Choosing the right accounting firm for your Hong Kong business matters because the market spans global networks, mid-tier CPA firms, and digital-first compliance platforms — and not every provider offers the full range of accounting and compliance services. Most SMEs approaching their first comprehensive accounting engagement do not need a Big Four firm. Many founders only discover that after gathering quotes and finding that a poor fit adds cost and delay with banks, investors, or the Inland Revenue Department.
Key Takeaways
- Big Four accounting firms (Deloitte, PwC, EY, KPMG) primarily serve listed companies, multinational corporations, and financial institutions; employees typically undergo rigorous training and the networks carry strong regulatory knowledge for complex financial reporting.
- Mid-tier accounting firms balance cost and quality for growing businesses and the middle market, delivering accounting, tax, and advisory services, while registered audit firms provide statutory audits when a Big Four mandate does not apply.
- Digital-first accounting services with cloud accounting, flexible pricing, and bundled corporate secretarial support suit Hong Kong SME founders who want remote compliance in one workflow, with audit coordinated separately when required.
Which Are the Best Accounting Firms in Hong Kong?
No single accounting firm is best for every Hong Kong company. Hong Kong accounting firms split into Big Four networks, mid-tier international firms, and integrated platforms, each with different accounting service offerings ranging across auditing, tax, and advisory services. Under Cap. 622, most active private companies need maintained books, audited financial statements, a Profits Tax Return, and corporate secretarial filings each year; confirm which outputs a shortlisted firm actually covers before comparing fees.
If you want daily compliance in one workflow and can accept audit via a partner firm, an integrated platform fits; if the same accounting firm must sign the statutory audit and financial statements, shortlist AFRC-registered mid-tier or Big Four practices. Understanding corporate accounting obligations in Hong Kong helps narrow this list before comparing individual providers. Below is a list of top accounting firms in Hong Kong to get you started.
Firm | Tier | Core services | Stand-out focus | Best for | Typical cost tier |
|---|---|---|---|---|---|
| Osome | Integrated platform | Bookkeeping, Profits Tax, corp sec, incorporation, payroll | Ecommerce integrations, remote onboarding, streamlined compliance | Foreign founders, ecommerce SMEs, startups needing efficient accounting | Moderate |
| Deloitte | Big Four | Audit, tax, advisory, deals | Comprehensive audit and advisory for complex reporting | Listed companies, multinationals needing statutory audit | Premium |
| PwC | Big Four | Audit, tax, deals, risk consulting | Expertise in audit and financial reporting for regulated sectors | Large corporations, regulated industries needing audit | Premium |
| EY | Big Four | Audit, tax, ESG, strategy | ESG assurance and risk advisory alongside audit | Multinationals and regulated businesses with advanced audit | Premium |
| KPMG | Big Four | Audit, tax, forensic, transfer pricing | Forensic accounting and regulatory audit expertise | Financial institutions and large groups needing audit | Premium |
| BDO | Mid-tier | Statutory audit, tax, advisory, outsourcing | International audit standards with flexible service | Mid-sized private and cross-border companies needing audits | Mid-range |
| Baker Tilly | Mid-tier | Audit, bookkeeping, tax, corporate finance | Partner-led audit and advisory focused on family businesses | Local SMEs and family businesses needing personalised audit | Mid-range |
| Grant Thornton | Mid-tier | Audit, tax, cross-border advisory, IPO support | Regional audit and advisory for Greater China mid-market | HK–Mainland operators and mid-market companies needing audits | Mid-range |
This curated shortlist is only for your reference, and should not be regarded as a strict ranking. You should take your company's size, compliance requirements, and growth stage into consideration when making the final choice.
How We Selected These Accounting Firms
Choosing an accounting firm involves more than comparing prices. We evaluated each provider based on the services they offer, the types of businesses they support, and their ability to help companies meet Hong Kong's ongoing compliance requirements.
Our assessment considered the following criteria:
- Service offering: Availability of bookkeeping, tax compliance, payroll, company secretarial services, statutory audit, and business advisory.
- Business suitability: Whether the firm is best suited to startups, SMEs, international businesses, ecommerce companies, or large enterprises.
