San Antonio property taxes in 2025

For those planning their finances, it’s important to understand the timing of property tax rates. In late 2024, the City of San Antonio set the rates for its 2025 fiscal year budget. As of early 2025, the City of San Antonio has maintained its property tax rate at $0.54159 per $100 of taxable valuation.

This rate is a combination of two components: a maintenance and operations rate of $0.33009 and a debt service rate of $0.21150. Despite a stable city tax rate, revenue will rise due to the Bexar County Appraisal District’s higher property values.

How does San Antonio calculate property taxes?

Two main factors determine property tax bill of San Antonio residents:

  1. The appraised value of your property, and
  2. The combined tax rates of the various local taxing entities. 

In essence, the appraised value represents the market value of your property as of January 1. The Bexar Appraisal District (BCAD) is responsible for appraising all taxable property in Bexar County each year.

From there, the total property tax you pay is calculated by multiplying your property’s taxable value (that is, the appraised value minus any exemptions) by the combined tax rate of all applicable taxing units.

For instance, these units include the City of San Antonio, Bexar County, one of the local independent school districts, and other special districts like the Alamo Colleges District and University Health System.

Important dates for San Antonio property taxes

Staying on top of key dates is crucial to avoid penalties. With that in mind, here are some important dates for San Antonio property owners:

  • January 1: Date of property appraisal by the Bexar Appraisal District.
  • Late April/Early May: Property owners receive their Notice of Appraised Value.
  • May 15: Deadline to file a protest of your appraised value with the Appraisal Review Board.
  • October 1: Taxing units set their tax rates for the year.
  • Month of October: Tax bills are mailed to property owners.
  • January 31 (following year): Last day to pay property taxes without penalty and interest.

Where do my property taxes go?

Because property taxes are a primary source of funding for essential local services, your tax dollars support:

  • Public Education: A significant portion goes to local independent school districts.
  • City Services: Funding for police and fire departments, street maintenance, parks, and libraries.
  • County Services: Supports county roads, courts, the sheriff’s department, and other administrative functions.
  • Healthcare: A portion contributes to the University Health System.
  • Higher Education: Supports the Alamo Colleges District.

What are the current San Antonio property tax rates?

As mentioned, the City of San Antonio’s tax rate for the 2024 tax year (used for the 2025 fiscal year) is $0.54159 per $100 of valuation. However, your total tax rate will be higher once all other taxing jurisdictions are factored in. 

The combined tax rate for a property in San Antonio can typically range from 2.0% to over 2.5%, depending on the specific school district and other taxing units.

Will property taxes in San Antonio rise this year?

While the City of San Antonio did not increase its tax rate, your individual property tax bill may still increase if your property’s appraised value has gone up. The Bexar Appraisal District reported a modest average increase of just over 2% in residential property values for 2025, with more significant increases for commercial properties.

It’s also important to be aware of potential statewide legislation. Texas voters will have the final say on proposed property tax cuts that could impact homeowners and businesses across the state, potentially offering some relief.

Nearby cities and their property tax rates

Property tax rates can vary significantly between municipalities. Here’s a look at how San Antonio’s city tax rate compares to some nearby communities. Note that these are city rates only and do not include county, school district, or other special district taxes.

These figures highlight that while San Antonio’s rate is competitive, the total tax burden is influenced by multiple factors beyond the city’s rate.

Becoming an expert on San Antonio property taxes

Staying informed about your property taxes is a key responsibility of homeownership. Be sure to review your annual appraisal notice carefully and consider filing a protest if you believe the valuation is inaccurate. The Bexar Appraisal District website is a valuable resource for information and forms. Additionally, the Texas Comptroller’s office offers comprehensive information on taxpayer rights and remedies.
