Harris County homeowners face a median effective property tax rate of 1.49%, a median home value of $275,000, and a median annual bill of about $3,916. That combination is why a high Notice of Appraised Value from the Harris Central Appraisal District (HCAD) can hit your budget so hard.
Understanding your Harris County property tax bill starts with two jobs: reading how HCAD and local taxing units build the number, then lowering taxable value with exemptions and a timely protest. This guide walks through rates, your notice, bill math, exemptions, protest steps, and how to pay.
If you do not have a mortgage escrow account, you pay the county tax office directly by the due date rather than through your lender.
Key Takeaways
Harris County’s median effective tax rate is 1.49%, well above the U.S. median near 1.02% on Ownwell Trends data.
Your bill equals taxable value multiplied by the stacked rates of every taxing unit on the account (schools, city, county, flood control, and special districts).
The general residential homestead exemption cuts school taxable value by at least $140,000; apply through HCAD so the exemption and 10% homestead cap can attach.
The 2026 protest deadline was May 15, 2026 (or 30 days after HCAD mailed your notice). Plan for the 2027 cycle around the same mid-May date, or 30 days after your next notice is mailed.
2026 taxes are due January 31, 2027; look up and pay through MyHarrisCountyTax or the Harris County Tax Office (links in the resource table below).

How Do I Read My HCAD Notice of Appraised Value?
HCAD mails Notices of Appraised Value in the spring, often in April or early May (see HCAD’s property tax process guide). That timing is your window to protest. Tax bills for the year typically go out in the fall, with payment due the following January 31 (for the 2026 tax year, that is January 31, 2027).
Your notice covers these key components:
The market value is what HCAD believes your home would sell for in the current market.
The appraised value is HCAD’s certified value for taxation, generally set near market value before exemptions and the homestead cap.
The taxable value is the appraised value after exemptions and, for a qualified homestead, after the annual 10% cap limits how fast the value used for taxation can rise.
When comparing the market value to the assessed value, remember Texas homestead properties often show an appraised figure that still looks high while the value used for taxation is held down by the homestead cap, which limits annual increases to no more than 10%.
Taxable value is the number each taxing unit multiplies by its rate. A higher appraisal that sticks can raise what you owe to every unit on the bill at once.
Understanding Your Harris County Tax Bill
Your tax bill includes a lot of information, and some of it can be confusing. Here's a breakdown of the components using Harris County figures so you can see what you owe and why.
How Is Your Tax Bill Calculated?
The assessor's office uses this formula for their tax calculations: Taxable value (according to HCAD) × tax rates (from taxing units) = final bill.
Quick estimate using the county median effective rate (already reflects typical exemption patterns in Trends data):
Input | Amount |
|---|---|
Illustrative home value (Harris median) | $275,000 |
1.49% | |
Estimated annual bill | $275,000 × 1.49% ≈ $4,098 |
Harris median bill on Trends (for comparison) | $3,916 |
Your account will not match the median exactly. School district, city limits, MUDs, and exemptions all move the needle.
Stacked statutory rates (tax year 2025, per $100 of taxable value) for a Houston + Houston ISD-style stack, from the Texas Comptroller’s published local property tax rates:
Taxing Unit | Rate (per $100) |
|---|---|
Harris County | 0.38096 |
Harris County Flood Control | 0.04966 |
Port of Houston Authority | 0.0059 |
Harris County Hospital District | 0.18761 |
Harris County Department of Education | 0.004798 |
City of Houston | 0.51919 |
Houston ISD | 0.8783 |
Houston Community College | 0.098802 |
Illustrative stack (no MUD) | ≈ 2.125 per $100 (about 2.13% before exemptions) |
Other districts run higher on the school line alone:
Cypress-Fairbanks ISD: about 1.0669 per $100
Katy ISD: about 1.1171 per $100
Those school rates apply before city, county, and special-district layers. Neighboring streets can diverge when one home sits in a MUD or a different ISD.
Taxing units are the different government entities that collect revenue from taxpayers. The total tax rate is the sum of all the rates from these local units, including:
Houston Independent School District (ISD) or your associated school district
City of Houston or your municipality
Harris County
Harris County Flood Control District
Hospital, port, community college, and special districts such as MUDs where they apply
While each government office or agency collects its own taxes, lowering your HCAD value reduces the amount you pay to all of them. As a result, your savings compound across all units if you can lower your home's taxable value.
How To Pay Your Property Taxes
Although you should receive a paper bill for your property taxes, you can look up a digital version online at MyHarrisCountyTax or the Harris County Tax Office website. The site will also show rate details on your account and when your taxes are due. 2026 taxes are due January 31, 2027, in the normal cycle. Paying on time prevents penalties and interest after delinquency.
