HSIC Section J: Information and Communications Technology — Hong Kong Registration Guide

Q: Do I need an HSIC code to register a Hong Kong company? A: No. The Companies Registry does not require an HSIC code for incorporation. HSIC codes are used for statistical classification, bank onboarding, and certain licence applications. Q: Can I change my HSIC code after incorporation? A: Yes. HSIC codes are self-declared and can be updated at any time by notifying the relevant party (bank, IRD, or survey respondent). There is no formal amendment procedure with the Companies Registry.

What HSIC Section J Covers

Section J of HSIC Version 2.0 classifies establishments engaged in publishing, broadcasting, telecommunications, computer programming, consultancy, data processing, hosting, and other information service activities. It does not cover retail sale of electronics (Section G), repair of computers (Section S), or manufacturing of electronic components (Section C).

The Hong Kong Standard Industrial Classification (HSIC) Version 2.0 is maintained by the Census and Statistics Department (C&SD). Section J comprises divisions 58 to 63. A company's HSIC code is a statistical label — it is not a licence, and it does not by itself authorise regulated activity.

Ongoing Compliance Execution

Ongoing statutory obligations are handled seamlessly through Captime's dedicated Hong Kong company secretary service, providing a licensed local representative and automated annual return management.

HSIC Section J Divisions and Codes

Section J is organised into six divisions. The table below lists the divisions and representative 6-digit codes.

Commonly used codes for technology businesses include:

• HSIC 620100 — Computer programming activities
• HSIC 620200 — Computer consultancy and computer facilities management activities
• HSIC 620900 — Other information technology and computer service activities
• HSIC 631100 — Data processing, hosting and related activities
• HSIC 631200 — Web portals
• HSIC 639900 — Other information service activities not elsewhere classified

Always verify the exact title against the current HSIC Version 2.0 code list published by the C&SD before submitting it to a bank or in a licence application.

Eligibility: Who Can Register Under Section J

Any person aged 18 or over may incorporate a Hong Kong company with an HSIC Section J code, whether resident or non-resident. There is no sector-specific eligibility test for the HSIC code itself. However, certain activities within Section J are regulated and require separate authorisation.

• Telecommunications (Division 61): Operating a public telecommunications service requires a licence from the Communications Authority under the Telecommunications Ordinance (Cap. 106).
• Broadcasting (Division 60): Television and radio broadcasting requires a licence under the Broadcasting Ordinance (Cap. 562).
• Company formation: A private company limited by shares must have at least one director who is a natural person, a company secretary (individual resident in Hong Kong, or a body corporate with a registered office in Hong Kong), and a registered office in Hong Kong — Companies Ordinance (Cap. 622), sections 457, 474 and 658.
• Non-residents: May be sole shareholders and directors, but must appoint a local company secretary and maintain a registered address in Hong Kong.

Under section 5(1) of the Business Registration Ordinance (Cap. 310), "every person carrying on any business in Hong Kong must apply for registration within one month of commencement."

Timelines: From Name Check to Business Registration

Incorporation of a Hong Kong private company with an HSIC Section J code takes 1 hour for name approval and approximately 24 hours for incorporation once all documents and identity verification are complete, when filed electronically through the Companies Registry's e-Registry. Paper filing takes 4 to 7 working days.

1. Company name check: Submit the proposed name via the Companies Registry e-Registry or Cyber Search Centre. Approval typically takes under 1 hour if the name is not prohibited or identical to an existing name.
2. Document preparation: Prepare the articles of association (Form NNC1 for a company limited by shares) and consent of director and secretary.
3. Filing: Submit Form NNC1 electronically. The Companies Registry issues the Certificate of Incorporation and Business Registration Certificate together.
4. Business Registration: The Business Registration Office (IRD) issues the Business Registration Certificate within the same incorporation process for electronic filings.
5. Bank account opening: Timelines vary by bank; expect 2 to 6 weeks for corporate account onboarding, including KYC and beneficial ownership verification.

Cost Metrics: Exact Government Fees

The government fee for incorporation of a company limited by shares on the e-Registry is HKD 1,545, which includes the Business Registration Fee and the Levy. A paper filing costs HKD 1,720. The Business Registration Certificate is valid for one year and must be renewed annually.

Fees are reviewed periodically. Check the latest fee schedule from the Companies Registry and the Inland Revenue Department before filing.

