How to Pay Corporate Tax in Hong Kong – A Practical Guide

Hong Kong has a structured system for paying corporate tax. Knowing how to pay helps you avoid penalties, interest, or misdirected payments.

1. How are taxes calculated
Hong Kong follows a territorial basis of taxation, meaning only income sourced in Hong Kong is taxable. The IRD will convey both the below taxes in the assessment letter issued to the corporate:

• Final Tax – For the year just ended.

• Provisional Tax – An advance payment for the current year, based on your previous year’s income.

What is Provisional Tax?
Provisional tax is essentially a prepayment for the upcoming year’s tax liability. When the next year’s assessment is issued, provisional tax already paid will be deducted from your final bill.

First-time taxpayers do not have a previous year’s provisional tax to offset, so they may need to pay both the final tax for the current year and the provisional tax for the next year together.

Example: How Final Tax and Provisional Tax Work in Hong Kong

Let’s say for the Financial Year (FY) 2024–25 (i.e., income earned from 1 April 2024 to 31 March 2025), the Inland Revenue Department (IRD) issues you a Tax Assessment showing that your final tax liability for the year 2024–25 is HKD 5,000, and your provisional tax liability for the year 2025–26 is HKD 7,000.

Now, depending on when and how you have already made provisional tax payments, the calculation and adjustment work as follows:

Case 1 – Provisional Tax Paid During FY 2024–25
Suppose you paid HKD 2,000 as provisional tax between April 2024 and March 2025. This amount will be credited against your 2024–25 final tax liability of HKD 5,000.

• Final Tax for 2024–25: HKD 5,000

• Less: Provisional Tax already paid: HKD 2,000

• Final Tax still payable for 2024–25: HKD 3,000 (HKD 5,000- HKD 2,000)

• Provisional Tax for 2025–26: HKD 7,000

• Total Tax payable for 2024–25 & 2025–26 after adjusting provisional tax of 2024–25: HKD 10,000 (HKD 3,000+ HKD 7,000)

Case 2 – Provisional Tax Paid After the Year-End
If the same HKD 2,000 was paid after 31 March 2025 (for example, in April 2025), it will not be credited against your 2024–25 final tax. Instead, the IRD will treat this as provisional tax for the next tax year (2025–26).

• Final Tax for 2024–25: HKD 5,000

• Less: Provisional Tax paid between April 2024–March 2025: Nil

• Final Tax still payable: HKD 5,000 (in full)

• The HKD 2,000 paid in April 2025 will be used to offset your 2025–26 final tax liability once assessed in the following year.

💡 Tip: Always pay on or before the due date. Late payments can lead to immediate recovery actions by the IRD.

2. Corporate Tax Rates

Note: For the 2024/25 year, 100% of profits tax is waived, subject to a ceiling of HKD 1,500.

3. Key Takeaways

• Wait for the IRD’s official assessment before making any payment.

• Provisional tax is an advance payment for the next year’s liability.

• Pay on time to avoid interest, penalties, or enforcement actions.

• Use the shroff number exactly as stated.

By understanding these rules and paying through the correct channels, you can remain compliant and avoid unnecessary administrative issues in Hong Kong’s tax process.
