Springfield, Illinois. The Illinois Department of Revenue on July 10 published proposed amendments to multiple local tax rules, consolidating sourcing provisions for Home Rule Municipal Service Occupation Tax, Regional Transportation Authority Service Occupation Tax, and Home Rule Municipal Retailers' Occupation Tax; the rules implement statutory changes from Public Act 104-0006 and identify affected categories such as servicepersons, marketplace facilitators, and marketplace servicepersons. The proposals, filed in the Illinois Register as Proposed Reg.
