For years, U.S. crypto investors have utilized a tax strategy unavailable to stock traders: selling digital assets at a loss and immediately repurchasing them to lower their tax bills. This "loophole" exists because crypto is treated as property, not securities. However, proposed legislation in Congress aims to close this gap, potentially changing crypto tax-loss harvesting forever.

What is the Crypto Wash Sale 'Loophole'?

The wash sale rule, detailed in Section 1091 of the Internal Revenue Code, is a long-standing anti-abuse provision in U.S. tax law. It prevents investors from claiming a capital loss on the sale of an asset if they purchase the same or a "substantially identical" asset within 30 days before or after the sale. This 61-day window is designed to stop investors from creating artificial losses while maintaining their economic position.

Currently, IRC §1091 explicitly applies only to "stock or securities." This is a critical distinction for crypto investors. According to foundational guidance from IRS Notice 2014-21 (March 25, 2014), the IRS treats virtual currencies as property for federal tax purposes. Because digital assets are not classified as securities, the wash sale rule does not apply to them.

This has created what many call the "crypto wash sale loophole." A trader can sell Bitcoin at a loss on December 30th to offset capital gains, and then buy back the same amount of Bitcoin on December 31st. They successfully "harvest" the tax loss to reduce their taxable income for the year without meaningfully exiting their investment position. This strategy is not permissible for someone trading Apple stock.

New House Proposals: Applying Anti-Abuse Rules to Digital Assets

The landscape of crypto taxation may be on the verge of a significant shift. reportedly, in early June 2026, the House Ways & Means Committee released several draft bills aimed at clarifying digital asset taxation. One of the most impactful proposals is H.R. 9172, titled the "Applying Existing Tax Anti-Abuse Rules to Digital Assets Act"

As described in a document from the Joint Committee on Taxation for a hearing scheduled on June 9, 2026, this bill seeks to bring tax parity between digital assets and traditional financial instruments. It is crucial to understand that this is proposed legislation and reportedly has not been enacted into law as of June 2026

The draft legislation has two primary objectives:

Extend the wash sale rule under IRC §1091 to cover digital assets.
Extend the constructive sale rule under IRC §1259 to cover digital assets.

If passed, these changes would eliminate some of the most significant differences in tax treatment between crypto and securities, fundamentally altering common tax planning strategies for crypto investors.

How the Proposed Crypto Wash Sale Rule Would Work

The core of the proposal is a simple but powerful change to the existing law. H.R. 9172 suggests amending IRC §1091 by replacing the term "stock or securities" with "specified assets."

According to the bill text, a "specified asset" would be defined as:

Any stock or security.
Any digital asset (with certain exceptions, discussed below).
Any contract or option to acquire or sell any of the above.

This change would directly place most cryptocurrencies, like Bitcoin and Ether, under the purview of the wash sale rule. If an investor sells BTC at a loss, they would have to wait more than 30 days to repurchase it to claim that loss on their tax return. If they repurchase within the 61-day window, the loss is disallowed and instead added to the cost basis of the newly acquired BTC.

Comparison: Current vs. Proposed Wash Sale Rule

Feature	Current Law (IRC §1091)	Proposed Law (H.R. 9172)
Assets Covered	Stock or securities	"Specified assets," including stocks, securities, and digital assets.
Applies to Crypto?	No. Crypto is property.	Yes. Digital assets are explicitly included.
61-Day Window	Yes (30 days before/after sale)	Yes (30 days before/after sale)
Effect on Trader	Crypto traders can sell and immediately rebuy to harvest losses.	Crypto traders must wait 31+ days to rebuy to claim a loss.

A particularly important detail in the proposed legislation is its treatment of "substantially identical" assets. The bill clarifies that a tokenized or wrapped digital asset would be treated as substantially identical to any asset to which it is "economically equivalent." This could have far-reaching implications for DeFi, where assets like Wrapped Ether (WETH) are used interchangeably with Ether (ETH). The IRS would likely need to issue further guidance on what constitutes economic equivalence in the complex crypto ecosystem.

Navigating these potential changes requires robust record-keeping. Platforms like dTax are designed to import transactions from hundreds of exchanges and wallets, automatically calculating the acquisition cost and proceeds for every trade. Should these new rules be enacted, such tools would be invaluable for identifying transactions that could trigger a wash sale, helping users and their tax advisors stay compliant.

Understanding the Proposed Constructive Sale Rule for Crypto

The second major component of H.R. 9172 is the application of constructive sale rules to digital assets. The constructive sale rule, found in IRC §1259, prevents investors from using financial derivatives to lock in gains on an appreciated asset without actually selling it and triggering a taxable event.

Currently, if you own appreciated stock, you can't enter into a "short-against-the-box" transaction (i.e., shorting the same stock you own) to eliminate your risk and defer taxes. Doing so is treated as a "constructive sale," and you must recognize the capital gain as if you had sold the stock.

