What Is All the Hype About Covid-Related Interest? by Robert S. Horwitz

On February 6, 2026, Western Digital Corp. filed a refund suit in the Court of Federal Claims seeking the refund of $20,764,747 of underpayment interest that accrued during the period of the federally declared disaster during Covid-19. Western Digital Corp. v. United States, No. 26-215. Richard Rubin reported on the case on February 16, in an article entitled Tax Deadlines Accidentally Got Turned Off for Three Years. Now What? This led to blogs being posted about how taxpayers should file claims for refund of interest on tax that accrued during the Covid pandemic. So, what is all the fuss about?
