How to Protest Your Property Taxes & Win
Every year, thousands of Texas homeowners overpay on property taxes simply because they don't know they can fight back. This guide gives you the tools, tips, and timeline to lower your appraised value — and keep more money in your pocket.

Even a small reduction in appraised value translates to hundreds — sometimes thousands — in annual tax savings.
Cap Future Increases
A lower base value limits how high your taxes can climb in future years under Texas's 10% homestead cap.
It's Your Legal Right
Texas law gives every property owner the right to challenge their appraisal. The system is designed for you to use it.
Do It Every Year
Values change annually. Protesting regularly ensures you're never overpaying as the market fluctuates.
⏰ 2026 Key Deadlines — Don't Miss These!
Missing the protest deadline means waiting another full year. Mark your calendar now.
Review Your Appraisal Notice
When your notice of appraised value arrives (typically in April), review the assessed value carefully. Compare it to what you believe your home is actually worth on the open market. Even if you don't receive a notice, you can look up your value at your county appraisal district's website (e.g., bcad.net for Bexar County, gcad.org for Guadalupe County).
File Your Protest Before the Deadline
You must file a Notice of Protest (Form 50-132) with your appraisal district by May 15 or within 30 days of your notice — whichever is later. You can file:
- Online through your county appraisal district's portal (fastest)
- By mail (postmarked by the deadline)
- In person at the appraisal district office
Gather Your Evidence
This is the most important step. Strong evidence wins reductions. You'll want to collect comparable sales (comps), photos of damage or issues, repair estimates, and any other proof that your home is worth less than the appraised value. See our evidence checklist below for details.
Attend Your Informal Hearing
Most protests begin with an informal meeting with an appraisal district staff appraiser. Come prepared, be professional, and present your evidence clearly. Many cases are resolved here without needing to go before the ARB. If you reach an agreement, get it in writing.
Attend the ARB Hearing (If Needed)
If you don't settle informally, you'll go before the Appraisal Review Board — an independent panel. Present your evidence professionally, be respectful, and make a clear ask for the value you believe is fair. The ARB panel makes a binding decision that day.
Accept, Appeal, or Escalate
If you're satisfied with the result, accept it. If not, you can still appeal to district court, binding arbitration, or the State Office of Administrative Hearings (SOAH) — though these options are typically best for higher-value properties or large disputes.
Comparable Sales (Comps)
Recent sales of similar homes in your neighborhood that sold for less than your appraised value. Use MLS data, Zillow, or HAR.com. Aim for 3–5 comps within the last 6–12 months.
Photos of Property Condition
Document any deferred maintenance, foundation issues, roof damage, outdated systems, or other defects that reduce your home's market value.
Licensed Appraisal or CMA
A professional appraisal or Comparative Market Analysis from a licensed real estate agent carries significant weight with appraisers and ARB panels.
Repair Estimates
Written contractor bids for necessary repairs show the cost burden a buyer would inherit and support a lower value.
Appraisal District Data Errors
Check your property record for mistakes in square footage, bedroom/bathroom count, lot size, or year built. Errors are more common than you'd think.
Neighborhood Sales Trends
If the local market has softened or prices have declined since January 1 (the appraisal date), document this with data to show the district is using stale values.
Always File — Even If You're Unsure
Filing a protest costs you nothing and preserves your right to negotiate. You can always withdraw later, but you can't file after the deadline has passed.
Focus on Market Value, Not Tax Bills
The ARB is deciding what your home is worth — not what your taxes should be. Frame your argument around comparable sales and market data, not what you can afford to pay.
Know Your "Magic Number"
Go in knowing the specific value you want. Don't just say "it's too high" — say "the value should be $XXX,XXX based on these three comparable sales."
Be Professional & Friendly
The informal appraiser has discretion to help you. Being prepared, polite, and organized goes a long way in getting a favorable result without escalating to the ARB.
Check Your Homestead Exemption
Make sure you've filed for your homestead exemption — it reduces your taxable value by up to $100,000 for school taxes and caps annual value increases at 10%.
Use a Real Estate Agent's Help
A local agent can pull comp data, help you build your case, and even attend hearings with you. As your advisor, Anthony Sharp can help you navigate the entire process.
Request the District's Evidence Package
After filing, you're entitled to request the appraisal district's evidence. Reviewing it lets you know exactly what they're basing their value on — and where to poke holes.
Keep Records Year Over Year
Save all your protest documents, evidence, and outcomes. Each year's base value affects the next, so a record of past successes strengthens future protests.
Consider Hiring a Property Tax Consultant
For higher-value homes or complex situations, a property tax consultant works on contingency — they only get paid if they save you money.
Missing the Deadline
This is the #1 mistake. Once May 15 passes (or your 30-day window), you lose your right to protest for the entire year. Set a calendar reminder now.
Showing Up Without Evidence
Simply saying "my taxes are too high" won't work. You need documented, market-based evidence to get a reduction. Come prepared with comps and photos.
Discussing What You Paid for the Home
Your purchase price is not directly relevant and can actually hurt your case if you paid above market. Stick to current market comparables.
Accepting the First Offer Too Quickly
At your informal hearing, the appraiser's first offer may not be their best. It's acceptable to counter with your own number backed by evidence.
Not Checking for Exemptions
Many homeowners are leaving money on the table by not claiming homestead, over-65, disabled veteran, or other exemptions they qualify for.
Forgetting to Protest Every Year
Property values are reassessed annually. Even if you won last year, you should review your notice and protest again if the new value seems too high.
