Lawmakers on Capitol Hill are moving to close a tax loophole that many cryptocurrency holders use to offset gains — a change that could raise billions for the Treasury and alter tax planning for retail and institutional investors. With proposals gaining support from both parties, the issue has shifted from niche tax debate to a wider fiscal and regulatory conversation.
How the loophole works
Under current rules, the government treats most cryptocurrencies as property rather than securities. That classification means digital coins are not covered by the long-standing wash sale rule, which limits the ability of investors to claim a tax deduction for a loss if they buy back a substantially similar security within 30 days.

Without that restriction, an investor can sell a cryptocurrency at a loss to realize the tax benefit and then immediately repurchase the same coin — effectively preserving their market exposure while taking a deduction. Accountants and tax advisers say this form of tax-loss harvesting has become common practice in the crypto space.
What lawmakers are proposing
In June, Rep. Jodey Arrington (R-Texas) introduced the Applying Existing Tax Anti-Abuse Rules to Digital Assets Act, which would explicitly bring crypto transactions under the wash sale framework. The move follows earlier Democratic efforts and a Treasury Department estimate that applying wash sale rules to digital assets could boost federal revenue by nearly $24 billion over 10 years.
Tax policy experts note the bill’s sponsorship by a Republican signals growing bipartisan interest. Colin Wilhelm, who leads tax legislative affairs at Grant Thornton, described the proposal as a sign of momentum around digital-asset tax reforms within tax-writing committees.
Why this matters now
Many retail investors who purchased crypto over the past year or two are holding positions that are currently underwater. With prices down — Bitcoin has fallen roughly half its value since October 2025 — the opportunity to lock in losses and offset other gains has become especially attractive.

Extending wash sale rules to digital assets would remove that tax advantage, potentially changing portfolio and tax strategies for a broad swath of crypto holders and traders. For federal policymakers, it also represents a relatively straightforward revenue measure at a time when budget items that raise money can be politically valuable.
Who would and wouldn’t be affected
The impact depends on how someone holds crypto.
- Investors who own coins directly on exchanges or in private wallets are generally treated as holding property and would, under the proposed change, lose the ability to claim losses while immediately repurchasing the same asset.
- Holders of crypto exchange-traded funds and other regulated investment vehicles — which are treated as securities — already fall under wash sale rules and must follow the 30-day window.
- Traders may try to work around new rules by switching between different cryptocurrencies that are argued to be not “substantially similar.” Tax advisers point out that differences between coins could strengthen such arguments, much like selling one class of a company’s stock and buying a different class.
Political and practical outlook
Support for the change spans both sides of the aisle: Rep. Ron Estes (R-Kansas) told the House Ways and Means Committee that aligning tax treatment for crypto with other assets would create clarity and fairness. Still, experts caution that passage this year is unlikely given the congressional calendar and approaching midterm elections.
Even if immediate enactment is doubtful, the bills serve as a marker of shifting priorities. They also reflect a broader push in the Senate for separate, more comprehensive crypto rules — including measures that would limit certain federal actions around digital tokens.
For investors and advisers, the development signals that tax planning assumptions about crypto may not be stable. If lawmakers act, bookkeeping, trading practices and year-end tax strategies could all require revision.
Key takeaways
- Wash sale protections currently do not apply to most cryptocurrencies because they are classified as property, not securities.
- Legislation introduced by Rep. Jodey Arrington would extend wash sale rules to digital assets and is drawing bipartisan attention.
- The Treasury estimates the change could raise about $24 billion over a decade, making it a notable budget item.
- Crypto ETFs are generally already subject to wash sale rules; directly held coins are not.
- Even if passage this year is unlikely, the proposals indicate growing political will to tighten crypto tax rules — a development investors should monitor.
Tax attorneys and accountants say individuals with significant crypto holdings should consult their advisers as the legislative picture evolves, since technical details of any final law will determine how strictly wash sale limits apply to different trading strategies.
