What San Antonio's 2026 Local Tax Increases Actually Cost the Average Homeowner

If you own a home in San Antonio, you have probably heard that several local taxing entities adjusted their rates this year. The numbers flying around can feel overwhelming, so let us break down exactly what changed, who it affects, and what it actually costs in real dollars.

Texas Public Radio reported that the City of San Antonio approved a tax rate increase that works out to roughly $36 a year — about $2.95 a month — for the average homeowner. That is a modest number on its own, and it is worth noting that homeowners who are 65 or older or who qualify as disabled and have a homestead exemption are protected: their city tax rates are frozen, so this particular increase does not hit them.

Bexar County took a different path. County commissioners held the tax rate steady and chose to cover a budget gap by drawing approximately $68 million from reserves rather than passing new costs along to property owners. For anyone who owns in unincorporated Bexar County — areas outside city limits that stretch toward places like Helotes, Converse, Von Ormy, and Live Oak — that is genuinely good news heading into fall.

The two increases that will be felt more broadly are from Alamo Colleges District and the San Antonio River Authority, known as SARA. Alamo Colleges raised its rate by 8.76 percent, bringing it to $0.167 per $100 of assessed value. SARA raised its rate by 5.46 percent. Neither increase is dramatic in isolation, but combined with the city's increase, they push the total added annual cost to around $129 for the average San Antonio homeowner, according to Texas Public Radio's estimate.

To put $129 in perspective: that is roughly $10.75 per month. It is not a budget-buster for most families, but it is real money, and it compounds with other rising household costs that San Antonio residents are already navigating.

Alamo Colleges District serves students across Bexar County through its five colleges — San Antonio College, St. Philip's College, Palo Alto College, Northwest Vista College, and Northeast Lakeview College. Its tax rate applies to property owners across most of the county, so whether you own in the South Side near Palo Alto or in the Stone Oak area in the north, this increase is likely on your bill.

SARA's jurisdiction covers the San Antonio River watershed, which runs through the heart of the city and into surrounding communities. Its rate increase funds flood control, environmental programs, and river maintenance — work that directly affects property values and livability in neighborhoods close to the river corridor, including the King William Historic District, Southtown, and communities further downstream.

If you are currently buying a home in San Antonio, these rate changes are worth factoring into your affordability calculations. When your lender estimates your monthly payment, property taxes are part of that picture. A combined increase of around $129 per year is not going to disqualify most buyers, but it is one more reason to look closely at the full tax bill on any home you are considering — especially if that home falls within multiple taxing entities with different rate histories.

Sellers should be aware that buyers are increasingly sophisticated about total monthly costs. In a market where buyers are already stretching to manage mortgage rates, a property tax bill that is higher than expected can be a sticking point. Being transparent about the current tax bill and homestead exemptions available to owner-occupants can help keep deals on track.

Renters are not directly on the hook for property taxes, but landlords who face higher tax bills often pass those costs along through rent increases over time. If you rent in San Antonio and have been wondering why rents have remained stubborn, rising property taxes are one piece of that puzzle.

For current homeowners, the most important action you can take right now is to make sure you have filed for every exemption you qualify for. The general homestead exemption reduces the taxable value of your home, and if you or your spouse are 65 or older or have a qualifying disability, additional exemptions and rate freezes apply. Filing is done through the Bexar Appraisal District, and getting that paperwork right can save you significantly more than any of this year's rate increases cost you.

The bottom line is that 2026 brought modest but real tax increases for most San Antonio homeowners, totaling around $129 per year when you add up the city, Alamo Colleges, and SARA. Bexar County's decision to hold its rate steady softens the blow. Whether you are buying, selling, or simply trying to budget for the year ahead, knowing these specific numbers gives you a clearer picture of what homeownership in San Antonio actually costs today.
