How to Report Crypto Losses on Your Taxes

Crypto Losses Are Valuable — Don't Ignore Them

If you sold crypto for less than you paid, you have a capital loss — and that loss has real tax value. Many crypto holders skip reporting losses because they think "there's nothing to report if I lost money." That's a mistake. Losses offset gains, reduce your tax bill, and can even reduce your ordinary income.

How Capital Losses Work

Under IRC §1211, capital losses can be used in two ways:

1. Offset capital gains: Capital losses reduce your capital gains dollar-for-dollar. $10,000 in losses against $10,000 in gains = $0 net capital gain, $0 tax.
2. Offset ordinary income (up to $3,000/year): If your losses exceed your gains, the excess can be deducted against ordinary income (salary, business income) up to $3,000 per year for individuals. Remaining losses carry forward.

Losses don't expire during your lifetime. A $100,000 loss year in a crypto bear market creates carryforwards that can shelter future gains for many years.

Short-Term vs. Long-Term Loss Netting Rules

The IRS requires you to net losses against gains of the same type first (IRC §1222):

1. Short-term losses offset short-term gains first
2. Long-term losses offset long-term gains first
3. Excess short-term losses then offset long-term gains (or vice versa)
4. Any remaining net loss applies against ordinary income (up to $3,000)

Strategically, short-term losses are most valuable against short-term gains (taxed up to 37%). A $10,000 short-term loss offsetting a short-term gain saves up to $3,700 at the top rate — versus $2,000 if applied against a long-term gain.

The Wash Sale Rule Does NOT Apply to Crypto (Yet)

In the stock market, the wash sale rule (IRC §1091) disallows a loss if you buy the same security within 30 days before or after the sale. This rule does not apply to cryptocurrency as of 2026 — crypto is property, not a security. You can sell at a loss and immediately repurchase the identical asset without losing the deduction. Take advantage of this while it lasts.

How to Report Crypto Losses on Form 8949 and Schedule D

Every loss (and gain) from crypto must be reported individually on Form 8949, which then aggregates onto Schedule D.

For each transaction on Form 8949, you report:

• Description of property (e.g., "0.5 BTC")
• Date acquired
• Date sold
• Proceeds (what you received)
• Cost basis (what you paid)
• Gain or loss (proceeds minus basis — negative = loss)

Schedule D then nets all your short-term transactions (Part I) and long-term transactions (Part II), applies the $3,000 ordinary income offset if applicable, and calculates the carryforward.

Loss Carryforward: How It Works

If you have $50,000 of net capital loss in 2025:

• You deduct $3,000 against 2025 ordinary income
• $47,000 carries forward to 2026
• In 2026, if you have $20,000 in capital gains, the carryforward eliminates them completely
• Remaining $27,000 carries to 2027, and so on

Report prior-year capital loss carryforwards on Schedule D, Line 6 (short-term) or Line 14 (long-term). Your prior year Schedule D shows the carryforward amount.

Exchange Collapses: Can You Deduct Stuck Funds?

If your funds are locked on a bankrupt exchange (Celsius, FTX, Voyager), the loss may not be deductible until the bankruptcy proceedings determine what recovery you'll receive. Once recovery is determined (or you receive final notice of complete loss), the loss becomes deductible as a capital loss or potentially a theft/casualty loss — see our FTX Bankruptcy Tax Guide and Celsius Bankruptcy Tax Guide for specifics.
