Most pension income is taxed as ordinary income, but the amount you pay depends on how much you receive, your other income, and whether your pension was funded with pre-tax or after-tax dollars.

When you start drawing a pension, the IRS treats it like wages for tax purposes. If your pension came from contributions your employer made before taxes were taken out — which is true for most traditional pensions — you owe federal income tax on the full amount you receive each month. Some states also tax pension income, though a growing number exempt it entirely.

The tax you actually pay is determined by your tax bracket, which depends on your total income for the year. If your pension is your only income and it's modest, you might owe little or nothing. If you have a pension plus Social Security, investment income, or other earnings, your tax bill rises because you're in a higher bracket.

Key Takeaways

  • Traditional pensions are taxed as ordinary income at your federal tax rate, which depends on your total yearly income.
  • If your pension was funded with after-tax contributions, only the earnings portion is taxed; the contributions themselves are not.
  • Some states do not tax pension income at all, while others tax it fully; a few offer partial exemptions based on age or income.
  • You can request that your pension administrator withhold taxes from each payment, or you can pay estimated taxes quarterly to avoid penalties.
  • Withdrawals before age 59½ from certain pension plans may trigger a 10 percent early withdrawal penalty on top of income tax.

How the IRS taxes traditional pensions

A traditional pension is funded by your employer using pre-tax dollars. Because you never paid income tax on that money when it was contributed, the IRS taxes you when you receive it. This is straightforward: if your pension pays you $2,000 per month, that $2,000 is added to your other income for the year, and you pay tax on the combined total.

Your tax rate depends on your tax bracket. For 2024, a single person with $40,000 in total income falls into the 12 percent federal bracket, while someone with $100,000 falls into the 22 percent bracket. Your pension pushes you into whichever bracket your total income reaches. If you have a $30,000 pension and $20,000 from part-time work, you owe tax on $50,000 combined.

The IRS requires your pension administrator to withhold federal income tax from each payment unless you file a Form W-4P requesting otherwise. The withholding is an estimate based on your marital status and the number of allowances you claim. If too much is withheld, you get a refund when you file your tax return. If too little is withheld, you owe when you file.

Pensions funded with after-tax contributions

If you contributed your own money to your pension — money you already paid income tax on — that portion is not taxed again. Only the earnings and employer contributions are taxable. This is less common in traditional pensions but does occur in some plans.

To calculate the taxable portion, you and your pension administrator use the simplified method or the general rule, depending on your situation. The simplified method divides your total contributions by your life expectancy (using IRS tables) to determine how much of each payment is non-taxable return of contribution. The rest is taxable income. Your pension statement should show this breakdown, or you can request it from the administrator.

State income tax on pensions

Federal tax is only part of the picture. Your state may also tax your pension, and the rules vary widely. Some states — including Florida, Texas, Pennsylvania, and Illinois — do not tax pension income at all. Others tax it fully as ordinary income. A third group offers partial exemptions, often based on your age or income level.

If you live in a state that taxes pensions, your pension administrator may withhold state tax automatically, or you may need to arrange it yourself. If you move to a different state after you start receiving a pension, the tax treatment can change. Some states tax pensions only if you were a resident when you retired; others tax based on where you live now. Check your state's tax authority website or ask your pension administrator which rules apply to you.

Withholding and estimated taxes

Your pension administrator withholds federal income tax by default, but you can change this by filing a new Form W-4P at any time. You might request lower withholding if you have other income sources that already cover your tax liability, or higher withholding if you want to avoid owing money at tax time.

If your withholding is too low and you end up owing more than $1,000 when you file your return, you may owe a penalty for underpayment of estimated taxes. To avoid this, you can either increase withholding from your pension or make quarterly estimated tax payments directly to the IRS using Form 1040-ES. Many retirees find it simpler to adjust withholding once and let the pension administrator handle it automatically.

Early withdrawal penalties and special situations

If you withdraw money from a pension plan before age 59½, you typically owe a 10 percent early withdrawal penalty on top of regular income tax. This applies to most employer-sponsored plans and IRAs. However, some pensions allow substantially equal periodic payments (SEPP), which let you withdraw before 59½ without the penalty if you follow strict rules about the amount and frequency.

If you receive a lump-sum distribution — the entire pension paid out at once rather than monthly — you have the option to roll it into an IRA or another may have access to plan within 60 days to defer taxes. If you do not roll it over, the entire amount is taxable in that year, and you may owe the 10 percent penalty if you are under 59½. Some plans allow a partial rollover, which lets you defer part of the distribution and take the rest as taxable income.

How to plan for pension taxes

Before you start receiving your pension, ask your administrator for a projection showing your monthly payment and the estimated tax withholding. Then add up all your other expected income for the year — Social Security, part-time work, investment income, rental income — to see your total tax picture. This helps you decide whether the default withholding is enough or whether you need to adjust it.

If you are still working when you start your pension, your combined income may push you into a higher tax bracket than you expect. If you have a spouse with significant income, their earnings affect your joint tax bracket too. A tax professional or your CPA can model different scenarios and help you decide on withholding and estimated tax payments. This planning is especially important if you are taking a lump-sum distribution or rolling money between accounts.

Frequently Asked Questions

Do I have to pay taxes on my entire pension payment?

You pay federal income tax on the full amount unless part of your pension came from after-tax contributions you made yourself. If you contributed after-tax money, only the employer contributions and earnings are taxed. Your pension statement should show the breakdown, or you can request it from your administrator.

What happens if my pension withholding is too low?

You will owe the difference when you file your tax return. If you owe more than $1,000, you may also owe an underpayment penalty. You can avoid this by increasing withholding on Form W-4P or by making quarterly estimated tax payments to the IRS.

Can I defer taxes on a lump-sum pension payment?

Yes. If you receive your entire pension at once, you can roll it into a traditional IRA or another may have access to retirement plan within 60 days to defer taxes. If you do not roll it over, the full amount is taxable in that year, and you may owe a 10 percent early withdrawal penalty if you are under 59½.

Does my state tax my pension?

It depends on your state. Some states do not tax pensions at all, while others tax them as ordinary income. A few offer exemptions based on age or income. Check your state's tax authority website or ask your pension administrator which rules apply to you.

How do I know what tax bracket my pension puts me in?

Add your pension income to all other income you expect that year — Social Security, wages, investment income, and so on. Look up the 2024 tax brackets for your filing status on the IRS website. Your combined income determines your bracket and your tax rate.
