The Kwong v. US Ruling
On November 25, 2025, the U.S. Court of Federal Claims ruled in Kwong v. United States that Internal Revenue Code Section 7508A(d) required mandatory postponement of federal tax deadlines during the COVID-19 national disaster period. The court found the IRS lacked authority to assess failure-to-file penalties, failure-to-pay penalties, and underpayment interest on obligations due between January 20, 2020, and July 10, 2023.
