NFT Tax-Loss Harvesting Deadline 2026: What to Do Before December 31

Farmer HarveyOctober 20, 2026

If you want a loss on your 2026 taxes, the sale has to happen in 2026. For US taxpayers that means your NFT or token has to be sold, onchain and confirmed, by December 31, 2026. Nothing you do on January 1 helps this year's return.

That's the whole deadline. The rest of this guide is about not missing it.

The short version

Hard deadline: December 31, 2026. The sale must be confirmed onchain, not just signed.
Practical deadline: December 30. Block timestamps are in UTC, and the IRS hasn't said which time zone counts. Don't find out the hard way.
Abstract holders: Harvest stops supporting Abstract on December 15. Harvest anything there before then.
Holding something worthless isn't enough. You need a sale. Price going to zero doesn't create a deductible loss on its own.
Losses offset gains first, then up to $3,000 of ordinary income ($1,500 if married filing separately). Anything left carries forward to future years.
Wash sales: still don't apply to crypto under current law. A bill that would change that for fungible tokens cleared committee in September. It wouldn't cover NFTs. More on that below.

Not tax advice. Run your plan past a CPA. We list a few crypto-native ones on our Tax Help page.

Why "sold" is the only thing that counts

The IRS treats crypto, NFTs included, as property. You realize a gain or loss when you dispose of it: sell it, swap it, spend it. A drop in price, however brutal, is an unrealized loss. It doesn't go on your return.

People hope there's a shortcut. There mostly isn't. The IRS said in 2023 (CCA 202302011) that a token that crashed but still had some value didn't produce a deductible loss just because it crashed. Claiming it as abandoned or worthless instead runs into a second wall. For individual investors, those losses are miscellaneous itemized deductions. The 2017 tax law suspended them, and the 2025 tax law made that permanent.

A sale sidesteps all of it. You sell the asset, the difference between what you paid and what you got is a capital loss, and capital losses go on Form 8949 like any other.

The problem with dead NFTs and tokens is that nobody's buying. That's the gap Harvest fills: we buy them for 1 gwei each, so you have a real sale to report.

The year-end calendar

Now through November: inventory

List every wallet you've used this year, including the ones you forgot about.
Find the losers: NFTs and tokens worth a fraction of what you paid.
Work out the cost basis of each one: purchase price plus gas and fees, in dollars, at the time you bought. Our cost basis guide walks through it.
Since 2025 the IRS wants basis tracked wallet by wallet, not pooled across all your wallets. Keep each wallet's records separate.
Add up your realized gains for the year so you know how much loss you can use.

December 1–15: harvest

Abstract: Harvest's Abstract support ends December 15. Don't leave it to the last day.
Everything else: this is the sweet spot. Gas is usually calmer than the last week of the year, and you have time to fix anything that goes wrong.
Batch it. Harvest charges one flat fee per transaction, for up to 500 items, so one big batch costs the same as one item.
On Ethereum and Base, leave "Check offers first" on. If someone is still bidding on something, you take the bid and still realize a loss.

December 16–30: stragglers

Sweep the wallets you missed.
Expect busier blocks and higher gas as everyone else remembers the deadline at once.
Aim to be done by December 30.

December 31: hard stop

If you're harvesting on December 31, do it early in the day and wait for the confirmation.
A transaction stuck in the mempool at midnight isn't a 2026 sale.

January to April 15, 2027: file

Download your receipts and save the transaction hashes.
Import your wallets into your tax software, or hand everything to your CPA.
Losses go on Form 8949 and Schedule D. Most 2026 returns are due April 15, 2027.

How much the loss is worth

Losses first offset gains of the same type. Short-term losses offset short-term gains, long-term offset long-term, and then whatever is left crosses over. Short term means you held the asset for a year or less.

If your losses are bigger than your gains, up to $3,000 of the excess offsets ordinary income each year. The rest carries forward, with no expiry.

A hypothetical:

You realized $8,000 of short-term gains trading tokens this year.
You harvest 40 NFTs you paid $14,000 for in total. Sold for 1 gwei each, that's a $14,000 short-term loss.
The loss wipes out the $8,000 gain and leaves $6,000.
$3,000 of that offsets your salary this year. The other $3,000 carries forward to 2027.

