PROPERTY TAX

CALCULATE YOUR TAX BILL

HOW TO CALCULATE CITY PROPERTY TAX:

The formula used to calculate property tax owed is Assessed Property Value (calculated at 40% of fair market value) minus exemptions (Basic Homestead, etc) multiplied by the millage rate.

Fair Market Value X 40% = Assessed Value – Exemptions X Millage Rate = Property Tax $100,000 x 40% = $40,000 – $2,000 x .006551 = $248.94

Stormwater fees are added on to property tax values for every residential and commercial property with an impervious area for a total amount due.        

City of Duluth exemption amounts are as follows:

  • Homestead              $2,000.00
  • Senior-65 or older   $2,000.00   (Income limit 25,000.00 per year)
  • 100% Disabled        $2,000.00
  • Disabled Veteran   $81,080.00
