The IRS wash sale rule—a cornerstone of tax-loss harvesting for securities—does not currently apply to cryptocurrency. This guide explains why, what it means for your taxes, and how proposed legislative changes could reshape the landscape for digital asset investors.
The wash sale rule, codified in Internal Revenue Code (IRC) Section 1091, is designed to prevent taxpayers from claiming artificial tax losses on transactions that lack genuine economic substance[reference:0].
A wash sale occurs when you sell or dispose of stock or securities at a loss and, within 30 days before or after the sale, you acquire substantially identical stock or securities[reference:1]. The 61-day window (30 days before, the day of, and 30 days after) is the period the IRS scrutinizes[reference:2].
If a wash sale is triggered, you cannot claim the loss on your current-year tax return[reference:3]. Instead, the disallowed loss is added to the cost basis of the replacement securities, deferring the loss until you eventually sell those securities in a non-wash-sale transaction[reference:4].
The rule applies to stocks, bonds, mutual funds, ETFs, options, and futures[reference:5]. It does not apply to cryptocurrency—at least not yet[reference:6].
The critical distinction lies in how the IRS classifies cryptocurrency. Under Notice 2014-21, the IRS treats virtual currency as property for federal tax purposes[reference:7][reference:8]. General tax principles that apply to property transactions apply to cryptocurrency transactions[reference:9].
IRC Section 1091 specifically refers to "stock or securities"[reference:10]. Because cryptocurrency is classified as property—not a security—the wash sale rule does not apply[reference:11]. This classification has been reaffirmed consistently by the IRS, including in subsequent guidance[reference:12].
There is an important exception. Digital assets that represent tokenized versions of stocks or other securities are subject to the wash sale rules[reference:13]. If a tokenized asset represents an underlying security that would itself be subject to wash sale treatment, the rule applies[reference:14]. However, standard cryptocurrencies like Bitcoin and Ethereum are not securities for this purpose[reference:15].
Even though the wash sale rule does not apply, cryptocurrency transactions are still taxable. Understanding what constitutes a taxable event is essential for compliance.
When you sell crypto for less than your cost basis, you incur a capital loss. Capital losses can offset capital gains, and up to $3,000 of net capital losses can offset ordinary income each year[reference:19]. Unused losses can be carried forward to future years[reference:20].
Because the wash sale rule does not apply, crypto investors can sell a losing position and immediately repurchase it—while still claiming the capital loss[reference:21]. This is a form of tax-loss harvesting that is currently available only to crypto investors[reference:22].
Accurate recordkeeping is the foundation of tax compliance. For cryptocurrency, this means tracking every transaction in a way that supports your tax return.
Cost basis is the amount you paid for the crypto, including commissions and fees. When you sell or trade, your basis determines the gain or loss. The IRS generally allows specific identification (choosing which units you are selling) or first-in, first-out (FIFO) methods. Choose a method and apply it consistently.
Reporting cryptocurrency transactions on your tax return involves several forms and schedules. Here is an overview of the key documents.
Since 2020, the IRS has included a question at the top of Form 1040 asking whether you received, sold, exchanged, or disposed of any virtual currency during the tax year. Answering "yes" does not automatically mean you owe tax—it merely alerts the IRS that you have crypto activity.
You must report each sale or exchange of cryptocurrency on Form 8949[reference:27]. This form captures the date acquired, date sold, proceeds, cost basis, and gain or loss for each transaction. Summaries are then transferred to Schedule D.
Schedule D aggregates your capital gains and losses from all sources, including cryptocurrency. The net capital gain or loss flows to your Form 1040.
The IRS has proposed a new Form 1099-DA for digital asset transactions[reference:28]. While not yet finalized, it would require brokers to report digital asset sales and exchanges. The inclusion of a "wash sale loss disallowed" box on the draft form does not mean crypto is subject to wash sale rules—it is for tokenized securities[reference:29].
The wash sale loophole for cryptocurrency has been the subject of legislative and regulatory proposals for several years. While no changes have been enacted as of 2024, the landscape is shifting.
The President's annual budget proposals, including the "Green Book," have consistently called for extending the wash sale rules to digital assets[reference:30][reference:31]. The 2025 Green Book reproposes this change, with an effective date for taxable years beginning after December 31, 2024[reference:32].
Multiple bills have been introduced to apply wash sale rules to digital assets[reference:33]. The original Build Back Better Act, which became the Inflation Reduction Act, contained such a provision[reference:34]. While it did not survive in the final legislation, it signals ongoing congressional interest.
