Crypto Losses Tax Deduction US 2026 – How to Claim Every Dollar

Losing money on crypto hurts. The one silver lining: the IRS lets you use those losses to cut your tax bill. Here's exactly how it works and how to get every dollar you're owed.

Capital Losses Offset Capital Gains First

The IRS applies losses in a specific order — it's not optional:

1. Short-term losses first offset short-term gains
2. Long-term losses first offset long-term gains
3. Excess short-term losses can offset long-term gains (and vice versa)
4. Net capital loss of up to $3,000 per year can offset ordinary income
5. Remaining losses carry forward indefinitely to future years

The $3,000 Annual Limit

After your losses offset all your gains, you can deduct up to $3,000 against ordinary income in a single year ($1,500 if married filing separately). That's $3,000 off your salary income. The rest carries forward — and it never expires. A massive 2022 loss? You might still be using it in 2026.

Realizing Crypto Losses: You Must Actually Sell

Paper losses don't count. You have to actually sell, trade, or dispose of the crypto to realize the loss. This is the entire premise behind tax-loss harvesting — strategically selling losing positions before year-end to lock in the deduction. Here's the best part for crypto: there's no wash sale rule. You can sell and immediately repurchase the same token. Stocks can't do that.

Worthless Crypto and Abandoned Tokens

If a project dies completely and your tokens go to zero:

• Crypto is property, not a security — so the "worthless security" rules don't cleanly apply
• For property, you generally need to actually sell or formally abandon the asset
• Sending tokens to a burn address may constitute abandonment — but document it
• For large worthless positions, get professional advice before claiming

FTX, Celsius, and Exchange Bankruptcy Losses

Customers of FTX, Celsius, and Voyager have been dealing with this since 2022. The general rule: you can claim losses once the bankruptcy determines your recovery amount. The IRS has allowed theft/casualty loss treatment in certain cases. The timing is tricky — most advisors say wait until the final recovery amount is known.

Tax-Loss Harvesting Strategy

1. Review your portfolio in November/December for unrealized losses
2. Sell losing positions to realize losses before December 31
3. Immediately repurchase if you want to maintain exposure (no wash sale rule for crypto)
4. Use losses to offset gains realized earlier in the year
5. Carry forward any excess to reduce next year's tax bill

Reporting Crypto Losses on Form 8949

Every loss transaction gets its own Form 8949 line: date acquired, date sold, proceeds, cost basis, and the loss (shown in parentheses). The totals from 8949 flow to Schedule D, which flows to your 1040.
