Is your reenlistment bonus worth it?
Estimate only, for planning. Uses the standard SRB formula and the 22% federal supplemental-wage withholding rate; your actual tax, state tax, and your branch's current multiplier and payment split may differ. Confirm with your career/retention counselor before signing.

The timing move that makes it tax-free
Here's what most reenlistment guidance buries: the combat-zone tax break on a bonus is decided by the month you sign — not when the money hits your account, and not when you finish the obligation. If you reenlist during a month you're physically in a designated combat zone, qualified hazardous duty area, or direct-support area, the whole bonus is exempt from federal income tax, including installments paid years later, back home.
The reverse is also true and catches people out: if you sign at home and an installment happens to land while you're later deployed, that installment is still taxed — because you signed in a non-qualifying month. The signing month is the only thing that counts.

Common questions
How is a reenlistment bonus (SRB) calculated?
SRB = your monthly basic pay × your award-level multiplier × the number of additional years you reenlist for. For example, $3,200 monthly basic pay × a 3.0 multiplier × 4 years = $38,400, subject to caps of $30,000 per year of obligated service and $180,000 per agreement.
Is a reenlistment bonus tax-free if I sign in a combat zone?
Yes. Under the Combat Zone Tax Exclusion, the entire bonus — including every future installment — is exempt from federal income tax if you reenlist or sign the agreement during a month you are physically serving in a designated combat zone, qualified hazardous duty area, or direct-support area. What matters is the month you sign, not when the money is paid. (DoD FMR Vol 7A, Ch 44, Table 44-4, Rule 5; 26 U.S.C. §112.)
How much of my bonus is withheld for taxes?
If the bonus is taxable, the military withholds federal income tax at the supplemental-wage flat rate, currently 22% (37% on amounts over $1,000,000). State income tax follows the same taxable/not-taxable determination and is based on your state of legal residence. A combat-zone-signed bonus has 0% federal withholding.
Are reenlistment bonuses paid all at once?
Commonly, 50% is paid up front and the remaining 50% in equal annual anniversary installments over your obligation, though the split varies by branch and fiscal year. Combat-zone tax-free treatment still applies to every installment as long as you signed in a qualifying month.
