The Crypto Wash Sale Rule: Does It Apply?

As of the 2026 tax year, the wash sale rule does not apply to cryptocurrency. Because the IRS treats crypto as property rather than a security, you can sell a coin at a loss, claim that loss on your taxes, and buy the same coin back immediately — something stock investors can't do.

What is the wash sale rule?

The wash sale rule (Internal Revenue Code Section 1091) stops investors from claiming a tax loss on a security if they buy a "substantially identical" security within 30 days before or after the sale. The window is 61 days total: 30 days before the sale, the day of the sale, and 30 days after.

When a wash sale is triggered, you can't deduct the loss right away. Instead, the disallowed loss is added to the cost basis of the replacement shares, so you recover it later when you eventually sell for good. The rule exists to prevent people from selling purely to harvest a paper loss while keeping their position intact.

Why crypto is different

Section 1091 applies specifically to "stock or securities." The IRS classifies cryptocurrency as property, not a security — the same category as real estate or collectibles. Because a bitcoin or an ether isn't a stock or security under the tax code, the wash sale rule as written simply doesn't reach it. For a refresher on the property treatment that drives this, see how cryptocurrency is taxed.

That gap creates a real planning advantage. With stocks, harvesting a loss forces you out of your position for 31 days, exposing you to a price rebound. With crypto, you can realize the loss and re-enter the same asset in minutes, keeping your exposure while still booking the deduction.

How crypto tax-loss harvesting works

Tax-loss harvesting means intentionally selling assets that have dropped below their cost basis to generate capital losses. Those losses offset your capital gains, and if losses exceed gains, you can deduct up to $3,000 against ordinary income each year, carrying the rest forward to future years.

A simplified example:

• You bought 1 ETH for $4,000. It's now worth $2,500.
• You sell it, realizing a $1,500 capital loss.
• You immediately rebuy 1 ETH at $2,500 — your new cost basis.
• You still hold your position, and the $1,500 loss offsets gains elsewhere in your portfolio.

For stocks, that immediate rebuy would be a wash sale. For crypto, under current rules, it isn't.

Important caveats

The absence of a wash sale rule doesn't mean anything goes. Keep these in mind:

• The loss must be genuine. You need a real disposal at a real market price. Selling to yourself or to a related party doesn't work, and the IRS can challenge transactions that lack economic substance.
• Holding periods reset. When you rebuy, your holding period starts over. If the price climbs and you sell within a year, that gain is short-term and taxed at higher ordinary rates.
• Tokenized securities are different. If you hold something that's legally a security — such as a tokenized stock or certain security-token offerings — the wash sale rule can apply, because the underlying asset is a security regardless of how it's wrapped.
• Basis is now per-wallet. Starting in 2025, cost basis is tracked wallet-by-wallet rather than universally across all your accounts, which affects exactly which lots you're disposing of when you harvest.

Could the rule change?

Lawmakers have repeatedly proposed extending the wash sale rule to digital assets, and it's a well-known target for closing the "loophole." No such change is in effect for the 2026 tax year, but this is an area to watch — a future law could apply the 30-day window to crypto, potentially with little lead time. If you're relying on this strategy, treat it as current-year planning, not a permanent fixture.

Reporting your harvested losses

Every disposal — including a harvest sale — is a taxable event you report on Form 8949 and Schedule D, with each gain or loss flowing through. Since 2025, brokers issue Form 1099-DA for many centralized-exchange transactions, but the 1099-DA doesn't always capture your full cost basis, especially across multiple wallets or DeFi activity. You're responsible for accurate records. The same care applies if you're also earning crypto — staking rewards and other earned crypto are ordinary income, taxed separately from these capital gains and losses.
