How Property Tax Works

Roseau County, Minnesota operates on a property tax system that funds essential local services including county government operations, schools, roads, and emergency services. Property taxes are calculated by applying tax rates to the assessed value of your property, minus any applicable tax credits. The county's effective property tax rate for 2025 is approximately 0.4689% for county purposes, though your total tax rate will be higher when including school districts, municipalities, and special taxing districts.

Your actual property tax rate varies significantly based on your specific location within Roseau County, as different areas are served by various school districts, cities, townships, and special taxing districts such as watershed districts or fire protection districts. The total combined rate typically ranges from 1.0% to 1.5% of assessed value. Properties are reassessed periodically by the county assessor to reflect current market values, and tax bills are issued annually with semi-annual payment options.

Supplemental Tax Bills

Supplemental taxes in Roseau County are additional property tax bills issued when there are significant changes to your property during the tax year. The most common triggers include new construction completion, property improvements that increase value, or changes in property ownership that affect classification or credits. When improvements are completed, the assessor determines the added value and calculates supplemental taxes based on the current tax rates for the remaining portion of the tax year.

For example, if you complete a $50,000 home addition in July and your total tax rate is 1.2%, the supplemental tax would be calculated as: ($50,000 × 1.2% = $600 annual increase) × (remaining months in tax year ÷ 12 months) = supplemental tax due. These supplemental bills are typically issued within 60-90 days of the assessment change and have separate due dates from your regular property tax payments.

Escrow & Property Taxes

Most mortgage lenders in Roseau County require property tax escrow accounts, where you pay 1/12 of your estimated annual property tax with each monthly mortgage payment. Your lender collects these funds and pays your property taxes directly to the county on the May 15 and October 15 due dates. Lenders typically conduct annual escrow analyses to adjust your monthly payments based on actual tax bills and any changes in assessed value or tax rates.

You can verify that your lender has paid your taxes by checking with the Roseau County Treasurer's office or accessing online payment records. If your property taxes increase due to reassessment or rate changes, your lender may require an immediate escrow shortage payment or spread the shortage over 12 months. When your mortgage is paid off, you become responsible for making direct tax payments to the county and should budget accordingly for the semi-annual due dates.
