Accounting and tax compliance in Vietnam is not optional, not light, and not forgiving.
For foreign companies, most risks do not come from tax rates—but from procedural non-compliance, incorrect filings, and weak documentation.
This guide explains how accounting and tax compliance works in Vietnam, what foreign-invested companies must do from day one, and how to avoid the most common (and costly) compliance mistakes.
Why Accounting & Tax Compliance Is Critical in Vietnam
Vietnam’s tax authorities focus heavily on:
- Documentation
- Filing accuracy
- Timeliness
- Substance over form
Penalties can apply even when:
- There is no revenue
- The company is inactive
- Errors are unintentional
📌 “We didn’t know” is not an accepted defense.
Who Must Comply With Vietnam Accounting & Tax Rules?
All entities with a Vietnam presence must comply, including:
- Wholly foreign-owned companies
- Joint ventures
- Representative Offices (limited scope)
- Branches
Compliance applies from the date of incorporation, not from first revenue.
Vietnam Accounting Framework Explained
Vietnam uses Vietnamese Accounting Standards (VAS), which differ from IFRS and US GAAP.
Key characteristics:
- Rule-based
- Documentation-heavy
- Tax-aligned accounting
- Strict invoice and record controls
📌 Financial statements prepared only under IFRS are not sufficient for statutory purposes.
Core Tax Types Foreign Companies Must Know
1️⃣ Corporate Income Tax (CIT)
- Standard rate: 20%
- Calculated on taxable profit
- Provisional payments during the year
- Final annualization required
📌 Incorrect expense deductibility is a common audit trigger.
2️⃣ Value Added Tax (VAT)
- Common rates: 0%, 5%, 10%
- Output VAT vs input VAT offset
- Monthly or quarterly filing
- Strict e-invoice requirements
📌 VAT errors are among the most penalized issues.
3️⃣ Personal Income Tax (PIT)
Applies to:
- Local employees
- Foreign employees working in Vietnam
Includes:
- Monthly withholding
- Annual finalization
- Residency determination
📌 Payroll and PIT are closely linked—errors cascade quickly.
4️⃣ Other Taxes & Obligations
Depending on activity:
- Withholding tax
- Import/export duties
- License tax
- Environmental or sector-specific fees
Mandatory Accounting & Reporting Obligations
Foreign-invested companies must:
- Maintain books in Vietnamese language
- Use VND as accounting currency
- Register accounting method
- Retain records for inspection
Filing Frequency
- Monthly or quarterly tax filings
- Annual financial statements
- Mandatory statutory audit
📌 Audits are required even with zero revenue.
Common Accounting & Tax Mistakes Foreign Companies Make
❌ No accountant after incorporation
❌ Using overseas invoices or systems
❌ Missing filings due to “no activity”
❌ Incorrect VAT treatment
❌ Poor expense documentation
❌ Late or inaccurate filings
These mistakes often result in:
- Fines
- Back taxes
- Audit findings
- Delayed profit repatriation
Representative Office vs Company: Compliance Differences
Representative Office
- No CIT or VAT on revenue
- Still subject to:
- PIT on staff
- Annual reporting
- Audit in some cases
Company (Subsidiary)
- Full tax and accounting obligations
- Monthly / quarterly filings
- Mandatory audit
📌 ROs are not compliance-free.
Accounting Outsourcing vs In-House Accounting
Outsourced Accounting
✔ Lower cost
✔ Local expertise
✔ Scalable
✔ Ideal for foreign companies
In-House Accounting
❌ Higher fixed cost
❌ Management burden
❌ Requires local oversight
📌 Most foreign SMEs choose outsourcing.
How Employer of Record (EOR) Changes Tax Exposure
If you operate via EOR only:
- No corporate tax filings
- No accounting obligations
- Payroll and PIT handled by EOR
📌 EOR is often used to delay accounting complexity until scale justifies an entity.
Compliance Checklist for Foreign Companies
✔ Registered accounting method
✔ Monthly/quarterly tax filings
✔ Proper VAT invoices
✔ Payroll & PIT compliance
✔ Annual audit completed
✔ Timely tax payments
Missing any item increases audit and penalty risk.
