Most pension income is taxable, but the amount you owe depends on whether your pension comes from a traditional plan, a Roth account, or military or government service

You will owe federal income tax on most pension payments. The IRS treats pension income as ordinary income, which means it is taxed at your regular tax rate — the same rate applied to wages or salary. However, some pensions are partially or fully tax-free depending on where the money came from and how it was funded.

The key distinction is whether your employer or you paid the contributions. If your employer paid the full cost of your pension with pre-tax dollars, you pay tax on the entire payment. If you contributed your own after-tax money, you pay tax only on the earnings portion, not on the return of your own contributions. Military pensions and some government pensions follow different rules entirely.

State income tax on pensions also varies widely. Some states tax all pension income, some tax only certain types, and a few exempt pensions entirely. You need to know both the federal picture and your state's rules to calculate what you actually owe.

Key Takeaways

  • Traditional pension payments are taxed as ordinary income at your federal tax rate, and you report them on Form 1040 and Schedule 1.
  • If you contributed after-tax money to your pension, you use Form 8606 to calculate the non-taxable portion of each payment.
  • Military pensions and some federal employee pensions have their own tax treatment and may be partially or fully excluded from taxable income.
  • State income tax on pensions ranges from zero to full taxation, and some states offer pension exemptions for residents over a certain age.
  • Pension income counts toward your total income for purposes of Social Security taxation and Medicare premium calculations.

How traditional pension payments are taxed

A traditional pension — the kind paid by an employer based on years of service — is funded with pre-tax contributions. Your employer deducted the money from company profits before paying corporate taxes, and you never paid income tax on those contributions when they were made. Because of that, the entire pension payment you receive is taxable income.

You report this income on your federal tax return using Form 1040 and Schedule 1 (Additional Income and Adjustments). The pension issuer — your former employer's pension plan administrator — sends you a Form 1099-R each January showing the gross amount paid in the prior year. You enter that amount on your return, and it is taxed at your ordinary income tax rate for the year.

The tax is not withheld automatically unless you request it. Many retirees ask their pension plan to withhold federal income tax from each payment, similar to how an employer withholds from a paycheck. If you do not request withholding and owe tax, you may need to make quarterly estimated tax payments to avoid penalties. Your pension administrator can tell you how to set up withholding or can provide a Form W-4P to adjust the amount.

When you contributed after-tax money to your pension

If you paid part of your pension contributions with money that was not deducted from your taxable income — after-tax contributions — you do not pay tax again on that portion when you receive it. The IRS calls this your cost basis. You pay tax only on the earnings that accumulated on top of your contributions.

To calculate the non-taxable portion, you use Form 8606 (Nondeductible IRAs). Despite its name, this form also applies to pensions funded partly with after-tax money. You need to know three numbers: the total after-tax contributions you made over your entire career, the total value of the pension at the time you started receiving payments, and the total amount you received during the year.

The calculation is straightforward but requires documentation. Divide your total after-tax contributions by the total pension value to get a percentage. Multiply that percentage by the amount you received that year — that portion is tax-free. The remainder is taxable. You will need records from your employer or pension plan showing your contribution history. If those records are missing, the IRS has procedures for reconstructing them, but it is easier to request them from your plan administrator before you retire.

Military and federal employee pensions

Military pensions have special tax treatment. If you are a military retiree who served before January 1, 2006, your pension may be partially excluded from taxable income under the Uniformed Services Former Spouses' Protection Act, though this applies mainly in divorce situations. Most military retirees pay tax on the full amount, but some may be may be able to access for state-level exemptions.

Federal employee pensions — including those from the Civil Service Retirement System (CSRS) and the Federal Employees' Retirement System (FERS) — are taxed as ordinary income at the federal level. However, many states exempt federal pensions from state income tax, even if they tax other pensions. If you are a federal retiree living in a state that taxes pensions, check whether your state offers a federal pension exemption.

Railroad retirement benefits are handled differently still. The Railroad Retirement Board issues Form RRB-1099, not Form 1099-R, and the taxation rules differ from standard pensions. If you receive railroad retirement income, refer to the Railroad Retirement Board's tax guidance or speak with a tax preparer familiar with railroad benefits.

