What to Know About Crypto Tax Loss Harvesting in 2026

Crypto tax loss harvesting involves selling digital assets that have declined in value to realize a capital loss for tax purposes. That realized loss can offset capital gains. Losses left over after that can reduce a limited amount of ordinary income each year, as explained below.

For the IRS's own guidance, see its digital assets page and Topic 409, Capital gains and losses.

Example
Suppose you have $5,000 in short-term Bitcoin gains and realize a $3,000 short-term Ethereum loss. Your net short-term capital gain drops from $5,000 to $2,000. Assuming the entire reduction would otherwise be taxed at a 24% federal rate, the harvested loss saves $720 in federal income tax.

The $3,000 loss isn't a $3,000 tax refund. Your savings depend on the rate that would have applied to the gains, along with the rest of your tax return.

How does crypto tax loss harvesting work?

Here's how the crypto tax loss harvesting process usually works:

• You find a position that is below your basis.

• You sell it, which turns the paper loss into a real tax loss.

• That loss first offsets capital gains.

• If losses remain, some of the excess may offset ordinary income, up to the annual limit.

• Any remaining net capital loss generally carries forward.

• You report the sale on your tax return, usually through Form 8949 and Schedule D.

What about wash sale rules for crypto?

Under current federal law, the wash sale rule in IRC section 1091 covers stock and securities. It disallows a loss when you buy substantially identical stock or securities within 30 days before or after the sale. Section 1091 has no provision for digital assets, so selling a coin like Bitcoin at a loss and buying it back is not an automatic wash sale. Crypto ETFs and other exchange-traded products are less clear. Their shares trade like stock, and the tax treatment of a quick buyback, or of swapping between a coin and a fund that holds it, is unsettled. Talk to a tax professional before you rebuy within 30 days.

A sale followed by an immediate buyback can still be questioned under the economic substance doctrine in IRC section 7701(o). If the IRS disallows a loss on that basis, a 20% penalty can apply, or 40% if the transaction was not disclosed. The IRS has issued no guidance on crypto buybacks specifically, so consider a tax professional before you sell and rebuy the same day.

The biggest benefit is that realized losses can lower the amount of gains you pay tax on this year. If your losses are big enough, they can also help in future years.

• Lower current-year taxes: Realized losses can offset capital gains from crypto and other capital assets.

• Partial income deduction: Leftover losses can reduce some ordinary income each year, up to the annual limit.

• Future tax value: Unused net capital losses generally carry forward into future tax years.

• Portfolio cleanup: Harvesting losses lets you sell positions you no longer want while improving your tax situation.

Tax loss harvesting can be helpful, but it's not automatic or without risk. You're making a real trade, and your tax results depend on having accurate records. You can sell at a loss and then watch the asset recover.

• Recordkeeping risk: If your basis, fees, or lot selection is wrong, the reported loss may be incorrect.

• Reporting risk: Brokers now file Form 1099-DA. It shows gross proceeds for sales from 2025 on. For sales from 2026 on, it also shows cost basis for crypto bought after 2025 in a custodial account. If your Form 8949 doesn't match, the IRS may ask why.

• Future rule risk: Under current law, the wash sale rule in section 1091 covers stock and securities and has no digital asset provision. Congress could extend it to crypto, so check the rules again before each harvest.

• Lower future cost basis: Repurchasing a coin at a lower price may reduce your current-year taxes while increasing taxable gains on a later sale.

• Trading costs: Exchange fees, slippage, and price fluctuations can reduce or exceed the expected tax benefit.

Most of the effort comes before you actually sell. You need to know what you paid, which lot you're selling, and if the loss will help you this year.

• Review your portfolio and identify positions that are genuinely in the red.

• Check whether you already have gains for the year that those losses could offset.

• Decide which tax lots make sense to sell. Since January 1, 2025, you track basis separately for each wallet and each exchange account. If you don't identify specific units, first in, first out (FIFO) applies to the units in the wallet or account you sold from.

