How Does Hong Kong Calculate Your Tax?

Hong Kong has a unique "pay the lower" system. The IRD calculates your tax using two completely different methods, then charges you whichever amount is lower. This ensures you always pay the minimum tax legally required.

Method 1: Progressive Rates (2% to 17%)

This method applies graduated tax rates to your income after BOTH deductions AND allowances:

• First HKD 50,000: 2% = HKD 1,000
• Next HKD 50,000: 6% = HKD 3,000
• Next HKD 50,000: 10% = HKD 5,000
• Next HKD 50,000: 14% = HKD 7,000
• Remainder: 17%

Method 2: Standard Rates (15% / 16%)

This method applies flat rates to your income after deductions but BEFORE allowances:

• First HKD 5 million: 15%
• Amount over HKD 5 million: 16%

Example Comparison

Scenario: Single person earning HKD 500,000

Progressive: HKD 500,000 - HKD 132,000 allowance = HKD 368,000 taxable. Tax = ~HKD 53,000

Standard: HKD 500,000 × 15% = HKD 75,000 (no allowance deduction)

Result: Progressive method is lower, so you pay HKD 53,000 (minus HKD 3,000 rebate)

Key Takeaways

• You don't choose - the IRD automatically applies the lower amount
• Generally, progressive rates benefit most taxpayers under ~HKD 2-3 million annual income
• Having more dependents makes progressive rates even more favorable
• Very high earners often benefit from standard rates despite losing allowances
