Harris County tax assessor-collector: everything homeowners need to know

Last updated 2026-07-09

What does the Harris County Tax Assessor-Collector actually do?

The Tax Assessor-Collector collects your taxes. It does not decide what your home is worth. Mixing those two up costs homeowners their protest window every single year.

The Harris County Tax Assessor-Collector is an elected official who collects property taxes, issues vehicle registrations and titles, and keeps voter registration records ^[1]. The current officeholder is Ann Harris Bennett, in the seat since 2017 ^[1]. Her office builds your bill by taking the appraised value set by HCAD, subtracting any exemptions you qualify for, and multiplying by the tax rates that Harris County, the City of Houston, Houston ISD, and dozens of other jurisdictions adopt each fall.

So if a notice landed in your mailbox and scared you, stop and check which piece of paper you are actually holding. An appraisal notice (Form 25.19) comes from HCAD, usually in April, and shows your proposed market and assessed value. A tax bill comes from Ann Harris Bennett's office, usually in October, and shows the dollars you owe. Two documents. Two deadlines. Two completely separate ways to push back.

Confusing them is the number one reason people miss their chance to protest.

Who sets property values in Harris County, and how does that affect your bill?

The Harris Central Appraisal District (HCAD) sets values, not the Tax Assessor-Collector. HCAD appraises all taxable property in Harris County as of January 1 each year ^[2]. The chief appraiser has to value property at market value under Texas Tax Code Section 23.01, defined as "the price at which a property would transfer for cash or its equivalent under prevailing market conditions" ^[3].

HCAD mails notices of appraised value, usually in April. If your value climbed, that notice is your starting gun. You have until May 15 or 30 days after the notice date, whichever is later, to file a protest ^[4]. Miss it and you lose the right to challenge that year's value, with narrow exceptions.

Once protests wrap up and exemptions are applied, HCAD certifies the appraisal roll to the Tax Assessor-Collector, usually in July or August. Each taxing unit then sets its rate in the fall. Ann Harris Bennett's office multiplies your certified taxable value by those rates and mails the bill ^[1].

The takeaway is simple. Lowering your tax bill means lowering your appraised value at HCAD. Calling the Tax Assessor-Collector to argue about your value is a normal instinct, and it will get you nowhere.

What are the key deadlines for Harris County property taxes?

Texas property tax dates do not bend. Here is the full cycle to track:

Event	Typical Date	Authority
HCAD appraises property as of	January 1	Tex. Tax Code §23.01 [3]
HCAD mails appraisal notices	April (varies)	Tex. Tax Code §25.19 [4]
Protest deadline (standard)	May 15 or 30 days after notice, whichever is later	Tex. Tax Code §41.44 [4]
Taxing units adopt rates	September-October	Tex. Tax Code §26.05
Tax bills mailed by Tax Assessor-Collector	October-November	Tex. Tax Code §31.01 [1]
Last day to pay without penalty	January 31	Tex. Tax Code §31.02 [5]
Penalty begins	February 1 (7% added)	Tex. Tax Code §33.01 [5]
Additional penalty	July 1 (additional 15-20% collection fee possible)	Tex. Tax Code §33.07 [5]

The May 15 deadline matters most. If HCAD mails your notice late (say April 20), your deadline slides to May 20, not May 15. Count from your notice date, always. HCAD's online portal lets you file electronically, and that timestamp is what counts ^[2].

Payment has some flexibility for a few groups. Homeowners with the over-65 or disability homestead exemption can pay in installments without penalty under Texas Tax Code Section 31.031 ^[5]. Everyone else owes the full amount by January 31.

Got an escrow account? Your mortgage servicer is supposed to pay by January 31 out of your impound account. Verify that it did. Servicer errors happen, and the penalty and interest land on you, not your lender.

How do you read a Harris County tax bill?

Your bill lists a separate line for every taxing unit with authority over your property, each with its rate and dollar charge. For a typical Houston homeowner inside HISD, that list usually runs seven lines deep: Harris County, Harris County Flood Control District, Port of Houston Authority, Harris County Hospital District (Harris Health), Harris County Department of Education, City of Houston, and Houston Independent School District.

Each line shows that entity's rate in dollars per $100 of taxable value and the dollar amount charged. Your taxable value is your HCAD appraised value minus exemptions.

