Crypto and the Wash Sale Rule
The wash sale rule is one of the most discussed tax topics in crypto because cryptocurrency is currently exempt from it. This creates a significant tax planning advantage that stock investors do not have. Understanding the current rules and proposed changes helps you make the most of this opportunity while it lasts.

What Is the Wash Sale Rule?
The wash sale rule (IRC Section 1091) prevents investors from claiming a tax loss on an asset if they purchase a substantially identical asset within 30 days before or after the sale. The rule exists to prevent investors from selling at a loss purely for tax benefits while maintaining their economic position.
For stocks, if you sell shares at a $5,000 loss and buy the same stock back within 30 days, the $5,000 loss is disallowed. Instead, the loss is added to the cost basis of the repurchased shares, deferring the benefit until you eventually sell without triggering another wash sale. This effectively prevents the immediate tax benefit of the loss.
Crypto's Current Exemption
The wash sale rule applies to "stock or securities." The IRS classifies cryptocurrency as property, not as stock or securities. Therefore, under current law, the wash sale rule does not apply to crypto transactions. You can sell Bitcoin at a loss and immediately buy it back, claiming the full tax loss without any disallowance.
This is a major advantage over stock investors. A crypto investor can sell during a market dip, realize the loss for tax purposes, immediately repurchase the same token, and continue holding their position. The only cost is transaction fees. Stock investors must wait 31 days or buy a different (not substantially identical) investment.
Proposed Legislation
Multiple legislative proposals have included provisions to extend the wash sale rule to digital assets. The Build Back Better Act, the Inflation Reduction Act negotiations, and various standalone bills have addressed this. While none have been enacted as of this writing, the direction of legislation strongly suggests crypto will eventually be subject to wash sale rules.
When enacted, the crypto wash sale rule would likely mirror the stock version: if you sell crypto at a loss and repurchase the same or substantially identical crypto within 30 days, the loss would be disallowed. The definition of "substantially identical" for crypto could be complex, particularly for wrapped tokens, staking derivatives, and tokens with similar functions.
Using the Current Exemption
While crypto remains exempt from the wash sale rule, take advantage through aggressive tax-loss harvesting. Whenever a crypto position is below your cost basis, consider selling and immediately repurchasing to realize the loss. This is especially valuable during market corrections when many positions may be underwater.
Automate this process using crypto tax software that identifies harvesting opportunities. Some investors implement a systematic approach, harvesting losses whenever a position drops by more than a set percentage (like 10%). The key benefit is reducing your current tax bill while maintaining the exact same portfolio composition, with no 30-day gap in exposure.
Planning for Potential Changes
Plan proactively for the likely extension of wash sale rules to crypto. Harvest available losses now while the exemption exists. If wash sale rules are enacted, you will still be able to tax-loss harvest, but you will need to wait 31 days before repurchasing or buy a different asset during the waiting period.
Familiarize yourself with strategies stock investors use to work around wash sale rules, such as buying a correlated but not substantially identical asset. For example, selling ETH at a loss and buying SOL to maintain smart contract platform exposure (though the definition of substantially identical for crypto is unclear). Stay informed on legislative developments so you can adjust your strategy promptly.
Frequently Asked Questions
Does the wash sale rule apply to crypto?
Currently, no. The IRS wash sale rule (Section 1091) applies to stocks and securities. Since the IRS classifies crypto as property (not a security), the wash sale rule does not apply. You can sell crypto at a loss and immediately repurchase it, claiming the tax loss. However, proposed legislation may change this.
What is the 30-day wash sale window?
For stocks, the wash sale rule disallows a loss deduction if you purchase a substantially identical security within 30 days before or after the sale at a loss (creating a 61-day window). The disallowed loss is added to the cost basis of the replacement security. This rule currently does not apply to crypto.
When might the wash sale rule apply to crypto?
The Build Back Better Act and other proposed legislation have included provisions to extend the wash sale rule to digital assets. While no law has been enacted yet, it is widely expected that crypto will eventually be subject to wash sale rules. Monitor legislative developments and plan accordingly.