- Industry expertise: Experience supporting businesses across different industries, including cross-border operations and regulated sectors.
- Technology and efficiency: Use of cloud accounting platforms, automation, online collaboration, and digital workflows to simplify financial management.
- Market reputation: Established presence in Hong Kong, professional qualifications, global network (where applicable), and publicly available client feedback.
Rather than assigning numerical scores, we focus on helping businesses identify the type of accounting firm that best matches their size, operational complexity, and long-term growth plans.
This comparison is based on publicly available information, including firms' official websites, service offerings, pricing where disclosed, professional registrations, and publicly available customer reviews where applicable. Information was reviewed in July 2026 and may change over time.

Integrated Accounting Platform
Integrated accounting platforms combine bookkeeping, tax compliance, payroll, and company secretarial services into a single digital solution. They streamline ongoing financial management through cloud-based tools, while statutory audits are typically coordinated with external audit partners. This model is well suited to startups, SMEs, and international founders seeking efficient, technology-driven compliance.
Osome
Osome Hong Kong combines an AI-enabled platform with professional accountants for company formation through ongoing compliance. Osome has served more than 40,000 businesses globally; its Hong Kong-based accounting services use cloud accounting and flexible pricing to improve financial visibility for founders who prefer a digital-first model over a traditional firm-based office.
Key services
- Ecommerce reconciliation across Shopify, Amazon, and payment gateways.
- Remote company formation, registered address, and company secretary filings.
- Cloud bookkeeping with compliance calendar, document vault, and activity-based pricing.
- Profits Tax filing, tax compliance support, and Inland Revenue Department correspondence.
- Payroll, MPF contributions, and payslip administration with IRD-ready reporting.
- Statutory audit coordination through AFRC-registered partner audit firms when required.
Pros & cons
Strengths | Limitations |
|---|---|
| End-to-end compliance in one workflow | Primarily designed for startups and SMEs, not ideal for large enterprises with complex needs |
| Remote onboarding and English-language support for foreign founders | Not suited to listed companies requiring Big Four audit mandates |
| Transparent, activity-based pricing for SMEs | Core scope centres on recurring SME compliance rather than bespoke project advisory |
Typical fees
Published packages start from HK$ 3,500/y (Operate), with Grow at HK$ 4,200/y and Scale at HK$ 10,188/y; payroll and historical catch-up are add-ons. Statutory audit is quoted separately through partner firms, so total annual spend depends on both platform tier and audit scope.
Best for:
- Foreign founders
- Ecommerce SMEs
- Tech startups and freelancers
- Growth-stage companies needing all-in-one compliance
Big Four Accounting Firms
The Big Four firms — Deloitte, PwC, EY, and KPMG — primarily serve listed companies, multinational groups, financial institutions, and businesses with complex reporting requirements. While they offer comprehensive audit, tax, and advisory services, they are generally more expensive than providers focused on SMEs.
Deloitte
Deloitte Hong Kong is a Big Four member with 3,000+ professionals across Hong Kong and Macau, focused on large corporations, financial institutions, and cross-border groups since 1972. Like other Big Four accounting firms, Deloitte invests in rigorous staff training and deep capital markets and Hong Kong Stock Exchange listing work.
Key services
- Statutory audit for listed issuers and licensed financial institutions under HKFRS and IFRS.
- Hong Kong IPO, SPAC, and secondary listing advisory with Hong Kong Stock Exchange filing support.
- TMT and financial services teams covering fintech licensing and prudential reporting.
- Transfer pricing and cross-border tax for mainland-Hong Kong and Greater Bay Area structures.
- Cyber risk, regulatory compliance, and Omnia-enabled forensic analytics.
Pros & cons
Strengths | Limitations |
|---|---|
| Largest Big Four network by global revenue | Premium fees; often cost-prohibitive for micro-SMEs |
| Deep TMT, financial services, and cross-border expertise | Less personalised service model for small private companies |
| Advanced audit analytics and risk capabilities | Peak-season capacity constraints for lower-complexity engagements |
Typical fees
Quote-based only; mandated or complex Big Four engagements often exceed HK$ 80,000. Micro-SMEs without a mandate rarely receive fixed-fee quotes; bookkeeping and corp sec, if needed, are billed separately from audit.
