Texas Voters Approve $140,000 School Homestead Exemption — What It Means for San Antonio Homeowners

Texas voters sent a clear message at the polls this week. Proposition 13, which raises the school district homestead exemption from $100,000 to $140,000, passed with nearly 80 percent of the vote — 2,348,815 Texans in favor, 609,203 opposed. That kind of margin doesn't happen by accident. It reflects how seriously homeowners across the state take property tax relief, and how much they've been waiting for it.

Here's what the change actually means. The school homestead exemption reduces the taxable value of your primary residence for school district tax purposes. Before Prop 13, the first $100,000 of your home's market value was already shielded from school district taxes. Now that protected amount rises to $140,000. The difference — that extra $40,000 — is no longer on the table when your school district calculates what you owe.

For homeowners in San Antonio, this matters a great deal. Bexar County falls within multiple school districts, including San Antonio ISD, Northside ISD, North East ISD, South San Antonio ISD, Judson ISD, East Central ISD, Southwest ISD, and Edgewood ISD, among others. Each of those districts levies its own tax rate, so the dollar value of this exemption increase will vary depending on where you live. But across the board, a larger exemption means a lower taxable value, and a lower taxable value means a smaller school tax bill.

To put it simply: if your home is appraised at $300,000, your school district was previously taxing $200,000 of that value (after the old $100,000 exemption). Under Prop 13, they'll now tax $160,000. That $40,000 reduction in taxable value works directly in your favor every year this exemption remains in place.

Homeowners who live in their property as their primary residence qualify for the homestead exemption. That includes folks in established neighborhoods like Alamo Heights, Helotes, Leon Valley, Converse, Schertz, and Windcrest, as well as those in newer communities in areas like Stone Oak, Cibolo, and Selma. If you've already filed your homestead exemption with the Bexar Appraisal District, you don't need to do anything new to benefit — the updated exemption amount will apply automatically once it takes effect.

If you bought a home in 2025 and haven't yet filed your homestead exemption, now is a good time to get that paperwork in order. You file with the Bexar Appraisal District, and the deadline to apply for the upcoming tax year is typically January 31. Getting that exemption on file means you'll be in position to benefit from the full $140,000 shield.

For buyers currently shopping in San Antonio, this is encouraging news. Lower ongoing property tax costs improve affordability over the life of a mortgage. Whether you're looking at a starter home in zip codes like 78227 or 78242 on the west or southwest side, or a larger home in 78258 or 78259 in the far north, the exemption applies to your primary residence regardless of price point. It won't change how lenders qualify you today, but it does affect your real cost of ownership going forward.

Sellers should understand that this exemption travels with the homeowner, not the home. When you sell, your buyer will need to establish their own homestead exemption after closing. It doesn't transfer automatically. That's worth mentioning during the sales process so buyers aren't caught off guard at their first tax bill.

Renters don't benefit directly from a homestead exemption — that protection is reserved for property owners who occupy their home as a primary residence. However, meaningful property tax relief for landlords can, over time, reduce the upward pressure on rents in some situations. It's not a guarantee, but it's part of the broader conversation around housing costs in a city that has seen significant rent increases in recent years.

For existing homeowners who are stretched by rising appraisals, this exemption increase is real, tangible relief. San Antonio's real estate market has seen strong appreciation, and with that appreciation has come higher appraisal district valuations. A larger exemption helps offset some of that burden without requiring homeowners to move or refinance.

The bottom line is straightforward. Texas voters approved Prop 13 by an overwhelming margin because property taxes are one of the most felt costs of homeownership in this state. An additional $40,000 in protected value for your primary residence is a meaningful step, and San Antonio homeowners across every school district in Bexar County stand to benefit.
