Proposition 2 1/2 is the title given to an initiative petition adopted by the voters of the Commonwealth of Massachusetts in 1980.
Its primary features relate to the total amount of property taxes a city or town can raise each year. Other parts of the initiative limit state agency assessments on cities and towns, prohibit unfunded state mandates, and repealed binding arbitration for certain public employees. In addition, it reduced the motor vehicle excise tax rate and has allowed renters a deduction on their state income tax.
The levy limit provisions of Proposition 2 1/2 affect the total amount of taxes to be raised by a city or town. It does not apply to an individual tax bill.
