Are FERS Annuities and Pensions Taxable? Understanding Taxes On FERS Annuity
Understanding how your federal retirement income is taxed?, taxes on fers annuity, is fers pension taxable?, is fers annuity taxable? is essential for effective financial planning. Your FERS annuity, Social Security benefits, and TSP withdrawals are all subject to federal income tax, with each taxed as ordinary income based on your tax bracket. Below, we break down how each income source is taxed and what you need to know about withholding. Now lets break down the taxes on fers annuity.
FERS Annuity Taxation
Lets find out the answer that is fers annuity taxable? The majority of your FERS annuity is taxable at the federal level. While you won’t be taxed on the portion of your annuity that comes from your previously taxed contributions, those contributions are spread out over your expected lifetime. As a result, most of your annuity payments will be subject to taxation. Each year, you’ll receive a 1099-R form from the Office of Personnel Management (OPM), which will indicate the taxable portion of your annuity.
Social Security Taxation
Up to 85% of your Social Security benefits may be subject to federal income tax, depending on your total income. The higher your income, the greater the percentage of your benefits that will be taxed. The exact taxable amount is determined when you file your federal tax return.

TSP Withdrawals: Traditional vs. Roth
Traditional TSP withdrawals are fully taxable as ordinary income.
Roth TSP withdrawals are tax-free if they meet the qualified withdrawal requirements: you must have held the account for at least five years and be at least 59½ years old. If these conditions aren’t met, any earnings withdrawn will be subject to taxes, though your original contributions remain tax-free. Unlike a Roth IRA, Roth TSP withdrawals are taken proportionally from contributions and earnings.

Tax Withholding on Your Retirement Income
Taxes aren’t always automatically withheld from your retirement income, so you may need to take action to avoid unexpected tax bills or penalties.
FERS Annuity Withholding
When you retired, you likely filled out a W-4P form, which determined the amount of tax withheld from your FERS annuity. If you based it on your last W-4 as an employee, it should generally cover your tax liability.
Social Security Withholding
Unlike your FERS annuity, Social Security does not automatically withhold taxes unless you request it. You can do this by:
- Completing a W-4V form to have taxes withheld directly from your Social Security payments.
- Making quarterly estimated tax payments (due in April, June, September, and January). If you prefer a set-it-and-forget-it approach, opting for automatic withholding can help ensure you don’t fall behind on tax payments.

TSP Withholding
Tax withholding for TSP withdrawals varies by payment type. For example:
Installment payments expected to last 10 years or more are withheld as if you were married, filing jointly, with three exemptions—which may not be enough to cover your tax liability.
Most other withdrawals are subject to a 20% federal tax withholding, which may or may not be sufficient, depending on your total income and tax situation.
State Taxes on Retirement Income
If you live in a state that taxes retirement income or Social Security benefits, be aware that neither the TSP nor Social Security will withhold state taxes. You may need to make estimated payments or adjust withholding from other sources of income. Want to know about the federal government retirement formula?.
Plan Ahead to Avoid Tax Surprises
If you’re newly retired or planning to retire soon, ensure you have enough tax withheld from your income sources to cover your obligations and avoid penalties. Tax planning is about minimising your tax burden legally—just make sure you don’t unintentionally underpay, as that can lead to penalties.
By staying informed about how your retirement income is taxed and planning accordingly, you can better manage your finances and avoid unexpected tax liabilities.
