A law that took effect in October 2023 changed the deadline for mailed absentee ballot requests. Mailed requests must be received by noon the day before an election, not 5 p.m.

A 2023 law requires voters who register for the first time on Election Day to mail their ID within seven days of registering if they do not show their ID at the polls. These voters will receive affidavit ballots that will be counted on Election Day but will be removed if ID is not received by the deadline.

Redistricting in 2022 redrew the boundaries of certain state legislative and U.S. congressional districts. Some state legislative district boundaries are being challenged in court. Check back for updates.

• By mail: Registration by mail is available if you have an approved reason for not doing so in person, such as a religious observance or disability. If you qualify, call your city or town clerk to request a voter registration form. Include a copy of your driver’s license or other valid form of ID when returning your application. You will need a witness to sign your absentee-voter registration affidavit. Check with your city or town clerk for local deadlines.
  
• In person: Fill out a voter registration form at your city or town clerk’s office. You’ll need to show various forms of ID proving your name, age, citizenship status and where you live, such as a driver’s license and U.S. passport. A full list of acceptable IDs is available on the secretary of state’s website. You can also register to vote at your polling place on Election Day.
  
• Online: New Hampshire offers online voter registration if a disability, such as blindness, prevents you from filling out a form by hand. Call your city or town clerk to request an accessible online absentee registration form and for information about local deadlines. 

Registration deadlines before the election vary by community and will be somewhere between six and 13 days before Election Day. Check with your city or town clerk for local deadlines. But regardless of where you live, you’ll be able to register at your polling place on Election Day.

Yes. You can only vote in the primary of the party with which you are registered. If you’re an undeclared voter, you can choose to vote in the Democratic or Republican primary, but not both. After the election, you’ll remain a registered member of that party unless you fill out a request to return to undeclared status, which you can do before leaving your polling place. Note that the deadline to change your party affiliation before the presidential primary has passed.

You can vote absentee only for approved reasons, such as a disability or work commitment.

• By mail: Print an application from the secretary of state’s website, then complete and mail it to your city or town clerk’s office. You can also call your city or town clerk to request a mailed application. Absentee ballot requests must be received by noon the day before an election, but you’re encouraged to apply as soon as possible.

• In person: Go to your city or town clerk’s office to apply for a ballot, or print an application from the secretary of state’s website and bring it with you. You can request a mail ballot until 5 p.m. the day before an election.

• Online: Only voters who are unable to fill out a printed form due to a disability, such as blindness, may request an accessible absentee ballot online. If you qualify, you may receive and mark the ballot electronically and may return it to your city or town clerk by mail, in person or by using a delivery agent. Contact your city or town clerk for more information.

Absentee ballot requests are due by 5 p.m. the day before an election. But you’re encouraged to apply as soon as possible, especially if you are submitting your request by mail.

Place your completed ballot in the inner envelope and sign the affidavit on the outside. If you have a disability and received assistance, the person who helped you must sign an acknowledgment that appears on the absentee-ballot application and on the affidavit. Seal the inner envelope before placing it in the outer mailing envelope. If you’re including absentee-voter registration forms and proof that you qualify, place those documents in the outer envelope before you seal it.

• By mail: Send your ballot to your city or town clerk with proper postage. It must be received by 5 p.m. on Election Day.

• In person: Hand-deliver your ballot to your city or town clerk by 5 p.m. the day before an election. On Election Day, absentee ballots will be accepted only by mail or from a delivery agent, such as an immediate family member, until 5 p.m. Your delivery agent may be asked to show ID and fill out paperwork to deliver your ballot.

Track your absentee ballot through the state’s voter information portal.

If you qualify for an absentee ballot, you can cast an in-person absentee ballot at your city or town clerk’s office.

Polls are open between 11 a.m. and 7 p.m., but extended hours vary by location. Check your polling place or contact your city or town clerk for exact hours.

You may cast a ballot as long as you are in line before polls close.

You’ll need an acceptable form of photo ID, such as a driver’s license or U.S. passport, to vote on Election Day. The secretary of state’s website has a full list of acceptable forms of ID. If you don’t have one with you, you can sign an affidavit, have your photo taken and proceed to vote.
