As of mid‑2026, the IRS wash sale rule under Internal Revenue Code § 1091 does not generally apply to cryptocurrency. The IRS continues to treat digital assets such as Bitcoin, Ethereum, and most other tokens as property rather than securities for federal tax purposes[reference:0][reference:1]. Because § 1091 specifically applies to "stock or securities," crypto falls outside its scope[reference:2].
This means that, for now, you can sell a cryptocurrency at a loss and repurchase the same asset within minutes—even on the same day—and still claim the capital loss on your tax return[reference:3][reference:4]. Stock investors do not have this flexibility; if they sell a stock at a loss and buy it back within 30 days, the loss is disallowed.
However, the landscape is shifting. Multiple legislative proposals introduced in 2025 and 2026 aim to close what lawmakers call the "fake-loss loophole" by extending wash sale rules to digital assets[reference:6][reference:7]. Taxpayers should monitor developments closely.
The wash sale rule prevents investors from claiming a tax deduction for a loss on the sale of stock or securities if they acquire substantially identical stock or securities within 30 days before or after the sale[reference:8]. The 30‑day window on each side creates a 61‑day period that includes the sale date[reference:9].
When a wash sale occurs, the loss is disallowed for the current tax year. However, the disallowed loss is not permanently lost—it is added to the cost basis of the replacement shares, which reduces future gain or increases future loss when those shares are eventually sold[reference:10].
The IRS's position, rooted in IRS Notice 2014-21, classifies cryptocurrency as property[reference:11]. The wash sale rule's statutory language applies only to "stock or securities." Since crypto is not a security under the tax code, the rule does not reach it[reference:12].
This creates a significant tax planning opportunity: you can harvest losses from crypto positions without being forced to wait 30 days to reestablish your position[reference:13]. But as discussed below, that opportunity may be time‑limited.
| Aspect | Stocks & Securities | Cryptocurrency (2026) |
|---|---|---|
| Wash sale rule applies? | Yes — IRC § 1091 | No — classified as property |
| 30‑day waiting period | Required to claim loss | Not required |
| Loss disallowed on repurchase | Yes, if within 61‑day window | No, loss remains claimable |
| Basis adjustment | Disallowed loss added to new basis | No adjustment needed |
| Tax‑loss harvesting flexibility | Limited | High |
Understanding what triggers a taxable event is the first step to compliance. Under IRS rules, you have a taxable event whenever you dispose of cryptocurrency[reference:14]. Common taxable events include:
Non‑taxable events include:
Good recordkeeping is the backbone of accurate tax reporting. For each cryptocurrency transaction, you should maintain:
Many exchanges now provide transaction history exports and, starting in 2026, Form 1099‑DA reports[reference:23]. However, exchange records are not always complete or accurate. You should reconcile them with your own records.
Report capital gains and losses from cryptocurrency on Form 8949 (Sales and Other Dispositions of Capital Assets) and Schedule D (Form 1040)[reference:24][reference:25]. Form 8949 requires you to list each disposition individually, including:
Short‑term holdings (one year or less) are taxed at ordinary income rates; long‑term holdings (more than one year) qualify for preferential capital gains rates[reference:26].
Beginning with the 2025 tax year, custodial brokers must report digital asset transactions to the IRS using Form 1099‑DA[reference:27][reference:28]. For 2025 transactions, brokers report gross proceeds; starting in 2026, they must also report cost basis for covered assets[reference:29].
Importantly, Form 1099‑DA includes Box 1i — "Wash Sales Loss Disallowed." Even though the wash sale rule does not currently apply to most crypto, the IRS has built the reporting infrastructure to track it[reference:30]. This signals that the agency is preparing for a potential change.
The current exemption of crypto from wash sale rules is not guaranteed to last. Several legislative efforts are underway to change the law.
Introduced in May 2026, the Digital Asset Protection, Accountability, Regulation, Innovation, Taxation, and Yields (PARITY) Act proposes a comprehensive tax framework for digital assets[reference:32]. Among its provisions, it would extend the wash sale rules under IRC § 1091 to digital assets, closing the "fake-loss loophole"[reference:33][reference:34]. The bill also addresses staking rewards, stablecoins, and charitable contributions[reference:35].
