One of Hong Kong's biggest financial advantages is its income tax system. Salaries Tax is simple, low, and contains few surprises — a stark contrast to the complexity of tax systems in the UK, US, or Australia. Understanding it fully ensures you claim every allowance you're entitled to.

How HK Salaries Tax Works

HK taxes income on a territorial basis — only income derived from or arising in Hong Kong is subject to Salaries Tax. Foreign-sourced income is generally not taxable in HK, making it particularly attractive for internationally mobile professionals.

Tax is assessed annually by the Inland Revenue Department (IRD) based on your tax return. The year of assessment runs from 1 April to 31 March.

Tax Rates

There are two ways your tax is calculated — you pay whichever is lower:

Progressive Rate

  • First HKD 50,000 of net chargeable income: 2%
  • Next HKD 50,000: 6%
  • Next HKD 50,000: 10%
  • Next HKD 50,000: 14%
  • Remainder: 17%

Standard Rate

A flat 15% on net total income (assessable income less allowable deductions, before personal allowances). This is the effective cap — even very high earners pay no more than 15% of gross income.

15%

The maximum effective Salaries Tax rate in Hong Kong — among the lowest for a major financial centre globally. A comparable earner in the UK would pay up to 45%; in the US, up to 37% federal plus state taxes.

Personal Allowances

Before calculating your tax, you deduct personal allowances from your assessable income. These reduce your tax bill significantly:

  • Basic Allowance: HKD 132,000 per person
  • Married Person's Allowance: HKD 264,000
  • Child Allowance: HKD 130,000 per child (1st–9th child; additional for disabled child)
  • Dependent Parent/Grandparent Allowance: HKD 25,000–50,000 per parent/grandparent depending on age and co-habitation
  • Single Parent Allowance: HKD 132,000
  • Disabled Dependent Allowance: HKD 75,000 per disabled dependent

Allowable Deductions

You can also deduct certain expenses from assessable income before applying allowances:

  • MPF contributions: Up to HKD 18,000 per year
  • Self-education expenses: Up to HKD 100,000 per year for courses relevant to your work
  • Home loan interest: Up to HKD 100,000 per year for up to 20 years of assessment
  • Elderly residential care expenses: Up to HKD 100,000 per year
  • Approved charitable donations: 100% deductible (minimum HKD 100)

When Do You File?

The IRD sends out tax returns each May for the preceding year of assessment. You typically have one month to file (extended to three months if you use a tax representative). Late filing can result in penalties. Most employees' tax is relatively straightforward — the IRD also offers a simplified return for those with straightforward employment income.

Provisional Tax

HK uses a system of Provisional Tax — you pay an estimate of next year's tax alongside this year's final assessment. This can create large lump-sum payments in January/February (when demand notes typically arrive). Budget for this; it catches many people off guard in their first year in HK.

Tips to Legally Reduce Your HK Tax Bill

  • Maximise MPF contributions (tax-deductible up to HKD 18,000)
  • Claim all eligible allowances — many people miss dependent parent/grandparent allowances
  • Consider a Qualifying Deferred Annuity Policy (QDAP) — premiums are tax-deductible up to HKD 60,000 per year
  • Charitable donations to approved institutions are fully deductible
  • If your employment has periods outside HK, apportion your income correctly — you may only owe HK tax on the HK portion
