Property Taxes in Houston
Property taxes are the single biggest ongoing cost surprise for many Houston homeowners, and sources disagree meaningfully on the precise effective rate: figures ranged from about 1.49% to just over 2% of market value this session, with one synthesis putting most Harris County homeowners around 1.8%-2.0%. What's not in dispute is the mechanism -- a typical Houston homeowner pays into seven or more overlapping taxing entities at once, and the state's homestead exemption and appraisal cap were both meaningfully expanded for 2026.

Learn moreSeven or More Overlapping Taxing Entities
A typical Harris County homeowner pays property tax to multiple layers at once: Houston ISD (or another local school district), the City of Houston (or none, if unincorporated), Harris County itself, Harris Health (the county hospital district), the Harris County Flood Control District, the Port of Houston Authority, and the Harris County Department of Education (HCDE) -- seven distinct entities, per property-tax research aggregators reviewed August 2026. Each sets its own millage-equivalent rate annually; the combined total, not any single entity's rate, is what determines the actual bill.
Effective Rate: A Real, Wide Disagreement
Sources disagreed more here than is typical: Ownwell cited a median Harris County effective property tax rate of 1.49%; a separate source cited 1.72%; another cited approximately 2.03% ($2.03 per $100 of taxable value); and a fourth synthesis described a combined range of 1.8%-2.4% with most Harris County homeowners landing around 1.8%-2.0%. None of these is a direct pull from the Harris County Appraisal District for a specific parcel -- confirm your actual parcel's current combined rate against HCAD directly rather than relying on any single aggregated figure, including this range.
Homestead Exemption: Meaningfully Larger for 2026
The mandatory school-district homestead exemption jumped from $100,000 to $140,000 for the 2026 tax year, following Proposition 13, approved by Texas voters in November 2025 -- a real, recent increase, not a legacy figure to treat with suspicion. Homeowners 65 or older or disabled receive an additional $60,000 on top of that, for up to $200,000 total exempted from school-district taxes. This exemption applies only to school-district levies specifically; it does not reduce the county, city, or special-district portions of the bill the same way.
Texas's 10% Appraisal Cap (Not Florida's Save Our Homes, But a Similar Idea)
Once a homestead exemption is on file with the county appraisal district, Texas Tax Code §23.23 caps how fast the assessed (taxable) value of that home can rise year to year at 10% maximum, regardless of how much the market value actually moves. This is a meaningfully looser cap than Florida's Save Our Homes limit (3% or CPI, whichever is lower) -- it still protects against a sudden appraisal spike, but a Texas homeowner in a fast-appreciating Houston neighborhood can still see real, compounding assessed-value growth year over year in a way a Florida homesteaded owner would not.
MUD Taxes Stack on Top in Many Suburbs
Homeowners in a Municipal Utility District (common in suburban Houston-area developments like parts of Katy and Cypress -- see the moving topic page) pay an additional MUD tax on top of the standard county/city/school layers, funding the district's water, sewer, and drainage infrastructure debt. MUD rates vary significantly by district and generally decline over time as the district pays down its bonds, but a new or heavily bonded MUD can add a real, non-trivial amount to a total property tax bill -- confirm the specific district's current rate before buying, not after.
Key takeaways
- Harris County homeowners typically pay into seven or more overlapping taxing entities (school district, city or none, county, hospital district, flood control district, port authority, HCDE) at once.
- Sources disagreed meaningfully on the effective rate this session (1.49% to just over 2%, with most homeowners estimated around 1.8%-2.0%) -- confirm your specific parcel's rate with the Harris County Appraisal District.
- The school-district homestead exemption rose from $100,000 to $140,000 for 2026 (Proposition 13, approved November 2025); homeowners 65+ or disabled get an additional $60,000 (up to $200,000 total).
- Texas's 10% annual appraisal cap (for homesteaded properties) is real protection but looser than Florida's 3%/CPI Save Our Homes cap -- expect more year-over-year assessed-value growth here than in a comparable Florida market.
- Homes in a Municipal Utility District (common in suburban Houston) carry an additional MUD tax on top of standard property taxes -- confirm the specific district's rate before buying.