At a 32% federal bracket, that's about $3,520 off this year's federal tax ($11,000 × 32%), with more to come next year. Your numbers will be different. The shape won't.

Fees and gas matter here too. Your sale costs reduce your proceeds, which makes the loss slightly bigger. Keep the records.

Wash sales: what changed in 2026

The wash sale rule stops you from selling at a loss and buying the same thing back within 30 days. Under current law it covers "stock or securities." Crypto is property, so most practitioners read the rule as not applying to it. The IRS has never issued guidance saying otherwise.

That may change. On September 16, 2026, the House Ways and Means Committee approved H.R. 10357, the Digital Asset Tax Certainty Act, by 38 to 5. Among other things it extends the wash sale rule to "traded digital assets."

Two details matter for harvesting:

It isn't law. It still needs a full House vote, the Senate, and a signature.
It's written to reach back. As drafted, it would apply to sales made after the bill was introduced in mid-September 2026, not just after it passes.

And one detail matters most:

The bill defines "traded digital asset" as fungible, with quotes readily available on an exchange. NFTs aren't fungible. A dead token nobody quotes anywhere wouldn't qualify either.

So what does that mean in practice?

Harvesting NFTs: the bill as written wouldn't touch them.
Harvesting dead tokens with no market: very likely the same.
Selling a liquid token at a loss and buying it back: this is where the risk is. If the bill passes in its current form, buying back within 30 days of the sale could disallow the loss, even for a sale made this fall. If you want to keep that exposure, consider rotating into something similar but not the same, or waiting out the 30 days. Ask your CPA.

When you harvest an NFT with us, it goes into the barn, where anyone can start a public auction. You could bid on your own NFT later, but so can everyone else. That's an arm's-length sale, which is the point.

Will I get a 1099-DA?

Maybe, but not from Harvest.

Starting with 2025 sales, centralized exchanges and other custodial brokers send Form 1099-DA, reporting what you sold and for how much. For assets bought on the same platform from 2026 onward, they also report your cost basis.

Selling from your own wallet to a smart contract is different. Congress repealed the rule that would have made DeFi protocols report, so Harvest doesn't issue 1099-DAs. You report the sale yourself, using your receipts and transaction hashes. Your tax software or CPA does this all the time.

If you also traded on an exchange this year, make sure the 1099-DA it sends matches your own records. Its basis can be blank or wrong for anything you transferred in from another wallet.

Not in the US?

The calendar is different elsewhere, and so are the rules on buying back:

UK: the tax year ends April 5, not December 31. HMRC applies a 30-day matching rule to cryptoassets, so buying back the same asset within 30 days changes which purchase your sale is matched against.
Canada: the tax year is the calendar year. The superficial loss rule can deny a loss if you or someone affiliated with you buys the same property back within 30 days, before or after the sale.
Australia: the tax year ends June 30. The ATO has warned that selling and buying back mainly to create a loss can be struck down as a wash sale.

Check your local rules. They change.

Common mistakes

Waiting for December 31. Gas spikes, wallets glitch, transactions stall. Leave yourself room.
Forgetting wallets. That burner from the 2021 mint counts.
No cost basis. A loss you can't prove is a loss you can't use. Find the original purchase transaction now, while block explorers and marketplaces still have it.
Assuming "worthless" means deductible. Without a sale, it generally isn't.
Harvesting things with real bids. Check for offers first. A real bid beats a deduction.
Not keeping receipts. Save the transaction hash for every harvest.

FAQ

What's the last day to harvest crypto losses for 2026?

December 31, 2026, for US taxpayers. The transaction has to be confirmed onchain by then. Aim for December 30 to be safe.

Does the date I sign the transaction count, or the date it confirms?

Plan on the confirmation date: the timestamp of the block your transaction lands in. That timestamp is in UTC, so a late-night December 31 sale in the US can land on January 1 by the block's clock.

Can I harvest an NFT and buy it back?

Under current US law, the wash sale rule doesn't apply to NFTs, and the bill moving through Congress wouldn't change that, since it only covers fungible tokens. On Harvest, harvested NFTs go to the barn, where anyone can start a public auction for them, so you can't count on getting the same one back anyway.
