The Minnesota Supreme Court respected a foreign entity’s federal check-the-box election for the purpose of determining which entities were included in the Minnesota combined franchise tax reports. The court held that including the income and apportionment factors of a foreign entity that elects under federal tax law to be disregarded as a separate entity did not violate Minnesota’s water’s edge rule. The court determined that the federal treatment as a disregarded entity also meant that it was disregarded for Minnesota franchise tax purposes, and it was therefore treated as part of its domestic parent.
