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 corporation:
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.
