How Property Tax Works

Cavalier County, North Dakota operates under the state's property tax system with a base rate of approximately 1% of assessed value. Property taxes in Cavalier County fund essential local services including schools, county operations, emergency services, and infrastructure maintenance. The county conducts periodic countywide property tax reappraisals to ensure assessments reflect current market conditions.

Effective tax rates in Cavalier County vary by location within the county due to overlapping special taxing districts such as school districts, water resource districts, and municipal boundaries. Property owners may see different rates depending on which combination of taxing jurisdictions their property falls within. North Dakota does not impose an assessment cap, meaning property values can increase to full market value during reappraisal years.

Section 4

Supplemental Tax Bills

Supplemental taxes in Cavalier County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value mid-tax year. When these events occur, the county assessor calculates the difference between the old and new assessed values and applies the current tax rate to determine additional taxes owed.

For example, if you complete a $50,000 home addition in January and your property is reassessed, you would owe supplemental taxes on that increased value for the remainder of the tax year. The supplemental tax would be calculated as: ($50,000 increase × applicable tax rate) × (months remaining in tax year ÷ 12 months). These supplemental taxes are billed separately from regular property taxes.

Escrow & Property Taxes

Most mortgage lenders in Cavalier County require property tax escrow accounts for borrowers with less than 20% equity. Your lender collects monthly escrow payments along with your mortgage payment and pays your property taxes directly to the county when due. The lender estimates your annual tax liability and divides it by 12 for monthly collection.

Property taxes in Cavalier County are typically due in late spring, with specific due dates varying by year. Lenders usually pay taxes before the due date to avoid penalties. You'll receive an annual escrow analysis showing how your payments were used and any adjustments needed for the coming year. If your property taxes increase due to reappraisal or rate changes, your monthly escrow payment will be adjusted accordingly.
