A corporation is subject to Maine income tax if it has nexus with Maine and has income properly apportionable to Maine pursuant to Title 36 M.R.S., chapter 821, regardless of whether it is authorized to do business in this State. A corporation has nexus with Maine if it engages in the activities listed in section .03 below or meets the criteria of 36 M.R.S. §5200-B and section .04 below of this rule. However, a corporation's activities will not subject it to the income tax jurisdiction of Maine if the constitution or laws of the United States, including 15 United States Code § 381et seq. (P.L. 86-272), preclude the exercise of jurisdiction.
