Do wash sale rules apply to cryptocurrency trading?

Crypto’s appeal is no secret: high volatility, big upside, and a growing place in modern portfolios. But while the market moves fast, the tax code hasn’t kept pace. That disconnect has created room for savvy investors to capitalize, especially when it comes to capital losses.

At the center of the conversation are crypto wash sale rules – or, more accurately, the lack of them.

In this guide, we’ll explain how the wash sale rule works and why it hasn’t been extended to crypto assets. We’ll also explore how it relates to tax loss harvesting rules and what it means for investors looking to offset gains and reduce their tax bills before the loophole closes.

What are wash sale rules?

Wash sale rules, outlined in Section 1091 of the Internal Revenue Code, apply when you sell stocks or securities at a loss and then repurchase the same, or substantially identical, stocks or securities within 30 days before or after the sale. If that happens, the loss is disallowed, and you can’t claim it on your tax return. Instead, the loss is added to the cost basis of the new purchase, deferring the tax benefit until a future sale.

These rules exist to prevent investors from claiming capital losses on sales that don’t reflect a meaningful change in ownership. In short, if you haven’t actually exited the position, you don't get to use the loss to reduce your capital gains taxes.

Do wash sale rules apply to crypto?

This is one of the few areas where current tax law works in favor of crypto investors. Under existing U.S. tax rules, the wash sale rule does not apply to cryptocurrencies.

That’s because the IRS currently classifies digital assets like Bitcoin (BTC) and Ethereum (ETH) as property, not securities. And since the wash sale rule applies only to “stocks or securities,” crypto transactions fall outside its scope. As a result, the wash rule in crypto is essentially nonexistent – for now.

That creates planning opportunities when it comes to tax loss harvesting. Under current U.S. tax rules, if you sell a crypto asset at a loss, the loss is generally recognized for tax purposes even if you repurchase the same asset within the wash sale window.

For example, if your Bitcoin position is down near the end of the year, you could sell it to realize a capital loss and then repurchase Bitcoin shortly thereafter to maintain your market exposure. Under current tax rules, the loss from the sale is still deductible on your tax return.

However, the absence of wash sale rules does not mean that all transactions are risk-free from a tax perspective. General anti-abuse principles, including the substance-over-form doctrine, give the IRS authority to challenge transactions that lack economic substance or are undertaken solely for tax avoidance purposes. As with any tax strategy, transactions should reflect a bona fide change in economic position.

Policymakers have periodically discussed extending wash sale rules to digital assets, but no such legislation has been enacted to date. Any future changes would require action by Congress and could affect how crypto investors approach tax loss harvesting strategies.

What’s tax loss harvesting?

Tax loss harvesting is a tax planning strategy that involves selling assets that have declined in value in order to realize capital losses. Those losses can be used to offset capital gains, and if losses exceed gains, up to $3,000 per year can be applied against ordinary income, with any remaining losses carried forward.

In the context of digital assets, tax loss harvesting can offer additional flexibility under current U.S. tax rules. Because cryptocurrencies are not subject to wash sale rules, investors may be able to recognize a loss and subsequently reestablish a position in the same asset without disallowing the loss, provided the transaction reflects a bona fide disposition.

For example, suppose you purchased ETH at $4,000 and its value later declined to $2,000. If you also realized $3,000 of taxable gains elsewhere, you could sell the ETH to recognize a $2,000 capital loss and use that loss to offset a portion of your gains. Depending on market conditions and investment objectives, you may then choose to reestablish exposure to ETH to maintain your desired portfolio allocation.

In traditional securities markets, wash sale rules generally require investors to wait 30 days before repurchasing the same or substantially identical asset in order to preserve a realized loss. Because those rules do not currently apply to cryptocurrencies, investors are not subject to the same mandatory waiting period, though broader tax and investment considerations still apply.

What are the pros and cons of crypto tax loss harvesting?

Crypto tax loss harvesting can be a smart way to reduce your tax bill—especially in volatile markets. But like any strategy, it comes with trade-offs. Here's an overview of the key benefits and potential risks to keep in mind:

Benefits

• Tax efficiency: Realizing losses to offset capital gains can meaningfully reduce your year-end tax burden, freeing up cash for reinvestment or other planning needs.
• Uninterrupted market exposure: In contrast to traditional markets, crypto investors are not subject to a mandatory 30-day waiting period under current wash sale rules, which can provide greater flexibility in managing portfolio exposure during volatile market conditions.
• Opportunistic in volatile markets: Frequent price fluctuations create more opportunities to realize short-term losses without abandoning long-term conviction.
• Offsetting ordinary income: If losses exceed gains, investors can apply up to $3,000 per year against ordinary income and carry forward any excess indefinitely.

Limitations

• Policy risk: Lawmakers have proposed applying wash sale rules to digital assets. If enacted, such changes could limit the availability of certain tax loss harvesting strategies going forward.
• Cost drag: Frequent trading may rack up network fees, spreads, or slippage, particularly for tokens on less liquid exchanges.
• Execution risk: Market prices can move unexpectedly between transactions, potentially resulting in higher reentry costs or changes in portfolio exposure.
• Recordkeeping burden: Active tax loss harvesting demands detailed tracking of dates, cost basis, and transactions, often requiring specialized tax software or professional help.
• Distraction from strategy: Over-optimizing for taxes can lead to poor trading decisions, short-term thinking, or missed long-term gains.
