The Short Answer
Active-duty military pay is fully exempt from Iowa income tax. Your base pay is set by the federal pay table — identical to every other state for your rank and years of service. What actually changes in Iowa is your BAH (averaging $1,100/mo without dependents and $1,400/mo with dependents) and how Iowa treats the taxable portion of your pay.

Here is how the math actually lands for a mid-career enlisted member stationed in Iowa, built the way I read my own LES. Base pay and BAS are federal; the Iowa BAH figure is the state average.
| Monthly line item | Amount | Taxable? |
|---|---|---|
| Base pay (E-5, over 6 yrs) | $3,874 | Yes (federal + state) |
| BAH with dependents (Iowa avg) | $1,400 | No — tax-free |
| BAS (enlisted) | $476.95 | No — tax-free |
| Gross monthly entitlements | $5,750.95 | — |
| Taxable income (base pay only) | $3,874 | — |
| Est. Iowa state income tax | varies — see notes | — |
Only the $3,874 of base pay is taxable — the $1,876.95 of BAH + BAS is completely tax-free. Run your exact rank, ZIP, and dependency status in the Military Pay Calculator for a precise estimate.
