What is a tax accounting service company?

A professional accounting and tax service company is an entity that acts on behalf of a business to perform accounting and tax tasks in accordance with the law. The scope of work typically includes document verification, recording economic transactions, preparing periodic tax reports, preparing financial statements, and advising on how to handle arising issues.

According to Accounting Law No. 88/2015/QH13Accounting work must ensure honesty, completeness, timeliness, and adherence to accounting principles. Therefore, accounting services go beyond simply data entry and also involve controlling the quality of financial information.

In Vietnam, businesses can hire qualified accounting service providers to perform part or all of their accounting tasks. This is particularly suitable for small businesses, startups, or businesses that need to standardize their financial systems.

Why do businesses need professional tax accounting services?

Many business owners focus solely on paying taxes on time but fail to fully assess the risks arising from documentation, invoices, and accounting practices. A small error in recording expenses can directly impact tax obligations.

A professional tax accounting service company offers many practical benefits:

• Control incoming and outgoing documents in accordance with regulations.
• Minimize errors when preparing VAT, corporate income tax, and personal income tax returns.
• Standardizing financial reports for the benefit of banks, investors, or auditors.
• Assisting businesses in resolving outstanding issues in their accounting records.

Based on MAN – Master Accountant Network's practical consulting experience, many businesses face risks not from intentional wrongdoing, but from a lack of proper document verification procedures and a misunderstanding of the impact of new tax policies.

Which businesses should use tax accounting services?

According to Article 2 of the 2015 Accounting Law, the entities subject to the accounting system include state agencies, public service units, enterprises of all economic sectors, branches and representative offices of foreign enterprises, cooperatives, and large-scale business households. Among these, the groups that most frequently require accounting and tax services include:

• The newly established business does not yet have a stable internal accounting department.
• FDI businesses need to have a thorough understanding of both Vietnamese tax laws and the reporting standards of their parent company.
• Household businesses with revenue exceeding the tax threshold have now been adjusted to 1 billion VND per year according to Decree 141/2026/ND-CP issued on April 29, 2026.
• Businesses may have complex transactions such as transfer pricing, internal corporate restructuring, or be affected by foreign contractor tax.

For household businesses, the constantly changing taxable revenue threshold in a short period of time also demonstrates that tax laws are evolving faster than the ability of most household business owners to keep up with the changes.

Frequently Asked Questions about Tax Accounting Services Companies

How is hiring a tax accounting firm different from hiring a freelance accountant?

Accounting service companies must have a certificate of eligibility to conduct accounting services and bear joint legal liability under the contract, while freelance accountants usually do not have the legal standing to assume this responsibility.

How can I verify if a company is qualified to practice tax accounting?

The Certificate of Eligibility for Accounting Services can be looked up on the Ministry of Finance's portal, and the Tax Agent Professional Certificate can be found on the General Department of Taxation's system.

When should a business switch tax accounting service providers?

Consider changing your current unit if it fails to keep up with new legal regulations, frequently submits reports late, or cannot provide clear explanations during tax audits.

Can hiring a tax accounting firm completely replace an in-house accountant?

Depending on the size and management needs of the business, outsourcing accounting services can handle most accounting tasks for small businesses or those that don't yet require a dedicated accounting department. For larger businesses, tax accounting services are often used as a solution to assist with audits, provide expert advice, or handle complex transactions.

Do tax accounting service companies provide support when businesses are subject to tax audits or settlements?

Yes, MAN assists businesses with reviewing records, explaining data, preparing documents, and advising on how to handle situations when dealing with tax authorities.
