Crypto Wash Sale Rule: The Gap and How Long It Lasts

TLDR

The wash sale rule (IRC §1091) says you cannot sell a losing stock and buy it right back within 30 days and still claim the loss. That rule only applies to “stock or securities.” Cryptocurrency is treated as property, per IRS Notice 2014-21, not a security. So as of

August 2026, the wash sale rule does not apply to direct crypto trades

. You can sell Bitcoin at a loss and buy it back the same day and still claim the loss. This is a real, current rule, not a rumor. But two bills sit in Congress right now that would close this gap, and neither has passed. If you hold a crypto ETF or a crypto stock instead of the coin itself, the wash sale rule already applies to you.

In this guide, you’ll learn:

Why crypto sits outside the wash sale rule when stocks do not
The exact line between “still exempt” (direct crypto) and “already covered” (crypto ETFs and crypto-linked stocks)
What two pending bills in Congress would change, and why neither is law yet
Why the economic substance doctrine is a real limit even where the wash sale rule is not
A full worked example showing this is a timing benefit, not free money
What changes for you the day this gap closes

#The current rule, stated plainly

As of August 2026, if you sell a cryptocurrency at a loss and buy the same coin back a minute later, the wash sale rule does not block your loss. You can claim it on your tax return this year.

That is the current law. It is not a gray area, and it is not aggressive tax planning. It comes from reading the actual text of the wash sale statute next to how the IRS classifies crypto.

#Why the gap exists: two rules that don’t overlap

Two pieces fit together to create this gap.

#Piece 1: The wash sale rule only covers “stock or securities”

IRC §1091 disallows a loss when you sell a stock or security at a loss and buy the same or a “substantially identical” one within 30 days before or after the sale. That is a 61-day window in total: 30 days before the sale, the sale date, and 30 days after.

The statute’s language matters here. It names “stock or securities.” Congress wrote §1091 decades before crypto existed, aiming at the stock market. It was never written with digital assets in mind.

#Piece 2: The IRS classifies crypto as property, not a security

IRS Notice 2014-21, issued in 2014, was the first formal IRS guidance on virtual currency. It states plainly that “virtual currency is treated as property for U.S. federal tax purposes.” Not a security. Not a currency. Property, the same broad tax category that covers real estate, art, and collectibles.

Because §1091 names “stock or securities” and the IRS puts crypto in the “property” bucket, the wash sale rule’s own language does not reach it. No amendment has changed that as of this writing.

#Where the gap does NOT apply: crypto ETFs and crypto stocks

This is the part people get wrong most often, and it is worth being exact about it.

The wash sale rule still fully applies the moment you are holding a security, even one tied to crypto:

Spot Bitcoin and Ether ETFs (funds that hold the coins directly) are shares of a registered fund. Shares are securities. If you sell your ETF shares at a loss and buy the same ETF back within the 61-day window, the wash sale rule blocks the loss, exactly like it would for any stock ETF.
Crypto mining and exchange stocks (public companies whose business is crypto-related) are ordinary corporate stock. Selling and rebuying those triggers the wash sale rule the same as any other stock.
The underlying coin itself, bought and sold directly on an exchange or in a wallet, is property. That is the part the wash sale rule does not reach today.

Wash sale rule applicability, by what you actually hold
	Direct crypto (BTC, ETH, etc.)	Spot crypto ETF shares	Crypto-related stock
IRS classification	Property (Notice 2014-21)	Security (fund share)	Security (corporate stock)
Wash sale rule applies?	No, as of Aug 2026	Yes	Yes
Same-day repurchase after a loss sale	Loss allowed	Loss disallowed if within 61-day window	Loss disallowed if within 61-day window

So a client who sells Bitcoin at a loss and buys it back the next day keeps the loss. A client who does the same thing with IBIT (a spot Bitcoin ETF) does not.

#What’s pending in Congress, and why “pending” means “not yet the rule”

Two bills currently sit in Congress that would close this gap. As of August 2026, neither has been enacted. Both are proposals, not law.

The Digital Asset PARITY Act, introduced by Reps. Max Miller and Steven Horsford, would apply the stock-market wash sale rule to crypto directly, forcing a 30-day wait before you could repurchase and still claim a loss. In exchange, the proposal would defer tax on staking and mining rewards until you sell them, and add a small exemption for everyday crypto payments.

The Applying Existing Tax Anti-Abuse Rules to Digital Assets Act, introduced by Rep. Jodey Arrington, takes a narrower approach: it would simply extend the existing wash sale rule to cover digital assets, closing the gap directly.

Neither bill has passed the House, passed the Senate, or been signed into law. The One Big Beautiful Bill Act (OBBBA), the major 2025 tax legislation, did not include a crypto wash sale provision, so it left this gap untouched.

#Timing benefit, not permanent savings

Here is the part that gets lost in “loophole” framing: using this gap does not make your tax bill smaller in the long run. It moves the tax bill to a later year. Your cost basis carries forward either way.

Worked example.

Say you bought 1 Bitcoin for $70,000. It is now worth $55,000. You are considering selling to realize the loss, then buying it right back.

