Effective rate = median real estate taxes paid divided by median home value. Source: U.S. Census Bureau, American Community Survey 5-year estimates (2023), tables B25103 and B25077.

Why county rates vary so much

Property tax is set locally, not by the state, so the rate depends on the county, city, school district, and special districts where a home sits, and on how those local budgets compare to local home values. A county with low home values can still have a high effective rate if its local budgets are large, and a wealthy county can have a low effective rate. The effective rate shown here is the median tax bill divided by the median home value, which is the standard way to compare places; your own bill depends on your assessment and any exemptions.
