Understanding the Wash Sale Rule in Today’s Crypto Landscape
The short answer is clear: as of tax years beginning after December 31, 2022, yes — the wash sale rule now applies to cryptocurrencies due to changes introduced by the SECURE 2.0 Act. While the traditional wash sale rule previously only covered securities like stocks and bonds, digital assets are now explicitly included under U.S. tax law.
This shift marks a pivotal moment for crypto investors who may have once viewed digital currencies as a tax-efficient asset class with unique advantages. No longer can you sell a cryptocurrency at a loss and immediately repurchase it to lock in a tax deduction without consequences.

What Is the Wash Sale Rule?
The wash sale rule is a regulation enforced by the IRS to prevent taxpayers from claiming artificial capital losses. According to this rule, if you sell or trade a security (or digital asset) at a loss and then buy a "substantially identical" asset within 30 days before or after the sale — a 61-day window — the loss is disallowed for tax purposes.
Instead of being deductible in the current year, the disallowed loss is added to the cost basis of the newly acquired asset. This defers the tax benefit until that asset is eventually sold in a non-wash-sale transaction.
For example:
- You sell 1 ETH for $2,800 after originally buying it for $3,500 (a $700 loss).
- Within 20 days, you repurchase 1 ETH for $2,900.
- The $700 loss cannot be claimed now.
- Your new cost basis becomes $3,600 ($2,900 purchase price + $700 disallowed loss).
This mechanism ensures investors can't manipulate their tax liabilities without altering their actual market exposure.
Why Cryptocurrency Was Once an Exception
Historically, the IRS classified cryptocurrencies as property, not securities, under Notice 2014-21. Because the wash sale rule applied only to securities, many investors assumed crypto trades were exempt. This created a widely exploited loophole: investors could sell crypto at a loss, claim the deduction, and rebuy almost instantly — effectively resetting their cost basis with no real change in portfolio position.
However, this advantage has been eliminated by legislative action.
The Impact of the SECURE 2.0 Act on Crypto Taxes
The SECURE 2.0 Act of 2022 amended Section 1091 of the Internal Revenue Code to expand the definition of assets subject to the wash sale rule. It now explicitly includes digital assets, which encompasses most cryptocurrencies used for investment purposes.
Key implications:
- Applies to tax years beginning after December 31, 2022 (first affecting 2023 tax returns filed in 2024).
- Covers both crypto-to-fiat and crypto-to-crypto transactions involving substantially identical assets.
- Treats digital assets similarly to traditional securities for tax-loss recognition.
This change aligns crypto more closely with established financial markets and signals increasing regulatory scrutiny over digital asset taxation.
Defining “Substantially Identical” in Crypto: Gray Areas Remain
One of the most challenging aspects of applying the wash sale rule to crypto is determining what qualifies as “substantially identical.” The IRS has not yet issued comprehensive guidance specific to cryptocurrencies, leaving room for interpretation.
Consider these common scenarios:
- Bitcoin (BTC) vs. Wrapped Bitcoin (WBTC): Likely considered substantially identical since WBTC is pegged 1:1 to BTC and represents Bitcoin on other blockchains.
- Ethereum (ETH) vs. staked ETH (e.g., stETH): Though technically different tokens, stETH derives its value directly from ETH and may be treated as substantially identical by the IRS.
- Bitcoin (BTC) vs. Litecoin (LTC): Different blockchains, use cases, and market behaviors suggest they are not substantially identical.
- Token swaps during protocol upgrades: If a network forks or migrates (e.g., Ethereum PoW vs. PoS), tax treatment depends on functional and economic similarity.
Until clearer IRS guidance emerges, investors should proceed cautiously when repurchasing similar assets shortly after realizing a loss.

Practical Strategies for Compliance
With stricter rules in place, proactive planning is essential. Here’s how to stay compliant while optimizing your crypto investment strategy:
1. Maintain Detailed Transaction Records
Use reliable crypto tax software or spreadsheets to log:
- Dates of all purchases and sales
- Amounts transacted
- USD values at time of transaction
- Wallet addresses involved
- Associated fees
Accurate records are critical for proving compliance during audits.
2. Avoid Repurchasing Within the 61-Day Window
If you sell crypto at a loss, wait at least 31 days before buying back the same or a similar asset to avoid triggering the wash sale rule.
3. Diversify Instead of Replacing
After selling at a loss, consider investing in a different cryptocurrency or sector (e.g., DeFi, NFTs, Layer 1 platforms) rather than repurchasing the same token.
4. Consult a Tax Professional
Given the complexity and evolving nature of crypto taxation, working with a CPA or tax advisor experienced in digital assets is highly recommended.
Frequently Asked Questions (FAQs)
Does the wash sale rule apply to all cryptocurrencies?
Yes, the rule applies to any digital asset deemed “substantially identical” to one sold at a loss within the 61-day window. The exact scope will depend on future IRS clarifications.
Can I still use tax-loss harvesting with crypto?
Yes, but with limitations. You can harvest losses by selling depreciated assets — just ensure you don’t reacquire substantially identical assets within 30 days before or after the sale.
What happens if I accidentally trigger a wash sale?
The IRS disallows the immediate deduction. The loss increases the cost basis of the new holding, deferring the tax benefit until a future sale outside the wash sale period.
Does moving crypto between wallets count as a repurchase?
No. Transferring crypto between your own wallets or exchanges does not constitute a purchase. The wash sale rule only applies if you actually acquire new units after selling at a loss.
Are decentralized exchanges (DEXs) exempt from wash sale rules?
No. Tax obligations apply regardless of where the trade occurs — centralized exchanges, DEXs, or peer-to-peer transactions all fall under IRS reporting requirements.
Will decentralized finance (DeFi) complicate wash sale tracking?
Potentially. Yield farming, liquidity provision, and token rewards can create complex transaction histories. Use specialized tools to map DeFi activities accurately for tax reporting.

Final Thoughts: Navigating the New Normal
The era of unrestricted tax-loss harvesting in crypto has ended. The inclusion of digital assets under the wash sale rule through the SECURE 2.0 Act reflects broader efforts to integrate cryptocurrency into mainstream financial regulation.
To thrive in this environment:
- Stay informed about regulatory updates.
- Prioritize accurate recordkeeping.
- Leverage technology and expert advice.
- Adapt strategies to comply while maintaining investment goals.
Crypto remains a powerful asset class — but success now requires equal attention to compliance as it does to innovation.
