Relief from underpayment interest, failure-to-file penalties, and failure-to-pay penalties—as well as relief from IRS filing deadlines that arose during the COVID-19 pandemic—may be possible under two recent federal cases from the US Tax Court and the US Court of Federal Claims. Specifically, the recent Kwong decision indicates that the period of the COVID-19 federally declared disaster extended from January 20, 2020 to July 10, 2023. Filing deadlines that would have normally occurred and interest and penalties that would have normally accrued during this period may have been suspended under the reasoning articulated in Kwong. Taxpayer deadlines for seeking relief are fast approaching, and the time to review pandemic-era tax filings and tax accounts is now.
