A federal district court just struck down an IRS rule that had been closing the door on a pretty compelling tax savings opportunity available to your clients today, the Section 48E Clean Electricity Investment Tax Credit. The ruling, handed down on June 6, 2026, reinstated a key pathway that allows investors to lock in credit eligibility for large-scale wind and solar projects a pathway the IRS had tried to eliminate just last year. The window is not wide open. July 4, 2026 is still the critical deadline, and the government will almost certainly appeal. But for advisors who act quickly, this ruling creates a genuine, time-sensitive planning opportunity. Here is what you need to understand, and what you should be doing right now.

State Tax Planning with the “80/20 Company” Exclusion
Many multinational groups find that foreign-source dividends and other income earned by domestic affiliates are fully or partially subject to state income taxation, even where the federal system provides an exemption. This state-level “leakage” can be material – particularly in high-tax jurisdictions – and is often overlooked because the income appears sheltered at the federal level. For groups with predominantly foreign operations, a starting structure or a restructuring that causes one or more domestic affiliates to qualify as an “80/20 company” can substantially reduce or eliminate state taxation on that income.
