How Property Tax Works

Grand Forks County property taxes fund essential local services including schools, roads, law enforcement, fire protection, and other municipal services. The property tax system is administered at the county level, with taxes collected based on assessed property values and applicable tax rates. For 2025, the effective property tax rate in Grand Forks County is approximately 1.59%, though this represents a net effective rate that may vary based on individual property characteristics and available tax credits.

It's important to note that actual tax rates vary significantly by location within Grand Forks County due to special taxing districts. Properties may be subject to additional levies from school districts, city taxes, park districts, water districts, and other special assessment areas. Homeowners should verify their specific tax rate based on their exact location and applicable taxing jurisdictions. The county assessor's office can provide detailed information about which districts apply to your specific property address.

Section 4

Supplemental Tax Bills

Supplemental taxes in Grand Forks County are additional property tax assessments that occur when there are changes to a property's assessed value during the current tax year. Common triggers include new construction, completed home additions, changes in property ownership that reveal previously unreported improvements, or corrections to assessment errors discovered after the initial tax roll was completed.

When supplemental taxes are assessed, they are calculated by applying the current year's tax rate to the difference between the new assessed value and the original assessed value, prorated for the portion of the tax year remaining. For example, if a $100,000 home addition is completed in July (halfway through the tax year), the supplemental tax would be calculated as: ($100,000 × 1.59% tax rate × 0.5 years remaining) = $795. Supplemental tax bills are typically mailed separately from regular tax bills and have their own due dates, usually 30-60 days from the assessment date.

Example Calculation

Example 1 - $300,000 Home

  • Assessed Value: $300,000
  • Primary Residence Credit Applied: -$3,000 (requires application)
  • Net Taxable Value: $297,000
  • Annual Tax: $297,000 × 1.59% = $4,723

  • Assessed Value: $600,000
  • Primary Residence Credit Applied: -$5,000 (requires application)
  • Homestead Credit Applied: -$2,000 (income-qualified, requires application)
  • Net Taxable Value: $593,000
  • Annual Tax: $593,000 × 1.59% = $9,429
  • Monthly Escrow: $786

Example 3 - $1,000,000 Home

  • Assessed Value: $1,000,000
  • Primary Residence Credit Applied: -$5,000 (requires application)
  • Net Taxable Value: $995,000
  • Annual Tax: $995,000 × 1.59% = $15,821
  • Monthly Escrow: $1,318

Section 5

Escrow & Property Taxes

Most mortgage lenders in Grand Forks County require borrowers to establish an escrow account to ensure property taxes are paid on time. Your lender will collect approximately 1/12 of your estimated annual property tax bill each month along with your mortgage payment. The collected funds are held in escrow and used to pay your property taxes when they become due on April 15th each year.

Lenders typically conduct an annual escrow analysis to ensure adequate funds are being collected. If property taxes increase due to rising assessments or rate changes, your monthly escrow payment may be adjusted accordingly. You'll receive an escrow statement showing the calculation and any changes. It's important to review your annual tax statement and compare it with your lender's projections to ensure accuracy. If you pay taxes directly (without escrow), you're responsible for making the full payment by the April 15th due date to avoid penalties and interest charges.
