How Property Assessment Works

Local governments assess properties at a fraction of market value using an assessment ratio, then apply a tax rate to that assessed figure.

Formula

Assessed Value = Market Value x Assessment Ratio

Annual Tax = (Assessed Value / 1,000) x Tax Rate per $1,000

Notes

  • Assessment ratios vary by jurisdiction, commonly between 50% and 100%
  • Tax rates are often expressed as mills (per $1,000 of assessed value)
  • Homestead exemptions may further reduce taxable assessed value

    • 计算示例

    A home has a fair market value of $400,000 with an 80% assessment ratio and a tax rate of $12 per $1,000.

    1. Assessed value: $400,000 x 80% = $320,000
    2. Annual tax: ($320,000 / 1,000) x $12 = $3,840
    3. Monthly tax equivalent: $3,840 / 12 = $320