Best for:
- Listed companies and multinationals
- Mandated Big Four appointments (loan, shareholder, group policy)
PwC
PwC Hong Kong is among the city's largest audit practices by revenue, with strength in financial statements, IFRS financial reporting, and capital markets work for corporates preparing to list on the Hong Kong Stock Exchange.
Key services
- Audit of banks, asset managers, and insurers under SFC and HKMA prudential frameworks.
- HKEX Main Board and GEM listing compliance and sponsor-facing audit support for Hong Kong Stock Exchange issuers.
- IFRS 9 and IFRS 17 for treasury-heavy corporates and complex instruments.
- Mainland outbound structures, red-chip arrangements, and VIE-related reporting.
- Deals and transaction services for inbound M&A and post-merger integration in Asia-Pacific.
Pros & cons
Strengths | Limitations |
|---|---|
| Rigorous audit methodology and IFRS depth | Premium pricing structured for large engagements |
| Strong in banking, capital markets, healthcare, and real estate | Limited flexibility for early-stage startups with simple accounts |
| Global integration for multinational group reporting | Consumer-facing review scores do not reflect corporate audit quality |
Typical fees
Quote-based on scope and time; regulated or group reporting sits well above the HK$ 8,000–20,000 band typical of straightforward mid-tier SME audits. Sponsors and lenders sometimes name PwC specifically during IPO or facility documentation.
Best for:
- Large corporates and financial institutions
- IPO-stage and complex group reporting
EY
EY Hong Kong is a Big Four network strong in regulated sectors, ESG financial reporting, and advisory services for organisations that need assurance alongside risk management and internal control reviews.
Key services
- ESG assurance and ISSB-aligned sustainability reporting.
- Life sciences, healthcare, and pharmaceutical regulatory audit.
- Strategy and transactions for carve-outs, joint ventures, and regional HQ relocations.
- Indirect tax, customs, and supply-chain structuring for APAC trading groups.
- Internal controls, SOX-style testing, and risk management for regional hubs.
Pros & cons
Strengths | Limitations |
|---|---|
| Broad service coverage across assurance and advisory | Enterprise-focused model; limited SME personalisation |
| Global reach for multi-jurisdiction groups | High fee structure disproportionate for routine compliance |
| Credibility with regulators and institutional investors | Less practical for standalone bookkeeping engagements |
Typical fees
Quote-based with no public SME tariff; multinationals and regulated sectors pay for complexity. Routine private-company audit work is usually cheaper through mid-tier firms unless an investor or listing pathway requires EY by name.
Best for:
- Multinationals and regulated businesses
- ESG, risk, and IPO-grade audit needs
KPMG
KPMG Hong Kong is a Big Four member with depth in banking, insurance, energy, forensic investigations, and transfer pricing for Greater China operations.
Key services
- Banking, insurance, and wealth-management regulatory audit under HKMA, IA, and SFC frameworks.
- Transfer pricing documentation and BEPS compliance for trading and holding companies.
- Forensic accounting, fraud investigations, and dispute advisory support.
- Tax planning, tax compliance, and green finance advisory under Hong Kong sustainable finance initiatives
- Deal advisory and corporate finance for inbound acquisitions in the region.
Pros & cons
Strengths | Limitations |
|---|---|
| Strong regulatory credibility in financial services | Premium fees vs mid-tier alternatives |
| Consistent global audit methodology | Large-client focus can feel impersonal for SMEs |
| Sector depth in banking, insurance, and energy | Scheduling pressure during peak audit season |
Typical fees
Quote-based; financial services and forensic mandates carry premium pricing. Simple trading SMEs without regulatory complexity are usually better served by mid-tier fixed-fee quotes in the HK$ 8,000–20,000 audit range.
Best for:
- Financial institutions and large corporates
- Banking and insurance prudential reporting
- Forensic and complex regulatory audits
Mid-Tier Accounting Firms
Mid-tier firms bridge the gap between boutique practices and the Big Four. They provide statutory audits, tax, accounting, and advisory services while often offering a more personalised approach and pricing suited to growing businesses and SMEs.
