Calculating payroll tax withholding in Hong Kong primarily revolves around understanding the territory’s Salaries Tax system, as Hong Kong does not have a traditional payroll tax like some other jurisdictions. Instead, individuals are taxed under the Salaries Tax on their income arising in or derived from employment in Hong Kong. Employers do not withhold tax directly from an employee’s salary for Salaries Tax purposes. However, they play a crucial role in the process through reporting and sometimes making payments on behalf of employees under certain circumstances.

Key Points on Salaries Tax:

  • Taxation Method: Unlike many countries that deduct taxes monthly from employee wages, Hong Kong utilizes an annual assessment approach for Salaries Tax.
  • Tax Rates: For the 2022/23 assessment year, progressive tax rates range from 2% to 17%, with an alternative standard rate of 15% on net income, depending on which calculation results in lower tax payable.
  • Calculation Process:
    • Determine Taxable Income: Sum up all income from employment and subtract any applicable allowances and approved donations.
    • Compute Net Chargeable Income: Deduct allowances from the total taxable income.
    • Apply Tax Rates: The tax due is calculated using either the progressive rates on the net chargeable income or the standard rate on net income, opting for the lower of the two.

Employer Responsibilities:

Employers in Hong Kong have a crucial role in facilitating the Salaries Tax process, albeit not through direct withholding. Their obligations include:

  • Annual Reporting: Employers must submit an annual return (BIR56A and IR56B forms) to the IRD, detailing the remuneration paid to employees.
  • Inform and Assist Employees: While not directly withholding taxes, employers are expected to inform employees about their potential Salaries Tax liabilities and assist in understanding the calculation process.

Provisional Tax:

The IRD may issue provisional tax bills based on the previous year’s earnings, which act as advance payments towards the current year’s tax liability. Any overpayment is later refunded or offset against the final tax payable.
