Ventes de lavage et crypto : Naviguer dans les règles de l'IRS et les stratégies de planification

A wash sale occurs when you sell a security or asset at a loss and buy the same or a 'substantially identical' asset within 30 days before or after the sale. In traditional stocks, the IRS disallows claiming the loss if a wash sale occurs, adding the disallowed amount to your cost basis of the new purchase. In crypto, the IRS hasn't explicitly defined wash sales, but the rules are generally believed to apply similarly. The goal is to prevent taxpayers from claiming losses purely for tax benefits while effectively maintaining their position.

The IRS has not issued specific guidance on wash sales involving cryptocurrencies. They treat crypto as property, similar to stocks and securities. This means, in theory, wash sale rules should apply. However, the IRS has explicitly stated that wash sale rules do not currently apply to cryptocurrencies in the same way as stocks, creating uncertainty. Tax professionals widely agree that, practically, wash sale rules likely do apply, but enforcement and reporting are inconsistent. Until the IRS clarifies, it's safest to assume wash sale rules could affect your crypto trades.

Stablecoins like USDC, USDT, and DAI are often used to 'cycle' funds quickly within short timeframes. For example, you sell Bitcoin at a loss, buy USDC, then buy Bitcoin again within days. Although this might seem harmless, the IRS could view this pattern as a wash sale if it involves 'substantially identical' assets. The challenge is that stablecoins are considered a different asset class, but the intent to maintain the position can trigger the wash sale rules. Frequent cycling with stablecoins increases the risk of disallowed losses and complicates your tax reporting.

Example 1: - January 1: You buy 1 BTC at $20,000. - January 20: You sell 1 BTC at $19,000, realizing a $1,000 loss. - January 25: You buy 1 BTC again at $19,500. In this case, if wash sale rules apply, your $1,000 loss is disallowed. Instead, it gets added to your new basis of $19,500, making your new cost basis $20,500. Example 2: - You sell 10 ETH at a loss. - You immediately buy USDC (a stablecoin). - A week later, you buy ETH again at a lower price. If the IRS considers ETH and USDC as 'substantially identical' or if cycling was meant to avoid taxes, the loss on ETH sale could be disallowed. The key factor is the timing and intent behind these trades.

The IRS has not issued clear rules on crypto wash sales. Their 2022 guidance clarified wash sale rules for stocks but did not extend this to crypto. The crypto community is divided: some argue wash sale rules don't apply yet, while others treat crypto as securities, applying the same rules. Enforcement is inconsistent, and reporting is up to individual taxpayers and their accountants. This ambiguity makes planning difficult but underscores the importance of careful record-keeping.
