Key Takeaways
Every Hong Kong company must appoint a statutory auditor. The only full exemption is for dormant companies with zero accounting transactions during the year.
The Big Four (EY, PwC, Deloitte, KPMG) are the right choice for listed companies, IPO-stage businesses, and complex regulated entities.
Mid-tier firms like BDO, Baker Tilly, and RSM offer credible international-standard audits at more flexible pricing and are a better fit for most private companies.
Typical statutory audit fees for a small HK company range from HKD 8,000 to HKD 20,000 per year. Record quality is the biggest variable in that range.
Most Hong Kong SMEs approaching their first statutory audit don't need a Big Four firm, but they don't know that yet. Choosing a firm that's too large for your stage means paying premium fees for resources you won't use, while a firm that's too small may lack the standing your investors or bankers expect. Getting this call wrong isn't catastrophic, but it creates friction that compounds over time.
The question we hear most from founders approaching their first year-end is 'Which type of firm actually makes sense for a company like mine?' This guide answers that question.
We've ranked the top 10 audit firms in Hong Kong across two tiers, Big Four and mid-tier, and added a practical decision section that maps company type and size to the right tier. Use the summary table below to orient quickly, then read the profiles for the firms most relevant to your situation.
Research disclosure: This guide is based on research conducted in March 2026, including a review of each firm's official website, publicly available firm profiles, independent employee reviews on Glassdoor, and user reviews on Trustpilot where available. All competitor data is sourced and dated. Review scores were accurate at the time of research and may have changed.

How We Ranked These Audit Firms
We ranked each firm against five-criteria: reputation, Hong Kong market presence, industry specialisation, suitability for private companies, and service scope.
Here’s what we looked at:
- Reputation: industry standing, global network affiliation, and published recognition
- Market presence: number of listed companies audited and visibility in the Hong Kong market
- Industry specialisation: demonstrated experience in sectors relevant to SMEs and cross-border operations
- Suitability for private companies: service flexibility, responsiveness, and ability to support small to mid-sized businesses
- Service scope: availability of tax, advisory, and compliance support alongside core audit services
Tier 1: Big Four Audit Firms
The Big Four, EY, PwC, Deloitte, and KPMG, are the dominant global accounting and advisory networks. In Hong Kong, they audit the majority of listed companies and serve as the default choice for multinational subsidiaries, IPO candidates, and heavily regulated businesses. Their fee structures reflect this.
If your company is privately held, below HKD 100M in revenue, and not preparing for a public listing, the Big Four are almost certainly not the right fit. This is not because the quality isn't there, but because you'd be paying for depth and infrastructure you don't need.

