What San Antonio Home Buyers Need to Know About Texas Property Taxes

One of the most common things I hear from buyers relocating to San Antonio is some version of this: "I heard Texas has no state income tax — so housing must be pretty affordable, right?" And I always pause before I answer, because the full picture is a little more complicated than that.

Texas does not have a state income tax. That's absolutely true, and it's one of the reasons people are flooding into the San Antonio market from California, New York, Illinois, and beyond. But Texas funds its schools, roads, and public services through property taxes instead — and those rates can be a genuine shock if you haven't done your homework before closing.

I'm Scott C. Peck, Broker Associate and Business Development Director at JBGoodwin REALTORS® in San Antonio. I've helped over 120 buyers navigate this market, and property taxes are one of the most misunderstood pieces of the homeownership puzzle. Let me break it down for you the way I explain it to every client sitting across the table from me.

How Texas Property Taxes Actually Work in Bexar County

In Texas, your annual property tax bill is calculated by multiplying your home's assessed value by the combined tax rate for your specific location. In Bexar County — which covers San Antonio and surrounding communities — that combined rate typically includes levies from the county, the city or municipality, the local school district, and sometimes a hospital district or special utility district.

As of 2025–2026, effective property tax rates in San Antonio and Bexar County generally run between 2.0% and 2.7% of assessed value, depending on your exact location. Let's put that in real numbers: on a $400,000 home, you could be looking at $8,000 to $10,800 in annual property taxes. On a $600,000 home in a neighborhood like Alamo Heights or Terrell Hills, the bill can push well past $15,000 per year.

That surprises a lot of buyers — especially those coming from states where a 1% effective tax rate is considered normal. But here's the thing: once you understand how the system works and how to use it to your advantage, you can plan for it intelligently.

One important nuance: in Texas, the appraised value your county appraisal district assigns to your home is not necessarily the same as what you paid for it. The Bexar Appraisal District reassesses values annually, and your home's assessed value can rise significantly year over year — unless you take action to protect yourself. That's where exemptions come in.

The Homestead Exemption: Every San Antonio Buyer's First Move

The single most important thing you can do after closing on your San Antonio home is file for your homestead exemption with the Bexar Appraisal District. This is something I remind every single one of my buyers to do, and it's something a surprising number of homeowners miss or delay.

Here's why it matters so much: the Texas homestead exemption removes $100,000 of your home's assessed value from school district taxes — which typically represent the largest portion of your property tax bill. It also caps the annual increase in your home's assessed value at 10% per year, which is a significant protection in a rising market like San Antonio's.

To qualify, the home must be your primary residence as of January 1st of the tax year, and you must file your application with the Bexar Appraisal District. You can file at any point during the year of purchase, and the exemption applies retroactively to January 1st of that year.

Additional exemptions may be available depending on your circumstances. Seniors aged 65 and older qualify for an additional $10,000 school tax exemption and a tax freeze. Veterans with a disability rating of 100% may qualify for a complete property tax exemption on their primary residence — a benefit I always make sure my veteran clients know about when searching in areas like Converse, Live Oak, or Universal City near Joint Base San Antonio.

I also remind buyers to check whether the home they're purchasing had any prior exemptions. If the seller had a senior freeze in place, that protection does not transfer to you — and the tax bill for the new year will be recalculated at the full rate. This can meaningfully affect your monthly escrow payment.

How to Budget for Property Taxes Before You Make an Offer

Before I ever write an offer on a property, I pull the current tax bill and assessed value for my buyers. It's one of the first things I look at — because a home priced attractively can become significantly more expensive once you factor in a higher-than-expected tax rate.

When I'm working with buyers in neighborhoods like Stone Oak, Alamo Ranch, or the newer master-planned communities on the far north or west sides of San Antonio, I always check whether the subdivision is subject to a Municipal Utility District (MUD) or Public Improvement District (PID). These districts add a layer of taxes on top of standard rates — sometimes significantly — and they are not always prominently disclosed in listing marketing materials.

My advice: before you fall in love with a house, let me pull the full tax picture. Knowing what your monthly escrow payment will actually be — not just the principal and interest — is essential to making a sound financial decision. And knowing which exemptions you'll qualify for after closing can change your calculus on what you can comfortably afford.