Introduced on June 8, 2026, H.R. 9172 (Applying Existing Tax Anti‑Abuse Rules to Digital Assets Act) would similarly amend § 1091 to apply wash sale rules to "specified assets," which include digital assets other than qualified U.S. dollar stablecoins[reference:36][reference:37]. It also addresses constructive sale rules and provides exceptions for assets acquired in connection with transaction validation[reference:38].
As of mid‑2026, no legislation extending the wash sale rule to crypto has been enacted[reference:39]. But the direction of travel is clear. If you are aggressively harvesting crypto losses today, you should plan for the possibility that these rules will eventually apply[reference:40].
Use this checklist to stay on top of your crypto tax obligations in 2026:
Scenario: Alex bought 1 Bitcoin (BTC) in January 2025 for $60,000. By December 2026, the price has dropped to $40,000. Alex sells the BTC at a $20,000 loss and, on the same day, buys 1 BTC back at $40,000.
Under current rules: Alex can claim the full $20,000 capital loss on their 2026 tax return. The loss can offset other capital gains and, if there are excess losses, up to $3,000 of ordinary income (with carryover to future years).
If the wash sale rule applied: The loss would be disallowed because Alex repurchased the same asset within 30 days. The $20,000 loss would be added to the cost basis of the new BTC, making the new basis $60,000. Alex would not benefit from the loss until selling the new BTC in a future tax year.
Takeaway: The current crypto exemption provides meaningful tax flexibility. But if legislation passes, this strategy will no longer work.
Every sale, trade, or spend is a taxable event, regardless of size. The IRS requires you to report all dispositions[reference:42].
Exchange records can be incomplete or incorrect. Always reconcile with your own transaction log[reference:43].
Without accurate basis, you cannot calculate gain or loss correctly. This leads to overpaying or underpaying tax.
Legislative momentum is strong. Planning for potential changes now can save you from surprises later[reference:44].

Always verify current rules with the IRS website, official Treasury guidance, or a qualified tax professional before making decisions.
As of mid‑2026, the IRS wash sale rule (IRC § 1091) does not generally apply to cryptocurrency. The IRS continues to treat digital assets as property, not securities, so the 30‑day restriction does not currently block loss deductions on crypto sales[reference:45]. However, legislation has been proposed that would extend the rule to digital assets[reference:46].
The wash sale window is 61 days total: 30 days before the sale, the day of the sale, and 30 days after[reference:47]. If you acquire substantially identical stock or securities within that period, any loss from the sale is disallowed for current tax purposes[reference:48].
The IRS has not issued definitive guidance on what "substantially identical" means for digital assets[reference:49]. For stocks, it generally covers the same security or one that is nearly identical. For crypto, questions remain about whether different tokens, wrapped assets, or ETFs would count. Proposed legislation like H.R. 9172 would treat tokenized and wrapped assets as substantially identical to their underlying assets[reference:50].
Report capital gains and losses from crypto on Form 8949 and Schedule D (Form 1040)[reference:51]. You must list each disposition, including date acquired, date sold, proceeds, cost basis, and gain or loss. You also must answer the digital asset question on Form 1040[reference:52].
Form 1099‑DA is a new information return that custodial brokers use to report digital asset transactions to the IRS[reference:53]. It includes Box 1i — "Wash Sales Loss Disallowed." Even if the wash sale rule doesn't currently apply to most crypto, the IRS has built the reporting infrastructure to track it[reference:54].
Yes, under current rules you can sell crypto at a loss and repurchase the same asset immediately while still claiming the loss[reference:55]. This makes crypto more flexible than stocks for tax‑loss harvesting[reference:56]. But this could change if legislation is enacted[reference:57].
Several bills have been proposed, including the PARITY Act (H.R. 8899)[reference:58] and H.R. 9172 (Applying Existing Tax Anti‑Abuse Rules to Digital Assets Act)[reference:59]. Both would extend IRC § 1091 wash sale rules to digital assets[reference:60][reference:61]. As of mid‑2026, neither has been enacted into law[reference:62].
You should consult a qualified tax professional if you have significant crypto trading activity, are unsure about your cost basis, need to navigate complex transactions like staking or DeFi, or want to plan for potential legislative changes.
