The IRS and Treasury issued Notice 2026-50 on August 14, 2026, giving taxpayers a temporary alternative when the EPA's e-GGRT system is unavailable for substantiating permanent storage under the Section 45Q carbon capture credit. This matters for project developers and investors because reporting delays can stall credit claims and affect project economics. The notice does not change the underlying storage requirements, only the method of proof when the electronic tool is down. Companies should document any period of unavailability and keep records to support alternative submissions. This is a narrow but practical fix for a gap that could otherwise slow down carbon capture projects relying on 45Q incentives.
