Property Tax Exemptions You're Probably Not Claiming in Iowa

Iowa recently changed the math behind its general homestead credit, and separately overhauled its disabled veteran credit in ways that genuinely help some veterans and change the rules for anyone applying going forward. Both changes are already in effect, not proposals.

The general credit, now calculated differently

Every owner-occupied primary residence in Iowa qualifies for the Homestead Credit, which as of the current assessment year is calculated as 10% of the home's taxable value, with a floor of $5,500 and a ceiling of $20,000, adjusted annually for inflation. That's a different structure than a simple flat exemption: lower-value homes get bumped up to the $5,500 minimum, higher-value homes get capped at $20,000, and everything in between gets the straight 10%. File once with your county assessor by July 1; this is a permanent filing, not something you refile annually.

What stacks on top, if you qualify

Homeowners 65 or older can claim an additional $6,500 of taxable value exempt, on top of the general credit above, not instead of it. Separately, any honorably discharged veteran with at least 18 months of active duty service, regardless of disability status, can claim the Military Service Tax Exemption, worth $4,000 off taxable value, which also stacks with the general credit and the 65+ exemption. None of these require you to choose between them.

The one that changes everything, and a rule that just changed too

Veterans with a 100% permanent and total service-connected disability rating, or those paid at the 100% rate through Individual Unemployability, can claim the Disabled Veteran Homestead Tax Credit: a credit equal to the entire property tax levied on the homestead, effectively zeroing out the bill. There's no income limit, a restriction that was removed, and no cap on the home's value either. The trade-off is written directly into the statute: electing this credit means you can't also claim the Military Service Tax Exemption or any other veteran-specific real property exemption, though it doesn't affect the general homestead credit or 65+ exemption.

A newer rule changed how much land qualifies, and it depends on exactly when you applied. For applications filed on or after July 1, 2026, the credit is limited to a half acre, with no additional outbuildings included. If you applied before that date, you keep the older, more generous standard: a half acre within city limits, or up to 40 acres outside city limits, including outbuildings. A surviving spouse can continue an existing credit as long as they don't remarry or move, and even if the veteran never claimed it, a spouse or child receiving Dependency and Indemnity Compensation can apply for it in their own right.

What to actually check

Confirm your general Homestead Credit reflects the current 10%-with-floor-and-ceiling calculation, since it changed recently. If you're a veteran without a 100% rating, the Military Service Tax Exemption stacks with your other benefits; if you do have a 100% rating, compare it against the full Disabled Veteran credit, since you can't have both. And if you're applying for the Disabled Veteran credit for the first time after July 2026, know that the acreage limit is smaller than it was for people who applied earlier.
