Understanding Houston property taxes is essential for effective financial planning, whether you’re a first-time homebuyer in the Houston area or a longtime homeowner managing your annual costs. Here’s a comprehensive breakdown of how Harris County property taxes work, what you can expect to pay, and how to stay ahead of key deadlines.
What Are Property Taxes?
Property taxes are annual charges levied by local government entities based on the assessed value of your property. In Harris County, these taxes fund critical public services including education, public health, road maintenance, flood control, and emergency services, all of which directly shape the quality of life in Houston.
Your property’s value is assessed each year by the Harris Central Appraisal District (HCAD). That assessed value is then multiplied by the combined tax rates of all applicable taxing units, Harris County, the City of Houston, your school district, and any special districts, to determine your total tax bill.
How Much Is Property Tax in Harris County?
Your total tax bill reflects the combined rates of every taxing entity that applies to your property. For reference, the 2025 base rates for the three largest taxing units in Houston are:
- Harris County: $0.6241 per $100 of assessed value
- City of Houston: $0.51919 per $100 of assessed value
- Houston ISD: $0.86830 per $100 of assessed value
When these and other local district rates are combined, the overall effective property tax rate for most Houston homeowners is approximately 1.46% of assessed value, well above the national average but lower than the 2% figure often cited for Texas as a whole.
Because rates are set annually by each taxing entity and your home’s assessed value is updated each year, your bill may change even if you haven’t made improvements to your property. You can look up your specific account and estimated bill through the HCAD online portal.
When Are Harris County Property Taxes Due?
Harris County property taxes are billed starting in October and are due in full by January 31. Delinquency begins on February 1, at which point penalties and interest start accruing immediately.
Not receiving a bill does not excuse a late payment. Property owners are responsible for paying on time regardless. If your bill hasn’t arrived by mid-December, look up your account online or contact the Harris County Tax Office directly.
If your property qualifies, installment payment options may be available. Homeowners who are over 65, disabled, or whose homestead was affected by a qualifying state disaster declaration may pay in quarterly installments. Note that installment payments under a delinquency agreement accrue a 7% charge in addition to standard penalties. Contact the Tax Office to confirm eligibility and enrollment deadlines.
Can I Pay My Harris County Property Tax Bill Online?
Yes. The Harris County Tax Office offers a dedicated online payment portal. You can pay by credit card, debit card, eCheck, or PayPal. Creating an account allows you to set up payment reminders, save receipts, and manage multiple properties. A convenience fee applies for credit/debit card payments; eCheck payments carry a lower fee and generate an immediate paid receipt.

Property Tax Exemptions in Harris County
Several exemptions can meaningfully reduce your taxable value. Here is what is available for the 2025-2026 tax year.
General Homestead Exemption: As of the 2025 tax year, the school district homestead exemption is $140,000, increased from $100,000 in 2023 following a voter-approved increase in November 2025. To qualify, the property must be your primary residence as of January 1 of the tax year. Applications must be filed with HCAD by April 30 for the current tax year.
Over-65 and Disabled Person Exemption: Homeowners who are 65 or older or have a qualifying disability receive an additional $60,000 exemption off school district taxable value. This brings the combined school tax exemption total to $200,000. Seniors with this exemption also receive a school tax ceiling, meaning their school district taxes cannot increase as long as they own and occupy the home, even if the property value rises.
Disabled Veteran Exemptions: Partial to full exemptions are available depending on the disability rating assigned by the VA.
Additional local exemptions: Some taxing entities in Harris County offer their own optional exemptions on top of the state-mandated amounts. Check with HCAD to see what applies to your property.
10% Annual Appraisal Cap: Once a homestead exemption is in place, Texas law limits the annual increase in your home’s appraised value to no more than 10% per year for tax purposes, regardless of how much market values have risen. This protects homeowners from sharp single-year spikes in their tax bill.
To apply, submit your application to the Harris Central Appraisal District. Applications open January 1 and must be filed by April 30 for the current tax year. Texas law requires appraisal districts to verify homestead eligibility at least once every five years. Respond promptly to any verification mailings from HCAD to avoid having your exemption removed.
How to Protest Your Harris County Property Tax Assessment
Every year, HCAD mails a Notice of Appraised Value to property owners in late March or early April. This notice shows HCAD’s estimate of your property’s market value as of January 1. If you believe the value is too high, you have the right to protest, and there is no risk in doing so. HCAD cannot raise your value as a result of filing a protest.
The protest deadline is May 15, 2026, or 30 days after your notice is mailed, whichever is later. Missing the deadline means you are locked into HCAD’s value for the entire tax year.
Step-by-Step Protest Timeline
| STEP | ACTION | TIMELINE |
|---|---|---|
| 1 | Receive your Notice of Appraised Value from HCAD | Late March to Early April |
| 2 | Review your property details on hcad.org for errors (square footage, room count, lot size) | Immediately after receiving notice |
| 3 | File your protest online through HCAD's iFile system at owners.hcad.org | Before May 15, 2026 |
| 4 | Upload supporting evidence (comparable sales, photos, repair estimates) | Within 5 calendar days of filing |
| 5 | Review iSettle offer from HCAD (if one is made) | 2 to 4 weeks after filing |
| 6 | Accept the offer, or attend your Appraisal Review Board (ARB) hearing | Typically June to July |
What Evidence to Prepare
A well-supported protest gives you the best chance of a reduction. The most effective types of evidence include:
- Comparable sales data: Ask a local real estate agent for a comparative market analysis (CMA) showing recent sales of similar homes in your area at a lower value than your assessment.
- Photos of property condition: Document any maintenance issues, deferred repairs, or structural concerns that reduce market value.
- Contractor estimates for needed repairs: Written estimates from licensed contractors can substantiate condition-related value reductions.
- Corrections to property record errors: If HCAD’s records show the wrong square footage, room count, lot size, or property classification, a factual correction alone can be enough to reduce the assessed value.
Filing online through HCAD’s iFile system is the fastest method and provides immediate confirmation of your filing.
What Happens If My Houston Property Tax Payment Is Late?
If your payment is not received by January 31, a 6% penalty plus 1% interest is added to your balance starting February 1. Interest continues to accrue at 1% per month. If taxes remain unpaid through July 1, an additional penalty of up to 20% may be added to cover collection costs. Partial payments are accepted and will reduce the total penalties accruing on the unpaid portion.
Does My Mortgage Lender Pay My Property Taxes?
If your mortgage includes an escrow account, your lender collects a portion of your estimated annual property tax bill with each monthly payment and pays it to the Harris County Tax Office by the January 31 deadline on your behalf. Review your annual escrow analysis statement to confirm the correct amount is being collected, particularly if your assessed value or exemption status has changed.
