Accounting Services in Vietnam (2026): Cost Guide, Tax Reporting & Outsourcing Solutions for FDI Enterprises

Nowadays, professional accounting has become an essential solution for both domestic companies and those looking to open an FDI Company in Vietnam, especially as tax and accounting systems become increasingly stringent and complex. In practice, managing accounting in-house can expose businesses to significant risks, such as tax declaration errors, late financial reporting, or administrative penalties for non-compliance.

In Vietnam, businesses must fulfil a wide range of accounting obligations, including bookkeeping, periodic tax declarations (VAT, CIT, PIT), financial statement preparation, and document archiving under the Vietnamese law. This is challenging for newly established enterprises and foreign investors unfamiliar with the Vietnamese legal environment.

Consequently, more businesses are turning to professional Tax Advisory Services to ensure legal compliance, mitigate risks, and optimise operational costs. Statistics show that enterprises can save between 30% and 50% by outsourcing accounting compared to maintaining an in-house department. Moreover, over 70% of startups and FDI firms choose to outsource their financial management from their very first years of operation to:

• Ensure full legal compliance with Vietnamese standards.
• Minimise risks of tax arrears and administrative sanctions.
• Optimise operational costs and internal resources.

With 19 years of expertise in legal, accounting, and tax reporting services, Viet An Law has partnered with thousands of domestic and FDI enterprises. Our accounting solutions are designed for every business model, with service fees starting from approximately 500,000 VND/month, helping businesses optimise operations from the outset.

Comparison Table: In-house accounting vs. outsourced accounting & tax services

For newly established Vietnamese companies and FDI enterprises, outsourced accounting and tax services not only help with legal compliance but are also an optimal solution for reducing costs, mitigating risks, and operating efficiently right from the start.

Timeline of corporate tax obligations in Vietnam (2026)

Important notes:

• New enterprises typically file taxes quarterly, but may switch to monthly as they grow.
• Financial statements must be submitted within 90 days of the end of the fiscal year.
• FDI enterprises are required to have their financial statements audited before submission.

Failure to meet tax obligations on time can result in penalties, tax arrears, or high-risk assessments from tax authorities. Therefore, many Vietnamese and FDI enterprises choose professional accounting and tax services to ensure timely compliance and minimise risks.

Risks of non-compliance with accounting and tax regulations in Vietnam

Failure to properly fulfil accounting and tax obligations in Vietnam can expose both domestic and FDI enterprises to serious risks, especially during the initial establishment or expansion phases.

Common risks include:

• Administrative penalties ranging from 5 million to over 100 million VND, depending on the severity of the violation
• Tax arrears and late payment penalties
• Ineligibility for VAT refund
• Discrepancies in financial reporting, impacting business operations and fundraising
• Damage to the company’s reputation in cooperation with partners and authorities

In fact, many Vietnamese enterprises and foreign investors have encountered difficulties due to a lack of understanding of accounting and tax regulations in Vietnam, especially regarding periodic declaration obligations and document archiving.

Therefore, more and more enterprises are choosing to use professional accounting services from the outset as a safe, legal-compliant solution to minimise risks and optimise operational efficiency.

Service fees for accounting and tax reporting services in Vietnam in 2026

The cost of accounting services in Vietnam depends on the size, industry, and volume of documentation of the enterprise. Below are some reference prices:

Important note:

• Costs may vary depending on the number of invoices, personnel, and the complexity of business operations.
• FDI enterprises often require additional services such as management reporting, auditing, and investment compliance.
• Some providers offer basic packages starting from around VND 500,000/month for very small or low-volume enterprises.

Compared to maintaining an in-house accounting department (including payroll, insurance, and administrative expenses), enterprises can save 30%-50% on costs by using tax accounting services, while minimising legal risks and optimising operational efficiency.

Common accounting mistakes made by enterprises in Vietnam

In practice, many enterprises, especially startups and those looking to open an FDI company in Vietnam, often encounter accounting errors due to a lack of understanding of local legal regulations. These situations not only lead to legal risks but also cause financial damage and affect long-term business operations.

Here are the most common mistakes:

Failure to file tax declarations on time

Many enterprises are unaware of the tax filing schedule (VAT, CIT, PIT), leading to late filing, administrative penalties, and even late-payment fees.

Late preparation and submission of financial statements

• Enterprises in Vietnam are obligated to prepare and submit annual financial reports. Late submission or errors in financial reports may result in:
• Administrative penalties
• High tax risk assessment
• Difficulties in obtaining loans, conducting audits, and securing business partnerships.

Failure to conduct financial audits (for FDI companies)

• For enterprises with foreign investment, annual financial statements are usually required to be audited by an independent auditing firm. However, many businesses fail to comply or incorrectly comply with this regulation, leading to:
• Financial statements are not being accepted
• Impact on reporting to regulatory authorities
• Legal risks and impact on the parent company abroad

Inadequate valid document storage

The lack of invoices, supporting documents, or improper storage may result in enterprises being denied tax deductions or having expenses disallowed during tax settlement.

Insufficient understanding of the legal system

Due to a desire to save costs, many enterprises handle their own accounting without professional expertise, leading to errors in recording revenue and expenses and filing taxes.

Failure to update current tax regulations

The legal system regarding taxation and accounting in Vietnam is constantly changing. Without constant updates, enterprises can easily misapply regulations and face penalties.

Confusion between Vietnamese and International Accounting Standards

For FDI enterprises, incorrect application of VAS and IFRS can lead to inaccurate financial reporting and affect internal management or parent company reporting.

Lack of regular internal reviews of the accounting system

• Many enterprises address accounting issues only when problems arise rather than conducting regular audits, leading to accumulated errors that are difficult to correct later.
• In fact, these mistakes are the main reason many enterprises incur tax arrears or penalties during operations.

Therefore, establishing an accounting system from the outset or using professional accounting services helps enterprises ensure legal compliance, minimise risks, and optimise long-term costs.
