Pay Your Austin Property Tax Bill in December or January?

Should you pay your Austin property tax bill in December or January?

Austin-area property tax bills for 2026 are due by January 31, 2027, and penalties start February 1. Paying in December or January costs the same, but the tax year it counts in is different: a December payment generally counts toward your 2026 federal return and a January payment toward 2027. It only matters if you itemize, which is more realistic now that the SALT cap is $40,400 for 2026. If your lender pays from escrow, the timing is usually out of your hands.

Your 2026 property tax bill has probably already landed in your mailbox or your inbox. And every fall I hear the same question from clients: "Should I pay it now, or wait until January?"

The short answer is that it costs the same either way, as long as you pay by January 31. The longer answer is that the timing can change your federal taxes, and the rules changed this year in a way that makes it worth a second look.

When Austin property taxes are due (and what late costs)

The Travis County Tax Office says it plainly: "Taxes are due by January 31 of each year." Your 2026 bill covers the 2026 tax year, so the deadline is January 31, 2027.

If you miss it, the penalty and interest add up fast. Here's the Travis County schedule for a bill that isn't paid on time:

• February: 7% (6% penalty plus 1% interest)
• March: 9%
• April: 11%
• May: 13%
• June: 15%
• July: 18% (12% penalty plus 6% interest)
• After that, interest keeps adding 1% a month, reaching 24% by the next January

On a $9,000 bill, being even a few days late in February costs about $630. That's the number I'd want every homeowner to know before they decide to wait.

Travis County takes payments online, in person, by mail, by phone, and at drop boxes. Paying by card carries a fee of about 2.4%, and an e-check is $1.00. Williamson, Hays, and Bastrop counties follow the same January 31 deadline under state law, and each tax office lists its own payment options.

Why December vs. January can matter on your federal return

A property tax payment generally counts as a deduction in the year you actually pay it. So paying in December 2026 counts for your 2026 return, and paying between January 1 and January 31 counts for 2027.

That only helps you if you itemize. Two numbers decide that for 2026:

• The standard deduction: $32,200 for married couples filing jointly, $16,100 for single filers, and $24,150 for heads of household (IRS figures for tax year 2026).
• The SALT cap: $40,400 for 2026 ($20,200 if married filing separately). It phases down for incomes above $505,000, never below $10,000, and it's scheduled to drop back to $10,000 in 2030.

For years, the old $10,000 cap meant most Texas homeowners had no reason to itemize. Texas has no state income tax, so property tax is the big piece of state and local tax for most families here. With the cap at $40,400, a household with a sizable tax bill and a newer mortgage may now clear the standard deduction.

Here's a quick way to think about it:

• Add up your 2026 mortgage interest, the property taxes you'll pay in 2026, and your charitable giving.
• If that total is well above $32,200 (married filing jointly), paying your bill in December may be worth it, because it lands in a year where you're already itemizing.
• If it's well below, the timing probably doesn't change your taxes at all. Pay when it's easiest, just before January 31.
• If you're close to the line, ask your CPA about "bunching." Some owners pay one year's bill in January and the next year's bill in December, so two bills land in the same tax year.

If your mortgage has an escrow account

Most of my clients pay their property taxes through escrow. If that's you, your lender collects a little each month and pays the bill for you, and the lender decides when the payment goes out. You usually can't choose December or January.

What you can do:

• Check that it was paid. Look up your account on your county tax office site after the lender pays.
• Watch for your escrow analysis. If your bill or your insurance went up, your monthly payment can go up next year to catch up.
• Use Form 1098. Your lender reports the taxes it paid from escrow, and that's the year they count in.

What's on the 2026 bill this year

Your bill is a stack of separate rates: city, county, school district, and other districts like ACC or a MUD, each charged on your taxable value. A few of the 2026 rates already adopted:

• City of Austin: about 0.58 percent ($0.579948 per $100). The City estimated the typical Austin ratepayer pays about $9.48 a month more in city property tax this year.
• Travis County: about 0.386 percent, up 2.8% from last year (TaxDrop, October 2026).
• Williamson County: about 0.42 percent, the no-new-revenue rate.
• Hays County: about 0.41 percent.

Those are only pieces of the total. Your full rate depends on exactly where the home sits, which is why I always pull the real tax bill on an address before anyone makes an offer. Confirm your own situation with your CPA before you decide when to pay.

Frequently Asked Questions

When are Travis County property taxes due for 2026?

By January 31, 2027. Penalty and interest start on February 1, beginning at 7% and climbing to 18% by July.

Is it worth itemizing in Texas with no state income tax?

It can be now. The 2026 SALT cap is $40,400, so households with a large property tax bill plus mortgage interest may beat the $32,200 standard deduction for married couples. Run the numbers with your CPA.

If my lender pays my property taxes from escrow, can I choose the year?

Usually not. The lender pays from your escrow account on its own schedule, and the payment counts in the year it's made. Your Form 1098 shows the amount.

Can I pay Austin property taxes with a credit card?

Yes. Travis County accepts cards with a fee of about 2.4%, and e-checks cost $1.00. On a large bill, the card fee can wipe out any rewards.

What happens if I pay my Travis County taxes in February?

You'll owe a 7% penalty and interest on top of the bill. On a $9,000 bill, that's about $630.

The bottom line

Pay by January 31 no matter what. Whether you pay in December or January only matters if you itemize, and the new $40,400 SALT cap means more Austin homeowners should at least check.
