How to Prepare for a Texas Property Tax Protest Before Notices Arrive

Key Takeaways

• A protest is won on evidence gathered before the hearing, not on the argument that taxes feel too high.
• The deadline is May 15, or 30 days after the Notice of Appraised Value was delivered, whichever is later. Filing is free.
• Texas is a non-disclosure state, so appraisal districts estimate commercial sale prices, and a purchase year does not automatically set the value.
• Recent exemption increases lower a bill after the value is set, so an overstated value still costs money.
• Appeal windows after an Appraisal Review Board (ARB) order run from the date the owner receives notice of the order.

The Texas protest season has ended for 2026, and the next one begins when appraisal notices arrive in April. That gap is the best time to prepare. This checklist builds on the full Texas property tax protest guide and focuses on what owners can do before a notice arrives.

Start With What the Notice Actually Is

The number on the notice is the appraisal district’s opinion of a property’s value, produced by mass appraisal. Texas law gives owners a formal process to challenge it every year, and the protest deadline is May 15, or 30 days after the notice was delivered, whichever is later. The specific date is printed on the notice, and it is firm. Missing it narrows the options to late-protest grounds such as good cause, which are real but harder, and which generally close once the appraisal records are approved in mid-summer.

Knowing this in advance matters because the strongest protests start well before the notice does.

Build the Evidence File

What wins a protest is evidence. An ARB hears the argument that taxes are too high constantly, but it can only act on the argument that the value is wrong and a reason why. A useful file includes:

• Market comparables: recent sales of similar properties
• An equity analysis: the property’s assessment compared with the assessments of comparable properties
• Condition documentation: photographs and records of issues that reduce value
• Income and expense data: for commercial property, where income approaches apply

The guide recommends January through March for assembling this material, well ahead of the April notices.

Know What the District Is Guessing

Texas is a non-disclosure state, so appraisal districts are not privy to commercial sale prices. They estimate. A purchase year therefore does not automatically set the assessed value in either direction. If the assessment jumps past the purchase price, that gap can be challenged. If the purchase price was higher than the assessment, disclosure strategy matters, and advice is worth getting before a closing statement is handed to anyone.

Check the Exemptions First

Texas voters approved a package of relief amendments in November 2025:

• The school district homestead exemption rose from $100,000 to $140,000.
• The additional exemption for owners 65 and older, or disabled, rose from $10,000 to $60,000.
• The business personal property exemption rose from $2,500 to $125,000, starting in 2026, for qualifying tangible personal property used to produce income.

An exemption is subtracted from the appraised value, so the value still sets the starting point. Owners should confirm the appraisal district has applied the exemptions they qualify for, then test the value itself, because an overstated value still produces an overstated bill. Eligibility should be confirmed with the appraisal district.

Learn the Levels Before They Are Needed

A protest can escalate through four levels, and knowing them in advance prevents giving up early.

1. The informal meeting. Most districts meet with owners before any formal hearing, often by phone or online, and many protests settle here. An owner should know a walk-away value before the meeting starts.
2. The Appraisal Review Board. A panel of citizens, independent of the district’s appraisal staff, hears both sides. Owners can appear in person, by telephone, or by videoconference.
3. Binding arbitration, the State Office of Administrative Hearings (SOAH), or district court. An ARB order is not final. Binding arbitration is a faster, cheaper alternative to litigation, in which an independent arbitrator decides and the decision binds the district. The deposit is refunded, less a small administrative fee, if the arbitrator’s value lands closer to the owner’s opinion than to the ARB’s. SOAH hears value disputes on non-industrial property valued above $1 million, with notice of appeal due within 30 days of receiving the ARB’s decision. District court is the full remedy.
4. Next year’s cycle. Values reset annually, and the evidence file built this year is the head start on the next one.

Each route has its own filing window, and each runs from the date the owner receives notice of the ARB order, so the order itself should be checked for exact dates.

When Help Makes Sense

Plenty of homeowners handle a straightforward residential protest on their own, especially when the evidence is clear, and the amount at stake is modest. Representation tends to earn its fee in four situations: commercial property, where income approaches and equity analyses are in play; purchase years, where disclosure strategy matters; escalation after an ARB ruling, which is process-heavy; and portfolios, where hearing season compresses many files into a few summer months. A property tax consultant can handle that work.

One distinction applies to appraisal firms that also consult. When a firm appraises a property, it is independent and advocates for no one. When it consults on a protest, it advocates for the owner, using the same valuation expertise. They are two different assignments.

A Short Preparation Checklist

1. Locate last year’s notice and note the protest deadline it listed.
2. Confirm every exemption the property qualifies for is applied.
3. Gather recent sales comparables and an equity comparison.
4. Document the property’s condition, and for commercial property, assemble income and expense data.
5. Decide in advance what value would be acceptable at the informal meeting.
6. If an ARB order was received this year, check its appeal deadline now.

Deadlines and procedures follow the Texas Property Tax Code, and the notice and any ARB order control the dates that apply. Nothing here is legal or tax advice for a specific property, and no outcome is guaranteed.
