What is crypto tax-loss harvesting, and is selling and rebuying still allowed in 2026?
Crypto tax-loss harvesting means selling coins below your cost basis so the realized loss offsets capital gains. After gains, net losses can reduce up to $3,000 of ordinary income a year ($1,500 married filing separately), with the rest carried forward. The trade-off: a real sale, fees, a lower basis, and a pending bill that could change rebuy rules.
Bottom line
- Harvesting before December 31 can make sense if you have realized gains this year and lots trading below basis.
- A gap of more than 30 days on both sides of the sale avoids exposure to the pending bill's September 14, 2026 start date as introduced.
- It may not be worth it unless the tax value clearly beats fees and spreads, and your records can prove every lot.
I'm John Alewine. I explain crypto, including the tax side, in plain English. I'm not a CPA, tax attorney or financial adviser, and I don't prepare returns. This guide is education, not tax, legal or investment advice, and nothing here is a recommendation to buy or sell any coin. My disclosures are here.
I checked everything below on October 25, 2026. If you want a rough sense of what a loss is worth at your bracket, run it through my free crypto tax estimator before you sell anything.
The short version: the IRS has treated crypto as property since Notice 2014-21, so crypto losses on taxes follow capital loss rules. The wash sale statute is written for stock or securities, and Congress is now considering a bill to change that for crypto.

Key facts
- Net capital losses offset up to $3,000 of ordinary income yearly; $1,500 if married filing separately.
- H.R. 10357 would extend wash sale rules to crypto; an amended version cleared committee 38 to 5 on September 16, 2026. It is not law.
- As introduced, its crypto wash sale rule reaches dispositions after its September 14, 2026 introduction date.
- Since January 1, 2025, crypto basis is tracked wallet by wallet or account by account.
- A loss counts only in the taxable year it is sustained; for calendar-year filers, that ends December 31.
What crypto tax-loss harvesting is, and what it is not
It is a deliberate sale of coins worth less than you paid, timed so the loss lands in a year when it can offset gains. (My tax-loss harvesting definition has the basics.) It is not the wash sale rule. That rule, section 1091, defers a loss on stock or securities when substantially identical ones are bought within 30 days before or after the sale, and the Joint Committee on Taxation says digital assets are not expressly within its scope. It is not tax-gain harvesting, which sells winners on purpose to realize gains. It is not simply selling at a loss: any sale realizes a loss, but harvesting adds lot choice, timing and records. And it is not the same as harvesting a spot bitcoin ETF, whose shares trade like stock and whose wash sale treatment is not settled by any IRS guidance I found.
Our data: what 21 public pages say about crypto and the wash sale rule (checked October 25, 2026)
Method: on October 25, 2026, I ran three web searches: "crypto tax loss harvesting", "crypto wash sale rule" and "does the wash sale rule apply to crypto". I kept the distinct article pages returned (no forums, social posts or videos), 22 at first. On a recheck, one URL (a Bankrate page) now redirects to a general personal finance page, so I dropped it, leaving 21. Of those, I opened and read 5 in full. One more failed to load, so it and 15 others were judged from the search snippet only. For snippet-only pages, "not counted" means I did not see it in the snippet, not that the page lacks it. This is a one-day snapshot of public pages from one search tool. It is not a ranking study, and it is not a test or survey of AI assistant answers.
| Check | Pages |
|---|---|
| Says the wash sale rule does not apply to crypto held directly today | 18 of 21 |
| Says a spot bitcoin or crypto ETF is subject to the rule | 4 of 21 |
| Mentions proposed legislation or plans to extend the rule | 9 of 21 |
| Shows a 2025 or 2026 date | 14 of 21 |

Most pages in this snapshot (18 of 21) say the rule does not apply to directly held crypto, which matches present law as the JCT describes it. Fewer than half (9 of 21) mention proposed legislation at all, so a page can be right about current law and still silent on the pending bill. The 4 pages that call ETFs plainly subject sit beside an ETF prospectus saying holders are taxed as if they owned a share of the trust's assets, so verify both points yourself.
