When Can a Company Lose Its Corporate Tax Incentives in Vietnam?

A company in Vietnam can lose access to corporate income tax (CIT) incentives when it no longer satisfies the conditions attached to the qualifying investment project or income. A company may also face additional CIT where preferential treatment was applied to income that did not qualify in the first place.

Vietnam’s current CIT framework links incentives to factors including qualifying sectors, locations, and project characteristics. Existing beneficiaries may also retain incentives under transitional rules, while expansion projects are subject to specific eligibility conditions.

How can investment changes affect existing CIT incentives?

Vietnamese CIT incentives are generally linked to qualifying sectors, activities, geographical areas, or investment projects. A company carrying out both incentivized and non-incentivized activities cannot simply apply preferential treatment to all its taxable income.

This becomes relevant when a foreign-invested company adds a business activity that does not qualify for the incentive applied to its existing project. The new activity does not automatically remove the incentive from qualifying income, but income outside the qualifying activity cannot receive preferential treatment merely because it is earned by the same legal entity.

Vietnam also has specific rules for expansion investments. An operating project in an incentivized sector or location that increases scale or capacity, modernizes technology, or makes qualifying environmental improvements may receive incentive treatment on additional income. Where the original project remains within its incentive period, a qualifying expansion can use the remaining incentives available to that project.

Different rules apply where the original project’s incentives have expired. A qualifying expansion can receive exemptions and reductions, but not a preferential CIT rate, if it meets at least one of three tests: additional fixed assets of at least VND 40 billion (US$1.5 million) for expansion in an incentivized sector or VND 20 billion (US$760,000) for expansion in an incentivized location; an increase in fixed-asset value of at least 20 percent compared with the pre-expansion level; or an increase in designed capacity of at least 20 percent.

For these qualifying expansions, the exemption or reduction period begins in the year the registered expansion capital has been fully disbursed, and the project generates income. If no taxable income is generated during the first three years from the year the registered expansion capital is fully disbursed, the exemption or reduction period begins in the fourth year. An expansion that does not fully disburse its registered capital does not qualify for these incentives.

Example: Expanding beyond an incentivized activity

Consider a foreign-invested manufacturer operating a Vietnamese project that qualifies for CIT incentives. The company later adds a separate business activity that does not qualify for the same preferential treatment.

The company does not necessarily lose the CIT incentive applicable to income from its original qualifying activity. However, it cannot automatically apply that treatment to profits generated by the new activity. If it does so, the resulting tax exposure concerns the non-qualifying income rather than the continued eligibility of the original project.

What happens to CIT incentives after a corporate restructuring?

Vietnam distinguishes between continuing an existing incentive and qualifying for incentives available to a new or expanded investment project. A merger, acquisition, division, project transfer, or other restructuring should not automatically be treated as creating a fresh incentive entitlement.

This distinction is particularly important for expansion projects. Expansion incentives are not available where the expansion results from the merger or acquisition of an existing enterprise or investment project. At the same time, restructuring does not necessarily result in the automatic disappearance of every incentive previously available to the business.

Assess How Project Changes Could Affect Your Vietnam Tax Incentives

The tax issue is whether the remaining incentive can continue under the rules applicable to the transaction, rather than whether the reorganized investment can restart an incentive period available to a new project.

What happens when an incentive was incorrectly claimed?

A company that legitimately qualified for an incentive before its circumstances changed is in a different position from a company that applied for preferential treatment without meeting the applicable requirements.

Where an incentive was incorrectly claimed, CIT that should have been paid can become subject to reassessment under Vietnam’s tax administration framework. Depending on the circumstances, late-payment interest and administrative penalties may also apply.

The exposure can extend across multiple tax periods where the same treatment has been consistently applied. This can occur, for example, where a company incorrectly classified income as incentivized or treated an expansion or reorganized project as qualifying when the applicable conditions were not satisfied.

How can the tax authorities challenge an existing CIT incentive?

Vietnamese taxpayers generally self-assess their eligibility for CIT incentives, leaving the underlying treatment open to review by the tax authorities.

A challenge can concern eligibility: whether the investment project or activity satisfies the requirements for the preferential rate, exemption, or reduction being claimed. It can also concern scope: whether income reported as incentivized is covered by that treatment.

The distinction can produce different outcomes. The authorities may conclude that the project itself does not qualify for the incentive, or they may accept the incentive while determining that a smaller amount of the company’s income is entitled to preferential treatment.

A company does not necessarily have to lose its entire CIT incentive for additional tax exposure to arise.
