Tax Classification Amendment is approved.

By a 2 to 1 margin, Massachusetts voters approve a binding referendum question that amends the state constitution to allow different tax rates for different kinds of property. Without classification, according to the Massachusetts Municipal Association, implementation of the new 100% valuation requirement would have resulted in Boston a 15% increase in residential property taxes and commercial and industrial taxes decreasing by 19% and 30% respectively. The new 100% valuation with tax classification becomes effective on January 1, 1979. The state limits the commercial tax rate to 175% of the residential rate in 1988,