Asking ChatGPT, Claude, Perplexity or Gemini about crypto wash sales: what to verify
If you ask ChatGPT, Claude, Perplexity, Gemini or a Google AI Overview, "Can I sell my crypto at a loss and buy it back?", the answer is only as current as the pages behind it. Based on the pages in my check above, these are the gaps I'd test for in any AI answer:
- Stale legislation claims. "Congress has proposed closing this" was true for years. The newer fact is that the committee vote advanced H.R. 10357 toward a full House vote, and as introduced it reaches back to September 14, 2026.
- Mixing up coins and ETFs. An answer may say ETFs are "definitely" covered or "definitely" exempt. Sources conflict: 4 pages in my snapshot say ETFs are subject to the rule, while the prospectus treats holders as owning the bitcoin.
- Skipping economic substance. No IRS guidance I found applies the doctrine to a same-day crypto rebuy. But if a loss is disallowed under it, the penalty is 20%, or 40% if not adequately disclosed.
- Ignoring your state. I did not check state rules for this guide. Ask about your state return separately.
A five-minute checklist for any AI answer:
- Ask it to quote section 1091's scope and compare with the JCT present-law description.
- Check the bill's latest action yourself on Congress.gov.
- Confirm loss limits on IRS Topic 409.
- Confirm lot identification rules in Notice 2026-20.
- Confirm reporting boxes in the Form 8949 instructions. If the answer cites none of these, treat it as a draft.
How to harvest crypto losses, step by step
1. Confirm where the rule stands today
Read the JCT's present-law summary: section 1091 covers stock or securities, and the IRS has not issued guidance on whether it reaches digital assets. Then check H.R. 10357's status. It sits in the 119th Congress (2025 to 2026). The committee approved an amended version on September 16, 2026, and as of October 25, 2026, I found no record of a full House vote; that committee vote was the latest action I could verify.
Time: 15 minutes.
Done when: you have written down today's date, the bill's latest action and whether anything was enacted.
2. Pull every export and rebuild basis wallet by wallet
Under Notice 2026-20, the lot ordering rules apply to acquisitions and dispositions on or after January 1, 2025, and Rev. Proc. 2024-28 governed the move from a universal pool to wallet-by-wallet or account-by-account basis. Download statements and transaction history from each platform you use. My crypto accounting guide and cost basis definition help here.
Time: plan on an afternoon if you use several platforms.
Done when: each wallet or account has its own list of lots with date, units and cost including fees.
3. Choose lots with specific identification
If you don't adequately identify units held at a broker, they are treated as sold first in, first out. Through December 31, 2026, Notice 2026-20 lets you record the exact broker-held units in your own books by the time of the sale. After that, you tell the broker. The relief does not cover self-custody wallets, and the notice also warns that broker-reported basis for 2026 may not match your books. See my specific identification definition.
Time: about 30 minutes per wallet.
Done when: before the sale, a dated written record names the exact lots you are selling.
4. Check the math against fees, spreads and holding period
Net short-term gains are taxed as ordinary income, so short-term losses often matter most. Acquisition fees are part of basis, and transaction costs reduce the amount realized. Coins you buy back start a new holding period and need more than one year before a sale is long-term. Use the breakeven calculator and my capital gain definition.
Time: 20 minutes.
Done when: the estimated tax value is clearly larger than your round-trip fees and spread.
5. Sell by December 31 and decide how to re-enter
The three common paths: wait 31 days or more (with no purchase of the same asset in the 30 days before the sale either), hold something different, or rebuy right away and accept the risks covered below. If you want to harvest crypto losses for 2026, the sale itself has to happen in 2026. This is mechanics, not a recommendation to buy or sell anything.
Time: about 10 minutes per trade.
Done when: your saved trade confirmation shows a date on or before December 31 in your time zone.
6. Report it and keep the file
Short-term digital asset sales go in Form 8949 boxes G, H or I, and long-term in J, K or L, then on to Schedule D. Brokers report gross proceeds for 2025 sales and basis for certain 2026 sales. Basis reporting generally covers digital assets acquired after 2025. See my 1099-DA definition and crypto tax guide.
