Are BAH and BAS taxable? A pay item checker

The two tables that decide it

Publication 3 organizes military pay into two lists. Table 1 holds government pay included in gross income. Table 2 holds pay excluded from gross income. The tables are not exhaustive, and the publication says to see your return instructions for specific items. The excluded list applies whether the item arrives in kind, as a reimbursement or as an allowance.

BAH and BAS sit under Living allowances in Table 2, alongside the Overseas Housing Allowance and housing and cost-of-living allowances paid abroad by the U.S. or a foreign government. That is why neither is part of the taxable wages on a W-2.

What is taxable

Table 1 includes basic pay for active duty, drills, reserve and training duty, service school attendance and back wages. Special pay includes foreign duty, hardship duty, language proficiency, medical and dental officer pay and special duty assignment pay. Bonuses such as enlistment, reenlistment and officer bonuses are taxable, as is incentive pay for flight, submarine, hazardous duty and HALO. Under Other pay, the table lists accrued leave, CONUS COLA, high deployment per diem and the personal use of a government vehicle as an in-kind benefit.

The Table 1 heading adds a major qualifier: the items are included "unless the pay is for service in a combat zone." A bonus or special pay earned in a combat zone month can be excluded, subject to the officer cap described on our combat zone exclusion page.

What is not taxable

Beyond the living allowances, Table 2 lists moving allowances (dislocation, move-in housing, storage, temporary lodging), travel allowances including per diem, family allowances such as separation, uniform allowances, ROTC allowances, professional education, group-term life insurance, burial services and the death gratuity. In-kind benefits such as medical and dental care, commissary and exchange discounts, legal assistance and uniforms furnished to enlisted personnel are listed there too.

The BAH deduction question

The publication answers a common worry directly. Because BAH is excluded, one might think expenses paid with it cannot be deducted. It says the exclusion does not prevent you from deducting certain expenses paid with BAH, and that you may still deduct mortgage interest and real estate taxes on your home if you itemize and meet the usual rules. The Schedule A instructions are the place to check.

Easy mistakes

Differential wage payments from a civilian employer when you are on active duty for more than 30 days are taxable and are never treated as combat zone pay, even if you were in a zone. Hostile fire or imminent danger pay is in Table 1, and it is only excluded through the combat zone exclusion when earned in an eligible month. Listing those two correctly is where most people slip.

Another trap is assuming a lump of cash is tax free because it is called an allowance. The tables decide by item, not by the word allowance. A payment that is not on Table 2 is not excluded just because it arrives with your BAH.

A quick sorting rule

Ask three questions in order. Is the item a living, moving, travel, family or death allowance, or an in-kind benefit like medical care? Then it is probably in Table 2 and excluded. Is it pay for performing duty, a bonus, an incentive, or a cash payment that replaces civilian wages? Then it is probably in Table 1 and included. Was it earned in a month you served in a combat zone? Then the combat zone exclusion may remove it even though Table 1 lists it, within the officer cap if you are a commissioned officer.

The order matters because the combat zone rule overrides Table 1 but not the differential wage rule. A civilian employer's differential payment is taxable even for a person who was deployed in a combat zone.

Using the checker

Pick an item in the form above and the page returns which table it belongs to, plus the publication's note. If your item is not listed, the tables are explicitly not exhaustive. Check your return instructions or ask a preparer who handles military returns. The checker reads the lists as printed in the 2025 edition and does not track later changes.
