Tax Identity for the Self-Employed: Profits Tax vs. Salaries Tax

Many newly self-employed individuals are often confused about which tax they are required to pay. Unlike employed individuals who pay Salaries Tax, self-employed persons and sole proprietors are subject to Profits Tax. The Hong Kong Inland Revenue Department does not have a standalone "self-employment tax" category; if you operate as a sole proprietorship or partnership, you must report Profits Tax on assessable profits through the Individual Tax Return (BIR60).

Two-Tiered Profits Tax Rates Regime: Benefits for the Self-Employed

Hong Kong's two-tiered profits tax rates regime, introduced to support SMEs (including self-employed individuals and sole proprietors), is particularly advantageous for startups and small-scale businesses.

Business Type First HK$2 Million of Profits Profits Above HK$2 Million
Unincorporated businesses (Sole proprietors / Self-employed persons) 7.5% 15%
Corporations (Limited companies) 8.25% 16.5%
💡 Pro Tip: Only one entity among connected entities is eligible to elect for the lower rate on the first HK$2,000,000 of profits. If you own multiple businesses, you need to strategically select which one applies for the preferential tax rate.

Example: If you are a freelance web developer with an annual assessable profit of HK$500,000, you will only need to pay HK$37,500 in profits tax (HK$500,000 x 7.5%). This is one of the most competitive tax regimes in the world for independent professionals.

Business Registration: The First Step to Operating Legally

Before operating legally as a self-employed individual or sole proprietor in Hong Kong, you must obtain a Business Registration Certificate. This is a fundamental requirement often overlooked by beginners, which may result in penalties.

⚠️ Important Notice: You must apply for business registration within 1 month of commencing business operations. The Inland Revenue Department strictly enforces this deadline, and late registration may incur fines.

How to Register a Sole Proprietorship Business

  1. Prepare the required information:
    • Proposed business name (must not duplicate existing registered names)
    • Nature of business (detailed description of your services)
    • Business address (home-based self-employed individuals may use a residential address)
    • Hong Kong Identity Card (for residents) or passport (for non-residents)
    • Contact details (phone number and email address)
  2. Submit the application: Complete the online form via "eTAX" or submit Form IRBR1 in person at the Business Registration Office.
  3. Pay the registration fee: Fees for the period from April 2024 to March 2025:
    • 1-year certificate: HK$2,200
    • 3-year certificate: HK$6,020 (average of approx. HK$2,007 per year, saving approx. HK$193 annually)
  4. Collect the certificate: Upon successful application, the Business Registration Certificate will be issued immediately.

Leveraging "eTAX": Your Digital Tax Partner

"eTAX" is the official online tax filing and management platform of the Inland Revenue Department. For self-employed individuals, it offers multiple advantages over traditional paper-based filing: an automatic one-month extension, 24/7 availability, instant acknowledgment receipts, secure document storage, real-time updates on assessment and refund status, and an eco-friendly, paperless experience.

Understanding Your Tax Return: BIR60 for Sole Proprietors

As a self-employed person operating as a sole proprietor, you will receive a Tax Return - Individuals (BIR60). This composite tax return covers multiple sources of income, with Part 5: Details of Sole Proprietorship Business and Profits / Losses being crucial for self-employed individuals. In this section, you need to report your business name and registration number, nature of business, accounting period, gross income, total deductible expenses, and net profit or loss.

Key Deadlines and Tax Filing Schedule

First Notification to the Inland Revenue Department

Many beginners mistakenly assume that the Inland Revenue Department (IRD) will automatically be aware of their business commencement. This is incorrect. You must notify the IRD in writing within 4 months after the end of the basis period for the year of assessment in which you commenced business.

Example: If you commenced your self-employed business on 1 May 2024 and your accounting year ends on 31 March 2025, you must notify the IRD by 31 July 2025 (i.e., within 4 months after 31 March).

Annual Tax Filing Deadlines

Tax Type Issue Date Paper Submission Deadline "eTAX" Submission Deadline
Individuals (BIR60) First working day of May each year (e.g., 2 May 2024 for the 2024/25 year of assessment) Within 1 month from the date of issue (usually early June) Automatic 1-month extension (usually early July)
Profits Tax (if applicable) Depends on the accounting year-end date Within 1 month from the date of issue Automatic 1-month extension
💡 Pro Tip: Always file your tax return via "eTAX" to enjoy the benefit of an automatic one-month extension. This extra time is essential for organizing financial documents and ensuring accuracy.

