Yes, in almost every case you have to pay taxes on your pension. Payments from a traditional employer pension are treated as ordinary income at the federal level and taxed at the same rates as wages, because most pensions were funded with pre-tax dollars.1Internal Revenue Service. Topic No. 410, Pensions and Annuities How much you actually owe depends on three things: whether any of the money going in was already taxed, what other income you have alongside the pension, and what state you live in.
How Much Federal Tax You’ll Owe
Your plan administrator sends you a Form 1099-R each January showing the total distribution and the portion the IRS considers taxable.2Internal Revenue Service. Instructions for Forms 1099-R and 5498 That taxable amount stacks on top of any other income and gets taxed at your marginal rate.
For 2026, the ordinary-income brackets are:
- 10% up to $12,400 single / $24,800 married filing jointly
- 12% up to $50,400 / $100,800
- 22% up to $105,700 / $211,400
- 24% up to $201,775 / $403,550
- 32% up to $256,225 / $512,450
- 35% up to $640,600 / $768,700
- 37% above those thresholds
Those brackets apply to income after deductions. The 2026 standard deduction is $16,100 for a single filer and $32,200 for a joint return, and anyone 65 or older gets an additional $6,000 senior deduction on top of that. A married couple both over 65 can shield up to $44,200 before any federal tax applies.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 20264Internal Revenue Service.

When Part of Your Pension Comes Back Tax-Free
If you contributed after-tax dollars to the pension during your working years, you have a “cost basis” in the plan. A slice of each monthly check is a tax-free return of that basis, and only the rest is taxable.
For most qualified employer pensions, the IRS uses the Simplified Method. You divide your total after-tax contributions by a number of expected payments tied to your age when payments began. Start at 65 on a single-life annuity, and the table assigns 240 expected payments. That fixed dollar amount comes off each check as tax-free until you’ve fully recovered your basis. After that, every payment is fully taxable.5Internal Revenue Service. Publication 575 (2025), Pension and Annuity Income
If none of your contributions were after-tax, the entire payment is taxable. That is the default for most private-sector pensions.
Lump Sum or Monthly Payments
Taking your pension as a lump sum changes the tax picture in two important ways.
First, if the check comes to you rather than going directly into another retirement account, the plan is required to withhold 20% for federal income tax.1Internal Revenue Service. Topic No. 410, Pensions and Annuities You have 60 days to deposit the money into an IRA to avoid tax, but to keep the whole amount tax-deferred you’d need to replace that withheld 20% out of your own pocket and wait to get it back as a refund.
Second, a large one-year distribution can push you into a much higher bracket than a monthly payout ever would. A direct rollover to an IRA sidesteps both problems: no withholding, no taxable event, and you draw from the IRA on your own schedule.6eCFR. 26 CFR 31.3405(c)-1 – Withholding on Eligible Rollover Distributions Any after-tax portion of the lump sum comes back to you tax-free either way.
The 10% Penalty for Payments Before 59½
If you start pulling pension money before age 59½, you generally owe an extra 10% tax on the taxable portion in addition to regular income tax.7Office of the Law Revision Counsel. 26 U.S. Code 72 The penalty is reported on Form 5329.
Several situations exempt you from the 10%:
- Leaving the employer during or after the year you turn 55 (age 50 for qualifying public safety workers), for distributions from that employer’s plan
- A series of substantially equal periodic payments under Rule 72(t)
- Total and permanent disability
- Payments to an ex-spouse under a qualified domestic relations order
- Unreimbursed medical expenses above 7.5% of adjusted gross income
- Up to $5,000 per child for a qualified birth or adoption8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Watch the age-55 rule carefully. It only applies to the plan of the employer you actually separated from. If you rolled that pension into an IRA and then retire at 56, the IRA distribution still gets the 10% penalty because the IRA exception requires 59½.
How Your Pension Can Make Your Social Security Taxable
This is the piece most retirees don’t see coming. Your pension counts toward the “provisional income” calculation that decides whether Social Security benefits get taxed. Provisional income is your adjusted gross income plus tax-exempt interest plus half your Social Security.
Cross $25,000 single or $32,000 joint, and up to 50% of your Social Security becomes taxable. Cross $34,000 or $44,000, and up to 85% is taxable.9Internal Revenue Service. Social Security Income Those thresholds have not been adjusted since 1984, so a typical retiree with a pension of any size plus Social Security lands in the 85% zone. A $30,000 pension, $20,000 in Social Security, and a bit of interest income is more than enough to get there. There is no way to opt out; the only lever is timing when you recognize other income.
How a Pension Can Raise Your Medicare Premium
Pension income also flows into the modified adjusted gross income (MAGI) that Medicare uses to set your Part B and Part D premiums. If your MAGI clears $109,000 single or $218,000 joint in 2026, an Income-Related Monthly Adjustment Amount (IRMAA) is added to your premium two years later.10Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
A single-year lump sum is the classic IRMAA trap. Take $200,000 from a pension in one year, and two years later Medicare bills you as though that’s your normal income, even though it isn’t. A direct rollover to an IRA avoids the spike because it isn’t a taxable event.
State Taxes Vary Widely
Nine states charge no income tax at all, which automatically exempts pension income. A few others tax wages but specifically exempt qualified pension distributions; Illinois, Mississippi, and Pennsylvania are examples. Most remaining states tax pensions like wages, though many offer partial exclusions that phase out at higher incomes or apply only to government and military pensions. Check with your state revenue department before assuming, particularly if you’re considering a move, because property and sales taxes can offset a lack of income tax.
Making Sure Enough Tax Gets Withheld
Pension administrators don’t automatically withhold the right amount, and the default often leaves retirees short at filing time. You control federal withholding on periodic payments by filing Form W-4P with the plan; lump sums and other nonperiodic payments use Form W-4R instead.11Internal Revenue Service. Form W-4P (2026)12Internal Revenue Service. About Form W-4R
If withholding won’t cover the bill, you’ll need quarterly estimated payments using Form 1040-ES. The 2026 due dates are April 15, June 15, September 15, and January 15, 2027.13Internal Revenue Service. 2026 Form 1040-ES To avoid an underpayment penalty, your combined withholding and estimated payments need to hit the safe harbor: 90% of this year’s tax or 100% of last year’s (110% if your prior-year AGI topped $150,000).14Internal Revenue Service. Publication 505 (2025) The cleanest option for most retirees is to raise the W-4P withholding enough to cover Social Security taxation and any other income, and skip quarterly filings.
Pensions That Don’t Follow the Standard Rules
A few types of retirement income are treated differently, so it’s worth knowing where your money actually falls.
VA disability compensation is completely tax-free and doesn’t have to be reported. Military retirement pay based on years of service, on the other hand, is taxed as ordinary income like any other pension.15Internal Revenue Service. Veterans Tax Information and Services
Railroad Retirement benefits are split. The Social Security Equivalent Benefit portion of Tier I follows the same provisional-income rules as Social Security. The rest of Tier I and all of Tier II are taxed as regular pension income.16Internal Revenue Service. Topic No. 423, Social Security and Equivalent Railroad Retirement Benefits
Non-qualified annuities bought with after-tax money work the opposite of a pension: only the earnings portion of each payment is taxable, and the return of your original investment is tax-free.
If you’re receiving pension money as a surviving spouse or beneficiary, the income is generally taxed the same way the participant would have been taxed, though the schedule for withdrawing an inherited account depends on your relationship to the deceased and follows separate rules worth reviewing on their own.17Internal Revenue Service.
