Yes, a federal civil service retirement annuity is taxable. Most of each monthly payment counts as ordinary income on your federal return; the only tax-free slice is the part that represents your own after-tax contributions to the retirement fund, and that exclusion runs out once you’ve recovered what you paid in. States handle the same income very differently, from full exemption to full taxation.
What Part of Your Annuity Is Tax-Free
Whether you retired under the Civil Service Retirement System (CSRS) or the Federal Employees Retirement System (FERS), a portion of every paycheck you earned went to the retirement fund, and those contributions came out of already-taxed wages.1U.S. Office of Personnel Management. CSRS Information The IRS lets you pull that money back out without paying tax on it a second time. Everything else in your monthly annuity, meaning the government’s share plus accumulated interest, is taxable as ordinary income.2Internal Revenue Service. Publication 575 (2025), Pension and Annuity Income – Cost (Investment in the Contract)
Most federal retirees calculate the tax-free portion with the Simplified Method described in IRS Publication 721.3Internal Revenue Service. Publication 721 (2024), Tax Guide to U.S. Civil Service Retirement Benefits You divide your total after-tax contributions by a fixed number of expected monthly payments tied to your age when the annuity started. For a single-life annuity starting after November 18, 1996:4Internal Revenue Service. Publication 575 (2025), Pension and Annuity Income
- Age 55 or younger: 360 months
- Age 56 to 60: 310 months
- Age 61 to 65: 260 months
- Age 66 to 70: 210 months
- Age 71 or older: 160 months
An annuity that includes a survivor benefit for a spouse uses a different table based on your combined ages at the annuity starting date. To see how the math works: a retiree who starts collecting at age 60 with $31,000 in after-tax contributions divides $31,000 by 310, which gives a $100 tax-free amount each month. That $100 comes out of every payment until the full $31,000 has been recovered.3Internal Revenue Service. Publication 721 (2024), Tax Guide to U.S. Civil Service Retirement Benefits
After you’ve recovered your entire investment, every dollar of every future payment is fully taxable. Live past the divisor and there’s no exclusion left. Die before recovering the full amount, and the remaining balance can be claimed as an itemized deduction on your final tax return.3Internal Revenue Service. Publication 721 (2024), Tax Guide to U.S. Civil Service Retirement Benefits
Disability Retirement Is Taxed Differently Until You Hit MRA
If you retired on disability, the rules shift until you reach the FERS minimum retirement age, which runs from 55 to 57 depending on birth year.5U.S. Office of Personnel Management. What Is a Minimum Retirement Age (MRA) Plus 10 Annuity Under FERS Before that age, the IRS treats disability payments as wages, not pension income. You report them on the wages line, and you cannot use the Simplified Method to start recovering your after-tax contributions yet.6Internal Revenue Service. Publication 907 (2025), Tax Highlights for Persons With Disabilities – Disability Pensions Because those payments count as earned income during this window, they can qualify you for the earned income tax credit if you meet the other rules.7Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income – Disability Pensions
The day after you reach minimum retirement age, the payments are reclassified as a pension annuity. You start the Simplified Method then and report the income on the pension lines going forward.6Internal Revenue Service. Publication 907 (2025), Tax Highlights for Persons With Disabilities – Disability Pensions Miss that transition and you’ll keep being taxed as an employee, forfeiting years of cost recovery you’re entitled to.
How Survivor Annuities Are Taxed
A surviving spouse receiving a CSRS or FERS survivor annuity uses the Simplified Method the retiree was using, and the monthly tax-free amount carries over from the original calculation. If the retiree had already recovered the full cost before death, every dollar the survivor receives is taxable from the start.3Internal Revenue Service. Publication 721 (2024), Tax Guide to U.S. Civil Service Retirement Benefits
When children receive a temporary survivor annuity alongside a spouse, each child’s portion is that child’s own income, not the surviving parent’s, and the tax-free exclusion is split proportionally among the beneficiaries based on payment size.3Internal Revenue Service. Publication 721 (2024), Tax Guide to U.S. Civil Service Retirement Benefits Survivors of public safety officers killed in the line of duty can generally exclude the survivor annuity from income to the extent it relates to the officer’s service. Up to $5,000 in death benefit payments can be excluded from gross income for beneficiaries of a retiree who dies before reaching mandatory retirement age after a disability retirement.8eCFR. 26 CFR 1.101-2 – Employees’ Death Benefits
Your Pension Can Make Social Security Taxable Too
If you collect Social Security along with a FERS annuity, the pension itself can push a big share of your Social Security benefits into taxable territory. The IRS uses a combined income figure: half of your Social Security benefits plus all other income, including your civil service annuity. Cross the thresholds and part of your Social Security becomes taxable:9Internal Revenue Service. IRS Reminds Taxpayers Their Social Security Benefits May Be Taxable
- Single filers with combined income between $25,000 and $34,000: up to 50% of benefits may be taxable
- Single filers above $34,000: up to 85% of benefits may be taxable
- Joint filers between $32,000 and $44,000: up to 50% of benefits may be taxable
- Joint filers above $44,000: up to 85% of benefits may be taxable
These thresholds have never been indexed for inflation, so a civil service annuity by itself will push most retirees past the $25,000 or $32,000 floors. In practice, most federal retirees who receive both a pension and Social Security end up paying tax on 85% of their Social Security benefits. CSRS retirees who earned little or no Social Security on their own may sidestep this, though a spouse’s benefits could still be affected on a joint return.
State Tax on Federal Civil Service Retirement
State treatment varies widely and often drives where federal retirees settle. Nine states impose no individual income tax at all, so retirees there only deal with the IRS. Several more states fully exempt government pension income no matter the amount.
Many states sit in between with a partial exclusion. These exclusions typically range from a few thousand dollars up to $65,000 or more, and they frequently come with conditions like a minimum age or a household income cap. Some states that do tax federal pensions use the federal taxable amount as the starting point and then apply their own rates. A handful use targeted credits for low-income seniors rather than broad exemptions.
State tax laws move during annual legislative sessions, so verify your state’s current rules each year before filing, especially if you’re weighing a move.
The 1099-R, Withholding, and Underpayment Penalties
The Office of Personnel Management mails Form CSA 1099-R by January 31 each year, or posts it online, showing the total gross annuity, the taxable amount, and the federal tax withheld.10U.S. Office of Personnel Management. Tax Information for Annuitants Survivors receive Form CSF 1099-R. If yours hasn’t arrived by mid-February, you can pull it through OPM’s online portal.11U.S. Office of Personnel Management. Get Your 1099-R Tax Form
Federal law treats annuity payments like wages for withholding purposes: unless you elect otherwise, tax is withheld from each payment as if it were a paycheck.12Office of the Law Revision Counsel. 26 USC 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income You can adjust or stop federal and state withholding at any time through OPM Retirement Services Online under Federal Tax Withholdings or State Tax Withholdings, and the change typically takes effect the next payment cycle.13U.S. Office of Personnel Management. Change Your Federal and State Income Tax Withholdings
Getting withholding right matters because the IRS charges an underpayment penalty when you owe $1,000 or more at filing time and haven’t met a safe harbor. You can avoid it by paying at least 90% of your current year’s tax or 100% of last year’s tax, whichever is less. If your adjusted gross income exceeded $150,000 in the prior year, or $75,000 if married filing separately, the prior-year safe harbor rises to 110%.14Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty Retirees with TSP withdrawals, investment income, or other income beyond the annuity should review withholding every year; leaning on the default annuity withholding alone often leaves a gap.
