What Is the Ohio Commercial Activity Tax (CAT)?

The CAT is a privilege tax imposed on businesses for the right to do business in Ohio. It is calculated based on a business's gross receipts from activities conducted within the state, rather than on profits. The tax rate is set at 0.26% for taxable gross receipts exceeding $6 million per year. Businesses with gross receipts of $6 million or less are exempt from the CAT starting in 2025.

Effective January 1, 2025, the annual exclusion amount for the CAT has increased from $3 million to $6 million. This means that businesses with taxable gross receipts of $6 million or less in a calendar year are no longer required to file or pay the CAT. (nfib.com)