BDO
BDO Hong Kong is the Hong Kong member of BDO Limited, the fifth-largest global accounting network, with 1,000+ staff and a strong mid-tier track record for private companies and cross-border groups.
Key services
- Group audit coordination across BDO's 160+ country network.
- HKFRS and IFRS conversion for mainland enterprises preparing to list or invest offshore.
- Family office, private wealth, and owner-managed group advisory.
- Outsourced finance function, outsourcing services, and management reporting for growing SMEs.
- Restructuring, debt advisory, and forensic support for mid-market disputes.
Pros & cons
Strengths | Limitations |
|---|---|
| International audit standards without Big Four pricing | Less depth in highly regulated niche sectors (e.g. biotech, fintech) |
| Strong track record with mid-sized private and cross-border companies | Fees still above boutique firms for simple engagements |
| Flexible service model with partner involvement | Resource constraints during busy audit periods |
Typical fees
Quote-based; BDO often offers fixed-fee statutory audits for straightforward private companies. Active SME audits typically fall between HK$ 15,000 and HK$ 30,000 depending on record quality and cross-border complexity; outsourced bookkeeping adds to the total.
Best for:
- Mid-sized private and cross-border companies
- Bank-mandated auditor (non-Big Four)
- HK holding companies with overseas subsidiaries
Baker Tilly Hong Kong
Baker Tilly Hong Kong is an independent member of Baker Tilly International with a Hong Kong presence since 1977, offering a more flexible service model and partner-led support for local businesses and family-owned private companies.
Key services
- Partner-led statutory audit with direct access for owner-managed private companies.
- Family business succession, business consulting, and corporate finance advisory.
- Retail, hospitality, and professional services sector audits with management reporting.
- Fast-track audit for SMEs with moderate transaction complexity.
- Cross-border tax for Hong Kong SMEs with ASEAN or Taiwan trading links.
Pros & cons
Strengths | Limitations |
|---|---|
| Hands-on, direct partner access for SMEs | Fewer international resources than BDO or RSM Hong Kong for complex group audits |
| Practical, compliance-focused audit work | Limited coverage for specialised industries (financial services, biotech) |
| Faster turnaround than Big Four for private companies | More flexible service model but smaller workforce vs largest mid-tier firms |
Typical fees
Quote-based with fixed-fee options for owner-managed SMEs. Straightforward audits often sit in the HK$ 8,000–20,000 band when records are clean; partner-led service may sit toward the middle of that range.
Best for:
- Local SMEs and owner-managed companies
- Partner-led tax and audit (not capital markets)
Grant Thornton Hong Kong
Grant Thornton Hong Kong is part of the Grant Thornton global network, with a Hong Kong office integrated into a broader Greater China practice for cross-border mid-market work.
Key services

- Manufacturing, logistics, and consumer supply-chain audits.
- R&D tax incentives and mainland-Hong Kong transfer pricing.
- Transaction support, valuation, and restructuring for mid-market M&A.
Pros & cons
Strengths | Limitations |
|---|---|
| Practical Greater China and regional cross-border insight | Network structure can mean variation across offices |
| Scalable advisory alongside core audit | Less depth in ultra-niche sectors (fintech, biotech) |
| Strong fit for logistics, manufacturing, and consumer products | Brand recognition below Big Four with some international investors |
Typical fees
Quote-based; Grant Thornton commonly packages mid-market audit and tax for cross-border SMEs. Indicative fees for operators with mainland links often range from HK$ 15,000 to HK$ 40,000 depending on entity count, inventory, and transfer-pricing complexity.
Best for:
- HK–Mainland operators
- Regional expansion and pre-IPO SMEs
- Similar profile to Forvis Mazars Hong Kong (verify AFRC)
How Much Do Accounting Services Cost in Hong Kong?
The cost of accounting services in Hong Kong depends on your company's size, transaction volume, and the level of support you require. While some businesses only need bookkeeping and tax filing, others may also require payroll, company secretarial services, or a statutory audit. Understanding what is included in a provider's quote makes it easier to compare firms on value rather than price alone.
