The last day to register to vote in Texas is 30 days before each election, and the exact date changes depending on which election you mean.

Here are the key 2026 deadlines people are asking about most:

  • For the March 3, 2026 statewide primary election, your registration application must be received or postmarked by Monday, February 2, 2026.
  • For the May 26, 2026 local election date listed in the state’s 2026 calendar, the last day to register is Monday, April 27, 2026.
  • For the November 3, 2026 general election, the last day to register is Monday, October 5, 2026.

In general, Texas law sets the registration deadline at 30 days before Election Day, whether you register in person or by mail (mailed forms must be postmarked by that 30‑day mark).

If you’re unsure which election you care about, a safe rule is: look up the Election Day, then count back 30 days and make sure your application is in the mail (or at the registrar’s office) no later than that date.
