Filing self-employment tax as a freelancer has never been this easy

You made the leap. You’re your own boss now, chasing a dream and building something from scratch. It’s an amazing feeling, but then you hear those three little words that can cause a big headache: self-employment tax. It sounds scary, like some extra penalty for having the guts to work for yourself.

But it’s not. It’s just a different way of handling taxes you would have paid anyway as an employee. You’ll learn all about how to handle the self-employment tax without the stress and confusion.

Who qualifies as a self-employed person?

In Hong Kong, you are considered self-employed if you carry on a trade, profession, or business on your own account, rather than being employed by someone else. You are essentially your own boss.

The key distinction lies in the type of contract you have for your work. A self-employed person operates under a “contract for services,” meaning you are hired to provide a specific service or complete a project. An employee, on the other hand, works under a “contract of service.”

You likely qualify as self-employed if you are:

A freelancer (e.g., writer, designer, programmer)
An independent contractor
A sole proprietor running your own business (e.g., a shop owner, consultant)
A partner in a partnership business
A tutor, entertainer, or gig worker who is not on a company’s payroll

The Inland Revenue Department (IRD) looks at the whole picture of your work arrangement to determine your status. They consider factors like

Control (who decides how, when, and where the work is done),
Ownership of tools, and
Financial risk (do you bear the risk of making a profit or loss?)

If you control these factors, you are likely self-employed.

What is self-employment tax?

There is NO separate “self-employment tax” in Hong Kong. Instead, if you’re self-employed, a freelancer, rental owner, or a startup founder operating as a sole proprietor or in partnership, you need to either pay salaries tax or file profits tax return, or even both.

This tax is charged on the assessable profits your business earns from carrying on a trade, profession, or business in Hong Kong.

Do you need to file self-employment tax in Hong Kong?

You need to file for your self-employment income in Hong Kong if you carry on any trade, profession, or business in the city. The key obligation is to report these business activities to the Inland Revenue Department (IRD).

There are two main situations that determine your need to file.

1. You received a profits tax return

If the Inland Revenue Department (IRD) sends you a Profits Tax Return (Form BIR52 for individuals), you are legally required to complete and submit it by the given deadline.

This applies even if:

Your business did not make any profit.
Your business was inactive during the tax year.

You cannot ignore the form. Failure to submit it on time can lead to penalties.

2. You haven’t received a tax return (but should have)

If you are running a business or are self-employed and earning income in Hong Kong but have not received a profits tax return, you still have a legal duty to act.

You must inform the IRD in writing that you are liable to pay profits tax.

Who this applies to: Any freelancer, sole proprietor, or partner in a business who has started earning self-employment income.
Deadline to notify the IRD: You must do this within 4 months after the end of the basis period for the year you started your business.

In short, if you’re your own boss in Hong Kong, you need to be proactive about your tax obligations, whether the IRD contacts you first or not.

Hong Kong Taxation: A Complete Guide to Profits & Salaries Tax

Profits tax or salaries tax: Which one should you file as a freelancer?

Do you report profits tax or salaries tax as a freelancer or self-employed person in Hong Kong? The answer depends entirely on the source of your income.

The key is to identify whether you are earning money as an employee or as a business owner.

If your income comes from a traditional job where you are an employee, you need to report Salaries Tax.

If your income comes from your own personal business, trade, or profession, you need to report Profits Tax.

It is common to earn income from both a regular job and your own freelance work. For instance, you might have a part-time salaried job while taking on your own projects.

If you do, you must report both. This means you will file for Salaries Tax on your employment income and file a separate Profits Tax Return for your business income.

4 steps to calculate your self-employed tax

When you have both a salary and self-employment income in Hong Kong, you don’t simply add two tax bills together. Instead, you can elect for personal assessment to potentially lower your overall tax.

What is personal assessment?

Personal assessment is a tax-saving option in Hong Kong that lets you combine all your personal income sources into a single calculation.

Essentially, you are asking the Inland Revenue Department (IRD) to add up all your money, such as your salary from a job, profits from your freelance business, and any rental income into one total sum.

From this combined total, you can subtract your personal allowances (like the basic allowance). The remaining income is then taxed at progressive rates, which often results in a lower tax bill than paying tax on each income source separately.

Step 1: Calculate each income stream separately

First, you need to determine the profit or loss for each income source as you would normally:

For your job: Calculate your Net Assessable Income under Salaries Tax (your total salary minus any allowable expenses).
For your business: Calculate your Assessable Profits under Profits Tax (your business income minus all allowable business expenses).

