Federal pensions are taxed as ordinary income by the IRS, but the amount you owe depends on your total income and whether you have other retirement money

A federal pension — whether you worked for the U.S. Postal Service, the Department of Defense, the Social Security Administration, or another federal agency — counts as taxable income. The IRS treats it the same way it treats wages: you owe federal income tax on the full amount you receive each month. However, your actual tax bill depends on your other income sources, your filing status, and whether you're over 65.

The federal government does not automatically withhold taxes from your pension check. You can request withholding when you start receiving your pension, or you can pay estimated taxes quarterly. If you don't arrange either one, you may owe a large bill when you file your tax return.

Key Takeaways

  • Federal pensions are fully taxable income at the federal level, meaning you owe income tax on the entire monthly amount.
  • You can request tax withholding from your pension check, or you can pay estimated taxes yourself — the federal government does not automatically deduct taxes.
  • State income tax on your federal pension varies: some states tax it fully, some tax it partially, and some do not tax it at all.
  • If you have other income sources — Social Security, investments, part-time work — your total income determines your tax bracket and may push you into a higher rate.
  • You can claim the standard deduction or itemize deductions to reduce your taxable income, and you get an extra deduction if you are 65 or older.

How federal pension income is taxed at the federal level

The IRS taxes your federal pension as ordinary income, which means it is added to any other income you have and taxed according to the tax brackets for your filing status. If you are single and your pension is your only income, you pay tax only on the amount above the standard deduction — $14,600 for 2024, or $18,250 if you are 65 or older. If you are married filing jointly, the standard deduction is $29,200, or $36,700 if both spouses are 65 or older.

The tax rate you pay depends on your total income. For example, if you are single, receive a $3,000 monthly federal pension, and have no other income, your annual pension income is $36,000. After subtracting the standard deduction of $14,600, your taxable income is $21,400. In 2024, that puts you in the 12 percent federal tax bracket, so you would owe roughly $2,568 in federal income tax for the year — before any withholding or payments you have already made.

If you have other income — Social Security, investment earnings, part-time work, or a spouse's income — that total is added to your pension. A higher total income can push you into a higher tax bracket. This is why many federal retirees with multiple income sources end up owing more in taxes than they expected.

State income tax on federal pensions varies widely

Whether your federal pension is taxed by your state depends entirely on where you live. Some states do not tax pension income at all. Others tax it fully. Still others tax it partially or only if your total income exceeds a certain threshold.

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

States that tax federal pensions fully include California, Colorado, Connecticut, Delaware, Georgia, Hawaii, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, Vermont, Virginia, West Virginia, and Wisconsin. The state tax rate varies by state and by your income level.

A few states — Arizona, Arkansas, Idaho, and Utah — tax federal pensions only if your total income exceeds a certain amount, or they allow a partial deduction. You can check your state's tax agency website or call them directly to find out the exact rules for your situation.

How to arrange tax withholding from your pension

When you start receiving your federal pension, you should decide whether to have taxes withheld from each check. If you do not request withholding, the full pension amount goes to you, and you are responsible for paying taxes yourself — either by making quarterly estimated tax payments or by paying the full amount when you file your return.

To request withholding, contact your pension-paying agency. For Civil Service Retirement System (CSRS) pensions, contact the Office of Personnel Management. For Federal Employees Retirement System (FERS) pensions, also contact OPM. For military pensions, contact the Defense Finance and Accounting Service. For other federal agencies, ask your benefits office.

You will fill out a W-4P form (Withholding Certificate for Pension or Annuity Payments). On this form, you tell the agency how much tax to withhold from each check. You can choose a flat dollar amount, a percentage of your pension, or an amount based on your total expected income for the year. If your circumstances change — you turn 65, you start receiving Social Security, or you take a part-time job — you can update your W-4P at any time.

Many federal retirees choose to have taxes withheld so they do not face a large bill at tax time. Others prefer to keep the full pension amount and pay estimated taxes quarterly. There is no single right answer; it depends on your cash flow and whether you prefer to have taxes taken out gradually or pay them in larger chunks.