State income tax on pensions

State taxation of pensions varies dramatically. Some states tax all pension income the same way the federal government does. Others tax only certain types — for example, taxing private pensions but not government pensions. A few states exempt all pension income from state tax.

States that currently exempt all pension income from state income tax include Florida, Illinois, Mississippi, Pennsylvania, and Tennessee, though rules change and some exemptions explore only to residents over a certain age. States like New York and California tax all pensions as ordinary income. Most states fall somewhere in between, with exemptions for government pensions, military pensions, or pensions for residents over 59½ or 62.

If you are retired and considering moving, state pension tax treatment can significantly affect your take-home income. Research your current state's rules and any state you are considering. Your state's department of revenue website lists pension exemptions and the income thresholds that explore. If you move during the year, you may owe tax to both your old state and your new state for the portion of the year you lived in each.

How pension income affects Social Security and Medicare costs

Pension income counts toward your total income for two important calculations: whether your Social Security benefits are taxable, and how much you pay for Medicare premiums.

If your combined income — adjusted gross income plus non-taxable interest plus half your Social Security benefits — exceeds certain thresholds, part of your Social Security becomes taxable. The thresholds are $25,000 for single filers and $32,000 for married filing jointly. Pension income is included in this calculation, so a substantial pension can push you into a bracket where you owe tax on your Social Security.

Medicare premiums are also tied to income. If your modified adjusted gross income exceeds $97,000 (single) or $194,000 (married filing jointly) in 2024, you pay a higher premium for Medicare Part B and Part D. Pension income is included in this calculation. These thresholds are adjusted annually for inflation, so check the current year's limits on Medicare.gov.

Reporting pension income on your tax return

You report pension income on Form 1040, the main federal income tax return. The pension issuer sends you Form 1099-R by January 31 each year, showing the gross amount paid and any federal tax withheld. You enter the gross amount on Schedule 1 (Additional Income and Adjustments), line 5a for pensions and annuities.

If you have after-tax contributions, you also file Form 8606 to calculate and report the non-taxable portion. The non-taxable amount is subtracted from the gross, and only the taxable portion is included in your income.

If you received a lump-sum distribution from a pension plan — a single payment of your entire balance rather than monthly payments — the rules are more complex. Lump-sum distributions may be may be able to access for special tax treatment called net unrealized appreciation or forward averaging, which can reduce your tax. This requires Form 4972 and careful calculation. If you received a lump sum, consult a tax preparer or the IRS publication on lump-sum distributions before filing.

Frequently Asked Questions

Do I have to pay tax on my pension if I do not work anymore?

Yes. Pension income is taxable regardless of whether you are working. The tax is based on the income itself, not on your employment status. However, if your only income is a pension and it is below the standard deduction for your age and filing status, you may not owe federal tax. For 2024, the standard deduction is higher for people 65 and older, so check whether your pension income exceeds that threshold.

Can I avoid taxes on my pension by rolling it into an IRA?

Rolling a pension into an IRA does not avoid taxes — it defers them. When you withdraw money from a traditional IRA, you pay tax just as you would on a pension. A Roth conversion IRA is different: you pay tax upfront on the conversion, but future withdrawals are tax-free. This is a major financial decision with long-term consequences, so discuss it with a tax preparer or financial advisor before doing it.

What if my pension plan did not send me a Form 1099-R?

Contact your pension plan administrator when ready. You are required to report the income whether or not you receive the form, and the IRS has a record of it. If the form does not arrive by February 15, request a copy in writing and keep that request. If the plan cannot locate it, ask for a written statement of the amount paid, which you can use to file your return and request a corrected form later.

Are pension payments reduced by taxes before I receive them?

Only if you request withholding. By default, most pension plans pay the full gross amount and you are responsible for paying tax when you file your return or through quarterly estimated payments. You can ask your plan to withhold federal income tax from each payment using Form W-4P, which works like the withholding on a paycheck. Some plans also offer state tax withholding.

Does my pension count as earned income for tax purposes?

No. Pension income is not earned income — it is unearned income. This matters because you cannot claim the Earned Income Tax Credit, and you cannot contribute to a Roth IRA based on pension income alone. However, if you have other earned income from work, you can contribute to a Roth based on that earned income, even if you also receive a pension.