Without the sale:

Cost basis: $70,000
Unrealized loss: $15,000 (not usable on your return until you sell)

With the sale and same-day repurchase:

You sell 1 BTC for $55,000, realizing a $15,000 capital loss this year
You immediately buy 1 BTC back for $55,000
Because crypto is not subject to the wash sale rule, the $15,000 loss is allowed
Your new cost basis in the repurchased Bitcoin is $55,000, not $70,000

If you have $15,000 of capital gains elsewhere this year, that harvested loss offsets them dollar for dollar. If you do not have offsetting gains, up to $3,000 of the loss offsets ordinary income this year, and the rest carries forward under IRC §1212(b) (see the full mechanics in our tax-loss harvesting guide).

But your cost basis dropped from $70,000 to $55,000. If Bitcoin recovers to $80,000 and you sell later, your taxable gain is now $25,000 ($80,000 minus your new $55,000 basis) instead of $10,000 ($80,000 minus the original $70,000 basis). You already used $15,000 of that gain as a deduction this year. The math evens out. You did not make $15,000 disappear. You moved it from a future gain into a current-year loss, which is valuable because of when you use it, not because you avoided tax on it forever.

$15,000

Loss claimed this year

Sale at $55,000, basis $70,000
$55,000

New cost basis

After same-day repurchase
$0

Wash sale disallowance

Property, not a security, IRC §1091 does not apply

Illustrative example. Basis carries forward under IRC §1012; the harvested loss reduces a future gain by the same amount it reduces this year's income.

#The economic substance doctrine is a real limit, even here

The absence of a wash sale rule for crypto does not mean every same-day sell-and-rebuy is automatically bulletproof. The economic substance doctrine, codified at IRC §7701(o), lets the IRS disregard a transaction that has no meaningful economic effect beyond generating a tax benefit.

For a genuine sale and repurchase of crypto at the market price, with real money changing hands and real market risk during the (even brief) gap between the trades, this is not typically a concern. You genuinely sold an asset at its market price and genuinely bought it back at a (possibly different) market price. That is a real transaction with real economic substance, just one that happens not to trigger a rule that exists for stocks.

Where this gets riskier is a rapid pattern of trades structured purely to generate losses with no real change in market exposure or economic risk, especially across related accounts or with pre-arranged repurchase terms. The IRS has broad authority to look past form and examine substance when a transaction’s only purpose is a tax result. Document a real sale at market price, not a scripted round-trip with no price risk in between.

#What actually changes for you if this gap closes

If either pending bill becomes law, here is what would likely change for crypto held directly:

A 30-day (or similar) waiting period would apply before you could repurchase the same crypto and still claim the loss, mirroring the stock rule today
Existing tax-loss harvesting strategies built around crypto’s current exemption would need to shift to a “wait and rebuy a correlated asset” approach, the same playbook already used for stocks (see our tax-loss harvesting guide for how that works)
Effective date matters. Watch for whether a future law applies prospectively (new sales only) or covers the full tax year in which it passes. This has differed across past tax legislation and materially changes whether harvesting late in a year is safe.

We track this actively because it moves fast once it moves. If you are planning around this exemption, confirm the current law before you file, not when you first read this article.

#Common questions

Can I sell Bitcoin at a loss and buy it back the same day right now? As of August 2026, yes. The wash sale rule under IRC §1091 applies to stock and securities, and the IRS treats crypto as property under Notice 2014-21, so the rule does not currently reach direct crypto sales. Confirm this is still current law before you rely on it, since bills to change it are actively pending in Congress.

Does this apply to NFTs too? NFTs are also treated as property, not securities, so the same reasoning applies. There is added complexity around whether an NFT and a “substantially identical” NFT could even exist, since most NFTs are unique by design. See our NFT tax treatment guide for the broader picture.

What about a spot Bitcoin ETF like IBIT? Different answer. ETF shares are securities. If you sell IBIT at a loss and buy it back within 30 days, the wash sale rule applies exactly like it would for any stock ETF, and the loss is disallowed until you sell the replacement shares in a clean transaction.

Is this the same as the “crypto wash sale loophole” people talk about online? Yes, this is that gap. We are simply describing it precisely: it exists because of how two specific rules interact, it has a real legal basis, and it is not guaranteed to last.

Will this change retroactively if a bill passes? Unclear, and it depends entirely on the bill’s effective date language. Past federal tax changes have used both prospective and full-year effective dates. Don’t assume either direction. Check the specific bill’s text once (and if) it passes.

Do I still need to track cost basis carefully if I use this strategy? Yes, and if anything, more carefully. Every sale and repurchase changes your cost basis. If you harvest losses repeatedly across a volatile year, you can end up with a stack of lots at different basis amounts. Clean wallet and exchange reconciliation is what keeps this from turning into a mess at filing time.

Does the IRS see these trades even though the wash sale rule doesn’t apply? Yes. Centralized exchanges issue Form 1099-DA reporting your digital asset transactions to the IRS starting with the 2025 tax year. The IRS can and does match your return to those forms. Report every sale and repurchase accurately, even though the loss is currently allowed.

Crypto tax rules move fast, and this is one of the areas most likely to change without much warning. If you have meaningful crypto activity and want your tax-loss harvesting approach checked against current law before you file, not after, a Tax Discovery call is the right next step. We also handle the reconciliation work this strategy depends on through crypto bookkeeping.
