Does the Wash Sale Rule Apply to Crypto? Not Yet, and the Loophole Has a Countdown.

By Ewan Morkel, EA6 min read

A tech employee sells ether at a $24,000 loss and buys it back before lunch, keeping a deduction a stock investor would lose. Why IRC §1091 doesn't reach crypto in 2026, what a harvest is worth, and the bill drafted to reach back to January 1.

A software engineer bought $60,000 of ether in December 2025 and is staring at $36,000 in July 2026. If that were stock, harvesting the loss would mean a choice: sell and sit out of the position for 30 days, or keep the position and keep the paper loss. So does the wash sale rule apply to crypto the same way? No. It never has, and as of July 2026 it still doesn't. The engineer can sell, deduct the $24,000, and own every coin again before lunch. The rule that stops stock investors from doing exactly this has a boundary written into its first sentence, and crypto sits outside it. For now.

The statute

Why the wash sale rule doesn't apply to crypto.

IRC §1091 disallows a loss when you sell shares of stock or securities and acquire substantially identical stock or securities within 30 days before or after the sale, a 61-day window in total. The disallowed loss isn't destroyed; it's added to the basis of the replacement shares and waits for a clean sale. But the statute's reach is right in the operative words: shares of stock or securities. Notice 2014-21 settled crypto's classification back in 2014: for federal tax purposes, virtual currency is property. Property is not stock or securities, so a coin sold at a loss and repurchased the same afternoon produces a deductible loss that a share of Apple in the identical pattern would not.

This is not a gap Congress hasn't noticed. Wash sale extensions for digital assets have been appearing in draft bills since 2021, and none has been enacted. Until one is, the boundary holds, and selling at a loss to capture the deduction while keeping your position is a legal, reportable transaction. The trade name for it is tax-loss harvesting, and crypto is the only major asset class where you can harvest without giving up the asset for a month.

That month is the whole cost of harvesting stock. A stock investor either sits in cash for 31 days and risks the rebound happening without them, or swaps into a correlated replacement that isn't substantially identical. A crypto holder keeps the exact position. Once recognized, the loss behaves like any capital loss: it offsets capital gains dollar for dollar with no cap, then up to $3,000 of ordinary income per year ($1,500 married filing separately) under §1211(b), and whatever is left carries forward indefinitely under §1212(b).

The math

What a $24,000 harvest is worth in 2026.

Harvesting a $24,000 ether loss without leaving the position, 2026.
Ether bought December 2025
$60,000
Value at sale, July 2026
$36,000
Capital loss recognized
$24,000
Offsets $20,000 short-term gain from an RSU sale (32% bracket)
$6,400 saved
Offsets ordinary income, capped at $3,000 by §1211(b)
$960 saved
Carryforward to 2027 under §1212(b)
$1,000
Federal tax saved on the 2026 return
$7,360
Days out of the ether position
0

Tax year 2026, federal tax only, 32% marginal bracket, all positions held under one year. The rebought ether takes a $36,000 basis and a new holding period, so the $24,000 comes back as gain if the price recovers and you sell.

Be honest about what the $7,360 is. The rebought coins carry a $36,000 basis, so if ether climbs back to $60,000 and you sell, the $24,000 returns as taxable gain. Harvesting is mostly deferral, with two real kickers attached. First, rate arbitrage: the loss offsets short-term gains taxed at 32% now, while the rebought coins, held over a year, recover at a 15% or 20% long-term rate. Second, timing: a tax paid years from now is cheaper than the same tax paid in April, and if the coins are still there at death, the basis step-up makes the deferral permanent.

The catch

A same-second rebuy has a real argument against it.

The IRS has one doctrine that doesn't care what §1091 covers. Under §7701(o), a transaction is respected only if it changes your economic position in a meaningful way apart from taxes and you have a substantial non-tax purpose for it. A sale and repurchase executed seconds apart, at the same price, with software placing both orders, is a hard fact pattern on both prongs: nothing changed but the tax return. The penalty structure is what makes this worth respecting. A loss struck down for lacking economic substance carries a strict liability penalty of 20% of the underpayment under §6662(b)(6), 40% if the transaction wasn't disclosed on the return under §6662(i), and §6664(c)(2) shuts off the reasonable cause defense. There is no version of that exam where your preparer talks the penalty away.

