One of the first questions we hear from buyers relocating to Houston — and even from local buyers who have been renting — is about property taxes. Texas has no state income tax, and the trade-off is that property taxes fund a significant portion of local services, including schools, roads, and emergency services. If you are buying a home in Houston Heights, Garden Oaks, Oak Forest, or anywhere in Harris County, understanding how property taxes work is essential to making a sound financial decision.
Here is what every buyer needs to know about property taxes and the homestead exemption in Houston for 2026 — including the significant changes that took effect this year.
How Property Taxes Work in Harris County
In Texas, there is no single statewide property tax rate. Your total tax rate is the combined sum of every taxing jurisdiction that serves your property. For a typical home in the Houston Heights or Inner Loop area, your tax bill includes rates from:
- Houston ISD (or your local school district): approximately $0.88 to $0.96 per $100 of assessed value
- City of Houston: approximately $0.52 to $0.55 per $100
- Harris County: approximately $0.38 to $0.39 per $100
- Flood Control, Port, and other special districts: smaller rates that add roughly $0.06 to $0.08 per $100
Combined, the effective property tax rate for most Houston Heights and Inner Loop homes lands between 2.0% and 2.1% of your home's appraised value per year. For a home valued at $650,000, that means an annual tax bill of approximately $13,000 to $13,650. For a $1 million home, the range is roughly $20,000 to $21,000.
These numbers underscore why understanding exemptions and the appraisal process is so important. Every dollar of exemption reduces your taxable value, and every dollar of over-appraisal that you successfully appeal saves real money.
The Big Change: $140,000 School District Exemption (2026)
The most significant property tax reform in years took effect on January 1, 2026. Texas voters approved Proposition 13 in November 2025, which increased the mandatory school district homestead exemption from $100,000 to $140,000. This means that if you own and occupy your home as your primary residence, your school district taxes are calculated on your home's appraised value minus $140,000 — not the full value.
For a home appraised at $650,000, that $140,000 exemption saves you roughly $1,260 to $1,344 per year in school taxes alone. Over the life of a 30-year mortgage, that adds up to more than $37,000 in savings.
Harris County's Optional 20% Exemption
In addition to the school district exemption, Harris County offers a 20% optional homestead exemption on the county portion of your taxes. This reduces your home's appraised value by 20% (minimum $5,000) for county tax purposes. The City of Houston and other taxing entities may also offer their own optional exemptions, so it pays to understand exactly which exemptions apply to your specific property.
The 10% Appraisal Cap: Your Built-in Protection
One of the most valuable protections for Texas homeowners is the 10% appraisal cap. Under state law, the appraised value of a homestead property cannot increase by more than 10% per year — regardless of how much the market value of your home goes up. This means that even if property values in your neighborhood surge 20% in a year, your taxable value can only rise by 10%.
This cap is one reason why long-term homeowners in rapidly appreciating neighborhoods like Houston Heights often pay significantly less in property taxes than a new buyer purchasing a comparable home next door. The new buyer's taxable value resets to the purchase price, while the long-term owner's value has been capped year after year.
Filing Your Homestead Exemption
Filing for your homestead exemption is straightforward, but it does not happen automatically. You must file Form 50-114 with the Harris County Appraisal District (HCAD). The deadline is April 30 of the tax year for which you are claiming the exemption. If you buy a home mid-year, you have until April 30 of the following year to file.
You only need to file once; the exemption remains in effect as long as you own and occupy the home. If you move to a new primary residence, you must file a new application for that property.
What About Senior and Disabled Homeowners?
For homeowners aged 65 or older, or those with qualifying disabilities, the exemptions are even more generous. Under Proposition 11 (also approved in November 2025), seniors and disabled homeowners receive an additional $60,000 school district exemption, bringing their combined school exemption to $200,000. Harris County also provides an additional $160,000 reduction on county taxes. For seniors with homes valued at $286,250 or less, the county tax liability may be fully eliminated.
Protesting Your Appraisal
If you believe your home's appraised value is too high, you have the right to protest. HCAD sends out appraisal notices in the spring, and you typically have until May 15 (or 30 days from the notice date, whichever is later) to file a protest. Many homeowners successfully reduce their appraised values by providing comparable sales data or pointing out condition issues. Our team works with property tax professionals who can help you navigate this process.
