San Antonio and Bexar County Property Tax Rates
Reviewed by Daniel Ortiz · Senior Property Tax Consultant · Last reviewed September 2026
There’s no single San Antonio property tax rate. Your bill is the sum of several rates, one from each taxing unit where your property sits: the city, the county, your school district, and a few others. Each one sets its own rate every year.
How Your Property Tax Bill Is Calculated
Each taxing unit applies its rate to your taxable value: the appraised value minus any exemptions that unit offers. Rates are stated per $100 of value.
Example: a rate of $0.50 per $100 on $300,000 of taxable value is $1,500 a year from that one unit. Add every unit on the bill to get the total.
Exemptions differ by unit. The $140,000 homestead exemption, for example, applies only to school district taxes, so the same home has a different taxable value on each line of the bill.

What “Effective Tax Rate” Means
People use the phrase two ways. In everyday use, it’s your total tax divided by your property’s market value: what share of the value you actually pay each year, after exemptions and caps. In Texas rate-setting, the old “effective tax rate” was renamed the no-new-revenue rate in 2019: the rate that would bring a taxing unit the same revenue from the same properties as last year.
How Tax Rates Are Adopted
Every summer, after the appraisal district certifies values, each taxing unit calculates two benchmark rates. The no-new-revenue rate would raise the same money from the same properties as last year. The voter-approval rate is the most a unit can adopt without an election. Most cities and counties can grow maintenance and operations revenue by up to 3.5% a year before voters must approve it, and they can carry forward unused room from recent years.
Units publish proposed rates in August and September and hold public hearings before adopting them. That’s the time to comment. Once the rate is set, the only part of the bill you control is the value.
Why Texas Property Taxes Run High
Texas has no state income tax and no state property tax. Schools, cities, counties, and special districts fund most of their budgets from local property tax, so rates here run higher than in most states. The state has used homestead exemptions and school rate reductions to offset some of it, but the burden still falls mostly on value.
What You Can Actually Lower
You can’t change the rate. You can make sure every exemption you qualify for is on your account, and you can protest the value every year. Value is where most of the savings are.
