The wash sale rule is one of the most important—and most misunderstood—tax concepts for cryptocurrency investors. This guide explains whether Section 1091 applies to crypto, how the IRS treats digital assets, what tax-loss harvesting means for your portfolio, and what records you need to keep to stay compliant.
The wash sale rule is codified in Internal Revenue Code Section 1091. It is designed to prevent investors from claiming artificial tax losses by selling a security at a loss and then repurchasing the same or a "substantially identical" security shortly after.[reference:0]
Under the rule, if you sell stock or securities at a loss and acquire substantially identical stock or securities within 30 days before or 30 days after the sale (a 61-day window centered on the sale date), the loss is disallowed for tax purposes.[reference:1][reference:2]
The disallowed loss is not lost forever—it is added to the cost basis of the replacement shares. This means you may recognize the loss later when you eventually sell the replacement shares, but you cannot claim it in the current tax year.[reference:3]
The wash sale rule exists to prevent taxpayers from manufacturing losses for tax purposes without meaningfully changing their economic position.[reference:4] If you sell a position and buy it back immediately, you haven't really exited the investment—so the IRS says you shouldn't get the tax benefit of a loss.
The wash sale rule applies to stocks and securities. The critical question for crypto investors is whether cryptocurrency is classified as a "security" for this purpose—and under current IRS guidance, it is not.
The short answer is: Under current IRS guidance, the wash sale rule does not apply to cryptocurrency.[reference:5][reference:6]
In IRS Notice 2014-21, the IRS established that virtual currency is treated as property for federal tax purposes, not as currency.[reference:7][reference:8] The IRS stated:
"Virtual currency is treated as property and general tax principles applicable to property transactions apply to transactions using virtual currency."[reference:9]
Because Section 1091 applies specifically to "stock or securities," and cryptocurrency is classified as property, the wash sale rule does not currently apply to crypto transactions.[reference:10] This is a critical distinction that shapes the entire tax landscape for digital assets.[reference:11]
Crypto exchange-traded products (ETPs) and ETFs may be treated differently. Because these are securities that trade on traditional exchanges, the wash sale rule may apply to crypto ETPs, even though it does not apply to direct crypto holdings.[reference:12] For tax purposes, you should treat crypto ETFs and ETPs like other securities and consult the wash sale rules accordingly.
Similarly, tokenized securities—digital assets that represent underlying stocks or other securities—may also be subject to wash sale rules.[reference:14]
Direct holdings of Bitcoin, Ethereum, and other cryptocurrencies: No wash sale rule (currently). Crypto ETFs, ETPs, and tokenized securities: Wash sale rule may apply.
Even though the wash sale rule does not apply to crypto, you still have tax obligations. Every time you dispose of cryptocurrency, you trigger a taxable event.[reference:15][reference:16]
Buying crypto with fiat and transferring between your own wallets are not taxable events.[reference:17]
| Transaction Type | Taxable Event? | Treatment |
|---|---|---|
| Sell crypto for USD | Yes | Capital gain or loss |
| Trade crypto for crypto | Yes | Capital gain or loss |
| Pay for goods with crypto | Yes | Capital gain or loss |
| Receive crypto as payment | Yes | Ordinary income (FMV at receipt) |
| Staking/mining rewards | Yes | Ordinary income (FMV at receipt) |
| Buy crypto with USD | No | Track cost basis |
| Transfer between own wallets | No | No tax event |
If you hold crypto for one year or less before selling, gains are taxed at your ordinary income tax rate (short-term). If you hold for more than one year, gains are taxed at the lower long-term capital gains rates (0%, 15%, or 20% depending on income).[reference:18]
Because the wash sale rule does not apply to crypto, investors can engage in a strategy called tax-loss harvesting—selling crypto at a loss to offset capital gains or ordinary income, then immediately repurchasing the same asset to maintain market exposure.[reference:19]
Imagine you bought Bitcoin at $80,000 and it's now trading at $60,000. You can:
The loss can offset capital gains from other investments. If your losses exceed your gains, you can deduct up to $3,000 per year against ordinary income, with any remaining losses carried forward to future years.[reference:20][reference:21]
While tax-loss harvesting is a legitimate strategy, the IRS has general anti-abuse rules, including the substance-over-form doctrine. Transactions that lack economic substance or are undertaken solely for tax avoidance may be challenged.[reference:22] Always ensure your transactions reflect a bona fide change in economic position.
Maria bought 1 BTC for $80,000 in January 2025. By December 2025, the price had dropped to $55,000. She sold her BTC, realizing a $25,000 loss. She then immediately bought 1 BTC back at the same price. On her 2025 tax return, Maria claimed the $25,000 capital loss. She had $10,000 in capital gains from stock sales, which were fully offset. The remaining $15,000 loss reduced her ordinary income by $3,000 (the annual limit), with $12,000 carried forward to 2026. Because the wash sale rule does not apply to crypto, this strategy was fully compliant under current law.
The exemption of cryptocurrency from wash sale rules has been described as a "loophole" by some policymakers, and several legislative proposals have sought to close it.[reference:23][reference:24]
As of the latest information, no final law has been enacted that extends wash sale rules to cryptocurrency.[reference:33] However, the political momentum is clear: bipartisan support exists for closing this tax gap, and changes are likely in the coming years.[reference:34]
Tax laws and regulations change. The information in this guide reflects the current understanding as of the publication date. Always verify the latest IRS guidance and consult a qualified tax professional before making tax decisions. Legislative changes could take effect retroactively or with short notice.
Accurate recordkeeping is the foundation of crypto tax compliance. Without good records, you cannot calculate your gains and losses, and you risk incorrect filings.
Many exchanges and tax software platforms can generate transaction reports. However, you should maintain your own records as a backup, especially if you use multiple wallets or decentralized exchanges (DEXs) that do not issue 1099 forms.
The IRS generally recommends keeping tax records for at least three years from the date you filed your return. However, if you have carryover losses or complex transactions, you may want to keep records for seven years or longer. When in doubt, keep them.
Reporting cryptocurrency transactions to the IRS involves several forms. Here's what you need to know.
You report each taxable crypto disposal on Form 8949.[reference:35][reference:36] This form requires:
For the 2025 tax year, new digital asset boxes (G, H, I, J, K, L) have been added to Form 8949 for crypto transactions, separate from traditional securities boxes.[reference:37]
The totals from Form 8949 flow to Schedule D of Form 1040, where your net capital gain or loss is calculated.[reference:38]
Starting in 2025, custodial brokers (including centralized exchanges like Coinbase and Kraken) must issue Form 1099-DA reporting gross proceeds from digital asset sales.[reference:39][reference:40] You must reconcile your Form 8949 entries with any Form 1099-DA you receive.[reference:41]
Every Form 1040 filer must answer the digital asset question: "At any time during [tax year], did you: (a) receive; or (b) sell, exchange, or otherwise dispose of a digital asset?"[reference:42]
Even if you only made a small crypto transaction, you must check "Yes" on the digital asset question. Answering incorrectly can lead to penalties and increased audit risk.
Even experienced crypto investors make tax mistakes. Here are the most common pitfalls.
