An Act relative to historic building tax credits

This bill creates a 50% tax credit for owners of qualified historic buildings in Massachusetts who install fire sprinkler systems. It directly affects property owners (including individuals, businesses, and entities) who maintain historic structures, covering up to $10,000 in annual installation costs. The credit can be carried forward for up to five years if it exceeds the current year's tax liability, but cannot reduce taxes below zero. The credit applies to costs incurred through 2035 and is subject to regulations set by the Massachusetts Fire Prevention Board.
