This proposed constitutional amendment would require Massachusetts income tax rates to be graduated, in order to distribute the burden of tax fairly and equitably. The proposed amendment would require the rates for taxpayers in higher income brackets to be higher than the rates for taxpayers in lower income brackets. The proposed amendment would also allow the state Legislature to grant reasonable exemptions and abatements and establish the number and range of tax brackets. The proposed amendment would eliminate from the Massachusetts Constitution the present requirement that income taxes must be levied at a uniform rate throughout the state upon incomes derived from the same class of property.
