Filing and credit
CRS delivering Hong Kong account data to the Mainland is not the completion of an individual income-tax filing. The filing and credit rules for Mainland tax residents’ overseas income rest on Public Notice 2020 No. 3 and the rules in force — the institution reports; the individual files; one does not discharge the other.
Two processes, two clocks
The institution’s CRS filing discharges its AEOI duty: Hong Kong institutions report to the IRD after the reporting period, and the IRD transmits to the partner authority. A Mainland tax resident’s overseas income is filed in the individual income tax annual reconciliation from 1 March to 30 June of the following year. The parties, deadlines and consequences are independent, and usually more than a year apart.
What must be filed
Under Public Notice 2020 No. 3, overseas interest, dividends, gains on property transfers, business income and service income of a Mainland tax resident are all within scope, reconciled under the corresponding income categories. Where filings have long been missing and account data have been exchanged, the data sit directly in the authority’s matching view — concealment moves from hard-to-find to directly comparable.
Credit
Foreign tax paid may be credited under either the comprehensive method or the per-country method, chosen once and not switched. The claim requires a tax payment certificate issued by the overseas authority — no certificate, no credit. The ceiling follows the China tax computed on the same income, with carry-forward of excess under the rules then in force.
The taxpayer cannot be swapped
Profits tax paid by the Hong Kong company is a company-level charge and is not a credit against the shareholder’s personal dividend tax. Company earns, company pays tax, company distributes, individual receives, individual files and claims — five steps, two taxpayers, never conflated.
Dual residence
Where the same person is resident under both sides’ rules, Article 4 of the Arrangement applies the tie-breaker (permanent home → centre of vital interests → habitual abode). At the CRS level, however, both identities may be reported by institutions — residence determination and data exchange are separate layers.
Risk and the sensible route
Whether a given case is examined, and how much is assessed, depends on amounts, years and the timing of voluntary correction — it is case-specific. The sound route is self-verification first, then consider voluntary correction; take advice from a Mainland tax adviser for the execution. This page explains the mechanism and is not a case opinion.
Mainland individual income tax rules follow Public Notice 2020 No. 3 and the IIT Law as currently in force.
