Knowledge of how taxes are assessed in Hong Kong is imperative to every businessman, whether it is your Hong Kong SME or your business owned from abroad. Every year, the Inland Revenue Department (IRD) calculates your profits tax assessment according to your reported income and expenses. This determines your liability for tax payments or if there is an overpayment.
In this guide, FastLane HR’s team of tax professionals walks you through a step-by-step explanation of how the profits tax assessment is done. Some questions you may have include what it is, how it’s assessed, when it is due, and how to deal with a re-asessment.
How Does a Hong Kong Business Pay Taxes?
A tax assessment is the notification given by the IRD of the amount of tax that is due for a year of assessment.
For business taxpayers, this means mainly the Profits Tax Assessment of your assessable profits. This is your accounting profit adjusted for certain deductions and exemptions applicable to your business.
All business entities that engage in trade, profession, or business in Hong Kong have to pay profits tax. This is applicable regardless of their location of incorporation. This means that companies owned overseas with business in Hong Kong have to pay profits tax.
A correct tax assessment benefits you in the following manner:
- Avoid penalties for under-declaration
- Estimate and plan for provisional tax payments
- Optimize tax effectiveness with deductibility
Essential Elements of Profits Tax Assessment

Tax Rates

The IRD is able to raise an additional assessment within six (or ten) years at the conclusion of a YA in cases of fraud. It is important to maintain proper and transparent documentation to prevent such kinds of issues.
