What the Texas Homestead Exemption Actually Saves You

I get asked about the homestead exemption more than almost anything else, and I have noticed something. Most homeowners know they are supposed to file one. Very few know what it actually does to their bill.

That gap costs people money, because the exemption only cuts one part of your taxes, and the part it cuts is not the part most folks assume.

The short version

If the home is your primary residence, Texas exempts the first $140,000 of value from your school district taxes. Not your city taxes. Not your county taxes. Just the school district portion. It is free to file, you only file once, and if you missed it you can generally go back two years and get a refund.

The one thing almost everyone gets wrong

Your property tax bill is not a single tax. It is several taxing units stacked together: the school district, the county, the city, and sometimes a hospital district, a community college, or a special district.

The homestead exemption you hear about applies to the school district line only.

That matters because the school district is usually the biggest single piece of the bill, so the exemption is genuinely valuable. But it is not a $140,000 reduction off everything. Your city and county still tax the full value.

Here is the shape of it. On a home appraised at $400,000 with the standard exemption, the school district taxes you on $260,000 while the city and county still tax you on the full $400,000. Two different numbers on the same bill, same house.

This is exactly why I built our free mortgage calculator to split those rates apart instead of blending them. Most calculators online apply one flat tax rate and then subtract the exemption from the whole thing, which produces a number that is simply wrong for Texas.

What changed in 2025

Texas voters approved Proposition 13 in November 2025, raising the school district homestead exemption from $100,000 to $140,000.

Two details worth knowing:

• It was retroactive to the 2025 tax year. The election was in November, but the change applied back to January 1, 2025. If you looked at a 2025 bill and something seemed off, that is likely why.
• Owners 65 or older and disabled owners got more. A companion measure added another $60,000 on top, for $200,000 total against school district taxes.

Filing rules people get wrong

It is free. This is the one I want to shout. There is an industry of companies that mail official-looking letters offering to file a “designation of homestead” for a fee, usually somewhere between $50 and $100. The Texas Attorney General has issued a consumer alert about them. Appraisal districts say it plainly: there is no fee to file directly with them. If a letter arrives asking for money to claim your exemption, throw it away and file yourself.

The deadline is before May 1, so April 30 in practice.

You can file late. This is the one that gets people money back. Texas requires the chief appraiser to accept a homestead application filed up to two years after the delinquency date. So if you bought in 2024 and never got around to it, you can likely still claim those years. Better still, the refund is automatic once the late application is approved. You do not file a second form to ask for it.

Buying mid-year no longer locks you out. It used to be that if you closed after January 1, you waited until the next year. Since 2022, a buyer who acquires after January 1 can receive the general homestead exemption for the applicable portion of that year, as long as the previous owner did not already claim it. You need to apply before the first anniversary of your acquisition date.

You do not re-file every year. Once it is granted it stays until the property changes hands or you stop qualifying. That said, appraisal districts are required to review every homestead at least once every five years, so if a re-application request shows up in the mail, open it. Tossing it can cost you the exemption.

The cap is a separate thing, and it has a trap

People blur the exemption and the appraisal cap together. They are different protections.

The cap limits how much your appraised value can rise: the lesser of market value, or last year’s appraised value plus 10 percent, plus the value of any new improvements.

Here is the trap. The cap does not protect you in your first year. It takes effect on January 1 of the tax year following the first year you qualified for the homestead exemption. So a buyer’s first full year is generally uncapped, and if you bought in a neighborhood that has appreciated hard, the jump can be startling. I have watched this catch people who budgeted off the seller’s old tax bill.

A related point: the cap applies to appraised value, not market value. The district keeps tracking market value separately, and the gap shows on your notice as a homestead cap loss. Your appraised value can keep climbing toward market value even in a year when prices went nowhere.

New improvements sit outside the cap too. A pool or an addition gets added on top. Ordinary repairs and maintenance do not, so a new roof or a water heater should not count against you.

Frequently asked questions

How much will the homestead exemption actually save me?

It depends on your school district’s rate, since that is the only rate it reduces. The state’s own estimate for the increase from $100,000 to $140,000 was somewhere in the range of a few hundred dollars a year for a typical homeowner. To see your real number, take the exemption amount, multiply it by your school district’s tax rate, and that is your annual savings on that line.

Does the homestead exemption lower my city and county taxes?

Not the state-mandated one. That is school district only. Separately, local taxing units are allowed to offer their own optional homestead exemption of up to 20 percent of appraised value, and some North Texas cities do while others do not. Two neighboring cities can treat the same house differently, so read each line on your bill.

I am 65 this year. What changes?

Two things. You get the larger school district exemption, and you become eligible for the over-65 school tax ceiling, which freezes the dollar amount of school taxes on your homestead at the level of your first qualifying year. The ceiling is also portable if you move, though it transfers as a proportion rather than a flat dollar amount, so ask your appraisal district for a tax ceiling certificate before you move rather than after.

What if I already sold and bought again this year?

File on the new home. The exemption and the cap attach to the property along with your qualification for it, and you do not inherit whatever the seller was paying.

Where to go from here

File it if you have not. Check whether you missed a prior year, because two years of refunds is real money and nobody is going to call and offer it to you.

If you are running numbers on a purchase, our mortgage calculator applies your county’s actual tax rates and handles the school district split correctly, so the tax line is not a guess. And if you want the longer version with the protest process, the MUD and PID charges that catch buyers in newer North Texas developments, and the over-65 and veteran rules, we put it all in the Texas property tax playbook.

One last thing, and I mean this. I am not a CPA or an attorney, and none of the above is tax or legal advice. Exemption questions get personal fast, especially around age, disability, and inherited property. Talk to your appraisal district, and talk to your own professional before you make a decision on anything unusual.
