Every Hong Kong limited company is required to complete an annual audit, a fundamental procedure no company can avoid. Whether your business is in its early stages or expanding, audit remains indispensable for tax filing, financial disclosure, and building external trust. This guide breaks down the audit report, the audit procedure, statutory requirements, and key considerations for selecting a qualified auditor.
What Is an Audit Report? A Quick Overview of the Basics
An Audit Report is a statutory document issued annually by an independent Certified Public Accountant (CPA). It verifies that a company’s financial statements, including the income statement, balance sheet, cash flow statement, and statement of changes in equity, are true, accurate, and compliant with applicable accounting standards. Every limited company must appoint a qualified auditor each year to examine its accounts and issue a professional opinion.
Investors, banks, and business partners rely on the audit report to assess a company’s financial position. Beyond statutory compliance, it is a critical instrument for establishing external credibility, especially when applying for credit facilities, corporate financing, or considering a public listing.

Why Do Companies Need an Audit? 3 Core Areas of Value
Auditing is not simply a statutory procedure. It directly impacts a company’s financing ability, operational performance, and management decisions. The value lies in 3 key areas:
1. Helping Investors and Banks Make Informed Judgements
Whenever financing is required, investors are being brought in, or credit facilities are being applied for, the other party will evaluate the company’s risk profile, profitability, and financial soundness through the audit report. For external stakeholders, it is the most credible form of financial evidence.
2. Enhancing Financial Transparency and Credibility
Non-profit organisations, chambers of commerce, and family-run businesses all use audited financial statements to demonstrate governance standards. Audited financial data also carries greater comparability and credibility than unaudited information.
3. Identifying Financial Errors and Internal Control Risks at an Early Stage
Auditors examine transaction records, source documents, cash flows, and internal control procedures. Any errors, missing documentation, or potential fraud risks are identified and addressed promptly, allowing businesses to make corrections before they affect tax or compliance obligations.
When Does a Hong Kong Company Need to Complete an Audit Report?
A Hong Kong limited company must generally complete its Audit Report within 9 months after the financial year-end to meet the Profits Tax Return filing deadline. The company must then file its Annual Return with the Companies Registry the following month (private companies are generally not required to submit financial statements with the Annual Return).
Since April 2023, the IRD has adopted a stricter approach to Profits Tax Returns. As long as a company has income, audited financial statements and the tax computation are typically required to be submitted together with the Profits Tax Return each time, not only at initial filing.
Categories of Companies That May Apply for the Reporting Exemption
Under the Companies Ordinance (Cap. 622), companies meeting the qualifying criteria may enjoy an exemption or simplified arrangement in relation to the preparation and filing of financial reports and directors’ reports. There are 3 eligible categories:
1. Small Private Company
A small private company or small guarantee company satisfying at least 2 of the following 3 criteria may use simplified financial statements (SME-FRF/SME-FRS):
- Revenue ≤ HK$100 million
- Total assets ≤ HK$100 million
- Number of employees ≤ 100
Note: The reporting exemption does not waive the audit requirement. Financial statements must still be audited.
2. Eligible Private Company
A small private company or small guarantee company satisfying at least 2 of the following 3 criteria may use simplified financial statements (SME-FRF/SME-FRS):
- Revenue ≤ HK$100 million
- Total assets ≤ HK$100 million
- Number of employees ≤ 100
Note: The reporting exemption does not waive the audit requirement. Financial statements must still be audited.
3. Small / Eligible Company Groups and Other Circumstances
Groups comprising small private companies, small guarantee companies, or eligible private companies may also qualify, provided the entire group meets the size criteria and does not fall within excluded categories such as banks or insurance companies.
When Are Tax Returns Due? A Full Explanation of N / D / M Codes
The IRD generally issues Profits Tax Returns (BIR51 / BIR52) on the first working day of April each year. Companies must file within one month of the date of issue. Electronic filing (e-Tax) grants an automatic one-month extension.
N Code Companies (Accounting Year-End: 1 April to 30 November)
Bulk extensions are generally not available.
- Standard deadline: 2 May of the following year
- Electronic filing: 2 June of the following year
D Code Companies (Accounting Year-End: 1 December to 31 December)
Extensions to mid-August are available via the Block Extension Scheme through a tax representative.
- Standard deadline: 15 / 29 August of the following year
- Electronic filing: 15 / 29 September of the following year
M Code Companies (Accounting Year-End: 1 January to 31 March)
- With assessable profits: 2 November / 2 December of the following year
- With adjusted loss: 2 February of the following year (2 March for electronic filing)
Newly Incorporated Companies
New companies generally receive their first Profits Tax Return (BIR51) approximately 18 months after incorporation and must submit their first audited financial statements at that time. The initial filing is typically granted a 3-month submission window and is not eligible for the N / D / M bulk extension scheme.
(The above deadlines apply to the 2025/26 Year of Assessment only. Subsequent years’ deadlines are as specified in the IRD’s annual circular.)
Which Companies Are Exempt from the Annual Audit?
Only 2 categories may qualify for an audit exemption under company law:
1. Dormant Company
Under the Companies Ordinance (Cap. 622), a company that formally passes a special resolution and registers with the Companies Registry as a dormant company may be exempt from preparing and submitting an audit report during dormancy. Once any accounting transaction is resumed, dormant status is immediately void.
