What is O-4 BAH at Helena in 2026?

$3,039 per month with dependents ($36,468 per year), effective 01 JAN 2026. Without dependents it is $2,619 per month.

Does BAH count as taxable income?

No. BAH is excluded from federal taxable income, so a given BAH amount is worth more than the same figure in basic pay.

What happens if my BAH rate drops this year?

BAH rate protection holds you at the prior year's amount as long as your duty location, pay grade and dependency status stay the same. The lower rate applies to members arriving on new orders.

Promoting to O-5 here adds $192 a month. The pay chart moves this allowance far less than the map does.

Where you are stationed outweighs what you are paid. Moving from Helena to Westchester County at O-4 is worth $4,431 a month — about 23 promotions worth of housing allowance, at $192 per grade here.

Dependency status is worth 16% here. That is a status your finance office determines, not a box you tick — and it is the single largest lever on this page that is not a change of address.

None of it is taxed. $3,039 a month of BAH takes more than $3,039 of basic pay to match, which is why comparing a civilian salary against military base pay alone understates the gap.

Things the rate table doesn't tell you

“With dependents” is a dependency status, not a marital status. A single member paying child support can be authorized BAH-Diff; a married dual-military couple with no children is not automatically the with-dependents rate for both. If your situation is unusual, your finance office decides — not this table.

O-8, O-9 and O-10 draw the same BAH as O-7. The table stops there for a reason, not because it is missing rows.

This is CONUS BAH only. Overseas is OHA, which works differently — it reimburses actual rent up to a cap, with separate utility and move-in allowances. Alaska and Hawaii are BAH; Germany, Japan and Korea are OHA.
