According to the New York City Charter, the role of the Voter Assistance Commission (VAC) is to encourage and facilitate voter registration and voting by all eligible United States citizens residing in New York City. VAC is strictly nonpartisan, and does not promote any candidate for elected office, political party, or political agenda.

VAC's mission is to increase participation in the democratic process. To achieve this goal, VAC monitors voter registration and voting in New York City. VAC also works with Mayoral agencies, private groups and individuals, and community-based organizations to promote voter registration and voter participation. VAC is comprised of 16 Commissioners and its day-to-day operations are managed by the Coordinator.
