Hong Kong's Inland Revenue Department (IRD) administers profits tax under the Inland Revenue Ordinance (IRO). The framework is well-established and relatively straightforward for most SMEs.
Two-tiered rates (2025/26 Year of Assessment):
- 8.25% on the first HKD 2,000,000 of assessable profits
- 16.5% on assessable profits above HKD 2,000,000
- Only one connected entity in a group can claim the lower rate
Offshore profits exemption โ for profits that genuinely arise outside Hong Kong. The IRD tests whether: (a) the company carries on a trade, profession, or business in Hong Kong; (b) the profits in question arose in or were derived from Hong Kong. If operations are genuinely conducted outside Hong Kong (foreign clients, foreign contracts negotiated abroad, services performed abroad), an offshore claim can be supported. The IRD may investigate and request evidence โ business records, contracts, communications, director travel records โ to verify the claim. A successful claim results in 0% tax on the offshore portion.
The FSIE regime (Foreign-Sourced Income Exemption, in force since 1 January 2023, expanded 1 January 2024) introduced a significant change for MNE entities โ members of multinational enterprise groups. Four categories of passive income received in Hong Kong by MNE entities are now subject to profits tax unless a relevant exception applies: interest, dividends, equity disposal gains, and IP income. To claim exemption, the entity must meet an economic substance requirement (maintain adequate staff and operating expenditure in Hong Kong), a participation exemption (for dividends and equity disposal gains), or a nexus requirement (for IP income).
Critically, the FSIE regime does not affect most SMEs and small non-resident founders โ it targets MNE groups. A standalone Hong Kong Limited owned by an individual founder, with no group structure, is generally not an "MNE entity" for FSIE purposes. If you have a more complex structure (Hong Kong holding company + foreign subsidiaries), professional advice on FSIE is essential.
No separate capital gains tax. Gains from disposal of capital assets are generally outside profits tax, but the capital-versus-revenue distinction matters. Do not assume a share or asset sale is exempt without reviewing its facts.
Mandatory annual statutory audit. A Hong Kong private limited company must generally have its financial statements audited annually by a Hong Kong Certified Public Accountant, regardless of size. A company that has formally become dormant under the Companies Ordinance is the key exception. The audited accounts support the Profits Tax Return; budget for them from year one unless the company will remain formally dormant.
Key compliance obligations:
- File the Profits Tax Return (BIR51) when issued โ the stated deadline and any valid extension govern the filing date
- Submit audited financial statements with the Profits Tax Return
- File Annual Return (Form NAR1) with the Companies Registry within 42 days of the incorporation anniversary โ filing fee HKD 105 if on time
- Renew Business Registration Certificate annually โ HKD 2,200 for a 1-year certificate; HKD 5,950 for 3-year (levy waived for 2025-2026 year)
- Maintain statutory registers (directors, shareholders, significant controllers)
- Notify the Companies Registry of any changes to directors, shareholders, or registered address within prescribed timeframes
Budget for HKD 8,000โ30,000/year for a small active company covering company secretary, registered address, bookkeeping, audit, and tax return filing. The audit is the dominant cost driver for small companies.
