To vote in Connecticut, you must be a U.S. citizen, at least 18 by Election Day, and a resident of the town where you register. The state’s voting requirements let you sign up online, by mail, in person at your registrar’s office or the DMV, or on the spot during early voting and Election Day. Most voters can satisfy the ID rule with something as ordinary as a Social Security card or a pre-printed card showing their name and address, and anyone without ID can still cast a regular ballot by signing a sworn statement at the polls.
Who Qualifies to Vote
Three rules decide eligibility. You must be a U.S. citizen, you must live in the Connecticut town where you apply, and you must be 18 or older by the date of the election. Residency is physical: your dwelling has to sit within that town’s boundaries.1Justia Law. Connecticut Code 9-12 – Who May Be Admitted as Electors
If your 18th birthday falls on or before Election Day, you can apply ahead of time and your registration takes effect on your birthday. Seventeen-year-olds who will turn 18 by the next Election Day are also eligible to begin the registration process.2CT.gov. Voting Eligibility
How to Register and When
You have three ways to get on the rolls.
- Online, through Connecticut’s voter registration system. The system pulls your signature from DMV records, so you need a current Connecticut driver’s license, learner’s permit, or non-driver photo ID with a signature already on file.
- By mail, using Form ED-671. Print the form, complete it, and send it to the registrar of voters in your town.3CT.gov. Mail-In Voter Registration Form ED-671
- In person, at your town’s registrar of voters office or while doing business at the DMV. Public assistance and disability offices also offer registration.
First-time mail registrants have an added step. You need to supply a Connecticut motor vehicle license number, the last four digits of your Social Security number, or a copy of a photo ID, utility bill, or bank statement showing your name and address. Skipping this flags your record and affects what ID you bring to the polls later.4FindLaw. Connecticut Code 9-23r – Mail-In Voter Registration Identification
The mail-in deadline is 18 days before an election or primary. Miss that window and you can still vote through Same-Day Registration during early voting or on Election Day.5CT.gov. Same Day Registration
Same-Day Registration does not happen at your regular polling place. Each town designates a separate SDR location, open from 6 a.m. to 8 p.m. on Election Day and during early voting hours. Bring proof of identity and residency. If you are in line when polls close, stay in line; you can finish registering and vote. SDR is open to anyone eligible who either is not registered anywhere in the state or has moved to a new town.5CT.gov. Same Day Registration
What to Bring to the Polls
Connecticut’s ID rule has two tiers, and most voters fall into the easier one.
Most Registered Voters
You can show your Social Security card or any pre-printed form of ID that displays your name along with at least one of three things: your address, your signature, or your photograph. A library card with your name and address qualifies.6Justia Law. Connecticut Code 9-261 – Process of Voting
First-Time Mail Registrants
If you registered by mail for the first time on or after January 1, 2003, and did not supply adequate identification then, your name is flagged on the registry. At the polls you need a current, valid photo ID with your name and address, or a copy of a recent utility bill, bank statement, government check, paycheck, or other government document showing your name and address.6Justia Law. Connecticut Code 9-261 – Process of Voting
No ID at All
You will not be turned away. Sign Form ED-681 under penalty of false statement, swearing you are the person listed on the rolls, and you can cast a regular ballot. A false statement on that form is a class A misdemeanor, carrying up to one year in prison, a fine up to $2,000, or both.7Justia Law. Connecticut Code 53a-157b – False Statement
Early Voting and Absentee Ballots
Connecticut rolled out in-person early voting in 2024 under Public Act 23-5. General elections have a 14-day early voting window that begins 15 days before Election Day and ends 2 days before. Primaries have a shorter window of about 7 days. Early voting happens at designated locations in your town, and Same-Day Registration is available at those sites during that period.
Absentee voting is narrower. Connecticut does not offer no-excuse absentee ballots. You qualify only if one of these applies:8CT.gov. Absentee Voting
- You will be away from your town during all voting hours on Election Day.
- Illness or physical disability prevents you from going to your polling place, including when you are caring for someone who is ill or disabled.
- You are an active member of the armed forces.
- Your religious beliefs forbid secular activity on Election Day.
- You will be serving as an election official at a polling place other than your own during all voting hours.
If your reason was simply a scheduling conflict, the 14-day early voting window now covers that situation in person.
Voting After a Felony Conviction
A felony conviction combined with confinement in a correctional institution causes you to lose voting rights in Connecticut. Placement in a community residence alone does not.9Justia Law. Connecticut Code 9-46 – Forfeiture of Electoral Privileges
Your rights are restored once you are released from confinement. You do not have to finish parole or probation first. If you were registered in a Connecticut town before your conviction and return there, your privileges come back automatically. If you move to a different town or were never registered, you can register by showing proof of release.10Justia Law. Connecticut Code 9-46a – Restoration or Granting of Electoral Privileges
One narrow exception: if the felony involved violating Connecticut’s election laws under Title 9, you cannot register until you have completed both parole and probation for that offense. The Department of Correction issues a document certifying your release, which you present to your town registrar. People on probation, on parole, or living in a community residence are eligible to register and vote.11CT.gov. Restoration of Voter Rights
Military, Overseas, and Accessible Voting
Active-duty military, their spouses and dependents, Merchant Marine personnel, and U.S. citizens living abroad vote under the federal Uniformed and Overseas Citizens Absentee Voting Act. Connecticut must send these voters absentee ballots at least 45 days before any federal election. Registration and ballot requests use the Federal Post Card Application, and your last state of legal residence determines which Connecticut town handles your ballot.12Federal Voting Assistance Program. Uniformed and Overseas Citizens Absentee Voting Act
Every polling place in Connecticut must be physically accessible under Title II of the Americans with Disabilities Act. Towns can use temporary fixes such as portable ramps or door stops; when a barrier cannot be resolved, the town must move voting to an accessible site or provide an alternative voting method there. Voters who use wheelchairs or mobility devices, those with difficulty walking or using stairs, and those with vision loss all have the right to full and equal access to every part of the voting process.13ADA.gov.
