Most pensions are taxable income, but the amount you pay depends on how you funded the plan and when you withdraw
Whether you owe tax on your pension comes down to one question: did you or your employer pay the contributions with pre-tax dollars? If yes, the withdrawals are taxable. If you paid with after-tax dollars, only the earnings are taxed. Most traditional pensions fall into the first category, meaning you'll report the full amount as income when you receive it.
The tax you owe is calculated at your ordinary income tax rate — the same rate as wages or salary. A pension payment of $2,000 per month is treated like $2,000 in monthly income. Your employer or pension plan administrator will withhold federal tax automatically unless you tell them not to, but you're still responsible for any balance owed when you file your return.
State and local taxes may also apply, depending on where you live and where the pension is paid from. Some states don't tax pensions at all; others tax only military pensions or only pensions from government employers. A few tax all pensions the same way they tax wages.
Key Takeaways
- Traditional pensions funded with pre-tax contributions are fully taxable as ordinary income at your marginal tax rate.
- Your pension plan will withhold federal tax automatically, but you may owe more or less when you file your return depending on your total income and deductions.
- State and local tax treatment varies widely — some states exempt pensions entirely, while others tax them like wages.
- If you made after-tax contributions to your pension, only the earnings portion is taxed; your contributions come out tax-free.
- You must report your pension on your federal tax return even if no tax is withheld, and failure to do so can result in penalties.
How withholding works and why it matters
When your pension starts, your plan administrator will ask you to complete a W-4P form (Withholding Certificate for Pension or Annuity Payments). This form tells them how much federal tax to hold from each payment. Most people claim a number of allowances based on their filing status and other income sources.
The withholding is an estimate. If you have other income — Social Security, investment earnings, a part-time job — your total tax bill may be higher than what's withheld from the pension alone. If you have very little other income, you might have too much withheld and receive a refund when you file. You can adjust your W-4P at any time by contacting your plan administrator.
If you don't want any tax withheld, you can request that on the W-4P, but you're still responsible for paying the tax owed. The IRS can impose penalties and interest if you underpay throughout the year. Most people find it simpler to let withholding happen and adjust it if needed.
The difference between pre-tax and after-tax contributions
A traditional pension is usually funded entirely by your employer using pre-tax dollars. You never paid into it directly, so the full amount you receive is taxable. This is the most common type of pension for government workers, teachers, and some private-sector employees.
Some pensions allow or require you to make after-tax contributions — money you put in from your own paycheck after taxes were already taken out. If you did this, you have a cost basis in the plan. When you withdraw, your contributions come out tax-free, but the earnings and employer contributions are taxed. Your pension plan should provide a statement showing how much of your balance is after-tax contributions; use that to calculate your taxable portion.
If you're unsure whether your contributions were pre-tax or after-tax, ask your plan administrator for a cost basis statement or basis calculation. This document breaks down exactly how much of your pension is taxable. You'll need it to file your return correctly.
State and local tax treatment by category
Tax treatment of pensions varies significantly by state. Understanding your state's rules can affect how much you actually take home.
| Tax Status | States | What It Means |
|---|---|---|
| No state income tax | Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming | Pensions are not taxed at the state level, regardless of source. |
| All pensions exempt | Illinois, Mississippi, Pennsylvania | State does not tax any pension income, including private pensions. |
| Government pensions exempt; private taxed | California, Colorado, Georgia, Louisiana, Massachusetts, Michigan, Missouri, New Mexico, North Carolina, Ohio, Oklahoma, Oregon, Virginia, West Virginia | Pensions from government employers (federal, state, local) are exempt; private pensions are taxed. |
| Military pensions exempt; others taxed | Connecticut, Indiana, Iowa, Kansas, Kentucky, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, New York, North Dakota, Rhode Island, South Carolina, Utah, Vermont, Wisconsin | Only military pensions are exempt; civilian government and private pensions are taxed. |
| All pensions taxed | Arkansas, Delaware, Hawaii, Idaho, Maine, New Mexico (some), Ohio (some), Rhode Island (some), Vermont (some) | Pensions are taxed like ordinary income, with possible age-based deductions. |
Some states offer an age-based deduction or exemption — for example, a state might exempt the first $10,000 of pension income if you're over 65, or exempt pensions only if your total income is below a certain threshold. Contact your state tax authority or check your state's tax website to confirm the exact rules for your situation.