My read: the doctrine was codified with engineered shelters in mind, and the IRS has never publicly applied it to an ordinary crypto harvest, so I think a rebuy after real market exposure is defensible and a same-second rebuy is cheap risk-taking for no extra benefit. Crypto's volatility works in your favor here. Waiting even a few days puts genuine two-way price risk between the sale and the repurchase, which is exactly the economic substance the doctrine asks for. Rotating into a different coin for 31 days is cleaner still, and for most people the harvest is worth doing either way.

The countdown

S. 2207 is drafted to reach back to January 1, 2026.

Senator Lummis introduced S. 2207 on July 3, 2025. Section 4 of the bill writes a wash sale rule for digital assets with the same 61-day window as stock, and its effective date as drafted covers taxable years beginning after December 31, 2025. Read that twice: if the bill passed tomorrow with that date intact, a loss harvested in July 2026 would already be inside the rule. The White House digital assets report of July 30, 2025 recommends the same extension, carving out only payment stablecoins, and the Senate Finance Committee has been working the issue since fall 2025.

As of mid-July 2026, nothing has passed. Retroactive loss disallowance is rare, and effective dates usually slide to the date of enactment during markup, so I'd put the odds of a 2026 harvest being unwound retroactively as low, but the drafted date means the odds are not zero. Harvest knowing that. What I wouldn't bet on is the loophole surviving long term: when a Republican Senate bill and the White House both recommend closing it, the disagreement is about when, not whether.

However you time it, report it. Exchanges began filing Form 1099-DA with the IRS for 2025 transactions, so the government already sees your gross proceeds, and basis reporting starts with assets acquired on or after January 1, 2026. The loss itself goes on Form 8949 and Schedule D from your own lot-level records whether or not a form shows up, and the digital asset question on page one of the 1040 gets answered yes.

Frequently asked

Quick answers on this topic.

Is crypto tax-loss harvesting legal, or will it trigger an IRS audit?

It's legal under current law. IRC §1091 applies to stock or securities, crypto is property under Notice 2014-21, and a properly reported loss on Form 8949 is an ordinary use of the rules, not a shelter. The audit exposure concentrates in same-second rebuys, where the IRS can argue the sale lacked economic substance under §7701(o). Waiting out some real market movement, or rotating into a different asset, removes most of that argument.

What happens to my cost basis when I buy the crypto back?

The repurchased coins take a basis equal to what you paid for them, and the holding period starts over from the repurchase date. There's no basis adjustment like a stock wash sale, because no loss was disallowed. That means the deduction is real today, and if the price recovers, the same dollars come back as gain when you eventually sell, short-term gain if you sell within a year of the rebuy.

How much crypto loss can I deduct against my W-2 income?

Capital losses first offset your capital gains with no dollar limit, including gains from stock and RSU sales. Beyond that, §1211(b) allows up to $3,000 per year against ordinary income like wages, or $1,500 if married filing separately, and §1212(b) carries the rest forward indefinitely. A $50,000 crypto loss with no gains to absorb it takes 17 years to use at $3,000 a year, which is why harvesting is most valuable in a year with big gains.

Does the wash sale rule apply to bitcoin ETFs like IBIT?

This one is genuinely unsettled. Spot bitcoin ETFs are structured as grantor trusts, so the tax law arguably looks through the shares and treats you as owning bitcoin, which is property outside §1091. But brokers report ETF shares as securities on Form 1099-B and flag wash sales on them, and the IRS has issued no guidance either way. If you're harvesting ETF losses rather than coin losses, the conservative play is to treat the 61-day window as applying.

Will the crypto wash sale loophole close retroactively for 2026?

It hasn't as of July 2026, but the risk is written into the pending bill. S. 2207, introduced July 3, 2025, applies its wash sale rule to tax years beginning after December 31, 2025, which would cover all of 2026 if enacted as drafted. Congress usually moves effective dates forward to enactment, and retroactive loss disallowance is rare, so I'd call the retroactive scenario unlikely but not impossible. Harvests completed before any enactment date that survives markup are the safest.

Wage and withholding planning

Squaring the withholding before the return is due.

Two W-2 jobs, a midyear job change, or a working spouse stack income in ways no single W-4 sees, which is how an over-withheld Social Security credit ends up sitting next to an underpayment penalty. We reconcile the wages, claim the excess Social Security credit, and reset the withholding, so the surprise lands in the plan instead of on the return.
