In plain language

This bill updates rules for combined reporting in Illinois income tax.

The bill modifies provisions of the Illinois Income Tax Act regarding unitary business groups and foreign persons. It specifies which members are included in combined reporting and updates liability rules.

  • Workers: Changes to tax reporting may influence job security and operations within affected businesses, potentially impacting workers.
  • Small Business: Small businesses will need to understand the new criteria for unitary business group membership to comply with tax reporting.
