How Property Tax Works

Morton County's property tax system funds essential local services including schools, roads, law enforcement, and county operations. Property taxes are calculated based on the assessed value of real estate multiplied by the applicable mill levy rate. The county follows North Dakota's standard assessment practices, with properties typically assessed at market value without a statewide assessment cap.

Tax rates in Morton County vary significantly by location within the county due to different combinations of special taxing districts, including school districts, city levies, park districts, and other special assessments. Property tax statements are mailed in December each year, with the primary payment deadline of April 1st. Additional payment options include installments due June 1st and August 1st for taxpayers who prefer to spread their payments throughout the year.

Supplemental Tax Bills

Supplemental taxes in Morton County are triggered by changes in property ownership, new construction, or significant improvements that occur after the annual assessment date but before the end of the tax year. These supplemental assessments ensure that property tax obligations are properly allocated between buyers and sellers during ownership transfers.

When supplemental taxes are levied, they are calculated based on the difference between the old and new assessed values, prorated for the remaining months in the tax year. For example, if you purchase a newly constructed home in Morton County in March that wasn't included in the January assessment, you would receive a supplemental tax bill covering the additional assessed value for the remaining months of that tax year. The county auditor issues supplemental certifications as needed, and payments follow the same schedule as regular property taxes.

Escrow & Property Taxes

Most mortgage lenders in Morton County require borrowers to establish an escrow account for property tax payments, especially when the loan-to-value ratio exceeds 80%. Your lender collects monthly escrow payments along with your mortgage payment, then pays your property taxes directly to Morton County when they become due.

Lenders typically collect escrow payments based on the previous year's tax bill plus a small cushion to account for potential increases. When Morton County mails property tax statements in December, your lender receives a copy and makes the payment by the April 1st deadline. You should verify that your lender has received the correct tax statement and that adequate funds are available in your escrow account. If you pay your own property taxes, remember that Morton County offers payment options on April 1st, June 1st, and August 1st.
