Trade History Alone Is Not Enough
Do not wait until filing season. Save trade exports, deposits, withdrawals, fees, cost basis evidence, TxIDs, wallet addresses, and screenshots, then back them up monthly.
Records to Preserve Now
- Taiwan's Ministry of Finance has explained that non-recurring domestic personal virtual asset gains may be treated as property transaction income, calculated from proceeds minus cost and fees.
- For domestic businesses, sales or exchanges of virtual assets should be calculated by subtracting related costs and expenses from revenue.
- The FTX case shows that records are useful not only for tax, but also for disputes, insolvency, and loss documentation.
How to Organize Crypto Records
- Export spot, convert, earn, deposit, and withdrawal history monthly.
- For wallet transfers, save TxID, network, address, amount, time, and transaction purpose.
- Use a spreadsheet with date, platform, asset, cost, proceeds, fees, and notes.
- Store exchange emails, KYC notices, freeze notices, and support ticket screenshots together.
Common Mistakes
- Saving screenshots only without CSV or PDF exports.
- Not recording fiat value at the time of crypto-to-crypto swaps.
- Withdrawing to self-custody without labeling the purpose.

Q: What if an overseas exchange export is incomplete?
A: Export whatever is available, then supplement it with bank records, TxIDs, emails, screenshots, and notes.
