Iowa has a relatively high effective property tax rate of 1.38%, ranking 9th nationally. The state relies heavily on property taxes to fund local services and schools, contributing to higher-than-average rates despite modest home values.
Iowa assesses property at 100% of actual value, with residential property taxed at a rollback rate set annually by the state to limit overall levy growth. The rollback creates a gap between assessed value and taxable value.
| Home Value | Estimated Annual Tax | Monthly (Escrow) |
|---|---|---|
| $250,000 | $3,450 | $287/mo |
| $203,200 (median) | $2,804 | $233/mo |
| $600,000 | $8,280 | $690/mo |
Iowa offers a homestead tax credit ($4,850 credit on the assessed value for owner-occupants), military exemption, and elderly/disabled tax credit program. Property owners can also apply for special agricultural valuations.
Iowa property taxes are due September 30 (first half) and March 31 (second half).
Linn County (Cedar Rapids) and Polk County (Des Moines) have the highest rates at around 1.5–1.6%. Johnson County (Iowa City) is also above average due to university town demand.
