County plus school-district rate, in dollars per $100 of taxable value, before exemptions, from the published 2025 rates. Texas appraises a home at 100% of market value, so these rates apply to about the price; the seller's cap on yearly increases ends with a sale. A bill is the county rate (0.5239) plus the rate of the home's school district, plus a city's rate inside its limits. College, hospital, flood-control and emergency-services districts and any municipal utility district are not in these figures, and a district that crosses counties is listed under its home county. A homestead takes $140,000 off the school district's taxable value.
