| Situation | Current position | Planning use |
|---|---|---|
| Sell crypto at a loss and buy the same token back | Possible the same day or even the same hour, because the wash sale rule is not extended to crypto | You can realize the loss without sitting out of the market. Plan the rebuy deliberately and record both trades. |
| Scope of the wash sale rule | Applies explicitly to stocks and securities, not to cryptocurrency under current law | Do not apply stock-style waiting rules by reflex, and do not treat the gap as permanent. |
| Proposed legislation | A bill to extend the rule to digital assets has been proposed in Congress, and any change could carry retroactive or short-notice effective dates | Recheck the status before you harvest losses late in the year. |
| Economic substance | A potential risk that losses are not deductible against gains if the trade lacks economic purpose | Keep a reason for the trade that goes beyond the tax result. |
| If the rule did apply (securities) | The loss is disallowed and added to the cost basis of the replacement | Shows what a rebuy would cost you if the rules were extended. |

Does wash sale apply to crypto? Not under current law as described by tax guidance: the rule covers stocks and securities, so you can sell crypto at a loss and rebuy immediately, though proposed legislation could change that.
This guide sits within our crypto guides for beginners. It starts with what the answer changes for your trades, then explains the rule itself and where the law stands.
What the rule’s absence means for a loss sale
The wash sale rule does not currently reach bitcoin or other tokens, so selling at a loss and buying back straight away is not blocked by it. Parikh Financial states that the rule applies explicitly to stocks and securities but does not extend to cryptocurrency. That is the central US answer, and it is what separates crypto loss harvesting from the same move in a brokerage account.
Selling at a loss and rebuying immediately
An investor who sells bitcoin below the purchase price can, under current treatment, buy the same token back the same day or even the same hour. The practical effect is that the position you wanted to keep is restored while the loss is still on the books. In a stock account, the rule would instead disallow that loss.
The rebuy does not need a calendar. You do not have to count days, match lots against a window or track a replacement purchase made before the sale. That makes the process simpler, but it puts more weight on your own judgement about whether the trade is sound.
Where risk remains
Koinly points out that, even without a wash sale rule for crypto, there is a potential risk that such losses would not be deductible against gains. The concern is economic substance: a transaction that has no purpose beyond generating a tax loss may be challenged. The rule is not the only barrier a loss can face.
This risk shapes how you should behave. A sale that reflects a real change in view, a rebalance or a defined strategy is easier to defend than a same-minute sell and rebuy at identical size. Neither source says that quick rebuys are prohibited, so treat this as a reason to document your intent rather than a ban.
Choosing how to harvest a loss
The right approach depends on how much you value staying invested, how cautious you want to be and how much you expect the law to move. The current gap in the rule gives you room to choose, and each path has a clear cost.
- Rebuy immediately. This suits someone who wants to keep exposure and accepts the economic substance risk. Write down why you made the sale, and keep both transaction records together.
- Wait 30 days. Crypto.com’s help guidance suggests waiting 30 days after the sale date before making another investment, as the cautious approach for securities. For crypto it suits anyone who wants the sale to look the same under stock-style rules and who is willing to be out of the market during that time.
- Rotate into a different asset. If you are no longer convinced by the position you sold, researching alternatives is a more natural reason for the trade than a pure rebuy. Our piece on how to find new crypto coins covers that research.
- Hold off while legislation is live. If a bill is moving, a late-year harvest carries more uncertainty, because proposed changes could take effect with short notice or retroactively.
Waiting does not change the tax outcome you are entitled to today. It buys protection against rule changes and challenges, at the price of market exposure.
Records to keep for crypto losses
A loss is only as useful as the history behind it. Keep the date and time of each sale, the amount and proceeds, the cost you originally paid, and the date and size of any rebuy of the same token. If you trade on more than one platform, keep those histories side by side.
Account separation matters because Crypto.com’s guidance notes that the IRS may consider transactions across multiple accounts, including other brokerages, when it determines wash sales. Records that show every account in one timeline are therefore easier to defend than a single exchange export.
Exchange exports are the starting point, and portfolio trackers can help during the year. Koinly notes that such tools let investors view realized and unrealized gains and losses throughout the financial year. Seeing realized losses before year-end tells you whether a harvest is worth doing at all.

How the wash sale rule works for securities
The wash sale rule explicitly applies to stocks and securities but does not extend to cryptocurrency under current law. Under the rule, a loss is disallowed if you buy the same or a substantially identical security within 30 days before or after the sale date, as Crypto.com’s help centre summarizes. Koinly adds that, counting the days after the sale and the days before it, the full window covers 61 days.
The disallowed loss is not simply lost. It is added to the cost basis of the replacement investment, and the holding period of what you sold is added to the holding period of the new investment. Koinly illustrates this with a securities-style example in which the disallowed loss increases the adjusted basis of the replacement shares.
For crypto, this example shows only what you would face if the rule were extended. Because the rule currently does not reach cryptocurrency, the loss you realize on a sale is not pushed into the replacement’s basis.
Legislation and the current status
Legislation to extend the wash sale rule to digital assets has been proposed in Congress, but the fetched source describes it as proposed rather than enacted. The status today is therefore that crypto sits outside the rule, with a live possibility that this changes.
Parikh Financial cautions that proposed legislation could change the rules, potentially with retroactive or short-notice effective dates. This is the main reason to avoid building a long-term strategy around the gap. A tactic that is clean this year could be disallowed in a later one, and a plan that works either way, such as documented trades with sound reasons, ages better.
When you want to check the current position, read the statute text and the IRS guidance on digital assets directly, and look at the status of any bill before acting. Rules on crypto are changing quickly, so a source dated before the latest session may be out of date.
Frequently asked questions
Does the wash sale rule apply to gains?
No. The rule applies only to losses, so a gain on a sale is unaffected by buying the same asset again.
Does the holding period change after a wash sale?
For securities, yes. The holding period of the investment you sold is added to the holding period of the replacement. That treatment is part of the rule, and it does not currently apply to crypto.
Do trades on other exchanges matter?
They can. Crypto.com’s guidance says the IRS may consider transactions across multiple accounts, including other brokerages, when determining wash sales. Keep all platforms in one record.
Is it safe to rely on the current gap?
It is the current treatment, but not a guarantee. A bill has been proposed, and a change could take effect retroactively or at short notice, so document each trade and recheck the law before year-end.
