Year-end accounting, audit preparation, and tax filing are core parts of running a compliant business in Hong Kong.
Accurate year-end records help businesses:
For many companies, the year-end process involves coordinating accounting records, audit preparation and Profits Tax Return filing within a relatively short timeframe.
For Hong Kong companies, year-end compliance runs on three connected workstreams:
The business prepares or finalises its financial records for the relevant accounting period.
This may include:
Most Hong Kong incorporated companies are generally required to prepare audited financial statements unless they have properly declared dormant status under the Companies Ordinance.
Audit preparation usually involves organising supporting documents, reconciling key balances and responding to auditor requests.
A profit tax return (formally, the Profits Tax Return, Form BIR51 for corporations) must be filed with the IRD together with audited financial statements, a tax computation, and supporting schedules.
The IRD generally requires returns to be filed within one month of issue, although block extension arrangements are commonly available through tax representatives. E-filing may provide an additional extension in applicable cases.
The documents required will depend on the company’s business model and internal accounting processes.
Having these records organised early can make the audit and tax filing process more efficient.
In most cases, yes. Hong Kong incorporated companies are generally required to prepare audited financial statements unless they have properly declared dormant status. This is why audit preparation remains an important part of the annual compliance cycle for most active companies.
For tax and auditing, Hong Kong applies the same rule to companies of all sizes. Even small private companies that use the simplified SME reporting framework must still have their accounts audited.
Companies that are uncertain about their audit obligations should review their status carefully before assuming an exemption applies.
Dormant companies may be exempt from certain audit and reporting requirements if dormant status has been properly declared under Hong Kong company law.
For businesses that are no longer trading, dormancy may reduce the compliance burden. However, companies should ensure that dormant status has been formally established and remains appropriate for their circumstances.
A private company becomes dormant by delivering a special resolution to the Companies Registry under section 5 of Cap. 622. The IRD accepts tax returns from properly declared dormant companies without audited accounts.
Yes. Hong Kong companies can choose their financial year end under the Companies Ordinance (Cap. 622). The chosen date determines their accounting period, audit schedule and tax filing deadlines.
There is no fixed financial year end for companies. Three dates should be distinguished:
Company financial year: Set by the directors and can end on any date.
Government financial year: Runs from 1 April to 31 March, matching the tax year of assessment.
Annual return date: Based on the incorporation anniversary, with Form NAR1 due within 42 days.
Two common options are:
31 December (Code D): Suitable for companies reporting to overseas parent companies or following a calendar year.
31 March (Code M): Aligns with Hong Kong's tax year and offers the longest block extension for tax filing.
Companies may also choose 30 June or 30 September, but both fall under Code N, which has no block extension.
The first financial year can be shorter or longer than 12 months but cannot exceed 18 months from incorporation. Subsequent periods are normally 12 months.
Directors can change the financial year end by resolution, subject to Companies Registry requirements. The revised accounting period must not exceed 18 months. Public companies and companies limited by guarantee must also file Form NAC4 within 15 days.
No separate notification to the Inland Revenue Department is required. The revised date is reflected in the audited financial statements submitted with the profits tax return.
The exact filing timetable will depend on the company’s accounting date, the issue date of the return, and whether a tax representative is handling the filing.
As a general rule:
Because deadlines and filing mechanics can change, businesses should confirm the applicable timetable for the relevant year of assessment before filing.
A more efficient year-end process usually depends on preparation well before the filing deadline.
Practical steps include:
Early preparation can reduce pressure on finance teams and lower the risk of delays during audit or tax filing.
