Military Pay and Taxes: A Complete Guide (2026)

Published July 7, 2026 · 9 min read

Military compensation is not a single paycheck — it is a package made up of several components, some of which are fully taxable, and others that are completely tax-free. Understanding the difference is essential for service members who want to know what they are actually earning and how taxes affect their take-home pay.

This guide covers every major component of military pay, explains what the IRS considers taxable income, walks through a full worked example for an E-5 sergeant, and explains powerful tax benefits including the Combat Zone Tax Exclusion — one of the most significant tax breaks available to any American worker.

The Two Categories of Military Compensation

Military pay falls into two broad categories: pay (which is taxable) and allowances (which are generally not taxable). This distinction has enormous implications for how much federal and state income tax a service member actually owes.

*Special pay and bonuses earned in a designated Combat Zone are excluded from federal income tax. See the Combat Zone section below.

Basic Pay: The Taxable Core

Basic Pay is the foundation of military compensation. It is set by Congress and published in official pay tables maintained by the Defense Finance and Accounting Service (DFAS). Your Basic Pay amount depends on two factors: your pay grade (E-1 through E-9 for enlisted, W-1 through W-5 for warrant officers, and O-1 through O-10 for commissioned officers) and your years of service.

Basic Pay receives an annual Cost of Living Adjustment (COLA) each January. Here are approximate 2026 monthly Basic Pay rates for a selection of common pay grades: (DFAS.mil — Pay Tables)

Basic Pay is subject to federal income tax and FICA taxes (6.2% Social Security + 1.45% Medicare). It is also the income that gets reported in Box 1 of your W-2 at year-end — though the figure will be reduced by any pre-tax contributions you make to the Thrift Savings Plan (TSP).

BAH and BAS: The Tax-Free Allowances That Change Everything

For most service members, allowances make up a substantial portion of total compensation — and they are entirely excluded from federal income tax. The two largest allowances are:

Basic Allowance for Housing (BAH)

BAH covers the cost of off-base housing. It is set by location (Military Housing Area, or MHA) and varies significantly by duty station and dependency status. A service member living in San Diego, California with dependents might receive over $3,600/month in BAH, while someone at a rural installation in the Midwest might receive $1,200/month. None of it is taxable. (DoD BAH Calculator)

BAH is determined at the beginning of each calendar year based on local rental market surveys. Once set for a service member, it does not decrease even if local housing costs drop — this protection is called rate protection.

Basic Allowance for Subsistence (BAS)

BAS covers the cost of food. In 2026, the approximate monthly rates are:

• Enlisted: ~$473/month ($5,676/year)
• Officers: ~$320/month ($3,840/year)

Like BAH, BAS is completely excluded from federal income tax. It is also not subject to FICA. Service members who live in government quarters may receive a reduced BAS or have their BAS offset by the cost of the dining facility (DFAC) meals. (DFAS.mil — BAS rates)

Worked Example: E-5 Sergeant, 4 Years of Service

Let’s work through a complete tax picture for a realistic scenario: an Army Sergeant (E-5) with 4 years of service, married with one dependent, stationed at Fort Campbell, Kentucky.

Step 1: Total Monthly Compensation

Step 2: Federal Income Tax Calculation

Only Basic Pay is subject to federal income tax. The Sergeant files as Married Filing Jointly.

Step 3: FICA Taxes

FICA (Social Security + Medicare) applies only to Basic Pay — not to BAH or BAS.

Step 4: The Big Picture

This E-5 Sergeant earns $65,388 in total annual compensation but pays only $3,313 in federal taxes — an effective rate of just 5.1% on total compensation. A civilian earning $65,388 with no special allowances (filing MFJ) would owe roughly $6,200 in federal income tax and $5,002 in FICA, for a combined $11,202 in federal taxes — more than three times as much.

The key is that the non-taxable allowances (BAH + BAS = $29,616/year) are excluded entirely from the tax calculation. They function like pre-tax income that the IRS never touches.

The Combat Zone Tax Exclusion

The Combat Zone Tax Exclusion is one of the most powerful tax benefits in the entire US tax code. When an enlisted service member serves in a designated combat zone — even for a single day of a given month — their entire Basic Pay for that month is excluded from federal income tax. No income tax is due on pay earned during that month. (IRS — Combat Zone Tax Exclusions)

For commissioned officers, the exclusion is capped at the highest enlisted monthly pay rate (approximately $9,402/month for an E-9 with 38+ years of service in 2026). Officers earning above that cap still owe income tax on the excess.

