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$145,000 basic allowance and MPF deduction, giving HK$86,890. The standard rate method applies a flat 15% (16% above HK$5m) to your income after MPF but with no allowance, giving HK$114,300. At this salary, the progressive calculation is lower, so that's what you pay: HK$86,890.

Calculations use 2026/27 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$290,000 married allowance, HK$140,000 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.
Permanent median

HK$675,110 take-home
Contract median
HK$4,728/day
≈ HK$1,040,160 gross a year
At a median HK$4,728/day, contract work grosses about HK$1,040,160 a year over 220 billable days, 33% more than the HK$780,000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See Web3 Security Engineer contract rates and contractor take-home →
