Kansas primary election: Early voting dates, mail ballot deadline change & more

The Kansas primary election isn’t until Aug. 4, but you may be able to cast your vote now.

Depending on where you live and your party affiliation, your ballot may include a variety of local, state and federal races, along with a constitutional amendment that will determine if Kansans elect state supreme court justices or if the current nominating commission system remains.

Some of the most hotly contested races include partisan primaries for governor and seats in the U.S. Senate and House of Representatives.

Before you head to the polls or mail in your ballot, here’s what you should know about the Kansas primary election.

Advance voting in Kansas

The first day of advance voting in Kansas is July 15, but not all counties start accepting voters this early.

In Sedgwick County, for example, advance voting starts July 20 (and voting at most satellite locations doesn’t start until July 28).

Early voting in all 105 counties must start by July 28. To find the specific times and early voting locations for your county, check with your county election office.

Voting by mail in Kansas

To vote by mail in the Sunflower State, you must apply for an advance ballot. The application is available at the Kansas Secretary of State website.

The state will mail advanced ballots to voters who requested them on July 15.

All mail ballots must be received by 7 p.m. on Election Day to be counted. This is a change to previous years, which allowed a grace period, following a law passed by the Kansas Legislature in 2025.

“Voters will no longer have a 3-day grace period for their ballot to arrive,” according to the website of Secretary of State Scott Schwab.

Voters with mail ballots may also drop them off at their county election office or another polling place in their county.

To check on the status of your mail ballot, call your local election office or visit kansasvoterinfo.gov.

Previewing your ballot

To better prepare yourself for voting at the polls, you may preview your ballot at Kansas Voter View.

You’ll be asked to provide your first name, last name and date of birth. Then, under sample ballots, you can click on a preview of your primary election ballot.

Alternatively, a statewide list of candidates can be found at the Kansas Secretary of State website. Kansas counties, including Sedgwick County, also provide a list of offices and candidates running for election.

Registering to vote

While it is too late to register to vote for the primary election, you have until Tuesday, Oct. 13, to register to vote in the general election.

To register to vote in Kansas, you must be a U.S. citizen, a resident of the state and at least 18 years old by election day.

You may register to vote online at votekansas.gov, or by sending in a completed paper form that is postmarked before the deadline.
