"Please understand the tax rate that we will be considering in just a few short weeks is probably the greatest tax rate increase in the history of Harris County."
Precinct 3 Commissioner Tom Ramsey said that to a room of Harris County residents in early August, and he wasn't talking about a school district or a municipal utility district tucked inside one subdivision. He was talking about the plain "Harris County" line that shows up on every tax bill in the county, whether the home sits in Bellaire, unincorporated Cypress, or a new build off the Grand Parkway.
Anyone comparing homes across Harris County this fall has probably already glanced at an effective tax rate on a portal or a calculator. That number isn't wrong exactly. It's just not finished. Commissioners Court hasn't cast its final vote yet, and the timeline for that vote runs straight through the middle of house-hunting season.
One line, four separate decisions
Most homeowners think of "Harris County" as a single taxing authority. It isn't. Commissioners Court sets four separate rates every year that get folded into one combined figure on the bill: the county's general fund, the Harris County Flood Control District, Harris Health (the county hospital district that runs Ben Taub and Lyndon B. Johnson hospitals), and the Port of Houston Authority. Each one gets its own public hearing, its own vote, and in some years its own election.
That matters because the four rates don't move together. Here's how they shifted between the current fiscal year and the one before it, based on the rates Commissioners Court adopted last fall:
| Component | FY2024-25 rate | FY2025-26 rate |
|---|---|---|
| General fund (implied) | about $0.385 | about $0.381 |
| Flood Control District | $0.04897 | $0.04966 |
| Harris Health | $0.16348 | $0.18761 |
| Port of Houston Authority | $0.00615 | $0.00590 |
| Combined | $0.6038 | $0.6241 |
The general fund figures aren't published on their own. They're what's left after subtracting the three special districts from the official combined rate, and the math is telling. The county's own operating rate barely moved. The Port's rate actually went down. The entire year-over-year increase came from Harris Health and Flood Control, two entities most buyers have never researched before making an offer.
Why the rate is already trending up again
Harris County is heading into a projected general fund shortfall for the fiscal year that starts October 1, 2026, an estimate that's already been revised once this year, from as high as $257 million in a May projection down to $178 million by mid-August. OMB Director Daniel Ramos told Commissioners Court on August 17 that roughly 88 percent of the year-over-year budget increase isn't new spending. It's the cost of keeping current staffing, pay commitments, and services running at their existing level.
To close the gap, Ramsey has floated a three-cent increase to the general fund rate, and said Flood Control and Harris Health are each weighing matching three-cent increases of their own. If all three move, the combined rate climbs from roughly 62 cents to 71 cents per $100 of value, the increase Ramsey called potentially the largest in county history. Commissioners Court is scheduled to work through budget amendments on September 8 and cast the formal adoption vote, including the final tax rate, on September 17.
The pattern already has a track record
This wouldn't be the first time one of the four component rates moved by a wide margin while the general fund stayed put. Flood Control's rate jumped by roughly 58 percent after Harris County voters approved Proposition A in November 2024, a measure county officials described at the time as a transformational rate for the district's flood mitigation work.
Harris Health's debt service rate spiked even more sharply the year before that. Voters approved a hospital district bond in November 2023 to fund a new level-1 trauma center at Lyndon B. Johnson Hospital along with renovations at Ben Taub, and the debt-service portion of the hospital district's rate rose by roughly 550 percent to start paying that bond down.
Neither of those increases touched the general fund. Both of them touched every homeowner's bill.
What this means if you're shopping or closing this fall
The county's own budget office has already run one preview number. For a primary residence valued around $402,000, the county estimated its own general fund tax alone would climb from about $1,202 to $1,350 a year under the proposed rate, after the standard 20 percent homestead exemption. That figure doesn't include Flood Control, Harris Health, or the Port. A separate estimate circulated in mid-August put the impact on a median-valued homestead at roughly $90 more a year from the county's general fund rate alone, climbing to about $97 once the proposed Flood Control increase is factored in. Depending on where Harris Health's rate lands on September 17, the real number could sit above both of those estimates.
None of this gets offset by the new $140,000 school district homestead exemption Texas voters approved in November 2025 for the 2026 tax year. That exemption reduces the school district portion of a bill. It does nothing to the four county rates described above, because those are calculated against a separate taxable value.
A few things worth doing before you lock in a number:
- Ask whether your lender's escrow analysis is using last year's combined rate or building in room for the September 17 vote.
- Confirm whether the home you're considering sits inside Houston city limits, which adds the city and Houston Community College rates on top of the county's four, or in unincorporated Harris County, which may carry an emergency services district rate instead.
- If your closing lands after September 17, your first full tax cycle in the home will reflect whatever Commissioners Court actually adopts, not the estimate you saw when you toured the property.
- Remember that Flood Control and Harris Health move independently of the county's general fund and of each other. A quiet year for one doesn't guarantee a quiet year for all four.
A short FAQ
Does this increase apply the same way to every home in Harris County? The four component rates apply countywide. What ends up on a specific bill still depends on which city, which school district, and whether any municipal utility district or emergency services district also taxes that property.
Is this the same thing as a MUD tax? No. Municipal utility districts are separate special-purpose entities tied to specific subdivisions, mostly in unincorporated areas. The county's four rates sit on top of, or alongside, whatever MUD levy a property carries. They aren't a substitute for one another.
When will the actual 2026 rate be final? Commissioners Court is scheduled to adopt the FY2026-27 budget and the year's final combined tax rate on September 17, 2026, following budget amendment discussions on September 8.
