A Hong Kong ID holder who has spent four months in the city opens a bank CRS self-certification and stalls on the line asking for a jurisdiction of tax residence. A director of a Hong Kong company living in Dubai receives a demand from a Mainland counterparty for proof of resident status before a dividend is paid. The question is formally the same for both, and in Hong Kong it works differently from systems where residence sets the extent of the tax charge.
Hong Kong taxes source. Salaries tax, profits tax and property tax attach to where the income arose, and the IRD says so in terms: "There is therefore no distinction made between residents and non-residents. A resident may therefore derive profits from abroad without suffering tax; conversely, a non-resident may suffer tax on profits arising in Hong Kong" (ird.gov.hk). Foreign profits stay outside the charge even once the money is remitted to Hong Kong.
The practical consequence: resident status changes almost nothing about the Hong Kong tax bill. It matters where relief has to come from another jurisdiction — under one of the 51 comprehensive double taxation agreements (CDTAs) in force — or where a financial institution has to fix a reporting jurisdiction for its client.
Concept
"Residence" covers three separate tests in the Hong Kong context, each addressed to a different party and each with different consequences. They overlap only in part.
| Question | Rule | What is tested | Consequence |
|---|---|---|---|
| Is the income taxable in Hong Kong | IRO ss 8, 14 | Source of the income; residence is not tested at all | Salaries tax on Hong Kong days, profits tax on Hong Kong-source profits |
| Am I a resident for treaty purposes | Article 4 of the relevant CDTA plus the IRD criteria | Ordinarily resides, more than 180 days in a year of assessment or more than 300 days over two consecutive years; for companies, incorporation or management and control | Entitlement to a Certificate of Resident Status and to claim relief from the treaty partner |
| What goes in the bank's CRS form | The AEOI rules administered by the IRD | The same test as for the certificate | Reporting jurisdiction and the TIN equivalent — the HKID number |
Separating the three matters in any live file: a person can pay salaries tax with no entitlement to a certificate, and can equally hold CDTA resident status having paid no Hong Kong tax at all.
Who Passes the IRD Test
The list of persons the IRD admits to the certificate is short and closed (ird.gov.hk). An individual qualifies who ordinarily resides in Hong Kong, or who stays in Hong Kong for more than 180 days during a year of assessment, or for more than 300 days in two consecutive years of assessment one of which is the relevant year. A company, partnership, trust or other body of persons qualifies if incorporated or constituted in Hong Kong, or, if incorporated or constituted outside Hong Kong, where it is managed or controlled in Hong Kong.
A fifth category arrived in 2025 — the re-domiciled company. The Companies (Amendment) (No. 2) Ordinance 2025, gazetted on 23 May 2025, introduced the mechanism for moving a company onto the Hong Kong register and at the same time amended section 2 of the IRO: references to a company "incorporated in Hong Kong" now include a re-domiciled company. When the resident definition in a CDTA is construed, such a company counts as a Hong Kong company. The certificate application follows completion of the re-domiciliation procedure, including deregistration in the former place of incorporation, with the certificate of re-domiciliation attached.
"Ordinarily resides" is not reduced to a day count and is assessed by the IRD on the circumstances: a permanent home, family, the character of the presence. The IRD sets the day thresholds with "or", so they operate as free-standing alternatives to ordinarily resides: 190 days in a year of assessment earn the certificate without any separate weighing of the centre of vital interests. That does not carry over to the treaty outcome — where residence is dual, the Article 4(2) tie-breakers decide, and the centre of vital interests is one of them. The general arithmetic of day counting is set out in Tax Residency: 183 Days.
Certificate of Resident Status: The Procedure
The certificate is the only document by which Hong Kong confirms status to a treaty partner. The procedure runs as follows.
- Prerequisite. A comprehensive agreement must be in effect with the jurisdiction. 51 are in force (the most recent, with Türkiye, entered into force on 30 January 2026 and applies from the year of assessment 2027/2028); eight more are signed and awaiting entry into force: Barbados, Cyprus, Jordan, Kyrgyzstan, Maldives, Nigeria, Norway and Rwanda. The composition of the network and the rates under the treaties that matter are set out in Hong Kong's tax treaty network.
- Form. For the agreement with the Chinese Mainland — IR1313A for entities and IR1314A for individuals; for other jurisdictions — IR1313B and IR1314B. The current edition of all four forms is dated July 2025.
- Filing. Online through the Individual Tax Portal, the Business Tax Portal or the Tax Representative Portal under eTAX, or by post to the IRD Tax Treaty Section. There is no fee. One application covers at most three calendar years of claim.
