A bonus is not subject to Social Security or Medicare: for service members those taxes apply to basic pay only (26 U.S.C. 3121(i)(2)). Federal tax is withheld at 22% of each payment; what you finally owe depends on your bracket, so you may get some back or owe more when you file. The state figure estimates the extra tax the bonus adds to a full year of basic pay at your grade; DFAS withholds at the state rate when it pays. In a combat zone month, enlisted members and warrant officers exclude the whole bonus, installments included; officers exclude up to $11,391.90 for that month.

Under the Blended Retirement System, the mid-career bonus for staying past 12 years (8 in the Coast Guard) is continuation pay: continuation pay calculator

How It Works

Enlistment and reenlistment bonuses can run into the tens of thousands of dollars, but the figure on your contract is not the figure that lands in your account. Enter the bonus amount, or let the calculator work out a Navy, Air Force or Space Force Selective Reenlistment Bonus from your multiple, and it shows what is withheld at payout, what you finally owe at your tax bracket, and your state's share under its own rules for military pay.

Three things set the tax. There is no Social Security or Medicare on a bonus: for service members those taxes apply to basic pay only (26 U.S.C. 3121(i)(2)), so a bonus is not FICA wages. Federal income tax is withheld at the flat 22% supplemental rate (37% only on supplemental pay above $1 million in a year), and the tax you finally owe is set by your bracket, which the second result uses. State tax depends on your state of legal residence, not where you are stationed: 9 states have no tax on wages, 14 exempt active-duty pay entirely, 7 exempt it only while you are stationed outside the state, and the rest tax it; Georgia, for example, taxes a resident's active-duty pay and bonuses at 4.99% in 2026. A bonus earned in a month you serve in a combat zone is excluded from federal income tax, installments included, and no state checked taxes it either; commissioned officers can exclude up to $11,391.90 for that month.

A Selective Reenlistment Bonus in the Navy, Air Force and Space Force is your monthly basic pay on the day before you reenlist × the months of added service ÷ 12 × the multiple on the current SRB list, capped at $30,000 per year of added service, $180,000 per bonus and the award ceiling for your rating. It is usually paid half at reenlistment and the rest in equal payments on each anniversary, each taxed when it is paid. The Army (MILPER 26-241) and Marine Corps (MARADMIN 023/26) pay flat dollar amounts instead, so enter those directly, and the Coast Guard authorized no SRB for fiscal 2026. The state figure is an estimate of the extra tax the bonus adds to a full year of basic pay at your grade; DFAS withholds state tax at the state's rate when it pays.

Example: $20,000 Enlistment Bonus for a Georgia Recruit

  1. 1 Input: bonus amount $20,000, pay grade E-1, Georgia, single, not in a combat zone, 12% bracket.
  2. 2 Withholding at payout: federal 22% of $20,000 = $4,400. Social Security and Medicare: $0, because a bonus is not basic pay. The calculator used to take another $1,530 for FICA here.
  3. 3 Georgia taxes a resident's active-duty pay and bonuses wherever the member is stationed, at a flat 4.99% in 2026, so the bonus adds $998 of Georgia tax. Take-home after withholding: $20,000 − $4,400 − $998 = $14,602.
  4. 4 At a 12% federal bracket the tax finally owed on the bonus is $2,400, not the $4,400 withheld, so the actual net is $16,602 and the difference comes back as a refund. A Navy E-5 over 4 years reenlisting for 48 months at a multiple of 2 would instead get $3,946.80 × 48 ÷ 12 × 2 = $31,574.40, paid as $15,787.20 up front and three anniversary payments of $5,262.40.

Frequently Asked Questions

How much tax is taken from a military bonus?
Federal income tax is withheld at a flat 22%, plus state tax if your state of legal residence taxes military pay. No Social Security or Medicare is taken, because for service members those taxes apply to basic pay only (26 U.S.C. 3121(i)(2)). A $20,000 bonus has $4,400 of federal tax withheld, leaving $15,600 before state tax; a Georgia resident also pays 4.99%, or $998.
Can I receive my military bonus tax-free?
Yes, if you reenlist or extend in a month in which you serve in a combat zone: IRS Publication 3 lets enlisted members and warrant officers exclude that reenlistment bonus from federal income tax, while commissioned officers are held to the monthly cap on combat zone pay. The test is the month of the reenlistment or extension. On a large bonus the saving runs to thousands of dollars.
How is a Selective Reenlistment Bonus (SRB) calculated?
In the Navy, Air Force and Space Force the SRB is your monthly basic pay × months of added service ÷ 12 × the multiple on the current SRB list, capped at $30,000 per added year and $180,000 per bonus. An E-5 over 4 years reenlisting for 48 months at a multiple of 2 gets $3,946.80 × 4 × 2 = $31,574.40, half at reenlistment and the rest in anniversary payments. The Army and Marine Corps pay flat amounts set in their MILPER and MARADMIN messages.
When are military bonuses paid out?
By law a bonus may be paid in a lump sum or in periodic installments, as the service decides (37 U.S.C. §331(c)(2)), and the method is written into the agreement you sign. Check that agreement for the schedule.
