How to Register a Startup in Hong Kong: A Step-by-Step Guide for Founders

Hong Kong’s Companies Registry recorded 1,445,767 local companies on its register as of December 2024, a net increase of 22,076 from the prior year, according to the Registry’s annual report. This net growth, however, masks a sharper dynamic for new incorporations: the 2024 Budget announced a HK$100 million allocation over three years to expand the “BUD Fund” and “SME Export Marketing Fund” specifically for startups, while the New Capital Investment Entrant Scheme (CIES), relaunched in March 2024, has already attracted over 600 applications as of Q1 2025, many linked to new business formations. For founders operating in a jurisdiction where the corporate tax rate caps at 16.5% and no capital gains tax exists, the procedural barrier to entry remains low—HK$1,545 in government fees and a single-day electronic filing window through the e-Registry. Yet the 2025-2026 regulatory cycle introduces material changes: the Companies (Amendment) Ordinance 2024, effective 31 December 2024, mandates that all companies maintain a Significant Controllers Register (SCR) with expanded disclosure obligations, and the Inland Revenue Department (IRD) has tightened its transfer pricing documentation requirements for small enterprises under the new two-tiered profits tax regime. This guide provides the exact steps, costs, and statutory references required to incorporate a private limited company in Hong Kong, structured for founders who need compliance certainty from day one.

Choosing the Right Corporate Structure

Private Company Limited by Shares: The Default for Startups

Section 11 of the Companies Ordinance (Cap. 622) defines a private company as one whose articles restrict the right to transfer shares, limit the number of members to 50, and prohibit any invitation to the public to subscribe for shares or debentures. This structure is the standard vehicle for seed-stage and venture-backed startups in Hong Kong for three reasons: limited liability for shareholders, a flat profits tax rate of 8.25% on the first HK$2 million of assessable profits (under the two-tiered regime introduced in 2018), and flexibility in share structure. The Companies Registry charges HK$1,545 for incorporation (HK$1,295 for the application fee plus HK$250 for the business registration fee), and the process can be completed electronically via the e-Registry within 24 hours if all documents are in order. Founders should note that the Business Registration Ordinance (Cap. 310) requires a separate Business Registration Certificate, issued by the IRD for HK$2,150 per year, which must be displayed at the registered office.

Branch Office vs. Subsidiary for Foreign Founders

Non-resident founders face a choice between incorporating a Hong Kong subsidiary or registering a branch office under Part 16 of Cap. 622. A branch office is not a separate legal entity—the foreign parent retains unlimited liability for all Hong Kong operations. Data from the Companies Registry indicates that as of 2024, only 1,847 non-Hong Kong companies were registered as branch offices, compared to over 140,000 companies with foreign shareholding incorporated as local subsidiaries. The subsidiary structure is preferred for tax planning: the two-tiered profits tax rate applies only to locally incorporated companies, and the IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 60 explicitly treats dividends from a Hong Kong subsidiary to a foreign parent as exempt from Hong Kong profits tax, provided the parent does not carry on business in Hong Kong. For founders from Mainland China, the BVI or Cayman Islands holding company structure—a standard offshore-onshore stack—adds a layer of asset protection and facilitates future offshore fundraising, though the Hong Kong subsidiary must comply with the Companies (Directors’ Report) Regulation (Cap. 622D) for group accounts.

The Role of the Company Secretary and Registered Office

Section 474 of Cap. 622 requires every company to appoint a company secretary. If the secretary is an individual, they must ordinarily reside in Hong Kong; if a corporate body, it must have its registered office or place of business in Hong Kong. The same section prohibits a sole director from also serving as the company secretary. For startups, the practical implication is that the registered office—which must be a physical address in Hong Kong, not a P.O. Box—serves as the legal address for service of process and all IRD correspondence. Virtual office providers in Central and Wan Chai charge between HK$2,000 and HK$6,000 per year for a registered address and mail forwarding, though the IRD’s eTAX system now accepts electronic correspondence for companies that register for the service. Founders should budget for this cost as a fixed monthly line item from incorporation day.