• Sell the asset and lock in the loss.

• Save your records while the details are still easy to find, including the trade timestamp, proceeds, fees, and the units you identified.

• Report the sale on the right forms. Most investors use Form 8949 and Schedule D. Crypto sales go in the digital asset boxes on Form 8949. Use G, H or I for short-term sales and J, K or L for long-term sales. Boxes C and F no longer cover crypto.

This simple example in the table below shows how a loss harvested in the same tax year can offset a gain:

In this example, the harvested loss cancels out the gain. Your total tax bill may not be zero, since your other income is still taxed. You simply have no net capital gain from these trades. If the harvested loss had been $7,000, you would have a $5,000 net capital loss. You could generally deduct $3,000 against ordinary income and carry the other $2,000 forward.

Tax loss harvesting isn't always beneficial. Someone with little or no taxable capital gains may receive less immediate benefit, while someone expecting higher future tax rates should consider the consequences of resetting their cost basis. The decision should account for the investment itself, not just this year's deduction.

Crypto tax loss harvesting timing

People usually think about harvesting losses at two main times:

• Year-end. Sell by December 31 if you want the loss to count for that tax year.

• During market dips. You can also harvest during the year when prices drop, and you already have gains to offset.

Sell when you have a loss you can document and gains it can offset. In practice, this means you have unrealized losses, gains to offset, and enough records to back up the sale.

Good times to consider harvesting losses include year-end planning, sharp market drops, or whenever you're rethinking your position. A tax loss is most useful when it helps solve a real tax issue you already face.

It's worth calculating the expected tax savings before selling. A short-term loss could offset gains taxed at ordinary income rates, while a long-term loss may offset gains already eligible for lower rates. The value depends on your overall gains and losses.

Pro tip
A tax loss doesn't begin when your chart turns red. It starts only when you complete a sale or exchange.

For most individual US taxpayers, the deadline is December 31. The sale or exchange must occur by year-end for the loss to count in that tax year. For stock and securities sold on an exchange, the trade date controls even if the trade settles in January. IRS guidance on this covers securities, not crypto. If your exchange records trades in UTC, the year can end at 4 p.m. Pacific or 7 p.m. Eastern on December 31, so leave a margin and check the timestamp on your trade record.

Yes, but the main limit is the amount of net capital loss you can use against ordinary income in one year. Capital losses offset capital gains first.

• Against capital gains: Capital losses in crypto (and otherwise) generally offset capital gains first.

• Against ordinary income: If losses remain after that, you can generally deduct up to $3,000 per year, or $1,500 if married filing separately.

• Carryforwards: If you still have unused net capital losses after applying the annual limit, you can carry them forward indefinitely. Each carried loss keeps its short-term or long-term character. Any loss still unused at death can only be deducted on the final return.

• Unrealized losses don't count: You need to complete a sale or exchange before the loss matters for your taxes.

There are several legal ways for US taxpayers to reduce their crypto tax bill. Here's a quick look:

• Keep track of crypto cost basis, fees, and transfers so your gains are based on real numbers.

• Harvest losses when you already have gains they can offset.

• Use specific identification if your records are good enough, and the lot choice could change the outcome. For crypto held on an exchange, the rule asks you to tell the broker which units you're selling by the time of the sale, or to set up a standing order. Under IRS relief through December 31, 2026, you can instead record that choice in your own books by the time of sale. For a self custody wallet, record the units you're selling in your own books by the time of the sale.

• Hold long enough to qualify for long-term treatment when that fits your plan.

• Keep your own records even if you receive a 1099-DA, since a 2025 Form 1099-DA reports your gross proceeds, and brokers don't have to report cost basis. Basis reporting starts with crypto you buy on or after January 1, 2026, and keep with the same broker. A blank basis box doesn't mean your basis is zero.

• Get help if things get complicated, especially if you use multiple wallets,

  DeFi, NFTs, or have lots of transactions.