You have several payment options, including e-checks, credit cards, and debit cards. Alternatively, you can pay over the phone via credit or debit card, mail a check, or visit the tax office to pay in person. The Tax Office also publishes installment plan options if you need a structured path after a large bill.
Which Exemptions Can Lower My Harris County Tax Bill?
Unsure which exemptions you qualify for? Find out in 60 seconds if you're missing homestead savings
A property tax exemption saves you money on taxes by reducing the taxable value of your home. These are the most common and beneficial exemptions for homeowners in Harris County:
The General Residential Homestead Exemption is the foundational exemption available for primary residences. If you qualify, you'll receive a school district exemption of at least $140,000, and any taxing unit can offer an additional exemption of up to 20% of your home's value. Homestead status also unlocks the 10% annual cap on increases in the value used for taxation.
The Over-65 Homeowners Exemption and Homeowners with Disabilities Exemption are available if you're over 65 years old or have a documented disability. Under these exemptions, school districts give an automatic $60,000 exemption; other taxing units may offer an exemption of at least $3,000; your school taxes won't increase unless you make home improvements (the school tax ceiling); and you can indefinitely defer your tax payments with interest.
The 100% Disabled Veteran's Homestead Exemption applies if you receive full disability payments from the Veterans' Administration due to a service-related condition. It exempts 100% of your home's value.
For the general homestead, you generally must own and occupy the home as your principal residence on January 1. Homestead exemptions don't automatically apply to your tax bill, so you'll need to apply if you meet the eligibility requirements.
The deadline for a new exemption application is typically April 30 each year. The 2026 window has passed for a standard new filing year; plan for April 30, 2027 on the next cycle, and note that some late or corrected homestead filings can still be accepted after that date depending on HCAD rules. File with HCAD using the statewide homestead application, Form 50-114, or through the HCAD forms index. The Texas Comptroller also maintains a full exemptions overview if you need the statewide rules in one place.
After applying, check your homestead status with HCAD's property search tool. For a deeper walkthrough of amounts and stacking rules, see our Harris County homestead exemption guide. In Texas, we can also help capture missed homestead filings retroactively where you qualify.
Unsure Which Exemptions You Qualify For?
How Do I Protest My Property Value in Harris County?
Exemptions are often the first step in lowering your bill, but if the underlying appraised value is too high, you'll need to protest your Harris County appraisal. Filing a Harris County tax appraisal protest lets you dispute the value HCAD assigned to your home.
According to our Texas Protest vs. Non-Protest Study, only 33% of Harris County residential properties protested in 2025. That left 856,268 homes unprotested and about $267.9 million in potential savings on the table.
Across 2023-2025, Harris County protesters realized about $443.1 million in tax savings, while non-protesters left an estimated $685.3 million unclaimed. In 2025, successful protests averaged a 7.4% value reduction with an 87% win rate.
Use this sequence when you decide to file a Harris County property tax protest:
Review the notice for data errors. Confirm square footage, condition, and property details before you argue value.
Choose your grounds. Market value (the home would not sell for HCAD’s number) and unequal appraisal (similar homes are appraised lower) are the workhorses. Unequal appraisal is often the strongest path when comps support you.
Gather evidence. Comparable sales or appraisal schedules, repair estimates, and photographs of damage or deferred maintenance help. The most common approaches to reducing your bill still turn on market value and unequal appraisal proof.
File on time in iFile. The 2026 deadline was May 15, 2026, or 30 days after the notice was mailed. For 2027, expect the same pattern: around May 15, 2027, or within 30 days after HCAD mails your next notice, whichever is later. Submit through HCAD’s iFile and iSettle system, or mail Form 50-132 (Notice of Protest). The clock runs from mailing, not from when you open the envelope.
Consider iSettle. On the same portal, iSettle can resolve some protests if you accept HCAD’s settlement offer.
Prepare for the Appraisal Review Board (ARB) if needed. If you do not settle, you may attend an ARB hearing to present evidence.
Know the next rungs at a high level. After the ARB, limited paths such as binding arbitration, SOAH in some cases, or district court exist. Most homeowners resolve the dispute at informal review, iSettle, or the ARB.
If you decide to protest, collect strong evidence showing flaws in the HCAD valuation before you click submit. A tight set of comps usually beats a thick folder of weak ones.
Missed the Deadline? Here’s How To Plan for 2027
The 2026 protest deadline has passed for most accounts. You can still prepare to save money in the 2027 cycle. Start by verifying your exemptions. Ensure you've claimed all the available exemptions you're eligible for, such as Harris County homestead exemptions. You can file some of these exemptions year-round rather than waiting for the next deadline.
Then, make sure you know when property taxes are due in Harris County, Texas. In the normal cycle, 2026 taxes are due January 31, 2027, so you can pay on time. Set a reminder for the expected May 15, 2027 protest deadline (or the 30-day mailed-notice rule) so you are ready when HCAD sends the next Notice of Appraised Value.
