What is the property tax rate in San Antonio?

A typical San Antonio homeowner pays rates set by the City of San Antonio, Bexar County, a school district, Alamo Community College, the hospital district, and the San Antonio River Authority. The combined rate varies by school district. Use the escrow shock test to model the full bill at your specific address.

The Bottom Line Up Front
Your San Antonio property tax bill stacks rates from multiple taxing units. Using 2025 adopted rates, a homeowner in the City of San Antonio within NEISD pays a combined rate of roughly $2.25 per $100 before the homestead exemption. Within SAISD, the combined rate is higher at roughly $2.44 per $100. The $140,000 homestead exemption applies to the school district portion only. The exact bill depends on your assessed value, your school district, and which special districts cover your address.

How Your Bill Is Calculated
Your property tax bill is your assessed value, minus any exemptions, multiplied by the combined tax rate for your address. Here is a hypothetical example for a $350,000 home in NEISD with a homestead exemption filed.
- Assessed value: $350,000
- Homestead exemption, school portion: $350,000 minus $140,000 = $210,000 taxable value for NEISD
- NEISD school tax: $210,000 divided by 100 times $0.982200 = $2,062.62
- City of San Antonio tax: $350,000 divided by 100 times $0.541590 = $1,895.57
- Bexar County tax: $350,000 divided by 100 times $0.276331 = $967.16
- Alamo CC, Hospital, River Authority, Road and Flood: $350,000 divided by 100 times the combined rate of $0.467353 = $1,635.74
- Hypothetical total: approximately $6,561 per year, or $547 per month in escrow
This example is hypothetical. Every input is stated so you can adjust for your situation. Your actual bill depends on the Bexar Appraisal District’s assessed value for your property, which may differ from the purchase price. Use the escrow shock test to model the exact bill at any address.
Why School District Matters
The school district is the largest single rate on most San Antonio tax bills. The 2025 adopted rates range from $0.982200 for NEISD to $1.155200 for SAISD. That difference on a $350,000 home with a homestead exemption is roughly $363 per year. Verify which school district covers your target address before making an offer.
| School District | Rate per $100 | School Tax on $350K with Homestead |
|---|---|---|
| North East ISD | $0.982200 | $2,062.62 |
| Northside ISD | $1.004900 | $2,110.29 |
| San Antonio ISD | $1.155200 | $2,425.92 |
Taxable value for the school portion: $350,000 minus $140,000 homestead exemption = $210,000.

Frequently Asked Questions

How do I file for a homestead exemption in Bexar County?
File Form 50-114 with the Bexar Appraisal District. The deadline is April 30 of the year following your purchase. Filing is free and one-time. The exemption removes $140,000 from your assessed value for school district taxes.
When is the protest deadline?
May 15 or 30 days after your appraisal notice date, whichever is later, per Tax Code 41.44. File online, by mail, or in person with the Bexar Appraisal District.
Why is my property tax bill different from my neighbor’s?
Bills differ because assessed values differ. The Bexar Appraisal District sets each property’s value independently. Two homes on the same street may have different assessed values based on size, condition, age, and recent improvements. Exemptions also differ by owner status.
What is the 10% appraisal cap?
Under Tax Code 23.23, a homestead property’s appraised value cannot increase by more than 10% per year after the homestead exemption is filed. This cap applies to the appraised value, not the tax rate. Market values can rise faster than 10%, but the cap limits how fast your taxable value grows.
Do disabled Veterans pay property taxes in San Antonio?
Veterans rated 100% disabled by the VA pay zero property taxes under Tax Code 11.131. Veterans with partial disability ratings receive partial exemptions under Tax Code 11.22 based on their rating percentage. Surviving spouses may retain the full exemption.
How does San Antonio compare to Austin on property taxes?
Different cities, counties, and school districts make direct rate comparisons misleading. The Bexar County and Travis County rate stacks differ in structure. A home at the same assessed value may pay more or less depending on which taxing units cover it. See the Austin property tax guide for Travis County rates.