2. Branch Offices of Overseas Companies Established in Hong Kong
A branch office is not a separate legal entity and is generally not required to prepare local statutory audit reports. Whether an exemption applies depends on whether the branch is subject to an equivalent audit regime in its home jurisdiction and the IRD’s specific requirements. Not all branches are automatically exempt.
Even if a company has had no revenue for an extended period, as long as it remains an active Hong Kong limited company, it must still maintain accounts, complete the audit, and file tax returns.
Consequences of Failing to Complete the Audit on Time
Under the Inland Revenue Ordinance, failing to file tax returns or submit required documents without reasonable excuse may result in a maximum fine of HK$10,000 and a surcharge of up to 3 times the tax undercharged. The IRD may also issue estimated assessments or initiate a tax investigation. In the long run, delayed audits can damage a company’s reputation and increase difficulties in obtaining bank financing.
Full Breakdown of the Audit Procedure: 5 Key Steps
All audit work is conducted in accordance with the Hong Kong Standards on Auditing (HKSA), based on financial statements prepared under the Hong Kong Financial Reporting Standards (HKFRS).
Step 1: Year-End Closing and Accounts Preparation
Confirm the financial year-end date and complete basic accounting work, including recording income and expenses, reconciling bank accounts, and organising invoices, receipts, and contracts.
Step 2: Submission of Documents to the Auditor and Risk Assessment
Provide the auditor with draft financial statements, the general ledger, and key contracts. The auditor will assess the company’s business model and internal controls, plan the audit approach, and issue an audit checklist of documents required.
Step 3: Audit Procedures and Substantive Testing
The auditor performs sampling tests, issues confirmation letters to banks, customers, and suppliers, reviews material contracts and board resolutions, and assesses inventory valuations, bad debt provisions, and asset depreciation to ensure financial statements give a true and fair view.
Step 4: Audit Adjustments and Management Response
If errors or non-compliant items are found, the auditor will propose adjustments. If management declines and the discrepancy is material, the auditor may issue a qualified opinion or other modified audit opinion.
Step 5: Issuance of the Audit Report and Use for Tax Filing
The auditor issues the final Audit Report. Directors and shareholders review and approve the financial statements. The signed audit report is then submitted to the IRD together with the Profits Tax Return.
Essential Document Checklist Before the Audit
Corporate Registration and Structural Documents
Business Registration Certificate, Certificate of Incorporation, Articles of Association, latest Annual Return, register of directors and shareholders, board and shareholders’ meeting minutes, and records of material resolutions.
Financial and Operational Documents
Having the following information prepared in advance for the audit year will make the audit procedure significantly smoother. These include but are not limited to:
- Complete accounting records for the audit year: general ledger, subsidiary ledgers, trial balance, and opening and closing balances
- Draft financial statements prepared by management (income statement, balance sheet, cash flow statement, etc.)
- Full-year bank monthly statements and bank reconciliation statements
- Sales invoices, receipts, and other income documentation
- Purchase invoices, expense receipts, and other expenditure vouchers
- Major contracts: leases, client and supplier contracts, loan and guarantee documents
- Payroll and Mandatory Provident Fund (MPF) records and employment contracts
- Profits Tax Returns for the current and prior years (if applicable) and prior years’ audited financial statements

How to Choose the Right Auditor
Under Hong Kong law, audit reports must be signed by a practising accountant recognised by the HKICPA. Companies can verify credentials on the Institute’s website. Key criteria for selection:
Licence and Professional Qualifications
The auditor must be a Certified Public Accountant (Practising) registered with the HKICPA. An accountant without a practising certificate is not legally permitted to provide audit services.
Whether Industry Experience Is Relevant
An auditor with relevant industry experience will grasp your financial model more quickly and identify the risk areas that truly matter.
Whether Fees Are Clear and Transparent
A professional auditor will clearly outline the base fee, additional charges for higher transaction volumes, and whether work such as consolidated accounts, special reports, or XBRL conversion is included.
Whether the Auditor Can Support the Company's Long-Term Growth
For companies planning to raise investment, apply for bank financing, or undertake equity restructuring, an auditor with relevant transactional experience can provide higher-level advice and help identify compliance or tax risks in advance.
Frequently Asked Questions
Can a company prepare its own accounts and audit report?
A company may handle bookkeeping in-house or outsource it. However, the audit report must be signed by a local practising accountant with a valid practising certificate. It cannot be self-issued or signed by an unqualified person.
Does an "inactive company" need to complete an audit and file taxes?
Yes. A company with no business activity but still in normal operation must still maintain accounts, complete the audit, and file taxes. Only a formally registered dormant company may waive audit obligations during dormancy.
How long does the audit procedure typically take?
For a typical SME with organised accounts and complete documentation, the audit procedure takes approximately 4 to 6 weeks. First-time audits, high transaction volumes, or complex structures may extend this timeline.
When does a newly incorporated company need to complete its first audit?
Approximately 18 months after incorporation, when the first Profits Tax Return is received. Companies typically set their first accounting period to end within 12 to 18 months after incorporation to allow sufficient time for the first audit and tax filing.
What happens if errors or discrepancies are found during the audit?
The auditor will request supplementary documents or accounting adjustments. If the issues are significant and management declines to adjust, the auditor may include a qualified opinion or emphasis of matter paragraph in the audit report, and recommend improvements to internal controls and bookkeeping processes.
