Hong Kong Salaries Tax System: Territorial Taxation, Competitive Rates
Hong Kong adopts a territorial source principle of taxation, which means that only income arising in or derived from Hong Kong is subject to tax. This principle applies equally to residents and non-residents alike, making it particularly advantageous for expatriates whose scope of responsibilities spans multiple jurisdictions. In the 2024/25 year of assessment (1 April 2024 to 31 March 2025), the Hong Kong Inland Revenue Department introduced tax adjustments affecting high-income earners while maintaining Hong Kong's reputation as one of the most tax-competitive regions globally.
2024/25 Year of Assessment Tax Rates: Progressive Rates vs. Standard Rate
Hong Kong provides two methods for calculating tax, and taxpayers are automatically charged the lower amount. The Inland Revenue Department calculates the tax under both methods and applies the result that is more favorable to the taxpayer.
Progressive Tax Rates
Progressive tax rates apply to "Net Chargeable Income" after deductions of allowances and allowable expenses:
| Net Chargeable Income | Rate | Tax |
|---|---|---|
| First HK$50,000 | 2% | HK$1,000 |
| Next HK$50,000 | 6% | HK$3,000 |
| Next HK$50,000 | 10% | HK$5,000 |
| Next HK$50,000 | 14% | HK$7,000 |
| Remainder (exceeding HK$200,000) | 17% | 17% of remainder |
Two-Tier Standard Rate Regime
Starting from the 2024/25 year of assessment, Hong Kong introduces a two-tier standard rate regime for high-income earners:
- First HK$5,000,000 of net income (before allowances): taxed at 15%
- Portion exceeding HK$5,000,000: taxed at 16%
Personal Allowances and Deductions

60-Day Rule: Exemption Provision for Short-Term Expatriates
The 60-day rule is one of Hong Kong's most valuable tax provisions for expatriates. It provides a full exemption from Salaries Tax for individuals who work in Hong Kong for not more than 60 days in a year of assessment.
How the 60-Day Rule Works
- Counting Days: The Inland Revenue Department counts your "days of presence" in Hong Kong. Even if you are present in Hong Kong for only part of a day, that day is counted.
- Arrival/Departure Days: The day of arrival and the day of departure are counted as two separate days.
- Full Exemption: If the total number of days ≤ 60 days, all employment income for that year is exempt from Hong Kong Salaries Tax.
Example: Application of the 60-Day Rule
An expatriate makes three business trips to Hong Kong:
- Trip 1: Arrive May 1, depart May 10 (10 days)
- Trip 2: Arrive August 15, depart August 25 (11 days)
- Trip 3: Arrive November 5, depart December 20 (46 days)
Total Days: 10 + 11 + 46 = 67 days. Since this exceeds 60 days, the 60-day rule does not apply. The expatriate must calculate tax using the time apportionment basis instead.
Time Apportionment Basis for Non-Hong Kong Employment Income
For expatriates employed under a non-Hong Kong employment contract who stay in Hong Kong for more than 60 days, only the income attributable to services rendered in Hong Kong is subject to tax. This requires satisfying three conditions:
- Place of Contract: The employment contract was negotiated and entered into outside Hong Kong
- Employer Residence: The employer is resident outside Hong Kong
- Place of Remuneration Payment: The remuneration is paid outside Hong Kong
Time Apportionment Formula
The formula for calculating assessable income is as follows:
Practical Example
Assume an expatriate with the following circumstances:
- Total annual income: HKD 1,200,000
- Days in Hong Kong: 120 days
- Total days in year of assessment: 365 days
Calculation: HKD 1,200,000 × (120 ÷ 365) = HKD 394,521 (Assessable Income)
Only HKD 394,521 is subject to Hong Kong Salaries Tax. The remaining HKD 805,479 (attributable to services rendered outside Hong Kong) is exempt.
Hong Kong Employment vs. Non-Hong Kong Employment
Hong Kong Employment Rules
For a Hong Kong employment (where the contract is negotiated/enforceable in Hong Kong, the employer is a Hong Kong resident, or remuneration is paid in Hong Kong), all employment income is subject to tax, regardless of where the services are rendered. However, an exemption for income attributable to services rendered outside Hong Kong may be claimed if the following conditions are met:
- Services are rendered outside Hong Kong for more than 60 days during the year of assessment
- Tax of substantially the same nature has been paid overseas on that portion of income
Tax Filing Requirements and Deadlines
Expatriates must file an annual tax return and apply for exemptions on an annual basis:
- Tax Return Issuance: Early May each year
- Standard Filing Deadline: Approximately 1 month from the date of issuance (usually early June)
- Extended Deadline: Can be applied for through a tax representative
- Record Retention Period: Supporting documents must be kept for 7 years
Practical Tips for Expatriates
Essential Supporting Documents
Maintain detailed records properly to support exemption or time-apportionment claims:
- Travel itineraries, boarding passes, and passport entry/exit stamps
- Daily work schedules documenting service locations
- Employment contracts and amendment documents
- Payroll records indicating where remuneration is paid
- Proof of overseas tax payments (for claiming foreign tax credits)
Comprehensive Double Taxation Agreements
Hong Kong has signed Comprehensive Double Taxation Agreements with more than 45 tax jurisdictions. These agreements prevent the same income from being double-taxed in Hong Kong and your country of residence. Key treaty partners include Mainland China, Singapore, the United Kingdom, Japan, and several European countries.
✅ Key Takeaways
- Hong Kong's territorial source principle of taxation only taxes income derived from Hong Kong, benefiting expatriates with cross-regional responsibilities.
- The 60-day rule provides a full exemption for short-term visitors, but requires careful calculation of the number of days stayed.
- The time apportionment method allows income from non-Hong Kong employment to be taxed only on the portion related to Hong Kong.
- Progressive tax rates (2%–17%) or standard tax rates (15%/16%) ensure that most taxpayers enjoy a lower effective tax rate.
- Proper documentation and timely tax filing are crucial—all claims must be submitted annually via the tax return.
- Mandatory Provident Fund (MPF) contributions of up to HK$18,000 are tax-deductible, providing additional tax relief.
- Comprehensive Double Taxation Agreements (CDTAs) prevent the same income from being double-taxed.
Hong Kong's Salaries Tax system remains one of the most competitive tax regimes in the world, particularly beneficial for expatriates who know how to leverage the 60-day rule and time apportionment provisions. By maintaining accurate records, understanding the distinction between Hong Kong and non-Hong Kong employment, and utilizing various allowable deductions, expatriates can optimize their tax positions while ensuring full compliance with Hong Kong tax regulations.