Step-by-Step Incorporation Process

Step 1: Name Approval and Reservation

The Companies Registry operates a free online name search service through the Integrated Companies Registry Information System (ICRIS). Under Section 100 of Cap. 622, a name is prohibited if it is identical to an existing company name on the register, or if the Chief Executive considers its use to be a criminal offence or contrary to the public interest. The Registry processed 1,245,000 name searches in 2024, with an average rejection rate of 3.2% due to identical or confusingly similar names. Founders should prepare three alternative names in order of preference, as the electronic application allows real-time name checking before submission. The name reservation, once approved, is valid for 60 days.

Step 2: Filing the Incorporation Form (NNC1)

The core filing document is Form NNC1, available electronically through the e-Registry portal. This form requires:

• Proposed company name (in English, Chinese, or both)
• Nature of business (a brief description; no SIC code required)
• Registered office address (physical Hong Kong address)
• Details of at least one director (individual or corporate; Section 453 of Cap. 622 requires at least one individual director)
• Details of the company secretary
• Details of at least one shareholder (the initial subscriber)
• Share capital structure: par value per share (commonly HK$1.00), number of shares issued (minimum 1), and total amount

The filing fee is HK$1,545. For paper applications, the fee is HK$1,720, and processing takes 4-7 working days. The electronic filing, by contrast, typically yields a Certificate of Incorporation within 24 hours. As of 2025, the e-Registry accepts payment by PPS, Visa, Mastercard, or UnionPay.

Step 3: Issuance of Certificate of Incorporation and Business Registration

Upon approval, the Companies Registry issues a Certificate of Incorporation (Form NR1) and a Business Registration Certificate (Form BR1) simultaneously. The certificate contains the company number (an 8-digit number starting with the prefix for the year of incorporation), the date of incorporation, and the company name. The Business Registration Certificate is valid for one year from the date of issue, and the IRD will send a renewal notice approximately one month before expiry. The current annual fee for business registration is HK$2,150, though the 2024-25 Budget waived the levy for the first year of new registrations.

Step 4: Post-Incorporation Compliance

Within 18 months of incorporation, the company must hold its first Annual General Meeting (AGM) under Section 610 of Cap. 622. The first set of audited financial statements must be filed with the Companies Registry within 9 months of the end of the financial year (or 6 months for listed companies, though this guide addresses private companies). For startups with annual revenue below HK$10 million, the Hong Kong Institute of Certified Public Accountants (HKICPA) allows simplified audit procedures under the Small and Medium-sized Entity (SME) Financial Reporting Framework, but an audit is still mandatory unless the company qualifies for exemption under Section 359 of Cap. 622—which requires that the company has no turnover, no assets, and no liabilities for the entire financial year. In practice, this exemption is rarely applicable to operating startups.

Taxation and Compliance for Startups

The Two-Tiered Profits Tax Regime

The Inland Revenue Ordinance (Cap. 112) imposes profits tax at 16.5% for corporations. However, the two-tiered regime, effective from the year of assessment 2018/19, reduces the rate to 8.25% on the first HK$2 million of assessable profits. This concession applies only to one nominated enterprise within a group of connected entities. For a standalone startup, the tax saving is HK$165,000 per year—HK$2 million × (16.5% - 8.25%). The IRD’s 2024 annual report shows that 93,400 corporations claimed this concession in the 2022/23 assessment year, with total tax savings of HK$15.4 billion. Founders must file a Profits Tax Return (Form BIR51) within one month of the issue date, though extensions are routinely granted for first-time filers.

Mandatory Audit and Filing Deadlines

Section 122 of Cap. 112 requires every corporation carrying on a trade or business in Hong Kong to keep sufficient records for at least 7 years. For a startup, this means maintaining invoices, receipts, bank statements, and contracts in either English or Chinese. The audit must be conducted by a Certified Public Accountant (CPA) registered with the HKICPA. The filing timeline for a company with a 31 December financial year end is: audit completion by 15 August (9 months after year end) and tax return filing by 15 November (11 months after year end). Late filing attracts a penalty of up to 10% of the tax assessed, plus a surcharge of 5% if payment is overdue by more than 6 months. The IRD issued 1,200,000 estimated assessments in 2024 for late or non-filing, a 12% increase from 2023.

