📋 A clear, practical guide to understanding the wash sale rule and its application to cryptocurrency in 2025 and 2026—covering current law, proposed legislation, tax-loss harvesting strategies, compliance, and key risks.
The wash sale rule is a tax provision under Internal Revenue Code (IRC) Section 1091 that prevents investors from claiming a tax deduction for a loss on the sale of stock or securities if they acquire substantially identical stock or securities within a 61-day window: 30 days before or 30 days after the sale[reference:0].
When a wash sale occurs, the loss is disallowed for tax purposes. Instead, the disallowed loss is added to the cost basis of the newly acquired securities, effectively deferring the loss rather than eliminating it. This rule is designed to prevent investors from generating artificial tax losses while maintaining essentially the same investment position.
💡 Key Takeaway: The wash sale rule applies to stocks and securities. The critical question for cryptocurrency investors is whether digital assets are classified as securities under the tax code—and that classification is exactly what is being debated and legislated in 2025 and 2026.
The rule applies to both individual investors and traders, and it covers acquisitions through purchases, contracts to purchase, and options. The determination of what constitutes "substantially identical" securities is facts-and-circumstances based, though the IRS has provided some guidance over the years.
As of mid-2026, the wash sale rule does not apply to most cryptocurrencies under current law[reference:1][reference:2]. The IRS classifies cryptocurrencies like Bitcoin and Ethereum as property, not securities[reference:3][reference:4]. Because IRC Section 1091 applies only to "stock or securities," crypto transactions fall outside its scope.
This classification has created a notable tax advantage for crypto investors: you can sell a cryptocurrency at a loss and immediately repurchase the same asset while still claiming the tax deduction[reference:5]. This strategy, known as tax-loss harvesting, is unavailable to stock investors who must wait 30 days to avoid triggering the wash sale rule[reference:6].
⚠️ Important nuance: While most cryptocurrencies are not subject to the wash sale rule, tokenized securities—digital assets that represent traditional securities—may already be subject to the rule[reference:7]. Additionally, spot Bitcoin ETFs are structured as securities and are subject to wash sale rules[reference:8].
It is also worth noting that "wash trading"—the illegal practice of trading with oneself to artificially inflate volume—is a separate concept and is prosecuted by the IRS and other agencies[reference:9]. This article focuses on the tax wash sale rule, not market manipulation.
While the wash sale rule does not currently apply to crypto, there is significant legislative momentum to change that. Several bills introduced in 2025 and 2026 would extend the wash sale rule to digital assets[reference:10].
Introduced in late 2025 by Rep. Max Miller and others, the Digital Asset Protection, Accountability, Regulation, Innovation, Taxation, and Yields (PARITY) Act would extend wash sale rules under IRC § 1091 to digital assets[reference:11][reference:12]. It also includes provisions for stablecoins, mark-to-market elections, and staking rewards[reference:13].
Senator Cynthia Lummis introduced comprehensive digital asset tax legislation in July 2025 that would revise Section 1091 to cover "specified assets"—both securities and digital assets—applying the 30-day wash sale rule to crypto[reference:14][reference:15].
Introduced by Rep. Jodey Arrington in June 2026, this bill would amend IRC Section 1091 to apply wash sale rules to digital assets[reference:16][reference:17]. It is currently in the early stages of the legislative process[reference:18].
The One Big Beautiful Bill Act, signed on July 4, 2025, did not include crypto tax provisions[reference:19]. While some sources initially reported that it extended wash sale rules to crypto[reference:20][reference:21], these provisions were removed before final passage[reference:22].
📌 Status as of July 2026: None of these bills have been enacted into law. The legislative process is ongoing, with the PARITY Act and H.R. 9172 in various stages of committee review[reference:23]. Taxpayers should monitor developments closely, as changes could be enacted with retroactive effect or apply to future tax years.
Tax-loss harvesting is the practice of selling assets at a loss to offset capital gains and reduce your tax liability. In the crypto space, this strategy is currently more powerful than in traditional markets because the wash sale rule does not apply[reference:24].
⚠️ Risk of legislative change: If wash sale legislation is enacted, this strategy may no longer be available. Some proposed bills could apply retroactively to transactions in 2025 or 2026. Investors using this strategy should be aware of the potential for changes[reference:26].
