IRS eFile ERO Registration
Tax preparers are automatically registered with Ohio as an Electronic Return Originator (ERO) as long as they are registered and approved as an ERO by the IRS. The Ohio Department of Taxation does not require a copy of the IRS acceptance letter or the IRS 8633. Ohio's only requirement is that preparers use software that has been approved by Ohio.
