An Act establishing a municipal tax assessment increase limit

This bill allows Massachusetts cities and towns to vote on whether to cap the annual increase in property taxes for primary residences. If approved by a majority of voters, the local government can limit these tax hikes to the lower of 3 percent or the official inflation rate, while setting a separate 10 percent cap for non-primary homes. The law ensures that these limits do not apply to tax increases caused by property improvements or when a home is sold, and it requires homeowners to notify local officials within 30 days if they move out of their principal residence.