For investors with significant gains, tax-loss harvesting can be a valuable tool. However, it is not without complexity—you must track cost basis across multiple wallets and exchanges, and the IRS has increased enforcement with the new Form 1099-DA reporting requirements starting in 2025[reference:27].
Whether or not the wash sale rule applies, all cryptocurrency transactions must be reported to the IRS. Understanding the reporting requirements is essential for compliance.
Even though the wash sale rule does not currently apply, accurate record-keeping is critical. If legislation passes, you will need historical data to determine whether past transactions were wash sales. Many investors use crypto tax software to automate tracking and reporting.
This table summarizes the key differences between how the wash sale rule applies to cryptocurrencies (currently) versus traditional securities.
| Feature | Cryptocurrency (Current) | Stocks & Securities |
|---|---|---|
| Wash sale rule applies? | No (generally)[reference:32] | Yes[reference:33] |
| 30-day waiting period required? | No | Yes[reference:34] |
| Immediate repurchase allowed? | Yes[reference:35] | No |
| Loss disallowed if repurchased? | No | Yes |
| Basis adjustment required? | No | Yes |
| Reporting form | Form 8949, Schedule D[reference:36] | Form 8949, Schedule D, Form 1099-B |
| Tax-loss harvesting | More flexible[reference:37] | Restricted by 30-day rule |
| Tokenized securities | May be subject to rule[reference:38] | N/A |
Note: This comparison reflects current law as of July 2026. Proposed legislation would make the rules for crypto substantially similar to those for securities.
Situation: An investor purchased 1 Bitcoin for $60,000 in early 2025. By December 2025, Bitcoin has dropped to $40,000, creating a $20,000 unrealized loss.
Strategy under current law:
Outcome: The investor maintains their Bitcoin exposure while realizing a tax benefit that would be unavailable to a stock investor under the wash sale rule[reference:40].

Under current law in 2025, the wash sale rule generally does not apply to most cryptocurrencies. The IRS classifies cryptocurrencies like Bitcoin and Ethereum as property, not securities, and IRC Section 1091 applies only to stocks and securities[reference:49]. However, there is significant legislative activity to change this, and some tokenized securities may already be subject to the rule[reference:50].
As of mid-2026, several bills have been introduced to extend the wash sale rule to digital assets, including the PARITY Act and H.R. 9172[reference:51][reference:52]. However, none have been enacted into law as of July 2026. The rule does not yet apply to crypto, but taxpayers should monitor legislative developments closely as the situation could change.
The wash sale rule (IRC Section 1091) disallows a tax deduction for a loss on the sale of stock or securities if you acquire substantially identical stock or securities within 30 days before or after the sale[reference:53]. The disallowed loss is added to the basis of the new position, deferring the loss rather than eliminating it.
Yes, under current law in 2025, you can sell cryptocurrency at a loss and immediately repurchase the same asset while still claiming the tax deduction[reference:54]. This is because the wash sale rule does not apply to property classified as crypto[reference:55]. This strategy is commonly referred to as tax-loss harvesting.
The PARITY Act is a bipartisan bill introduced in late 2025 that would extend the wash sale rules under IRC Section 1091 to digital assets[reference:56]. If enacted, it would close the "fake-loss loophole" by requiring a 30-day waiting period before repurchasing a digital asset sold at a loss to claim the deduction[reference:57].
H.R. 9172, the "Applying Existing Tax Anti-Abuse Rules to Digital Assets Act," was introduced in June 2026[reference:58]. It would amend IRC Section 1091 to apply wash sale rules to digital assets, closing the loophole that currently allows crypto investors to claim losses while immediately repurchasing the same asset[reference:59].
Maintain detailed records of all your crypto transactions, including dates, amounts, cost basis, and sale proceeds[reference:60]. Use crypto tax software to track your positions. If you use tax-loss harvesting, consider that the rules may change retroactively or prospectively[reference:61]. Consult a tax professional for personalized guidance.
Monitor the IRS website for official guidance, follow updates from the House Ways and Means Committee, and check reputable tax news sources. As of July 2026, the wash sale rule does not apply to crypto, but legislative activity is ongoing and the situation can change rapidly.