Here is the math with round numbers. HCAD values your home at $350,000. A standard homestead exemption removes $100,000 from the school district portion, so your taxable value for HISD is $250,000. At a hypothetical HISD rate of $1.0924 per $100, that slice of your bill is about $2,731. Add county, city, and the special districts and you land on your total.

Look up your account, confirm your exemptions, and pull past bills at harriscountytax.com ^[1]. Your account number sits on the bill and ties your records together across both HCAD and the tax office.

What exemptions can reduce your Harris County property tax bill?

Exemptions are where homeowners leave the most money sitting on the table. Texas law and the state constitution authorize several, and HCAD administers most of them even though the savings show up on your tax bill ^[2].

The common ones:

Homestead exemption. If the home is your principal residence, you get a $100,000 cut in taxable value for school district taxes under Texas Tax Code Section 11.13(b), as amended by Senate Bill 2 (2023) ^[6]. School districts have to apply it. Filing also caps how much your assessed value can rise year over year for school taxes ^[6].

Over-65 exemption. Homeowners 65 or older get an extra $10,000 school district exemption plus a freeze on the dollar amount of their school taxes for as long as they live there ^[3].

Disability exemption. Qualify for disability under Social Security standards and you get the same freeze benefit as the over-65 exemption ^[3].

Disabled veteran exemptions. These run from a $5,000 reduction (10-29% disability rating) up to a full 100% exemption for veterans rated 100% disabled or unemployable by the VA ^[3].

Surviving spouse exemptions. Surviving spouses of first responders killed in the line of duty may qualify for a 100% exemption ^[3].

To apply, file Form 50-114 (Residence Homestead Exemption Application) with HCAD, not the Tax Assessor-Collector. You can do it online at hcad.org ^[2]. No fee. Once approved, the homestead exemption renews on its own as long as HCAD sees no sign you moved.

Bought and moved in after January 1? You can still get a prorated exemption for the part of the year you owned and lived there, thanks to a 2022 constitutional amendment.

How do you protest your Harris County appraisal (without hiring a contingency firm)?

You can run your own protest, and every dollar you save stays yours instead of handing 25 to 40 percent to a contingency firm. Three stages: informal review, Appraisal Review Board (ARB) hearing, and if it comes to it, judicial appeal or arbitration.

Stage 1: Informal review. File your protest online at hcad.org and HCAD usually offers an informal conference with an appraiser before the formal ARB hearing ^[2]. This is your fastest path to a win. Bring comparable sales (comps) of similar homes that sold for less than HCAD's value. Pull your neighborhood sales data straight from HCAD's site. If the appraiser agrees your value is too high, they can settle on the spot and you skip the ARB entirely.

Stage 2: ARB hearing. If informal review goes nowhere, your case moves to the Appraisal Review Board, an independent panel that is not made up of HCAD employees. They hear your evidence and HCAD's, then decide. Texas Tax Code Section 41.66 governs their procedures ^[4]. You have the right to see HCAD's evidence at least 14 days before your hearing. Ask for it. Their own numbers sometimes make your case better than anything you dig up yourself.

Strong evidence at the hearing: recent comparable sales of similar homes, a recent independent appraisal, photos of condition problems HCAD never saw, and the equity argument (your property is assessed higher per square foot than similar neighbors). Texas Tax Code Section 41.43 puts the burden on the appraisal district to establish value when you protest on market value grounds ^[4].

Stage 3: Post-ARB options. If the ARB rules against you and the tax in dispute is $50,000 or less, you can file for binding arbitration for $450 to $1,550 depending on property value, instead of going to district court ^[7]. District court is an option too, but it means attorney fees and years of waiting.

Want to run your own protest with professional-grade comps and prep? The TaxFightBack DIY appeal kit walks through the whole thing with property-specific comp analysis you can hand straight to the ARB.

One timing note. The Harris County ARB calendar runs roughly May through August. HCAD schedules tens of thousands of cases, so expect six to eight weeks between filing and your hearing date.

How do you pay Harris County property taxes, and what payment options exist?

The Tax Assessor-Collector takes payment more ways than most county offices. Pay online at harriscountytax.com by e-check (free) or credit/debit card (processor fee applies, usually around 2.2%) ^[1]. You can also pay by mail, in person at any branch office, or through a participating bank or credit union.

Harris County does not offer a general installment plan for regular homeowners. A few formal options do exist:

Installment plan for over-65/disabled homeowners. Under Texas Tax Code Section 31.031, qualified homeowners can pay in four equal installments due February 1, April 1, June 1, and August 1 without penalty ^[5].

