Ohio Department of Taxation Online Services - eForms

Welcome to Ohio eForms - Commercial Activity Tax

Ohio now offers a new way to electronically file the annual return and minimum tax payment of the commercial activity tax (CAT): eForms.

eForms are Adobe Acrobat PDF versions of some of Ohio's key tax forms, and this format is now available for CAT 2008 annual return and 2009 minimum tax payment return filers only. The CAT eForm can be completed electronically, much as one would do with pen and paper. (Adobe Reader 9.1 or greater is required; download the latest version of Adobe Reader at www.adobe.com.)

When complete, returns can be submitted to the Department of Taxation with the click of a button, or saved to the taxpayer's computer. Payment options are credit card, electronic check, paper check and ACH credit.

Taxpayers and authorized filers/practitioners who have used eForms to file sales tax returns can get started with their CAT annual return simply by adding a CAT account to their existing registration. New users, though, will need to register first. All users may benefit from the other resources available below.

Registration, account and payment information

• Registration and account services - Taxpayers who want to register their tax account(s), make changes to their existing registration or recover a lost password should choose this option. There's also a tutorial to help you get started (note: this tutorial contains audio).
• Payment options - eForms includes several payment options. Click here to review the payment options first, before choosing an option within the eForm.

CAT eForms available

If you've already updated your eForms registration to include your CAT account, go ahead and get started. Choose the return form below, download and save it to your computer, and begin filing. Payment options are provided at the end of the form. Please note that this form is for electronic filing only.

If you need help, there's a tutorial available to assist you (note: this tutorial contains audio).

If you have Internet Explorer 8.0 on your computer, please make sure that you are using the latest version of Adobe Reader.
