Bexar County has extended the 2025 property tax deadline to February 2 after changes at the U.S. Postal Service could make mailed payments appear late. Residents are advised to get proof of mailing or pay electronically to avoid penalties.
The Tax Assessor-Collector's Office processes payments based on the USPS postmark, not the day the check was dropped in the mail. Taxpayers can request a hand-stamped postmark or mail early to ensure their payment is received on time, according to the Bexar County.
Why The Deadline Changed
USPS has tweaked its operations so some mail gets its postmark when it hits a regional sorting facility, not when it leaves your neighborhood mailbox. That shift can quietly push the postmark date later than taxpayers expect, even if they did everything right on their end.
As reported by MySA, postal officials and local election and tax offices are all giving similar advice. If you are mailing anything time sensitive, they say to request a manual postmark, consider using certified mail, or at least hang on to your receipts so you can prove when you handed the envelope over.
How To Pay And What Counts
The county would really prefer you not gamble on the postmark at all. Officials are steering residents toward electronic payments, including online e-checks and credit card payments, along with a phone payment line at 1-888-852-3572 for anyone who would rather punch in numbers than stand in line.
If mailing a check is your only realistic option, the tax office urges you to get verifiable proof of mailing, such as a hand-stamped postmark at the counter or a postal receipt that clearly shows the date. For detailed payment instructions and what the county considers acceptable proof, check the payment information from Bexar County.
Drop-Off Options And Extended Hours
For those who prefer to drive over in person, local coverage says county tax offices will stretch their hours on Monday and set up curbside or drive-thru lanes to handle the last-minute rush. Downtown and several substations are expected to offer faster drop-off options so you can pass a check through a car window and be on your way.
KENS 5 lists which locations will have drive-thru service and how late each office will stay open, including specific downtown curbside hours and evening windows at select substations.
Legal Note
Before anyone blames a missing bill, state law comes down pretty hard. Under Section 31.01(g) of the Texas Tax Code, not receiving a tax notice does not excuse delinquency and does not affect the validity of the tax, the penalty, or the interest that piles on top.
Penalties on delinquent taxes can be steep, with late fees typically starting at 7 percent and additional interest potentially accruing on top of that from the moment the payment is considered late. The statute and typical penalty structure are broken down in coverage from the Express-News.
If you are already on a half, quarter, or 10-month payment plan, the February 2 deadline does not apply to you. Everyone else is on the clock and being urged to lock down proof of mailing or pay electronically so a stray postmark does not trigger that first-month penalty.
