Pay your Hays County property taxes by January 31 to avoid penalties
Hays County mails tax bills in October. The deadline to pay without penalty and interest is January 31 of the following year. If you miss that date, you will owe extra fees on top of your tax bill.
Homeowners who are 65 or older, disabled, disabled veterans, or surviving spouses of disabled veterans may split payments into four installments: January 31, March 31, May 31, and July 31. Pay online, by mail, or in person at 712 S. Stagecoach Trail in San Marcos. The county also has substations in Kyle and Wimberley. Check hayscountytx.gov for current hours and locations.
