Finding a Tax Services Company in Ho Chi Minh City That Handles Everything From A to Z

Tax services in Ho Chi Minh City that genuinely cover “A to Z” for a foreign-owned company include the whole tax life of the entity: setting up tax accounts after licensing, monthly or quarterly returns, the annual finalization, letters and examinations from the tax authority, and the tax steps when the company changes or closes. Many providers only file returns. The way to tell the difference is to ask who does each task, by when, and who answers the tax office when something is questioned.

This guide sets out what full-service tax services in Ho Chi Minh City should include, what changed in Vietnam’s tax rules in 2026, and the questions worth asking before you sign.

What “A to Z” tax services in Ho Chi Minh City should cover

The table below follows the order in which obligations arise for a newly licensed foreign-owned company. A provider of tax services in Ho Chi Minh City does not need to perform every item itself, but it should be able to tell you who does.

Stage	Tasks	Who usually acts
After the Enterprise Registration Certificate	Confirm the tax code (the enterprise code), set up the e-tax account and digital signature, register to use e-invoices, notify bank accounts	Provider prepares; legal representative approves
Every month or quarter	VAT return, PIT withholding return, foreign contractor tax when paying overseas suppliers, provisional CIT	Provider prepares and submits; company supplies invoices, contracts and payroll data
Year-end	CIT finalization, PIT finalization (for employees who authorize the employer), statutory financial statements and audit coordination	Provider and chief accountant; auditor for the audit opinion
When the tax office writes	Requests for explanation, tax examinations, refund dossiers	Provider drafts and attends where authorized; company signs
When the company changes or closes	Address or capital changes, tax closure before dissolution	Provider coordinates with the legal team

Under Clause 1, Article 12 of the Law on Tax Administration No. 108/2025/QH15, passed by the National Assembly and effective from 1 July 2026, the taxpayer must declare accurately, truthfully and completely, and calculate the tax payable itself. Outsourcing the work does not move that obligation away from your company, which is why the scope matters.

Setup After Business Registration

Under Clause 2, Article 11 of Law on Tax Administration No. 108/2025/QH15, adopted on December 10, 2025 and effective from July 1, 2026, an enterprise’s tax identification number is its enterprise identification number issued in accordance with applicable legislation.

Although tax registration is generally integrated with business registration, newly established companies must still organize their tax compliance arrangements. These include establishing access to electronic tax services, managing digital signatures securely, and completing the applicable electronic invoice registration procedures before issuing invoices.

Electronic invoicing requirements are governed by Government Decree No. 254/2026/ND-CP, dated June 30, 2026 and effective from July 1, 2026. Companies should also review their banking and tax registration information to determine whether any updates or notifications are required in their particular circumstances.

Importantly, Clause 7, Article 10 of National Assembly Resolution No. 198/2025/QH15, dated May 17, 2025, discontinued the collection and payment of the business licence fee (lệ phí môn bài) from January 1, 2026. Accordingly, a newly established company should not be charged this fee for 2026 onwards. An onboarding checklist that still includes it as a current recurring obligation should be reviewed and updated.

Recurring Tax Filings

Vietnam’s tax filing requirements are governed by Law on Tax Administration No. 108/2025/QH15 and its implementing regulations, particularly Government Decree No. 252/2026/ND-CP, dated June 30, 2026 and effective from July 1, 2026.

Under Article 10 of Decree No. 252/2026/ND-CP, the general filing deadlines are:

• Monthly tax returns: No later than the 20th day of the following month.
• Quarterly tax returns: No later than the last day of the first month of the following quarter.
• Annual tax finalization returns: Generally, no later than the last day of the third month following the end of the relevant tax finalization period.

These general deadlines are subject to applicable exceptions and the requirements of individual taxes.

For corporate income tax (CIT), businesses should separately confirm their provisional tax payment obligations and the applicable payment schedule, rather than assuming that the deadlines for periodic tax returns also govern provisional CIT payments.

Before engaging an accounting or tax service provider, request a company-specific tax compliance calendar identifying the applicable monthly or quarterly VAT filing period, CIT provisional payment obligations, annual tax finalization deadlines, responsible personnel, and required supporting documents.

A dated compliance calendar allows businesses to distinguish statutory filing obligations from internal preparation deadlines and provides a clearer basis for monitoring tax compliance throughout the year.

Year-end

The annual CIT and PIT finalization depend on books that are closed correctly. If your accounting and tax are handled by different firms, agree in writing who prepares the year-end adjustments and who signs off before the finalization is filed.

When the tax authority asks questions

This is where “A to Z” is most often missing. A request for explanation or a tax examination needs someone who knows your file, can prepare the explanation and can attend meetings where the law allows a representative. Ask whether that is included or charged separately.

