The wash sale rule is a well-known tax provision that prevents investors from claiming a loss on securities if they repurchase substantially identical securities within 30 days. But does it apply to cryptocurrency? The short answer is no — at least for now. However, the landscape is evolving. This guide explains the current rules, legislative proposals, and practical strategies for crypto investors in 2026.
The wash sale rule is a U.S. tax provision codified in Internal Revenue Code (IRC) Section 1091. It disallows the deduction of a loss on the sale or disposition of securities if the taxpayer repurchases substantially identical securities within a window of 30 days before or 30 days after the sale.
In simpler terms: if you sell a stock at a loss and then buy it back (or buy a substantially identical security) within 30 days, you cannot claim that loss on your tax return. Instead, the disallowed loss is added to the cost basis of the repurchased securities, which reduces your future gain (or increases your future loss) when you eventually sell.
The rule was designed to prevent investors from creating artificial tax losses — a practice known as tax-loss harvesting — while maintaining essentially the same investment position. Without the wash sale rule, an investor could sell a losing position, claim the loss to reduce taxable income, and immediately repurchase the same position, effectively having their cake and eating it too.
The straightforward answer is no — the wash sale rule does not apply to cryptocurrency under current IRS guidance. However, this is a nuanced area with several important caveats.
The wash sale rule applies specifically to securities as defined under IRC Section 1091. The IRS has consistently treated cryptocurrency as property for federal tax purposes, not as a security. This classification has been reaffirmed in multiple IRS notices and guidance documents, including IRS Notice 2014-21.
This is where it gets more complex. While direct cryptocurrency holdings are not subject to the wash sale rule, certain crypto-related securities may be.
If you sell shares of a Bitcoin ETF at a loss and repurchase substantially identical shares within 30 days, the wash sale rule applies.
The IRS has issued several pieces of guidance that clarify the tax treatment of cryptocurrency, though none directly address the wash sale rule (because it doesn't apply).
This is the foundational IRS guidance on cryptocurrency. It established that:
This ruling addressed the tax treatment of hard forks and airdrops:
The IRS is developing a new form, Form 1099-DA (Digital Asset Proceeds), which will be used by brokers to report crypto transactions. This form is part of the IRS's broader effort to increase compliance in the crypto space.
Since cryptocurrency is property and not a security, the wash sale rule does not apply. This means you can sell crypto at a loss and immediately repurchase it (or repurchase within 30 days) and still claim the loss on your tax return. However, the IRS has been clear that tax-loss harvesting with crypto is subject to the economic substance doctrine — the transaction must have a real economic purpose beyond tax avoidance.
The current exclusion of cryptocurrency from the wash sale rule has been identified as a potential tax loophole. Several legislative proposals have been introduced to close this gap.
Introduced in 2024, this bill would extend the wash sale rule to digital assets. Under the proposal, the wash sale rule would apply to any "digital asset" as defined in the bill. The effective date would be retroactive to December 31, 2023, or the date of enactment.
The original Build Back Better Act included provisions that would have extended the wash sale rule to commodities and digital assets. While the BBBA ultimately passed in a modified form (the Inflation Reduction Act), the wash sale provisions were not included in the final version.
Several recent budget proposals from the Biden administration have included provisions to close the crypto wash sale loophole. These proposals have not been enacted but signal a growing legislative interest.
Even though the wash sale rule doesn't apply to crypto, there are several crypto-specific tax considerations to be aware of.
When a hard fork creates new tokens, or when you receive an airdrop, the fair market value of the new tokens is taxable as ordinary income at the time of receipt. This increases your cost basis in the new tokens. If you later sell the tokens, you'll have a capital gain or loss based on the difference between the FMV at receipt and the sale price.
Staking rewards are generally treated as income at the time they are received. The FMV of the staking rewards is included in your gross income. This increases your basis in the tokens, which will affect future capital gains calculations.
Wrapping tokens (e.g., converting ETH to wETH) or using cross-chain bridges may trigger a taxable event. The IRS has not provided specific guidance, but the general principle is that any disposition of property triggers a taxable event.
Non-fungible tokens (NFTs) are treated as property, and the wash sale rule does not apply. However, if an NFT is considered a collectible, it may be subject to a higher capital gains tax rate (up to 28%).
Decentralized finance (DeFi) transactions, such as lending, borrowing, and liquidity provision, can create complex tax situations. Some DeFi transactions may be taxable events, even if you don't realize a gain or loss in the traditional sense.
Given that the wash sale rule does not apply to crypto, investors have more flexibility in tax-loss harvesting. Here are some practical strategies.
