Methodology
Every figure on this page comes from the U.S. Census Bureau's American Community Survey 5-year estimates. We store one row per county and roll counties up to state level, weighting each county by its population so that large metros are not treated the same as very small counties.
The median real-estate tax bill shown for a state is that population-weighted figure, not a simple average of county values. National comparisons use the same method across all states, so the state-versus-U.S. gap you see is a like-for-like comparison.
These are survey estimates, not transaction records, and they describe typical households rather than any individual situation. Nothing here is personalised financial advice.
The effective rate we show is our own calculation: median real-estate taxes paid divided by median home value in the same place. It is a comparison tool, not a millage rate, and it does not account for exemptions, caps or assessment lags.
