Record Keeping for Crypto Taxes
Overview
Proper record keeping is the foundation of crypto tax compliance. You need detailed records of every acquisition, disposal, transfer, income event, and DeFi interaction. Exchanges may close, lose data, or delist tokens — maintaining your own records is essential. Tax authorities can audit several years back, and the burden of proof is on you.
Key Points
For every transaction, record: date, time, type (buy/sell/trade/receive), amount, asset, FMV in local currency, counterparty/exchange, transaction ID/hash, fees paid. Export exchange history monthly (don't wait — exchanges can lose data). Track wallet-to-wallet transfers (not taxable but needed for audit trail). Maintain records for 5-7 years minimum (varies by jurisdiction).
Tax Rates
No direct impact — but poor records lead to higher taxes because you may not be able to prove your cost basis, resulting in a zero cost basis (100% gain).
Reporting Requirements
Download CSV/Excel exports from all exchanges regularly. Use portfolio tracking apps (CoinGecko, Delta, Blockfolio) to mirror transactions. Back up records to multiple locations. Consider a dedicated crypto tax software that auto-imports.
Tips & Recommendations
Start record keeping NOW, not at tax time. The single biggest tax problem crypto investors face is not having adequate records when it's time to file. Set a monthly reminder to export your exchange history and verify your portfolio tracker is up to date.
