Hong Kong's tax system is built on the territorial source principle: only income with a source in Hong Kong is taxable. This means that employment income earned while physically working in Hong Kong is taxable, while income from employment duties performed outside Hong Kong is generally exempt, even if paid by a Hong Kong employer. This territorial approach is fundamentally different from the worldwide taxation systems of most Western countries.
Determining the "source" of employment income depends on where the employment contract was negotiated and signed, where the employer is resident, and where the employee's duties are performed. For most expats working in Hong Kong under local employment contracts, the Inland Revenue Department (IRD) treats income as Hong Kong-sourced based on where the services are rendered. Days worked outside Hong Kong for business purposes may qualify for time-apportionment relief.
Hong Kong offers two methods of calculating salaries tax, and the IRD automatically applies whichever results in the lower tax:
| Chargeable Income (HKD) | Rate |
|---|---|
| First 50,000 | 2% |
| Next 50,000 (50,001-100,000) | 6% |
| Next 50,000 (100,001-150,000) | 10% |
| Next 50,000 (150,001-200,000) | 14% |
| Remaining (200,001+) | 17% |
A flat rate of 15% is applied to net income (income minus deductions) without personal allowances. The standard rate is beneficial for higher earners whose income pushes them into the top progressive brackets where the effective rate exceeds 15%.
For 2024/25, a two-tiered standard rate applies: the first HKD 5 million of net income is taxed at 15%, and any amount above HKD 5 million is taxed at 16%. This change from the 2023/24 year targets higher-income earners while preserving the 15% rate for most taxpayers.
| Annual Income (HKD) | Tax Under Progressive (with allowances) | Tax Under Standard Rate | Lower |
|---|---|---|---|
| 300,000 | HKD 8,000 | HKD 45,000 | Progressive |
| 600,000 | HKD 44,000 | HKD 90,000 | Progressive |
| 1,200,000 | HKD 146,000 | HKD 180,000 | Progressive |
| 3,000,000 | HKD 452,000 | HKD 450,000 | Standard rate |
| 6,000,000 | HKD 962,000 | HKD 900,000 | Standard rate |
For most expats earning between HKD 300,000 and HKD 2,000,000, the progressive method produces lower tax due to the personal allowance (HKD 132,000 for 2024/25) and the lower initial brackets. Very high earners typically benefit from the standard rate.
Hong Kong provides several allowances that reduce chargeable income before the progressive rates are applied:
| Allowance Type | Amount (HKD, 2024/25) |
|---|---|
| Basic personal allowance | 132,000 |
| Married person's allowance | 264,000 |
| Child allowance (per child) | 130,000 (max 9 children) |
| Single parent allowance | 132,000 |
| Dependent parent/grandparent (60+) | 150,000 each (300,000 if both 60+) |
| Dependent parent/grandparent (55-59) | 75,000 each |
| Disabled dependent | 75,000 |
Deductions are available for specific expenses:
The MPF is Hong Kong's mandatory retirement savings scheme. Most employees and self-employed persons aged 18-65 must participate. Contributions are 5% from the employee and 5% from the employer, each capped at HKD 1,500 per month (HKD 18,000 per year), based on relevant income up to HKD 30,000 per month.
| Monthly Income (HKD) | Employee Contribution | Employer Contribution |
|---|---|---|
| Below 7,100 | 0% | 5% of income |
| 7,100 - 30,000 | 5% of income | 5% of income |
| Above 30,000 | HKD 1,500 (capped) | HKD 1,500 (capped) |
Expats on employment visas must participate in MPF. However, those covered by an overseas retirement scheme that is exempt from MPF requirements (such as a qualifying master trust in the UK or a 401(k) in the US) may be able to apply for exemption. When you leave Hong Kong permanently, you can withdraw your MPF benefits as a lump sum, subject to specific documentation requirements.
