Many traders treat record exports as an end-of-year tax chore. That is risky. If you change exchanges, close an account, migrate from one tax tool to another or split activity across wallets, missing transfers and cost-basis gaps can make realized PnL look wrong.
Coinbase says users can download tax documents, gain-loss summaries and raw transaction history through Coinbase Taxes. Kraken describes a Statement & Tax Center with exports and account documents, and its account-history guide points users to exports for trades, ledgers and statements. Binance.US says users can export custom transaction history or create a tax API key for third-party tools.
A practical workflow is simple. First, export the full account history, not just recent trades. Second, separately save fills, deposits, withdrawals, conversions, staking or reward income, and fee records. Third, preserve wallet addresses and transaction hashes so transfers between your own wallets are not mistaken for taxable sales by software.
Before switching tools, import a small sample period and reconcile it against the exchange balance and realized trade history. If the tool cannot explain a large gain, loss or missing cost basis, stop and fix the data before relying on the report. This is especially important for traders using multiple exchanges, DeFi wallets or futures accounts.
