Property taxes are a significant part of homeownership costs in San Antonio, Texas.


Understanding how they work, what they fund, and how they compare to nearby counties can help you plan your finances and potentially save money.


This guide breaks down everything you need to know about property taxes in San Antonio, including rates, exemptions, and strategies to manage your tax burden.


What Are Property Taxes?

Property taxes are annual taxes homeowners pay based on the assessed value of their property. These taxes fund essential public services like schools, roads, emergency services, and parks.


In Texas, property taxes are a combination of state, county, and local taxes, which means the rate you pay depends on where your property is located.


How Are Property Taxes Calculated in San Antonio?

Property taxes in San Antonio are calculated using the formula:


Taxable Value × Tax Rate = Property Taxes


Here’s how it works:

  • Taxable Value: The assessed value of your property after exemptions are applied.

  • Tax Rate: A percentage set by the taxing entities in your area, such as Bexar County, the city of San Antonio, and your local school district.


For example, if your home is valued at $250,000 and the total tax rate in your area is 2.2%, your annual property tax bill would be:

250,000 × 0.022 = $5,500

  • Homestead Exemption: Reduces the taxable value of your primary residence by $40,000 or more.

  • Senior Citizen or Disabled Exemption: Additional reductions for homeowners aged 65+ or those with disabilities.

  • Veteran Exemption: Tax reductions based on the homeowner’s level of disability from military service.

To apply for exemptions, you’ll need to submit an application to your county’s appraisal district by April 30 of the tax year.

Tips to Lower Your Property Taxes

Managing your property taxes effectively can save you money. Here are some tips:

  • Check Your Assessed Value: Review your property’s assessed value each year. If it seems too high, file a protest with the appraisal district.

  • Claim All Exemptions: Ensure you’re applying for every exemption you qualify for.

  • Consider Renovation Costs: Certain home improvements can increase your home’s value, which may raise your taxes. Plan upgrades wisely.

  • Work with a Tax Consultant: A professional can help identify strategies to minimize your tax burden.

How to Protest Your Property Taxes in San Antonio

If you believe your property has been overvalued, you can file a protest with the Bexar Appraisal District. This process allows homeowners to dispute the assessed value of their property and potentially reduce their tax bill. To begin, visit the Bexar Appraisal District's protest page. You'll need to provide evidence, such as:

  • Recent appraisals of your property

  • Comparable sales in your neighborhood

  • Photos or documentation showing the condition of your property

  • Protests must be filed by May 15 of each year or within 30 days of receiving your notice of appraised value. For detailed guidance on how to prepare for a hearing, check the Texas Comptroller's Guide to Protesting Your Property Appraisal.

Property Tax Exemptions: A Closer Look

Understanding and claiming the right exemptions can significantly lower your tax bill. For San Antonio homeowners, the most common exemptions include the Homestead Exemption, which reduces the taxable value of your primary residence, and the Senior Citizen Exemption for homeowners aged 65 and older.

To learn more about available exemptions and application deadlines, visit the Bexar County Appraisal District's Exemptions page. For veterans, the Disabled Veteran Exemption offers additional tax savings, based on the disability rating provided by the VA. Details about eligibility and the application process can be found on the Texas Veterans Commission website.

When Are Property Taxes Due in San Antonio?

Property taxes in San Antonio are typically due on January 31 of the following year. If you don’t pay by the deadline, penalties and interest will start to accrue.

Many homeowners pay property taxes through their mortgage escrow account, which spreads the cost across monthly mortgage payments.

What Happens If You Don’t Pay Property Taxes?

Failure to pay property taxes can have serious consequences:

  • Interest and Penalties: Unpaid taxes accrue interest at 1% per month and additional penalties.

  • Tax Lien: The county can place a lien on your property, which could prevent you from selling or refinancing.

  • Foreclosure: Persistent non-payment can result in foreclosure by the taxing authority.

To avoid these risks, it’s crucial to stay on top of your property tax payments.
