Crypto Wash Sale Rule 2026: Can You Still Sell and Rebuy?

You sold crypto at a loss. You want to buy it back. And you're wondering: is that allowed?

If you're in the US, the short answer is yes — for now. The IRS wash sale rule, which stops stock investors from selling at a loss and immediately repurchasing the same asset, does not currently apply to cryptocurrency. Crypto is classified as property under IRC §1091, not a security, so the 30-day wash sale restriction doesn't kick in.

That means you can sell Bitcoin at a loss on Monday, buy it back on Tuesday, and still claim the full capital loss on your tax return. It's one of the biggest tax advantages crypto has over traditional investments — and it's exactly why so many people are Googling it right now.

But the picture is more complicated than that one-liner suggests.

What is the wash sale rule?

The wash sale rule is an IRS rule designed to prevent investors from gaming the tax system. It says: if you sell a stock or security at a loss and buy a substantially identical asset within 30 days before or after the sale, you can't claim the loss on your taxes. The loss is "disallowed."

The logic is straightforward — you haven't actually changed your economic position. You still own the same thing. You just created a paper loss for tax purposes.

For stocks, this has been the law for decades. You sell Apple shares at a loss, buy them back two weeks later, and the IRS says: nice try, that loss doesn't count.

Why crypto is different (in the US)

The IRS treats cryptocurrency as property, not as a stock or security. The wash sale rule under Section 1091 specifically applies to "stock or securities." Since crypto doesn't fall into either category, the rule doesn't apply.

This creates an enormous tax planning opportunity. You can:

• Sell crypto at a loss to realise the capital loss
• Buy back the exact same token immediately
• Claim the full loss to offset other gains
• Continue holding your position as if nothing happened

This strategy is especially powerful when combined with tax loss harvesting — systematically selling losing positions to offset your winners.

Will the wash sale rule be extended to crypto?

Almost certainly — the question is when.

Congress has tried to close this gap multiple times. The Build Back Better Act in 2021 included language extending wash sales to digital assets. It didn't pass. The Lummis-Gillibrand Responsible Financial Innovation Act proposed the same thing. It stalled. New proposals in 2024 and 2025 again targeted the loophole.

In mid-2025, the White House published a 166-page report recommending crypto be treated as a distinct asset class subject to rules similar to securities — including wash sales. A Congressional Discussion Draft followed, explicitly proposing that wash sale rules apply to digital assets.

The direction is clear, even if the timeline isn't. No legislation has passed as of early 2026, but every new proposal gets closer. If you're aggressively harvesting crypto losses today, build your strategy assuming these rules will eventually apply.

The 1099-DA connection

Starting in 2026, the IRS Form 1099-DA requires exchanges to report your crypto transactions. Here's the detail most people miss: the form includes Box 1i — "Wash Sales Loss Disallowed."

The IRS has already built the reporting infrastructure for crypto wash sales. The box exists on the form. Exchanges are being told to track it. Even though the rule doesn't technically apply to most crypto yet, the machinery is in place.

For the 2025 tax year, exchanges aren't required to report cost basis, so this box may be largely empty. But for transactions starting January 1, 2026, exchanges must report basis for "covered" digital assets — and wash sale tracking comes with it.

If you received a 1099-DA with confusing numbers, the missing cost basis problem is likely making your wash sale situation even harder to untangle.

What about Bitcoin ETFs?

This is where things get genuinely murky. Spot Bitcoin ETFs (like BlackRock's IBIT) are structured as grantor trusts, which means shareholders are treated as owning the underlying Bitcoin — property, not a security.

However, many broker-dealers are reporting these ETF transactions on Form 1099-B and applying wash sale adjustments, treating them as securities. This creates a disconnect: the legal treatment may say "no wash sale" (property via grantor trust look-through), but your tax form says otherwise.

The IRS hasn't issued direct guidance on this specific point. If you're trading spot Bitcoin ETFs alongside direct Bitcoin, the interaction between the two gets complicated quickly. Conservative approach: treat them as potentially subject to wash sales until the IRS clarifies.

Country-by-country: where "wash sales" already apply

The US gets the headlines, but if you're filing in other countries, you may already have wash sale restrictions — they're just called different things.

