A significant advantage of setting up a company in Hong Kong is its favorable tax regime. The city's simple and low taxation system is a major draw for entrepreneurs and corporations from around the globe. However, to truly benefit from this system, one needs to grasp its fundamental principles. In this article, we break down the essentials of form a company in Hong Kong.

1. Principle of Territorial Taxation
One of the pillars of Hong Kong's tax system is the territorial principle:

Scope: Only profits that arise in or are derived from Hong Kong are subject to tax. Profits sourced outside of Hong Kong are not taxed.

Determination: The source of profits can sometimes be a contentious issue. Factors such as contract negotiation, execution, and the location of the company's primary activities play a role.

2. Profit Tax Rates
The tax rates are relatively low in comparison to global standards:

Corporations: The tax rate for corporate entities stands at 16.5%.

Unincorporated Businesses: For businesses like sole proprietorships and partnerships, the rate is 15%.

Two-tier Regime: To foster entrepreneurship, the first HKD 2 million of assessable profits for companies is taxed at a reduced rate, while the remainder is taxed at the regular rate.

3. No VAT/GST, Sales Tax, or Capital Gains Tax
Hong Kong does not impose:

Value-added tax (VAT) or goods and services tax (GST).

Sales tax on goods and services.

Tax on capital gains received from the sale of business assets or investments.

4. Dividend Income
No Tax on Dividends: Dividends received by a Hong Kong company from another local company are tax-exempt.

Foreign Dividends: These are generally not taxable, adhering to the territorial principle.

5. Deductible Expenses
For an expense to be deductible, it must be incurred in the production of assessable profits:

Common Deductions: Expenses like rent, salaries, and interest on business loans are often deductible.

Non-deductible: Capital expenditures, domestic or private expenses, and distributions to owners or shareholders.

6. Double Taxation Agreements (DTAs)
To prevent businesses from being taxed in both Hong Kong and an overseas jurisdiction, Hong Kong has established numerous DTAs:

Benefits: These agreements provide clarity on taxing rights and often offer tax reliefs or exemptions.

Countries Covered: Hong Kong has DTAs with many countries, so it's vital to check if the country you are doing business with is on the list.

7. Annual Filing and Deadlines
Companies must file a Profits Tax Return annually:

Deadlines: Generally, the deadline for filing is within one month from the date of issue of the tax return. Extensions might be available if enrolled in the Inland Revenue Department's Electronic Filing scheme.

Audited Accounts: Along with the tax return, companies usually need to submit audited financial accounts.
