How Does the Homestead Exemption Work in San Antonio? A Bexar County Guide for 2026

If you own and live in your home in Bexar County, the residence homestead exemption lowers the taxable value of that property, and for the 2026 tax year it removes $140,000 from the value your school district is allowed to tax. For most San Antonio homeowners that works out to roughly $1,400 to $1,820 in school tax savings every year, on top of a 20 percent reduction from both Bexar County and the City of San Antonio. You file once with the Bexar Appraisal District, and the exemption renews automatically for as long as the home stays your primary residence.

I am Scott C. Peck, Broker Associate and Business Development Director at JBGoodwin REALTORS, and the homestead exemption is the single most overlooked saving I see in San Antonio real estate. Buyers in Alamo Heights, Stone Oak, Olmos Park, and Alamo Ranch close on a home, get swept up in the move, and forget to file. A year later they are paying hundreds of dollars more than they owe. This guide walks you through what the exemption does, how to claim it, and what to do if a deadline has already passed.

How much does the homestead exemption save San Antonio homeowners in 2026?

The headline number is $140,000. That is the amount the exemption removes from your home's value before your school district applies its tax rate, and it has more than tripled in three years. Texas voters approved Proposition 4 in 2023, which raised the school exemption to $100,000, then Proposition 13 in 2025, which lifted it again to $140,000. At a typical San Antonio area school tax rate, that shields somewhere between $1,400 and $1,820 from your bill each year.

The school exemption is only part of the picture. Bexar County and the City of San Antonio each grant a 20 percent reduction of your appraised value once your homestead is on file, which compounds the savings. Homeowners who are 65 or older, or who qualify as disabled, receive an additional $10,000 school exemption and, just as valuable, a ceiling that freezes the school tax portion of their bill so it cannot climb even when values rise. For a couple downsizing from a larger Stone Oak home into a patio home near Alamo Heights, that ceiling can be the difference between staying comfortable and feeling squeezed by yearly increases.

There is one more protection worth knowing. Once your homestead is established, Texas law caps how much your assessed value can rise for tax purposes at 10 percent per year, even in a market where actual values jump faster. In neighborhoods like Mahncke Park and King William, where appreciation has been strong, that cap alone has saved my clients real money over time.

How do I apply for the homestead exemption in Bexar County?

You apply through the Bexar Appraisal District, known as BCAD, using Form 50-114, the Residence Homestead Exemption Application. You can complete it online through the BCAD website or submit the paper form by mail. You need to own the home and occupy it as your principal residence as of January 1 of the tax year, and the address on your Texas driver license must match the property address. There is no cost to file, and you only do it once. The exemption then carries forward year after year.

A few practical notes from closings I have handled. Update your driver license address before you file, because a mismatch is the most common reason applications get rejected. If you bought through a builder in a newer community such as Alamo Ranch, confirm the home was your residence on January 1, since new construction timing matters. And if you hold the property in a trust, you can still qualify, but the application asks for slightly different documentation. When in doubt, I am glad to point you to the right form and the right people.

What if I missed the April 30 deadline?

This is the question I get most often, and the answer is reassuring. The standard filing deadline is April 30 of the tax year, which for 2026 has already passed. The good news is that Texas Tax Code Section 11.431 lets you file late, and you can claim the homestead exemption retroactively for up to two prior tax years. If you bought your San Antonio home in 2024 or 2025 and never filed, you can likely recover that money. I have seen homeowners get refunds of well over a thousand dollars simply because they finally submitted the form.

Do not wait on this. Every year you delay is potentially a year of savings you cannot recover once you fall outside the two year window. If you are not sure whether your exemption is on file, you can check your status on the BCAD website in a couple of minutes, and I am happy to walk you through it.

Frequently Asked Questions

Do I have to reapply for the homestead exemption every year?

No. Once the Bexar Appraisal District approves your homestead exemption, it renews automatically for as long as the home remains your primary residence. You only need to refile if you move, the property changes ownership, or BCAD specifically requests verification.

Can I get the homestead exemption on a rental or second home in San Antonio?

No. The exemption applies only to your principal residence. A rental property, vacation home, or investment property does not qualify, and you can hold only one homestead exemption at a time in Texas.

How much is the over 65 homestead exemption in Bexar County?

Homeowners 65 and older receive an additional $10,000 school district exemption on top of the standard $140,000, plus a school tax ceiling that prevents the school portion of their bill from increasing. Many San Antonio seniors also qualify for added county and city reductions.

Property taxes are one of the largest ongoing costs of owning a home, and a few minutes of paperwork can protect thousands of dollars over the years you live there. Whether you just bought in Olmos Park, you are weighing a move within San Antonio, or you simply want to confirm your exemption is on file, I would be glad to help.
