Tax Calculation Summary
Understanding Two-Tiered Tax Rates Eligibility
×What are Two-Tiered Profits Tax Rates?
Hong Kong's two-tiered profits tax system offers reduced tax rates on the first HKD 2 million of assessable profits:
- Corporations: 8.25% on first HKD 2M, then 16.5% on the balance
- Unincorporated businesses: 7.5% on first HKD 2M, then 15% on the balance
Do I Qualify?
Most businesses automatically qualify UNLESS one of these applies:
If your company has connected entities (see below), only ONE entity in the group can use the two-tiered rates in any given year.
What are "Connected Entities"?
- One entity controls the other (>50% ownership or voting rights)
- Both entities are controlled by the same person or entity
- The same individual operates multiple sole proprietorships
- They are part of the same corporate group
Who CANNOT Use Two-Tiered Rates?
- Entities already benefiting from preferential tax regimes
- Companies where another connected entity has already claimed the two-tiered rates
- Certain regulated financial institutions
Understanding Provisional Tax Payments
×What is Provisional Tax?
Provisional tax is Hong Kong's prepayment tax system. Instead of waiting until the end of the year to collect all your tax, the IRD requires you to pay tax in advance based on your previous year's profits.
Payment Schedule
- First installment: 75% of the estimated tax (usually due in November/December)
- Second installment: 25% of the estimated tax (usually due in April/May)
Can I Reduce Provisional Tax?
Yes! If you expect your current year profits to be significantly lower than last year, you can apply to the IRD to reduce your provisional tax by submitting Form IR1121.

Understanding Hong Kong's Corporate Profits Tax System
Hong Kong operates one of the most competitive and straightforward tax systems in Asia. The city’s territorial tax system means that only profits arising in or derived from Hong Kong are subject to taxation. This makes Hong Kong an attractive destination for international businesses and regional headquarters.
Under Hong Kong’s two-tiered profits tax rates regime, introduced in 2018/19, qualifying corporations benefit from a reduced rate of 8.25% on the first HKD 2 million of assessable profits, with the balance taxed at 16.5%. For unincorporated businesses, the rates are even more favorable at 7.5% and 15% respectively.

Frequently Asked Questions
Q: How do I know if I qualify for the two-tiered tax rates?
Most businesses automatically qualify for Hong Kong’s two-tiered profits tax rates unless you are part of a group of connected entities. If your company has connected entities (companies with common ownership or control), only ONE entity in the group can claim the two-tiered rates in any given year. Entities already benefiting from other preferential tax regimes (such as corporate treasury centers or aircraft leasing) are also excluded.
Q: What counts as "assessable profits" in Hong Kong?
Assessable profits are your taxable profits after deducting allowable business expenses but before applying capital allowances and other special deductions. They must arise in or be derived from Hong Kong from a trade, profession, or business carried on in Hong Kong. Generally, all costs and expenditures incurred in generating taxable profits are eligible for deductions.
Q: When is the Hong Kong profits tax return due?
The Inland Revenue Department typically issues profits tax returns on the first working day of April each year. The standard filing deadline is one month from the issue date. However, if you use a tax representative or file electronically, you can get an extension. Companies with different accounting year-ends may have different deadlines, with those ending in March generally receiving the longest extensions.
Q: What is provisional tax and how does it work?
Hong Kong operates a provisional tax system where companies must prepay tax based on the current year’s estimated profits. The provisional tax for a year is based on the assessable profits of the preceding year. This means you’ll typically pay tax in two installments: 75% of the estimated tax payable, followed by 25% several months later. Any overpayment is refunded or offset against future liabilities.
Q: Can foreign-sourced income be taxed in Hong Kong?
Generally, foreign-sourced income is not taxable in Hong Kong due to its territorial tax system. However, under the refined Foreign-Sourced Income Exemption (FSIE) regime effective from 2023, certain types of foreign-sourced income (interest, dividends, disposal gains, and IP income) received by multinational enterprise entities in Hong Kong may be deemed taxable unless specific economic substance requirements are met.
Q: What expenses are NOT deductible for Hong Kong profits tax?
Non-deductible expenses include: domestic or private expenses, capital expenditures (except those with specific allowances), amounts recoverable through insurance, rent for premises not used for profit-generating activities, taxes payable under the Inland Revenue Ordinance (except salaries tax for employees), and excessive remuneration to proprietors or partners.
Q: How accurate is this calculator?
Our calculator uses the official Hong Kong tax rates and deduction rules for the 2025/26 tax year. While it provides a reliable estimate for planning purposes, your actual tax liability may vary based on specific circumstances, IRD assessments, and detailed examination of your accounts. This tool does not constitute professional tax advice. For definitive tax advice tailored to your situation, we recommend consulting with a qualified tax professional such as a Hong Kong CPA or tax advisor.
Q: What records do I need to keep for Hong Kong tax purposes?
The Inland Revenue Department requires businesses to maintain all accounting records, receipts, invoices, and supporting documents for at least 7 years. Private companies incorporated in Hong Kong must also have their financial statements audited by a Hong Kong Certified Public Accountant (CPA). Proper record-keeping is essential for tax compliance and can help you avoid penalties during audits.
