Business Taxes in Vietnam: Essential Guide

Introduction

Business taxes in Vietnam in 2026 is becoming a key factor that every company needs to understand when operating in the Vietnamese market. In the context of increasingly transparent but also stricter tax policies, correctly understanding the regulations not only helps businesses avoid legal risks but also optimize costs effectively. This article provides a comprehensive and up-to-date overview of important taxes and their practical application in 2026.

2026: When Tax Compliance Is No Longer Optional

For many years, some businesses focused mainly on “paying enough” tax. In 2026, that mindset no longer works.

Tax authorities are now paying closer attention not only to final tax figures but also to how businesses recognize revenue, record expenses, and manage cash flow. The enforcement approach has become more detailed and data-driven.

With the introduction of the Law on Corporate Income Tax No. 67/2025/QH15, there is tighter control over deductible expenses, related-party transactions, and cross-border activities. At the same time, mandatory e-invoicing and updated accounting requirements have made financial data far more transparent.

As a result, financial statements are no longer just internal records—they are a key part of tax compliance. Even small inconsistencies can trigger significant tax exposure if not handled properly from the beginning.

Corporate Income Tax: More Than Just 20%

Many people often think that corporate income tax is a flat 20% rate applied to all businesses. In reality, this isn’t entirely true, as the tax rate depends on the size and industry of the business.

For small businesses, current policies offer clear support. If annual revenue does not exceed 3 billion VND, the tax rate can be reduced to 15%. If revenue is between 3 billion and 50 billion VND, the applicable tax rate is 17%. This helps small businesses reduce financial pressure during their growth phase.

Conversely, some specialized industries such as oil and gas extraction or rare earth resources will face higher tax rates, potentially ranging from 25% to 50% depending on the project.

However, what businesses need to pay attention to is not just the tax rate, but also how to determine taxable profit. If expenses lack proper invoices or documentation, or do not meet regulations, they may be disallowed. When expenses are disallowed, taxable profit increases, meaning the amount of tax payable also increases. This is why many businesses are subject to back taxes even though they did not apply the wrong tax rate.

Value Added Tax (VAT): Direct Impact on Business Cash Flow

VAT is often thought of as simple because the common rate is 10%. However, in practice, it is the tax most prone to errors because it relates to each invoice and daily transaction.

Besides the 10% rate, some essential goods and services are subject to a lower rate of 5%. For export activities or providing services abroad, if conditions are met, the tax rate may be 0%.

Currently, the policy of reducing VAT from 10% to 8% is still in effect until December 31, 2026, according to current regulations, to support businesses and stimulate the market. However, not all industries benefit from this reduction. Sectors such as banking, real estate, telecommunications, and mining still maintain the old tax rate. If the industry is incorrectly identified, businesses can easily apply the wrong tax rate without realizing it.

Another important point is the mandatory use of electronic invoices. Almost all transactions are recorded instantly on the system, making things more transparent but also meaning that errors are harder to correct than before. Therefore, businesses need to check carefully from the outset to avoid risks later on.

Personal Income Tax: Small Mistakes, Big Consequences

In many businesses, personal income tax is often not given the proper attention because it is simply a deduction and payment made on behalf of employees. However, this “habitual” practice makes mistakes more likely.

Currently, personal income tax is calculated according to a progressive tax rate from 5% to 35% depending on the taxable income level. At the same time, from 2026, the personal allowance has been adjusted upwards, reducing the tax burden for many employees.

For foreign workers, the calculation method varies depending on the length of their stay in Vietnam. If they stay for 183 days or more in a year, they are considered resident individuals and are subject to the same tax rate as Vietnamese citizens. Conversely, if they do not meet the residency requirements, income earned in Vietnam will be taxed at a fixed rate of 20%.

In reality, the problem often lies not in the tax rate itself, but in the method of calculating income. Items such as bonuses, allowances, subsidies, or other benefits can easily be overlooked if not processed correctly. When tax authorities conduct an audit, these amounts may be recalculated, leading to back taxes. Therefore, businesses need to tightly control the payroll calculation process to avoid future risks.

Special Consumption Tax: Cost Pressure in Selected Industries

Special consumption tax (SCT) applies only to certain goods and services, but where it applies, the financial impact can be significant.

Products such as alcohol, tobacco, and automobiles are subject to high tax rates. For example, alcohol may be taxed between 35% and 65%, tobacco around 75%, and automobiles up to 150% depending on engine size.

From 2026, SCT policies are being further reviewed and expanded. New categories, including e-cigarettes and sugary drinks, are being considered under the government’s regulatory roadmap.

For affected businesses, this means higher costs and the need to reassess pricing strategies to remain competitive.

Foreign Contractor Tax: Getting It Right from the Start

Foreign contractor tax (FCT) is a critical consideration for businesses working with overseas partners.

The applicable tax rates depend heavily on the nature of the transaction. Many service arrangements are subject to a combination of 5% VAT and 5% CIT, but this varies depending on the type of income.

For instance, royalties may be taxed at 10%, interest at around 5%, and construction services may have different rates depending on how the contract is structured.

The key risk lies in misclassification. If the nature of the transaction is not properly defined in the contract, businesses may apply incorrect tax treatment. Once payments are made abroad, correcting these errors becomes difficult.

Careful contract review before execution and payment is therefore essential.

Compliance System: Build a solid foundation from the start to avoid future problems

The difference between a stable business and one that frequently faces tax risks often lies not in the people, but in how the system is built from the beginning.

With a clear accounting system, tightly managed electronic invoices, and well-established internal control processes, most errors will be prevented before they occur. All data is well-founded, easy to verify, and easy to compare when needed.

Conversely, if you work on a case-by-case basis, small errors will gradually accumulate. When the tax authorities conduct an audit, these problems will only become apparent, often leading to significant remediation costs. Therefore, investing in a system from the start is always the most cost-effective in the long run.

Conclusion

In 2026, business taxes in Vietnam are no longer just a technical matter handled by the accounting team; it has become a core element in business management. Understanding, implementing, and controlling it effectively from the outset will help businesses reduce risks and optimize operational efficiency.

Note: Tax policies may change over time, depending on the industry and the scale of the business. Regular reviews with a professional consulting firm will help businesses stay updated on the latest regulations and minimize potential risks.
