Document:
If you moved to Massachusetts from another state, you must register to vote in Massachusetts to be able to vote. The last day to register in time to vote in the next election is by 8 p.m. twenty days before the election.
If you moved from out of state, you may register to vote the same day you become a resident of Massachusetts. And, under federal law, if you move within 30 days of a presidential election, you are allowed to vote for President and Vice President in your former state of residence, either in person or by absentee ballot.
If you moved within the state since you last voted, you should contact your local election office to determine whether your registration is current and to find out the location of your current polling place. Election officials may have changed your registration records to reflect your new address even if you did not notify the election official about the move. If your registration information has been changed to your current address, you should go to the polling place associated with that address to vote.
Many registered Massachusetts voters who move are still entitled to cast a ballot that will be counted — even if they did not notify the appropriate election official about the move before Election Day.
If you moved to a new address that is in a different polling place within the same city or town, you can vote in the polling place associated with your old address.
If you moved to a new address that is in a different city or town in the state, you can vote at the polling place associated with your old address for national and state officers for six months after the date on which you moved.
