Schedule Composite-COR, issued by the Indiana Department of Revenue, is a tax form designed for corporate entities to report and pay Indiana adjusted gross income tax on behalf of their non-resident corporate shareholders or partners. This form is commonly used by partnerships, S corporations, and trusts or estates that distribute income to corporate entities residing outside of Indiana. By filing Schedule Composite-COR, the filing entity ensures compliance with Indiana tax laws by consolidating the tax obligations of all non-resident corporate entities into one report. This process simplifies tax reporting for the non-resident corporations, as they are not required to file separate Indiana tax returns. The form also calculates the pro rata share of income, state tax, pass-through entity tax, and total tax liability for each non-resident corporate entity.
How to File Schedule Composite-COR?
To file Schedule Composite-COR correctly, follow these steps:
- Prepare the Entity’s Primary Tax Return: Complete the appropriate Indiana tax return for the entity (e.g., Form IT-65 for partnerships or Form IT-41 for trusts/estates). Data from Schedule Composite-COR will be summarized and carried over to these forms.
- Attach Schedule Composite-COR: Enclose the completed Schedule Composite-COR with the entity’s Form IT-65 or Form IT-41 when filing.
- Include Additional Sheets, If Necessary: If the number of non-resident corporate shareholders or partners exceeds the available space on the form, use additional copies of Schedule Composite-COR and carry over totals.
- File Electronically or by Mail: Submit the completed tax return and all attached schedules according to the Indiana Department of Revenue’s filing requirements.
