Aug. 17: The Deadline That Sets Your November Tax Ballot

The Texas tax rate election deadline is Aug. 17, 2026 — the last day a school district, city or county can put a tax hike on your Nov. 3 ballot.

Your property tax bill won’t arrive until October, and it isn’t due until January 31. But whether you get to vote on part of it is settled this week: the Texas tax rate election deadline is Monday, August 17, 2026.

That Monday is the last day a Texas school district, city, county or special district can order an election to be held on the November 3 ballot. After Monday, the November ballot is fixed. Any taxing unit that wanted to raise your rate above the level state law lets it set on its own — and didn’t order the election by that day — has lost the option for the entire 2026 tax year.

Here is the chain of deadlines that quietly decides this, why it starts far earlier than most homeowners realize, and what two large districts just did with days to spare.

Why the Texas tax rate election deadline is the 78th day

Texas law gives taxing units a calculated ceiling called the voter-approval tax rate — described by the Texas Comptroller as “a calculated maximum rate allowed by law without voter approval.” Go above it, and the voters get a say.

That say has a filing deadline. Under Tax Code § 26.07(c) and § 26.08(b), when a taxing unit adopts a rate above the voter-approval rate it “must hold an election on the next uniform election date,” and the order calling that election “may not be issued later than the 78th day before the date of the election.”

The Election Code sets the same wall for elections generally. The Secretary of State’s own November 3, 2026 Election Law Calendar puts it on a specific date — Monday, August 17, 2026 — with this entry:

“Deadline for political subdivisions to order a general election to be held on Tuesday, November 3, 2026. (Sec. 3.005).”

Seventy-eight days before November 3 is August 17. That is the whole of it. There is no grace period, no late filing, and no second uniform election date in the fall.

The second deadline, one week later

Ordering the election is not the same as adopting the rate. Those are two separate acts with two separate deadlines, and the order comes first.

The Comptroller’s truth-in-taxation guidance spells out the ordinary rule: a taxing unit must “adopt its tax rate before Sept. 30 or by the 60th day after the taxing unit receives the certified appraisal roll” (Tax Code § 26.05(a)). But when the rate requires an election, the clock tightens — the governing body must “adopt the tax rate no later than the 71st day before the next uniform election date.”

Seventy-one days before November 3 is Monday, August 24, 2026. In practice most boards do both at the same August meeting, which is exactly what happened this month.

The gate almost nobody sees: the efficiency audit

For school districts, the August deadlines are not the first gate. They are the last one.

Since the 2019 school-finance overhaul, a district cannot ask voters to ratify a higher maintenance-and-operations rate without first submitting to an outside review of its own spending. Texas Education Code § 11.184 defines an efficiency audit as “an investigation of the operations of a school district to examine fiscal management, efficiency, and utilization of resources,” and attaches a schedule to it:

Run those against this cycle. Four months before November 3, 2026 is July 3, 2026. A school district that had not already hired an efficiency auditor by that date had, without any public vote being taken, already lost the ability to put a tax-rate question on the November ballot — a month and a half before the deadline anyone reports on.

The results-posting deadline lands 30 days out, on October 4, 2026. If your district is holding a tax-rate election this fall, that audit is a public document, and it is the single most useful thing you can read before voting.

There is one carve-out: § 11.184 allows districts wholly or partly inside a governor-declared disaster area to hold a rate-ratification election “during the two-year period following the date of the declaration without conducting an efficiency audit.”

What it looked like this month

Two of the state’s larger districts cleared the August 17 wall by a week — both on the same night, Monday, August 10, 2026.

Bryan ISD (Brazos County)

The Bryan ISD board unanimously ordered a voter-approval tax rate election for November 3. According to local coverage of the vote, the district is asking voters to move its maintenance-and-operations rate from $0.6769 to $0.6968 per $100 of taxable value, and estimates the increase would generate about $5.5 million a year in recurring revenue that is not subject to state recapture.

Two notes a homeowner in Brazos County should have. First, the increase is usually reported as “2 cents”; the actual arithmetic is 1.99 cents ($0.6968 − $0.6769 = $0.0199). Second, the “not subject to recapture” line is doing real work. Certain pennies of a district’s M&O rate stay home rather than being routed back to the state — the mechanism we explain in our piece on Robin Hood recapture. That is why districts reach for these particular pennies.

Bryan voters separately approved a $397 million bond package in November 2025. That was the debt-service side of the rate. This November’s question is the operating side — a distinction worth keeping straight, because they are funded by two different halves of the same tax rate.

Cy-Fair ISD (Harris County)

The Cypress-Fairbanks ISD board voted 6–1 on August 10, 2026 to place both a 12-cent voter-approval tax rate election and a $1.63 billion bond package on the November 3 ballot, according to reporting on the meeting. The bond is split across multiple propositions covering facilities and buses, instructional technology, athletic facilities, and swimming facilities.

The district’s stated net effect is a roughly 9-cent increase for Harris County taxpayers in the district — the 12-cent operating increase partially offset by a projected 3-cent reduction on the debt-service side. Board discussion of the package began at an August 6 work session, four days before the vote and eleven days before the deadline.

A third district, South San Antonio ISD in Bexar County, has been reported since June to be planning a different kind of question: shifting roughly 7 cents from its debt-service rate to its operating rate so the total rate stays flat while freeing money for salaries and deferred maintenance. We could not confirm from a primary source that South San’s board has formally ordered that election, so treat it as proposed rather than called until the district’s own election order is posted.

What happens to the districts that miss the date

Nothing dramatic — and that is the point. A taxing unit that does not order an election by August 17 is simply capped. It can adopt any rate up to its voter-approval rate, and not a penny more, for the 2026 tax year. Its budget gets balanced somewhere other than your tax bill: reserves, cuts, or deferral to next year.

There is also a penalty for blowing the ordinary adoption deadline entirely. Under Tax Code § 26.05(c), a unit that misses it must ratify either the no-new-revenue rate or the prior year’s rate — whichever is lower — within five days.

And if the election happens and voters say no, the answer sticks. Per Tax Code § 26.08(d) and § 26.07(e), “if the voters disapprove the adopted tax rate, the governing body may not adopt a tax rate that exceeds the voter-approval tax rate.”

One further wrinkle applies to bonds: the Secretary of State’s calendar flags a new law, HB 2253 (2025), allowing the authority that ordered a bond measure to cancel that election as late as the 74th day before election day. A called bond election is not quite irreversible; a called tax-rate election effectively is.

Why any of this is happening in 2026

It is a fair question why districts are asking for more when the state spent 2025 advertising tax relief — including the $140,000 school homestead exemption that took effect for the 2025 tax year.

The two things are not in tension. The exemption cut what homeowners owe on a given rate; it did not increase what districts collect per penny, and it did not touch the cost of staffing a school. Where taxable values have fallen, the same rate now raises less money than it did last year — which is how a district can face a shortfall in a year the state calls a tax cut. We walked through that mechanism in our guide to the summer rate-setting season, and through last year’s wave of these elections in our look at the 2025 VATREs.

What to do this week

What we could not verify

In keeping with this site’s practice, the gaps are stated rather than papered over. The Bryan ISD and Cy-Fair ISD figures above come from press reports of the August 10 board meetings, not from the districts’ filed election orders, which were not posted at the time of writing. South San ISD’s 7-cent swap is reported but we could not confirm the board has ordered the election. The exact calendar placement of the HB 2253 bond-cancellation deadline should be checked against the Secretary of State’s calendar directly. Verify any figure that affects your own bill against your taxing unit’s truth-in-taxation notice or your county appraisal district.
