Short answer. Vietnam's standard corporate income tax rate is 20%, applied to assessable income for most businesses. That headline figure is the starting point for budgeting, not the end of the analysis: qualifying projects in encouraged sectors — high-tech, software development, education, healthcare, environmental protection, scientific research, agricultural and aquatic processing, renewable energy, and infrastructure — or in encouraged locations, such as approved industrial parks, certain high-tech parks, and economically disadvantaged areas, can access preferential rates as low as 10%, sometimes running for ten years or, for certain qualifying projects, indefinitely. These preferential rates are frequently paired with a tax holiday structure — commonly a period of full exemption followed by a further period of 50% reduction — though the exact combination depends on the specific incentive category. Once a foreign-owned entity is operating, transfer-pricing documentation becomes a recurring compliance obligation for related-party transactions, and should be budgeted for as an ongoing cost rather than treated as a one-time set-up item.
The standard rate, and who actually pays it
Twenty percent is Vietnam's standard corporate income tax rate and applies to the assessable income of most businesses operating in the country, foreign-owned or otherwise. For an investor budgeting a new Vietnamese subsidiary, this is the correct baseline assumption unless the specific business qualifies for one of the preferential regimes described below — and confirming eligibility, rather than assuming it, is the first real piece of tax planning work in any market-entry engagement.
Preferential rates and tax holidays for qualifying projects
Vietnam operates a two-lever incentive system: preferential rates and tax holidays, which can apply together. Preferential CIT rates, reduced to between 10% and 17% depending on the specific incentive category, are available to projects in encouraged sectors (high-tech enterprises, software development, education, healthcare, environmental protection, scientific research, agricultural and aquatic product processing, renewable energy, and infrastructure development) or encouraged locations (economically disadvantaged areas, certain economic zones, approved high-tech parks, and approved industrial parks). These preferential rates can run for ten years or, for certain qualifying categories, indefinitely, rather than being a short-term concession. Separately, many qualifying projects also receive a tax holiday — a defined period, commonly two to four years, of full exemption from CIT, followed by a further period at a 50% reduction — layered on top of the preferential rate itself. The specific combination of rate, holiday length, and reduction period depends on the sector, location, and scale of the qualifying investment, and should be confirmed against the specific project rather than assumed from a comparable case.
Transfer pricing: a recurring obligation, not a one-time item
Once a foreign-owned company in Vietnam begins transacting with related parties — a parent company, an affiliate, or a fellow subsidiary — transfer-pricing documentation becomes a recurring annual compliance requirement, not a one-time set-up cost. This is a routine budgeting item for any foreign-invested entity with cross-border related-party dealings (management fees, intercompany services, goods transfer pricing), and is worth building into the operating cost model from year one rather than discovering as a compliance surprise once the entity is already trading.
Is Vietnam's 20% corporate income tax rate the same for foreign-owned and domestic companies?
Yes, the standard 20% rate applies equally regardless of ownership; foreign ownership itself is not what triggers a different rate — sector and location-based incentive eligibility is.
How much can a qualifying project actually reduce its effective tax rate?
Preferential rates can go as low as 10%, and when combined with an initial multi-year exemption period followed by a 50% reduction period, the effective early-years tax burden can be substantially below the 20% standard rate for a genuinely qualifying project.
Do all foreign-invested companies need transfer pricing documentation?
Only those with related-party transactions — a parent company, affiliate, or fellow subsidiary — need to maintain transfer-pricing documentation; a company with no cross-border related-party dealings does not have the same recurring obligation.
Can a company qualify for incentives based on location alone, without being in an encouraged sector?
Yes, encouraged-location incentives (certain economic zones, high-tech parks, approved industrial parks, and economically disadvantaged areas) can apply independently of sector, though sector and location incentives can also combine for certain qualifying projects.
How long do preferential CIT rates typically last?
Ten years for many qualifying categories, and indefinitely for certain highly qualifying projects — this is a materially longer commitment than a short-term tax break, and worth factoring into a multi-year financial model.
How does JMT Private & Partners assist with tax incentive planning?
JMT assesses a project's eligibility for sector and location-based incentives during the pre-investment feasibility stage, and coordinates with tax advisory partners on transfer-pricing documentation once the entity is operational, as part of its Business Related Advisory service line.
