And How to Avoid Costly Corrections
Most tax and compliance problems foreign companies face in Vietnam are not caused by aggressive tax planning. They stem from misunderstanding local rules, underestimating procedural requirements, or applying overseas practices that simply don’t work in Vietnam.
This article outlines the most common tax, accounting, and regulatory mistakes foreign companies make—and what smart companies do instead to stay compliant, audit-ready, and operationally flexible.
1️⃣ Assuming “No Revenue” Means “No Filing”
This is the single most common mistake.
Even if your company:
- Has no revenue
- Has not started operations
- Is temporarily inactive
👉 You are still required to file VAT, PIT, CIT (where applicable), and accounting reports.
📌 Zero activity still requires zero declarations.
Failure results in automatic penalties.
2️⃣ Treating Accounting as an Annual Task
Vietnam accounting is monthly and transactional, not annual.
Common errors:
- Recording transactions quarterly or yearly
- Reconstructing books before audit
- No monthly bank reconciliation
- Late invoice processing
📌 Annual audits do not fix poor monthly accounting—they expose it.
3️⃣ Using Overseas Accounting Standards Instead of Local Rules
Vietnam requires compliance with:
- Vietnamese Accounting Standards (VAS)
- Vietnamese chart of accounts
- Vietnamese language records
- VND accounting currency
Mistakes include:
❌ Submitting IFRS-only statements
❌ Using foreign invoicing systems
❌ English-only bookkeeping
📌 Overseas standards may be used internally—but not for statutory compliance.
4️⃣ Incorrect VAT Handling
VAT is one of the most penalized tax areas in Vietnam.
Frequent mistakes:
- Using wrong VAT rates
- Issuing invoices late
- Claiming input VAT without valid invoices
- Misclassifying export services
- Missing “zero VAT” filings
📌 VAT errors often trigger full tax audits, not just adjustments.
5️⃣ Ignoring Provisional Corporate Income Tax (CIT)
Many companies believe CIT is only due at year-end.
In reality:
- Provisional CIT must be paid quarterly
- Underpayment triggers late payment interest
- Finalization does not erase provisional underpayment penalties
📌 This catches many foreign CFOs by surprise.
6️⃣ Weak Expense Documentation
Authorities focus heavily on expense deductibility.
Common issues:
- Missing VAT invoices
- Cash payments above thresholds
- Vague service descriptions
- No proof of business purpose
📌 If an expense cannot be documented properly, it is usually disallowed.
7️⃣ Misusing Management Fees & Intercompany Charges
Management fees are high-risk in Vietnam.
Mistakes include:
- Charging fees without actual services
- No service agreements
- No deliverables or proof
- No benchmarking study
- Treating fees as profit extraction tools
📌 These fees are frequently fully disallowed during audits.
8️⃣ Ignoring Transfer Pricing Obligations
Transfer pricing compliance is procedural, not optional.
Common mistakes:
- No related-party disclosure
- Documentation prepared only after audit notice
- Copy-paste global TP reports
- Ignoring low margins or losses
📌 Even small companies can be audited if TP obligations are missed.
9️⃣ Missing Tax Filing Deadlines
Vietnam penalties are deadline-driven and automatic.
Frequent causes:
- Confusing monthly vs quarterly filings
- Relying on overseas calendars
- No local compliance tracker
- Late audit completion
📌 One missed deadline often leads to multiple penalties.
🔟 Incorrect Withholding Tax (WHT) Handling
Foreign companies often misunderstand who bears WHT.
Mistakes include:
- Assuming offshore services are not taxable
- Ignoring VAT component of WHT
- Misunderstanding gross vs net contracts
- Late WHT filings
📌 The Vietnam payer is usually liable for WHT errors.
1️⃣1️⃣ FX Transfers Without Proper Structure
Banks in Vietnam strictly enforce FX rules.
Common errors:
- Using wrong bank account (operating vs capital)
- Missing supporting documents
- Attempting repatriation before audit
- Unpaid taxes blocking transfers
📌 FX compliance failures often appear as “bank issues” but are actually regulatory violations.
1️⃣2️⃣ Choosing the Wrong Entry Model Too Early
Many problems start at market entry stage.
Examples:
- Setting up a company when only hiring is needed
- Using contractors instead of legal employment
- Misusing Representative Offices
- Delaying entity setup too long
📌 Entry structure determines long-term compliance burden.
1️⃣3️⃣ Underestimating Compliance Cost & Effort
Foreign companies often budget for:
✔ Setup cost
❌ Ongoing compliance cost
Reality includes:
- Monthly accounting
- Tax filings
- Payroll compliance
- Audits
- Inspections
- Regulatory reporting
📌 Compliance is ongoing, not one-time.
How Most Compliance Problems Actually Arise
In practice, issues usually come from:
- Inexperience with Vietnam regulations
- Lack of local advisory support
- Fragmented vendors (legal, accounting, HR not aligned)
- Reactive instead of proactive compliance
Most penalties are preventable.
How Smart Foreign Companies Avoid These Mistakes
✔ Use local accounting & tax experts
✔ Maintain a compliance calendar
✔ Do monthly bookkeeping properly
✔ Review intercompany transactions early
✔ Align tax, legal, HR, and FX planning
✔ Choose EOR when appropriate
✔ Plan exit and profit repatriation early
