Assessor: Formula for Calculating Taxes

Assessed Value x Rollback - Military Credit (if applicable) x Tax District Levy - Credits/Exemptions (such as Homestead Credit) = Your Tax Bill

Example:
  • ($100,000 x 50%) - $1,852 x 0.0301234 - $100 = Tax Bill

  • ($50,000 - $1,852) x 0.0301234 = Tax Bill

  • ($48,148 x 0.0301234) - $100 = Tax Bill

  • $1,450.38 - $100 = Tax Bill
