Commercial Activity Tax (CAT): Table of Contents
The commercial activity tax (CAT) is an annual tax imposed on the privilege of doing business in Ohio, measured by gross receipts from business activities in Ohio. Businesses with Ohio taxable gross receipts of $150,000 or more per calendar year must register for the CAT, file all the applicable returns, and make all corresponding payments. A variety of resources on the CAT may be found below.
About the CAT
Taxpayers who are not registered for the CAT must register first before filing any return. If a person is unsure of how to register, it is advisable to register as a combined taxpayer group, as any election to consolidate is binding for eight calendar quarters. Requests to change registration status should be made by submitting the form CAT ES.
Taxpayers with taxable gross receipts in excess of $1 million are required to file and pay on a quarterly basis and to make the annual minimum tax payment. Other taxpayers file annually and pay the annual minimum tax.

Dealer in Intangibles
Am. Sub. H.B. 510 enacted by the 129th General Assembly in December 2012 repealed the dealer in intangibles tax by providing that the tax is in effect only for tax years prior to 2014. Depending on the taxpayer’s Ohio business activity, in 2014 a taxpayer will be responsible for filing either a financial institution tax return or a commercial activity tax return instead of the dealer in intangibles tax return. Taxpayers with dealer in intangibles tax liability for years prior to 2014 that have not filed all required returns should still file those returns with the Department.
