Vietnam continues to attract foreign investors and international businesses, but entering the market without a clear understanding of local regulations can turn an attractive business opportunity into a costly legal problem. From offshore investment structures and tax obligations to employment, data protection, and contractual risks, businesses need to identify the five costly legal issues when doing business in Vietnam before they become disputes, penalties, or unexpected operating costs.
Vietnam’s regulatory environment has undergone significant changes in 2025 and 2026. The new Law on Investment No. 143/2025/QH15 took effect on March 1, 2026, while new tax, tax administration, labor, and personal data regulations have also changed the compliance landscape.
For foreign investors in particular, understanding the legal framework before establishing or expanding operations is often much less expensive than correcting a non-compliant structure later. The following are five costly legal issues when doing business in Vietnam that companies should address from the beginning.
Market Entry and Investment Structure
One of the most important legal decisions is determining how a business should legally enter and operate in Vietnam. Foreign investors may establish an enterprise, contribute capital to an existing Vietnamese company, acquire shares or capital contributions, establish certain forms of commercial presence, or use other structures depending on the business model and applicable regulations.
The new Law on Investment No. 143/2025/QH15 has been effective since March 1, 2026, making the current investment framework particularly important for companies planning market entry or restructuring.
A common mistake is to focus primarily on obtaining an investment or enterprise registration certificate while overlooking whether the proposed business activities, ownership structure, licensing requirements, or investment conditions are legally compatible.
For example, a foreign investor may assume that registering a company automatically allows it to conduct every activity described in its business plan. In practice, certain sectors can be subject to market-access conditions, specialized licenses, foreign ownership restrictions, or additional operational requirements.
These are among the most important legal risks that can be expensive for businesses in Vietnam because a structurally incorrect setup can affect licensing, financing, tax treatment, contracts, and even the ability to lawfully conduct particular activities.
A careful market-entry review should therefore consider:
- whether the intended business activities are open to foreign investment;
- whether specific market-access conditions apply;
- whether the proposed ownership and capital structure is appropriate;
- whether additional licenses or approvals will be required; and
- whether the investment structure remains suitable as the business expands.
Spending more time on the structure at the beginning can prevent substantial restructuring costs later. This is one of the most practical ways of avoiding costly legal mistakes in Vietnam business operations.

Tax, Invoicing, and Financial Compliance
Tax compliance is another area where apparently minor administrative errors can develop into significant financial exposure. Vietnam’s tax framework has continued to evolve, including the Tax Administration Law No. 108/2025/QH15, which took effect on July 1, 2026, and amendments to major tax laws introduced in 2026.
Businesses need to look beyond the headline corporate income tax rate. The legal and financial consequences of operating in Vietnam can involve corporate income tax, value-added tax, withholding obligations, transfer pricing, invoices, accounting documentation, and tax administration procedures.
The amended VAT framework also took effect from January 1, 2026, while Law No. 09/2026/QH16 further amended the laws on personal income tax, VAT, corporate income tax, and special consumption tax.
This means that companies cannot safely rely on tax procedures or internal accounting practices that were designed several years ago. A business model that was compliant when established may require adjustment after regulatory changes, particularly where the company has cross-border transactions or related-party arrangements.
For foreign businesses, tax exposure can become especially complicated when Vietnam operations interact with a foreign parent company. Payments for services, royalties, technology, management support, financing, or other cross-border arrangements should be reviewed from both contractual and tax perspectives.
Among the most serious legal risks that can be expensive for businesses in Vietnam are therefore not necessarily dramatic violations. They can arise from incorrect documentation, inconsistent invoices, inappropriate contractual characterization, or failure to update internal tax procedures after regulatory changes.
Employment and Workforce Compliance
Employment law is another area where companies can underestimate their exposure. Employment-related obligations extend well beyond signing an employment contract and paying salaries.
Vietnam’s minimum wage framework was updated under Decree No. 293/2025/NĐ-CP, effective January 1, 2026. The monthly minimum wages now range from VND 3.7 million to VND 5.31 million depending on the applicable region, with corresponding hourly minimum wages.
Companies also need to consider working hours, overtime, social insurance, employee benefits, internal labor regulations, disciplinary procedures, termination, and workplace policies. For businesses employing foreign nationals, immigration and work-permit compliance creates another layer of legal responsibility.
The financial consequences of employment non-compliance can extend beyond administrative penalties. A poorly drafted employment contract can make termination more difficult. An improperly implemented disciplinary process can weaken the employer’s position in a dispute. Failure to correctly manage social insurance or salary-related obligations can create accumulated liabilities across a large workforce.
These are critical legal pitfalls for companies operating in Vietnam because employment problems often emerge only after the employment relationship has deteriorated. At that stage, correcting the original compliance failure can be considerably more difficult.
Businesses should therefore periodically review employment documentation rather than treating labor compliance as a one-time task. This is particularly important after changes in minimum wages, social insurance requirements, internal policies, or workforce structure.
Personal Data, Intellectual Property, and Digital Operations
Digital businesses face another increasingly important area of legal exposure: personal data and intellectual property.
