The wash sale rule is one of the most discussed topics in crypto tax circles right now — and also one of the most misunderstood. Some people think it already applies to crypto. Others take the current exemption for granted without realizing it could change quickly. Here's where things actually stand.
Current Status (As of 2025)
The IRS wash sale rule (Section 1091) currently does not apply to cryptocurrency. Crypto is not classified as a "security" under that rule. This means you can sell crypto at a loss and immediately repurchase it to capture the tax loss while maintaining your position.
What Is the Wash Sale Rule?
The wash sale rule prevents investors from claiming a tax loss when they sell a security and then buy a "substantially identical" security within 30 days before or after the sale (a 61-day window total).
When triggered, the loss is disallowed — you can't claim it on your taxes. Instead, the disallowed loss gets added to the cost basis of the repurchased security, deferring the loss to a future sale.
This rule was designed to prevent investors from creating "paper losses" while maintaining their investment positions. It applies to stocks, bonds, ETFs, and mutual funds — but Congress specifically excluded commodities and currencies from the original legislation.
Why Crypto Currently Escapes the Rule
Cryptocurrency is treated as property by the IRS, not a security. Since Section 1091 specifically covers securities, crypto falls outside its scope. This creates a significant advantage: you can harvest crypto losses and immediately repurchase without the wash sale disallowance.
In practice, this means a crypto investor can:
- Identify a cryptocurrency that's below their cost basis
- Sell it to realize the loss
- Immediately (same day, even same minute) repurchase the same amount
- Claim the loss on their taxes
- Still maintain their full position going forward
This strategy doesn't work with stocks. If you sell Apple stock at a loss and buy it back within 30 days, the loss is disallowed. With Bitcoin, there's no such restriction today.
Proposed Legislation: The Risk Ahead
Multiple bills have been introduced in Congress that would extend wash sale rules to cryptocurrencies. The most notable was the Lummis-Gillibrand Responsible Financial Innovation Act, which included crypto wash sale provisions.
The Biden administration's budget proposals repeatedly included applying wash sale rules to crypto starting in 2024 and 2025. While none of these proposals have become law as of 2025, the direction of travel is clear.
Legislative Risk Is Real
There have been years of legislative proposals to extend wash sale rules to crypto. If you're planning tax loss harvesting strategies that rely on the current exemption, be aware this could change. Legislation typically applies to the current tax year or future years, not retroactively — but timing can matter.
Tax Loss Harvesting Strategies That Still Work
Same-Day Repurchase (Current Window)
As long as the wash sale rule doesn't apply to crypto, you can sell and immediately repurchase. This is the most powerful form of crypto tax loss harvesting — you capture the loss without any gap in market exposure.
Selling Into a Correlated Asset
Even if wash sale rules eventually extend to crypto, you can still harvest losses by selling Bitcoin and buying Ethereum, or vice versa. These are different assets, so even under stock-like wash sale rules, they wouldn't be "substantially identical."
Year-End Portfolio Review
Systematically review your portfolio in November/December each year. Identify positions with unrealized losses and evaluate whether harvesting makes sense given:
- Your realized gains for the year that need offsetting
- The size of the loss and resulting tax savings
- Transaction costs (gas fees, exchange spreads)
- Whether you want to maintain the position long-term
What the Wash Sale Rule Doesn't Affect Right Now
Even if wash sale rules applied to crypto tomorrow, these strategies would still work:
- Switching between similar but different assets — BTC and ETH aren't "substantially identical"
- Using the loss to offset realized gains — the loss is only disallowed if you repurchase substantially identical
- Waiting 31 days before repurchasing the same asset
- Carry-forward of excess losses — these would not be affected
Should You Rush to Harvest Losses Before Legislation Passes?
Many financial advisors suggest that if you're going to harvest crypto losses, doing so before the wash sale exemption potentially goes away makes sense — assuming you have losses to harvest and the strategy makes financial sense for your situation.
However, don't make poor investment decisions just to capture tax benefits. The tax savings need to be weighed against:
- Transaction costs
- Potential market gains you'd miss during a repurchase gap
- The overall tax efficiency of your portfolio

Conclusion
The wash sale rule currently doesn't apply to crypto, giving tax-savvy investors a meaningful advantage over stock investors. But Congress has had this on the radar for years, and it's a matter of when, not if, this exemption closes.
Use the current window strategically — but don't let tax optimization drive poor investment decisions, and stay alert to legislative changes that could affect your strategy.
