Crypto Wash Sales Are Still Legal

Unlike stocks, the IRS wash sale rule (Section 1091) does not apply to cryptocurrency as of 2026. You can sell crypto at a loss and immediately rebuy to harvest the tax loss while maintaining your position. This calculator detects wash sale opportunities in your transactions.

Understanding Crypto Wash Sales

What Is a Wash Sale?

A wash sale occurs when you sell an asset at a loss and repurchase the same or "substantially identical" asset within 30 days. For stocks and securities, IRS Section 1091 disallows the loss deduction.

For cryptocurrency, the wash sale rule does not currently apply. The IRS classifies crypto as property, not a security, so Section 1091 doesn't cover it.

How to Use This Strategy

Identify crypto positions with unrealized losses
Sell the position to realize the loss
Immediately repurchase the same crypto
Deduct the loss on your tax return
Your position size stays the same — only your cost basis resets

⚠️ Congress may close this loophole. Monitor IRS guidance and proposed legislation.
