Tax-loss harvesting is a popular strategy among crypto traders. However, the question of whether the wash sale rule applies to cryptocurrency remains a moving target. This guide explains the current status for 2025 and 2026, examines pending legislation, and outlines the risks you need to know.

The wash sale rule (IRC Section 1091) is a U.S. tax regulation designed to prevent investors from claiming an artificial tax loss. It applies when you sell a security at a loss and then purchase a "substantially identical" security within 30 days before or after the sale date.
If a wash sale occurs, the loss is disallowed for tax purposes. Instead, the disallowed loss is added to the cost basis of the new position, which can reduce future taxable gains. This rule is primarily aimed at stocks, bonds, and other securities.
The rule prevents taxpayers from manipulating their tax liability by selling losing assets to realize a loss, only to immediately repurchase the same asset to maintain their market position. It forces taxpayers to have a genuine change in economic exposure to claim a loss.
As of mid-2026, the federal wash sale rule does NOT apply to cryptocurrency. This is because the Internal Revenue Service (IRS) classifies virtual currency as property (under IRS Notice 2014-21), not as a security. The statutory language of Section 1091 specifically refers to "stocks and securities," which excludes property.
The IRS explicitly stated in Notice 2014-21 that virtual currency is treated as property for federal tax purposes. Therefore, the wash sale provisions, which are strictly limited to securities, do not apply to cryptocurrency trades. This remains the official guidance for the 2025 and 2026 tax years unless new legislation is passed.
Most U.S. states conform to federal tax rules, meaning they also do not apply wash sale rules to crypto. However, states like California and New York sometimes have specific conformity statutes that could differ. Always verify your state's current tax guidelines.
While the current rules are favorable for tax-loss harvesting, this landscape is not permanent. Several legislative proposals have been introduced in recent sessions of Congress aimed at closing this loophole.
Bills such as the "Wash Sale Loss Act of 202X" and proposals embedded in larger budget reconciliation packages have sought to extend the wash sale rule to cover digital assets. The rationale is to prevent taxpayers from using crypto to generate artificial losses while maintaining their economic position.
Tax laws change. To verify the current status, regularly check the official IRS website for updates, review the Congress.gov database for pending bills, and consult with a qualified tax professional who specializes in digital assets.
Even if the wash sale rule were extended to crypto, the definition of "substantially identical" would create massive complexity. In the stock market, it's relatively clear (e.g., IBM common stock vs. IBM common stock). With crypto, the lines are blurred.
Given this ambiguity, aggressive tax positions carry significant risk of being challenged by the IRS under the economic substance doctrine or the step transaction doctrine, regardless of the letter of the law.
The table below contrasts the tax treatment of a loss transaction under current crypto rules (property) versus a hypothetical future where the wash sale rule applies (securities).
| Action | Current Crypto Rules (Property) | If Wash Sale Applied (Securities) | Tax Outcome Difference |
|---|---|---|---|
| Sell 1 BTC at a loss | Loss of $5,000 realized | Loss of $5,000 realized | Same initially |
| Buy back 1 BTC within 24 hours | ✅ Loss remains claimable | ❌ Loss is disallowed (wash sale) | Taxable income is $5,000 higher under wash |
| Cost basis adjustment | New basis = purchase price | New basis = purchase price + disallowed loss ($5,000) | Basis is higher under wash (reduces future gain) |
| Net effect on current year taxes | Lower tax bill by $1,100 (at 22%) | No immediate tax benefit | Significant timing difference |
Assumes a 22% marginal tax rate. The current classification as property allows immediate loss recognition, which is a primary reason legislators are seeking to close this gap.
If you are planning to harvest crypto losses in 2025 or 2026, consider these best practices to manage risk and maintain compliance.
Alex is a UK-based trader (but this scenario illustrates US tax principles relevant to the article). Alex holds 5 ETH purchased for $15,000. In June 2026, ETH drops to $12,000, resulting in a $3,000 paper loss. Alex wants to claim this loss to offset capital gains from a previous trade.
Option 1 (Current Rule): Alex sells the 5 ETH at $12,000 and immediately buys them back. Under the current property classification, Alex can claim the $3,000 loss, reducing his tax liability.
Option 2 (Prudent approach): Alex sells the 5 ETH and waits 31 days before repurchasing. If the price stays the same or drops further, he still captures the loss. If the price rises, he may miss out, but he avoids any potential challenge from the IRS regarding the "economic substance" of the transaction.
Option 3 (Alternative asset): Alex sells ETH and buys 1 SOL (or another large-cap crypto) to maintain market exposure. If SOL moves similarly to ETH, his portfolio remains aligned while he captures the ETH loss.
Outcome: Option 1 offers the immediate tax benefit but carries the highest risk if legislation changes retroactively. Options 2 and 3 are safer, albeit with trade-offs in market timing and asset selection.
Many traders treat the current exemption as permanent. This is dangerous. Pending legislation could pass with retroactive or forward-looking effects.
Even without wash sales, you need to track every trade. Failing to do so leads to incorrect tax filings and potential penalties.
Even if the technical wash sale rule doesn't apply, the IRS can still disallow losses if the transaction lacks a genuine profit motive. Selling and buying back seconds later could be challenged.
While the federal rule doesn't apply, some states have their own rules. Traders in California or New York should check local guidance.
Aggressively swapping between highly correlated assets (like BTC and wBTC) could be viewed as a wash if the IRS ever clarifies the definition.
Crypto taxes are complex. Relying on generic online advice without consulting a tax professional is a common and costly mistake.
Misinterpreting wash sale rules can lead to severe financial penalties. While the rule does not currently apply to crypto, relying on this exemption is not without risk.

Direct answers to the most common questions about crypto and the wash sale rule.
As of mid-2026, the federal wash sale rule (IRC Section 1091) does NOT apply to cryptocurrency because the IRS classifies crypto as property rather than a security. However, pending legislation could change this.
The wash sale rule specifically applies to 'stocks and securities.' Under IRS Notice 2014-21, virtual currency is treated as property, so the statutory definition does not include it.
Yes, several proposals have been introduced to extend the rule to digital assets. As of 2026, none have been enacted, but they remain under consideration in Congress.
The IRS has not provided clear guidance. It likely applies to identical tokens (e.g., BTC to BTC). It is unclear if it applies to different tickers (like BTC vs. wBTC) or different assets (like ETH vs. SOL).
Under current federal rules, yes. However, the IRS could challenge this under the economic substance doctrine. If new legislation is passed retroactively, you could face penalties.
Most states conform to federal rules, meaning they do not apply wash sales to crypto. However, some states may have their own conformity rules. Always check your state's specific tax guidelines.
The safest method is to wait at least 31 days before repurchasing the same asset, or to invest the proceeds into a different, non-substantially-identical asset to maintain market exposure.
If the IRS disallows a claimed loss, you will owe back taxes plus interest. Accuracy-related penalties of 20% to 40% of the underpayment may apply in cases of negligence or substantial understatement.