The exclusion also applies to:

• Enlistment and reenlistment bonuses received while serving in a combat zone
• Imminent Danger Pay / Hostile Fire Pay earned in the combat zone
• All special pay types earned during combat zone service

Example: O-3 Captain, 6 Months in a Combat Zone

Consider an Army Captain (O-3) with 6 years of service (Basic Pay: $6,789/month), filing as single, who deploys to a combat zone for 6 months.

Both scenarios assume single filing status. Federal income tax calculated after $15,000 standard deduction.

Designated combat zones are established by Presidential Executive Order. Current zones include certain areas in the Middle East and the Sinai Peninsula. The IRS maintains a full list of designated combat zones and qualified hazardous duty areas. (IRS — Combat Zone Exclusions)

State Income Taxes on Military Pay

Federal tax law is uniform for all service members, but state tax treatment of military pay varies considerably. Some states are very generous to military members; others treat Basic Pay like any other income.

The key concept for military state taxes is domicile (your permanent legal home state) vs. duty station (where you are currently stationed). Under the Servicemembers Civil Relief Act (SCRA), a service member’s domicile does not change just because they are stationed in another state. You generally owe state income tax only to your home state — not to the state where you are currently posted. (MilitaryOneSource — Taxes for Military Members)

Spouses of service members also benefit from the Military Spouses Residency Relief Act (MSRRA), which allows them to maintain their home-state domicile for tax purposes even when living at the service member’s duty station in another state.

TSP: The Military’s Tax-Advantaged Retirement Account

The Thrift Savings Plan (TSP) is the military’s version of a 401(k). It allows service members to contribute pre-tax dollars from their Basic Pay into a retirement account, reducing their current-year taxable income just as a traditional 401(k) does.

In 2026, the TSP contribution limit is $23,500 (the same as the 401(k) limit for civilian employees). Service members aged 50 and older can make an additional catch-up contribution of $7,500. (TSP.gov — Contribution Limits)

Under the Blended Retirement System (BRS), which covers service members who entered military service on or after January 1, 2018 (or those who opted in), the government automatically contributes 1% of Basic Pay to the TSP, regardless of whether the service member contributes anything. If you contribute at least 5% of your own Basic Pay, the government matches up to 4% of that — meaning a total government contribution of 5%. This is free money that also reduces your taxable income.

Unique to the military: TSP contributions made from combat zone pay are excluded from federal income tax both going in (since the pay was already excluded) and coming out at retirement if placed in the Roth TSP. This makes Roth TSP contributions during deployment one of the most powerful retirement savings moves available to anyone in the US tax system.

Other Notable Military Tax Benefits

Several additional tax provisions apply specifically to military members:

• Extended filing deadlines: Service members deployed to a combat zone automatically receive at least 180 days after returning from the zone to file their federal tax return — with no late filing penalty. (IRS Publication 3)
• Moving expense deduction: Unlike civilian workers (who lost the moving expense deduction under the TCJA), active-duty military members can still deduct qualified moving expenses when they receive orders requiring a permanent change of station (PCS).
• Earned Income Tax Credit (EITC): Combat pay is non-taxable, but service members can choose to include it as earned income when calculating the EITC. This election can significantly increase the credit for lower-income service members. (IRS — Military EITC Rules)
• Free tax filing: All active-duty military members and their families qualify for free federal and state tax preparation through the IRS’s MilTax program (via Military OneSource) and VITA (Volunteer Income Tax Assistance) sites located on military installations.
• Death gratuity: The $100,000 death gratuity paid to the survivors of a service member who dies on active duty is entirely tax-free.

The Bottom Line

Military compensation is structured to deliver far more purchasing power than a comparable gross salary figure suggests. Because BAH and BAS are completely non-taxable, a service member’s effective federal tax rate on total compensation is often dramatically lower than what a civilian would pay on the same dollar amount.

The Combat Zone Tax Exclusion adds another layer of benefit that can eliminate months of income tax entirely. Combined with TSP matching under the Blended Retirement System, free healthcare, housing, and education benefits, the tax advantages of military service represent a substantial hidden benefit that is easy to overlook when comparing pay with the civilian sector.

For personalized guidance, service members should take advantage of MilTax or on-post VITA services, which provide free expert tax preparation from professionals who specialize in military-specific rules.
