Hong Kong SAR

Foreign tax relief

As a relief from double taxation, unilateral income exemption is available for employment income derived from services rendered outside Hong Kong SAR and where tax similar to the nature of Hong Kong salaries tax has been charged and paid on that income in the territory in which the services are rendered. This is applicable up to the year of assessment 2017/18.

Starting from the year of assessment 2018/19, the income exemption claim is only available where foreign tax has been paid in a non-CDTA jurisdiction for services rendered in that jurisdiction.

Technically, this income exemption applies to both Hong Kong and non-Hong Kong employments. However, such exemption is practically not applicable to taxpayers with a non-Hong Kong employment as only income of services rendered in Hong Kong SAR is taxable in cases of non-Hong Kong employment.

A foreign tax credit is available to Hong Kong tax residents in respect of income derived from and taxable in a jurisdiction that has entered into a CDTA with Hong Kong SAR and the same income is subject to tax in Hong Kong SAR. Salaries taxpayers are required to take all reasonable steps to minimise the foreign tax payable before making a claim for tax credit in Hong Kong SAR.

Tax treaties

Currently, Hong Kong SAR has entered into 54 tax treaties with different jurisdictions as shown in the following table. All of the following treaties have been ratified and are effective unless indicated otherwise in the notes below.

Note

1. The treaty is effective from the year of assessment 2026/27 in Hong Kong SAR.
2. The treaty is effective from the year of assessment 2025/26 in Hong Kong SAR.
3. The treaty is pending ratification.

Hong Kong SAR has not entered into any social security agreements with any jurisdictions as there is no social security tax in Hong Kong SAR.

Estate and gift tax conventions

Hong Kong SAR has not entered into any estate and gift tax conventions because estate duty was abolished in 2006 and it does not have a gift tax.

Tax information exchange agreements (TIEAs)

Currently, Hong Kong SAR has entered into seven TIEAs with different jurisdictions as shown in the following table.

All of the above TIEAs are ratified and effective.

In addition to the signing of the Hong Kong SAR-United States TIEA in March 2014, Hong Kong SAR signed a Model 2 intergovernmental agreement (IGA) with the United States in November 2014 to facilitate compliance with the Foreign Account Tax Compliance Act (FATCA) by financial institutions in Hong Kong SAR.

Automatic exchange of information (AEOI) / Common Reporting Standard (CRS) regime

Hong Kong SAR has put in place a legislative framework to implement the AEOI/CRS regime. Reportable financial institutions are required to identify the reportable financial accounts held by (i) tax residents of reportable jurisdictions or (ii) passive non-financial entities whose controlling persons are tax residents of reportable jurisdictions in accordance with the specified due diligence procedures, collect the required information of those reportable accounts, and furnish such information to the HKIRD. Such information will then be exchanged on an annual basis.

There are 129 reportable jurisdictions effective from 1 January 2020. However, Hong Kong SAR will only conduct AEOI with a reportable jurisdiction when an agreement is in place with that reportable jurisdiction to provide the basis for exchange.

As of November 2025, Hong Kong SAR has activated exchange relationships for CRS purposes with over 80 jurisdictions based on either a bilateral or multilateral competent authority agreement for CRS.
