An Act relative to restoring corporate tax rates

This bill amends Massachusetts corporate tax laws to increase the state excise tax rate from 9.0% to 10.5% for tax years starting on or after January 1, 2023. The legislation directly affects corporations subject to the state excise tax by raising the rate on their taxable net income. Additionally, the bill adjusts the corresponding income tax rate for corporations from 8.0% to 9.5% effective the same date. These changes reverse previous reductions in tax rates that were in place since 2012.
