2026 Hong Kong tax season must‑read! Whether you are a limited company, an unlimited company, or a self‑employed individual, even if you have “zero operations” or are making a “loss”, you are still required to file taxes on time. This article provides you with illustrated guidance on the latest tax filing procedures, two‑tiered tax rate calculations, and the latest 2026 tax deductions, helping you stay compliant, save tax legally, and avoid heavy penalties for late filing.

I. Basic Knowledge of Hong Kong Company Tax Filing

Hong Kong, as an international financial hub, has a simple and competitive tax system. Understanding the statutory tax filing obligations is key to a company’s financial health.

Statutory obligation: All registered limited companies, regardless of whether they have income, must file a Profits Tax Return. Dormant companies may be exempted from submitting an audit report, but they are still required to file a return with all zero figures.

Types of Tax Returns:

• Limited companies: BIR51 form
• Unlimited companies/partnership businesses: BIR52 form
• Non‑Hong Kong resident related persons: BIR54 form

II. 2026 Corporate Tax Filing Process and Timeline

Company Type / Stage	Time of Receiving Tax Return	Submission Deadline & Notes
Newly Incorporated Limited Company	Within 18 months from the date of incorporation	The deadline for the first tax return submission is 3 months.
Established Limited Company	Early April every year	Usually submitted within 1 month (extension can be applied for through a tax representative).
Unlimited Company and Partnership	Early April every year	Must be submitted within 1 month.
Audit Requirement (Turnover ≤ 2 Million)	–	An audit is still required, but the audit report does not need to be attached when filing the tax return; only the auditor’s name and date need to be filled in.
Audit Requirement (Turnover > 2 Million)	–	Must be submitted together with the signed audit report and profits tax computation sheet.

(Note: If a tax return is submitted late without authorization, there is a chance of being fined HK$10,000 and an additional tax of up to 3 times the amount of the relevant tax.)

IV. List of Deductible Expenses

Under Section 16 of the Inland Revenue Ordinance, the following common operating expenses are deductible:

• Cost of goods purchased

What is a self‑employed person?
An individual who works independently without an employment relationship and earns income (e.g., designers, consultants). Self‑employed persons do not sign standard employment contracts with clients, have no mandatory MPF contribution requirements, and must arrange their own employee benefits.

Benefits of obtaining a Business Registration (BR):

• Avoid penalties: Late registration may result in a fine of HK$5,000 and imprisonment for up to 1 year.

• Government funding opportunities: Eligibility to apply for government SME funding schemes.
• Bank account safety: Avoid bank account freezes caused by using personal accounts to receive business payments.

Conditions for exemption from Business Registration fee:

• Service‑type businesses: Average monthly turnover less than HK$10,000.
• Other businesses: Average monthly turnover not exceeding HK$30,000 (calculated over the first 6 months).
  Note: Exemption applies only to unlimited companies (sole proprietorship or partnership). Application must be submitted on Form IRBR61C one month before the certificate expires.
