A State-by-State Guide to Voter Registration Deadlines

Voting in an election can seem intimidating whether you’re a seasoned voter or a first-timer — and that feeling has only been heightened in the time of COVID-19. However, registering to vote is actually much easier than you think!

There are deadlines to be aware of if you want to be sure your vote is counted. In particular, if you haven’t registered to vote yet, it’s important to know when voter registration ends in your state so that you can register on time and rest easy knowing that you are successfully on the road to completing your civic duty. Here’s a useful guide to voter registration deadlines by state that you’ll want to mark on your calendar ASAP.

Note: be sure to check here for information regarding voting and COVID-19. You can request an absentee ballot if you are not comfortable heading to the polls in person, or if your plans change and you will not be in the state you registered to vote in on Election Day. Keep in mind that the deadlines for absentee ballots to be received by the states are different than the deadlines for registering to vote in general. Do your research as you register, and you will have no issues!
