Are Government Pensions Taxable? CSRS, FERS, and Military Rules

Government pensions are taxable on your federal return in most cases, but usually not in full: the portion of each payment that represents contributions you already paid tax on during your career comes back to you tax-free, and the rest is taxed as ordinary income. Whether government pensions are taxable at the state level is a separate question with a different answer in almost every state, ranging from full exemption to treatment that mirrors federal rules. Disability-related military and public safety benefits get their own carve-outs, and some are fully exempt.

Why Most of a CSRS or FERS Annuity Is Taxable

A widespread misconception is that CSRS and FERS contributions went in pre-tax. They did not. Both systems take contributions out of your paycheck after federal income tax has already been withheld, so you paid tax on that money when you earned it.¹ CSRS employees contribute 7 to 8 percent of pay; FERS rates run from 0.8 percent to 4.4 percent depending on hire date.²

Those after-tax contributions are your cost basis in the annuity. The government’s matching contributions and every dollar of investment earnings were never taxed. Because the untaxed portion is much larger than the after-tax portion, the majority of each monthly annuity payment is taxable as ordinary income, and only a small slice returns tax-free.

Recovering Your Cost Basis

If your annuity started after November 18, 1996, the IRS Simplified Method sets how much of each payment is tax-free.¹ You divide your total after-tax contributions by a number of months the IRS assigns based on your age at retirement (or the combined ages if the annuity includes a survivor benefit). The quotient is the fixed dollar amount you exclude from income each month.

That exclusion does not change when your annuity gets a cost-of-living increase. Once you have recovered the full cost basis, every dollar of every future payment is taxable. OPM generally runs the calculation and prints the taxable amount on your 1099-R, but checking the math against the worksheet in Publication 721 is worth the time.

If you or a survivor annuitant die before the cost basis is fully recovered, the unrecovered amount can be claimed as an itemized deduction on the final tax return.¹ Surviving spouses often miss this.

Thrift Savings Plan Withdrawals

The TSP follows the same rules as a private 401(k). Traditional TSP contributions went in before tax, so every dollar of a traditional withdrawal, including earnings, is taxed as ordinary income.³

Roth TSP contributions were made with after-tax money, so your contributions always come out tax-free. The earnings are also tax-free if the withdrawal is qualified: at least five years have passed since January 1 of the year of your first Roth contribution, and you are 59½, permanently disabled, or deceased.³ Pull earnings before meeting both tests and the earnings portion may be taxable.

Military Retired Pay and the Disability Exceptions

Standard military retired pay based on years of service is fully taxable as ordinary income. The favorable treatment lives in the disability rules, and the distinctions among them decide the tax bill.

VA Disability Compensation

Compensation paid directly by the Department of Veterans Affairs is completely exempt from federal income tax.⁴ The exemption covers monthly disability payments, dependency and indemnity compensation for survivors, and other VA-administered benefits, at any amount.

Military Disability Retired Pay

If you retired from the military because of a disability rather than years of service, the portion of your retired pay attributable to the disability is excluded from gross income.⁵ Where retirement pay is instead computed on years of service, the amount exceeding what a pure disability calculation would produce can remain taxable.⁶

CRSC vs. CRDP

Retirees with both a VA disability rating and military retired pay usually receive one of two concurrent-payment programs. Combat-Related Special Compensation is tax-free. Concurrent Retirement and Disability Pay is taxable in the same manner as regular retired pay.⁷ Both restore retired pay that was previously offset by VA compensation, but only CRSC keeps the tax-free character of that offset.

Survivor Benefit Plan

Payments from the military Survivor Benefit Plan are fully taxable to the surviving spouse or beneficiary as ordinary income.⁸

Civilian Government Disability Retirement

Retire on disability from a government job before you reach the plan’s minimum retirement age and the payments are treated as wages, reported on the wages line of your return.⁹ Minimum retirement age here means the earliest age you could have taken a regular, non-disability pension. Once you cross that age, the payments become pension income, move to the pension lines of the return, and you can start using the Simplified Method to recover any after-tax basis.

