Every April officially marks the start of Hong Kong’s annual tax filing season. For companies incorporated and operating physically in Hong Kong, tax compliance is the core foundation for maintaining good corporate standing and regulatory credibility.
Many Hong Kong business owners engaged in foreign trade, cross-border e-commerce, financial investment and offshore business activities face a key statutory obligation each April — in addition to filing corporate profits tax, they must also submit the Employer’s Tax Return on time.
This filing is not only critical to corporate tax compliance but also directly determines the assessment and calculation of employees’ individual salaries tax. Incorrect declarations, omissions or delays will result in substantial penalties imposed by the Inland Revenue Department. Severe cases may even involve criminal liabilities, with company directors held legally accountable.
Complete Checklist for Hong Kong Employer Salaries Tax Filing
Hong Kong companies do not deduct tax from employees’ salaries in advance. However, employers are legally required to fully declare employees’ income details to the Inland Revenue Department — this is known as employer filing.
The IRD will cross-check income data declared by companies against individual tax returns submitted by employees. Consistent records lead to normal tax assessment and payment; mismatched information triggers official tax audits, recovery of outstanding tax and financial penalties.
Simply put, employers register employees’ income with the tax authority at the source to prevent undisclosed income and tax evasion.
I. Mandatory Employer Forms by Scenario
1. Annual General Filing (Mandatory Every Year)
BIR56A: Employer’s Return – Main Summary Form
IR56B: Remuneration Statement for Current Employees / Directors (one form per person)
Mandatory declaration items: basic salary, year-end bonuses, commissions, allowances (transport / meal / accommodation), equity and share option benefits, MPF contributions, working days in Hong Kong, and employment start & end dates.
2. Real-Time Filing for Personnel Changes
IR56E: New employee — submit within 3 months of employment commencement
IR56F: Employee resignation / death — submit within 1 month of departure
IR56G: Permanent / long-term departure from Hong Kong — submit 1 month prior to departure
IR56M: Freelancers, consultants & outsourced non-employees — file upon remuneration payment
II. Key Timelines & Deadlines
- Assessment Year: 1 April – 31 March of the following year
- Form Issuance: BIR56A and supplementary forms dispatched by the IRD in early April
- Paper Filing Deadline: Return within 1 month upon receiving official forms
- E-Filing Deadline: An additional 1-month extension allowed
- Record Retention: All payroll and employment records must be kept for 7 years
III. Mandatory Documents for Retention & Inspection

IV. Critical Compliance Reminders
- Hong Kong employers do not withhold salaries tax; only responsible for declaration, while employees file and pay tax individually.
- Nil declaration is still required even if the company has no employees throughout the year.
- Mandatory proactive filing even if official tax forms are not received.
- Late submission, omission or incorrect declaration may lead to fines and estimated tax assessment by the IRD.
Complete Guide to Filling BIR56A & IR56B
I. Core Relationship Between BIR56A and IR56B
- BIR56A: Main employer summary form — serves as the cover page and overall summary of the entire tax filing.
- IR56B: Individual remuneration statement for each employee / director.
Rule: 1 set of BIR56A + multiple IR56B forms (number matches total declarable personnel).
II. Step-by-Step Guide to Completing BIR56A
-
Verify Company Basic Information
Check company name, business registration number and registered address. Update address officially in the form if changed; the IRD will use this address for all official correspondence.
-
Core Declaration Selection
Tick YES if there are declarable employees / directors.
Tick NO if there are no employees or remuneration expenses.
Note: Nil declaration is compulsory even with zero staff; ignoring official forms is not permitted.
-
Declare Number of Supplementary Forms
- Paper filing: Fill in the number of attached IR56B forms.
- E-Filing: State the number of electronically submitted forms and attach the QR code verification sheet.
- Authorised Signature (Most Critical)
Must be hand-signed by a director, company secretary or authorised manager.
Photocopies, fax copies, scanned copies, proxy signatures and company stamps are not accepted. Only original signed documents are valid.
III. Who Must Be Declared on IR56B? Mandatory List
Any person falling into any category below must be declared, regardless of income amount:
- Company directors (regardless of income level or Hong Kong residency status)
- Employees with income exceeding the basic tax allowance (HK$132,000 for 25/26 assessment year)
- Married employees
- Part-time workers with potential additional income sources
- Overseas seconded staff
- Pension recipients (declaration required if exceeding tax allowance)
- Former employees with equity exercise gains (declaration required if exceeding tax allowance)
IV. Full Guidelines for Completing IR56B Employee Statement
-
Basic Information Section
Hong Kong ID / passport number & place of issuance, correspondence address, employment start & end dates.
Sort and number employees alphabetically by English full name.
-
Item 11: Breakdown of Income (Core Section)

-
Item 11(g): MPF & Retirement Scheme Contributions (Compliance Focus)

Proportionate Benefit = Vested Benefits × Service Months ÷ 120
-
Item 12: Residential Accommodation Benefits
Company-provided accommodation or rental subsidies must be declared here.
Mandatory records to retain: tenancy agreements, payment receipts and usage records.
Without valid supporting documents, such benefits will be reclassified as cash allowances and taxed under Item 11(k).

Item 13: Remuneration Paid by Non-Hong Kong Entities
Salaries paid by overseas parent companies must be fully declared.
Convert foreign currency to Hong Kong Dollars using the IRD’s official average exchange rate (no cents rounding).