How to report pension income on your federal tax return
Pension income is reported on Form 1040 (the main federal income tax return) on the line for pensions and annuities. Your pension plan will send you a Form 1099-R by January 31 showing the total amount paid to you in the previous year and the amount of federal tax withheld. Use this form to complete your return.
If part of your pension is after-tax contributions (your cost basis), you'll need to calculate the taxable portion. The IRS provides a worksheet in the Form 1040 instructions, or you can use the Simplified Method if you're receiving a pension from a may have access to plan. Your plan administrator or a tax professional can help you determine this if it's unclear.
You must report your pension even if no tax was withheld or if the amount withheld was zero. Failure to report it can trigger an IRS notice and penalties. If you receive multiple pensions, report each one separately on your return.
What happens if you take a lump-sum distribution instead of monthly payments
Some pension plans allow you to take your entire balance as a single payment instead of receiving it monthly. This lump sum is fully taxable in the year you receive it, which can push you into a higher tax bracket and increase your overall tax bill significantly.
If you roll the lump sum into an Individual Retirement Account (IRA) or another may have access to retirement plan within 60 days, you can defer the tax. This is called a rollover. If you don't roll it over, the full amount is taxable immediately, and your plan will withhold 20 percent automatically. You may owe additional tax when you file your return.
Before taking a lump sum, calculate the tax impact. A financial advisor or tax professional can show you the difference between taking the lump sum, rolling it over, and taking monthly payments. The choice affects not only your immediate tax bill but also your future tax situation and Social Security taxation.
Special rules for federal employee pensions and military pensions
Federal employee pensions (from FERS or CSRS) are taxed like any other pension — the full amount is taxable as ordinary income. However, federal employees who contributed to the Thrift Savings Plan (TSP) may have both pre-tax and after-tax portions, depending on how they funded their account.
Military pensions are fully taxable at the federal level, even though many states exempt them. If you're a military retiree, you'll owe federal tax on the full amount, but your state may not tax it. Some military retirees also receive Survivor Benefit Plan (SBP) payments, which are also taxable.
Railroad Retirement benefits are taxed differently than Social Security or pensions and follow their own rules. If you receive railroad retirement income, consult the Railroad Retirement Board or a tax professional for guidance on your specific situation.
Frequently Asked Questions
Do I have to pay tax on my pension if I'm over 65?
Age alone does not exempt you from pension tax. However, if you're over 65, you may be able to claim an additional standard deduction on your federal return, which reduces your taxable income. Some states also offer age-based pension exemptions. Check your state's rules and consult a tax professional to see if you may have access to.
What if I didn't have enough tax withheld from my pension?
You'll owe the difference when you file your return. To avoid this in the future, adjust your W-4P to increase withholding, or make quarterly estimated tax payments. The IRS charges interest and penalties on underpayment, so it's better to withhold too much than too little.
Can I deduct my pension contributions from my taxes?
If your contributions were pre-tax (taken from your paycheck before taxes), they were already deducted when you earned them. If they were after-tax, you cannot deduct them again. Your cost basis in the plan reduces your taxable income when you withdraw, but it's not a separate deduction.
Is my pension taxed if I'm still working?
Yes. Pension income is taxed regardless of whether you're employed. However, if you're still working and earning wages, your total income may push you into a higher tax bracket, increasing the tax on both your wages and your pension. Some states have special rules if you're receiving a pension and still working for the same employer.
What if I move to a different state after I start receiving my pension?
You'll owe tax to your new state on your pension income, unless your new state exempts pensions. Your old state generally won't tax you once you've moved. File a return in your new state and update your W-4P if necessary. Some states have reciprocal agreements, so check both states' rules.
