Composite Returns: Individual Liability

Section 100 Section 100.5120  Composite Returns: Individual Liability Notwithstanding the assumption of liability by the authorized agent, the persons included in a composite return will continue to remain liable for any unpaid liability attributable to them in their separate capacities.  The filing of a composite return will be considered as a group of separate returns which will meet the individual filing requirements of the Illinois Income Tax Act.  Persons not included in composite returns are required to meet their Illinois filing and payment obligations separately, and failure to do so could mean the imposition of civil and criminal penalties.
