Property Tax Calculator

Property tax is the single largest tax most homeowners pay each year, yet many people don't understand how it's determined. Your property tax bill is based on two key factors: your home's assessed value and the local tax rate (often called a mill levy). The assessed value is set by your county assessor and may be based on recent sales of comparable homes, the cost to rebuild your property, or the income it could produce.

Tax rates are set annually by local governments and special districts — including school boards, fire districts, and municipal agencies — that each levy their own portion. Your total tax rate is the sum of all these overlapping levies. For example, a county with a 0.5% base rate, a 0.8% school levy, and a 0.2% fire district levy would have a combined rate of 1.5%. On a home assessed at $350,000, that means an annual tax bill of $5,250.

The effective tax rate — the metric we use across TaxByCounty — is calculated by dividing the actual taxes paid by the home's market value. This is a more accurate comparison tool than the nominal mill levy because it accounts for differences in assessment ratios between states. Nationally, the average effective rate is 0.91%, meaning a home worth $211,574 would generate roughly $1,924 in annual property taxes.

Most homeowners can reduce their tax burden through exemptions. Homestead exemptions (available in most states) reduce the taxable value of your primary residence, sometimes by $25,000 to $50,000. Senior citizen, veteran, and disability exemptions offer additional reductions. If you believe your assessed value is too high, you have the right to file a formal appeal with your county assessor — a process that succeeds more often than most homeowners realize.
