On July 11, the Illinois Department of Revenue (Department) finalized proposed regulations related to the legislative changes affecting Illinois qualified investment partnerships (QIPs) enacted in 2023. (Section 100.9730 Investment Partnerships and Section 100.7034 Investment Partnership Withholding). Since the first Notice of Proposed Rulemaking was published in December 2023, the Department has sought public comments to address this complex issue.
Due to these legislative changes, which are effective for tax years ending on or after December 31, 2023, the definition of which partnerships qualify as Illinois QIPs was expanded to capture most non-operating partnerships that are treated as securities under 15 U.S.C. 77b(a)(1); however, this expanded QIP definition comes with a great deal of added complexity. The final regulations provide additional guidance and several examples to assist taxpayers in navigating these changes.
Taxpayers who may be affected by these changes should examine the potential impact of the new QIP withholding tax regime, including the impact of it being considered an entity-level tax. In addition, there are new considerations for the reporting of income and the filing requirements for the partnership and its partners.
In 2023, Illinois enacted S.B. 1963, which made several changes that affect investment partnerships, effective for tax years ending on or after December 31, 2023. S.B. 1963 amended the definitions of “investment partnership” and “qualifying investment securities’,” thereby expanding both the asset and income tests. The 90% asset test now includes partnerships as a qualifying security, and the 90% income test now includes partnership income from lower-tier partnership interests as qualifying income. The legislation also now requires QIPs to report and withhold Illinois-sourced income on nonresidents, including at an increased 4.95% (up from 1.5% for non-QIP withholding) QIP withholding tax rate on the QIP’s partnership partners. See our prior Insight for additional details relating to this legislative enactment.
Over the past several months, the Department released filing instructions detailing the impact of the changes as well as proposed regulations with commentary, providing additional guidance relating to these legislative changes.
On July 11, the Department adopted as final the draft regulations in whole, including the addition of Example 8 that had been added in April after the original release of the draft regulations. The final regulations in general provide guidance on the complex filing requirements of QIPs and tiered partnership structures, although questions remain about certain scenarios.
The following highlights a few of the areas that may warrant additional consideration given the changes and clarifications made by the final regulations:
