Document the classification question
Hong Kong’s profits-tax analysis distinguishes business profits from gains on capital assets and considers the source of profits. IRD’s digital-assets discussion covers investment holdings, cryptocurrency businesses, business payments and employment receipts. Do not classify all token receipts identically because the same wallet received them.
Create a short explanation of why each account exists and how it is used. Record whether an asset was acquired for longer-term investment, inventory, payment or another purpose. Keep supporting agreements and decisions made at the time, rather than reconstructing a convenient explanation only after prices have changed.
Build a transaction and evidence ledger
For each movement, keep the date, time zone, asset, quantity, fees and counterparty or wallet address. Attach bank statements and exchange exports. Add a Hong Kong-dollar valuation and its source where relevant to the analysis, while retaining the original currency amounts so later corrections remain traceable.
Label transfers between your own wallets separately from trades and receipts. Explain bridging, wrapped assets and rewards in an exception log. These labels organise the review; they do not determine the legal treatment. Reconcile each asset’s opening balance, inflows, outflows and closing balance before calculating any proposed result.
Prepare the territorial facts
Where a business is involved, document what activities produced the profit and where they were carried out. Keep the people, contracts and operational arrangements visible in the file. The location of an exchange server or bank account alone should not replace a properly supported assessment of the business facts.
Give your adviser a reconciled ledger, the activity explanation and the unresolved-event list. Ask which records, valuation approach and reporting treatment apply to your circumstances. The objective is an auditable position with evidence, rather than a spreadsheet that assumes every transaction is outside tax because it involved cryptocurrency.
