Voting by mail

All registered voters in New York state are now eligible to apply for an early mail ballot. The New York Early Mail Voter Act requires registered voters to obtain early mail voting ballots through an application to the board of elections.

There are several ways to apply for the early voting ballot: Use the online Ballot Request Application portal, go in person to your local county board of elections, or allow another person to deliver the application in person to your local county board of elections. Voters with a print disability should apply by using the online Accessible Ballot Application.

Certain New Yorkers are eligible to apply for an absentee ballot. The form to apply is different, but the places to apply are the same as listed above for early mail ballots, and the ballot can be returned using the same methods as early mail voters.

A New York City resident is eligible for an absentee ballot if they are:

• absent from New York City on Election Day
• unable to go to the polls due to illness or disablity, or because they are the primary caregiver of someone who is ill or physically disabled
• a resident or patient at a VA hospital
• In jail or prison for any reason, unless they were convicted of a felony

Early mail or absentee ballots can be returned by mail; by dropping them off at early voting poll sites any day those sites are open; by dropping them off at your county Board of Elections office; or by dropping them off at an Election Day poll site on Election Day.

Voters are not able to cast a ballot with a voting machine if they were issued an early mail or absentee ballot. Anyone who requested an early mail or absentee ballot but wants to vote in person will have to fill out an affidavit ballot.
