Illinois addresses combined apportionment for unitary groups with members that apportion their income differently. In proposed rules, the Department of Revenue addresses 2017 legislation that permits unitary groups to include members that use different apportionment formulas.
Industry Specific Apportionment Rules Still Used
The new apportionment formula, in effect as of January 1, 2018, begins with subrgroups of members that use the same industry specific apportionment formula apportioning income as though they are a separate unitary group. The Department of Revenue’s regulation provides an example of a unitary business group with sales members, insurance company members, and transportation members. The example illustrates how the proposed apportionment changes work.
Industry Specific Apportionment Still Followed
Comments on the proposed rules must be submitted no later than 45 days after their publication date in the register. The proposed rule is printed in the Illinois Register, as well as the address to submit comments.
