How do I amend my 2024 Indiana tax return to include the required Composite Schedule?

Due to a TurboTax error, some business returns did not include the required Composite Schedule on the Indiana Partnership/S-Corporation tax return. This is a state reporting requirement, and while there is no impact on the tax liability, Indiana assesses a $500 penalty when the Composite Schedule is not filed.

To correct your return, please follow the steps below:

  • Go to the TurboTax.com website and sign in to your account.

  • Print a copy of your Indiana business return, which will now include the completed Schedule Composite. 

  • Check the box to indicate it is an amended return. This will be on the first page of Form IT-20S/IT-65. No additional changes are needed to complete the amended return.

  •  Mail your return to the following address:

    INDIANA DEPARTMENT OF REVENUE
    PO BOX 7147
    INDIANAPOLIS, IN 46207-7147

  • Sign and date the return and attach a separate cover sheet to your amended Indiana return with the following explanation written on it:TO INCLUDE SCHEDULE COMPOSITE”.

  • Keep a copy of the amended return for your records.

  • NOTE: The composite schedule must be filed or the Indiana Department of Revenue will assess a $500 penalty.

  • If you have already had the penalty assessed, please reach out to Audit Defense for assistance.