Service package | Typical scope | Typical annual cost |
|---|---|---|
| Basic accounting | Bookkeeping, preparation of financial statements, Profits Tax filing | HK$ 8,000–20,000 |
| Accounting + company secretary | Accounting, tax compliance, corporate secretarial services | HK$ 15,000–35,000 |
| Integrated platform | Cloud bookkeeping, tax filing, payroll or company secretarial services, with audit coordinated through a partner | HK$ 12,000–30,000+ |
| Mid-tier local firms | Accounting, tax, statutory audit, and advisory capabilities | HK$ 15,000–30,000+ |
| Big Four firm or large international firms | Audit, tax, and advisory for large or complex organisations and global firms | From HK$ 80,000 |
The figures above are indicative market ranges and may vary depending on the complexity of your business, transaction volume, and the scope of services required.
What affects the cost?
Several factors influence the fees charged by accounting firms, including:
- Business size and transaction volume, as companies with higher activity or a global presence typically require more bookkeeping and reporting work.
- Industry and business complexity, particularly for businesses with overseas operations, multiple entities, or regulated activities.
- Service scope, such as whether you require bookkeeping alone or a bundled solution that includes payroll, tax compliance, and company secretarial services.
- Statutory audit requirements, since audit fees are often quoted separately and depend on the quality of your accounting records.
- Technology and service model, with cloud-based providers often offering fixed-fee packages, while traditional firms may charge based on time spent or customised engagements.
When comparing professional services firms, don't focus solely on the quoted price. Check exactly which services are included, whether audit fees are separate, and whether ongoing compliance support — such as bookkeeping, tax filing, payroll, and company secretarial services — is bundled into the package.

How Should a Business Choose the Right Accounting Firm?
Match scope to your stage first — who maintains the books, who signs the audit, who files Profits Tax, and whether a financial reporting council is needed — then compare tier and quotes.
Define scope and check credentials
List your four annual outputs under Cap. 622: books, audited statements, Profits Tax, and corp sec. An integrated platform fits if one team can handle daily compliance and audit runs through a partner; if the same firm must sign the report, shortlist AFRC-registered mid-tier or Big Four practices.
When comparing firms, check:
- Scope fit across bookkeeping, tax services, corp sec, and audit
- AFRC registration and Hong Kong Institute of Certified Public Accountants (HKICPA) standing
- Industry fit and cross-border coverage
- Fee transparency and engagement letter scope
Match firm tier to your situation
Osome’s integrated platform provides tailored solutions for foreign founders, remote operations, ecommerce businesses with multi-channel sales, tech startups, freelancers, and private SMEs that need bookkeeping, Profits Tax, and corporate secretarial services handled efficiently in one place.
Revisit the shortlist if revenue, investor requirements, or cross-border structure changes materially.
Compare quotes and appoint
Request itemised quotes from two or three firms, using the scenario ranges above as a baseline — record quality often moves the fee more than revenue. Big Four mandates usually come from loan covenants, investor letters, group policy, or IPO sponsors, not company size alone.
Shortlist one to two months after year-end; peak demand runs March to August. Confirm AFRC registration, sign an engagement letter, and deliver trial balances. Straightforward SME audits take six to twelve weeks once records are ready.
How Osome Can Help
Managing separate providers for audits, tax, and corporate compliance creates yearly friction and workflow gaps, even with sound records.
Osome combines bookkeeping, tax filing, a compliance calendar, and accountant support in one platform, with statutory audit coordinated through registered partners when required. Explore Osome Hong Kong accounting packages for scope and pricing.
Summary
The decision that saves the most time and money is usually scope, not brand: confirm who maintains the books, who signs the audit, and who files Profits Tax before comparing firm names. Many founders appoint an auditor first, then pay again when poor records fail review — monthly bookkeeping quality drives audit cost more reliably than tier choice. Treat AFRC registration and a written engagement scope as fixed filters, shortlist before March peak season, and revisit tier when a loan covenant or funding round introduces new external requirements.
