If you are an employer in Hong Kong, it is essential to understand the differences of IR56A vs IR56B clearly to operate your business lawfully. These forms issued by the Inland Revenue Department (IRD) are important in reporting employees’ remuneration and ensuring compliance with local tax laws.
Most employers, especially SMEs and Startups, mix the intentions and timelines of IR56A and IR56B. This may lead to penalties, stress, and delays in tax compliance.
Here, we’ll summarize the main differences between IR56A and IR56B, with some knowledge about IR56F for cessation of an employee. By the time you’re finished reading, you’ll understand when and how to file — and how FastLane HR’s tax professional services can help you maintain compliance with ease.
What is IR56A?
IR56A is the employer’s annual return form. It’s a summary form that informs the IRD that your company is submitting employee remuneration details for the year of assessment.
Key points regarding IR56A:
Purpose: To be used as a cover sheet in submitting employee IR56B forms.
Who files: All employers in Hong Kong, including corporations, SMEs, and startups, have to file IR56A if they have employees.
When to file: By the end of April following the close of the tax year (1 April to 31 March).
Contained: IR56B forms, number of employees, and employer’s signature.
IR56A is the summary page that certifies all breakdown employee income forms (IR56B).
What are the requirements of IR56?
The IR56 series encompasses several forms that employers in Hong Kong might need to file. There is a different form for each situation:
IR56A – Employer’s annual return (summary).
IR56B – Employee’s annual remuneration return.
IR56E – For a new employee commencing employment.
IR56F – For a departing employee.
IR56G – for an employee leaving Hong Kong.
Employer responsibilities for IR56 forms:
- Maintain an accurate and up-to-date payroll record.
- Report all remuneration details including salary, allowances, pension and benefits.
- Enter the appropriate form on time to prevent punishment.
- Ensure that the income details of the employees matches the payroll record of the company.
- Non-compliance may attract IRD penalties, investigation, and reputational damage.
What is the IR56B form in Hong Kong?
IR56B is used to report detailed remuneration for every employee, whereas IR56A is a summary.
IR56B main marks:
Objective: Reporting the income and benefits of an individual employee for the year of evaluation.
Who files it: for the employer, for each employee (including directors, full -time and part -time employees, and migrants).
Necessary details:
- Salary, wages, bonus, commission
- Housing benefits
- Employer’s contribution to retirement schemes
- Share options, allowances and taxable benefits
When to file: By the end of April, together with IR56A.
IR56A is incomplete without IR56B. Both forms are to be submitted together for reporting purposes.
When to submit IR56F?
While IR56A and IR56B deal with annual reporting, IR56F is required when an employee ceases employment in Hong Kong.
IR56F key points:
Purpose: To notify the IRD that an employee has left the company.
Deadline: Must be filed within 1 month of the employee’s cessation date.
Usage:
- Employee resigns
- Contract ends and is not renewed
- cessation of employment (except where death occurs or the employee departs Hong Kong — that needs IR56G).
IR56F reports the final salary and tax obligations of the submitting employee correctly.