What happens if you do not withhold taxes

If you do not request withholding and do not make quarterly estimated tax payments, you will owe the full amount of tax when you file your return. Depending on how much tax you owe, you may also owe a penalty for underpayment of estimated taxes.

The IRS charges an underpayment penalty if you owe more than $1,000 in taxes for the year and did not pay enough through withholding or estimated payments throughout the year. The penalty is calculated based on the federal interest rate plus 3 percent, and it compounds quarterly. For 2024, the rate is roughly 8 percent per year, though it changes each quarter.

To avoid this penalty, you can either request withholding from your pension or make four quarterly estimated tax payments. If you are unsure how much to pay, a tax professional or the IRS can help you calculate it based on your expected income for the year.

How other income affects your pension tax bill

If you receive Social Security in addition to your federal pension, your tax situation becomes more complex. Social Security is not automatically taxable, but it becomes taxable if your "combined income" exceeds certain thresholds. Combined income is calculated as your adjusted gross income plus nontaxable interest plus half of your Social Security benefits.

For example, if you are single and your combined income is between $25,000 and $34,000, up to 50 percent of your Social Security benefits become taxable. If your combined income exceeds $34,000, up to 85 percent of your Social Security benefits become taxable. For married couples filing jointly, the thresholds are $32,000 and $44,000.

This means that receiving a federal pension can push your combined income high enough to make your Social Security taxable — even though Social Security alone might not have been taxable. This is one reason why federal retirees with multiple income sources should work with a tax professional to understand their full tax picture.

Investment income, part-time work, and rental income also add to your total income and can increase your tax bill. The more income sources you have, the more important it is to plan ahead and arrange withholding or estimated payments.

Deductions and credits that may reduce your tax bill

Even though your federal pension is fully taxable, you can reduce your taxable income by claiming deductions. The simplest route is the standard deduction, which is $14,600 for single filers in 2024, or $18,250 if you are 65 or older. If you are married filing jointly, it is $29,200, or $36,700 if both spouses are 65 or older.

If you have significant deductible expenses — mortgage interest, property taxes, charitable donations, medical expenses — you may benefit from itemizing deductions instead of taking the standard deduction. You can only claim one or the other, so compare the two to see which gives you a larger deduction.

You may also be able to claim tax credits. The Earned Income Tax Credit (EITC) does not apply to pension income, but other credits might. For example, if you have investment income and your income is below certain thresholds, you may may have access to for the Saver's Credit. If you paid tuition for yourself or a dependent, you may may have access to for education credits. A tax professional can review your situation and identify credits you might have missed.

Frequently Asked Questions

Can I avoid paying taxes on my federal pension?

No. Federal pensions are fully taxable income at the federal level, and you cannot exclude them from your tax return. However, you can reduce your taxable income by claiming deductions, and you can reduce your tax bill by claiming credits. Some states do not tax federal pensions, so your state tax bill may be zero even if your federal bill is not.

What if I move to a state that does not tax pensions after I retire?

You will owe no state income tax on your federal pension in that state going forward. However, you may still owe federal income tax. Some states also have residency requirements — you may need to live there for a certain number of days per year to may have access to for the pension tax exemption. Check your new state's tax agency website to confirm the rules.

Do I have to pay taxes on my pension if it is below a certain amount?

You must file a federal tax return if your income is above the filing threshold for your age and filing status. For 2024, a single person under 65 must file if their income is $14,600 or more. If you are 65 or older, the threshold is $18,250. If your pension alone is below these amounts and you have no other income, you may not need to file — but you should check the IRS website or consult a tax professional to be sure.

Can I take a lump-sum payment of my federal pension instead of monthly payments?

Some federal pension plans allow lump-sum payments, but not all. If your plan does, the lump sum is still fully taxable in the year you receive it. You can request withholding on a lump sum, or you can roll it over to an IRA or another retirement account to defer taxes. Ask your pension-paying agency whether a lump-sum option is available and what the tax consequences are.

What if I worked for a federal agency and also have a private pension?

Both pensions are fully taxable at the federal level. Your total income from both pensions is added together and taxed according to your tax bracket. You can request withholding from each pension separately, or you can coordinate withholding across both to ensure you are paying enough tax throughout the year. A tax professional can help you set this up.
