Compliance and incorporation playbook
Licences and regulatory approvals
No sector-specific licence is mapped to this classification. Standard incorporation, business registration and the general compliance calendar below still apply, and premises-based or product-based permits can apply case by case. Emerhub confirms the exact licensing position during scoping.
Offshore profits claim feasibility
LowThis activity typically requires physical presence in Hong Kong for repairs and maintenance. Contracts are often negotiated with local clients, making it difficult to qualify for offshore treatment. The services are inherently tied to the local market and regulatory environment.
Profits Tax Return deadlines under the Block Extension Scheme
With Emerhub as your tax representative, the filing deadline for the Profits Tax Return (BIR51) extends far beyond the standard one month, depending on your accounting year-end. A 31 December year-end extends the filing to August of the following year.
| Year-end | IRD code | Without representative | With Emerhub as tax rep |
|---|---|---|---|
| 1 April to 30 November | N | Within 1 month of return issue | No block extension: early May of the following year |
| 1 December to 31 December | D | Within 1 month of return issue | Mid-August of the following year |
| 1 January to 31 March | M | Within 1 month of return issue | Mid-November of the same year |

MPF enrolment for employees
Employers enrol every Hong Kong employee aged 18 to 64 employed for 60 days or more in an MPF scheme. Employer and employee each contribute 5% of relevant income, capped at HKD 1,500 per month each. Emerhub administers MPF enrolment and monthly contributions under its payroll service.

Annual audit with SME reporting exemption
Every Hong Kong company files audited financial statements; there is no small-company audit exemption as in Singapore. Small private companies meeting any two of revenue at or below HKD 100 million, assets at or below HKD 100 million, or 100 or fewer employees qualify for the reporting exemption and prepare simplified accounts under the SME Financial Reporting Standard, which lowers audit preparation cost. Emerhub structures client accounts under the reporting exemption wherever the criteria are met.