Notable Mention: HLB Hodgson Impey Cheng
HLB Hodgson Impey Cheng is a Hong Kong CPA firm and a member of HLB International, a global network of accounting firms ranked in the top 8 internationally. Founded in 1983, the firm ranks among the top six auditors of listed companies in Hong Kong by client count.
HLB is a strong alternative for companies that need a firm with strong listed-company credentials at mid-tier pricing. It did not make our top 10 ranking because it is less commonly selected by private SMEs, but it is worth including on your shortlist if you have near-term listing ambitions.
Which Tier Is Right for Your Company?
The decision isn't about quality. All firms in this ranking follow ISA and are regulated by HKICPA or the Accounting and Financial Reporting Council (AFRC). It's about fit: who will actually engage with your business at the level it needs, and at a cost that makes sense.
| Your situation | Recommendation | Why |
|---|---|---|
| Listed company or preparing for HK/US listing | Big Four | Regulatory credibility, investor recognition, and reporting accountant capability |
| MNC subsidiary in HK — parent requires Big Four sign-off | Big Four | Parent company policy often mandates Big Four globally |
| Private company, revenue HKD 50M–500M, no listing plans | Mid-tier (BDO, RSM, Forvis Mazars) | International-standard audit at significantly lower cost than Big Four |
| SME, revenue under HKD 50M, straightforward operations | Mid-tier (Baker Tilly, Grant Thornton, SW CPA) | Personalised service, direct partner access, practical pricing |
| Cross-border group with operations in Mainland China | Grant Thornton or Forvis Mazars | Strong Greater China and regional expertise in both firms |
| Growth-stage company with IPO as a 3–5 year goal | RSM or HLB | IPO preparation capability without Big Four pricing, useful transitional choice |
| Company with ESG or sustainability reporting obligations | Forvis Mazars | Sustainability reporting is a core service line, not an add-on |
A common mistake is choosing a firm based on name recognition and then paying a premium for capacity that never gets used. Most private Hong Kong companies do not need a Big Four auditor. The key test: does your bank, your investors, or your parent company have a view on which firm signs off? If not, your decision is about fit, price, and relationship quality.
What Does a Statutory Audit Cost in Hong Kong?
Most audit firms do not publish their fees. Pricing is typically quote-based and depends on several factors. The ranges below are based on market practice as of 2025/26, consistent with publicly available fee guides from Hong Kong CPA firms.
| Company profile | Typical annual audit fee (HKD) | Key cost drivers |
|---|---|---|
| Very small private company with minimal transactions, single entity | HKD 8,000–15,000 | Clean bookkeeping is the biggest lever |
| Small SME with moderate transaction volume, straightforward structure | HKD 15,000–30,000 | Reconciliation complexity, record quality |
| Mid-sized company with higher volume, multi-currency, some subsidiaries | HKD 30,000–80,000 | Group structure, jurisdiction count, IFRS requirements |
| Complex or regulated business with significant transactions, listed or near-listed | HKD 80,000–200,000+ | Regulatory requirements, investor reporting, Big Four pricing tier |
The most controllable variable is your bookkeeping quality. Auditors charge more when they have to spend additional time reconciling messy records, chasing missing documentation, or correcting classification errors. A company with clean, well-organised books will typically pay less than a comparable company with disorganised records, even with the same firm.
Most mid-tier firms will offer a fixed-fee engagement for straightforward SME audits. The Big Four rarely offer fixed fees. Their engagements are priced on scope and billed on time.
Statutory Audit Requirements in Hong Kong
Under the Companies Ordinance (Cap. 622), every company incorporated in Hong Kong must prepare audited financial statements each year. There is no revenue threshold or size exemption that removes this obligation for active companies.
Who must be audited?
All active Hong Kong companies must have their financial statements audited annually by an independent external auditor.
Who is exempt?
The only full exemption from the audit requirement under Cap. 622 is for dormant companies — companies with zero accounting transactions during the financial year. A company must pass a special resolution declaring dormancy and notify the Companies Registry.
Important: There is a separate 'reporting exemption' (SME-FRS) under the Companies Ordinance that allows small private companies to prepare simplified financial statements if they meet two of three criteria: total revenue below HKD 100M, total assets below HKD 100M, and fewer than 100 employees. This simplifies the financial reporting standard. It does not remove the audit requirement. All companies using SME-FRS must still appoint a statutory auditor.
Who can sign the audit?
The auditor must be a Certified Public Accountant (CPA) holding a valid practising certificate from the Hong Kong Institute of Certified Public Accountants (HKICPA). All firms in this ranking meet this requirement.
What is the audit used for?
- Submitted with your Profits Tax Return (PTR) to the Inland Revenue Department (IRD) as part of annual tax filing
- Required by your company secretary for the annual general meeting
- Needed if you are claiming offshore tax exemption for income sourced outside Hong Kong
- Required by most banks for business account reviews or loan applications
For details on the Companies Ordinance audit requirements, see the Companies Registry FAQ.
Tips for Choosing the Right Audit Firm
Most firms on this list will produce a technically compliant audit. The difference lies in how they engage with your business, how they communicate, and how well they understand the operational context behind your accounts.
- Industry experience: An auditor who knows trading company accounting, cross-border supplier payment structures, or digital services revenue recognition will ask better questions and spot issues faster. Ask firms how many clients in your industry they currently serve.
- Clear communication and realistic timelines: Before signing, ask the firm to walk you through their typical engagement process: what they need from you, when they need it, and how long the field work takes. Firms like Baker Tilly and Grant Thornton are consistently noted in employee and client reviews for direct and responsive communication.
- Transparent pricing: Ask for a fixed-fee proposal if your accounts are straightforward. For mid-tier firms, this is standard practice. If a firm is only willing to quote on a time-and-materials basis for a simple audit, treat that as a yellow flag.
- Scalability: If you are planning to expand, raise capital, or list in the next three to five years, factor in whether the firm can grow with you. RSM, HLB, and the Big Four are better positioned for the IPO readiness journey than smaller local practices.
- Timing and availability: Audit firms get booked out during peak season (typically March–August in Hong Kong, when year-ends cluster). Start the selection process at least two to three months before your financial year-end to avoid rushed engagements and limited firm availability.
Make Audits Easier with a Statrys Business Account
In Hong Kong, annual audits are mandatory for most companies, but a smooth audit starts long before your auditor arrives. At Statrys, we see a consistent pattern: companies that come into audit season with clean, well-reconciled accounts pay less and finish faster than those with disorganised records.
The most common friction points are mixed business and personal transactions, unreconciled FX payments, and missing documentation for international transfers. All of which are preventable.
A Statrys Business Account is built for companies that operate across currencies and borders. It keeps your finances organised from day one:
- Separate business and personal transactions automatically, often the most basic audit-readiness step
- Xero integration syncs your transactions for bookkeeping without manual reconciliation
- Real-time SWIFT payment tracking and approval workflows, full audit trail for international transfers
- Multi-currency accounts in HKD, RMB, USD, EUR, and more, no spreadsheet consolidation needed
- Full transaction history with user role controls, clean records for your auditor and your company secretary
Over 10,000 businesses use Statrys to manage their Hong Kong finances. 96% of clients open their accounts within 3 business days.

FAQs
Do all companies in Hong Kong need to appoint an audit firm?
Yes. Every active company incorporated in Hong Kong must have its financial statements audited annually by an independent CPA holding a valid practising certificate from the HKICPA. The only exemption is for dormant companies, companies with zero accounting transactions during the year, which must pass a special resolution and notify the Companies Registry to claim this status.
