    You are not alone. The CAT is an annual tax imposed for the privilege of doing business in Ohio. The CAT is on taxable gross receipts from most business activities in Ohio. Most sales generated in the ordinary course of business are subject to the CAT. The CAT only applies to those gross receipts that are sitused (sourced) to Ohio. In other words, the sale is to another entity in Ohio.


    Who is Subject to the CAT?

    The CAT applies to most businesses including but not limited to the following:

    • Retail
    • Wholesale
    • Service
    • Manufacturing

    • Sole Proprietorships
    • Partnerships
