Defaults to the county's median home value. Your assessed value is on your assessment notice and is often lower than market value after exemptions.

Illustrative only. Estimates apply your county's median effective tax rate from Census survey data; your actual bill depends on your assessed value, exemptions, and the specific levies for your parcel. Confirm figures with your county assessor before making decisions.
Common questions
Frequently asked questions
How is my property tax bill calculated?
Your annual bill is your property's tax assessed value multiplied by the combined rate of every levy that applies to it: the county base levy plus school district, city, and special assessment district levies. The calculator applies your county's median effective rate — the median tax bill divided by the median home value from Census records — which reflects what owners actually pay after exemptions.
What is the difference between market value and assessed value?
Market value is what a buyer would pay for the property. Assessed value is the figure the assessor uses to calculate your bill, after exemptions such as homestead or senior exemptions and any state assessment limits, so it is often lower than market value. Your assessment notice shows both.
Why do effective property tax rates vary by county?
Each county sets its budget and divides it by the total taxable value in its jurisdiction, and school district and special district levies differ across county lines. That is why effective rates range from under 0.4% in parts of the South to over 2% in parts of Texas, New Jersey, and Illinois.
Can I lower my property tax bill?
Often, yes. Check that you are receiving every exemption you qualify for, and compare your assessed value to recent sales of similar properties. If the assessment looks high, every county has a formal appeal process with an annual deadline — your assessor's office publishes the date and the filing steps.
Do hotels and commercial properties pay the same rate?
Usually not. Homestead exemptions do not apply to commercial property, and many states assess commercial parcels at higher ratios, so a hotel often carries a higher effective rate than the county's residential median. The Commercial / hotel mode uses the Lincoln Institute's annual 50-State Property Tax Comparison Study, which benchmarks the effective commercial rate in each state's largest city at three property scales.
Where does the data in this calculator come from?
Residential medians are fetched live from the U.S. Census Bureau's American Community Survey 5-year estimates: median home values (table B25077) and median real estate taxes paid (table B25103) for owner-occupied homes, covering more than 3,100 counties. Commercial benchmarks come from the Lincoln Institute of Land Policy's 50-State Property Tax Comparison Study, published annually.
