Harris County Property Tax Exemptions and Protests

Two Offices, Two Different Jobs

Many homeowners lose time because they call the wrong office first. In Harris County, the appraisal district and the tax office do different work.

HCAD appraises property, keeps appraisal records, reviews exemption applications, and handles protests before the Appraisal Review Board, or ARB. HCAD does not set tax rates.

The Harris County Tax Office receives certified values from HCAD, applies tax rates set by local taxing units, sends tax statements, accepts payments, and handles delinquent collection work for the units it collects for.

Check Your HCAD Record Before You File Anything

Look up your property on the HCAD site. Check the account number, owner name, mailing address, property address, land size, building area, class, year built, exemptions, and taxing jurisdictions.

If you received a value notice, compare it to the online record. Your notice should show the value HCAD placed on the property and, when applicable, the protest deadline.

A high tax bill can come from several things. It may be a higher appraised value. It may be a missing exemption. It may be a tax rate set by a school district, city, county, MUD, or other taxing unit. It may also include penalty, interest, or collection charges if the bill is late.

A protest can address value, unequal appraisal, exemptions, and certain appraisal issues. It is not a protest against the tax rate itself.

Exemptions Are Different From Protests

An exemption removes part of your home value from taxation, or in limited cases all of it. A protest challenges an appraisal district action for a tax year, such as the appraised value or a denied exemption.

You may need one, the other, or both. If your homestead exemption is missing and your value also seems too high, apply for the exemption and protect your protest rights before the protest deadline.

Common Harris County Homestead Exemptions

HCAD’s homeowner exemption page explains the main residence homestead exemptions used in Harris County.

For school district taxes, Texas currently requires a general residence homestead exemption of at least $140,000 for qualified homeowners. HCAD also says Harris County currently provides a 20% optional homestead exemption for county taxes. Other local taxing units may offer their own optional exemptions, and those choices vary.

Texas also has added school-tax exemptions for homeowners who are age 65 or older or disabled. HCAD says qualified over-65 and disabled homeowners receive an additional $60,000 school-tax exemption. Some local taxing units may offer more local relief, but not all do.

Disabled veteran and surviving spouse rules are separate. A 100% disabled veteran residence homestead exemption is not for every veteran. HCAD states that the veteran must have a 100% disability rating or individual unemployability from the U.S. Department of Veterans Affairs, receive 100% disability payments from the VA, and have a service-connected disability. Other disabled veteran exemptions may use different forms and rules.

Forms and documents

HCAD lists the current forms on its forms page. The residential homestead form is listed as Form 11.13 for general residential, over-65, disability, over-55 surviving spouse, and 100% disabled veteran homestead applications.

Documents depend on the exemption. Common items include:

• HCAD account number, if known;
• property address and mailing address;
• proof that you own and occupy the home as your principal residence;
• Texas driver’s license or Texas ID information when required;
• recorded deed, closing statement, probate record, or other title proof if ownership is unclear;
• disability, physician, Social Security, or VA documents when relevant; and
• death certificate, marriage proof, or surviving spouse documents when relevant.

Exemption Deadlines and Late Filing Cautions

HCAD says regular residential homestead exemption applications should be filed between January 1 and April 30. If the application is postmarked by April 30, HCAD has time to process it before tax statements go out in the fall.

If you miss that date, do not assume you are out of options. HCAD says a general exemption can still be filed up to two years after the date taxes became delinquent for the year, which is usually February 1 of the following year.

Over-65 and disability timing can be different when you turn 65, become disabled, or acquire and occupy a new home during the year. HCAD says the deadline for the year you qualify is generally the first anniversary of the date you qualify.

Late rules are easy to misunderstand. If you missed a deadline, ask HCAD which tax year can still be corrected and whether a protest or correction motion is also needed.

When a Protest May Be the Right Path

A protest is often the right path when you disagree with HCAD’s market value, think similar properties are appraised lower, believe your exemption was wrongly denied or cancelled, or think HCAD used a value-related fact that is wrong.

The Texas Comptroller protest guide says taxpayers may discuss objections about property value, exemptions, special appraisal qualification, and the circuit breaker limitation at the ARB.

A protest is not mainly about hardship. The ARB looks at facts and evidence. It does not set tax rates. It does not decide whether the bill is affordable.

The main protest deadline

For Harris County property in 2026, HCAD’s protest deadline reminder said property owners who disagreed with the opinion of market value had until May 15, 2026, or 30 days after the date on their property value notice, whichever was later.

HCAD also said owners who received notices after April 15, or had not received a notice yet, should still have 30 days to file. The later deadline should be printed on the value notice. Check your HCAD account if the notice was not delivered.

For later years, do not rely on a remembered date. Check the current HCAD notice and the current HCAD protest page.

How to file a protest with HCAD

HCAD offers electronic filing through its owner system. The iFile and iSettle page says the value notice includes the account number and unique iFile number in the upper right corner. HCAD says you need those numbers to file online unless the property is already linked to an existing owners account.

You can also use the official Notice of Protest form. HCAD lists the Notice of Protest as Form 50-132 on its forms page.

If mailing close to the deadline, HCAD warned owners to have the envelope manually stamped at the post office because the postmark may reflect processing by a sorting machine, not the time the mail was dropped in a box.