Partial payment agreement. Texas Tax Code Section 31.07 lets an owner make partial payments, but interest keeps accruing on whatever is unpaid ^[5].

Delinquent installment agreement. Once taxes go delinquent, Section 33.02 lets the tax office set up a written repayment plan. It stops the collection process, though interest keeps running ^[5].

Own multiple properties? Each account has its own bill and its own deadline. A homestead exemption on one does not carry to another.

On escrow: the Tax Assessor-Collector mails bills to the address of record, which might be your servicer's address if they asked for it. Check your account status at harriscountytax.com each November to confirm the payment landed.

How does Harris County compare to other large counties on property tax rates?

Texas has no state income tax, so local taxing units lean hard on property taxes. Harris County's combined rates (county plus city plus school district plus special districts) have long ranked among the highest in Texas, though Senate Bill 2 (2023) and Proposition 4 (2023) forced real school district rate compression ^[6].

For the 2023 tax year, the Harris County Commissioners Court adopted a county rate of $0.3154 per $100 of assessed value ^[1]. The City of Houston's rate was $0.5336 per $100. HISD, after state compression under HB 3 (2019) and Proposition 4 (2023), ran around $1.0924 per $100. Total combined rates for a typical Houston homeowner inside HISD landed somewhere between $2.00 and $2.30 per $100 of taxable value, depending on which special districts applied.

Zoom out and Texas has some of the highest effective property tax rates in the country. The Lincoln Institute of Land Policy found Texas's effective tax rate on owner-occupied housing was about 1.60% in 2021, against a national median near 1.10% ^[8]. Harris County homeowners generally pay above the state average, thanks to Houston's higher home values and the stack of overlapping taxing districts.

To see how other big metro counties run assessments and appeals, the rules in Bexar County, Maricopa County, and Los Angeles County all differ in meaningful ways.

What if your Harris County taxes become delinquent?

February 1 starts the clock if you blew past January 31. Texas Tax Code Section 33.01 tacks on a 7% penalty right away, plus interest at 1% per month ^[5]. By July 1, if it is still unpaid, an added collection fee of up to 15-20% can hit the account once it goes to a delinquent tax attorney under Section 33.07 ^[5].

Harris County uses outside collection attorneys, as the statute allows. Their fee stacks on top of what you already owe. A delinquent account left alone from February through August can pile on 20-30% in penalties and fees above the original tax. On a $6,000 bill, that compounds fast.

For severe delinquency, the taxing units can sue to foreclose a tax lien. Texas does not allow a quick non-judicial foreclosure on a homestead for property tax debt, but judicial foreclosure is real and does happen, usually after several years of buildup.

Struggling to pay? Call Ann Harris Bennett's office early. They can confirm whether you qualify for an installment agreement under Section 33.02, and some hardship situations qualify for deferral under Section 33.06 (over-65 or disabled homeowners can defer taxes without penalty while they live there, though interest still runs at 5% per year) ^[5].

How do you contact or visit the Harris County Tax Assessor-Collector?

The main office is at 1001 Preston St., Houston, TX 77002. Ann Harris Bennett's office runs branch locations across the county, which helps given its size (more than 1,700 square miles). Branches serve Baytown, Humble, Katy, North Houston, and several other areas ^[1].

For property tax questions, the fastest routes are:

• Online account lookup and payment: harriscountytax.com ^[1]
• Phone: (713) 274-8000 (main line)
• Email contact forms live on the website by department

For appraisal protests or value questions, you need HCAD directly:

• Online protest and records: hcad.org ^[2]
• HCAD main office: 13013 Northwest Freeway, Houston, TX 77040
• Phone: (713) 812-5800

Two separate agencies, two separate addresses. Going to the Tax Assessor-Collector to protest your value is like calling your power company to argue about the rate your city council set. Right frustration, wrong building.

Need certified property records for a legal matter, survey, or lender? HCAD's public data portal at hcad.org has property cards, deed information, and sales history at no charge.

Can you get a tax deferral or hardship relief in Harris County?

Texas Tax Code Section 33.06 lets qualifying homeowners defer collection of property taxes on their homestead without the usual penalty and interest cascade, as long as they live there ^[5]. To qualify you must be 65 or older, disabled as defined by the Social Security Act, or the surviving spouse (at least 55) of someone who deferred.

