 to $256,225
35% from $256,226 to $640,600
37% over $640,600

Married couples filing jointly get wider brackets. The 12% bracket extends to $100,800, and the 37% rate does not kick in until income exceeds $768,700.¹

The 2026 standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, with an additional amount for filers age 65 and older.¹ Even so, most retirees drawing a pension plus Social Security and some investment income land in the 22% or 24% bracket.

Was Your Pension Funded With Pre-Tax or After-Tax Money?

This one question decides whether any part of your check escapes taxation.

If your employer funded the entire benefit, or your contributions came out of your paycheck before taxes were calculated, every penny of every payment is ordinary taxable income. The full amount on your Form 1099-R each year flows straight onto your return.² That covers most traditional corporate pensions and many government plans. Check your plan documents or ask your benefits office if you are not sure.

If you did pay in with after-tax dollars, the IRS lets you recover that “investment in the contract” tax-free, spread across your expected retirement.³ Nearly everyone receiving payments from a qualified employee plan, a 403(b), or a qualified employee annuity uses the Simplified Method for this.⁴

Divide your total after-tax contributions by the number of expected payments the IRS assigns based on your age when payments begin:

Age 55 or under: 360 payments
Age 56–60: 310 payments
Age 61–65: 260 payments
Age 66–70: 210 payments
Age 71 or older: 120 payments

Say you contributed $52,000 after-tax and start receiving checks at 63. The IRS assigns 260 expected payments, so $52,000 ÷ 260 = $200 excluded from each month’s payment. If your monthly pension is $3,000, only $2,800 is taxable. That $200 stays fixed regardless of cost-of-living adjustments. Once you recover the full $52,000, every subsequent payment is fully taxable. If you die before recovering the full amount, the unrecovered portion can be claimed as an itemized deduction on your final return.⁴

The Hidden Costs a Pension Can Trigger

The bracket rate on your check is only the start. Pension income raises your adjusted gross income, and higher AGI has knock-on effects that catch many retirees off guard.

More of Your Social Security Becomes Taxable

The IRS uses “provisional income” (AGI plus nontaxable interest plus half your Social Security) to decide how much of your Social Security benefits get taxed. Pension payments feed directly into that number.

For single filers, half of Social Security benefits become taxable once provisional income exceeds $25,000, and up to 85% becomes taxable above $34,000. For married couples filing jointly, the thresholds are $32,000 and $44,000.⁵ These thresholds have not been adjusted for inflation since the 1980s, so a pension of even moderate size typically pushes most retirees into the 85% tier.

Medicare Premium Surcharges (IRMAA)

Medicare Part B and Part D premiums climb at higher income levels through the Income-Related Monthly Adjustment Amount. For 2026, the standard Part B premium is $202.90 per month, but higher-income retirees pay from $284.10 up to $689.90 per month depending on their modified AGI from two years earlier.⁶ A retiree with a $60,000 pension, $30,000 in Social Security, and $25,000 in IRA withdrawals can easily land in the second or third IRMAA tier, adding roughly $1,000 to $2,400 per year in Part B premiums alone. Part D carries a separate surcharge. If a life-changing event like retirement caused the income spike, you can appeal the surcharge with Social Security.

Investment Surcharge and Medical Deductions

Pension income itself is not subject to the 3.8% net investment income tax.⁷ It still counts toward your modified AGI, though, so pension payments can push you past the $200,000 single or $250,000 joint threshold where the 3.8% surcharge applies to your dividends, capital gains, and rental income.⁸

Higher AGI also raises the floor for medical expense deductions. Medical costs must exceed 7.5% of AGI before any deduction kicks in, so at $70,000 AGI, only expenses above $5,250 count.⁹ The larger your pension, the higher that floor climbs.

State Tax on Pension Income

Where you live matters almost as much as how much you collect. Eight states impose no individual income tax, so pension income passes through untouched. Several other states specifically exempt most or all qualified retirement income even while taxing wages. Others tax pensions like ordinary wages at their full rate, and many fall somewhere in between with partial exclusions tied to age or income. The specifics change frequently, so check your state’s current rules each year.

If you move in retirement, federal law protects you from the state you left behind. Under 4 U.S.C. § 114, no state may tax your retirement income once you are no longer a resident there.¹⁰ The law covers distributions from qualified plans, 403(b) plans, governmental plans, and IRAs, for both private-sector and government pensions, so long as the payments come as a series of substantially equal periodic payments or meet other qualifying conditions. Only your current state of residence can tax the pension.

Withholding: Get It Right or Get Penalized

Pension withholding is not automatic in the way wage withholding is. Your pension payer withholds federal income tax based on the instructions you provide on Form W-4P.¹¹ Skip the form and the payer withholds as if you are a single filer with no adjustments, which is often wrong for retirees with multiple income streams. You can also request extra withholding, or opt out by writing “No Withholding” on the form.

The IRS expects payment throughout the year. To avoid an underpayment penalty, you need to meet a safe harbor: pay at least 90% of the current year’s tax, or 100% of last year’s tax.¹² If your prior-year AGI exceeded $150,000, the second safe harbor rises to 110% of the prior year’s tax.¹³ When pension withholding alone will not cover the bill, you can either make quarterly estimated payments in April, June, September, and January, or simply raise the withholding percentage on your W-4P. Bumping the withholding is usually simpler than tracking quarterly estimates.

Lump Sums Are a Different Tax Event

Some plans let you take the entire benefit as a one-time payment instead of monthly checks. A lump sum that is not rolled over is fully taxable as ordinary income in the year you receive it. A $400,000 payout piled onto your other income can push you into the 32% or 35% bracket and generate a six-figure tax bill in one year.

The plan must withhold 20% of any eligible rollover distribution paid directly to you.¹⁴ That is a prepayment, not the final bill. If you are under 59½, the taxable amount also faces a 10% early withdrawal penalty on top of ordinary tax.¹⁵ The penalty does not apply if you leave your employer during or after the year you turn 55 and take distributions from that employer’s plan. Public safety employees in governmental plans qualify at age 50. Distributions from disability or death are also exempt.¹⁶

A direct rollover, where the plan transfers the money electronically to a traditional IRA or another qualified plan, avoids all of this. No withholding, no taxable event, and the money keeps growing tax-deferred.¹⁷ If the plan sends the check to you, you have 60 days to deposit the full distribution amount into a qualifying retirement account, and you have to make up the 20% withheld out of pocket to roll over the full amount.¹⁸ Anything not rolled over within 60 days is a taxable distribution. Request a direct rollover whenever possible.

Divorce, Public Safety, and Survivor Payments

A few situations change who pays the tax or reduce what is owed.

When a pension is divided in a divorce through a Qualified Domestic Relations Order, the former spouse who receives payments reports them as their own income and pays the tax.¹⁹ Any after-tax cost basis is split proportionally between the parties. If a QDRO directs payments to a child rather than a spouse, however, the tax falls on the plan participant.

Retired law enforcement officers, firefighters, rescue squad members, and ambulance crew members can exclude up to $3,000 per year from gross income when their governmental plan pays health or long-term care insurance premiums directly to the insurer.²⁰ The premium payment must go straight from the plan to the insurer. Reimbursing yourself does not qualify. Officers who retired early before normal retirement age are not eligible.

Survivor benefits are taxed as ordinary income to whoever receives them, using the same rules that applied to the original retiree.⁴ If the retiree had a cost basis and had not fully recovered it, the beneficiary keeps excluding the same monthly amount under the Simplified Method until it is used up. A surviving spouse should file a fresh W-4P, since their bracket and total income will not match the deceased retiree’s.
