Property tax protest for Houston owners
The Houston property tax protest walkthrough.
HCAD, FBCAD, MCAD, and Brazoria CAD mail out appraisal notices in April every year. The deadline to protest is May 15 or 30 days from the notice date, whichever is later. Owners who protest with evidence usually win a reduction. Owners who don’t accept whatever the appraisal district set.

What the notice means
The appraisal district sets the value. You can challenge it.
Every Greater Houston county has its own appraisal district: HCAD for Harris County, FBCAD for Fort Bend County, MCAD for Montgomery County, and the Brazoria County Appraisal District. Each one mails a Notice of Appraised Value to property owners in April, showing the value the district has set for the property as of January 1 of that year. That value drives the property tax bill the following October.
The notice usually includes two numbers: the appraised (market) value and the assessed value. The assessed value is the number actually used to calculate taxes — and for homestead-exempt properties, the assessed value cannot increase more than 10% per year regardless of how high the appraised market value goes. That cap is one of the most valuable benefits of the homestead exemption in Texas.
The action window is short. The deadline to file a protest is May 15 or 30 days from the date the notice was mailed, whichever is later. Miss the deadline and the appraisal becomes final for the year — no appeals, no second chances. Calendar the deadline as soon as the notice arrives.
The three protest grounds
File on at least one. File on all three when applicable.
Market value too high
The district’s appraised value exceeds what the property would actually sell for on January 1. Evidence: recent sale of the subject property, comparable sales of similar homes nearby that sold for less, recent appraisal from a refinance or purchase, documentation of condition issues (foundation, deferred maintenance, flood damage history) that reduce market value.
Unequal appraisal
The property is appraised higher than other similar properties in the same neighborhood. Evidence: a list of comparable nearby properties with their appraised values from the district’s own records, showing that the subject is being valued out of line with similar homes. This ground often wins even when market value is technically defensible.
Exemption denied or wrong
The district failed to apply a homestead exemption, over-65 exemption, disability exemption, or veteran exemption that the owner is entitled to. Evidence: documentation of eligibility (ID showing the address, proof of age, VA disability rating, etc.) plus the original exemption application if the issue is administrative.
The walkthrough
Six steps from notice to resolution.
Read the notice carefully
Note the appraised value, the assessed value, the date the notice was mailed, the protest deadline, and whether any exemptions are reflected on the notice. If a homestead exemption is missing, that’s a separate fix that usually doesn’t even require a protest — just an exemption application.
Pull the evidence package
Comparable sales of similar nearby homes that closed for less than the district’s appraised value (a Houston REALTOR® can pull these from the MLS). The district’s own data on appraised values for similar properties in the neighborhood (the unequal-appraisal evidence). Documentation of any condition issues with photos, repair estimates, or inspection reports.
File the protest online
Each county appraisal district has an online portal. HCAD uses iFile, FBCAD uses an online protest system, MCAD has an online process, Brazoria CAD has an online portal. Select the protest grounds, attach evidence, and submit before midnight on the deadline date. Confirmation emails should arrive immediately — save them.
Informal hearing with an appraiser
Before the formal hearing, the district usually offers an informal phone or in-person conversation with one of their appraisers. Present the evidence calmly, respond to questions about the property, and listen for a settlement offer. Many Houston protests resolve at this stage with a meaningful reduction.
Formal hearing with the Appraisal Review Board
If the informal settlement is unacceptable, the protest moves to the Appraisal Review Board (ARB) — a panel of citizens that hears the case formally. Present the evidence, allow the district’s appraiser to present theirs, and the panel rules. The hearing is usually 15–30 minutes.
Appeal options if the ARB ruling disappoints
Three appeal paths: binding arbitration (limited to properties at certain value tiers), State Office of Administrative Hearings (more complex, less commonly used), or district court litigation (highest cost, highest stakes). Most owners stop at the ARB unless the protest is over a substantial valuation difference.
The 10% homestead cap math
Why protests still matter even when the cap is in effect.
A homestead-exempt Texas property has its assessed value capped at 10% increase per year. If the appraised market value jumps 25%, the assessed value (the one actually used for taxes) only goes up 10%. That sounds like the protest is unnecessary — the cap is doing the work. It isn’t.
The appraised market value still matters in two ways. First, when the homeowner sells or removes the homestead exemption, the assessed value resets to the appraised value — meaning a chronically inflated appraisal becomes the next owner’s problem (or the seller’s, on the year of sale). Second, the assessed value continues climbing 10% every year until it catches the appraised value — an unchallenged inflated appraisal locks in years of higher future taxes. Protesting the appraised value protects the long-term tax position even when the current-year cap is active.
DIY vs. property tax consultant
Self-file, hire a firm, or have your REALTOR® help with comps.
Self-file
Best for owners who are comfortable pulling comparable sales, organizing evidence, and presenting a case. Cost: zero. Time: typically 3–5 hours of preparation plus the hearing. Best results come from a tight evidence package with clear comp data.
Property tax consultant
Houston has many firms that file protests for a contingency fee — typically 25–40% of the first-year tax savings. Best for owners who don’t want to handle the process, or owners with multiple properties where the time cost of self-filing adds up. Consultants are most effective on commercial and high-value residential properties.
Comp pull from a REALTOR®
A middle path: the owner files the protest themselves, but a REALTOR® pulls the MLS comp evidence package. The REALTOR® has access to closed-sales data that owners can’t pull directly from public records. Eddie helps Houston clients with this every year — no consultant fee, just a clean evidence package.
Property tax FAQs
Common questions about the Houston protest process.
What if I miss the May 15 deadline?
For most properties, missing the deadline means the appraisal becomes final for the year and the owner pays based on it. Limited late-filing exceptions exist for owners who didn’t receive the notice, owners with substantial errors in the appraisal, and a few other circumstances. The safe approach: file the protest as soon as the notice arrives, before May 15 even seems close.
Will protesting raise my taxes?
No. The protest can only reduce or leave the appraised value unchanged — the appraisal district cannot increase the value as a response to a protest. The worst-case outcome of a protest is the original value, which is the value the owner would have paid anyway by not protesting.
How much should I expect to save?
Highly variable by property and by year. A well-prepared protest on an overvalued home can reduce the appraisal 5–15%, which at the typical Greater Houston combined tax rate of around 2.0–2.5% translates to several hundred to a few thousand dollars per year. The savings compound — a $500 annual reduction over a 10-year hold is $5,000 of preserved cash flow.
What if I just bought the home recently?
A recent purchase is some of the strongest evidence available — the closing statement directly shows what a willing buyer paid a willing seller, which is the textbook definition of market value. If the appraised value exceeds the recent purchase price, the protest is usually straightforward.
Should investment properties also be protested?
Yes — arguably more aggressively than primary residences, because investment properties don’t carry the 10% homestead cap. Inflated appraisals on rentals translate directly to higher annual tax bills with no cap protection. Every property in a portfolio should be reviewed against the prior year’s appraisal, and a protest filed any year the increase exceeds neighborhood comp trends.
How does the homestead exemption interact with the protest?
The homestead exemption is filed once (a separate process from the protest) and applies year after year as long as the property remains the owner’s primary residence. The annual protest is about the appraised value, not the exemption itself. Some homeowners forget to file for the homestead in the first place — if the notice shows no homestead exemption and one should apply, file the exemption application alongside the protest.
