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

Whether you owe federal income tax on your pension depends on two things: whether you or your employer paid for it with pre-tax dollars, and whether you've already paid tax on those contributions. If your employer contributed to the pension using money before taxes were taken out — the most common setup — you will owe federal income tax on the full amount you receive each month. If you contributed your own after-tax dollars to the pension, only the growth and earnings are taxable, not your original contributions.

State income tax on pensions varies widely. Some states tax pensions the same as federal income tax does. Others exempt military pensions, teacher pensions, or all pension income above a certain age. A few states don't tax income at all. You need to check your specific state's rules, because where you live when you start taking the pension matters more than where you worked.

Key Takeaways

  • Pensions funded with pre-tax employer contributions are fully taxable as ordinary income at the federal level.
  • If you contributed after-tax dollars to your pension, you pay tax only on the earnings and growth, not on what you put in.
  • State tax on pensions ranges from no tax at all to full income tax, and some states have special rules for military or government pensions.
  • Your pension provider should send you a Form 1099-R each January showing how much is taxable and how much is not.
  • You can ask your pension administrator to withhold taxes from each payment, which prevents a large tax bill when you file.

How pre-tax and after-tax contributions change what you owe

Most traditional pensions are funded entirely by your employer using pre-tax dollars — money that was never taxed when it went into the plan. Because you never paid tax on that money when you earned it, you pay tax on it when you take it out. This is called a may have access to pension, and the IRS treats the full monthly payment as taxable income.

If you contributed your own money to the pension — which some older pension plans allowed — the situation splits. The portion you contributed with after-tax dollars is not taxed again when you withdraw it. Only the employer's contributions and all the investment growth are taxable. Your pension statement or the Form 1099-R you receive should show how much of each payment is taxable and how much is a return of your own contributions.

A small number of pensions are funded entirely with after-tax money. These are rare and usually come from specific union contracts or government plans. If this is your situation, your pension administrator will tell you explicitly, because it changes your entire tax picture.

Federal income tax withholding and what happens if you don't withhold

When you start receiving a pension, the pension administrator asks whether you want federal income tax withheld from each payment. If you say yes, they calculate an estimate based on your total annual pension and withhold that amount each month. This is the same withholding that happens with a paycheck — it reduces what you owe when you file your tax return in April.

If you choose not to withhold, or if the withholding is too low, you may owe a large amount when you file. The IRS can also charge you a penalty for underpayment if you owe more than a certain threshold. Most people find it simpler to have taxes withheld, because it spreads the cost across the year instead of creating a surprise bill.

You can change your withholding election at any time by contacting your pension administrator. If you have other income — from a job, Social Security, or investments — you may need to adjust the withholding to account for that. The IRS provides a withholding calculator on its website to help you estimate what you should have withheld.

State income tax on pensions varies by where you live

Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividends and interest, not wages or pensions). If you move to one of these states after you start receiving a pension, you will owe no state tax on it, regardless of where you worked.

Other states tax pensions as ordinary income, meaning you pay the same state tax rate on your pension as you would on wages. Still others offer partial exemptions. Illinois and Mississippi exempt all pension income. Pennsylvania taxes only private pensions, not government or military ones. Some states exempt pensions for people over a certain age — often 59½ or 62 — or cap the amount of pension income that is taxable.

The state where you live when you start taking the pension is usually the one that taxes it, even if you worked in a different state. If you are considering moving in retirement, check that state's pension tax rules before you move, because the difference can be substantial.

Military and government pensions have different rules in some states

Federal military pensions are taxable at the federal level like any other pension. However, many states exempt military pensions from state income tax entirely, even if they tax civilian pensions. This is one of the few areas where the type of pension matters for state tax purposes.

Government employee pensions — from teachers, police, firefighters, and other public workers — are also federally taxable. Some states exempt these as well, while others tax them fully. A few states have a middle ground: they exempt government pensions up to a certain amount or for people over a certain age.

If you receive a military or government pension, ask your pension administrator or your state tax authority whether your state offers an exemption. The rules are specific enough that a quick phone call can save you hundreds of dollars a year.

Social Security and pension income combined can trigger additional tax

If you receive both a pension and Social Security, the combination can push some of your Social Security into taxable income. This happens because the IRS uses a formula called combined income that adds your adjusted gross income, your non-taxable interest, and half of your Social Security benefits. If that total exceeds certain thresholds — $25,000 for single filers and $32,000 for married filing jointly — up to 85 percent of your Social Security becomes taxable.

This is separate from the tax you already owe on the pension itself. It means that adding a pension to Social Security income can increase your total tax bill by more than the pension amount alone would suggest. If you are in this situation, you may want to adjust your withholding or make estimated tax payments to avoid a large bill at tax time.

Form 1099-R tells you what is taxable and what is not

Each January, your pension provider sends you a Form 1099-R, which reports how much pension income you received in the previous year and how much of it is taxable. Box 1 shows the total distribution. Box 2a shows the taxable amount. If you contributed after-tax dollars, Box 3 may show a non-taxable portion.

The form also shows in Box 7 what type of distribution it is — usually code "7" for a regular pension payment. If you took a lump sum or made an early withdrawal, the code will be different and may trigger additional tax or penalties.

You use the information on Form 1099-R to fill out your tax return. If you received multiple pensions, you will receive multiple forms. Keep these forms with your tax records for at least three years in case the IRS has questions.

Early withdrawal penalties and exceptions

If you withdraw money from a pension before age 59½, you normally owe a 10 percent early withdrawal penalty on top of regular income tax. However, pensions have different rules than other retirement accounts. Most traditional pensions do not allow early withdrawal at all — you must wait until the plan's stated retirement age, which is often 55, 62, or 65 depending on the plan.

Some pensions allow a Rule of 55 exception: if you separate from service in the year you turn 55 or later, you can withdraw without the 10 percent penalty, though you still owe income tax. A few pensions allow hardship withdrawals or loans, but these are uncommon and have strict rules.

If you are considering an early withdrawal, contact your pension administrator first to find out whether it is even possible and what the tax consequences will be. The rules are specific to each plan.

Frequently Asked Questions

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

If your employer funded the pension with pre-tax dollars — which is standard — you pay federal income tax on the full amount. If you contributed after-tax dollars yourself, you pay tax only on the employer's contributions and the investment growth, not on what you put in. Your Form 1099-R will show which portion is taxable.

What happens if I don't have taxes withheld from my pension?

You will owe the full tax bill when you file your return in April. If you owe more than $1,000, the IRS may charge you an underpayment penalty. Most people avoid this by asking their pension administrator to withhold taxes from each payment, spreading the cost throughout the year.

Can I move to a state with no income tax and avoid state tax on my pension?

Yes. If you move to Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, or New Hampshire before you start taking your pension, you will owe no state tax on it. The state where you live when you begin receiving payments is the one that taxes it going forward.

Is my military pension taxed differently than a civilian pension?

At the federal level, military pensions are taxed the same as civilian pensions. However, many states exempt military pensions from state income tax entirely, even if they tax other pensions. Check your state's rules to see if you may have access to for this exemption.

Can I reduce the taxes I owe on my pension?

You cannot avoid the tax, but you can manage it. Adjust your withholding to match your actual tax liability, consider the timing of other income, and if you have both a pension and Social Security, understand how they combine to affect your tax bill. A tax professional can help you plan to minimize what you owe.
