Changes to Ohio Commercial Activity Tax in 2024

Effective January 1, 2024, the Ohio Commercial Activity Tax (CAT) will undergo major changes following the enactment of Am. Sub. H.B. 33 of the 135th Ohio General Assembly

For tax periods beginning on and after January 1, 2024, the CAT annual minimum tax is eliminated, and the exclusion amount is increased from $1 million to $3 million. Therefore, taxpayers with taxable gross receipts of $3 million or less per calendar year will no longer be subject to the CAT. 

The Ohio Department of Taxation has advised both annual and quarterly taxpayers who anticipate having less than $3 million in taxable gross receipts in tax year 2024 to cancel their CAT account immediately and use an effective date of December 31, 2023. 

Taxpayers can visit the Ohio Business Gatewayand select the CAT Cancel Account transaction, to cancel your CAT account.  Alternatively, taxpayers may check the cancellation check box when filing their last return.  If unable to cancel using either of these methods, taxpayers may submit a Business Account Update Formto cancel the account.
