July 10, 2026 – A Critical Date to Claim Tax Refunds of Interest and Penalties
The Kwong decision may have provided taxpayers with an opportunity to claim tax refunds of interest and penalties. Meanwhile, the government has recently filed an appeal of the Kwong decision. Because of the government’s appeal, it cannot be stated that the Kwong decision is settled law. This uncertainty creates a problem for taxpayers considering filing a claim for tax refund of interest and penalties under the Kwong decision. Internal Revenue Code Section 6511(a) is considered the general statutory authority to determine the deadline to file an administrative claim for refund of taxes, interest, and penalties.
