Vietnam's government has issued Decree 398/2026/ND-CP, cutting by 30% the personal income tax and corporate income tax payable for the 2026 and 2027 tax years by business individuals and enterprises whose annual revenue does not exceed 10 billion dong, VietnamPlus reported. The decree took effect on 29 October 2026 and implements a National Assembly resolution. Value-added tax is not covered.

Who qualifies

KBVN+ summarises the decree:

ItemIndividuals and household businessesEnterprises and other organisations
Tax cutPersonal income tax on business incomeCorporate income tax
Reduction30% of tax payable30% of tax payable
Years2026 and 20272026 and 2027
Revenue cap10 billion dong a year10 billion dong a year
How to claimIn quarterly, half-yearly or annual returnsSelf-assessed in quarterly provisional payments
If revenue exceeds the capRepay the reduction, no late-payment interest up to the filing deadline for that periodPay the shortfall; late interest under tax law

Eligible individuals are resident business owners, including registered household business heads or authorised household representatives, regardless of how their tax is calculated. Parties that withhold or file tax on their behalf also get the 30% cut. For companies, the scheme covers enterprises, cooperatives, public service units and other organisations with business income. Where a firm already enjoys tax incentives, the 30% applies to the tax remaining after those incentives.

Fine print

The 10 billion dong threshold is based on total actual revenue for the year. For companies that includes sales, services, financial income and other income, plus revenue from branches and dependent units. Firms created by splitting a business after the resolution took effect are excluded if their combined revenue exceeds the cap. If an audit raises the tax owed, the extra amount still qualifies for the cut, provided the revenue condition is met.

What it means

The measure targets small traders and micro firms. In simple terms, an eligible business that owes 100 million dong in income tax for a year would pay 70 million dong. Owners need to watch cumulative revenue: once it passes 10 billion dong, individuals must adjust their filing in that period and pay back the reduction.

What comes next

With the decree already in force, individuals can include the reduction in upcoming tax returns, and companies can apply it to their quarterly provisional corporate income tax. The relief covers the 2026 and 2027 tax years.
