Ohio Corporate Activity Tax Threshold Update


A significant change to Ohio’s Corporate Activity Tax (CAT) took effect on January 1st. The CAT, which was implemented in 2005, has had a minimum filing threshold of $150,000.00 in taxable gross receipts since its inception. As of 2024, the filing threshold has increased to three million dollars and will double in 2025 to a threshold of six million dollars.

If you are a current Ohio CAT filer and will no longer meet the new threshold requirements for 2024, you may cancel your account with an effective date of December 31, 2023.

Please contact Thompson Tax for any questions you may have regarding this change. We are happy to discuss your options and can assist with final return filing and account closure if you do not meet the 2024 threshold.