Step 2: Elect for personal assessment

This is the most important step. On your Tax Return – Individuals (Form BIR60), you can choose (elect) to be assessed under personal assessment. This option tells the Inland Revenue Department (IRD) to combine all your income sources to be taxed together.

Step 3: Combine income and deduct allowances

The IRD will calculate your total assessable income by adding your employment income and business profits together. From this combined total, you can then deduct your personal allowances for the Year of Assessment 2024/2025, such as:

Allowance Type	Amount (HKD)
Basic Allowance	$132,000
Married Person’s Allowance	$264,000
Child Allowance	$130,000 (per child)
Additional Child Allowance (in year of birth)	$130,000
Dependent Parent/Grandparent (Age 60+)	$50,000 (per person)
Dependent Parent/Grandparent (Age 55-59)	$25,000 (per person)
Dependent Brother/Sister Allowance	$37,500 (per person)
Single Parent Allowance	$132,000
Personal Disability Allowance	$75,000
Disabled Dependant Allowance	$75,000 (per person)

This is a major benefit, as your personal allowances can now offset both your salary and business profits.

Step 4: Apply progressive tax rates to the final amount

After deducting your allowances, the remaining income is your net chargeable income. This final amount is then taxed using the progressive salaries tax rates (which start at 2% and go up to 17%), not the flat 15% standard profits tax rate.

The IRD will automatically determine if personal assessment results in a lower tax bill for you. Electing for it is almost always beneficial if you have both profits and are eligible for personal allowances.

Here’s an example showing how personal assessment can save you money.

Let’s imagine a freelance designer named Alex.

Business Profit: Alex’s freelance business made an assessable profit of HK$400,000 this year.
Personal Situation: Alex is single and has no other income. Alex is entitled to the Basic Allowance of HK$132,000.

Here are two ways Alex’s tax could be calculated.

Scenario 1: Paying profits tax separately

If Alex pays Profits Tax directly on the business earnings, the personal Basic Allowance cannot be used.

Assessable Profits: HK$400,000
Tax Rate (first tier): 7.5%
Calculation: HK400,000 x 7.5%$
Total Tax Owed: HK$30,000

Scenario 2: Electing for personal assessment

By choosing Personal Assessment, Alex can use the Basic Allowance to lower the taxable income.

Total Income: HK$400,000 (from the business)
Deduct Allowances: HK400,000 – HK132,000(BasicAllowance)=∗∗HK268,000** (This is the Net Chargeable Income)
Apply Progressive Rates: This HK$268,000 is taxed in brackets:
- First HK50,000 at 21,000
- Next HK50,000 at 63,000
- Next HK50,000 at 105,000
- Next HK50,000 at 147,000
- Remaining HK68,000 at 1711,560

Total Tax Owed: HK$27,560

The result savings

Tax without Personal Assessment: HK$30,000
Tax with Personal Assessment: HK$27,560

By electing for Personal Assessment, Alex saves HK$2,440 in tax. The savings can be even greater if you have more allowances (like for children or dependent parents) or multiple sources of income.

5 Common mistakes to avoid when filing for self-employment tax in Hong Kong

When filing for what’s known as “self-employment tax” (officially Profits Tax) in Hong Kong, avoiding simple errors can save you time and money. Here are the most common mistakes freelancers and professionals make.

1. Mixing personal and business expenses

A frequent mistake is claiming deductions for personal expenses. You can only deduct expenses that were wholly and exclusively for producing your income.

For example, a client lunch is a business expense, but your daily personal coffee is not. Keep separate bank accounts for business and personal finances to make this easier.

2. Poor or incomplete record-keeping

The law requires you to keep all business records, including invoices, receipts, and bank statements, for at least 7 years.

Without proper records, you can’t prove your expense claims if the Inland Revenue Department (IRD) asks. If you can’t provide proof, the IRD can disallow your deductions, resulting in a higher tax bill.

3. Forgetting to claim all allowable deductions

Many self-employed individuals miss out on valid deductions, paying more tax than necessary. It is crucial to be thorough and claim every business-related expense you are entitled to.

Failing to do so means you are overpaying the government. A clear understanding of what qualifies as a deductible business expense can significantly lower your tax liability.

4. Missing the filing deadline

The IRD will issue a Profits Tax Return to you. This form has a strict filing deadline, typically one to three months after it’s issued.

Missing the deadline can lead to penalties and fines. Always file on time, even if you made a loss or believe you don’t owe any tax.

5. Failing to register your business

Even if you’re a freelancer working from a laptop, you must register your business with the Business Registration Office within one month of starting.

Operating without a valid Business Registration Certificate is an offense and can lead to fines.
