Dallas County Property Tax Bills 2026: When They Arrive, Rate After Prop A, Due Date

Last updated November 6, 2026.

Dallas County 2026 property tax bills were held until after the Nov. 3 Proposition A election. Voters rejected the higher rate, so the county rate is the voter-approval rate of $0.224650 per $100 of taxable value—not the $0.248650 rate on the ballot. Bills should mail now; pay by Jan. 31, 2027 (listed as Feb. 1, 2027 when Jan. 31 falls on a Sunday).

This guide covers when Dallas County bills arrive, which county rate applies after Proposition A, the payment deadline, and what you can still do about the taxable value behind the bill.

When do Dallas County property tax bills arrive in 2026?

In a normal year, Dallas County mails statements in October. For 2026, Tax Assessor John Ames said bills would not go out in October because voters had to decide Proposition A on Nov. 3. The county calculated tentative amounts offline, and anyone checking early online could have seen a higher figure before Election Day.

With the election over, corrected statements can go out. Check the Dallas County Tax Office statements page and your mailbox or escrow notice. If you pay yourself (no escrow), set money aside now—the window between mailing and the due date is shorter than usual.

What county tax rate applies after Proposition A failed?

Dallas County’s Truth-in-Taxation listing for tax year 2026 shows three key county rates per $100 of taxable value:

• No-new-revenue rate: $0.203785
• Voter-approval rate: $0.224650
• Adopted (election) rate on the ballot: $0.248650

Commissioners adopted $0.248650 and called a tax-rate election because that figure sits above the voter-approval rate. Unofficial results show Proposition A failed. Under Texas Tax Code Chapter 26, when voters reject the higher rate, the unit uses the voter-approval rate—so the county portion for 2026 is $0.224650, not $0.248650.

That is still above the 2025 adopted county rate of $0.215500. A “no” vote does not freeze last year’s county rate; it caps the increase at the voter-approval figure.

Your full bill also includes city, school district, college, and special-district rates. Only the county slice was on Proposition A.

When are Dallas County property taxes due?

Pay by January 31, 2027 to avoid penalties. January 31, 2027 is a Sunday, so many Texas tax offices treat Monday, February 1, 2027 as the last day to pay without penalty. Confirm the date printed on your statement.

Taxes become delinquent on February 1 (or the next business day if the office rolls weekend deadlines). Escrow borrowers usually pay through their mortgage servicer; watch for an escrow analysis after the bill posts.

What you can still control: exemptions and a protest

Proposition A only set the county rate. It did not change your home’s appraised value at the Dallas Central Appraisal District (DCAD). Two levers still matter:

• Homestead and other exemptions on file with DCAD lower taxable value before rates apply. Confirm your account shows the exemptions you qualify for.
• A property tax protest challenges DCAD’s value before the Appraisal Review Board (ARB). A lower value cuts every rate on the bill—county, city, school, and the rest.

The next protest window for most owners is the spring notice cycle (typically by May 15 or 30 days after the notice, whichever is later). Confirm the deadline on your DCAD notice.