The Significant Controllers Register (SCR)

The Companies (Amendment) Ordinance 2024, effective 31 December 2024, expands the SCR requirements under Part 6A of Cap. 622. All companies must now identify and record “significant controllers”—individuals who directly or indirectly hold more than 25% of the shares or voting rights, or who otherwise exercise significant control over the company. The register must be kept at the registered office and made available to law enforcement upon request. For startups with multiple co-founders, this means documenting the beneficial ownership of any nominee shareholders or trust structures. Failure to maintain the SCR is a criminal offence, punishable by a fine of up to HK$250,000 and imprisonment for up to 2 years.

Banking and Fundraising for Newly Incorporated Entities

Opening a Corporate Bank Account

Hong Kong’s three largest retail banks—HSBC, Standard Chartered, and Bank of China (Hong Kong)—have tightened their Know Your Customer (KYC) procedures since the HKMA’s 2019 circular on anti-money laundering (AMC/2019/1). For a newly incorporated startup, the minimum documentation required includes: Certificate of Incorporation, Business Registration Certificate, Memorandum and Articles of Association, board resolution authorising the account opening, proof of registered office address, and identification documents for all directors and ultimate beneficial owners. The HKMA reported in its 2024 Annual Report that the average account opening time for a corporate entity was 12 business days, down from 18 days in 2022, but startups with non-resident directors or complex shareholding structures may face delays of 4-8 weeks. Virtual banks such as ZA Bank and Livi Bank offer faster onboarding—typically 3-5 business days—but impose lower transaction limits (often HK$1 million per day) and require a minimum initial deposit of HK$10,000.

Fundraising Structures: SAFEs, Convertible Notes, and Equity

Hong Kong law does not have a statutory framework for Simple Agreements for Future Equity (SAFEs), which originated in Delaware. Instead, founders typically use convertible loan notes governed by Hong Kong law, with conversion triggered by a qualified financing round (commonly HK$10 million or more). The Securities and Futures Commission (SFC) regulates the offer of securities under the Securities and Futures Ordinance (Cap. 571). Section 103 of Cap. 571 prohibits any invitation to the public to acquire securities unless the offer is made through a licensed intermediary or falls within an exemption. For seed-stage fundraising, the “professional investor” exemption under Section 103(3)(k) is most relevant: offers may be made to individuals whose net worth exceeds HK$8 million (or HK$40 million for corporations) without a prospectus. The SFC’s 2024 consultation paper on tokenised securities (CP-2024-12) indicates that the regulator is considering extending these exemptions to digital securities, but as of Q1 2025, no formal amendments have been gazetted.

The Role of Incubators and Government Grants

The Hong Kong Science and Technology Parks Corporation (HKSTP) offers the IDEATION Programme, which provides up to HK$100,000 in seed funding for proof-of-concept projects, and the INCUBATION Programme, which provides up to HK$1,290,000 over 24 months. Cyberport’s Creative Micro Fund (CMF) provides HK$100,000 per startup, and its Incubation Programme offers up to HK$500,000. The Innovation and Technology Commission’s (ITC) Technology Start-up Support Scheme for Universities (TSSSU) allocates up to HK$1.5 million per university project. All these programmes require the applicant to be a Hong Kong-registered company for at least 3 months. The 2024-25 Budget increased the ITC’s funding for the Incubation Programme by 15% to HK$460 million, reflecting the government’s stated target of incubating 3,000 startups by 2027.

1. File Form NNC1 electronically through the e-Registry at HK$1,545 to obtain incorporation within 24 hours, and budget HK$2,150 annually for the Business Registration Certificate renewal.
2. Designate a Hong Kong resident company secretary and a physical registered office address before filing, as both are statutory requirements under Sections 474 and 658 of Cap. 622.
3. Claim the two-tiered profits tax rate of 8.25% on the first HK$2 million of assessable profits by filing a timely Profits Tax Return (Form BIR51) and engaging a HKICPA-registered auditor for annual accounts.
4. Maintain a Significant Controllers Register from day one, documenting all shareholders holding more than 25% of shares or voting rights, to comply with the Companies (Amendment) Ordinance 2024.
5. Raise seed capital through convertible loan notes under the professional investor exemption (Section 103(3)(k) of Cap. 571), targeting investors with net worth exceeding HK$8 million, and apply for HKSTP or Cyberport incubation programmes within 3 months of incorporation.
