  • 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. more

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%.
