  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

Iowa Property Taxes

Property taxes in the state of Iowa are a major source of revenue for local governments and services, including public schools. Taxes are collected annually, based on assessed property values that are recalculated every two years.

The state’s average effective property tax rate is 1.44%, which ranks as the 14th highest rate in the country. However, since rates are determined locally, property taxes varies greatly between cities and counties within Iowa. If you’re considering buying a home in Iowa, regardless of which county, check out our mortgage guide to learn about rates and the details of getting a mortgage in the Hawkeye State. Below, we will take a look at rates in every county and explain the most important property tax rules in Iowa.

How Iowa Property Taxes Work

Iowa property taxes are paid annually in two installments, due on September 1st and March 1st every year (though they are not considered late until the following month). Taxes are based on two factors: the assessed value of the property and the total local tax rate. Property values in Iowa are assessed every two years by county and city assessors.

Every county has its own assessor, as do ten cities. The assessor looks at market and property factors in order to determine the market value of the property. Assessed value, to which tax rates apply, is based on market value. The total statewide assessed value of residential property cannot increase by more than 3% annually. Thus, each year the state "rolls back" home values by applying a ratio calculated annually by the state's Director of Revenue. In 2014, that ratio was 55.7%. So if your home's market value was $100,000 (as determined by your local assessor), your assessed value would be $55,700.

There are a number of property tax credits and exemptions that can reduce the property taxes you owe. The most common is the Homestead Credit, which reduces your assessed value by $4,850. Other Iowa credits and exemptions include the Disabled Veteran’s Homestead Tax Credit, the Military Exemption and the Senior Citizens Property Tax Credit.

Iowa Property Tax Rates

Property tax rates in Iowa are determined annually depending on the budget requirements of local tax authorities and the total taxable value of property in a tax district. If taxable value increases one year and the budget requirements stay the same, tax rates will fall. If they decrease and requirements staythe same, tax rates will rise.

Tax rates are denominated in dollars per thousand. If your total tax rate is 20, that would mean you owe $20 in taxes for every $1,000 in assessed value. On a home with an assessed value of $200,000, the total tax bill would be $2,000.

The table below shows the average tax rate (in dollars per thousand) for every county in Iowa. It alsoshows the average effective tax rate. Effective tax rates are calculated by determining the median annual tax payments as a percentage of median home value.

Rank County Property Tax Rate School Rating Crimes Per 100k People

Methodology

Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we calculated the average math and reading/language arts proficiencies for all the school districts in the country. Within each state, these schools were then ranked between 1 and 10 (with 10 being the best) based on those average scores.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
