CRS self-certification: checking the relevant official guidance
Hong Kong's Inland Revenue Department (IRD) states the self-certification rule in one place: its AEOI page on Residency for Tax Purposes and Taxpayer Identification Number (TIN). Account holders or controlling persons may be requested to declare their tax residence and provide their TIN in self-certifications, so that financial institutions can verify tax residence. Where more than one jurisdiction is involved, all jurisdictions of residence and the corresponding TIN, if applicable, should be reported in the same self-certification. The wording below reflects the version of that page captured on 14 October 2026.
What the guidance asks you to declare
The requirement has two parts and one purpose. You declare the jurisdiction or jurisdictions where you are resident for tax purposes. You provide the TIN issued for each one. The purpose, in the IRD's own words, is to enable the financial institution to verify your tax residence.
That framing matters for anyone treating the form as a conclusion. The self-certification is an input to the institution's verification. It is not itself a determination of where you are taxable.
Who receives the request
The cited IRD sentence names account holders and controlling persons as possible subjects of a self-certification request. This article does not use that sentence to define every type of controlling person or decide how a particular entity account is treated.
If you have more than one tax residence
Where a person is tax-resident in more than one jurisdiction, the IRD says all jurisdictions of residence and corresponding TINs, if applicable, should be reported.
| Situation | What the guidance says to report |
|---|---|
| One jurisdiction of tax residence | That jurisdiction and its TIN, if applicable |
| More than one jurisdiction of residence | All jurisdictions of residence and the corresponding TIN for each, if applicable |
| A jurisdiction that issues no TIN | Not addressed in the material cited here |
The quoted guidance says “if applicable” but the cited facts do not resolve what a particular applicant should enter when no TIN has been issued; ask the financial institution and check its current official instructions.
What this guidance does not settle
Three limits follow from the source itself.
It does not determine your tax residence. The cited IRD sentences concern declaration and TIN reporting; this article does not assess the substantive residence tests for your case.
It is jurisdiction-bound. This is Hong Kong's AEOI implementation. Other jurisdictions publish their own forms, their own residence tests and their own TIN rules; nothing on this page governs them, and no conclusion about another jurisdiction's requirements should be drawn from it.
It produces no individual answer. No person's tax residence can be derived from these two sentences. A declaration is a statement given to an institution, and the institution is the party the guidance describes as doing the verifying.
How to check your own position
Open the IRD page linked above. Find the section on residency for tax purposes and TIN. Read the sentence on what the institution may request. List every jurisdiction where you are resident for tax purposes. Collect the TIN issued for each of those jurisdictions. Mark any jurisdiction for which you hold no TIN. Ask your financial institution how to record that case. Ask a tax adviser to apply the residence tests themselves. Repeat the check when your residence position changes. Keep a copy of the form you signed.
Open conditions worth watching
The cited wording says account holders or controlling persons “may be requested” to provide a self-certification. This article does not verify when that request must be made, how to record a missing TIN, or what format your institution requires. Check the current IRD page and institution instructions.
