No, the wash sale rule does not apply to cryptocurrency as of September 2026. The rule lives in IRC Section 1091, and it only applies to "stock or securities." The IRS has classified cryptocurrency as property, not a security, since Notice 2014-21, and that classification has held ever since, most recently reaffirmed in Notice 2023-34. In practice, that means you can sell a crypto position at a loss, buy back the exact same coin minutes later, and still claim the full capital loss on your taxes, something you are explicitly barred from doing with a stock or ETF in a taxable account. A bipartisan bill introduced in the House in May 2026 would close this gap, but until something actually passes, the loophole is real, legal, and available to use.
What Is the Wash Sale Rule, and Why Doesn't It Cover Crypto?
The wash sale rule exists to stop investors from claiming a tax loss on paper while keeping their actual market position unchanged. Under Section 1091, if you sell a stock or security at a loss and buy that same security, or one the IRS considers "substantially identical," within 30 days before or after the sale, the loss is disallowed for tax purposes and gets added to the cost basis of the new shares instead. The statute's language is specific: it names "stock or securities." Digital assets were never mentioned in the original 1921 statute, and the IRS's 2014 guidance classifying crypto as property, not a security, put it outside the rule's reach entirely. Whether a particular token also gets treated as a security by the SEC for regulatory purposes is a separate question. For federal income tax purposes, the IRS's property classification is what controls, and it's the reason the wash sale rule simply doesn't apply.
How Does the Crypto Tax-Loss Loophole Actually Work?
The mechanics are almost anticlimactic. You sell a crypto position that's worth less than what you paid for it, which locks in a realized capital loss. You then buy back the same amount of the same coin, at any point afterward, including the same day or the same minute, and the loss still counts in full on your tax return. There's no 30-day waiting period, no "substantially identical asset" test to worry about, and no requirement to sit out of the position at all. You end up holding the same coins you held before, at the same market exposure, with a fresh, lower cost basis and a real capital loss you can use to offset gains elsewhere in your portfolio.
What Does This Actually Save You? A Real Example
Say you sold some appreciated stock this year and are sitting on $12,000 in long-term capital gains, taxed at the 15% long-term rate that applies to most middle- and upper-middle-income filers in 2026. Separately, you're holding a crypto position that's down $9,000 from what you paid, but you still want to hold it long-term and don't want to be out of the market. If this were a losing stock position instead of crypto, using it to offset your $12,000 gain would require staying out of that exact position for 31 days to avoid the wash sale rule, accepting real price risk while you wait. Because it's crypto, none of that applies. You sell, lock in the $9,000 loss, and buy the same coin back immediately. That $9,000 loss offsets $9,000 of your $12,000 gain, leaving only $3,000 exposed to tax. At 15%, that's $1,350 you don't owe this year that you would have owed without harvesting the loss, and you never left your crypto position for a single day.
Is There a Catch? Yes: It's a Deferral, Not a Deletion
Buying the coin back immediately resets your cost basis down to the price you repurchased at. The built-in loss doesn't vanish, it moves forward with you. If that crypto later recovers and you eventually sell it for good, your taxable gain will be larger than it would have been if you'd never harvested the loss at all, because you're now measuring the gain from a lower starting point. This strategy defers tax, and can genuinely be worth doing in a year when you need to offset gains or have room against the $3,000 annual limit on losses deducted against ordinary income, but it is not free money. It's a timing tool, not a way to make a real economic loss disappear.
Is This Loophole Going Away?
Probably, eventually, but it hasn't yet. Representatives Max Miller (R-Ohio) and Steven Horsford (D-Nev.) introduced the Digital Asset PARITY Act in the House in May 2026, and one of its central provisions would rewrite Section 1091 to cover "specified assets," a category built to include digital assets alongside stocks and securities. The draft goes further than the current stock rule in one way: it defines "substantially identical" for crypto based on actual economic exposure, explicitly stating that differences in voting rights, trading venue, or even which blockchain an asset lives on don't matter if the economic bet is the same. As of this writing the bill has not become law. Similar proposals have been floated before, including language in the 2021 Build Back Better Act that passed the House but died in the Senate, so there's real precedent for these efforts stalling. Treat the current loophole as a "use it while it lasts" opportunity, not a permanent feature of the tax code.
What Are the Real Risks of Using This Strategy?
- It could close with no warning. If a bill like the PARITY Act passes, it would likely apply prospectively from its effective date, but relying on a loophole that Congress is actively trying to kill is not a strategy to build permanent plans around.
- It's a deferral, not a discount. Every dollar of loss you harvest lowers your future cost basis by the same amount, so part of the tax bill you avoid today shows up as a larger bill whenever you eventually sell for good.
- Recordkeeping gets messy fast. Repeated harvesting across multiple wallets and exchanges means tracking a growing chain of cost-basis resets. Sloppy records here are a real audit headache, even though the strategy itself is legal.
- Not every "crypto" product plays by these rules. A spot Bitcoin ETF is a security, not property, so it is subject to the ordinary wash sale rule even though it holds Bitcoin. Mixing direct crypto holdings with crypto ETFs means two different rulebooks apply to what can feel like the same position.
- None of this changes what you're actually holding. Crypto isn't FDIC- or SIPC-insured, it remains far more volatile than a diversified stock portfolio, and harvesting a loss doesn't reduce the real risk that the position keeps falling after you rebuy it.
How Does This Compare to Tax-Loss Harvesting With Stocks?
The core idea, realizing a loss to offset a gain, is identical. The difference is entirely about timing risk. Our breakdown of tax-loss harvesting and the wash sale rule covers how, with stocks and ETFs, you either have to sit out of a position for 31 days or swap into something similar-but-different to stay invested while you wait out the rule. With crypto, that trade-off disappears entirely, which is exactly what makes the strategy so widely used right now, and exactly what Congress is trying to take away.
