2026 Deployment Pay Calculator
Deployment Pay & SDP Calculator
Estimate what a deployment adds to your paycheck — combat zone tax exclusion (CZTE), hostile fire pay, hardship duty pay, family separation allowance, and Savings Deposit Program interest — computed from the current DFAS rate tables. Below is a default combat-zone example; set your own grade, station, and location profile in the interactive calculator.
Combat Zone Example: E-5 with 6 Years of Service
A Sergeant (E-5) with 6 years of service and dependents, home station El Paso, TX (Fort Bliss), deployed to a designated combat zone drawing CZTE, hostile fire pay, $100 hardship duty pay, and family separation allowance. An illustrative example — entitlements depend on your orders and location designations.
| Deployment Entitlement | Monthly |
|---|---|
| Hostile Fire Pay (HFP) | $225.00 |
| Hardship Duty Pay — Location (HDP-L, $100 tier) | $100.00 |
| Family Separation Allowance (FSA) | $300.00 |
| Extra Gross Pay per Month | +$625.00 |
Amounts come from the current DFAS special-pay tables via the shared pay engine. Basic pay, BAH, and BAS continue unchanged while deployed.
Military Deployment Pay & Tax Exclusions: Complete Guide
By MilPayGuide · Reviewed against official rate tables · October 2026
Serving in an operational deployment triggers specialized entitlements designed to compensate for physical risk, geographic hardship, and family separation. Combining statutory provisions from Title 37 (Pay and Allowances) and Title 26 (Internal Revenue Code Section 112), deployed service members often experience their highest net savings rate through combat zone tax exemptions, direct special pays, and the DoD Savings Deposit Program (SDP).
1. Combat Zone Tax Exclusion (CZTE)
Under 26 U.S.C. § 112, earnings in designated combat zones are excluded from federal income tax. Enlisted members and warrant officers enjoy unlimited tax exemption on all basic pay and special pays. Commissioned officers are exempt up to the highest enlisted pay rate plus $225 HFP. FICA payroll taxes (7.65%) still apply, but zero federal income tax is withheld.
2. Hostile Fire & Imminent Danger Pay
Under 37 U.S.C. § 310, HFP/IDP provides $225/month to members subjected to hostile fire or deployed to designated imminent danger areas. Hostile Fire Pay cannot be prorated—experiencing hostile fire even once entitles you to the full $225 for that month. When earned in a CZTE area, HFP is tax-free.
3. Family Separation Allowance (FSA)
Authorized under 37 U.S.C. § 427, FSA provides $300/month to members with dependents who are separated from their household for more than 30 consecutive days due to military orders. FSA is a non-taxable statutory allowance paid retroactive to day one of separation once the 30-day threshold is met.
4. DoD Savings Deposit Program (SDP)
Under 10 U.S.C. § 1035, deployed members can deposit up to $10,000 into the government SDP account, earning a guaranteed 10% annual rate compounded quarterly (10.4% APY). Depositing $1,000/month across a 9-month deployment yields roughly $380.66 in risk-free interest.
Frequently Asked Questions: Deployment Compensation
- How much extra pay do you receive during a military deployment?
- Total deployment compensation depends on the operational designations of your duty theater. In a designated combat zone, a typical deployment package adds: Hostile Fire Pay/Imminent Danger Pay (HFP/IDP) at $225/month, Hardship Duty Pay-Location (HDP-L) at $50 to $150/month, and Family Separation Allowance (FSA) at $300/month if separated from dependents for over 30 days. Most importantly, qualifying service triggers the Combat Zone Tax Exclusion (CZTE), eliminating federal income tax on your basic pay and special pays.
- How does the Combat Zone Tax Exclusion (CZTE) work?
- Under Internal Revenue Code Section 112 (26 U.S.C. § 112), military compensation earned while serving in a presidential-designated combat zone or qualified hazardous duty area is excluded from federal gross income. For enlisted personnel and warrant officers, 100% of basic pay, bonuses, and special pays are tax-exempt with zero cap. For commissioned officers, the exclusion is capped at the maximum enlisted basic pay plus $225 HFP (over $10,500/month in 2026). Under the statutory rule, serving even one qualifying hour in a combat zone during a calendar month exempts that entire month's compensation.
- How does the DoD Savings Deposit Program (SDP) work?
- Established under 10 U.S.C. § 1035, the Savings Deposit Program allows deployed service members to deposit up to $10,000 in unallotted pay into a guaranteed high-yield savings account. The program pays a statutory 10% annual interest rate compounded quarterly (10.4% effective APY). You become eligible to deposit funds after 30 consecutive days in the designated combat theater, and interest continues to accrue for up to 90 days after departure.
- Who qualifies for Family Separation Allowance (FSA)?
- Under 37 U.S.C. § 427, Family Separation Allowance provides $300 per month (payable at $10 per day) to service members with dependents who are separated from their family by military orders for more than 30 continuous days. FSA is a non-taxable statutory allowance that begins on the 31st day of qualifying separation, retroactive to day one.
- Are deployment pays and CZTE exempt from state income taxes?
- Most states follow the federal Internal Revenue Code and automatically exclude combat pay from state income taxation. Furthermore, many states (such as Pennsylvania, Ohio, and California) exempt all military compensation earned outside their borders on active duty, regardless of whether you are in a combat zone. Check your state of legal residence (SLR) rules to ensure accurate state tax withholding during deployment.
