Is your bill fair and equal this year?
You may be overassessed. A $30,000 overvaluation costs you about $700 every single year, and compounds each year you don't challenge it. Ownwell can tell you in seconds.
Where Harris County Tax Bills Stand in Texas
Harris County is the most populous county in Texas. With no state income tax, Texas funds public services almost entirely through property taxes, and Harris County homeowners feel that burden acutely.
Complex Taxing Structure
Multiple MUDs, school districts, and emergency services districts stack on top of each other. Every dollar of overassessment is multiplied across five or six taxing entities simultaneously.
Mass Appraisal Limitations
HCAD values hundreds of thousands of properties using statistical models, not individual inspections. Flood damage, foundation issues, and hyperlocal market factors are frequently missed.
Rising Assessments, 20% Cap for Most Non-Homestead Properties
Texas caps annual assessed value increases at 10% for homesteaded properties. Most non-homestead properties under $5M have a 20% circuit breaker cap (effective through 2026).
Flood & Storm Damage Gaps
Houston's recurring floods leave lasting damage that HCAD's models often don't capture. Foundation issues, mold history, and drainage problems can significantly reduce your property's actual market value.
Harris County Property Tax Rates by Taxing Entity
Your total Harris County property tax bill is calculated by multiplying your assessed value by the combined rate of all applicable taxing entities.
Every property is subject to multiple overlapping jurisdictions — the county, your municipality, your school district, and potentially additional special districts like MUDs or hospital districts.
| Taxing Entity | 2025 Rate (per $100 assessed value) | Notes |
|---|---|---|
| Harris County | ~$0.37 | Approximate; subject to annual adjustment |
| Harris County Flood Control | $0.04966 | Applies countywide |
| City of Houston | ~$0.53 | City of Houston residents only |
| Houston ISD | $0.8783 | Largest single component for most homeowners |
| Spring ISD | $1.1369 | North Harris County |
| Katy ISD (Harris portion) | $1.1171 | West Harris County |
| Clear Creek ISD | $0.969 | Southeast Harris County / NASA area |
| MUD / Special Districts | Varies by location | Can add 0.5%-1.0%+ to your effective rate |
| Typical Combined Rate | 2.1% - 2.5% | Varies by address; among highest in Texas |

How HCAD Calculates Your Assessed Value and What Can Go Wrong
Two values appear on your notice: market value and assessed value. For homesteaded properties, the 10% annual cap means your taxable assessed value can rise no more than 10% per year — even if your market value rose 25%. For non-homesteaded properties, there is a 20% cap on properties under $5 million.
Scale-Driven Errors
HCAD values over 1.8 million properties. Even a 5% error rate means 90,000+ properties are overvalued in any given year.
Neighborhood Boundary Issues
HCAD draws broad neighborhood boundaries for mass appraisal. Homes at the edges may be compared to properties in very different micro-markets.
Condition & Maintenance Ignored
Deferred maintenance, aging systems, and functional obsolescence are rarely captured by HCAD's automated valuation models.
iSettle Offers Are a Starting Point
HCAD's iSettle system resolves protests quickly — for the district. Most homeowners accept the first offer. Ownwell analyzes every offer against market data and pushes further when warranted.

Harris County Exemptions You May Be Missing
Exemptions reduce your taxable assessed value before the tax rate is applied. Filing for every exemption you qualify for — and protesting your assessed value — works together to minimize your bill. Ownwell can help you identify and file for the missed general homestead exemption for up to two years.
School district taxes reduced by $140,000 for your primary residence (new for 2026). File by April 30. Available to all primary residence owners.
Additional $60,000 reduction on school district taxes, plus a tax ceiling that freezes your school district tax amount. Applies to qualified seniors and disabled homeowners.
Partial or full exemption based on VA disability rating. Veterans with a 100% disability rating pay zero property tax in Texas. Surviving spouses may also qualify.
