Crypto Wash Sale Rule 2026 – The Opportunity Window for US Investors

The wash sale rule prevents stock investors from claiming losses after quickly rebuying the same asset. Crypto is currently exempt – a valuable tax planning opportunity that may not last.

What Is the Wash Sale Rule?

The IRS wash sale rule (Section 1091) disallows a capital loss deduction if you buy the "substantially identical" security within 30 days before or after the sale at a loss.

Example with stocks: Sell AAPL at a $5,000 loss on Dec 20. Buy AAPL back Dec 30. Loss is disallowed – the $30-day window was triggered.

Crypto Is Currently Exempt

Cryptocurrency is classified as property, not a security. The wash sale rule only applies to securities. Therefore, you can currently:

• Sell Bitcoin at a loss on December 28
• Buy Bitcoin back on December 29
• Still claim the full loss on your taxes

This creates a powerful tax-loss harvesting opportunity unavailable to stock investors.

Tax-Loss Harvesting Strategy for Crypto

1. Identify crypto holdings with unrealized losses late in the year
2. Sell to "realize" the loss before December 31
3. Immediately repurchase the same crypto if you want to maintain exposure
4. The loss offsets capital gains dollar-for-dollar
5. Excess losses up to $3,000 offset ordinary income; remainder carries forward

Real Numbers Example

You have $20,000 in Bitcoin gains and $15,000 in ETH losses (unrealized).

• Sell ETH to realize $15,000 loss
• Immediately rebuy ETH
• Net taxable gain: $20,000 − $15,000 = $5,000 (instead of $20,000)
• Tax saved at 20% long-term rate: $3,000

Pending Legislation: The Risk to Watch

Congress has repeatedly proposed extending the wash sale rule to crypto. The Build Back Better Act (2021) included it. Several 2023-2025 bills also proposed it. As of 2026, it has not passed – but the risk is real.

If/when enacted, there will likely be a transition period. Stay alert to legislative updates.

Canada Has a "Superficial Loss" Rule

For Canadian readers: Canada does have a superficial loss rule that applies to crypto. If you repurchase within 30 days, the loss is denied. This is different from the US – check your local rules.