Tax-loss harvesting is simple in theory. Most people run into trouble with bookkeeping. Here's what to look out for when you decide to tax-loss harvest crypto:

• Volatility: A position that looks like an obvious loss today can look very different a few days later.

• Tracking: Different purchase prices, transfer histories, and holding periods can make the math more complicated than it seems.

• Reporting: Broker statements are improving, but many people still need their own records to figure out their cost basis correctly.

Short-term gains are usually taxed at ordinary income rates, while long-term gains are usually taxed at more favorable rates. The IRS nets your results in a set order. Short-term losses first offset short-term gains, and long-term losses first offset long-term gains. Then a net loss on one side offsets a net gain on the other. If you end up with a net capital loss, the annual deduction limit uses short-term losses first, and the rest carries forward. That is why short-term losses can be especially useful when you already have short-term gains on the books.

For example, suppose you have $4,000 in short-term gains, $1,000 in short-term losses, and $2,000 in long-term losses. You end up with a $3,000 net short-term gain and a $2,000 net long-term loss. After netting, you have a $1,000 net short-term gain, which is taxed at ordinary income rates.

Higher earners may also owe the 3.8% net investment income tax on capital gains. It applies when modified adjusted gross income is above $200,000 for single filers, $250,000 for married couples filing jointly, or $125,000 for married filing separately. Harvested losses that offset your capital gains can also lower this tax.

State income tax may also apply to crypto gains, and states do not all follow the federal rules for capital losses. Check your state's rules or ask a tax professional.

Still, the best approach depends on your overall mix of gains and losses. Good tax planning looks at the whole picture, not just one trade.

Tax-loss harvesting with NFTs

Tax-loss harvesting can apply to NFTs held as capital assets and sold at a loss. The basic capital gain and capital loss rules still apply, with one caveat. Under IRS Notice 2023-27, an NFT is treated as a collectible if the asset or right it represents is a collectible, such as a gem or possibly a work of art. Long-term gains on collectibles can be taxed at up to 28%. The challenge is liquidity. An NFT strategy doesn't help much if there's no real market or practical way to sell.

Pro tip
Some NFTs may be taxed as collectibles, which can raise the top rate on long-term gains to 28%. We explain this in our expert guide to NFT tax loss harvesting.

What if I have both gains and losses in the same cryptocurrency?

You might still be able to harvest a loss if you own different tax lots of the same coin with different cost bases. The outcome depends on which units you sold and whether your records back up those sales.

If you cannot adequately identify the units sold, FIFO generally applies. It counts only the units in the wallet or account you sold from, not all your holdings. That can change your gain or loss.

A big price drop is not a deductible loss on its own. In a 2023 memo, the IRS said a token that still trades on at least one exchange is not worthless, and simply holding it is not abandonment. Crypto is not a security under the worthless securities rule, so a loss on worthless or abandoned crypto is a miscellaneous itemized deduction, and individuals can't claim those. If the token still trades, selling it, even for very little, gives you a capital loss you report on Form 8949.

Theft follows different rules. If your crypto was stolen in a deal you entered into to make a profit, such as a fake investment platform, you may be able to claim a theft loss on Form 4684 for the year you discover it. The deduction is limited to your basis. It is an itemized deduction, and the ban on miscellaneous deductions doesn't apply to it. In a 2025 memo, the IRS allowed the loss for victims of a fake investment scheme, a compromised account scam, and a phishing scam. It denied it for romance and fake kidnapping scams because those victims had no profit motive. A personal theft loss counts only when it is tied to a federally or state-declared disaster.

If your crypto is stuck in an exchange bankruptcy, such as FTX or Celsius, you generally can't deduct anything while your claim has a reasonable prospect of recovery. The loss becomes fixed when the claim is settled, decided, or abandoned. The IRS has not issued guidance on crypto lost to lost keys or a forgotten password, so ask a tax professional about that case.
