Guide on complaint process for tax assessment decisions, tax recovery, and administrative tax violations in Vietnam. Important content for foreign businesses operating in Vietnam.
Disputes with tax authorities are common for businesses. Understanding rights and process helps protect legitimate interests and avoid unnecessary losses, especially for FDI enterprises with complex transactions.
1. Types of Tax Decisions That Can Be Complained Against
- Tax assessment decisions: tax authority self-determines tax payable when believing taxpayer declarations untrue
- Tax recovery decisions: requiring payment of overdue tax
- Administrative tax penalty decisions: penalties for incorrect declarations, late payment, evasion
- Enforcement decisions: account freezing, invoice issuance suspension
- Tax refund decisions: refusing refund or insufficient refund
2. Taxpayer Rights
Under Tax Administration Law 2019:
- Receive explanations and information on tax obligations
- Confidentiality of tax information
- Complain, sue regarding tax decisions
- Consult expert and lawyer opinions
- Request suspension of decision execution during complaint period
3. Explanation Process Before Decision Issuance
Before issuing adverse decision, tax authority must:
- Draft inspection/audit minutes
- Allow taxpayer to provide explanations
- Receive defense evidence
- Issue draft inspection conclusion
This is critical stage — maximize explanation rights to avoid post-decision complaint.
4. Tax Decision Complaint Timeline
- First-instance complaint: 30 days from decision receipt (shorter than typical administrative complaints)
- Second-instance complaint: 30 days from first-instance resolution receipt
- Administrative lawsuit: 1 year from decision receipt
This short timeline is why many businesses lose complaint rights — must act fast on adverse decisions.
5. Resolution Authority
| Decision by | First Instance | Second Instance |
|---|---|---|
| Tax Team | Sub-Department Head | Provincial Tax Director |
| Tax Sub-Department | Sub-Department Head | Provincial Tax Director |
| Provincial Tax Department | Provincial Director | General Director of Taxation |
| General Department of Taxation | General Director | Minister of Finance |
6. Tax Complaint Documentation
- Complaint petition clearly stating content, reasons, requests
- Copy of tax decision being complained against
- Copy of inspection/audit minutes (if any)
- Evidence proving correct tax declaration (invoices, contracts, books)
- Legal documents as basis
- Power of attorney for lawyer (if any)
7. Suspension of Decision Execution
Important point: when complaining, can request suspension if grounds exist that execution would cause serious and irrecoverable damage.
However tax authority does not typically auto-suspend — must have specific written request and prove grounds.
8. Key Notes
- File on time (30 days) — past deadline loses complaint rights
- Keep evidence carefully: invoices, books, contracts, bank statements
- Utilize explanation phase: many cases resolved at this stage
- Hire tax expert or lawyer: tax law is complex, mistakes can cost hundreds of millions
- File administrative lawsuit when needed: if complaint ineffective, administrative court is final option
9. Common Tax Disputes for Foreign Businesses
9.1. Transfer Pricing
Tax authority focuses heavily on transactions between Vietnamese subsidiary and foreign parent. Key issues: technical service fees, royalty rates, intra-group financing.

Foreign business may be deemed to have permanent establishment in Vietnam, subject to CIT. Disputes about whether PE exists are common.
9.3. Withholding Tax
Vietnam levies withholding tax on payments to foreign contractors. Disputes about applicable rates, treaty benefits are frequent.
9.4. VAT Refund
FDI enterprises typically have large VAT refunds. Refund decisions are often delayed or rejected, requiring complaints.
