Texas tax-after-buying calculator
Estimate a Texas home's first yearly property tax bill on the purchase price, with and without the school homestead exemption, from the Comptroller's adopted county, city and school-district rates.
Uses the Comptroller's 2025 adopted rates for the county, the city and Houston ISD.
Estimated first yearly bill
| Taxing unit (rate per $100) | No exemption | With a homestead |
|---|---|---|
| County (0.3810) | $1,524 | $1,524 |
| City (0.5192) | $2,077 | $2,077 |
| Houston ISD (0.8783) | $3,513 | $2,284 |
| Total | $7,114 | $5,884 |
Texas values a home at 100% of market value and the seller's cap on yearly increases ends with a sale, so this is the rate times the price. The homestead column takes the $140,000 school homestead exemption off the school district's taxable value only; a buyer generally qualifies from the first January 1 they own and live in the home, so the first bill after closing can have none. Not included: a city's or county's own homestead percentage, college, hospital, flood-control and emergency-services districts, and a municipal utility district (which can add $0.50 to $1.00 per $100). Exemption figures were last reviewed November 3, 2026. Confirm with the appraisal district.