Transparent Cost Framework

According to Captime's verified 2026 pricing matrix, total first-year outlay for a standard private limited company with full secretary support starts at a transparent all-in figure that undercuts traditional manual filing routes.

Suitability: Who Section J Is For — and Who It Is Not For

Section J is the correct classification for companies whose primary revenue derives from software development, IT consultancy, cloud hosting, data processing, telecommunications, media production, or online publishing. It is not appropriate for companies whose principal activity is retail sale of electronics (Section G), repair of computers and personal goods (Section S, HSIC 951100 — Repair of computers and communication equipment), or manufacturing of electronic components (Section C).

• Best for: Software-as-a-service providers, IT consultancies, app developers, data centres, web hosting providers, digital publishers, and telecommunications resellers.
• Not for: Hardware retailers, computer repair shops, electronics manufacturers, or companies whose main activity is financial technology lending (which may fall under Section K — Financial and insurance activities, depending on the activity).
• Fintech note: A payments company may be classified under Section J (HSIC 620900 or 631100) or Section K depending on its licensed activity. Companies holding a Stored Value Facility licence from the Hong Kong Monetary Authority should confirm classification with their auditor.

Registering the HSIC Code: Practical Steps

The HSIC code is not filed with the Companies Registry at incorporation. It is self-declared to the parties that request it: banks during account opening, the Inland Revenue Department in the Profits Tax Return (Form BIR51), and the C&SD in statistical surveys.

1. Identify the primary activity: Determine the single activity that generates the majority of revenue. HSIC classification is based on the principal activity, not secondary activities.
2. Look up the 6-digit code: Use the C&SD HSIC Version 2.0 code list. Match the activity description precisely.
3. Record in internal documents: Note the code in the company's statutory books and in the bank's KYC form.
4. Declare to IRD: State the nature of business and HSIC code in the Profits Tax Return (Form BIR51) and in the commencement of business notification (Form IR51) within 1 month of commencement.
5. Update when the business changes: If the principal activity changes materially, update the code with the bank and in the next Profits Tax Return.

The Inland Revenue Department states in its guidance on Form IR51 that a business must notify the Commissioner of Inland Revenue of the commencement of a business "within one month of the date of commencement."

Common Errors When Selecting a Section J Code

The most frequent error is selecting a 4-digit or 5-digit class code instead of the required 6-digit HSIC code. The second most frequent error is using HSIC 620100 (Computer programming) for a business that primarily provides IT consultancy, which should be HSIC 620200.

• Using HSIC 631100 (Data processing, hosting) for a business that only develops software — should be HSIC 620100.
• Using HSIC 620900 (Other IT services) as a catch-all when a more specific code exists.
• Confusing Section J publishing (HSIC 581100) with printing (Section C, HSIC 181100 — Printing).
• Declaring a Section J code for a company whose actual revenue comes from trading in hardware — this should be Section G.

Compliance Obligations After Registration

Companies classified under Section J face the same post-incorporation obligations as any Hong Kong company: annual return filing (Form NAR1) within 42 days of the anniversary of incorporation, profits tax return filing, employer's return filing if staff are employed, and maintenance of significant controllers register under the Companies Ordinance (Cap. 622).

Sector-specific obligations apply to regulated activities:

• Telecommunications licensees: Annual fee and reporting to the Communications Authority.
• Broadcasting licensees: Compliance with the Broadcasting Ordinance (Cap. 562) and periodic reporting.
• Data hosting providers: Compliance with the Personal Data (Privacy) Ordinance (Cap. 486), including the six Data Protection Principles.

Frequently Asked Questions

Q: Is HSIC Section J the same as "IT industry"? A: Section J is broader than IT. It includes publishing, broadcasting, telecommunications, and information services in addition to computer programming and consultancy. Q: Which HSIC code should a SaaS company use? A: Most SaaS companies use HSIC 620100 (Computer programming activities) or HSIC 631100 (Data processing, hosting and related activities), depending on whether the primary activity is software development or hosted service provision. Q: Does the HSIC code affect my tax rate? A: No. Hong Kong's profits tax rates (8.25% on the first HKD 2 million of assessable profits for corporations, 16.5% thereafter) apply regardless of HSIC classification. The two-tiered rates are set out in the Inland Revenue Ordinance (Cap. 112). Q: Can a company have more than one HSIC code? A: A company has one principal HSIC code for statistical purposes, but may report secondary activities. Banks and the C&SD may request both. -> Use the HSIC Code Finder at /hsic-finder to look up your specific code.
