You have to be at least 18 years old on Election Day to vote for president of the United States. The 26th Amendment sets that floor for every state, and no state can push it higher.1Constitution Annotated. Twenty-Sixth Amendment Age is only part of the picture, though. You also need U.S. citizenship, residency in the state where you vote, and a voter registration on file before your state’s deadline.
The Deadline Is Your Birthday, Not the Campaign
The date that matters is the general election itself. Presidential elections fall on the first Tuesday after the first Monday in November every four years.2USAGov. Overview of the Presidential Election Process The next one is in November 2028. If you turn 18 on or before that Tuesday, you can vote. If your birthday falls the day after, you can’t, even by 24 hours.
That means you can spend the entire campaign season at 17 and still cast a ballot, as long as your 18th birthday arrives in time. Your eligibility is measured by your age when the polls open, not when you filled out any paperwork.
Registering and Voting Before You Turn 18
In almost every state, you can submit a voter registration application while still 17, provided you’ll be 18 by Election Day.3USAGov. Who Can and Cannot Vote Many states go further and let you pre-register even earlier. Roughly 18 states and D.C. allow pre-registration starting at age 16, several more allow it at 17, and Colorado lets residents pre-register at 15.4Vote.gov. Preparing to Vote: Age 18 and Under Your record sits in a pending status until your 18th birthday, then activates automatically. No follow-up paperwork.
Primaries are a separate question. More than 20 states and D.C. let 17-year-olds vote in primary elections or caucuses if they’ll turn 18 by the general election.3USAGov. Who Can and Cannot Vote This is a state-by-state policy, and rules can vary by party within the same state, especially where a party runs its own caucus rather than a state-administered primary. If you’re 17 and interested, check both your state’s rules and the specific party’s rules well ahead of the primary date.
Citizenship and Residency
Federal elections are limited to U.S. citizens, including citizens born abroad, citizens living overseas, and dual citizens.3USAGov. Who Can and Cannot Vote A non-citizen who votes in a federal election faces up to a year in prison under federal law, with additional immigration consequences on top.5Office of the Law Revision Counsel. 18 USC 611 – Voting by Aliens
You also need to meet your state’s residency rules, though federal law bars states from imposing long residency waiting periods for the presidential race specifically.6Office of the Law Revision Counsel. 52 US Code 10502 – Residence Requirements for Voting If you moved recently, you can generally still vote for president in either your new state or your old one, depending on timing and local rules. People without stable housing can also meet residency requirements in many jurisdictions using a shelter address or the intersection where they sleep.
Registration and Deadlines
Every state except North Dakota requires voter registration before you can cast a ballot.3USAGov. Who Can and Cannot Vote Deadlines vary. About half of states require you to register 20 to 30 days before the election. Roughly 19 states and D.C. allow same-day registration, so you can register and vote at the polls on Election Day itself. The rest sit somewhere in between. If you’re not sure, register as soon as you’re eligible.
Federal law also requires every state to offer voter registration through motor vehicle offices.7Office of the Law Revision Counsel. 52 USC 20504 – Simultaneous Application for Voter Registration and Application for Motor Vehicle Drivers License Applying for or renewing a driver’s license doubles as a voter registration application unless you opt out. For a teenager getting a first license, this is often the simplest way to be registered and ready the day you turn 18.
What ID You Need to Register
Your registration application for a federal election must include either your driver’s license number, if you have a current valid license, or the last four digits of your Social Security number. If you have neither, the state assigns you a unique identifier for voter registration purposes.8Office of the Law Revision Counsel. 52 USC 21083 – Computerized Statewide Voter Registration List Requirements That’s the federal baseline. States can layer on additional ID requirements when you actually show up to vote, so check what your polling place will ask for.
When Voting Rights Can Be Lost
Meeting the age, citizenship, and registration requirements doesn’t lock in permanent eligibility. A felony conviction is the most common way people lose the right to vote, and the rules for restoration depend entirely on the state. In some jurisdictions, incarcerated people never lose the right at all. In roughly half of states, voting rights are restored automatically after release from prison. Others require you to finish parole and probation, and some ask you to pay outstanding fines or restitution first. A smaller group of states strip voting rights indefinitely for certain offenses, requiring a governor’s pardon or a separate petition.
Some states also restrict voting for people placed under a court-ordered guardianship after a finding of mental incapacity. Standards vary. Some states remove voting rights automatically when a guardianship is established; others evaluate capacity to vote case by case. If you or a family member is going through a guardianship proceeding, ask the court directly about voting rights, because they don’t always come up on their own.