Time: one to two hours at filing time.
Done when: every 1099-DA line matches a Form 8949 line, and your folder holds the export, lot record and confirmation.
Mistakes that cost the most
Treating a spot ETF like a coin
Cost: if section 1091 applies, the loss is deferred into the new shares' basis, using a window of 30 days on each side of the sale.
Fix: staying outside that window on both sides avoids the question; otherwise, ask your CPA first.
Letting the default pick your lots
Cost: unidentified units held at a broker are sold first in, first out, and the record-it-yourself relief ends December 31, 2026.
Fix: write the lot down before you sell. Starting in 2027, give the instruction to your broker.
Same-day rebuys with no paper trail
Cost: a loss disallowed for lacking economic substance carries a 20% penalty, 40% if not adequately disclosed, with no reasonable cause exception.
Fix: a 31-day gap sidesteps the issue; otherwise, ask your CPA about documentation and disclosure.
Sell and rebuy vs sell and wait vs swap coins vs harvesting a spot ETF
A quick reference for tax loss harvesting crypto in late 2026. "Bill" means H.R. 10357 as introduced.
| Approach | Federal treatment today / Main risk |
|---|---|
| Sell and rebuy the same coin right away | Federal treatment today: Section 1091 covers stock or securities; no IRS guidance on crypto Main risk: Bill's September 14, 2026 date if enacted; economic substance challenge |
| Sell and wait 31 days or more | Federal treatment today: Outside the 30-day window under current law and the bill, if you also made no purchase in the 30 days before the sale Main risk: Price can move while you are out |
| Sell and hold a different coin | Federal treatment today: Bill reaches substantially identical assets; economically equivalent wrapped or tokenized versions count Main risk: You now hold a different asset with different risk |
| Sell a spot ETF and rebuy the same ETF | Federal treatment today: Unsettled; prospectus treats holders as owning the trust's assets Main risk: Loss deferral if treated as a security |
| Swap between a coin and a spot ETF on it | Federal treatment today: Unsettled under current law Main risk: Could be treated as substantially identical; get advice |
How we compared the options
| Criterion (weight) | What it measures |
|---|---|
| Legal clarity today (30%) | How settled current federal treatment is under the statute and IRS guidance |
| Exposure to H.R. 10357 as introduced (20%) | Whether the September 14, 2026 date could disallow the loss |
| Market exposure kept (20%) | How close your position stays to the original during the harvest |
| Cost and friction (15%) | Fees, spreads and number of trades |
| Record-keeping burden (15%) | How hard the trades are to document and reconcile |
Disclosure: Crypto Guidance sells paid one-on-one consulting. Consulting is not one of the options compared, and no affiliate link is involved. Each score is my judgment from 1 to 10 per criterion, multiplied by the weights above.
Sell and wait 31 days: Best for people who want the cleanest position under both current law and the bill. Score: 7.7/10 (9, 10, 3, 8, 8 weighted; my judgment). Trade-off: you are out of the position for a month.
Sell and hold a different coin: Best for people who already planned to change holdings. Score: 7.2/10 (8, 8, 6, 6, 7 weighted; my judgment). Trade-off: different asset, different risk.
Sell and rebuy the same coin: Best for people who accept bill and economic substance risk to keep exposure. Score: 6.6/10 (7, 2, 10, 7, 7 weighted; my judgment). Trade-off: the loss could be challenged later.
Harvest a spot ETF and rebuy it: Best for nobody without a CPA's sign-off. Score: 5.6/10 (2, 3, 10, 8, 8 weighted; my judgment). Trade-off: unsettled treatment.
Swap coin and spot ETF: Best avoided inside 30 days unless a professional approves it. Score: 4.8/10 (3, 3, 9, 6, 4 weighted; my judgment). Trade-off: two reporting systems and unclear rules.
