Part-Time & Casual Work Tax Specialist

Salaries Tax When You Work Part-Time or for Several Employers

The complication with part-time and casual work is not the rate — it is that each employer reports you separately while the IRD assesses you once on the combined total, and MPF for casual staff has its own rules. That is where the surprises come from.

⚠️

⚠ Part-Time Employers: IR56M Filing Is Mandatory

Employers paying casual or part-time workers more than HKD 2,000 per month must file IR56M returns with the IRD by 1 April each year. Failure to file is a criminal offence under s.52 of the IRO. Many small businesses and household employers are unaware of this obligation.

常見困擾

您是否正面對以下稅務問題？

Allowance Claiming When Income is Low

Part-time workers often earn below the basic allowance threshold and owe no tax — but must still file a return if required by IRD. Correctly claiming allowances ensures no overpayment.

⚠ Risk: Not filing when required → automatic penalty

MPF Obligations for Low Earners

Part-time workers earning less than HKD 7,100/month are exempt from mandatory MPF contributions — but the threshold applies monthly, not annually.

⚠ Risk: Employer making unnecessary deductions → employee complaint

Multiple Employer Reporting

Workers with two or more part-time jobs must consolidate all income for salaries tax purposes — each employer only sees their portion.

⚠ Risk: Under-declaring combined income → underpaid tax + interest

Employer IR56M vs IR56B

Casual workers (irregular, no formal contract) are reported on IR56M; regular part-timers under a contract are reported on IR56B. Using the wrong form creates IRD enquiries.

⚠ Risk: Wrong form → IRD rejection and re-filing penalty

常見問題

常見問題

快速解答您的疑問

At HKD 96,000/year, your income is below the basic personal allowance of HKD 132,000 for 2025/26, so no salaries tax is payable. However, if the IRD sends you a BIR60 return, you must file it (you simply declare your income and claim your allowance). You can also submit a "no tax payable" return proactively.

No. Salaries tax is assessed on your total income from all sources. Each employer reports their portion to the IRD, and the IRD consolidates this into a single assessment in your name. You pay tax once on the combined amount, after deducting your personal allowances.

No. Unlike many countries, HK does not operate a PAYE (pay-as-you-earn) withholding system. Your employer does not deduct tax from your wages. Instead, you pay your salaries tax in two annual instalments (January and April) based on the IRD's assessment, which includes a provisional tax element.

Yes. If you regularly employ a tutor (as opposed to occasional one-off payments), you may have employer reporting obligations under IR56M. You should also consider whether MPF applies — if the tutoring engagement is more than 60 days, MPF contributions are generally required.

Yes. Mandatory MPF contributions made as an employee (5% up to HKD 1,500/month) are fully deductible from your assessable income. Even at part-time income levels, this deduction reduces your tax liability.
