  • 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.

Idaho Property Taxes

Taxes on real estate in Idaho are relatively low in comparison with the rest of the country. The typical homeowner in the Gem State pays $1,276 annually in property taxes, about $920 less than the national average. One reason for the state’s relatively low property taxes is the homeowners exemption, which exempts half the value of owner-occupied primary residences from property tax up to a limit of $100,000. Read on to learn more about this exemption, other Idaho property tax rules and Idaho property tax rates.

How Idaho Property Taxes Work

Property taxes in Idaho are the primary source of funding for local services such as schools, parks, roads and law enforcement. You can pay taxes in two installments, the first due on Dec. 20 and the second due on June 20.

Taxes are based on the full market value of property, which is determined each year by an assessor in each county. In determining market value for a home, the assessor typically uses sales price data for recently sold homes that are comparable in terms of size, location, condition and other features.

Once assessed value has been determined, exemptions are applied. The largest exemption in Idaho is the homeowners exemption. You can be claim it on an owner-occupied primary residence, and it’ equal to 50% of the value of the house and one acre of land. The exemption is capped at $100,000 for the year 2018.

For example, if you own and live in a home with a market value of $150,000, your assessed value is $150,000. Your homeowners exemption would be $75,000 (half the value of the home), which means your tax rate will be applied to a total taxable value of $75,000.

Idaho Property Tax Rates

Since local governments at a number of different levels can levy taxes in Idaho, tax rates vary between counties, cities, school districts and other tax districts. Generally, tax rates within cities are higher than those in rural areas. The statewide average urban tax rate is 1.511% while the rural rate is 0.994%.

Those rates apply to taxable value and not market value. The effective tax rate is the median annual property tax rate as a percentage of median home value. It is useful for comparing rates between counties and with other states. The table below shows both the nominal and effective rate for every county in Idaho, as well as the median real estate tax payment.

Ada County

With a population of more than 420,000, Ada County is the most populous in Idaho. The effective property tax rate in the county is 0.77%, which ranks as the 11th highest rate of any Idaho County.

In urban areas, such as the city of Boise, the average nominal tax rate is 1.431% on average. The rural rate is somewhat lower at 1.170%. Keep in mind, however, that those numbers apply to net taxable value in Ada County. If you qualify for the homeowners exemption that could be as low as half of your market value.

Canyon County

Canyon County is in western Idaho, directly west of the city of Boise. It has the highest average effective property tax rate in Idaho at 0.94%. However, since Canyon County has the 12th lowest median home value in the state ($131,300), the median property tax payment is still below average at just $1,240 per year.

Kootenai County

Located in the Idaho panhandle, Kootenai County has property tax rates well below the state average. The average effective property tax rate in Kootenai County is just 0.69%. Keep in mind, however, that the effective rate incorporates all exemptions, including the homeowners exemption. That exemption only applies to a primary residence though, so if you are looking to buy a second home or vacation home on Lake Coeur d’Alene, you will not qualify and can expect to pay higher rates. Without exemptions the most recent average rate for the county is 1.150%.

Bonneville County

Bonneville County contains the city of Idaho Falls and is the most populous county in eastern Idaho. The typical Bonneville County homeowner pays $1,202 annually in property taxes. That is lower than the state average and is almost half the national average.

Bannock County

The average effective property tax rate in Bannock County is 0.92%. That is the third highest rate in the state. At that rate, a homeowner with a home worth $150,000 would pay $1,395 annually in property taxes. That amount will vary greatly between rural areas and cities, however. The average urban property tax rate in Bannock County is roughly double the average rural rate.

Twin Falls County

Twin Falls County is in southern Idaho, along the Nevada border. The county’s average effective tax rate is 0.82%, slightly above the state average. However, because the median home value in the county is lower than the state median home value, the median real estate tax payment is also lower. It is $1,226 per year.

Bingham County

The median annual real estate tax payment in Bingham County is just $1,031, about $250 less than the state average. The average total tax rate in the county is 1.6%. In urban areas, such as the city of Blackfoot, the average is somewhat higher at 2.156%. Those rates apply to net taxable value, however, which is assessed value minus any applicable exemptions.

Bonner County

Bonner County has the eighth lowest effective tax rate in the state of Idaho at just 0.56%. That is about half the national average. At that rate, a homeowner who has a home worth $210,000 (the median home value in the county) would pay about $1,175 per year in property taxes.

Nez Perce County

Nez Perce County is in eastern Idaho, along the border with Washington State. The county’s average effective property tax rate is 0.92%, which ranks as the fourth highest in the state of Idaho. The median property tax payment ranks third in the state at $1,551 per year.

Latah County

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.
