What is a Combined Taxpayer?

A group of entities, having more than 50% owned or controlled by a common owner, that chooses not to be a consolidated elected taxpayer must register as a combined taxpayer. A major difference between a consolidated elected taxpayer and a combined taxpayer is that a combined taxpayer only has to register all members that have the required contacts (nexus) to be required to be a taxpayer for this tax in Ohio.

Cautionary note: A combined taxpayer cannot exclude taxable gross receipts between its members nor exclude taxable gross receipts from others that are not members. A consolidated election must be made to obtain that exclusion. In addition, if the 80% common ownership test or election to exclude all entities that are not incorporated or formed under the laws of a state or of the United States election is made under the consolidated provision, such taxpayers with more than 50% ownership that have the requisite contacts (nexus) are required to register as a combined taxpayer or single entity taxpayer.

Similar to a consolidated elected taxpayer, a combined taxpayer must register, file returns, and pay the CAT as a single taxpayer.
