How to protest property taxes in Houston and Harris County
To protest property taxes in Harris County, an owner must file a written notice of protest with the appraisal review board by the deadline (Tax Code 41.44(a)) to be entitled to a hearing and determination, except as 41.44(b), (c), (c-1) and (c-2) provide. The Harris Central Appraisal District (HCAD) lists these ways to file: online, by mail, and in person at its office (HCAD FAQ).
This page describes what the Texas Tax Code, the Texas Comptroller and HCAD publish about filing a protest. It is not legal advice, and it does not say whether any filing route, including iSettle, applies to a particular property. The appraisal review board or the appraisal district decides each case.
What are the steps to protest property taxes in Harris County?
To be entitled to a hearing and determination, an owner must file a written notice of protest with the appraisal review board by the deadline, except as 41.44(b), (c), (c-1) and (c-2) provide (Tax Code 41.44(a)).
- The written notice goes to the appraisal review board by the deadline (Tax Code 41.44(a)), except as 41.44(b), (c), (c-1) and (c-2) provide. For a mailed protest, see the postmark rule.
- HCAD lists these ways to file: online, by mail, and in person at its office (HCAD FAQ).
- Form 50-132, which HCAD lists under Popular Forms (HCAD forms), says to select all boxes that apply.
- After a notice is filed, the board schedules a hearing (Tax Code 41.45(a)); see what happens after you file.
What is the notice of appraised value?
Tax Code 25.19(a) requires the chief appraiser to deliver a clear and understandable written notice of the appraised value of a property owner's property when one of four conditions is met:
- the appraised value is greater than it was in the preceding year;
- the appraised value is greater than the value the owner rendered;
- the property was not on the appraisal roll in the preceding year; or
- an exemption or partial exemption approved for the preceding year was canceled or reduced for the current year.
What are the ways to file a property tax protest in Texas?
HCAD's FAQ lists three ways to file in Harris County: online, by mail, and in person at its office. A notice of protest need not be on an official form (Tax Code 41.44(d)), and it is sufficient if it identifies the protesting property owner, identifies the property, and indicates apparent dissatisfaction with some determination of the appraisal office.
The filing instructions on Form 50-132 say to file it with the appraisal district office in the county in which the property is taxable, not with the Comptroller. The table gives what HCAD's FAQ says about each way to file:
| Way to file | What HCAD says |
|---|---|
| Online (iFile) | Through an owner's account in HCAD's Electronic Filing and Notice System, or with the iFile number printed on the notice. |
| By mail | A paper protest by mail. The postmark rule is below. |
| In person | At HCAD's office, 8 a.m. to 5 p.m. HCAD says it has no drop box for use after normal business hours. |
What do you need to file on HCAD iFile?
HCAD's iFile page says the property account number and the unique iFile number are both displayed in the upper right corner of the notice of appraised value, and that an owner needs both numbers to file a protest online. HCAD's May 6, 2026 release says the iFile system cannot be used to file a protest without the iFile number unless the owner has an existing electronic owners account linked to the property, and that an owner using the protest form does not need an iFile number.
The iFile page says to enter the property account number on HCAD's website and select File a Protest, which opens the Electronic Filing and Notice System at owners.hcad.org.
An owner who has misplaced the notice can use the HCAD mobile app to retrieve the iFile number with a driver's license, but HCAD's FAQ says the license must have the same address as the address on the account.
What is HCAD iSettle?
HCAD's owners help page says iSettle is the term for having a protest considered for an electronic value reduction offer, and that submitting a protest through iFile does not automatically opt it in.
HCAD's iFile page says it is important for an owner who wants to be considered to check the iSettle option on the protest. HCAD's help page lists these conditions for participating:
- The property must be listed as single-family residential.
- The owner must iFile with a valid email address and give an opinion of value.
- A very small number of income-valued neighborhoods are excluded.
An appraiser reviews the data, and HCAD notifies the owner by email of a decision that the owner can accept or reject (iFile page).
When is the deadline to protest property taxes in Harris County?
Except as 41.44(b), (c), (c-1) and (c-2) provide, Tax Code 41.44(a)(1) sets the deadline at "not later than May 15 or the 30th day after the date that notice to the property owner was delivered to the property owner as provided by Section 25.19, whichever is later". HCAD's FAQ counts the 30 days from the date the notice of appraised value was mailed, and says that when May 15 falls on a weekend or holiday the deadline is the next business day. The 2026 deadline has passed.
The protest deadline guide covers the deadline in full, and the missed-the-deadline guide covers late filing.
How does a mailed protest count as on time?
HCAD's FAQ says a mailed protest must be postmarked by the U.S. Postal Service on or before the protest deadline, or sent in a way that lets the owner keep a receipt as proof it was mailed on or before the deadline. Separately, Tax Code 1.08 says that when a property owner is required by this title to make a payment or to file or deliver a report, application, statement, or other document or paper by a specified due date, "the property owner's action is timely if it is properly addressed with postage or handling charges prepaid and:"
- "it is sent by regular first-class mail and bears a post office cancellation mark of a date earlier than or on the specified due date and within the specified period;"
- "it is sent by common or contract carrier and bears a receipt mark indicating a date earlier than or on the specified due date and within the specified period; or"
- "it is sent by regular first-class mail or common or contract carrier and the property owner furnishes satisfactory proof that it was deposited in the mail or with the common or contract carrier on or before the specified due date and within the specified period."
What happens after you file a protest?
On the filing of a notice as required by Section 41.44, the appraisal review board schedules a hearing as soon as practicable, but not later than the 90th day after the date the board approves the appraisal records (Tax Code 41.45(a)).
The appraisal office holds an informal conference before the hearing with an owner who files a notice of protest and requests one (Tax Code 41.445). HCAD's protest process insert says an owner whose protest is not resolved informally is sent a second scheduling notice for a formal hearing. The protest hearing guide covers the informal conference, the notice and the hearing.
How does an owner appoint an agent instead?
An owner appoints an agent by written authorization on a form the Comptroller prescribes, Form 50-162, Appointment of Agent for Property Tax Matters (Tax Code 1.111(b)). The designation does not take effect with respect to an appraisal district or a taxing unit participating in the district until a copy is filed with the appraisal district (1.111(b)).
Does an owner have to appoint an agent to protest?
Tax Code 1.111(g) bars an appraisal district, appraisal review board or taxing unit from requiring a person to designate an agent to represent the person in a property tax matter other than as provided by Section 1.111, and Tax Code 41.66(c) lets an owner who is entitled to appear at a hearing appear by himself or by his agent. The guide on whether you need a company covers the question, and the fee comparison shows what Houston companies charge.

Questions
Does it cost anything to file a protest?
Tax Code 41.41(d) says an appraisal district or the appraisal review board may not require a property owner to pay a fee in connection with a protest filed by the owner with the board. The should I protest guide covers the fee rules.
Does an owner have to appear in person?
Tax Code 41.45(b) says a property owner initiating a protest may appear in person, may offer evidence or argument by affidavit without personally appearing, and may appear by telephone conference call or videoconference to offer argument, in which case any evidence must be offered by affidavit. An affidavit must be submitted to the board hearing the protest before the board begins the hearing. The protest hearing guide covers each way to appear.
Can an owner ask for a single-member panel?
Tax Code 41.45(b-4) says the board shall sit in a single-member panel if the owner requests it in the notice of protest, or in writing submitted not later than the 10th day before the hearing.
What if the iFile option is disabled?
HCAD's help page says the option is typically disabled when a protest has already been filed for the property, and is also disabled when a property has to be re-noticed. It adds that once the new notice is created, the option will be available.
