Most pension income is taxable as ordinary income

Yes, you typically owe federal income tax on pension payments. The IRS treats most pension income the same way it treats wages — as ordinary income subject to tax at your regular rate. The amount you owe depends on your total income for the year, your filing status, and whether you have other sources of income like Social Security or investment earnings.

The key exception is if you made after-tax contributions to your pension plan during your working years. Those contributions — the money you put in with dollars you already paid tax on — come back to you tax-free. The growth and employer contributions, however, are taxable. Most people receive a mix of both, so part of each check is taxable and part is not.

State and local taxes on pensions vary widely. Some states tax pension income at the full rate, some tax it at a reduced rate, and a handful do not tax it at all. Where you live in retirement can make a real difference in how much you actually keep.

Key Takeaways

  • Pension payments are taxed as ordinary income at the federal level unless they came from after-tax contributions you made yourself.
  • Your pension plan administrator should send you a 1099-R form each January showing how much is taxable and how much is not.
  • You can have taxes withheld from your pension check each month, or pay estimated taxes quarterly, to avoid owing a large amount at tax time.
  • State and local tax treatment of pensions differs by location — some states do not tax pensions at all, while others tax them fully.
  • If you receive both a pension and Social Security, the combination may push you into a higher tax bracket or make your Social Security taxable.

How the IRS separates taxable from non-taxable pension money

Your pension plan keeps a record of how much you contributed with your own money over your career. When you start receiving payments, the plan uses a formula to figure out what portion of each check represents your own contributions (non-taxable) and what portion represents employer money and investment gains (taxable).

This calculation is called the exclusion ratio. It divides your total after-tax contributions by your expected lifetime benefit payout. If you contributed $50,000 and your plan expects to pay you $200,000 total over your lifetime, roughly 25 percent of each check is non-taxable and 75 percent is taxable. Once you have recovered all your after-tax contributions, every dollar after that is fully taxable.

Your pension administrator reports this breakdown on your Form 1099-R, which you receive by January 31 each year. Box 1 shows the total distribution, and Box 2a shows the taxable amount. You use this form to fill out your tax return. If the plan made an error in the calculation, you can request a corrected form, but the IRS generally trusts the plan's math unless you have documentation proving otherwise.

Withholding taxes from your pension check

You do not have to wait until April to pay taxes on your pension. Most pension plans let you request that they withhold federal income tax directly from each payment. This works the same way withholding worked when you were employed — money comes out of your check before you receive it, and the plan sends it to the IRS on your behalf.

You choose the withholding amount when you start receiving payments, using Form W-4P. You can withhold a flat dollar amount each month, a percentage of each payment, or an amount based on your total expected tax liability for the year. If your circumstances change — you turn 72 and start taking Required Minimum Distributions, or you pick up a part-time job — you can adjust your withholding by submitting a new W-4P.

Withholding is optional, but skipping it often leads to underpayment penalties. If you do not withhold enough and do not pay estimated taxes, the IRS charges interest and a penalty on the shortfall. For most retirees, having the plan withhold is simpler than managing quarterly estimated tax payments on your own.

State and local taxes on pension income

Federal tax is only part of the picture. Your state and sometimes your city or county will also want a share of your pension income — unless they have chosen not to tax it.

A handful of states do not tax pension income at all. These include Florida, Illinois, Mississippi, Pennsylvania, and Tennessee, among others. Some states tax pensions at a reduced rate or only tax pensions above a certain income threshold. A few states tax pensions the same way they tax wages. Your state's tax department website will have a clear answer for your specific situation.

If you moved to a new state after retiring, you may owe taxes to your former state on pension income earned while you lived there, depending on that state's rules. Some states have reciprocal agreements with neighboring states that affect this. The safest approach is to check both your current state's rules and your former state's rules if you moved recently.

What happens when you combine pension with Social Security

If you receive both a pension and Social Security, the combination can push you into a higher tax bracket or make your Social Security benefits taxable — a situation that catches many retirees off guard.

The IRS uses a formula called combined income to determine whether your Social Security is taxable. Combined income includes your adjusted gross income, non-taxable interest, and half of your Social Security benefits. If your combined income exceeds certain thresholds (which vary by filing status), up to 50 or 85 percent of your Social Security becomes taxable. A pension payment that seems modest on its own can tip you over that threshold when added to Social Security.

This is one reason to think carefully about the order in which you claim benefits. If you can delay your pension or Social Security by a year or two, you might lower your combined income in earlier years and reduce your tax burden. A tax professional can model different scenarios for your specific situation.

Required Minimum Distributions and taxes

If your pension is held in a traditional IRA or a 401(k) rather than a company pension plan, you must begin taking Required Minimum Distributions (RMDs) starting the year you turn 73 (as of 2023; this age has been rising gradually). The IRS calculates the minimum amount you must withdraw each year based on your age and account balance. You cannot avoid this withdrawal, and you owe income tax on the full amount withdrawn.

RMDs are calculated using IRS life expectancy tables and your account balance on December 31 of the prior year. If you have multiple retirement accounts, you can aggregate them for the RMD calculation but must withdraw from each account separately. If you miss an RMD or withdraw too little, the IRS charges a penalty of 25 percent of the shortfall (reduced to 10 percent if you correct it within two years).

Some people use RMDs to fund charitable donations or other financial goals. Others try to minimize the tax impact by spreading withdrawals across the year or coordinating them with lower-income years. Your financial advisor or tax preparer can help you plan RMDs in a way that fits your overall tax situation.

Frequently Asked Questions

Can I avoid paying taxes on my pension by rolling it into an IRA?

Rolling a pension into an IRA does not avoid taxes — it only delays them. You still owe income tax when you withdraw the money. The advantage of a rollover is flexibility: you control when and how much you withdraw (subject to RMDs after age 73), and you may have more investment options. The tax liability itself does not change.

What if I worked for a government employer and have a government pension?

Government pensions follow the same federal tax rules as private pensions. However, some states exempt government pensions from state income tax while taxing private pensions, or vice versa. Check your state's specific rules. Federal employees may also be subject to the Government Pension Offset, which affects Social Security benefits, though this is a separate issue from income tax.

Do I owe taxes on a pension I receive as a surviving spouse?

Yes, survivor pensions are taxable income to the person receiving them. The same rules apply: you receive a 1099-R, part may be non-taxable if the original employee made after-tax contributions, and you can request withholding. Some states offer tax breaks for survivor benefits, so check your state's rules.

What if my pension is very small — do I still have to report it?

Yes. If you receive a 1099-R, you must report it on your tax return regardless of the amount. The IRS matches 1099-Rs to tax returns, so not reporting it will trigger a notice. Even if the amount is small enough that you would not otherwise owe tax, you still need to file and report the income.

Can I deduct pension contributions I made while working?

If you made after-tax contributions (contributions from money you already paid tax on), those are not deductible — you already got no deduction when you paid them. If you made pre-tax contributions through a 401(k) or similar plan, you got the deduction when you made them. You cannot deduct them again on your current tax return.