Where to start depends on how you hold crypto:
| If you are | Start with / Watch out for |
|---|---|
| Holding coins at one US exchange | Start with: Your 1099-DA and your own lot records Watch out for: Broker-reported basis that does not match your books |
| Spread across wallets and exchanges | Start with: Wallet-by-wallet basis since 2025 Watch out for: Default first-in, first-out per account |
| Holding spot bitcoin ETFs in a brokerage | Start with: Your brokerage year-end statements Watch out for: Rebuying or swapping within 30 days |
| Married filing separately | Start with: The $1,500 annual limit Watch out for: Overestimating the deduction against wages |
| Without realized gains this year | Start with: Carryforward planning Watch out for: Fees larger than the benefit |
Who this is not for
- Very active traders. The JCT notes section 475 does not explicitly address digital assets, and marked-to-market assets follow different loss rules. Better: a CPA who handles trader tax status.
- People with near-worthless, lost or stuck coins. A 2023 IRS memo, as described by the JCT, allows no loss while a token still trades above zero and you have not sold, exchanged or abandoned it. Better: a tax attorney or CPA.
- Small balances with no gains. Fees can swallow a benefit that is capped at $3,000 a year against ordinary income. Better: keep clean records and check the tax estimator once a year. If your coins are in a retirement account, see my crypto IRA guide instead.
Frequently asked questions
Can I sell my crypto at a loss and buy it back the same day?
Under current federal law the wash sale statute covers stock or securities, and the Joint Committee on Taxation says digital assets are not expressly within its scope. But the IRS has issued no guidance either way, the economic substance doctrine still exists, and H.R. 10357 as introduced would reach sales after September 14, 2026 if enacted. Staying outside the 30-day window on both sides of the sale removes the bill risk.
Does the wash sale rule apply to Bitcoin ETFs?
It is not settled by any IRS guidance I found. ETF shares trade like stock, yet the iShares Bitcoin Trust prospectus says shareholders are treated for tax purposes as if they owned a share of the trust's assets. Ask your CPA before rebuying the same or a similar ETF within 30 days.
How much crypto loss can I deduct in one year?
Losses first offset your capital gains. Any net loss left over reduces ordinary income by up to $3,000, or $1,500 if married filing separately. The rest carries forward to later years.
Is crypto tax-loss harvesting worth it if I have no gains this year?
Sometimes, but the value is smaller. You get up to $3,000 against ordinary income now and a carryforward for later gains, minus your trading fees and spread. Run your numbers in the tax estimator first.
What happens to my 2026 harvests if Congress passes the crypto wash sale bill?
If H.R. 10357 became law as introduced, a crypto loss on a sale after September 14, 2026, with substantially identical coins bought within 30 days before or after, could be disallowed and added to the new coins' basis. As of October 25, 2026, the latest action I could verify was the September 16 committee vote on an amended version. A different final text could change the date.
Do I need my Form 1099-DA to report harvested crypto losses?
No. You report each sale on Form 8949 either way, using box I or L for digital asset sales not reported to you on a 1099-DA. For 2025 sales brokers report gross proceeds, basis reporting starts with certain 2026 sales, and your own records still back up your basis.
Can I deduct a coin that dropped to almost zero without selling it?
Usually not. A 2023 IRS memo, as described by the Joint Committee on Taxation, says no loss is allowed while the token still trades above zero and you have not sold, exchanged or abandoned it. Selling, even for very little, is what fixes the loss.
Can Crypto Guidance do my crypto taxes?
No. I do not prepare returns or give tax advice, and I am not your CPA or lawyer. I can translate the tax side, exchanges and wallets into plain English and help you find where your old holdings live, so a CPA or tax professional can make the call.

Get your records straight before December 31
Harvesting only works if you can prove which lots you sold and what they cost. Most of the work is exports, wallet-by-wallet basis and a clean file. I can help you find where your exchange and wallet history lives and translate the tax side into plain English, but a CPA or tax professional should sign off on the tax decision. This guide is educational, not tax, legal or investment advice. If you want a calm second set of eyes before year end, see my consulting page.