Since there is no 30-day restriction, you can sell crypto at a loss and repurchase it immediately (or even on the same day) and still claim the loss on your tax return. This allows you to realize losses to offset gains while maintaining your market position.
Even if the wash sale rule applied to crypto, you could avoid it by trading for a substantially different asset. For example, if you want to maintain exposure to the broader crypto market, you could sell BTC and buy ETH or an index fund. This is not a wash sale because the assets are not substantially identical.
December is a common time for tax-loss harvesting. With crypto, you don't need to worry about the 30-day window, so you can harvest losses right up to the end of the year and repurchase immediately.
The table below compares how the wash sale rule applies (or doesn't apply) to different asset types.
| Asset Type | Wash Sale Rule Applies? | Reason | 30-Day Restriction |
|---|---|---|---|
| Stocks & Bonds | ✅ Yes | Securities under IRC 1091 | Yes |
| ETFs & Mutual Funds | ✅ Yes | Securities under IRC 1091 | Yes |
| Bitcoin ETFs (Futures-based) | ✅ Yes | Securities | Yes |
| Cryptocurrency (Direct) | ❌ No | Property, not a security | No |
| Commodities (Physical) | ❌ No | Property, not securities | No |
| Futures Contracts | ❌ No | Covered under mark-to-market rules | No |
| Crypto-Related Stocks (e.g., COIN) | ✅ Yes | Securities | Yes |
| NFTs | ❌ No | Property (collectibles) | No |
Use this checklist to stay organized and compliant when managing your crypto taxes.
Scenario: Alex is a U.S. taxpayer who holds 2 BTC purchased at different times. He also has realized capital gains from stocks during the year. He wants to offset some of these gains with crypto losses.
Step 1: Alex purchases 0.5 BTC in January 2025 at $45,000 per BTC.
Step 2: He purchases 1.5 BTC in June 2025 at $50,000 per BTC.
Step 3: By December 2025, BTC has dropped to $42,000. Alex sells 1 BTC, realizing a loss of $8,000 (based on his ACB of $50,000 for that lot).
Step 4: The next day, Alex buys 1 BTC back at $42,000.
Tax Outcome: Because the wash sale rule does not apply to cryptocurrency, Alex can claim the $8,000 capital loss on his 2025 tax return — even though he repurchased BTC the next day. He offsets this loss against his capital gains from stocks, reducing his tax liability.
Result: Alex successfully harvested a tax loss while maintaining his BTC exposure. He must keep records of both transactions for his tax filing.

As of 2026, the wash sale rule does not apply to cryptocurrency under current IRS guidance. The IRS treats cryptocurrency as property, not as a security, and the wash sale rule specifically applies to securities. However, legislative proposals have been introduced that would extend the wash sale rule to digital assets.
The wash sale rule is a U.S. tax provision that disallows the deduction of a loss on the sale of securities if you repurchase substantially identical securities within 30 days before or after the sale. The disallowed loss is added to the cost basis of the repurchased securities.
The wash sale rule (IRC Section 1091) applies only to stocks, bonds, and other securities. The IRS treats cryptocurrency as property for tax purposes, not as a security. Therefore, the wash sale rule does not currently apply to crypto transactions.
Yes. There have been legislative proposals to extend the wash sale rule to digital assets, including the Crypto-Asset Wash Sale Act and provisions in the Build Back Better Act. These proposals would treat crypto like securities for wash sale purposes. As of 2026, these proposals have not been enacted, but the landscape could change.
Currently, yes. Because the wash sale rule does not apply to crypto, you can sell crypto at a loss and repurchase it immediately (or within 30 days) and still claim the loss on your tax return. However, you must be mindful of the 'substantially identical' concept and the risk of future legislative changes.
While the wash sale rule doesn't currently apply to crypto, the concept of 'substantially identical' is still relevant if the rule is extended. It generally refers to assets that are nearly identical in nature, such as different tickers of the same ETF or, for crypto, potentially different versions of the same token (e.g., BTC vs. wBTC). The IRS has not provided clear guidance on what constitutes substantially identical for crypto.
There is no need to avoid tax loss harvesting with crypto under current law, as the wash sale rule does not apply. However, you should stay informed about legislative developments. If a new law is passed, it could apply to transactions on or after the effective date. Consult a tax professional for guidance specific to your situation.
You report crypto gains and losses on Form 8949 (Sales and Other Dispositions of Capital Assets) and Schedule D (Capital Gains and Losses) of your federal tax return. You'll need to track your cost basis, sale proceeds, and holding period for each transaction. Crypto tax software can help automate this process.
