Binance, Coinbase & Kraken Tax Report UK 2026 – How to Use It

Binance, Coinbase, and Kraken provide automated tax reports. But how do you use them for UK Self Assessment? Here's the practical guide.

Download Your Tax Report

Binance: Account → Download Center → Tax Reports (CSV format available)

Coinbase: Settings → Crypto Tax Reports → Download (provides CSV with all transactions)

Kraken: Settings → API → Generate API keys for tax export (integrates with tax software)

What the Report Contains

• All buy/sell transactions
• Staking rewards and other income
• Fees paid
• Transfer history
• Timestamps and prices

How to Use It for HMRC

1. Calculate your gains/losses: For each sale, compute gain/loss (sale price – cost basis)
2. Match cost basis: Use FIFO or average cost (whatever you declared)
3. Total capital gains: Sum all gains minus all losses
4. Subtract allowance: Subtract £3,000 (or carried losses)
5. Calculate tax: Remaining × 20% (or 10% if basic rate)
6. Report on Self Assessment: Enter into "Capital gains" section

Important Limitations of Exchange Reports

Exchange reports are rough approximations. They don't account for:

• Crypto-to-crypto swaps: Exchanges often miss these or misreport
• Transfers between exchanges: Can be confusing (not a taxable event, but can mess up matching)
• Your exact tax position: The report doesn't know if you're basic or higher rate
• Staking income classification: May lump it incorrectly

HMRC Will Get the Same Data (via CARF)

From 2026, HMRC will receive the same data from these exchanges via CARF.

If your Self Assessment doesn't match, HMRC will notice and contact you.

Therefore: Use the exchange report as a starting point, but verify it's accurate.

Best Practice for Self Assessment

• Download the exchange report
• Import into tax software (Koinly, CryptoTax, or Excel)
• Review for errors or missing transactions
• Calculate your final position
• File Self Assessment with these figures
• Keep the exchange report as backup evidence

Strategies for 2026

Action: Download your 2025/26 reports now and review them carefully. If there are errors, contact the exchange. Document everything.
