Do Wash Sale Rules Apply to Crypto in 2025
The short answer is no. Wash sale rules under Section 1091 of the Internal Revenue Code apply to securities. The IRS currently classifies cryptocurrency as property, not securities. So the rule technically does not apply to crypto trades.
But that straightforward answer hides real complexity. It also hides risk.
What the wash sale rule actually does
Section 1091 disallows a loss deduction when you sell or trade a security at a loss and buy a "substantially identical" security within 30 days before or after the sale. The rule is designed to stop investors from harvesting tax losses while keeping their economic position intact.
Crypto is not a security under this code section. Therefore the rule does not apply. You can sell Bitcoin at a loss, buy it back the same day, and claim the loss on your taxes.
Many traders do exactly that. It is a common tax-loss harvesting strategy in crypto.
Why that answer may not last
Legislative proposals have repeatedly sought to close this gap. In 2021, the infrastructure bill contained language that did not ultimately extend wash sale rules to crypto. But similar provisions have appeared in subsequent legislative sessions. The Taxpayer Certainty and Disaster Tax Relief Act of 2020 included a provision that would have applied wash sale rules to digital assets. It did not pass.
The pattern is clear. Policymakers know the gap exists. They have tried to close it. They will likely try again.
No one can predict whether or when such a law would pass. But anyone relying on wash sale treatment for crypto losses should understand that the ground can shift.
The IRS has other tools
Even without Section 1091, aggressive loss harvesting can attract attention. The IRS can challenge transactions under the economic substance doctrine. If a sale has no real economic effect other than tax avoidance, the loss may be disallowed.
Close-in-time round trips - buy, sell, buy back within hours - are the most vulnerable. A pattern of such trades may look like something other than genuine market activity.
The IRS also has the authority to recharacterize transactions under step-transaction and substance-over-form doctrines. These are broad, flexible tools. They do not require a specific statute like Section 1091.
Tax software gets this wrong
Some crypto tax software platforms automatically flag crypto wash sales. This is incorrect under current law. The flags appear because the software applies securities rules to property transactions by default.
If you use tax software and see a wash sale warning on a crypto trade, check the settings. Many platforms have a toggle for "apply wash sale rules to crypto." The default is often on. Turn it off unless you disagree with the current legal interpretation.
This is not a small detail. Incorrect wash sale flags can lead to unnecessary tax liability. They can also trigger IRS notices if the flagged amounts are large.
What this means for your trades
The current rules are favorable to crypto traders. You can harvest losses more aggressively than you could with stocks or ETFs. But favorable rules are not permanent rules.
Consider documenting your trading rationale. If you sell a crypto asset and buy it back quickly, note the reason - a market signal, a change in fundamentals, a risk management decision. Good records protect you if the IRS later questions the transaction.
Also consider the timing of any legislative change. If a wash sale rule for crypto were enacted, it would likely apply to trades after the effective date. Losses harvested before that date would probably be unaffected. But again - no one knows the timing.
Bottom Line
As of 2025, wash sale rules do not apply to cryptocurrency. You can sell at a loss and rebuy immediately. The IRS has classified crypto as property, not securities, and Section 1091 is silent on property.
But the legislative pressure is real. And the IRS has other doctrines it can use if it sees abuse.
Tax software is often wrong about this. Double-check your settings.
The current answer is no. The future answer may be different.
