In the Fall of 2025, Bitcoin reached an all-time high of over $120,000. Since then, it fell over 40% to under $70,000 in the first quarter of 2026, before slightly recovering, currently resting around $75,000 as of this writing. With the steep drop in the price of Bitcoin and other cryptocurrencies, a common question from taxpayers is whether they can use the current losses to offset their other income. Large investors and professionals such as Grant Cardone and Shehan Chandrasekera (Head of Tax Strategy at Cointracker) have suggested that cryptocurrency can be sold and bought back immediately to claim the tax benefits. As with most things, the answer to this is not as simple as they portray, and many commentators, influencers, and sometimes professionals, miss the intricacies of cryptocurrency taxation.

The 2025 court decision, Kwong v. United States, is quietly gaining traction among tax professionals for exactly these reasons. Its implications could be far-reaching, potentially opening the door to refund claims, penalty abatements, and revived tax deadlines that many assumed were long closed. But there’s a catch: the opportunity to act may be time-sensitive, and the window to preserve claims could begin closing in just a few short weeks. Here’s what the court actually decided and why it matters now.