🇬🇧 United Kingdom — Bed & Breakfasting Rule

HMRC has a 30-day matching rule that functions almost identically to a wash sale rule. If you sell crypto at a loss and repurchase the same token within 30 days, the loss is recalculated using the repurchase price — which effectively wipes out the loss.

There's also a same-day rule: any crypto bought and sold on the same day is matched first, before applying the 30-day rule.

Practical impact: UK crypto investors cannot do the "sell and immediately rebuy" strategy that US investors can. To harvest losses in the UK, you must either wait 31 days before repurchasing, or rotate into a different asset.

Some investors sell ETH and buy a similar but different asset (like SOL) to maintain market exposure during the 30-day window. This is legal, but carries market risk — the replacement asset may not track the same way.

🇨🇦 Canada — Superficial Loss Rule

Canada has a Superficial Loss Rule under Section 54 of the Income Tax Act. If you or an "affiliated person" (spouse, corporation you control) buys back the same property within 30 days before or after the sale, the loss is denied.

The denied loss isn't lost forever — it gets added to the cost basis of the repurchased asset, deferring it to a future sale. But it means the immediate tax benefit disappears.

Key difference from the US: Canada's rule uses "property" language, which clearly includes crypto. There's no ambiguity here — the superficial loss rule applies to cryptocurrency in Canada.

🇦🇺 Australia — Similar provisions

The ATO doesn't have a specific "wash sale" rule, but they can apply Part IVA — the general anti-avoidance provision — to schemes whose dominant purpose is obtaining a tax benefit. Selling and immediately repurchasing crypto purely for tax purposes could trigger this.

Australia also has integrity rules around related-party transactions and scheme arrangements. The ATO has flagged "asset wash sales" as an area of compliance focus.

Practical advice: Australian investors can generally harvest losses, but should avoid patterns that look purely tax-motivated with no genuine change in position. If you sell and repurchase within a short window repeatedly, you're asking for scrutiny.

🇩🇪 Germany — Different approach entirely

Germany doesn't have a traditional wash sale rule, but it has something potentially better for investors: the one-year holding rule (Haltefrist). If you hold crypto for more than one year, gains are completely tax-free.

The incentive structure here is different. Rather than harvesting losses aggressively, German investors often benefit more from holding through dips. Selling to harvest a loss resets your holding period when you repurchase, potentially costing you the tax-free treatment on the entire position.

How to handle wash sales properly in your tax return

Even if the wash sale rule doesn't apply to your crypto transactions, you still need clean records. Here's what creates problems at filing time:

Multiple exchanges and wallets. If you sell BTC on Coinbase at a loss and buy BTC on Kraken the same day, you need records showing both transactions. Without connecting the dots, a tax authority reviewing your 1099-DAs might see a repurchase and ask questions.

Cost basis tracking across platforms. Selling and repurchasing resets your cost basis to the new purchase price. If your records don't track this correctly, you'll misstate gains when you eventually sell for real.

Cross-asset swaps. If you sell ETH at a loss and buy stETH, are these "substantially identical"? In the stock world, substantially identical securities include options on the same stock. In crypto, there's no definitive guidance. Wrapped tokens, staking derivatives, and yield-bearing versions of the same asset are all grey areas.

Bot trading volumes. If you're running trading bots that execute hundreds of trades daily, you may have inadvertent wash sale patterns mixed in with legitimate trades. Untangling these requires proper reconciliation.

The smart approach for 2026

Whether or not the wash sale rule currently applies to your situation, here's what we tell our clients:

Keep impeccable records. Track every buy, sell, swap, and transfer with timestamps and cost basis. If wash sale rules are retroactively applied (unlikely but not impossible), or if you need to defend your positions in an audit, records are everything.

Don't be purely tax-motivated. The economic substance doctrine gives tax authorities a way to challenge transactions with no purpose other than tax reduction. If your trading pattern is clearly "sell, rebuy one minute later, repeat" — even in the US — you're increasing audit risk.

Understand your country's rules. US? You're clear for now. UK? 30-day rule applies. Canada? Superficial loss rule applies. Australia? Anti-avoidance provisions are a concern. Germany? Holding periods matter more than loss harvesting.

Get your data reconciled. The biggest problem isn't the wash sale rule itself — it's knowing what your actual gains and losses are in the first place. When your data is spread across 10 exchanges and 5 wallets, Koinly errors and missing cost basis create bigger problems than any wash sale.
