Property Tax Calculator
Pick your state and county and enter your home's value to estimate your yearly property tax. The estimate uses the county's median effective rate — what local homeowners actually pay relative to their home values — so it already reflects typical exemptions.
How the estimate works
Annual tax ≈ home value × the county's median effective rate. The rate is the median real estate tax paid by homeowners divided by the median home value in the county (2019-2023 American Community Survey). Nationally it is 0.98%.
This is a fair average, but your bill can differ: assessed values often lag market prices, exemptions vary (homestead, senior, veteran), and rates change from one school district or city to the next. In Texas, North Carolina and Florida, the county pages have a detailed calculator that uses the official rate of each taxing unit and applies the state's homestead rules.
What raises or lowers a property tax bill
- Assessed value: set by the county assessor or appraisal district, usually as of January 1. You can appeal it if it is too high.
- Exemptions: most states reduce the taxable value of a primary residence; many give extra relief to seniors, disabled owners and veterans.
- Assessment caps: some states limit how fast a home's taxable value can rise each year (for example 10% in Texas, 3% in Florida for homesteads).
- Local rates: each county, city, school district and special district sets its own rate every year.
