Does the IRS know about my crypto?

Increasingly, yes. Starting in 2025/2026, crypto exchanges must report transactions on Form 1099-DA (Digital Assets). The IRS also receives 1099-B, 1099-K, and 1099-MISC from exchanges. They've issued John Doe summonses to major exchanges (Coinbase, Kraken) for user records. The IRS crypto question on the top of Form 1040 ('Did you receive, sell, or otherwise dispose of any digital assets?') signals this is a priority.

What crypto transactions are taxable?

Selling crypto for cash (capital gain/loss), trading one crypto for another (taxable — each swap is a sale), using crypto to buy goods/services (taxable at fair market value), receiving crypto as income/payment (ordinary income), mining and staking rewards (ordinary income when received), and airdrops (ordinary income at fair market value). Simply buying crypto with USD and holding it is NOT a taxable event.

What if I lost money on crypto — should I still report it?

Absolutely. Capital losses can offset capital gains dollar-for-dollar, and up to $3,000 of net losses can offset ordinary income each year. Remaining losses carry forward indefinitely. Not reporting losses means you're paying MORE taxes than you should. Many people who lost money in crypto market downturns can use those losses to reduce their tax bill.

I Forgot to Report Crypto on My Taxes — What Now?

If you forgot to report crypto on your taxes, fix it now. The IRS has made crypto enforcement a top priority, exchanges are sending transaction data to the IRS, and every Form 1040 now asks a direct yes/no question about digital assets.

$10,000 long-term gain (15% rate)	$1,500	$1,500 + ~$75 interest	$1,500 + $300 penalty + interest

Don’t Forget Losses

If You Lost Money	Tax Benefit
Losses offset gains dollar-for-dollar	Reduces capital gains tax to $0 if losses exceed gains
Up to $3,000 offsets ordinary income	Reduces your regular income tax
Remaining losses carry forward	Use in future years indefinitely
Example: $15,000 in losses, $5,000 in gains	$5,000 offsets gains + $3,000 offsets income + $7,000 carries forward

The Bottom Line

The IRS is aggressively pursuing unreported crypto. Exchanges are now reporting to the IRS, and blockchain analysis tools make on-chain activity traceable. Amend your return before the IRS contacts you — self-correcting avoids the 20% penalty and demonstrates good faith. And if you lost money, reporting those losses can actually lower your tax bill.