Hong Kong's territorial system means many income types common for expats are not taxable:
| Income Type | Taxed in Hong Kong? | Notes |
|---|---|---|
| HK employment salary | Yes | Time-apportioned for overseas work days |
| Foreign employment salary (work done outside HK) | No | Territorial principle |
| Overseas rental income | No | Only HK property is taxed |
| HK property rental income | Yes (Property Tax at 15%) | Net of 20% allowance and rates |
| Dividends (HK and foreign) | No | Dividends are exempt |
| Interest income | Generally no | Most interest is exempt |
| Capital gains (shares, property) | No | No capital gains tax |
| Stock options | Yes (if granted for HK employment) | Taxed on exercise, time-apportioned |
| Pension income | No (if foreign-sourced) | Foreign pensions not taxed |
A unique feature of Hong Kong salaries tax is the two-year election. If you and your spouse both have chargeable income, you can elect to be jointly assessed. This is not joint taxation in the Western sense—each spouse is still taxed individually on their own income. The benefit arises because personal allowances can be allocated between spouses to minimize total tax. For example, if one spouse earns HKD 500,000 and the other earns HKD 100,000, electing joint assessment allows the lower earner's unused allowances to be transferred to the higher earner, potentially reducing the combined tax bill.
Stock options granted in connection with Hong Kong employment are taxable in Hong Kong, regardless of where you are resident when you exercise them. The taxable amount is the gain on exercise (market price minus exercise price), time-apportioned based on the proportion of the vesting period spent working in Hong Kong. If you leave Hong Kong and later exercise the options, you still owe Hong Kong tax on the Hong Kong-related portion.
The IRD requires employers to report stock option gains on the BIR56A/IR56B form. Employers may also be required to withhold tax on option gains. For expats with significant equity compensation, this creates a potential ongoing Hong Kong tax liability even after departure, which must be managed carefully.
Hong Kong does not impose any value-added tax, goods and services tax, or sales tax. This is a significant cost-of-living advantage compared to Singapore (9% GST), the UK (20% VAT), or most European countries (19-27% VAT). While there have been periodic discussions about introducing a consumption tax, no concrete plans exist as of 2025.
Hong Kong has comprehensive avoidance of double taxation agreements (DTAs) with over 45 countries. While smaller than the networks of the US, UK, or France, it covers most major jurisdictions relevant to expats:
| Treaty Partner | Dividend WHT | Interest WHT | Royalty WHT |
|---|---|---|---|
| United Kingdom | 0-15% | 0-15% | 0-5% |
| France | 0-15% | 0-10% | 5-10% |
| Germany | 5-10% | 0-10% | 5-10% |
| Japan | 0-10% | 0-10% | 5% |
| Mainland China | 5-15% | 7-10% | 7% |
| United States | No treaty (limited shipping/airline agreement only) | - | - |
The absence of a comprehensive DTA with the United States means US expats in Hong Kong rely solely on the FEIE and FTC under US domestic law. While this does not create double taxation for most individuals (due to Hong Kong's low rates), it means treaty-based dispute resolution mechanisms are unavailable for US-Hong Kong situations.
Hong Kong's tax year runs from April 1 to March 31. Tax returns (BIR60) are issued in early May and must be filed by early June (for individuals with sole proprietorship business) or early July (for other individuals). Tax is payable in two installments: typically 75% in January and 25% in April of the following year. The IRD offers provisional tax deferral if you can demonstrate that your current year income will be at least 10% lower than the previous year.
Most expats file their own returns, as the system is relatively straightforward compared to other jurisdictions. However, those with stock options, time-apportionment claims, or self-employment income may benefit from professional assistance.
If you leave Hong Kong permanently, you must notify the IRD in writing at least one month before departure. Your employer must also file an IR56G form and withhold all amounts due to you until the IRD issues a Letter of Release. This process ensures clearance of all tax liabilities before departure. Your MPF can be withdrawn as a lump sum upon permanent departure, subject to providing required documentation.
