Property Taxes in Iowa: Rates, Exemptions, and How They Work (2026)
TL;DR
Iowa property taxes use a rollback percentage that reduces the assessed value before taxes are calculated. The residential rollback is approximately 46-54% (varies annually), meaning you pay taxes on roughly half of your assessed value. The average effective rate is about 1.43%. County assessors value property every 2 years. Iowa's Homestead Credit provides a flat dollar reduction. The Property Tax Credit for elderly and disabled provides additional relief. Appeal to the local Board of Review by April 30.
The Rollback System
Iowa adjusts assessed values using a "rollback" factor set annually by the state. The rollback limits the total growth of the statewide assessed value for each property class. The residential rollback has fluctuated around 46-55% in recent years. This means that on a home assessed at $300,000, you might pay taxes on approximately $150,000.
Assessment
County assessors revalue all property every 2 years (odd-numbered years for most classes). Values must be within 5% of market value.
