Does the Wash Sale Rule Apply to Crypto in 2026?
No. As of 2026, the wash sale rule does not apply to ordinary cryptocurrency. IRC §1091 disallows a loss only when you sell "stock or securities" at a loss and acquire substantially identical stock or securities within 30 days. The IRS has treated convertible virtual currency as property since Notice 2014-21, and property is not a security. That single classification is why crypto sits outside the wash sale rule.
The practical result: you can sell Bitcoin or Ether at a loss on December 30, claim the capital loss, and buy the same coin back on December 31. With stocks, that same move would disallow the loss. With crypto, under current law, it does not.
This post focuses narrowly on the wash sale question and the new Form 1099-DA reporting. For the broader picture, see our 2026 crypto tax guide and our explainer on Form 1099-DA broker reporting.
How the Wash Sale Rule Actually Works
The wash sale rule exists to stop investors from claiming a paper loss while keeping the same economic position. It works like this:
- You sell a security at a loss.
- Within 30 days before or after that sale (a 61-day window), you buy a substantially identical security.
- The loss is disallowed for the current year.
- The disallowed loss is added to the cost basis of the replacement security, and the holding period carries over.
The loss is not erased. It is deferred until you finally sell the replacement position in a transaction that is not itself a wash sale. The rule simply prevents you from booking the deduction now while staying invested.
Why Crypto Escapes the Wash Sale Rule
The entire wash sale framework hangs on the words "stock or securities" in §1091. Cryptocurrency does not fit that definition under federal tax law.
Because the rule does not apply, crypto investors keep a flexibility that stock investors lost decades ago: the ability to harvest a loss without giving up their position for a month.
What Form 1099-DA Box 1i Really Means
Here is where confusion takes hold in 2026. Form 1099-DA, the new broker reporting form for digital assets, is modeled on Form 1099-B for securities. That means it carries the same line items, including a wash sale box.
Key Boxes on Form 1099-DA
ReferenceThe relevant boxes for a sale are:
- Box 1f: Gross proceeds from the sale
- Box 1g: Cost basis of the digital asset sold
- Box 1i: Wash Sale Loss Disallowed
For ordinary cryptocurrency, Box 1i should be blank or zero, because the wash sale rule does not apply. A nonzero amount in Box 1i means the broker treated the position as a security.
The problem is that the box exists at all. Taxpayers and some tax software see "Wash Sale Loss Disallowed" on a crypto form and assume the rule now applies to their coins. It does not. The box is on the form to handle the narrow categories that genuinely are securities, and to be ready if the law changes later.
Watch for Incorrect Box 1i Entries
CautionIf a broker reports a wash sale disallowance in Box 1i for ordinary cryptocurrency, that is almost certainly a reporting error. Do not silently accept a disallowed loss you are entitled to claim. Reconcile the 1099-DA against your own records and correct the entry on Form 8949 if needed.
Tokenized Securities: The One Case That Triggers Box 1i
There is a real exception. Some digital assets are not ordinary crypto at all. They are tokenized securities, meaning blockchain-based tokens that represent stock or other instruments that are securities for tax purposes.
When a digital asset is also a security, the wash sale rule applies to it the same way it applies to a share of stock. A loss on a tokenized security repurchased within the 61-day window is disallowed, and that disallowance is exactly what Box 1i is designed to report. The disallowed loss is then added to the basis of the replacement tokens.
So the rule of thumb for 2026 is simple. Ordinary crypto (Bitcoin, Ether, most coins and NFTs): no wash sale, Box 1i blank. Tokenized securities: wash sale applies, Box 1i may be populated.
Tax-Loss Harvesting With Crypto in 2026
The absence of a wash sale rule makes crypto unusually friendly to loss harvesting. The mechanics:
- Identify positions held at an unrealized loss.
- Sell to realize the capital loss.
- Rebuy the same asset immediately if you want to keep the exposure.
- Use the loss to offset capital gains, then up to $3,000 of ordinary income, carrying the rest forward.
Harvest Crypto Losses the Right Way
CalculationA simple example:
- You bought 1 ETH for $4,000.
- ETH is now worth $2,500, an unrealized loss of $1,500.
- You sell the 1 ETH and immediately rebuy 1 ETH at $2,500.
- You report a $1,500 capital loss for the year and still hold 1 ETH.
With a stock, step 3 would disallow the loss. With crypto under 2026 law, the loss stands.
One caution. Even though §1091 does not apply, a transaction should still have economic substance. A sale and rebuy that genuinely moves at market prices, with real settlement and accurate records, is sound. Manufactured round trips designed purely to create a deduction with no economic reality can draw scrutiny under broader doctrines. For most investors, a clean sale and repurchase at fair market value is exactly the kind of planning the current rules allow.
Could the Rule Change?
It might. Lawmakers have repeatedly tried to close the crypto loss-harvesting window. Proposals to extend the wash sale rule to digital assets appeared in draft tax legislation as far back as 2021 and resurfaced in 2024 and 2025. None has been enacted as of 2026.
The takeaway for planning is twofold. First, the strategy is legal today, so there is no reason to forgo it out of caution. Second, the door could close in a future year, often with little notice, so treat any given year's harvesting opportunity as something to use rather than defer indefinitely.
How to Report Crypto Losses Correctly in 2026
Reporting starts with reconciliation. Brokers now send Form 1099-DA, and 2026 transactions include cost basis, but the figures are only as good as the broker's records. Self-custody transfers, wallet-to-wallet moves, and assets bought before broker reporting began can all produce gaps.
Steps for an accurate return:
- Gather every Form 1099-DA and match it to your own transaction log.
- Confirm Box 1g basis is correct, especially for assets transferred between platforms.
- Confirm Box 1i is blank for ordinary crypto. Question any nonzero amount.
- Report each disposition on Form 8949 and carry totals to Schedule D.
- Apply losses against capital gains first, then up to $3,000 against ordinary income, and carry forward the remainder.
Accurate reporting matters more in 2026 than ever, because the IRS now receives a parallel data feed from brokers. A return that does not reconcile to the 1099-DA data is a common audit trigger.
Planning Considerations
Harvest before year end, not after. Losses are claimed in the year the sale settles. A loss you intend to take in December must actually be executed in December.
Keep your own records regardless of the 1099-DA. Broker basis can be wrong or incomplete. Your contemporaneous log is the authority if the IRS questions a figure.
Separate ordinary crypto from tokenized securities. If you hold tokenized stock or security-like tokens, the wash sale rule does apply to those positions. Track them separately so you do not accidentally claim a disallowed loss.
Plan for a possible rule change. If wash sale legislation for digital assets advances, the planning calculus shifts immediately. Stay current so you can act before an effective date rather than after.
