HCAD just mailed your 2026 appraisal notice. Open it, look at the number, and decide in the next two weeks. The deadline to protest is May 15. Texans who file their protest win about half the time, and the average reduction is 8 to 12 percent. On a $400,000 home that is real money. $700 to $1,000 back in your pocket every year you protest.
This is the same evidence pack I assemble for my own home and for clients I closed last year. The whole filing takes about 15 minutes online. You do not need an attorney, and you do not need to pay a service a percentage of your savings unless you want to.
Deadline: May 15, 2026, or 30 days after your notice was mailed, whichever is later. Filing online through iFile is the fastest path. The protest is free.
What You're Protesting
You are not arguing your tax rate. The rate is set by the county, school district, city, and any special districts you sit in. You cannot change that. You ARE arguing the appraised market value of your home, which is the number HCAD multiplies by the rate. Lower the appraised value, lower the tax bill.
HCAD assesses your home using mass appraisal. An algorithm looks at sales in your zip code, applies a ratio, and assigns a number. The algorithm is conservative on purpose, but it is also imprecise on any one property. Yours might have flooded, might have a worse layout, might be smaller than the comp it got benchmarked against, and the algorithm did not know.
Who Should Protest
Almost everyone who owns a home in Harris, Fort Bend, Montgomery, Brazoria, or Galveston counties.
- Your appraised value went up. Even if it is "still under market," lowering the assessed value lowers your bill. The market value cap (10 percent for homestead-protected homes) means a low protest result this year compounds savings for years.
- Your home has condition issues. Foundation cracks, roof age, dated kitchens, deferred maintenance. None of this is in HCAD's algorithm. You document it.
- Recent comps closed below your appraisal. Three to five sales in your zip code in the last six months that closed for less than HCAD says your home is worth = your evidence pack.
- You bought the home in the last year for less than HCAD's number. A purchase price within the last 12 months below the appraised value is the strongest single evidence you can submit.
How Much You'll Save
It depends on how much you cut and your effective tax rate. Houston-area total tax rates run 2.0 to 3.5 percent depending on county, school district, MUD, and PID. Here is the math at average rate of 2.5 percent.
| Appraisal cut | Tax saved (year 1) | 5-year savings (10% cap rolls forward) |
|---|---|---|
| $10,000 | $250 | ~$1,400 |
| $25,000 | $625 | ~$3,500 |
| $50,000 | $1,250 | ~$7,000 |
| $75,000 | $1,875 | ~$10,500 |
The five-year number assumes you protest again the next time HCAD raises your value. The 10 percent homestead cap (your assessed value cannot rise more than 10 percent year over year while you have a homestead exemption) means a successful protest now compounds.
Step by Step: How to File in Harris County
1. Pull Your Notice
Find your appraisal notice in the mail (early to mid April) or look it up at hcad.org. You need your account number, which is on the notice or searchable by address. Note the "market value" and "assessed value" lines. Market value is what HCAD says the home is worth. Assessed value is what they actually tax (after the homestead cap).
2. Build Your Comp Pack
Pull three to five sold comparable homes in your zip code. Use HAR.com, Redfin, or Zillow. Filter for the last six months, similar square footage (within 15 percent), similar bedroom and bath count, similar year built (within 10 years). Take screenshots showing the closed sale price, the address, and the close date. This is your strongest single piece of evidence.
If you closed your home in the last 12 months for less than HCAD's market value, your closing disclosure is the comp. Include it.
3. Document Condition Issues
Walk your home with your phone. Photograph foundation cracks, roof wear (or send up a drone), water damage, dated bathrooms and kitchens, anything that lowers value compared to a "normal" home in your zip. If you have a recent inspection report, attach it. If you have a contractor's quote for repairs, even better.
4. Verify HCAD's Square Footage and Features
HCAD often has wrong square footage, wrong bath count, or wrong year built. Check the property card at hcad.org for your account. If they have you at 2,400 square feet and your appraisal district survey says 2,200, that is a 200 square foot error worth thousands. Pull builder plans, your survey, or any prior appraisal to prove the actual number.
5. File on iFile
Go to hcad.org/hcad-online-services/ifile-protest. Log in with your iFile number (also on the notice) and account number. Click "File a Protest." Select reason: "Value over market" and "Value unequal compared with other properties." Both. Always.
Upload the comps, photos, and any other evidence. Hit submit. You should get a confirmation email immediately and a hearing date or iSettle offer within a few weeks.
6. Take the iSettle Offer or Go to Hearing
HCAD often comes back with an iSettle offer (a number they will accept without a hearing). If it cuts your value by what you wanted, take it and be done. If it does not, request the formal Appraisal Review Board hearing. Bring your evidence pack. The ARB members are reasonable, and a clean evidence pack of three to five comps and condition photos almost always moves the number.
Fort Bend, Montgomery, Brazoria, and Galveston
The process is identical. Each county runs its own appraisal district with its own iFile portal.
- Fort Bend (FBCAD): fbcad.org. iFile is on the homepage. Same May 15 deadline.
- Montgomery (MCAD): mcad-tx.org. Online protest tool linked from the homepage. Same deadline.
- Brazoria: brazoriacad.org.
- Galveston: galvestoncad.org.
Common Mistakes That Tank Your Protest
- Arguing taxes are too high. They might be, but that is a legislative issue. The ARB cannot lower your tax rate. Argue the value, not the tax.
- Submitting comps that closed above your appraisal. Pull three good ones, not eight mediocre ones. The mediocre ones get used against you.
- Including comps from outside your subdivision or zip code. The appraisal district is going to throw out comps that are not "comparable enough." Stay tight on geography.
- Comps from more than 12 months ago. Six months is the gold standard. Twelve is the absolute outer limit.
- Filing right at the deadline. File the day you get your notice. Earlier filings get earlier hearing dates and the ARB has more flexibility before its calendar fills up.
- Skipping the hearing if iSettle is low. If HCAD's iSettle offer cuts your value by 3 percent and you wanted 10, don't sign. Go to hearing. The ARB averages bigger cuts than iSettle offers.
Should You Hire a Tax Protest Service?
Services like ProTax, O'Connor, and Five Stone charge a percentage of your tax savings (typically 30 to 50 percent of year-one savings). They will protest for you, attend the hearing, and submit evidence. They are worth it if you do not have the time, do not want to do the homework, or own a higher-end home where the dollar swings are larger.
For an average Houston homeowner with a $300K to $600K home, doing it yourself and keeping 100 percent of the savings is usually the better play. The 15 minute time investment beats giving up half the money.
What If You Just Bought the Home?
You can still protest. In fact, you should. If you bought in the last 12 months for less than HCAD's appraised value, that purchase price is your strongest evidence. Submit your closing disclosure (HUD-1 in older deals) along with one or two comps. The ARB almost always takes a recent arm's length purchase as the new market value.
If you closed with us at InSync, reply to this article or email Ben at ben@insync.homes and I will pull the comp pack for your address from the same MLS data we use to write offers. It is the same evidence I use on my own home each year.
The Bottom Line
Property tax protests are the highest-ROI 15 minutes a Houston homeowner can spend each year. The deadline is May 15, the process is free, the worst case is HCAD says no, and the typical case is $700 to $1,000 back per year on a $400K home. File on iFile, attach three to five recent comps and a few condition photos, and either accept iSettle or take it to the ARB hearing.
And yes, file it again next year, and the year after. The 10 percent homestead cap means each successful protest compounds. This is the closest thing to free money the Texas tax code gives you. Use it.
