Vietnam's corporate income tax incentives combine a preferential rate for a defined period with periods of exemption and reduction. Under the Law on Corporate Income Tax 67/2025/QH15 the most favourable treatment is a rate of 10 percent for 15 years, available to qualifying new projects in fields such as high technology, supporting industries and certain infrastructure, to projects in areas with extremely difficult socio-economic conditions, and to high technology and science and technology enterprises. A rate of 17 percent for 10 years applies to a separate list: new projects in certain further sectors, new projects in areas with difficult socio-economic conditions, and new projects in economic zones located outside the areas that qualify for incentives. Exemption and reduction periods reach four years of exemption followed by nine years at a 50 percent reduction for the most favoured categories, and two years of exemption followed by four years at a 50 percent reduction for others.
Location now works differently. The 2025 law lists economic zones, high-tech parks, high-tech agricultural zones and digital technology parks among the qualifying areas, but a standard industrial zone is no longer an incentivised location in its own right. An investor who assumed that choosing an industrial zone secured an incentive needs to test the project against the sector and area criteria instead, and a project that already holds incentives granted under earlier rules should confirm how the transitional provisions apply to it.
The practical point is sequence. Eligibility depends on the business lines registered, the location, the scale of the investment and the technology involved, and those are fixed in the investment documents. We assess the incentive position before the licence application, model the corporate income tax cost of the realistic alternatives, and after licensing track the conditions that have to be maintained for the entitlement to hold.
