Iowa homestead exemption
- From assessment year 2026, Iowa's homestead exemption takes 10% off a home's taxable value, at least $5,500 and at most $20,000, replacing the homestead credit; it first lowers the taxes due in September 2027 and March 2028.
- Owners 65 or older on January 1 of the assessment year get an additional $6,500 exemption of taxable value.
- Owners already receiving the homestead credit do not need to refile.
This is the property tax homestead exemption, not the homestead exemption that protects a home from creditors in bankruptcy.

Does Iowa have a homestead exemption?
From assessment year 2026, Iowa's homestead exemption takes 10% off a home's taxable value, at least $5,500 and at most $20,000, replacing the homestead credit; it first lowers the taxes due in September 2027 and March 2028. The calculator does not subtract it: the rates already reflect the exemptions owners received.
Why might a Iowa tax bill differ from this estimate?
The rate is what owner-occupiers in Iowa paid on average in 2020 through 2024, as a share of their homes' value. An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.
What the calculator leaves out
- The rate is the total real estate tax owner-occupiers reported paying divided by the total value they reported for their homes, not a tax rate set by law.
- The rate already reflects the exemptions, caps and credits typical owner-occupiers received, so the calculator does not subtract a homestead exemption again.
- An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.
- Survey estimates for small counties have wide margins of error.
Rates and medians are American Community Survey 2020-2024 5-year estimates: taxes owners paid in those years, not 2026 bills.
