Note: This article was published in April 2018 and has been updated in April 2024 to reflect the latest updates to the Hong Kong Tax Filing/Submission process. As of April 2024, Talenox supports five IR56 forms: IR56B, IR56E, IR56F, IR56G, and IR56M.

Hong Kong is a popular investment centre because of its world-class infrastructure and connectivity. That’s why entrepreneurs all over the world look to Hong Kong as one of their expansion cities. Many even consider it a suitable hub to house regional and/or global headquarters. If you currently operate a business and employ people in Hong Kong, you must be aware of Hong Kong’s taxation system and your employer obligations.

What is the employer’s tax obligation in Hong Kong and how does IR56 apply?

IR56 refers to a series of forms used by employers in Hong Kong to report the salaries and wages of their employees to the Inland Revenue Department (IRD). These forms are part of the employer’s annual obligations and are critical for the accurate assessment of individual income taxes.

In general, the tax year runs from 1 April to 31 March. Hence, employers usually start preparing their tax forms on 1 April

In Hong Kong, there is no income tax withholding throughout the tax year. As an employer, you will need to report remuneration (i.e. salaries/wages) paid to employees by submitting an Employer’s Return. After all, it is the company’s responsibility to declare, file and pay each employee’s annual income taxes via the Inland Revenue Department (IRD).

This is done annually, or, once a year – with forms BIR56A and IR56B. Depending on each employee’s circumstance, you may have to file the other forms instead, i.e. IR56E, IR56F, IR56G or IR56M.

If you’re unsure where to start, don’t worry – we’re here to give you a primer on each IR56 form’s application purpose.

IR-what? The different tax forms

There are five IR56 forms you must be familiar with. 


As an employer, you must submit IR56B for your employees yearly for the Inland Revenue Department (IRD) to calculate the tax contribution. This is the most commonly used form, which employers must complete annually for each employee. It details the employee’s total income over the financial year, including salaries, bonuses, and allowances. If you have 10 employees, you will submit 10 IR56B forms. If you have 100 employees, you will submit 100 IR56B forms.

This is done every year in April, from 1st April to 30th April. The taxes will pertain to the salary earned from 1st April of the previous year to 31st March of the current year. Example: When you file IR56B in April 2024, you are filling based on payroll records from 1st April 2023 to 31st March 2024. 

IRD will send the form, BIR56A, by mail to the employer on the working day every year. You will then need to complete BIR56A and IR56B; and then return them to IRD within one month after you received BIR56A.

Remarks on BIR56A:

The BIR56A form in Hong Kong serves as a cover letter accompanying the submission of IR56B forms, which detail the remuneration paid to employees during the fiscal year. Here’s a detailed look at the BIR56A form, its purpose, and how it is used in the context of payroll and tax reporting in Hong Kong:

  • Employer Information: The BIR56A form includes sections where the employer must fill in their company’s details, including the business registration number, name, and address. This identifies the employer to the IRD and links the submitted IR56B forms to the correct entity.
  • Employee Count: This form requires employers to declare the total number of IR56B forms being submitted. This helps the IRD ensure that all forms are accounted for and that the employer has complied with the requirements for all employees.
  • Declaration: The form includes a declaration that the information being submitted is correct. The employer, or a person authorized by the employer, must sign the BIR56A form, verifying the accuracy of the information on both the BIR56A and the attached IR56B forms.
  • Submission: The completed BIR56A form, along with all IR56B forms, must be submitted to the IRD by the specified deadline, which is typically April 1st. Late submissions can result in penalties and interest charges.


This form is used when an employee commences employment. It provides the IRD with initial salary details and other compensation information. You’ll only need to submit IR56E for new hires charged under the Salaries Tax. The submission has to be done within 3 months from the commencement of employment or date of hire.


You might wonder whether you need to file IR56E for freelancers or contracted staff under your employment. The answer is, no. The reason is that freelancers and contracted staff are considered ‘non-employees’ who are charged under Salaries Tax. That is why IRD has a separate form – IR56M – to track data on non-employee paid individuals like:

  • Consultants, agents, brokers, freelance artistes, entertainers, sportsmen, writers, freelance guides, etc. to whom commission, fees or other remuneration paid exceeded a total of $25,000 per annum for the relevant year ended 31 March.
  • Sub-contractors to whom fees or other remuneration paid exceeded a total of $200,000 per annum for the relevant year ended 31 March.


This form pertains to employees who are about to leave the company (e.g. cessation of employment, resignation, or termination). As an employer, you will need to submit this form one month prior to the actual departure date.

IRD specifically designed this form for leavers who will remain in Hong Kong; it is different from the one below (i.e. IR56G) is for those who are leaving Hong Kong.

For resignees, you will need to submit this 1 month prior to the cessation of employment or resign date.


Similar to IR56F, this form pertains to employees who are about to leave the company. The difference is that Form IR56G is designed for leavers who are leaving Hong Kong for an extended period of time, while Form IR56F is for leavers remaining in the country.

So, if your employee is a foreigner (or not) and he/she is leaving Hong Kong after the cessation of employment, you will need to submit this form one month before the expected departure date of this employee.

Any employer who files Form IR56G will also need to withhold all further payments to the employee from the date of filing IR56G. The employer will then need to provide a copy of IR56G to the leaving employee; that’s because the employee will need a copy of IR56G to show IRD proof of tax clearance. 

Leaving employee will only receive a “Letter of Release” once he/she fully settles all remaining tax responsibilities before departing the country. 

Once the “Letter of Release” is granted, the employer may request for it and then make the final payment (previously withheld) to this leaving employee.
