How Corporate Excise tax is calculated

Learn the steps and rules when calculating corporate excise tax.


Massachusetts corporate excise tax is calculated by adding two different measures of tax depending on whether the corporation is a tangible or an intangible property:

  • A net income measure and
  • Either a property measure or a net worth measure

The income measure is calculated at a rate of 8% of the corporation's taxable net income apportioned to the Commonwealth.

The property measure is imposed at a rate of $2.60 per $1,000 of either a corporation's taxable Massachusetts tangible property or its taxable net worth.

A corporation's total excise is the combination of the property measures and net income measures, or the minimum corporate excise, whichever is greater.