The Treasury Department has also proposed regulations that would expand the wash sale rules to digital assets[reference:35]. However, as of 2024, no final rule has been issued[reference:36].
The table below contrasts how the wash sale rule applies to traditional securities versus cryptocurrency under current law.
| Feature | Securities (Stocks, Bonds, ETFs) | Cryptocurrency (Bitcoin, Ethereum, etc.) |
|---|---|---|
| IRS Classification | Securities | Property[reference:39] |
| Wash Sale Rule Applies? | Yes (IRC §1091) | No[reference:40] |
| Loss Disallowed on Repurchase Within 30 Days? | Yes[reference:41] | No[reference:42] |
| Tax-Loss Harvesting Strategy | Must wait 31 days to repurchase | Can repurchase immediately[reference:43] |
| Basis Adjustment | Disallowed loss added to basis[reference:44] | No adjustment (loss is allowed) |
| Reporting Form | Form 8949, Schedule D | Form 8949, Schedule D[reference:45] |
| Economic Substance Doctrine | May apply to abusive transactions | May apply to transactions lacking substance[reference:46] |
| Proposed Changes | None | Likely to be extended to crypto in future[reference:47] |
Use this checklist to ensure you are meeting your tax obligations and taking advantage of current rules.
Context: Alex purchased 10 ETH for $3,000 each ($30,000 total) in early 2024. By December, the price has fallen to $2,200 per ETH. Alex wants to claim the $8,000 capital loss ($30,000 - $22,000) to offset gains from other investments.
Step 1: Sell the ETH
Alex sells all 10 ETH on December 20 for $22,000. This realizes a capital loss of $8,000.
Step 2: Consider the Wash Sale Rule
Because cryptocurrency is property—not a security—the wash sale rule does not apply[reference:48]. Alex can repurchase ETH immediately without losing the ability to claim the loss[reference:49].
Step 3: Repurchase (Optional)
Alex decides to repurchase 10 ETH on December 21 at $2,200 per ETH, spending $22,000. The repurchase does not trigger a wash sale.
Step 4: Tax Impact
Alex can claim the $8,000 capital loss on their 2024 tax return. The loss offsets $8,000 of capital gains. If there are no gains, up to $3,000 can offset ordinary income, with the remaining $5,000 carried forward to 2025[reference:50].
Outcome: Alex successfully harvests a tax loss while maintaining their position in ETH. This strategy is available because crypto is exempt from the wash sale rule—but Alex should be aware that the economic substance doctrine could apply if the transaction lacks a genuine purpose[reference:51].
Even with the current exemption, taxpayers make errors. Avoid these common pitfalls.

Before making any tax or investment decisions, you should consult with a qualified tax professional who understands your specific situation. The IRS has not issued definitive guidance on all aspects of cryptocurrency taxation, and interpretations may vary.
Key Risks and Considerations:
Always verify current rules and rates from authoritative sources before acting. This guide is not a substitute for professional advice.
No. Under current law, the wash sale rule (IRC §1091) applies only to "stock or securities." Cryptocurrency is classified as property for tax purposes, so the rule does not apply[reference:57][reference:58].
Yes. Because the wash sale rule does not apply, you can sell crypto at a loss and repurchase it immediately while still claiming the loss on your taxes[reference:59].
The economic substance doctrine allows the IRS to disregard transactions that lack a genuine business purpose other than tax avoidance. While the wash sale rule does not apply, the IRS could still challenge a transaction if it has no economic substance[reference:60].
Yes. The Biden administration's Green Book proposals have repeatedly called for extending the wash sale rules to digital assets[reference:61]. Multiple bills have been introduced in Congress[reference:62]. As of 2024, no changes have been enacted.
You report each sale or exchange on Form 8949 and transfer the totals to Schedule D[reference:63]. You must also answer the digital asset question on Form 1040.
For tax purposes, "securities" include stocks, bonds, and similar instruments. "Property" is a broader category that includes real estate, commodities, and cryptocurrency. The distinction matters because certain rules—like the wash sale rule—apply only to securities[reference:64].
Yes. If a digital asset represents a tokenized version of a stock or other security that would itself be subject to the wash sale rule, then the rule applies[reference:65].
Many tax professionals recommend considering tax-loss harvesting while the wash sale loophole exists[reference:66]. However, this is a personal decision that depends on your specific tax situation. Consult a tax professional before acting.
