Ohio Department of Taxation Online Services - eForms

Welcome to Ohio eForms - Registration

A single one-time eForms registration allows a business taxpayer to register and file for the commercial activity tax (CAT) annual return and minimum tax payment return and/or sales and use tax (SUT) returns. The taxpayer can also designate an authorized person to file returns on their behalf. This person must also register only once before filing. Taxpayers and authorized filers also have the option of updating their information when necessary.

Registration and account services

Prior to filing, all taxpayers and authorized filers/tax practitioners must complete an eForms registration. A single registration allows taxpayers and authorized filers/tax practitioners to file the CAT annual return and minimum tax payment return and/or SUT returns. Choose from one of the following registration options below.

Registration:

• Business taxpayers - If you plan to file returns for your business(es), this registration option is probably for you. There's also a tutorial to help you get started (note: this tutorial contains audio). (PLEASE NOTE: Taxpayers who want to have others file on their behalf must authorize an authorized filer/tax practitioner when they register as individual users).
• Authorized filers/tax practitioners - If you are an internal employee or third party tax professional who would like to file returns on behalf of the taxpayer(s), this registration option may be for you. (PLEASE NOTE: Taxpayers must add you as an authorized filer ID when they register as individual users. This enables you to file for multiple taxpayers with a single sign-on.)
