How Property Tax Works

Griggs County, North Dakota operates on a property tax system that funds essential local services including schools, roads, emergency services, and county government operations. Property taxes in Griggs County are calculated by applying various tax levies to the assessed value of real property, with North Dakota's base assessment rate of approximately 1% of market value serving as the foundation.

The effective tax rate in Griggs County varies significantly depending on your property's location within special taxing districts, including school districts, park districts, and other local service areas. Property owners should expect their actual tax rates to differ based on these district boundaries. The county follows North Dakota's standard assessment practices, with no statewide assessment cap limitations, meaning property values can increase without artificial restrictions based on market conditions.

Supplemental Tax Bills

Supplemental taxes in Griggs County are triggered when property undergoes significant changes during the tax year, such as new construction, major improvements, or ownership transfers that result in reassessment. These taxes represent the difference between what was originally assessed and the new assessed value, prorated for the remaining portion of the tax year.

For example, if you complete a $100,000 home addition in June, and your property is reassessed mid-year, you would owe supplemental taxes on the increased assessed value for the remaining months of that tax year. The calculation takes the difference in assessed value, multiplies it by your local tax rate, then prorates it based on the number of months remaining in the tax year.

Escrow & Property Taxes

Most mortgage lenders in Griggs County require property tax escrow accounts, collecting monthly payments along with your mortgage payment to ensure timely tax payments. Lenders typically collect 1/12th of your annual property tax bill each month, plus additional amounts to maintain required reserve balances.

Property tax payments in Griggs County are due in two installments: the first half by March 2nd and the second half by October 15th. Your mortgage servicer will make these payments on your behalf from your escrow account. You should receive an annual escrow analysis from your lender showing projected tax amounts and any required payment adjustments. If you pay taxes directly without escrow, you're responsible for meeting these deadlines to avoid penalties.