The proposed bill would amend IRC §1259 to include "digital asset" as an appreciated financial position. This means that if an investor holds an appreciated crypto asset (e.g., a large amount of ETH purchased years ago) and enters into a transaction that substantially eliminates their risk and opportunity for gain (like shorting ETH perpetual futures), it could be treated as a constructive sale. This would force the investor to recognize and pay capital gains tax on their appreciated ETH immediately, even though they haven't sold the underlying spot asset.

Key Exemptions in the Draft Legislation

While the proposed rules are broad, the drafters included several important exemptions.

Qualified U.S. Dollar Stablecoins: The bill explicitly excludes "qualified U.S. dollar stablecoins" from the definition of both "specified asset" (for wash sales) and "digital asset" (for constructive sales). This means trading in and out of compliant stablecoins would not trigger these anti-abuse rules.
Mark-to-Market Assets: Transactions under Section 475, which allows certain traders to use mark-to-market accounting, are already excluded from the wash sale rules. This would likely continue.
De Minimis Fees: Proposed legislation elsewhere aims to create a de minimis exemption for gains from paying network transaction fees, which would also fall outside the wash sale rules.

One of the most discussed aspects of the bill is its proposed effective date. According to analysis from legal experts at Steptoe, the provisions would apply to dispositions and constructive sales occurring after the date the bill is introduced. This raises concerns about retroactivity, as a sale made the day after introduction could be deemed a wash sale if the investor had purchased the same asset within the previous 30 days.

Impact on Crypto Traders and Tax-Loss Harvesting

If enacted, the "Applying Existing Tax Anti-Abuse Rules to Digital Assets Act" would mark the end of an era for crypto tax strategy in the United States.

The primary impact would be the elimination of the most popular form of crypto tax-loss harvesting. Traders would no longer be able to sell and instantly repurchase assets to book a loss. They would need to adopt strategies similar to stock traders, such as waiting 31 days to re-enter a position or selling one asset (like BTC) and buying a different, non-substantially-identical asset (like ETH) to maintain market exposure.

This introduces significant complexity. The "substantially identical" and "economically equivalent" standards are not clearly defined for the digital asset space.

Is ETH substantially identical to a liquid staking token like stETH?
Is a tokenized representation of a stock on one blockchain identical to the actual stock on Wall Street?
Are two different yield-bearing stablecoin tokens economically equivalent?

These questions will require extensive guidance from the IRS. The increased complexity underscores the need for sophisticated tracking. The AI-assisted classification features in crypto tax software can help categorize thousands of transactions, but with rules this nuanced, human review by a qualified professional will become more critical than ever.

How to Prepare for Potential Changes

While these rules are still proposals, proactive investors can take steps now to prepare for a more complex tax environment.

Meticulous Record-Keeping is Non-Negotiable: The single most important step is to maintain a complete and accurate record of every single crypto transaction. This includes the date, asset, quantity, cost basis, sale price, and associated fees for every trade, transfer, and swap.
Consolidate Your Data: Use a crypto tax platform to aggregate your transaction history from all your wallets and exchanges into one place. Getting your data organized now will make it far easier to analyze your tax position and adapt to any new legislation that may pass.
Review Your Trading Strategy: Consider how an active wash sale rule would affect your tax-loss harvesting plans. You may need to build in a 31-day waiting period for assets you wish to sell and repurchase.
Consult a Professional: The tax implications of these proposed rules can be complex. Discuss your specific investment portfolio and trading patterns with a tax professional who is knowledgeable about digital assets.

The legislative push to align digital asset taxation with traditional finance signals a maturing industry. While it may close popular loopholes, it also provides a clearer, more predictable regulatory framework for the future.

Frequently Asked Questions

When would the crypto wash sale rule take effect?

The crypto wash sale rule is part of a legislative proposal (H.R. 9172) and is not yet law. If the bill were to be passed as currently written, its provisions would apply to transactions that occur after the date the bill is formally introduced. This could create a look-back period, affecting sales made shortly after introduction if a repurchase was made in the 30 days prior.

Does the proposed wash sale rule apply to NFTs?

Yes, it appears so. The bill's definition of "digital asset" is broad: "any digital representation of value which is recorded on a cryptographically secured distributed ledger." This would almost certainly include non-fungible tokens (NFTs). The bill also has specific language about "tokenized digital assets" being treated as substantially identical to any asset they are economically equivalent to, which could directly apply to certain types of NFTs.

What is tax-loss harvesting?

Tax-loss harvesting is a strategy used to reduce capital gains taxes. It involves selling an investment that has decreased in value to realize a loss. This capital loss can then be used to offset capital gains from other investments. In the U.S., you can offset an unlimited amount of capital gains with capital losses, and then deduct up to an additional $3,000 of losses against your ordinary income per year.
