Annual return, BR and audit: three clocks that founders mix up
Three separate obligations, three separate dates, one company.
Why the dates collide
A Hong Kong company’s recurring compliance looks like one job, but it is three: the annual return to the Companies Registry, the Business Registration certificate from the IRD’s Business Registration Office, and the audit and profits tax return. Each runs on its own date, set by a different event — and missing one does not move the others.
What triggers each date
| Obligation | Authority | Clock starts from | Timing |
|---|---|---|---|
| Annual return | Companies Registry | Anniversary of incorporation | Within 42 days after each anniversary (private company) |
| Business Registration | IRD — Business Registration Office | Certificate validity period | Renew before the 1-year or 3-year certificate expires |
| Audit + profits tax return | Auditor / IRD | Financial year-end and date of return issue | First return usually issued ~18 months after incorporation; deadlines stated on the return |
Late delivery of an annual return attracts higher registration fees and can lead to prosecution. A lapsed Business Registration certificate is an offence in itself. A late profits tax return can lead to penalties and an estimated assessment.
Setting up the year
Fix the financial year-end
Choose an accounting reference date that suits the business and the auditor’s calendar. It drives the audit timetable.
Diary the incorporation anniversary
The annual return falls due 42 days after it, every year, regardless of the financial year-end.
Diary the BR expiry
The renewal demand is normally sent before expiry, but responsibility for renewing sits with the company.
Book the auditor early
Audit work needs complete books. Engage the auditor before year-end, not after the tax return arrives.
Keep the company secretary in the loop
The secretary usually prepares the annual return and keeps the statutory registers — including the SCR — up to date.
How founders get caught
- Assuming the accountant files everything — the annual return is often the secretary’s job, not the auditor’s.
- Changing address without notifying — notices go to the registered office.
- A dormant period with no books — the audit still needs records.
- Director or shareholder changes not filed with the Registry within the statutory time.
- SCR left blank after a share transfer.
- Treating BR as a one-off rather than a renewable certificate.
Questions readers ask
When is a Hong Kong company’s annual return due?
For a private company, within 42 days after the anniversary of its date of incorporation each year.
Is Business Registration renewal automatic?
No. The Business Registration Office normally issues a renewal demand, but the company is responsible for renewing and displaying a valid certificate.
Does a small or dormant company need an audit?
Hong Kong companies generally need audited financial statements. A company that has resolved to be dormant under the Companies Ordinance is treated differently, but dormancy has conditions — check before relying on it.
When does the first profits tax return arrive?
For a new company, typically around 18 months after incorporation. The deadline is stated on the return.
