The suit is about disaster relief provisions enacted during the COVID-19 pandemic that suspended certain federal tax deadlines for more than three years — from January 20, 2020, through July 10, 2023.
The ruling affects failure to file, and failure to pay penalties, as well as ES penalties and underpayment interest accrued during that period. The IRS has appealed the decision, so the law is still unsettled. July 10, 2026 is the deadline to file a protective Form 843, to stop the statute of limitations.
I need to figure out how to query the homebase for years 2019 through 2022 to see who may have a claim.
