Why the progressive rate applies here
Hong Kong works out your tax two ways and charges you whichever is lower. The progressive method applies 2%-17% bands to your income after the HK$132,000 basic allowance and MPF deduction, giving HK$60,370. The standard rate method applies a flat 15% (16% above HK$5m) to your income after MPF but with no allowance, giving HK$90,900. At this salary, the progressive calculation is lower, so that's what you pay: HK$60,370.

Calculations use 2025/26 year of assessment IRD Salaries Tax rates and MPFA contribution limits, and assume a single filer with no dependents claiming only the basic allowance. Married persons, parents, and those with dependents qualify for materially higher allowances (e.g. HK$264,000 married allowance, HK$130,000 per child) not modeled here, so this understates take-home for those taxpayers. Does not include any one-off Budget tax rebates that may apply in a given year. For precise figures consult a tax professional or the Inland Revenue Department.
