Cross-border tax transparency and digital assets
CARF and the amended CRS: reporting readiness for cross-border families holding digital assets
G70 content review draft | Information as at 5 August 2026
The new reporting framework is not limited to exchange accounts. Identity, control, tax residence, fiat flows and on-chain transfers will need to reconcile within one evidence base.
Hong Kong remains at the legislative stage
The relevant bill was gazetted in May 2026 and introduced for first reading in June. The Inland Revenue Department expressly states that it remains subject to Legislative Council scrutiny. If enacted, CARF-related amendments are intended to apply from 1 January 2027, the amended CRS from 1 January 2028, and Hong Kong aims to begin its first automatic CARF exchanges in 2028. These are planned dates, not statutory deadlines already in force.
CARF and CRS observe different data relationships
CRS is organised primarily around financial accounts and investment entities. CARF starts with reporting crypto-asset service providers effecting relevant transactions for clients, collecting tax-residence information on users and controlling persons and reporting transactions under the rules. The amended CRS is also intended to cover certain digital financial products and entities investing in relevant crypto-assets. Coordination between the regimes does not mean every data point need be prepared only once.
No bank account does not mean no reportable activity
CARF uses functional definitions. Relevant activities may include exchanges between crypto-assets and fiat currency, exchanges between relevant crypto-assets, and transfers to users or external wallet addresses. Self-custody does not automatically make transactions previously conducted through a service provider untraceable. Families need to connect on-chain addresses, exchange records, bank flows and beneficial owners.
Data governance is often harder than the form
A family may hold assets through individuals, companies, trusts, foundations or investment entities while using multiple exchanges, brokers, custodians and self-hosted wallets. Place of formation, place of management, tax residence, controlling persons and links to service providers can all affect classification. Relocation, a new status, a change in management location or a change of trust control may also make a long-standing self-certification inaccurate.
Preparation begins with a reconcilable asset map
Reliable records should capture original cost, time, asset type, on-chain transaction identifier, wallet address, fiat inflows and outflows and the purpose of inter-entity transfers, and reconcile to bank and provider statements. Building that record now does not predetermine the reporting conclusion. It allows tax and legal advisers to reclassify from consistent evidence once final rules are settled, rather than reconstructing years of activity before a deadline.
