How to Report Cryptocurrency Transactions — Even When You Don’t Know All the Details
Cryptocurrency taxation is becoming one of the most misunderstood areas for taxpayers — and the IRS is now aggressively enforcing reporting requirements. A recent U.S. Tax Court case (Paschall v. Commissioner, T.C. Memo 2026‑46) reaffirmed that crypto staking rewards are taxable the moment you gain control of them, even if you didn’t sell the tokens.
Here’s a clear guide to help taxpayers stay compliant.
1. What the IRS Requires You to Report - The IRS treats cryptocurrency as property, not currency. This means you must report:
- Sales of crypto
- Trades between tokens
- Crypto used to buy goods/services
- Staking rewards
- Mining rewards
- Airdrops
- Interest from lending platforms
- Rewards from DeFi platforms
Even if you didn’t receive a Form 1099, the IRS still expects reporting.
2. What If You Don’t Know Your Cost Basis? -Many taxpayers lose access to:
- Old exchange accounts
- Wallet history
- Transaction logs
- Cost basis from early purchases
- Records from delisted coins or closed platforms
If you don’t know your basis, the IRS allows you to: Reconstruct records using:
- Blockchain explorers
- Exchange CSV downloads
- Bank statements
- Wallet history
- Third‑party tools (CoinTracker, Koinly, Accointing)
Use reasonable estimates when records are missing-The IRS expects good‑faith reconstruction, not perfection. Document your methodology
If audited, documentation protects you.
3. Key Lesson from the 2026 Tax Court Case
The Court held that:
- “Staking rewards are taxable when the taxpayer gains dominion and control over the tokens.”
This means:
- You don’t need to sell the tokens
- You don’t need to withdraw them
- You don’t need to convert them to cash
If the tokens hit your wallet and you can sell them — they are taxable
5. How to Protect Yourself
- Keep detailed records
- Use crypto tax software
- Save all exchange statements
- Track staking rewards monthly
- Work with a CPA who understands digital assets
Crypto tax mistakes can lead to:
- IRS notices
- CP2000 underreporting letters
- Penalties
- Interest
- Audits
Crypto taxation is complex — but compliance is possible with the right guidance. If you’re unsure how to report your transactions or reconstruct missing data, professional help can save you from costly IRS issues.
