How to Protest Property Taxes in Harris County

Who does what in Harris County

The Harris Central Appraisal District (HCAD) determines appraised values. HCAD states that it does not assess or collect property taxes; questions about tax amounts, payments, or refunds go to the taxing jurisdictions. The Harris County Tax Office collects taxes. It is not the office that hears a value protest. A protest is heard by the Appraisal Review Board (ARB). HCAD's FAQ page states that a late protest may still be sent to the ARB with a statement of good cause, and the ARB decides whether the late protest is accepted.

The deadline: May 15 or 30 days after the notice was mailed

HCAD states the protest deadline as follows: the deadline is May 15, unless it falls on a weekend or holiday, in which case the deadline is the next business day. You can file until May 15, or 30 days after the date your notice of appraised value was mailed, whichever is later. If HCAD does not mail a required notice of appraised value on or before April 15, the protest deadline is 30 days after the date printed on the notice of appraised value.

Use the date on your own notice. Do not use a date from another property, another year, or a secondary summary. The notice date and the mailing date are the inputs to the rule, and the later of the two candidate dates controls.

April 30 is not a protest deadline

HCAD's homestead exemption page states that a regular residential homestead exemption application should be filed between January 1 and April 30, and that a late general exemption application can be filed up to two years after the date taxes became delinquent for the year. That April 30 date governs exemption applications. It does not govern protests. This guide does not state an April 30 early-protest deadline, because no HCAD protest page opened for this guide states one, and the protest FAQ states the May 15 rule without an April 30 fork. A claim that homestead owners must protest by April 30 was found only in secondary summaries and is not carried here.

How to file

HCAD states three filing routes: online, by mail, or in person at 13013 Northwest Freeway.

Online: file through your owner account using HCAD's Electronic Filing and Notice System. Once signed up, you can submit the protest electronically, have access to iSettle, and receive communications from HCAD electronically. Your iFile number is automatically linked to your account. The iFile number is printed in the upper right of the notice of appraised value. HCAD also states the iFile number can be retrieved through the HCAD mobile app using a driver's license, but the license must have the same address as the address on the account. If the account has not been noticed yet, no iFile number is available. The iFile number for a property other than a primary residence must be obtained through a public information request.

Paper: fill out Form 50-132, Property Appraisal - Notice of Protest, found under Forms, Popular Forms on the HCAD website. A paper protest may be filed by mail or dropped off at the HCAD office. A mailed protest must be postmarked by the U.S. Postal Service on or before the protest deadline for the account, or sent in a way that retains a receipt as proof it was mailed on or before the deadline. An in-person drop-off must happen during office hours of 8 a.m. to 5 p.m. HCAD states it does not have a drop box for protests left after normal business hours.

What happens after filing

HCAD states that an informal meeting with an appraiser and an ARB hearing both generally take 15 minutes or less, but filers should allow two hours between signing in and the actual start of the meeting or hearing. No evidence list, evidence deadline, or settlement-offer timeline is stated here, because no HCAD page opened for this guide states those details for iSettle beyond access through the owner account. If you missed the deadline, HCAD states you have missed the opportunity to protest for that year unless you can show good cause, by submitting a paper protest with a statement of good cause for the ARB to decide.
