Schedule IN-OCC is used to claim certified credits. To claim these credits, you typically need to apply and be approved. Once you're approved, you'd receive a letter from the state that lists your certification or project number. Enter the certification or project number with no spaces or dashes.
If none of the credits on the schedule apply to you, you can delete the schedule so that you can complete your return.
