BIR51, BIR52, BIR60, IR56B, IR56E, IR56F, IR56G, IR56M and BIR56A: who files each form, when, and where to find the detail.

The Inland Revenue Department uses a small set of forms for most business and employment reporting. This hub explains who files each one and when, and points to the detailed guides.

BIR51: profits tax return for corporations

Who files it: Hong Kong companies and other corporations. When: the return is issued in bulk at the start of the year of assessment. Represented companies may qualify for block extensions. For 2025/26, the D code deadline is 31 August 2026 and the M code deadline is 30 November 2026, subject to eligibility.

BIR52: profits tax return for partnerships

Who files it: partnership businesses. When: the same issue cycle as BIR51, with block extensions where eligible.

BIR60: individual tax return

Who files it: individuals, including sole proprietors who report business profits. For 2025/26, the return was issued on 4 May 2026. It is due on 4 June 2026 on paper or 4 July 2026 if filed electronically. Sole proprietors have until 4 August, or 4 September if filing electronically. See the BIR60 guide.

BIR56A and IR56B: the employer's return

Who files it: employers. The BIR56A is the cover return and each IR56B reports one employee's remuneration. The return is normally issued on the first working day of April and is due within one month of issue unless extended.

IR56E: new employee

File it within three months of the employee starting if the employee is likely to be liable to salaries tax.

IR56F: employee leaving

File it at least one month before the employment ends.

IR56G: employee leaving Hong Kong

File it at least one month before the employee leaves Hong Kong for good or for a substantial period. The employer must withhold payments due to the employee until the IRD issues a letter of release.

IR56M: payments to non-employees

Use this form to report commissions, fees and similar payments made to people who are not your employees, when the IRD requests it or when it applies.