The catch: interest still runs at 5% per year during the deferral, and the whole deferred amount (taxes plus interest) comes due when you sell or move out. Run a deferral 10 years on a $5,000 annual bill and you could owe $50,000 plus interest at closing. It buys time, not forgiveness.

If you do not qualify for statutory deferral but you are in genuine financial hardship, the remaining paths in Texas are the formal delinquent installment agreement (Section 33.02) or, in some cases, disaster-related relief under Section 11.35 if HCAD has declared an applicable disaster.

Texas has no general income-based circuit-breaker the way some other states do. The relief system here is almost entirely exemption-based (age, disability, veteran status), not income-based. Advocacy groups have flagged that gap for years, but as of 2024-2025, no income-based relief program exists at the state level.

What changed with Texas property tax law in 2023, and how does it affect Harris County homeowners?

2023 delivered the biggest structural change to Texas property taxes in decades. Senate Bill 2 (88th Legislature, 3rd Special Session) and Proposition 4 (approved by voters in November 2023) made several changes that hit Harris County bills directly ^[6].

The headline: the school district homestead exemption jumped from $40,000 to $100,000 of taxable value. On a $350,000 home, that pulls $60,000 more out of the taxable base for school taxes than the old rule did. At a compressed HISD rate near $1.09 per $100, that is roughly $654 in yearly savings from the exemption increase alone.

The law also forced school districts to compress rates further, paid for by extra state dollars flowing into local districts. The state comptroller's office projected the combined effect would cut the average Texas homeowner's property taxes by $1,300 or more a year, though actual savings swung widely by district and appraisal value ^[6].

HCAD confirmed the 2023 changes showed up in 2023 tax year bills. Homeowners without a homestead exemption on file missed the savings. If you have not filed Form 50-114 with HCAD, do it now. You can file for the current year any time before April 30 and have it apply to that year's taxes ^[2].

Senate Bill 2 also extended the appraisal cap (the 10% annual limit on assessed value increases) to all real property, beyond just homesteads, starting with the 2024 tax year. That is a separate change from the exemption amounts, and it reaches investment property owners and commercial landlords in Harris County too.

For homeowners in other high-growth Texas counties wondering how this plays out, the Bexar County tax assessor article covers San Antonio's version of the same changes.

Is it worth hiring a property tax protest firm, or should you do it yourself in Harris County?

Here is the straight answer. Harris County is one of the most protest-friendly counties in Texas. HCAD processes hundreds of thousands of protests a year, runs a functional online system, publishes accessible sales data, and offers an informal review that often settles cases before the ARB ever sees them. Give it two to three hours of prep and a motivated homeowner has a real shot at a reduction.

Contingency firms usually charge 25-40% of your first-year tax savings. On a $10,000 bill where they win you a $2,000 reduction, you hand over $500 to $800 for work you could have done. Every year, those fees compound.

The honest downside of doing it yourself: if your property is genuinely complex (acreage, income-producing, unusual construction), a specialist who knows HCAD's mass appraisal methodology and has MLS data you cannot see may pull a bigger reduction than you would alone. For a standard single-family home in a neighborhood with clean comps, the gap between DIY and a contingency firm shrinks to almost nothing.

To run your own protest with real comparable sales data and a step-by-step hearing prep guide, the TaxFightBack DIY appeal kit is built for Harris County homeowners who want to keep the full savings. It costs a flat fee, not a percentage.

For smaller Texas counties, or states with different rules entirely, check Bexar County, Maricopa County property tax, or San Diego property tax to see how those processes differ.

Frequently asked questions

What is the difference between the Harris County Tax Assessor-Collector and HCAD?

The Harris County Tax Assessor-Collector (currently Ann Harris Bennett) calculates and collects your tax bill. The Harris Central Appraisal District (HCAD) is a separate agency that sets your property's appraised value. To fight your value, you deal with HCAD. To pay your bill, set up an installment agreement, or get a receipt, you deal with the Tax Assessor-Collector.

When is the Harris County property tax protest deadline?

The standard deadline is May 15 or 30 days after HCAD mails your appraisal notice, whichever is later, under Texas Tax Code Section 41.44. If your notice arrived April 20, your deadline is May 20. You file with HCAD, not the Tax Assessor-Collector. Online filing at hcad.org time-stamps your submission and counts as a valid filing.

When are Harris County property taxes due?

