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

Lost money on crypto? The IRS lets you use those losses to reduce your tax bill. Here is the complete guide to claiming crypto capital losses.

Capital Losses Offset Capital Gains First

Crypto losses first offset crypto and other capital gains dollar-for-dollar:

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

If your total capital losses exceed your gains, you can deduct up to $3,000 against ordinary income ($1,500 if married filing separately). Any remaining loss carries forward to the next tax year – it never expires.

Realizing Crypto Losses: You Must Sell

Unrealized losses (paper losses) are not deductible. You must actually sell, trade, or dispose of the crypto to realize and claim the loss. This is the basis of tax-loss harvesting – strategically selling losing positions before year-end.

Worthless Crypto and Abandoned Tokens

If a cryptocurrency project fails and the token becomes completely worthless (market cap goes to zero, project abandoned):

• You may be able to claim a worthless security loss – but crypto is property, not a security
• For property: you generally need to actually sell or abandon the asset
• Sending tokens to a burn address may constitute abandonment
• Consult a tax professional for large worthless token positions

FTX, Celsius, and Exchange Bankruptcy Losses

Customers of bankrupt exchanges (FTX, Celsius, Voyager) may claim losses once the bankruptcy process determines their recovery amount. The IRS has provided some guidance allowing theft/casualty loss treatment in certain cases. The timing and amount depend on what the bankruptcy distributes.

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

Each loss transaction requires a line on Form 8949 with: date acquired, date sold, proceeds, cost basis, and the negative gain (loss). Losses are shown in parentheses. The totals flow to Schedule D.