Maximizing Deductible Expenses: What You Can Claim

The Golden Rule: Wholly and Exclusively in the Production of Assessable Profits

The IRD applies a straightforward yet strict criterion for expense deductions: expenses are deductible only if they are wholly and exclusively incurred in the production of assessable profits and are not of a capital nature.

  • "Wholly" means the entire sum must be used for the business. If an expense serves both business and private purposes (such as a mobile phone), you must apportion it and claim only the business portion.
  • "Exclusively" means the expense must be incurred solely for the purpose of generating business income, not for personal or capital purposes.
  • "Not capital in nature" means the expense must be for day-to-day operations rather than the acquisition of long-term assets (although qualifying assets may be eligible for specific depreciation allowances).

Common Deductible Expenses for Self-Employed Persons

Expense Category Examples Points to Note
Office Expenses Rent, utilities, stationery, office supplies Home office expenses require a dedicated workspace and careful apportionment
Professional Services Accounting fees, legal fees, consultancy fees Must be related to business operations
Marketing & Promotion Web hosting, online advertising, business cards, promotional materials Fully deductible if incurred solely for promoting the business
MPF Contributions Mandatory contributions for self-employed persons Annual cap of HK$18,000, fully tax-deductible
Approved Charitable Donations Donations to approved charitable institutions Minimum HK$100, capped at 35% of assessable profits

MPF Obligations for Self-Employed Persons

Hong Kong's Mandatory Provident Fund (MPF) system covers self-employed persons. This retirement savings scheme is not voluntary, but a legal requirement with specific contribution obligations and benefits.

Contribution Calculation

Self-employed persons must make MPF contributions at 5% of their relevant income, subject to minimum and maximum relevant income levels:

Income Level Monthly Relevant Income Annual Relevant Income Required Contribution
Below minimum level Less than HK$7,100 Less than HK$85,200 Not required to contribute
Between minimum and maximum levels HK$7,100 to HK$30,000 HK$85,200 to HK$360,000 5% of relevant income
Above maximum level More than HK$30,000 More than HK$360,000 Capped at HK$1,500 per month (HK$18,000 per year)
💡 Pro Tip: MPF mandatory contributions for self-employed persons are fully tax-deductible, up to an annual limit of HK$18,000. This deduction reduces your assessable profits, effectively providing tax relief for your retirement savings.

Back to top

Hong Kong laws require all businesses (including sole proprietorships and self-employed persons) to retain complete and accurate business records for at least 7 years. This obligation continues even after the cessation of business.

Financial Statement Requirements

Annual Gross Income Level Required Documents
HK$2,000,000 or below No need to submit financial statements (but records must still be retained, and a summary must be provided in BIR60)
More than HK$2,000,000 Must submit a certified balance sheet, profit and loss account, and tax computation

Personal Assessment: A Tax-Saving Strategy

Many self-employed individuals have multiple sources of income, such as part-time employment income, self-employed business profits, and even rental income from properties. In such cases, electing for Personal Assessment may help reduce your overall tax burden.

How Personal Assessment Works

Under normal circumstances, employment income is subject to Salaries Tax (progressive rates of 2% to 17%, or standard rates of 15% on the first HK$5,000,000 and 16% thereafter); business profits are subject to Profits Tax (two-tiered system of 7.5%/15%); and rental income is subject to Property Tax (15% of net assessable value).

By electing for Personal Assessment, you can:

  • Aggregate all sources of income into a single total income
  • Deduct all applicable personal allowances (Married Person's Allowance, Child Allowance, Dependent Parent Allowance, etc.)
  • Calculate tax on the net total income at the progressive Salaries Tax rates (2% - 17%), rather than paying the single flat rates for Profits Tax or Property Tax
💡 Pro Tip: You can elect for Personal Assessment by ticking the relevant box when completing your Tax Return - Individuals (BIR60). The Inland Revenue Department will automatically compute which method is more advantageous for you and apply the one resulting in the lower tax liability.
