Vietnam’s New Capital Gains Tax Rules For Foreign Enterprises
On 14 June 2025, the National Assembly passed the amended Corporate Income Tax Law 2025 (CIT Law 2025). Among other things, this legislation is expected to bring significant changes in determining the method of calculating tax for capital transfer and securities transfer transactions (Capital Gains Tax) undertaken by foreign companies. This post aims to provide a comprehensive and clear overview by analyzing and comparing these new regulations with those stipulated in the Corporate Income Tax Law 2008 (CIT Law 2008).
1) Definition of Taxable Income Arising in Vietnam for Foreign Companies
A key area of adjustment in the CIT Law 2025 relates to the definition of taxable income arising in Vietnam for foreign companies, making it more transparent.
Under the CIT Law 2008, the specific definition of such income was not explicitly clarified within the law itself; rather, it was detailed in Decree 218/2013 guiding the CIT Law 2008. In contrast, the CIT Law 2025 has directly incorporated this definition, clearly stating that taxable income arising in Vietnam for foreign companies is income originating from Vietnam, irrespective of the location where business activities are conducted.