Evidence That Helps in a Harris County Protest

Evidence should answer one question: what fact is wrong, and how can you prove it?

Do not build your case only around the statement, “My taxes are too high.” That may be true, but the ARB is looking at appraisal facts.

• photos of needed repairs, damage, flooding, foundation issues, roof problems, or unfinished work;
• contractor estimates, repair invoices, inspection reports, or engineering reports;
• a closing statement if you bought the property close to January 1;
• recent comparable sales, with addresses, dates, condition, square footage, and photos if possible;
• proof that HCAD has the wrong square footage, land size, features, or condition;
• exemption approval letters or application proof if the dispute is about a missing exemption; and
• a short written summary of the value or correction you are asking for.

HCAD’s protest process document says an informal meeting may be scheduled first. The purpose is to review the protest with an HCAD appraiser and see if the issue can be resolved without a formal ARB hearing.

HCAD’s 2026 deadline reminder also says homeowners who file electronically and opt in to iSettle may be able to upload evidence through the owners website. It said owners would have five days from the date they filed electronically to submit documentation such as a closing statement, deed, or photos for iSettle review.

What Happens at the ARB

The Appraisal Review Board is separate from appraisal district staff. It hears protest cases and correction matters within the limits of Texas law.

The Texas Comptroller says the ARB must send notice of the hearing date, time, place, subject matter, and information about accessing estimated taxes at least 15 days before the hearing.

At the formal hearing, both you and the appraisal district can present evidence. HCAD’s protest process document says ARB formal hearings are conducted by three-member panels and are recorded. It also says individual owners who appear in person must check in at least 15 minutes before the scheduled hearing time.

Bring copies or upload evidence as instructed in your hearing notice. HCAD’s protest process document says a person appearing in person must provide four copies of documents intended for the hearing, or use the allowed electronic process. It also says the ARB will not accept evidence by email.

Read your scheduling notice carefully. Remote, telephone, written affidavit, and in-person hearings can have different check-in and evidence rules.

If the Property Record Is Wrong

Some problems are not just value disagreements. The record itself may be wrong. Examples include wrong owner name, wrong mailing address, wrong legal description, wrong building size, duplicate account, an improvement listed that did not exist on January 1, or property assigned to the wrong taxing jurisdiction.

HCAD’s forms page lists correction forms, including a request to correct name or address on a real property account and real property correction request forms. The Harris County Tax Office also says legal description problems and homestead assigned to the wrong lot must be directed to HCAD.

Some correction issues are narrow. HCAD’s correction process document says Texas law allows correction of only certain errors in the appraisal roll and only under limited circumstances. It also says a motion should explain the issue in detail and include proper documentation, or the motion will likely be denied.

Do not assume a correction motion replaces a timely protest. Most valuation errors must be handled during the protest period. Late correction rights are limited.

If You Are Late

If the protest deadline passed, act quickly anyway. The Texas Comptroller says the usual protest deadline is May 15 or 30 days after the notice was mailed, whichever is later. The ARB may grant a late protest hearing if the owner can show good cause, but filing too late can mean losing the right to protest.

There are also limited late procedures for failure to receive a required notice, substantial over-appraisal, clerical error, multiple appraisal, property that should not have been included, ownership error, and agreed joint motions. These rules are technical. They can also require payment of taxes not in dispute before delinquency.

Late protest and correction rules are not general second chances. Call HCAD, read the official correction information, and consider legal help if the amount is large or foreclosure risk is involved.

If Your Exemption Is Denied or Removed

If HCAD denies or removes an exemption, read the notice closely. Look for the reason, the tax year, and any protest or appeal deadline.

Then gather proof that matches the missing requirement. For a homestead, that may mean proof of ownership and occupancy. For over-65, disability, veteran, or surviving spouse exemptions, it may mean age, disability, VA, marriage, death, ownership, occupancy, or remarriage documents.

If the denial involves heir property, probate, or family ownership, the issue may be partly a title problem. HCAD cannot give legal advice. A legal-aid office or property lawyer may be needed when ownership is unclear.

Deferrals Are Not the Same as Exemptions

Some over-65 or disabled homeowners ask about delaying property tax collection. HCAD’s tax deferral page says Texas law permits a homeowner who is 65 or older or disabled to defer payment of current property taxes on the person’s residence homestead until the person no longer owns or occupies the home as a residence.

This is serious. HCAD says property taxes continue to accrue during the deferral period and are assessed interest at 5% per year. HCAD also says a deferral postpones payment; it does not eliminate the taxes.

When the deferral ends, taxes and accrued amounts must eventually be paid. HCAD warns that homeowners with mortgages should check whether a deferral could violate mortgage or deed-of-trust terms.

A Simple Action Plan

1. Find your HCAD account. Check the online record and value notice.
2. Write down the exact problem. Is it value, exemption, ownership, address, square footage, legal description, or tax payment?
3. Check the deadline. For protests, use the deadline on the notice or HCAD account.
4. File before the deadline if value or exemption is disputed. Do not wait for every document if the deadline is close.
5. Gather proof. Photos, repair estimates, sales records, closing statements, exemption documents, and title records matter.
6. Follow HCAD evidence instructions. Use the owner portal, iSettle, hearing notice, or ARB rules.
7. Keep copies. Save confirmations, postmarked envelopes, emails, uploaded documents, and hearing notices.