Bills go out in October or November and are due January 31 under Texas Tax Code Section 31.02. A 7% penalty plus 1% monthly interest starts February 1. Over-65 and disabled homeowners who qualify can pay in four installments due February 1, April 1, June 1, and August 1 without penalty under Section 31.031.

How do I apply for a homestead exemption in Harris County?

File Form 50-114 (Residence Homestead Exemption Application) with HCAD, not the Tax Assessor-Collector. You can file online at hcad.org. No fee. You must own and occupy the home as your principal residence as of January 1. As of 2023, the school district homestead exemption removes $100,000 from your taxable value. Once filed, it renews automatically.

What happens if I miss the January 31 tax payment deadline in Harris County?

Texas Tax Code Section 33.01 adds a 7% penalty on February 1, plus 1% interest per month on the unpaid balance. By July 1, an added collection attorney fee of up to 20% can hit under Section 33.07. A delinquent $6,000 bill can grow past $7,500 by midsummer if ignored. Call the Tax Assessor-Collector early to ask about a delinquent installment agreement.

Can I defer Harris County property taxes if I am over 65?

Yes. Texas Tax Code Section 33.06 lets homeowners who are 65 or older, disabled, or qualifying surviving spouses defer collection of taxes on their homestead without penalty. Interest still runs at 5% per year. The full deferred amount plus interest comes due when you sell or move out. It is a cash-flow tool, not forgiveness.

How do I look up my Harris County property tax account?

Go to harriscountytax.com and search by property address, account number, or owner name. You can view your current bill, payment history, exemptions applied, and any delinquent balance. HCAD's separate portal at hcad.org shows your appraised value, comparable sales in your neighborhood, and your protest filing history.

What is the Harris County homestead exemption worth in dollars?

As of the 2023 tax year, the homestead exemption removes $100,000 of taxable value from your school district taxes under Proposition 4 (2023). At a compressed HISD rate near $1.09 per $100, that saves roughly $1,090 a year on school taxes alone versus no exemption. The exemption increase and rate compression together cut average Harris County school tax bills sharply from prior years.

Where are the Harris County Tax Assessor-Collector branch offices?

The main office is at 1001 Preston St., Houston, TX 77002. Branch offices serve Baytown, Humble, Katy, Cypress, North Houston, and other areas. Hours and addresses are listed at harriscountytax.com. For property tax questions, the online portal handles most transactions with no trip needed. For vehicle registration and title work, an in-person visit is often necessary.

What evidence should I bring to a Harris County ARB hearing?

Bring recent comparable sales of similar homes that sold below HCAD's appraised value, pulled from HCAD's public data or a real estate site with verifiable sales. Photos of condition problems HCAD may have missed also help. You can also run the equity argument under Texas Tax Code Section 41.43: if similar neighbors are assessed lower per square foot, that supports a reduction. Request HCAD's evidence package at least 14 days before your hearing.

Do disabled veterans get property tax relief in Harris County?

Yes. Texas Tax Code Section 11.22 provides exemptions from $5,000 up to 100% of value depending on VA disability rating. A veteran rated 100% disabled or with an unemployability designation gets a full homestead exemption, wiping out nearly all property taxes. Surviving spouses of veterans killed in action may also qualify for a 100% exemption. File with HCAD and include a copy of your VA disability letter.

How much do contingency protest firms typically charge in Harris County?

Most Houston-area contingency firms charge 25-40% of the first-year tax savings they get you. On a reduction that saves $2,000 in taxes, the firm keeps $500 to $800. If they file every year and your value keeps getting corrected, those fees pile up. For a standard single-family home with clear neighborhood comps, a DIY protest with the right data can match or beat a contingency firm's result.

Can I pay Harris County property taxes by credit card?

Yes. The Tax Assessor-Collector takes credit and debit cards online at harriscountytax.com and at branch offices. A third-party processor fee applies, usually around 2.2% of the transaction. E-check payments online are free. On a $5,000 bill the card surcharge runs about $110, so e-check saves that cost with no practical downside.

What did Proposition 4 (2023) do for Harris County homeowners?

Texas Proposition 4, approved by voters in November 2023, raised the school district homestead exemption from $40,000 to $100,000 and required school districts to compress their tax rates using added state funding. The Texas comptroller projected average savings of $1,300 or more a year. Harris County homeowners with a filed homestead exemption saw this reflected in their 2023 tax year bills.
