For the most accurate estimate, get the exact millage rate from your county assessor and override the rate field above.
How to use it
A two-minute guide.
The Home Value field is pre-filled with San Antonio's median home value of $260,000. Override with your actual home's market value for a specific estimate — your tax bill scales linearly with home value.
The rate is pre-filled with Bexar County's effective rate of 1.54% — the county-level average for owner-occupied homes, which is more precise than Texas's statewide average of 1.80%. Individual school districts and special taxing zones within San Antonio still shift the exact figure — if you know the rate from your latest tax bill, override it for the most precise estimate.
You'll see your estimated annual property tax, the monthly amount (which is typically escrowed with your mortgage payment), and a comparison to other states.
How it works
The math behind the result.
How San Antonio's tax bill works out. Homes in San Antonio are assessed and billed through Bexar County. The effective rate there averages about 1.54% of market value — below Texas's statewide average of 1.80%. On San Antonio's median home value of $260,000, that's approximately $4,004/year, or $334/month when escrowed with your mortgage.
How assessment works in Texas. Homes are appraised at full market value each January 1 by the county appraisal district. For homesteads, the appraised value used for taxes can't rise more than 10% per year.
Exemptions worth claiming. The Texas homestead exemption removes $100,000 of value from school-district taxes on your primary residence, with extra exemptions for homeowners 65+ and disabled veterans. Exemptions are the most common reason two identical San Antonio homes pay different tax bills — make sure yours are on file with Bexar County.
What property tax actually pays for. In San Antonio — like the rest of Texas — property tax funds local schools, public safety (police, fire), road maintenance, parks, libraries, and county government. Most of your bill stays in your county and school district.
Comparing to other states. Effective rates vary enormously across the US — from about 0.3% in Hawaii to nearly 2.5% in New Jersey. San Antonio's 1.54% puts it in the upper third nationally.
