Hong Kong Country-by-Country Reporting (CbCR)
Understand OECD BEPS Action 13, Hong Kong notification and return requirements, and how we help multinational groups coordinate data and filings.
Typical group threshold
EUR 750m / HKD 6.8bn
Preceding accounting period; test depends on the ultimate parent jurisdiction and applicable rules.
Notification
Generally 3 months
After the accounting period ends; a qualifying group notification arrangement may apply.
CbC Return
Generally 12 months
After period end, or earlier if stated in an assessor's notice.
What is Country-by-Country Reporting?
CbCR is an OECD BEPS Action 13 transparency requirement. Large multinational enterprise groups disclose revenue, profit or loss before tax, taxes, employees, capital, tangible assets and constituent-entity activities by tax jurisdiction. Authorities use the information to assess transfer-pricing and BEPS risks; it does not itself determine tax payable.
Who is in scope?
Hong Kong's CbCR regime generally applies to reportable multinational groups meeting the consolidated-revenue threshold in the immediately preceding period. Whether a Hong Kong company must notify or file a full return depends on its role and the group's overseas filing and exchange arrangements.
- For a Hong Kong-resident ultimate parent, the stated Hong Kong revenue threshold is HKD 6.8 billion; overseas-parent groups use the threshold applicable to the parent jurisdiction or the relevant EUR 750 million-equivalent test.
- A Hong Kong ultimate parent of a reportable group generally has the primary filing duty.
- Hong Kong subsidiaries of foreign-parent groups may have a secondary filing duty if an overseas filing or exchange condition fails; one qualifying return or surrogate filing can avoid duplication.
- One Hong Kong entity may notify for a reportable group with multiple Hong Kong entities where the legal conditions are satisfied.
Notification vs CbC Return
An overseas parent's submission does not automatically answer every Hong Kong notification question.
| Requirement | What it covers | Typical timing / filing role |
|---|---|---|
| CbCR notification | Identify the group's parent or reporting entity, relevant reporting period and filing arrangement. | Within 3 months after the accounting period; Hong Kong entity or authorized service provider. |
| CbC Return | Jurisdiction-level tax and economic data plus constituent-entity information, submitted in the specified electronic/XML format. | Within 12 months after period-end or earlier deadline in an IRD notice; Hong Kong reporting entity where required. |
| Overseas or surrogate filing | Consider treaty/exchange arrangements and which group entity actually submits. | Evaluate each year; overseas filing does not automatically remove notification responsibilities. |
When businesses ask for help
Typical matters require both group-level and Hong Kong-entity analysis.
Several Hong Kong group companies
Coordinate one permitted notification, entity mapping and group reporting responsibilities instead of duplicating work.
New or deregistered entities
Check relevant accounting periods and constituent-entity treatment; inactivity or deregistration is not an automatic exemption.

Frequently asked questions
Does every Hong Kong subsidiary file a full CbC Return?
No. The group's parent, local filing triggers, surrogate filing and automatic-exchange arrangements determine whether a Hong Kong entity files a full return. A notification may still be required.
Does a loss-making or dormant company automatically qualify for exemption?
No. The reporting test operates at multinational group level. Entity activity and changes in status must be reviewed in context.
What e-Cert is required?
Registration and reporting through the CbC Reporting Portal require an e-Cert (Organisational) with AEOI Functions, including for an authorized service provider.
Can HKBSCL submit on our behalf?
Where an appropriate engagement and IRD authorization such as Form IR1465 are in place, an eligible service provider may handle the relevant portal and filing tasks.
