Tax Substance in Hong Kong

5 January 2021

It is sometimes argued that a company incorporated under HK Law (“HK Co”) will (a) automatically be regarded as a Hong Kong tax resident for tax purpose; and (b) only be subject to profits tax in Hong Kong but not in other tax jurisdictions. However, one has to be well aware that if HK Co lacks (has insufficient) ‘tax substance’ or ‘economic substance’ in Hong Kong, HK Co might be considered as having taking up its tax residency in the jurisdiction that has ‘more’ tax substance. As a result, HK Co becomes potentially subject and liable to Hong Kong and foreign corporate income tax at the same time, thereby incurring double taxation. In addition, HK Co might not be entitled to tax benefits (such as reduced withholding tax rates on dividend, interest and royalties) granted under Hong Kong double tax treaties (‘DTAs’).


What is tax substance?


There is no definition of tax substance under Hong Kong tax laws. In determining whether HK Co maintains tax substance in Hong Kong, tax authorities generally look at every relevant fact and circumstance of HK Co. The relevant factors include but are not limited to the following:

(i) whether the business is managed and controlled in Hong Kong

(ii) whether the business is carried out in Hong Kong and if yes, what is the nature of business?

(iii) whether the directors and other senior management personnel reside in Hong Kong and their respective roles and responsibilities?

(iv) whether directors’ meetings are held in Hong Kong?

(v) whether physical office(s)/warehouse(s)/other forms of establishments is maintained in Hong Kong?

(vi) whether any staff is employed in Hong Kong?

(vii) whether and how many Hong Kong bank accounts are maintained?

(viii) whether fixed assets(s) and cash are kept in Hong Kong?

The more of the above activities take place in Hong Kong by the HK Co, the stronger a claim for having sufficient tax substance by the HK Co in Hong Kong can be ascertained.


Adverse effects of insufficient substance in Hong Kong


As mentioned above, inadequate tax substance maintained by HK companies in Hong Kong will potentially result into two major unfavourable consequences:

(i) Exposure to corporate income tax in foreign jurisdictions

The place of management and control of a company is usually one of the critical factors in determining tax residency. Therefore, HK Co, although incorporated in Hong Kong, but managed and controlled from out a foreign tax jurisdiction, is likely to be regarded as a tax resident in that foreign tax jurisdiction whereby it then will also be exposed to foreign corporate income tax.

(ii) Failure to obtain a certificate of resident status (“the Certificate”)

In order to enjoy certain tax preferential treatments under the Hong Kong DTAs signed with 35 tax jurisdictions, HK Co has to be qualified as a Hong Kong tax resident. This assessment is made by the Hong Kong Inland Revenue Department (“HK-IRD”) and upon a positive assessment, results into the issuance of the Certificate. One of the HK-IRD’s major considerations in assessing the application for the Certificate by HK Co is whether HK Co maintains sufficient tax substance in Hong Kong. It is observed that the HK-IRD has become more and more stringent in reviewing the application for the Certificate in recent years, probably due to international pressure on combating treaty shopping.

For the purpose of obtaining the Certificate, it is required to complete an application form prescribed by the HK-IRD, in which applicants have to provide, amongst others, their particulars and details regarding the tax treaty benefits to be claimed as well as answer a number of questions in connection with tax substance as mentioned in items (i) to (viii) of paragraph 2 above.

In case the information supplied in the application form is not sufficient for assessing the application for the Certificate, the HK-IRD would probably issue follow-up enquiry letter(s) to applicants requesting for further detailed information/supporting documents.




It is vital for HK Co to keep sufficient tax substance in Hong Kong with a view to mitigate its foreign tax exposures as well as obtain the Certificate from the HK-IRD smoothly and successfully for the purpose of tax treaty benefits. One should note that further to implementation of automatic exchange of information/Common Reporting Standard in short CRS in the near future, tax information will be more and more transparent among tax authorities of various jurisdictions.
