  • 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

Photo credit: ©iStock.com/christiannafzger

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 $1,322 annually in property taxes, almost $800 less than the national average.

One reason for the state’s relatively low property taxes is the homeowners exemption. This exempts half the value of owner-occupied primary residences from property taxes, up to a limit of $100,000.

A financial advisor in Idaho can help you understand how homeownership fits into your overall financial goals. Financial advisors can also help with investing and financial plans, including taxes, homeownership, retirement and more, to make sure you are preparing for the future.

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 is due on Dec. 20, and the second must be paid by 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 distinctive 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’s equal to 50% of the value of the house and one acre of land. The exemption is capped at $100,000 in 2019.

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 value of $75,000.

Idaho Property Tax Rates

Since local governments in Idaho can levy taxes at a number of different levels, 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 1.438%, while the rural rate is 0.951%.

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

Ada County

With a population of more than 435,000, Ada County is the most populous county in Idaho. The effective property tax rate here is 0.75%, which ranks as the 12th highest rate in the state.

In urban areas, such as the city of Boise, the average nominal tax rate is, on average, 1.35%. The rural rate is somewhat lower at 1.123%. 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.

If you have questions about how property taxes can affect your overall financial plans, a financial advisor in Boise can help you out.

Canyon County

Canyon County is in western Idaho, directly west of the city of Boise. It has the 4th highest average effective property tax rate in Idaho at 0.90%. This is the product of the county's 9th ranked $1,302 median property tax payment and 15th lowest $144,000 median home value.

Kootenai County

Located in the Idaho panhandle, Kootenai County has a 0.66% average effective property tax rate, which is lower than the rates in 22 other Idaho counties. This rate also compares favorably to state and national averages, which currently stand at 0.75% and 1.08%, respectively. Additionally, the county has a median home value of $212,900 and a median annual tax payment of $1,396.

Keep in mind, however, that the effective property tax rate incorporates all exemptions. This most notably includes the homeowners exemption, which can reach as high as $100,000 in 2019.

The homeowners exemption only applies to primary residences, though. So if you're looking to buy a second home or a vacation home on Lake Coeur d’Alene, you will not qualify and can therefore expect to pay higher rates.

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 $1,223 annually in property taxes. That's $100 less than the state average, and a sizable $860 below the national average.

Bannock County

The average effective property tax rate in Bannock County is 0.91%. That's the 3rd highest percentage in the state. At that rate, a homeowner with a home worth $150,000 would pay $1,365 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

Bingham County

The average effective tax rate in the county is 0.69%, but in certain urban areas, such as the city of Blackfoot, the average is somewhat higher at 2.238%. Those rates apply to net taxable value, however, which is assessed value minus any applicable exemptions.

Bonner 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 analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

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.