Vietnam’s Law on Personal Data Protection No. 91/2025/QH15 took effect on January 1, 2026. This places personal-data compliance firmly within the current legal framework for businesses collecting, storing, using, transferring, or otherwise processing personal data.
The implementing framework also provides certain exemptions or simplified treatment for particular categories of smaller businesses, although important exceptions apply, including businesses providing personal-data processing services, directly processing sensitive personal data, or reaching specified data-subject thresholds.
For companies operating websites, applications, e-commerce platforms, HR systems, customer databases, or digital marketing operations, personal data should therefore be treated as a legal compliance issue rather than merely an IT-security concern.
Intellectual property presents a similar problem. Businesses entering Vietnam may bring trademarks, software, designs, technical know-how, copyrighted materials, or other intangible assets that have substantial commercial value. Failing to properly protect ownership or define rights in employment, licensing, distribution, and technology agreements can leave valuable assets exposed.
These are among the top legal issues foreign businesses face in Vietnam because the underlying assets may be developed outside Vietnam while being commercially exploited inside the country. A global IP portfolio does not automatically eliminate the need to assess Vietnamese protection and enforcement mechanisms.
Companies should therefore review both data and IP ownership before launching products or services in Vietnam. Doing so can help reduce legal risks that can be expensive for businesses in Vietnam while also protecting the commercial value of digital operations.
Contracts, Licenses, and Regulatory Commitments
The fifth major area concerns contracts and the legal commitments that businesses make during ordinary operations.
A company may have a valid offshore investment structure and reasonable tax planning but still suffer significant losses because its commercial contracts do not adequately allocate risk. Distribution agreements, supply contracts, service agreements, technology licenses, employment arrangements, leases, and cooperation agreements can all create liabilities that are difficult to identify after a dispute arises.
Common contractual weaknesses include unclear payment conditions, inadequate termination rights, poorly drafted indemnities, ambiguous product specifications, insufficient confidentiality provisions, and dispute-resolution clauses that do not reflect the commercial relationship.
Licensing should also be considered as part of contract and operational planning. A company should not assume that a general enterprise registration permits every operational activity. Depending on the sector, additional approvals, certificates, or specialized compliance measures may be required.
This is where five costly legal issues when doing business in Vietnam often overlap. A poorly structured investment can create licensing problems; an unclear contract can create tax or payment disputes; weak employment documentation can create litigation exposure; and inadequate IP provisions can result in loss of valuable business assets.
The most effective approach is therefore not to review each legal issue in isolation. Companies should assess the interaction between corporate structure, licenses, contracts, tax, employment, IP, and data protection before launching significant operations.
How Businesses Can Reduce Their Legal Exposure in Vietnam
The cost of legal compliance should be viewed as part of business planning rather than as an expense that arises only after a problem occurs.
For companies entering Vietnam or expanding existing operations, a practical legal review should focus on five areas:
- Market entry: Confirm the appropriate investment structure, ownership arrangements, business activities, and licensing requirements.
- Tax and finance: Review tax registration, invoicing, accounting, cross-border payments, and related-party transactions.
- Employment: Check employment contracts, wages, social insurance, internal labor regulations, disciplinary procedures, and foreign-worker compliance.
- Data and IP: Identify personal-data processing activities and confirm ownership and protection of trademarks, software, technology, and other intellectual assets.
- Contracts and operations: Review key commercial agreements, licenses, risk allocation, termination rights, and dispute-resolution mechanisms.
Avoiding costly legal mistakes in Vietnam business operations does not necessarily require making every business decision more complicated. The more effective strategy is to identify the areas where legal requirements can materially affect the company’s business model and address them before implementation.
For international companies, local legal review should also be integrated into broader compliance systems rather than conducted only when a transaction, dispute, or regulatory inspection occurs. This can make legal compliance more predictable and reduce the risk that a seemingly small issue develops into a major financial liability.
Ultimately, the five costly legal issues when doing business in Vietnam are not limited to isolated regulatory violations. They are interconnected risks that can affect a company’s ability to enter the market, hire employees, manage taxes, protect valuable assets, and enforce commercial rights.
FAQ

The five major areas are offshore investment and market-entry structure, tax and financial compliance, employment law, personal data and intellectual property, and commercial contracts and licensing. The financial impact can vary significantly depending on the company’s industry, size, ownership structure, and activities.
2. Why can legal risks that can be expensive for businesses in Vietnam arise even when a company is properly registered?
Enterprise registration does not necessarily mean that every aspect of the company’s operations is compliant. Businesses may still need sector-specific licenses, tax compliance, employment procedures, data-protection measures, IP protection, and properly structured contracts.
3. What are the critical legal pitfalls for companies operating in Vietnam?
Common pitfalls include selecting an unsuitable investment structure, failing to update tax procedures, using inadequate employment documentation, overlooking personal-data obligations, failing to protect IP assets, and signing contracts without appropriate risk-allocation provisions.
4. How can companies focus on avoiding costly legal mistakes in Vietnam business operations?
Companies should conduct legal due diligence before market entry, periodically review regulatory changes, maintain appropriate corporate and tax records, update employment and data-protection policies, and have material commercial contracts reviewed before signing. Preventive legal review is generally more effective than trying to resolve a compliance problem after it has already caused financial damage.
