Is BAH taxable? No. The Basic Allowance for Housing is federally tax-free under 26 U.S.C. § 134, which excludes "qualified military benefits" from gross income. BAH doesn't appear on your W-2 as wages; it's paid as an allowance, not compensation.

That's the short answer. The longer answer covers a handful of state-level exceptions, how BAH interacts with the combat-zone exclusion, and — most valuable in day-to-day life — how mortgage lenders "gross up" your BAH when calculating your debt-to-income ratio for a home loan.

The statutory basis (IRC § 134)

26 U.S.C. § 134(a) reads: "Gross income shall not include any qualified military benefit." Section 134(b)(1) defines "qualified military benefit" as any allowance or in-kind benefit received by a member of the uniformed services that (a) was excludable from gross income on September 9, 1986, and (b) is received by reason of the member's status or service. BAH satisfies both conditions.

Because BAH is excluded at the definition-of-income level, it doesn't show up in W-2 Box 1 at all. It's not "reported and deducted" — it's simply not income.

State income tax

Most states follow the federal treatment: BAH is not income for state purposes either. The narrow exceptions are a handful of states that don't have a broadly-conforming income tax code or have historically taken a stricter reading. Even those states generally treat BAH consistently with federal rules for military filers — but the specific state form (or state DoR guidance) is the authority. If you're stationed in a state with income tax and unsure, check your state DoR's military tax bulletin, or use MilTax which handles state variations correctly.

If your state of legal residence is one of the nine no-income-tax states (Texas, Florida, Washington, Tennessee, Nevada, South Dakota, Wyoming, Alaska, New Hampshire), state treatment is moot.

CZTE + BAH interaction

BAH continues while you're deployed to a combat zone. Because BAH is already tax-free under § 134, the combat-zone exclusion doesn't create a "second" tax break for it — CZTE excludes base pay, not BAH. That's fine, because there was nothing to exclude in the first place.

Mortgage gross-up

When a lender qualifies you for a mortgage, they look at debt-to-income ratio (DTI). Your gross income drives the numerator; BAH counts, but BAH is tax-free, so lenders "gross it up" to reflect the pre-tax value that a taxable civilian income would need to equal it.

Standard gross-up on VA loans and most conventional lenders: 1.25×. A $2,000/month BAH grosses up to $2,500/month for DTI purposes. Some lenders will go to 1.30× or higher — always ask, because a higher gross-up can qualify you for a bigger loan.

BAH counted in the mortgage calculation must be:

FAQs

Is BAH reported on my W-2 at all?

Not in Box 1 (federal wages). It may show as "informational" in a memo box; some MPFs do, some don't. Neither approach affects your taxable income.

What about OHA (overseas housing allowance)?

OHA is treated the same as BAH: excluded from federal income under § 134.

Does BAH count for retirement or Social Security?

No. Because BAH is not "wages" for Social Security purposes, it's not counted for FICA or for retirement pay calculations. Retirement pay is calculated on "base pay" only.
