The special pays, allowances, and tax breaks that stack on top of your base pay during a deployment.

What is deployment pay?

Deployment pay is not a single bonus line on your Leave and Earnings Statement. It is your normal base pay plus a stack of special pays, allowances, and tax breaks that switch on when you deploy. The exact stack depends on where you go and your family situation, but a combat-zone deployment typically adds Hostile Fire / Imminent Danger Pay, Family Separation Allowance, Hardship Duty Pay, the Combat Zone Tax Exclusion, and access to the Savings Deposit Program. Together these can raise take-home pay by hundreds — sometimes more than a thousand dollars — every month.

Deployment entitlements at a glance

The special pays explained

Imminent Danger Pay / Hostile Fire Pay

IDP and HFP pay a flat $225 per month for serving in an area the Department of Defense has designated as dangerous. It is prorated daily in some cases, but for most deployments you receive the full $225 for any month in which you serve at least one day in the zone.

Hardship Duty Pay

HDP-Location adds $50 to $150 per month for assignments to designated hardship locations where living conditions are substantially below those in the continental United States. The amount depends on the specific location's designation.

Family Separation Allowance

FSA pays $250 per month once you have been involuntarily separated from your dependents for more than 30 continuous days. It is designed to offset the extra cost of maintaining a household when you are away — childcare, second-vehicle upkeep, and similar expenses.

The Combat Zone Tax Exclusion: enlisted vs. officers

The Combat Zone Tax Exclusion (CZTE) is one of the biggest financial swings of a deployment, and it works differently by rank — a detail many guides skip.

• Enlisted members and warrant officers: ALL base pay earned in a designated combat zone is excluded from federal income tax for any month you served there, with no dollar cap. Re-enlistment bonuses signed in the zone can also be tax-free.
• Commissioned officers: the exclusion is capped at the highest enlisted pay rate plus the $225 imminent danger pay. Pay above that ceiling is still taxed. In practice this means senior officers shield a large but limited amount, while junior officers and all enlisted shield their entire base pay.

The exclusion is automatic — DFAS stops withholding federal income tax on qualifying pay, and the excluded amount does not appear as taxable wages on your W-2. State tax treatment varies, so check your state of legal residence.

The Savings Deposit Program: a guaranteed 10% return

The single most underused deployment benefit is the Savings Deposit Program (SDP). If you are deployed to a designated combat zone for 30 or more consecutive days, you can deposit up to $10,000 into an SDP account and earn a guaranteed 10% annual interest rate, compounded monthly. There is almost nowhere else on earth to get a risk-free, federally backed 10% return.

Key mechanics worth knowing:

• The 10% rate accrues only up to the $10,000 cap. Deposits are typically made by allotment, cash, or check through your finance office.
• Interest keeps accruing at 10% for up to 90 days after you leave the combat zone, then the account stops earning and should be withdrawn.
• The interest is taxable income (unlike your tax-excluded combat-zone base pay), but a guaranteed 10% return more than justifies the small tax bill. Max it out early in the deployment so your money compounds for the full tour.

Full enrollment details are published by DFAS at the official SDP page.

A worked example: how a deployment boosts take-home pay

Consider a hypothetical E-5 with around $3,300/month in base pay deploying to a combat zone with a spouse and child back home:

• Combat Zone Tax Exclusion: roughly $400-$500/month in federal tax that is no longer withheld (the entire base pay is tax-free).
• Imminent Danger Pay: +$225/month.
• Family Separation Allowance: +$250/month.
• Hardship Duty Pay: +$50-$150/month depending on location.
• Savings Deposit Program: $10,000 deposited earns about $1,000 over a year at 10%.

The cash entitlements alone add roughly $525-$625 per month on top of base pay, the tax break adds several hundred more in take-home, and SDP layers on a guaranteed return. For many members a single deployment is the fastest way to wipe out debt or build an emergency fund.

What keeps paying out: BAH and BAS

Your allowances do not pause when you deploy. Basic Allowance for Housing (BAH) generally continues at your home-station rate so your family keeps a roof over their heads, and Basic Allowance for Subsistence (BAS) continues as well. Because these allowances are already tax-free, they simply keep flowing while the deployment special pays stack on top. For more on the full menu of military special pays, see our special pays guide, and if a deployment is bookended by a move, our PCS resources cover the relocation side.

Make the most of the money

A deployment is a rare window where your income jumps and your expenses often fall. Maxing the SDP, banking the tax savings, and steering the extra pay into the Thrift Savings Plan can compound into a serious long-term advantage — especially under the Blended Retirement System, where government matching rewards every dollar you contribute. Always confirm your specific entitlements with your finance office or DFAS, since combat-zone designations and rates can change.
