How to Report Crypto Losses on Your Taxes

You sold some crypto at a loss — maybe you panic-sold during a crash, or a token went to zero, or you got out of a bad position. It stings. But here’s the silver lining most investors miss: in the US tax system, investment losses are valuable. They can offset your gains, reduce your taxable income, and even carry forward to future years. The catch? Crypto losses follow specific rules, and claiming them wrong — or missing them entirely — costs you real money.

This guide covers how crypto losses work on US taxes: what’s deductible, how to calculate it, the strategies smart investors use (tax-loss harvesting), and the traps to avoid.

The basics: how crypto losses work

The IRS treats crypto as property, so losses follow capital loss rules — the same framework as stocks:

• Realized losses only. A loss counts only when you actually sell, trade, or dispose of the asset. Watching your portfolio drop 70% creates no tax benefit until you sell. Unrealized (“paper”) losses don’t count.
• Losses offset gains first. Your capital losses offset your capital gains dollar-for-dollar — crypto losses can offset stock gains and vice versa.
• Then up to $3,000 against ordinary income. If losses exceed gains, you can deduct up to $3,000 per year ($1,500 if married filing separately) against wages and other ordinary income.
• The rest carries forward. Unused losses carry forward indefinitely to future tax years. A big loss in 2026 can shelter gains for years.
• Short-term vs. long-term netting. Short-term losses first offset short-term gains, long-term losses offset long-term gains, then they cross-net. The ordering affects your final tax bill.

What counts as a “disposition” (triggering the loss)

• Selling crypto for dollars at a loss — the straightforward case.
• Trading crypto for crypto at a loss — each trade is a taxable event; if you swapped at a lower value than your cost basis, that’s a realized loss.
• Spending crypto at a loss — buying something with depreciated crypto realizes the loss.
• Worthless tokens: if a token went to zero, you generally need to actually dispose of it to claim the loss — even selling for $0 or sending to a burn address. Abandonment rules are murky; a documented disposal is cleaner.
• Stolen or hacked crypto: generally not deductible as a capital loss for individuals under current law — theft losses face severe restrictions since the 2017 tax law changes. This is a painful gap; check current IRS guidance or a CPA for your situation.

The IRS’s digital asset guidance is the authoritative reference, and it’s worth reading before filing.

Tax-loss harvesting: turning losses into strategy

Tax-loss harvesting means deliberately selling losing positions before year-end to realize losses that offset your gains. It’s standard practice in stock investing, and it works for crypto too — with one notable crypto-specific advantage:

The wash-sale loophole (for now)

Stocks are subject to the wash-sale rule: if you sell at a loss and rebuy within 30 days, the loss is disallowed. Crypto is currently not subject to the wash-sale rule (it’s property, not a security, under this rule), which means you can sell crypto at a loss and immediately rebuy it — harvesting the tax loss while maintaining your position. Congress has repeatedly proposed closing this loophole, so verify it’s still open for the tax year you’re filing — but as of now, it’s one of crypto’s genuine tax advantages.

How to harvest properly

1. Review positions before year-end — November/December, not April.
2. Identify lots trading below cost basis — your tracking software shows this (see our guide to tracking your crypto for tax season).
3. Sell to realize the loss, optionally rebuying immediately given the wash-sale situation.
4. Document everything — dates, amounts, USD values, and which tax lots you sold.
5. Don’t harvest blindly — transaction fees, spreads, and the risk of being out of the market during a rebound are real costs. Harvesting makes sense when the tax savings clearly exceed the friction.

Calculating your losses correctly

Your loss = proceeds minus cost basis (what you paid, plus fees). Sounds simple; in practice it requires:

• Complete transaction history across every exchange and wallet — missing buys inflate your gains and erase your losses.
• A consistent accounting method (FIFO, LIFO, HIFO, specific identification) applied across all your crypto. The method choice significantly affects which losses you realize.
• Proper handling of transfers between your own wallets — these aren’t sales, but sloppy records make software misclassify them.

This is where most people go wrong: they report the losses they remember and miss the ones buried in old wallets or closed exchanges. A proper crypto tax tool that imports everything is nearly essential once you’ve traded actively. For record-keeping systems, accounting software for individuals can help organize the broader picture, and our guide to self-employed taxes covers finding professional help.

Traps to avoid

• Assuming exchange 1099s are complete. Exchange tax forms often don’t include your full cost basis — especially for crypto you transferred in from elsewhere. The 1099 is a starting point, not the answer.
• Forgetting DeFi and NFT losses. Failed DeFi positions, worthless NFTs, and rugged tokens all generate harvestable losses — but only if tracked and properly disposed of.
• Claiming losses on crypto you still hold. Paper losses aren’t deductible, no matter how red the portfolio is.
• Mixing personal and business treatment. If your crypto activity qualifies as a business (mining, professional trading), different rules apply — get professional advice.
• Waiting until April. Harvesting must happen in the tax year. Discovering losses in March is too late to act on them.

The SEC’s investor education resources won’t help with taxes specifically, but they’re useful for the broader discipline of treating crypto as a serious investment activity.

The bottom line

Reporting crypto losses on your taxes means: realize losses through actual dispositions, offset them against gains first then up to $3,000 of ordinary income, carry the rest forward, consider year-end tax-loss harvesting (mindful of the wash-sale situation), and keep complete records across every platform you’ve touched. Losses hurt — but harvested properly, they’re one of the few consolation prizes the tax code offers investors. Don’t leave that money on the table.

Frequently Asked Questions

Can I deduct crypto losses on my taxes?

Yes — realized capital losses on crypto offset capital gains dollar-for-dollar, then up to $3,000 per year against ordinary income, with the remainder carrying forward indefinitely.

Do I need to sell to claim a crypto loss?

Yes. Only realized losses count — you must sell, trade, or otherwise dispose of the asset. Paper losses on crypto you still hold aren’t deductible.

Does the wash-sale rule apply to crypto?

Currently no — crypto isn’t subject to the wash-sale rule, so you can sell at a loss and immediately rebuy. Congress has proposed changing this, so verify for the current tax year.

What if my crypto was stolen or the exchange collapsed?

Stolen crypto generally isn’t deductible as a capital loss for individuals under current law — a painful gap. Exchange bankruptcy claims may eventually produce recoveries with their own tax treatment. Consult a CPA for your specific situation.

How far back can I carry crypto losses?

Capital losses carry forward indefinitely until used up — there’s no expiration. (Carrybacks generally aren’t available for individual capital losses.)
