Hays County property tax bills for the 2025 tax year are due on receipt and must be paid by Monday, February 2, 2026 to avoid penalty and interest. The Hays County tax bill due date normally falls on January 31, but because that day is a Saturday in 2026, the tax office has moved the last day to pay to the next business day. Delinquency begins February 3, 2026.1Hays County Tax Assessor – Collector. Hays County Tax Assessor – Collector
When Your Bill Should Arrive
Texas law requires the county tax assessor to mail each property owner a tax bill by October 1, or as soon after that date as practicable.2State of Texas. Texas Tax Code Section 31-01 – Tax Bills In Hays County, most statements arrive in early to mid-October, though with so many accounts across the county’s school districts, cities, and special districts, some envelopes take several weeks to reach every mailbox.3Hays County Texas. Hays County Tax Assessor – Collector
If nothing arrives by mid-December, don’t assume you’re off the hook. You owe the tax whether or not a bill reaches you, and penalties start on the same date either way. Look up your account at tax.co.hays.tx.us using owner name, property address, or account number; the site shows the current amount, exemptions on file, and a downloadable statement.1Hays County Tax Assessor – Collector. Hays County Tax Assessor – Collector Waiting for a lost envelope is one of the most common reasons people pay avoidable penalties.
Meeting the February 2, 2026 Deadline
For a mailed check, the USPS postmark decides the date. A metered stamp or printed online postage does not count as a valid postmark under Texas rules, so if you’re sending payment close to the deadline, take the envelope to the post office counter and ask the clerk to hand-cancel it. Electronic payments must be completed before the end of business on the last accepted day.
What Late Payment Will Cost You
Penalty and interest both begin on February 3 and climb every month the balance sits unpaid. Texas law adds a 6 percent penalty the first month of delinquency, then 1 percent more each month after that, while interest accrues separately at 1 percent per month. The combined additions run:
- February: 7% added (6% penalty + 1% interest)
- March: 9% added (7% penalty + 2% interest)
- April: 11% added (8% penalty + 3% interest)
- May: 13% added (9% penalty + 4% interest)
- June: 15% added (10% penalty + 5% interest)
- July: 18% added (12% penalty + 6% interest)
The penalty itself caps at 12 percent once July arrives, but interest at 1 percent per month keeps running as long as the balance remains unpaid.1Hays County Tax Assessor – Collector. Hays County Tax Assessor – Collector
There’s a second hit waiting in the summer. On July 1, taxing units that have contracted with a collections attorney can add an additional penalty of up to 20 percent to cover attorney fees. A $5,000 bill left unpaid into July can carry more than $1,900 in combined extra charges. Paying even part of the balance before February reduces the base those penalties are calculated on.
Quarterly Installments for Over-65, Disabled, and Disabled-Veteran Homeowners
If you’re 65 or older, have a qualifying disability, or are a disabled veteran or the unmarried surviving spouse of one, you can split your homestead taxes into four equal payments with no penalty or interest, provided the qualifying exemption is on file with the Hays Central Appraisal District and the property is your residence homestead.4State of Texas.

If Your Mortgage Company Pays From Escrow
When a lender pays your taxes from an escrow account, the tax office sends the bill to that lender, and the assessor is not required to send you a separate copy.2State of Texas. Texas Tax Code Section 31-01 – Tax Bills Your mortgage company is required to forward a copy to you within 30 days of receiving it. If you’ve refinanced or changed servicers recently, confirm with the tax office that the correct lender is on file. A mismatch can mean no one pays on time, and the penalties above still land on you.
