36 M.R.S. § 4104 — Tax on estate of nonresident

A tax is imposed on the Maine taxable estate of every person who, at the time of death, was a nonresident. The amount of tax equals the tax computed under section 4103 , as if the nonresident were a resident, multiplied by the ratio of the value of that portion of the decedent's adjusted federal gross estate that consists of real and tangible personal property located in this State to the value of the decedent's adjusted federal gross estate.
When real or tangible personal property is owned by a pass-through entity, the entity must be disregarded and the property must be treated as personally owned by the decedent if the entity does not actively carry on a business for the purpose of profit and gain; the ownership of the property in the entity was not for a valid business purpose; or the property was acquired by other than a bona fide sale for full and adequate consideration and the decedent retained a power with respect to or interest in the property that would bring the real or tangible personal property located in this State within the decedent's adjusted federal gross estate.
