Most pensions are taxable income, but the amount you pay depends on how you contributed and when you withdraw

Whether you owe tax on a pension withdrawal depends on two things: whether you paid tax on the money when it went into the plan, and what type of pension you have. If your employer put money into a traditional pension and you did not pay tax on it at the time, you will owe federal income tax on the full amount you withdraw. If you contributed your own after-tax dollars, only the earnings portion is taxed. Some pensions — mainly military and certain government pensions — have different rules.

The IRS treats pension income like regular income. It gets added to your other income for the year, and you pay tax at your ordinary rate. You do not get a special tax break just because the money came from a pension. If you withdraw a large amount in one year, you may move into a higher tax bracket and owe more.

Key Takeaways

  • Traditional pensions funded by your employer are fully taxable when you withdraw them, because you did not pay tax on the contributions when they were made.
  • If you contributed your own after-tax money to a pension, you pay tax only on the growth and earnings, not on your original contributions.
  • Pension income is taxed as ordinary income at your regular tax rate, not at a special lower rate.
  • Your employer or pension administrator will send you a Form 1099-R each year showing how much you withdrew and how much is taxable.
  • Some military pensions and federal employee pensions have partial tax exclusions that reduce your taxable amount.

Traditional pensions and how they are taxed

A traditional pension is money your employer set aside for you during your working years. Your employer made contributions on your behalf, and those contributions were not counted as income to you at the time. Because you never paid tax on that money, the IRS taxes it when you take it out.

When you start receiving pension payments, your employer or the pension plan administrator sends you a Form 1099-R each year. This form shows the total amount you received and breaks down how much is taxable. You report this amount on your federal tax return, usually on Form 1040. The taxable amount gets added to any other income you have that year — wages, Social Security, interest, or other pensions.

If you worked for multiple employers and have more than one pension, each one sends its own Form 1099-R. You report all of them. The total pension income you report determines your tax bracket for the year.

Pensions you funded yourself with after-tax money

If you made contributions to a pension plan using money you had already paid income tax on, those contributions are not taxed again when you withdraw them. Only the earnings — the growth and interest the money earned while it sat in the plan — are taxable.

Your pension administrator should track how much of your balance came from your own contributions versus employer contributions and earnings. When you withdraw money, the Form 1099-R will show a breakdown. The taxable portion is usually listed separately from the non-taxable portion. You only report the taxable part on your return.

If the form does not clearly separate the two, contact the pension administrator and ask for a breakdown. You need this to report correctly and avoid paying tax twice on the same money.

Military pensions and federal employee pensions

Military pensions have a partial tax break. If you retired from the military, you can exclude up to $3,000 per year of military pension income from your taxable income. This exclusion applies only to you — not to a surviving spouse who receives the pension after your death, unless you elected a specific survivor benefit option.

Federal employees who retired under the Civil Service Retirement System (CSRS) can exclude a portion of their pension based on how much they contributed. The exclusion is calculated using a formula that compares your contributions to your total pension. Employees who retired under the Federal Employees Retirement System (FERS) do not get this exclusion — their pensions are fully taxable like traditional pensions.

If you receive a military or federal pension, your Form 1099-R should show the taxable and non-taxable amounts already calculated. If it does not, contact the pension administrator to confirm the correct breakdown before you file.

Lump-sum pension payments and tax withholding

Some pensions offer a lump-sum option: instead of receiving monthly payments for life, you take the entire balance in one payment. This creates a large taxable event in a single year. If the amount is substantial, you may owe significantly more tax that year because you move into a higher tax bracket.

When you receive a lump sum, your pension administrator is required to withhold federal income tax. The withholding rate depends on whether the payment is a direct rollover to another retirement account or a distribution paid to you. If it is paid directly to you, the administrator typically withholds 20 percent. You can request a different withholding amount on Form W-4P, but you must do this before the payment is made.

If the withholding is not enough to cover your actual tax bill, you will owe the difference when you file your return. If too much was withheld, you get a refund. Keep the Form 1099-R you receive — you will need it to report the income correctly.

Pension income and Social Security taxation

If you receive both a pension and Social Security, the pension income can affect how much of your Social Security is taxable. The IRS uses a calculation called combined income that includes your adjusted gross income, non-taxable interest, and half of your Social Security benefits. If this combined income exceeds certain thresholds, up to 85 percent of your Social Security becomes taxable.

This means a large pension withdrawal in a particular year could push you over the threshold and cause more of your Social Security to be taxed. If you know you will have a large withdrawal coming, you might consider spreading it over multiple years if your pension plan allows it, or planning the timing with a tax professional.

Reporting pension income on your tax return

Pension income goes on Form 1040, line 5a (or line 5b if it is taxable). You will receive a Form 1099-R from your pension administrator by January 31 of the year after you receive the payment. The form shows the gross distribution in box 1 and the taxable amount in box 2a. If box 2a is blank or shows "unknown," the administrator did not calculate it, and you may need to do the calculation yourself or ask them to provide it.

If you received a lump-sum distribution and rolled it over to an IRA or another may have access to retirement plan within 60 days, that rollover is not taxable. You report it differently — usually on Form 1040 line 4 as a rollover contribution. Keep documentation of the rollover, including the date you received the money and the date you deposited it into the new account.

If you are unsure whether your pension is fully taxable, partially taxable, or non-taxable, contact your pension administrator before you file. Getting this wrong can result in underpayment penalties or an audit.

State income tax on pensions

Federal tax is only part of the picture. Many states also tax pension income, though the rules vary widely. Some states do not tax pensions at all. Others tax all pensions the same way the federal government does. A few states offer partial or full exclusions for certain types of pensions — military pensions, government pensions, or pensions from certain employers.

Your pension administrator may withhold state income tax if you request it, but you need to know your state's rules to make sure enough is withheld. If you moved to a different state after you retired, you may owe tax to your new state of residence, not the state where you worked. Check your state's tax agency website or contact them directly to learn how your specific pension is taxed in your state.

Frequently Asked Questions

Do I have to pay tax on my entire pension, or just part of it?

It depends on how the pension was funded. If your employer contributed all the money and you did not pay tax on it when it was contributed, the entire amount is taxable. If you contributed your own after-tax money, only the earnings portion is taxable. Your Form 1099-R should show the taxable amount, but if it does not, contact your pension administrator for a breakdown.

What if I take my pension as a lump sum instead of monthly payments?

The entire lump sum is taxable in the year you receive it, which can push you into a higher tax bracket. Your pension administrator will withhold 20 percent for federal tax unless you request a different amount. You may owe more tax when you file, or you might get a refund if too much was withheld. If you roll the money into an IRA within 60 days, it is not taxable.

Can I avoid paying tax on my pension?

No. Pension income is taxable income. However, you may be able to reduce the amount you owe by rolling a lump sum into a traditional IRA, by timing large withdrawals across multiple years if your plan allows it, or by taking advantage of exclusions if you have a military or federal pension. A tax professional can help you plan withdrawals to minimize your tax bill.

Will my pension affect my Social Security benefits?

Pension income does not reduce your Social Security payment amount, but it can affect how much of your Social Security is taxable. If your combined income (which includes pension income) exceeds certain thresholds, up to 85 percent of your Social Security becomes subject to federal income tax. This can significantly increase your total tax bill.

Do I need to pay estimated taxes on my pension?

If your pension administrator is withholding enough federal tax, you may not need to pay estimated taxes. If withholding is too low or you have other income, you might owe estimated taxes quarterly. Check your withholding by using the IRS Withholding Estimator tool on IRS.gov, or contact a tax professional to review your situation.
