Cryptocurrency Tax Guide 2026: Capital Gains, Losses, and Reporting
9 min read · Updated June 2026
The IRS treats cryptocurrency as property, which means every sale, trade, or spend is a taxable event. This guide covers everything you need to know about reporting crypto gains and losses on your 2026 tax return.
How the IRS Taxes Cryptocurrency
Since 2014, the IRS has classified virtual currency as property for tax purposes. This means:
- Buying crypto with USD — not taxable
- Selling crypto for USD — capital gain or loss
- Trading one crypto for another — taxable (you must calculate gain/loss in USD)
- Using crypto to buy goods/services — taxable
- Earning crypto (mining, staking, airdrops) — ordinary income at fair market value
Short-Term vs Long-Term Capital Gains
The tax rate you pay depends on how long you held the crypto before selling:
Short-Term Capital Gains (held 1 year or less)
Taxed at your ordinary income tax rate (10%–37% for 2026). These are the same rates as your salary or freelance income.
Long-Term Capital Gains (held more than 1 year)
Taxed at preferential rates based on your taxable income:
| Filing Status | 0% Rate | 15% Rate | 20% Rate |
|---|---|---|---|
| Single | Up to $47,150 | $47,151–$518,900 | Over $518,900 |
| Married Filing Jointly | Up to $94,300 | $94,301–$583,750 | Over $583,750 |
The NIIT: An Extra 3.8% Tax
If your modified adjusted gross income (MAGI) exceeds $200,000 (single) or $250,000 (married filing jointly), you owe an additional 3.8% Net Investment Income Tax (NIIT) on your investment income, including crypto gains.
Calculating Your Gain or Loss
For each crypto transaction, calculate:
Your cost basis is what you paid for the crypto (including fees). If you bought Bitcoin at $40,000 and sold at $65,000, your gain is $25,000 per coin.

Tax-Loss Harvesting
If you have losing positions, you can sell them to offset your gains. This is called tax-loss harvesting and it can significantly reduce your tax bill:
- Capital losses offset capital gains dollar for dollar
- If losses exceed gains, you can deduct up to $3,000 per year against ordinary income
- Unused losses carry forward to future years
- Watch out for wash sales: The IRS has proposed treating crypto like securities for wash sale rules — repurchasing the same crypto within 30 days may disallow the loss deduction
Reporting Crypto on Your Tax Return
You'll need these forms:
- Form 8949 — List each crypto sale/trade with date acquired, date sold, proceeds, cost basis, and gain/loss
- Schedule D — Summary of all capital gains and losses
- Schedule C — If you mine crypto as a business
- Schedule 1 — For airdrops, staking rewards, and other miscellaneous income
Common Mistakes to Avoid
- Not reporting crypto-to-crypto trades — Every swap is taxable, even if you never cashed out to USD
- Forgetting about airdrops and staking — These are taxable as ordinary income when received
- Using wrong cost basis method — FIFO is the default, but specific identification can save taxes
- Ignoring state taxes — Most states also tax capital gains at ordinary income rates
- Not keeping records — Exchanges may only show recent transactions; keep your own records
The Bottom Line
- Every crypto sale, trade, or spend is a taxable event
- Hold for more than 1 year for lower long-term capital gains rates
- Watch for the 3.8% NIIT if your income is above $200K/$250K
- Tax-loss harvesting can offset gains, but be careful with wash sale rules
- Keep detailed records of every transaction, including dates and USD values