- Outcome. The IRD's target is 21 working days to issue the certificate or to notify a request for further information or a decision that the application cannot be accepted. Under the Mainland agreement a digital certificate has been issued since 10 November 2025: the PDF lands in the portal message inbox and the partner verifies authenticity through the e-Proof service. The download access code is valid for 90 days.
- Refusal and escalation. Where a partner denies relief the applicant believes is due, the competent authority of Hong Kong will consider engaging the partner under the Mutual Agreement Procedure of the relevant agreement.
What the Certificate Does Not Do
The IRD issues the certificate solely in support of a treaty claim. Asked directly whether it will issue one where the applicant does "not need to claim tax benefits under DTAs, but would like to apply for a CoR for other purposes", the Department answers "No". A request framed around a bank, an immigration authority or a foreign counterparty outside a treaty claim will not be granted.
The second limit bites harder. The IRD warns that issue of a certificate does not guarantee the claim will succeed — the decision on relief belongs to the treaty partner, which also tests the remaining conditions.
Mainland dividends are the standard case. Article 10(2) of the Arrangement caps withholding at 5% where the beneficial owner is a company directly owning at least 25% of the capital of the paying company, and at 10% otherwise. The Mainland authority applies its own beneficial owner test under STA Circular 2018 No. 9, and the IRD requires Part 2 of the Appendix to form IR1313A to be completed under the guidelines in Note 3 whenever the claim falls within Articles 3 or 4 of that Circular.
Companies: Management and Control Against Source of Profits
For a company the Hong Kong question splits in two. Residence for the certificate turns on incorporation or on the test of being normally managed or controlled in Hong Kong. Liability turns on the source of the profits and is indifferent to residence in every respect: a Hong Kong company operating abroad lawfully pays nil, while a foreign company with a Hong Kong source pays profits tax at the two-tiered rate of 8.25% on the first HK$2 million of assessable profits and 16.5% above that.
The qualification of recent years is the FSIE regime. From 1 January 2023 foreign dividends, interest, IP income and equity interest disposal gains, and from 1 January 2024 disposal gains on property of every type, are deemed Hong Kong-sourced when received in Hong Kong unless the recipient meets one of the exceptions. The principal exception is the economic substance requirement: a pure equity-holding entity needs adequate human resources and premises, everything else needs qualified employees and operating expenditure in Hong Kong.
The regime reaches only members of MNE groups within s 15H(1) of the IRO, so a standalone Hong Kong company outside an international group falls outside it. Large groups additionally test themselves against the 15% global minimum. The corporate mechanics are covered in Hong Kong Company, and the collision of two jurisdictions over one legal person in Hong Kong company, Singapore resident.
Salaries Tax and Remote Work
For an individual the connecting factor is source: Hong Kong employment is distinguished from non-Hong Kong employment, the latter taxed on Hong Kong days only through the apportionment in s 8(1A), with short visits taken out of charge by a separate 60-day rule. The Goepfert tests, the day computation, dual contracts and the interaction with the 183-day treaty exemption are treated separately, in Hong Kong salaries tax for remote workers.
Two facts belong here. First, Hong Kong's 60-day rule and Singapore's 60-day rule are built differently and are not interchangeable. Second, the salaries tax standard rate has been two-tiered since the year of assessment 2024/25 — 15% on the first HK$5 million of net income and 16% on the remainder — with the tax charged as the lower of the progressive computation and the standard rate.
Bank Self-Certifications, CRS and the HKID Number
The bank asks an HKID holder about the reporting jurisdiction; entitlement to treaty relief is of no interest to that form. For AEOI purposes the IRD applies the same test as for the certificate: ordinarily resides, more than 180 days in a year of assessment, or more than 300 days over two consecutive years. Hong Kong can be declared on the form only by meeting one of those criteria; holding the card and a visa does not by itself count. The exchange mechanics and the consequences of a defective self-certification are covered in CRS, and the immigration routes and their relation to tax in Hong Kong Residency.
The TIN equivalent for an individual is the HKID number, including the letter or numeral in the bracket and without the bracket itself. The IRD warns separately that the "TIN" printed on the Tax Return-Individuals and the Notice of Assessment is no TIN equivalent and serves only for eTAX login. For an entity the TIN equivalent is the first eight numerals of the Business Registration number.
Risks
The Singapore counterpart is issued by IRAS, and comparing the two procedures pays off when a group chooses between the jurisdictions: Certificate of Residence in Singapore. The wider map of Hong Kong topics sits in the Hong Kong hub.
