Most pensions are taxable income, but the amount you owe depends on how you funded the pension and when you started withdrawing

Whether you pay tax on a pension comes down to one question: did you or your employer pay the contributions with pre-tax dollars? If yes, the money you withdraw is taxable as ordinary income. If you contributed after-tax dollars, only the earnings on those contributions are taxed — not your original contributions themselves.

The IRS treats pensions the same way it treats other retirement accounts. Money that went in untaxed comes out taxed. Money that went in already taxed does not get taxed again. Your pension provider sends you a Form 1099-R each January showing how much you withdrew and how much is taxable, but you still need to report it on your tax return.

The tax rate you pay is your ordinary income tax rate — the same rate you would pay on wages. If you are in the 22 percent federal bracket, your pension income is taxed at 22 percent. Some states also tax pensions, though a handful exempt them entirely. Your state matters as much as your federal bracket.

Key Takeaways

  • Pensions funded with pre-tax contributions are fully taxable when you withdraw them; pensions funded with after-tax contributions are taxed only on the earnings portion.
  • You report pension income on your federal tax return using the Form 1099-R your pension provider sends you, and you pay tax at your ordinary income tax rate.
  • Some states do not tax pensions at all, while others tax them like any other income, so your state of residence affects your total tax bill.
  • If you withdraw a pension before age 59½, you may owe a 10 percent early withdrawal penalty on top of ordinary income tax, with limited exceptions.

How the IRS decides what portion of your pension is taxable

The IRS uses a formula called the exclusion ratio to determine how much of each pension payment is tax-free. This applies only if you made after-tax contributions to your pension — contributions you paid with money you had already paid income tax on.

The exclusion ratio divides your total after-tax contributions by the total amount the IRS expects you to receive over your lifetime. If you contributed $50,000 after-tax and the IRS calculates you will receive $200,000 total, your exclusion ratio is 25 percent. That means 25 percent of each payment is tax-free, and 75 percent is taxable.

Your pension provider calculates this for you and reports it on your Form 1099-R. You do not calculate it yourself. The form shows the taxable amount in Box 2a, and that is the number you report on your tax return. If your pension was entirely funded with pre-tax dollars, Box 2a will show the full amount you withdrew.

Reporting pension income on your federal return

You report pension income on Form 1040 (the main federal income tax form) on the line for pensions and annuities. Your pension provider sends you a Form 1099-R by January 31 each year showing the amount withdrawn and the taxable portion. You use the numbers from that form — you do not estimate or recalculate.

If you receive multiple pensions, you get a separate Form 1099-R for each one. Add all the taxable amounts together and report the total on your return. If you are filing electronically, the software walks you through entering this information. If you are filing by hand, the Form 1040 instructions show exactly where the number goes.

Some people owe estimated tax payments on pension income if the pension provider did not withhold enough tax. If you know your pension will push you into a higher bracket or you are receiving a large lump sum, you can ask your pension provider to withhold extra tax from each payment. This is done on Form W-4P, which your pension provider can mail or email to you.

State income tax on pensions varies widely

Federal tax is only part of the picture. Your state may tax your pension, may exempt it entirely, or may tax it only under certain conditions. This varies significantly by state and can change year to year.

States that do not tax pension income at all include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe no state income tax on your pension, though you still owe federal tax.

Most other states tax pensions as ordinary income. Some states offer partial exemptions based on age or income level — for example, taxing pensions only if your total income exceeds a certain threshold, or exempting pensions for people over 65. A few states tax only pensions from government employers, not private pensions. You need to check your specific state's rules, which you can find on your state revenue department's website or by contacting them directly.

The 10 percent early withdrawal penalty and when it applies

If you withdraw from a pension before age 59½, you normally owe a 10 percent early withdrawal penalty on top of ordinary income tax. This is a federal penalty, separate from the tax itself. If you withdraw $10,000 early, you owe 10 percent of that ($1,000) as a penalty, plus income tax on the full $10,000.

However, several exceptions exist. You do not owe the penalty if you are withdrawing under the Rule of 55 — a rule that lets you withdraw from a pension or 401(k) without penalty if you separated from service (left your job) in the year you turned 55 or later. You also avoid the penalty if you are withdrawing due to disability, if you are receiving distributions as part of a may have access to domestic relations order (a court order related to divorce), or if you are taking substantially equal periodic payments under IRS rules.

The Form 1099-R your pension provider sends shows whether the 10 percent penalty applies. If it does, the penalty amount appears in Box 4. You report this on your tax return, and it increases your total tax bill. If you think an exception applies to you, contact your pension provider before withdrawing — they can often process the withdrawal in a way that avoids the penalty.

Lump sum distributions and special tax treatment

Some pensions offer the option to take your entire balance at once as a lump sum distribution rather than receiving monthly payments for life. A lump sum is fully taxable in the year you receive it, and the amount can be large enough to push you into a higher tax bracket.

If your lump sum qualifies as a may have access to rollover distribution, you have the option to roll it into an IRA or another retirement plan within 60 days without owing tax on it when ready. This postpones the tax bill until you withdraw from the IRA later. Your pension provider can explain whether your lump sum qualifies and how to execute a rollover.

Some older pensions allow forward averaging, a special calculation that lets you spread the tax on a lump sum over multiple years even though you received it all at once. This is rare and applies only to certain pensions from before 1974. If your pension provider mentions this option, ask them to calculate your tax both ways so you can see which is better for your situation.

Frequently Asked Questions

Do I have to pay tax on my pension if I am retired and have no other income?

Yes. Pension income is taxable income regardless of whether you have other income. However, if your pension is your only income and it is below the standard deduction for your age and filing status, you may not owe federal tax. For 2024, the standard deduction is higher for people 65 and older. Check the IRS website or use the interactive tax assistant to see if you must file.

What if my pension provider did not withhold enough tax and I owe money at tax time?

You can ask your pension provider to increase the withholding on future payments using Form W-4P. You can also make estimated tax payments to the IRS quarterly. If you owe a large amount, the IRS allows you to set up a payment plan. Contact the IRS at 1-800-829-1040 or visit IRS.gov to learn about payment options.

Can I deduct pension contributions from my taxable income?

No. If your pension was funded with pre-tax contributions, that deduction was taken when the money went into the pension, not when you withdraw it. If you made after-tax contributions, you already paid tax on that money, so you do not deduct it again. The exclusion ratio ensures you are not taxed twice on the same dollars.

Is my military or government pension taxed differently than a private pension?

Federal tax treatment is the same: pre-tax contributions are taxed on withdrawal, after-tax contributions are not. However, some states exempt military pensions or government pensions from state income tax while taxing private pensions. Check your state's rules to see if your specific pension type qualifies for an exemption.

What happens to my pension if I die before I withdraw all of it?

This depends on your pension plan and the beneficiary option you chose. If you selected a survivor benefit, your beneficiary receives payments and pays tax on the taxable portion just as you would. If you chose a single-life pension with no survivor benefit, the remaining balance stays with the pension plan. Review your pension documents or contact your pension provider to confirm what you chose.