What changed in 2026 that your provider should already apply

Several instruments took effect in 2026.A provider of tax services in Ho Chi Minh City that cannot explain how each change affects your company is unlikely to be covering the full scope.

• Law on Tax Administration No. 108/2025/QH15, effective 1 July 2026, replacing Law No. 38/2019/QH14. According to the Government’s summary of the law, tax inspections are no longer organized by the tax authority; oversight now runs through risk-based tax examinations and data analysis (xaydungchinhsach.chinhphu.vn).
• Business licence fee abolished from 1 January 2026 under Resolution No. 198/2025/QH15.
• Law on Personal Income Tax No. 109/2025/QH15, effective 1 July 2026, which changes how salary income is taxed and therefore how payroll withholding is set up.
• Circular No. 99/2025/TT-BTC, issued by the Ministry of Finance on October 27, 2025, provides guidance on Vietnam’s enterprise accounting regime. Under Clause 1, Article 31, the Circular takes effect on January 1, 2026, and applies to financial years beginning on or after that date. It replaces Circular No. 200/2014/TT-BTC and certain related amendments, subject to the exceptions specified in Article 31. Although accounting records provide essential information for tax compliance, corporate tax liabilities must be determined in accordance with applicable tax laws, rather than accounting regulations alone. (Official Circular | Ministry of Finance Guidance)
• Law on Corporate Income Tax No. 67/2025/QH15, adopted by the National Assembly on June 14, 2025, took effect on October 1, 2025. Under Clause 1, Article 19, the Law applies from the 2025 corporate income tax period, not the 2026 tax period. Businesses should also consider applicable transitional provisions and subsequent amendments when determining their corporate income tax obligations. (Official Law)

Tax agent, accounting service, or both?

These are different services, and a small foreign-owned company often needs both. A tax agent handles tax procedures on the company’s behalf: registration, filing, and dealing with the tax authority within the scope the law allows. An accounting service keeps the books, prepares vouchers and financial statements, and in some cases provides the chief accountant role. The tax return is only as good as the books behind it.

If you engage one firm for both, the hand-off between bookkeeping and tax filing happens inside one team. If you split them, write down who is responsible for reconciling the books with each return. If you are weighing this choice, see how our tax agent services in Ho Chi Minh City are scoped.

10 questions to ask before choosing tax services in Ho Chi Minh City

1. Which of the stages in the table above are included, and which are charged separately?
2. Who prepares and who submits each return, and under whose digital signature?
3. Can you give us a dated filing calendar for our company for the next 12 months?
4. What will we receive every month (reconciliations, tax position, list of upcoming deadlines)?
5. Who replies when the tax office sends a letter, and how quickly will you tell us?
6. Will the e-tax account and digital signature remain under our control?
7. Who reviews your work before filing, and what is their qualification?
8. What happens if a return is filed late or incorrectly because of your error?
9. In which language will we receive reports, and who is our day-to-day contact?
10. If we change provider, what will you hand over and how long will it take?

Warning signs that “full service” is not full

When comparing tax services in Ho Chi Minh City, the most common gap is a provider that files returns but does not reconcile them with the books, so differences only surface at year-end or during an examination. Another is silence: no calendar, no monthly report and no warning about changes such as the new tax administration law. A third is control of access, where the provider holds the only copy of the digital signature or the tax portal password. None of these is visible from a price quotation, which is why the questions above matter more than the fee.

Who is responsible when a filing goes wrong

Who Is Responsible When a Tax Filing Goes Wrong?

The company remains responsible for its tax obligations even when it engages an external tax service provider. Under Law on Tax Administration No. 108/2025/QH15, dated December 10, 2025 and effective from July 1, 2026, taxpayers are required to submit accurate, complete and truthful tax declarations, meet applicable filing deadlines, and pay their tax liabilities on time.

Under Point (a), Clause 2, Article 16 of the Law, late-payment interest is generally calculated at 0.03% per day on the outstanding tax amount in the circumstances specified by law. The applicable calculation period, exceptions and other treatments must be assessed under the relevant regulations.

Late submission of a tax return and late payment of tax are separate compliance issues and should not be treated as interchangeable.

Where an external service provider prepares or submits tax filings, the allocation of responsibilities between the company and the provider should be clearly documented in the service agreement. Before signing, businesses should confirm the agreed scope of work, filing and approval responsibilities, procedures for correcting errors, liability for losses arising from the provider’s contractual breaches, and any applicable professional indemnity insurance.

Businesses should also establish regular tax compliance reviews and monitor changes to applicable regulations, particularly in light of the legislative developments introduced during 2025 and 2026.
