  • 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.

What to Know About North Dakota Property Taxes

Property taxes in North Dakota are due on Jan. 1 of each year but are not considered late until March 1. Taxes paid by Feb. 15 receive a 5% discount on the total amount.

The property tax in North Dakota is an “ad valorem” tax, which means it is based on the value of the property to which it applies. Local assessors determine the true and fair value of property in their jurisdictions annually, generally through use of a mass appraisal, which relies on sales data and other factors.

The assessed value of all real property in North Dakota is equal to 50% of the market value. The taxable value is just a fraction of that – 9% for residential property. That means that for residential property, taxes are based on just 4.5% of the market value. So, for example, if your home is worth $200,000, your taxable value would be $9,000. Your total tax rate applies to that amount.

North Dakota Property Tax Rates

Homeowners in North Dakota face a single tax rate, which is the total of the rates levied by all the tax authorities in their area. This rate is expressed in mills. A mill is equal to 1/10th of a percent, or $1 of tax per $1,000 in taxable value.

Another way of calculating tax rates is as effective rates. An effective rate is the percentage of a home’s value paid annually in taxes, so if your home is worth $100,000 and you pay $2,000 annually in taxes, your effective rate is 2%.

The table below shows the average effective property tax rate for every North Dakota county, as well as their median home values and median annual property taxes paid.

Rank County Property Tax Rate School Rating Home Value Growth


Our study aims to find the places in the United States where people are getting the most value for their property tax dollars. To do this, we looked at property taxes paid, school rankings and the change in property values over a five-year period.

First, 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.

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.

Then, we calculated the change in property tax value in each county over a five-year period. Places where property values rose by the greatest amount indicated where consumers were motivated to buy homes, and a positive return on investment for homeowners in the community.

Finally, we calculated a property tax index, based on the criteria above. Counties with the highest scores were those where property tax dollars are going the furthest.
