A Guide to Profits Tax for Unincorporated Business

Unincorporated Business

An unincorporated business is a business structure that doesn't have a separate legal identity from its owner(s). This means the owner(s) and the business are considered one and the same by law. There are two main types of unincorporated businesses:

  • Sole proprietorship: This is a business owned and operated by one person. It's the simplest and most common form of unincorporated business.

  • Partnership: This is a business owned by two or more people who share in the profits and losses of the business according to a predetermined agreement.

Here is one of the some key characteristics of unincorporated businesses:

  • Taxes: Profits of the business "pass through" to the owner(s) and are reported on their personal tax returns.

A Guide to Profits Tax for Unincorporated Business

In-Depth Guide to Profits Tax for Unincorporated Businesses in Hong Kong

In Hong Kong, unincorporated businesses are subject to profits tax just like corporations. 

Hong Kong's tax system offers a two-tiered profits tax regime for unincorporated businesses, making it an attractive location for entrepreneurs and sole proprietors. This guide explores the key aspects of profits tax for unincorporated businesses in Hong Kong:

Calculating Assessable Profits:

Unlike your accounting profits, profits tax is levied on your "assessable profits." Here's how to determine them:

  • Start with your accounting profit: This is the net profit figure after deducting all your business expenses from your gross income.

  • Add back non-deductible expenses: Certain expenses, like personal expenses or capital expenditures, cannot be deducted for tax purposes.

  • Adjust for capital allowances: You can claim depreciation on qualifying assets like machinery and equipment to reduce your taxable income. The IRD provides guidelines on depreciation rates [IRD website](IRD Hong Kong).

Profits Tax Rates and Waivers:

  • Two-tiered system:  The first HKD 2 million of your assessable profits are taxed at a concessional rate of 7.5%. Any profits exceeding this threshold are taxed at the standard rate of 15%.

  • Profits Tax Waivers: The government offers partial waivers to further reduce your tax burden. The current waiver for the 2023/24 tax year allows you to waive 100% of your tax liability, capped at HKD 3,000. Refer to the government website Hong Kong Profits Tax Rates for past and current waiver details.

Common Deductions and Allowances:

While Hong Kong's profits tax system offers a beneficial two-tiered rate and waivers for unincorporated businesses, there are specific rules for deductions and allowances. Here's a breakdown of some common ones:

Deductible Expenses:

  • Business Expenses: Only expenses incurred wholly, exclusively, and necessarily for the purpose of generating your business income are deductible.  This includes:

  • Rent for business premises

  • Salaries and wages paid to employees

  • Utilities and communication costs

  • Office supplies and equipment (subject to depreciation rules)

  • Cost of goods sold (for businesses that buy and sell inventory)

  • Travel expenses related to business operations

  • Professional fees (accounting, legal)

Non-deductible Expenses:

  • Personal Expenses: Expenses for private purposes, like clothing, meals not related to business meetings, or entertainment unrelated to business development, cannot be deducted.

  • Capital Expenditures:  The cost of acquiring assets with a long lifespan (buildings, machinery) cannot be deducted entirely in a single year. Instead, depreciation allowances are claimed over their useful life.

  • Fines and Penalties:  Fines, penalties, and any other liabilities incurred due to non-compliance with regulations are not deductible.

Special Allowances:

  • Mandatory Contributions: Contributions to Mandatory Provident Fund (MPF) schemes for yourself and your employees are deductible.

  • Bad Debts:  Debts that you can prove are irrecoverable can be written off as bad debts and deducted from your taxable income.

  • Research & Development:  Expenditures on research and development activities relevant to your business may qualify for tax deductions under specific government programs.

Filing Tax Returns:

  • Registration:  You don't need to register a business specifically for profits tax purposes. However, you'll need to register for Business Registration Certificate (BRC) if your business generates an annual turnover exceeding HKD 1 million.

  • Tax Return: If you have assessable profits, you must file a tax return with the Inland Revenue Department (IRD) by the deadline (typically July 15th of the following assessment year). You can use form BIR52 ("Profits Tax Return - Persons Other Than Corporations") [IRD website](IRD Hong Kong).

  • Payment:  Profits tax is payable by the deadline for filing your tax return.


  • Keep detailed records of your income and expenses to accurately calculate your assessable profits.

  • File your tax return on time to avoid penalties.

Tax Return Procedures

Here's a breakdown of the tax return procedures for unincorporated businesses in Hong Kong:


  • Unincorporated businesses typically don't need separate registration for profits tax purposes. However, you might need a Business Registration Certificate (BRC) if your business turnover exceeds HKD 1 million annually. You can register for a BRC online through the Business Registration Office

Filing the Tax Return:

  • Who Needs to File:  If you have assessable profits from your unincorporated business in Hong Kong, you are obligated to file a tax return with the Inland Revenue Department (IRD).

  • Deadline:  The deadline for filing your tax return is typically July 15th of the year following the assessment year. For example, the tax return for profits earned in the 2023/24 assessment year is due on July 15, 2024. However, sole proprietors of unincorporated businesses get an extension until August 2, 2024. You can enjoy an additional one-month automatic extension if you file electronically.

  • Form to Use:  The standard form for unincorporated businesses is the BIR52 ("Profits Tax Return - Persons Other Than Corporations") [IRD website](IRD Hong Kong). You can download the form and instructions from the IRD website.

  • Filing Methods: You can file your tax return electronically through the IRD's online portal or submit a paper return by mail. Electronic filing is generally encouraged for faster processing and potential extension benefits.

Preparing the Return:

  • Gather Documentation:  You'll need detailed records of your business income and expenses throughout the year. This includes bank statements, invoices, receipts, and any other documents that support your income and claimed deductions.

  • Calculate Assessable Profits:  As explained earlier, your assessable profits might differ from your accounting profits. Refer to the guide on calculating assessable profits (including adding back non-deductible expenses and claiming depreciation allowances) to determine the taxable amount.

  • Claim Deductions and Allowances:  Identify and claim all eligible deductions and allowances you're entitled to, as mentioned in the previous section on common deductions and allowances.

  • Complete the Form:  Carefully fill out the BIR52 form with your business information, income details, expenses, deductions, and calculated tax liability.

Payment of Tax:

  • Deadline:  The tax payment is typically due by the same deadline as filing the return (July 15th or August 2nd for sole proprietors, with a potential one-month extension for e-filing).

  • Payment Methods: You can make tax payments electronically through the IRD's online portal, via bank transfers, or by cheque.

Additional Tips:

  • Keep accurate and well-organized records throughout the year to simplify tax return preparation.

  • File your return on time to avoid penalties for late filing.

By understanding these key points, you can effectively manage your profits tax obligations as an unincorporated business owner in Hong Kong.
