Schedule IN-OCC, also known as the Indiana “Other Certified Credits” schedule, is a form issued by the Indiana Department of Revenue. It is used by taxpayers to report and claim specific nonrefundable tax credits on their Indiana state tax return. These credits include various economic development incentives, housing-related credits, and investment credits offered by the state to encourage business and individual activities that align with Indiana’s development goals.
The form is divided into two parts:
- Part A: Used to report and claim certified credits that you are entitled to for the current tax year.
- Part B: Used to report carryforward credits — credits from previous years or unused credits from the current tax year that can be applied in future years.
Examples of credits that can be claimed using Schedule IN-OCC include the Affordable and Workforce Housing Credit, Hoosier Business Investment Credit, Film and Media Production Credit, Historic Rehabilitation Credit, and many others. The form is essential for ensuring that taxpayers claim their eligible credits accurately and in compliance with Indiana tax laws.
