This guide provides detailed information on who must file, how to file, payment methods, available exemptions, and important due dates.

The Ohio Commercial Activity Tax (CAT) is a tax imposed on the gross receipts of businesses operating within the state. Introduced in 2005, the CAT replaced the Ohio Corporate Franchise Tax for most businesses. It is a broad-based tax designed to apply to a wide range of business activities, ensuring that all businesses contribute to the state’s revenue.

Any business with taxable gross receipts of over $150,000 per calendar year is required to file the Ohio Commercial Activity Tax. This includes sole proprietorships, partnerships, corporations, and other business entities operating in Ohio. Businesses below this threshold are not required to register or pay the CAT. Understanding whether your business meets the filing threshold is crucial for compliance with Ohio’s commercial activity tax regulations.

How to File Ohio Commercial Activity Tax?

Filing the Ohio Commercial Activity Tax involves submitting specific forms and adhering to state guidelines. Businesses must file Form CAT 1, the Registration Application for Commercial Activity Tax, to register with the Ohio Department of Taxation. Once registered, businesses file Form CAT 12, the Annual Commercial Activity Tax Return, and Form CAT 1/10 for quarterly filings if their taxable gross receipts exceed $1 million annually. The Ohio Business Gateway provides an online platform for filing these forms, ensuring a streamlined and efficient process. Alternatively, businesses can file by mail, sending the completed forms to the designated address.

The primary forms used for filing the Ohio Commercial Activity Tax are Form CAT 1 for registration, Form CAT 12 for annual returns, and Form CAT 1/10 for quarterly filings.

Accurate completion of these forms is essential to ensure proper filing and compliance.
