There is no bonus tax in Hong Kong, only your marginal rate
People search for a bonus tax rate as if a year-end payment were taxed on its own special scale. It is not. A cash bonus is assessable income and falls into salaries tax in the year you receive it, sitting on top of your salary. The only question that matters is which band the extra money lands in. Hong Kong taxes the lower of a progressive scale and a flat standard rate, and for a normal salary the progressive scale wins. That scale charges 2, 6, 10, 14 and then 17 percent across successive $50,000 slices of net chargeable income, which are the rates this calculator applies. Because a bonus sits at the top of your income, it is usually taxed wholly at whatever band your last dollar of salary already reached.
Following a $50,000 bonus on a $600,000 salary
Consider a base salary of $600,000 with $18,000 of MPF deductions and the basic allowance of $132,000. That leaves $450,000 of net chargeable income, which is comfortably inside the 17 percent top band. Adding a $50,000 bonus simply stacks more income into that same band. Here is the comparison the tool runs, using the rates this calculator applies:
The tax rises by exactly $8,500, which is 17 percent of $50,000, because the whole bonus falls in the top band. You keep $41,500. Notice the one-off Budget reduction the tool applies, capped at $3,000, hits both the with and without figures, so it cancels out of the difference at this income and does not soften the bonus tax. The chart shows the bonus split into the $8,500 that goes to tax and the $41,500 kept.
Why MPF often takes nothing from a bonus
Mandatory MPF is 5 percent from the employee and 5 percent from the employer, but only on relevant income up to $30,000 a month, giving a hard ceiling of $1,500 each side per month, the cap this calculator and the MPFA use. Anyone on $600,000 a year is already at that ceiling every month, so a bonus paid in a month where the cap is hit attracts no extra mandatory contribution. That is genuinely different from a country with uncapped payroll tax, and it is why the take-home on a Hong Kong bonus is often higher than newcomers expect. Voluntary contributions are a separate choice and do reduce take-home if you make them.
A common mistake with provisional tax
A large bonus can inflate next year's provisional salaries tax, because the IRD assumes this year's income recurs. If the bonus was a one-off, budget for a provisional demand that looks too high, and consider an application to hold over the excess. The figures here cover the salaries tax on the bonus itself, not the cash-flow timing of provisional payments, which the IRD sets out on your assessment.
Should I ask for the bonus to be deferred to the next tax year?
Deferral only helps if your income next year will be lower, dropping the bonus into a cheaper band. For most salaried staff whose pay is stable, the band is the same in either year, so deferral changes nothing on tax. It can matter if you are leaving a job, taking a sabbatical, or expect a pay cut.
Is a bonus paid in shares taxed the same way?
A share award or vested equity is generally taxed as a perquisite under salaries tax on its value when it vests or is exercised, not as a tax-free capital gain. This calculator handles a cash bonus. For share-based pay the timing and valuation rules differ, so check the IRD guidance on share-based benefits and keep your vesting statements.
