The Notice of Appraised Value arrives, you open it expecting a modest bump, and instead the number has leapt by tens of thousands of dollars. For a Texas homeowner on a fixed income, that envelope can feel like a punch. The instinct is to panic about a tax bill that has not even arrived yet. The better move is to slow down, because a higher appraisal does not automatically mean a proportionally higher tax bill — and there are concrete steps that can blunt the increase.
Here is a calm, ordered plan for what to do when your appraisal jumps: understand what the number actually controls, check the protections you may already have, gather the evidence, and decide whether to protest. Most of it costs nothing but an afternoon.
First, separate the appraisal from the tax bill
Your appraised value is not your tax bill. The bill is the appraised value, minus any exemptions, multiplied by the tax rates that local school districts, cities, and counties set later in the year. A jump in appraised value can be partly or fully offset if those taxing units lower their rates, which the Texas Comptroller explains in its property-tax materials. So before you assume the worst, remember that the appraisal is one input, not the final answer. That said, a higher value usually does push the bill up, which is why the next steps matter.
Check whether the 10% homestead cap protects you
If the home is your primary residence and you have a homestead exemption on file, Texas law generally limits the increase in your taxable value to 10 percent per year, regardless of how far the market value rose. The Comptroller describes this homestead appraisal cap on its exemptions page. Look at your notice: it should show both a “market value” and an “appraised (capped) value.” If the capped value is the one used for your taxes, a dramatic market-value jump may not hit your bill nearly as hard as the headline number suggests. If you do not have a homestead exemption and the home qualifies, applying for one is the single most valuable thing you can do.
Confirm your exemptions are actually on the account
Exemptions reduce the value that gets taxed, and it is surprisingly common for them to be missing or dropped. Pull up your property on your county appraisal district’s website and verify that every exemption you qualify for is applied: the general homestead exemption, the over-65 or disabled-person exemption, a disabled-veteran exemption, and any local options your city or county offers. The state’s mandatory school-district homestead exemption was raised in recent legislation, and the Comptroller’s exemptions page lists what is available. A missing exemption is free money left on the table.
Pull the district’s evidence and your comps
If you decide to challenge the value, you need to know what the district based it on. Under Texas law you can request the appraisal district’s evidence packet, which often lists the comparable sales it used. Then gather your own:
- Recent sales of similar homes nearby that sold for less than your appraised value.
- Photos of anything that lowers value — roof age, foundation cracks, dated systems, a busy road behind the property.
- Repair estimates dated as of January 1, the appraisal date.
- Your closing statement if you bought recently for less than the appraised value.
Comparable sales are what appraisers respond to. A strong jump in your value paired with neighbors who sold for less is the most persuasive case you can make.
File a protest before the deadline
If the value looks too high, file a protest. The deadline is May 15 or 30 days after your notice was delivered, whichever is later, and it is printed on the notice. You file Form 50-132 or use your district’s online portal. Check both “value over market” and “unequal appraisal” as your reasons — they give you two independent paths to a reduction. Most protests settle at an informal meeting with a staff appraiser before ever reaching the Appraisal Review Board. The Comptroller walks through the steps in its protest guide.
If you are 65 or older, look at deferral
Texans who are 65 or older, or who are disabled, have an extra tool: under Texas Tax Code Section 33.06, you can defer collection of property taxes on your homestead. Deferral does not erase the tax — interest accrues, and the balance comes due when the home is sold or transferred — but it can stop a frightening appraisal jump from forcing an immediate cash crunch. Talk to your appraisal district about the affidavit before assuming a higher bill is unmanageable.
Watch out for “we’ll fix your taxes” pitches
A spike in appraisals reliably brings out solicitations promising guaranteed reductions for a share of your savings. Some firms are legitimate; others are not. The protest is free to file yourself, and the Texas Attorney General periodically warns Texans about property-tax solicitation schemes that mimic official notices. Before signing anything or paying a fee, confirm what you are actually getting and whether you could do the same thing for free.
Understand why the value jumped at all
Before you fight a number, it helps to know what moved it. Appraisal districts are required by the Texas Property Tax Code to value property at market value as of January 1, and in fast-growing parts of Texas, neighborhood sale prices can climb sharply in a single year. A wave of higher sales near you pushes up the district’s mass-appraisal model, and your value rises with it — even though nothing about your house changed. Other triggers include a recent sale of your own home, a new addition or major renovation that added square footage, or the loss of an exemption that had been holding your taxable value down. Knowing which of these drove your increase tells you whether to protest the value, restore a missing exemption, or simply rely on the homestead cap. The Comptroller explains the January 1 valuation standard in its property-tax materials.
Don’t ignore the rate-setting season
The appraisal is only half the story. Later in the year, your school district, city, and county hold public hearings to set their tax rates, and those rates — multiplied by your taxable value — produce the actual bill. Texas law requires these taxing units to publish proposed rates and hold hearings where the public can speak, and the state’s Truth-in-Taxation framework, described by the Comptroller, exists to make that process visible. A jumping appraisal paired with a rate that holds steady can still mean a higher bill, which is why paying attention to the rate hearings — not just the appraisal — is part of keeping the total in check. The appraisal protest is the spring fight; the rate is the late-summer one.
Mark May 15 on the calendar now
Of everything above, the one date that actually forecloses your options is the protest deadline — May 15, or 30 days after your notice was mailed, whichever falls later. Miss it and the value is locked in for the year regardless of how strong your comps would have been. The fix is procedural, not urgent: pull the notice out today, write the deadline on a calendar, and file Form 50-132 well before it, even if you are still gathering evidence. A protest filed with thin documentation and later supplemented at the informal meeting beats a strong case filed a day late. Everything else — the homestead cap, the missing exemption, the deferral affidavit — can be fixed any time; the protest window cannot.
