County Tax Calc
Estimates only — for informational purposes. Arizona assessment ratios vary by property class. Verify your Limited Value and classification with your county assessor or the Arizona Department of Revenue.

Arizona Property Tax Calculator

Estimate your Arizona property taxes. Since 2015, all AZ taxes are levied against the Limited Value (LV). Enter your Limited Value, your property's assessment ratio (varies by class), and your county's tax rate.

The Formula

Annual Tax = Taxable Assessed Value × (Mill Rate ÷ 1,000)

Assessed Value = Market Value × Assessment Ratio (state-specific — see note below)
Mill Rate: 1 mill = $1 per $1,000 of assessed value. Enter your actual rate from your county tax bill.
