If your Texas notice of appraised value looks high, you can protest to your county appraisal review board (ARB). In most cases the deadline is May 15 or 30 days after the appraisal district mails the notice, whichever is later. Start with the Comptroller's protest guide and Form 50-132, and ask your CAD about an informal conference before the formal hearing.

A protest is about the appraisal record for that tax year, not about how much you personally can afford. Bring evidence. Showing up to say "taxes are too high" without comps, photos or repair estimates rarely moves the board.

What is a Texas property appraisal protest?

County appraisal districts set market value for property tax purposes. If you disagree with the value, exemptions, special appraisal status or other entries on the record, Tax Code rules let you file a protest with the ARB for that county.

The ARB is a separate panel from the appraisal district staff. At a formal hearing, both you (or your agent) and the district present evidence. The ARB's order applies only to the tax year at issue. If you win, the chief appraiser notifies the taxing units, and any refund follows if you already paid.

You do not have to use Form 50-132. A written notice that identifies the property, the owner and what you disagree with is enough. Many owners still use the form because it is clear and widely accepted. If someone will speak for you, file Form 50-162 to appoint an agent.

When is the protest deadline?

For most owners, it is May 15 or 30 days from the date the appraisal district mails the notice of appraised value, whichever is later. The Comptroller stresses that the 30-day clock runs from the mailing date, not from when you open the envelope.

Residence homesteads are supposed to get notices by April 1, and other properties by May 1, or as soon as practical after that. In softer markets, some districts mail fewer notices. Bexar Central Appraisal District, for example, reminded owners in May 2026 that they could still protest by May 15 even without a mailed notice, and that values could be checked online.

Offshore workers and full-time military members may have late-filing options. There are also limited late paths for failure to receive a required notice, large value errors (generally one-fourth high on a homestead, or one-third high on other property, with taxes paid on the undisputed portion), clerical errors, and agreed corrections with the chief appraiser. Do not count on a late path if you can still meet the regular deadline.

How should you prepare for the hearing?

Request an informal conference with the appraisal district first if one is offered. Many protests settle there. If not, you go to the ARB.

The ARB must send hearing details at least 15 days ahead. At least 14 days before the hearing, the district must send the Taxpayer Assistance Pamphlet, the ARB hearing procedures, and notice that you can request the evidence the district will use. Read those procedures. They control how many copies of evidence you need and whether you can appear in person, by phone, by video or by affidavit.

Evidence that actually helps includes:

• Photos of your property and of comparable sales
• Repair estimates or receipts for needed work
• Closing statements, listings or other sale-price docs
• Median-level or unequal-appraisal calculations if that is your claim
• Surveys, engineering reports, deed records or affidavits when relevant

Present a clear case. The ARB cannot adjust value based on your personal finances. General market conditions can matter; your private hardship does not. Be on time. Treat the hearing like a court proceeding even when the tone is informal.

After the order, you can appeal to district court within 60 days in many cases, or in some situations use regular binding arbitration or (for higher-value properties) the State Office of Administrative Hearings. Those paths have deposits, filing rules and partial-tax payment requirements. Talk to a Texas property-tax professional or attorney before you escalate.

How does a protest relate to your homestead exemption?

They are different tools on related bills. The homestead exemption reduces taxable value if you qualify and apply. A protest challenges whether the appraised value (or other appraisal record items) is correct for that year. You may need both.

If you have not filed for the Texas homestead exemption yet, do that on the CAD's exemption track while you decide whether to protest value. And if you are buying or selling into a market with more listings, our fall 2026 Texas housing market overview helps separate MLS asking prices from CAD appraised values.

CAD values and recent sale prices are not always the same thing. Use local sales that match your home's size, age, condition and location when you build a protest file.

FAQ

Do I need a lawyer or tax agent to protest?

No. Owners can protest on their own. Many hire agents or attorneys for complex properties. If you appoint someone, file Form 50-162 so the ARB and district know who represents you.

What if I never got a notice in the mail?

You can still protest. Check your value on the CAD website and file by the usual May 15 / 30-days-after-mailing rule for your situation. Some districts, like Bexar CAD in 2026, publicly reminded owners that a mailed notice is not required to protest.

Can renters protest?

If your lease requires you to pay the owner's property taxes, you may protest the value when the owner does not. The owner still gets the notice and must forward a copy for leased real property in the situations the Tax Code covers.

What happens if I miss the deadline?

You may lose the regular protest right for that year unless a late-filing rule applies (good cause, failure to receive notice, large value errors, clerical corrections, or an agreed joint motion). Pay undisputed taxes on time so you do not lose other remedies.

Will a protest automatically lower my tax bill?

Only if the ARB (or a later appeal) lowers the value or fixes the record, and only for that tax year. Tax rates are set by taxing units later. A lower appraisal is still the main lever most owners have in the spring.

Next step

A licensed local real estate agent can help you pull recent comparable sales, read your notice of appraised value in plain terms, and decide whether a protest file is worth building before the deadline for your county.