A separate rule reaches further: disability payments that qualify as workers’ compensation for a job-related injury or occupational illness are fully excluded from gross income with no age threshold.⁵

Early Withdrawal Penalty Exceptions for Government Workers

Taxable distributions from a qualified retirement plan taken before age 59½ normally carry a 10% additional tax on top of ordinary income tax.¹⁰ Government employees have several exits from that penalty.

Separate from your government job during or after the year you turn 55 and distributions from that employer’s plan are exempt from the 10% penalty. Defined benefit and defined contribution plans both qualify.
Public safety employees (police, firefighters, EMS, corrections, federal law enforcement, customs and border protection, air traffic controllers, federal firefighters) can take penalty-free distributions after separating from service at age 50, or after 25 years of service, whichever comes first.¹⁰
Governmental 457(b) plans are not subject to the 10% early withdrawal penalty at any age. The one exception is money rolled into the 457(b) from a different type of plan or IRA.¹¹

One trap deserves emphasis. The public safety exception attaches to distributions from the employer’s plan. Roll the balance into an IRA and then withdraw, and the exception is gone and the 10% penalty applies. Public safety retirees planning to live on their retirement funds before 59½ often lose real money by rolling too soon.

The $3,000 Health Insurance Exclusion for Retired Public Safety Officers

Retired public safety officers who separated because of disability or after reaching normal retirement age can exclude up to $3,000 per year from gross income when their pension plan pays health or long-term care insurance premiums directly to the insurer.¹² Two retired public safety officers filing jointly can each claim it, up to $6,000 combined.

The distribution has to come from an eligible governmental retirement plan and go directly toward qualified premiums. You elect the exclusion on your tax return. It applies only to amounts that would otherwise be taxable, so it does not eat into your tax-free cost basis recovery. Many eligible retirees leave this on the table because they don’t know it exists.

State Taxation of Government Pensions

State income tax rules for government pensions have no connection to federal rules, and the variation is enormous. Nine states impose no state income tax at all, so a government pension paid to a resident there is not taxed at the state level. Among states with an income tax, some exempt all pension income (including federal, military, and state pensions), some exempt only their own state employees while taxing federal retirees, some exempt military retired pay while taxing civilian government pensions, some offer a fixed pension deduction that phases out with income or age, and some track federal rules and tax most government pensions as ordinary income while allowing only Simplified Method basis recovery. The dollar limits, age triggers, and income cutoffs are specific to each state, so the treatment for your pension needs to be checked in the state where you actually live.

What Happens When You Move

Federal law bars any state from taxing retirement income paid to someone who is not a resident or domiciliary of that state.¹³ The protection covers governmental plans, 401(a) qualified trusts, 457 deferred compensation plans, IRAs, 403(b) plans, and military retired pay. Move from a high-tax state to a no-tax state after you retire and your former state cannot follow you.

The trick is proving the move. Domicile is your permanent legal home, and it takes both physical relocation and intent to stay. States look at voter registration, driver’s license, vehicle registration, where you file state returns, and where you spend most of your time. Renting a place in a no-tax state while keeping the house, the accounts, and the ties back home is not enough. A messy move can leave two states each claiming your pension income.

Withholding, 1099-R, and Where It Goes on Your Return

Pension payments are subject to federal withholding by default, calculated as if the payment were wages.¹⁴ You control the amount by filing Form W-4P with your pension administrator, including line 4(c) for extra withholding, or an election of no withholding at all.¹⁵

Retirees drawing from several sources (a FERS annuity, TSP, Social Security, investments) commonly underwithhold, because each payer only sees its own slice. The IRS charges an underpayment penalty unless you owe less than $1,000 after credits and withholding, pay at least 90% of your current-year tax, or pay at least 100% of last year’s tax (110% if your AGI was over $150,000).¹⁶ Requesting extra withholding on W-4P is usually simpler than making quarterly estimated payments.

Every January the paying agency issues Form 1099-R.¹⁷ OPM issues it for CSRS and FERS annuities; the TSP issues its own for any withdrawals. Box 1 is the gross distribution, Box 2a is the taxable amount, and Box 4 is federal tax already withheld. On Form 1040, Box 1 goes on Line 5a and Box 2a on Line 5b. If Box 2b is marked “Taxable amount not determined,” you run the Simplified Method yourself using the worksheet in the Form 1040 instructions and put the result on Line 5b.
