Within Vietnam’s corporate tax system and regulatory framework, managing related party transactions (RPT) and defending transfer pricing arrangements represents a high-priority audit focus for provincial tax authorities. Foreign-invested enterprises (FIEs) operating in Vietnam face intense regulatory scrutiny aimed at preventing base erosion and profit shifting (BEPS) through cross-border intercompany pricing, management fee allocations, and intra-group debt financing.
Transfer pricing administration in Vietnam is governed by Decree No. 132/2020/ND-CP, enacted under Law on Tax Administration No. 38/2019/QH14 and the Law on Corporate Income Tax. Taxpayers engaging in related party transactions must adhere to OECD-aligned transfer pricing standards, monitor statutory capital and financing thresholds, and comply with strict annual documentation obligations.
1. Statutory Framework and Core Principles of Decree 132/2020/ND-CP
Decree No. 132/2020/ND-CP establishes two foundational legal principles governing all intercompany purchases, sales, leasing, asset transfers, and financial transactions:
The Arm’s Length Principle
Transactions between associated enterprises must be priced and executed under terms comparable to those agreed upon by independent parties in open-market transactions under similar economic circumstances. The taxpayer bears the statutory burden of proof to demonstrate that intercompany pricing reflects fair market value and does not reduce corporate income tax liabilities payable in Vietnam. Where pricing fails arm’s length scrutiny, tax authorities possess statutory authority to issue tax assessments under tax audit and inspection procedures.
Substance Over Form
Tax authorities prioritize commercial and economic reality over legal form. Intercompany arrangements are analyzed based on actual operational functions performed, economic assets utilized, and commercial risks assumed by each party. Cross-border intra-group management fees, headquarters recharge allocations, or technical assistance fees that fail to demonstrate direct, tangible economic benefits to the Vietnamese operating entity are disallowed as deductible expenses.
2. Criteria for Determining Related-Party Relationships Under Article 5
Under Article 5(2) of Decree No. 132/2020/ND-CP, two commercial entities are classified as related parties if they satisfy any of the following statutory thresholds:
Equity Ownership and Voting Control
- Direct or indirect ownership: One enterprise holds directly or indirectly at least 25% of the owner’s equity of the other enterprise.
- Common third-party ownership: Both enterprises have at least 25% of their equity held directly or indirectly by a common third party.
- Largest corporate shareholder: One enterprise is the largest shareholder holding directly or indirectly at least 10% of total voting shares of the other enterprise.
Loan and Guarantee Relationships (Point d Clause 2 Article 5)
A lending or borrowing relationship triggers related-party status where an entity guarantees or finances another enterprise under the following cumulative conditions:
- The borrowed funds equal at least 25% of the borrower’s equity; and
- The loan accounts for more than 50% of the borrower’s total medium- and long-term debts.
Critical Audit Alert: This statutory rule applies to any financing entity, including independent third-party commercial banks. Capital-intensive manufacturing FIEs that fund plant construction through long-term commercial bank facilities exceeding these thresholds become classified as related parties with the lender, inadvertently triggering the 30% EBITDA interest deductibility cap.
Operational Management and Governance Control
- One enterprise appoints or has the power to appoint more than 50% of the board of directors or key executive officers of the other enterprise.
- Both enterprises have more than 50% of their board members appointed by a common third party.
- One enterprise controls the strategic business operations or pricing policies of the other through exclusive commercial contracts or licensing agreements.
3. The 30% EBITDA Net Interest Deductibility Cap Under Article 16
Article 16(3) of Decree No. 132/2020/ND-CP imposes an aggregate cap on deductible loan interest expenses for enterprises engaging in related party transactions:
Net Interest Expense Formula and Deductibility Limit
Total deductible loan interest incurred during the fiscal year (encompassing both related-party debt and third-party bank borrowings) is capped at 30% of adjusted EBITDA:
Five-Year Carryforward Mechanism for Excess Interest
Non-deductible net interest expense exceeding the 30% EBITDA ceiling may be carried forward to subsequent tax years:
- The carryforward period is limited to 5 consecutive tax years, starting from the year immediately following the year in which the excess interest was incurred.
- Carried-forward interest is deductible in subsequent years provided that the total net interest expense in that future year remains below the 30% EBITDA threshold.
4. Safe Harbor Exemptions from Transfer Pricing Documentation Under Article 19
Article 19 of Decree No. 132/2020/ND-CP exempts qualifying taxpayers from the obligation to compile detailed Transfer Pricing Documentation (Local File and Master File):
| Exemption Category | Statutory Criteria | Specific Operational Conditions | Compliance Requirement |
|---|---|---|---|
| Small-Scale Operations | Revenue < VND 50 billion & total RPT < VND 30 billion | Evaluated within the annual fiscal tax year | Form 01 filing remains mandatory |
| Concluded APA | No monetary revenue ceiling | Formal Advance Pricing Agreement signed with tax authorities | Submit Annual APA Compliance Report |
| Simple Functions | Revenue < VND 200 billion without intangibles | Net profit margin (EBIT/Revenue) meets: Distribution ≥ 5%, Manufacturing ≥ 10%, Processing ≥ 15% | Form 01 filing remains mandatory |
| Purely Domestic RPT | All associated parties are taxpayers in Vietnam | Parties share identical CIT rates and neither enjoys tax incentives | Form 01 filing remains mandatory |
Important Compliance Reminder: Being exempt from preparing the Local File and Master File does not exempt the taxpayer from declaration obligations. Taxpayers must still submit Form 01 alongside their annual CIT return.
5. Mandatory Annual Filing of Form 01 and Three-Tiered TP Dossiers
Taxpayers with related party transactions face structured compliance obligations under Article 18 of Decree No. 132/2020/ND-CP:
Mandatory Annual Disclosure: Form 01
Every enterprise with related party transactions must complete and submit Form 01 (Information on Related-Party Relationships and Transactions) electronically together with the annual CIT Finalization Return (Form No. 03/TNDN) within 90 days from the end of the fiscal year.
On Form 01, the taxpayer must formally declare whether it qualifies for documentation exemptions or certify that required transfer pricing dossiers have been completed.
Three-Tiered Transfer Pricing Documentation Package
Enterprises not qualifying for statutory exemptions must maintain a three-tiered documentation structure:
- Local File (Phụ lục II): Detailed entity-level documentation containing functional, asset, and risk (FAR) analyses, local value chain breakdowns, and economic benchmarking studies applying approved transfer pricing methods (CUP, RPM, Cost Plus, TNMM, or Profit Split).
- Master File (Phụ lục III): Global corporate group overview detailing global business operations, supply chains, intellectual property policies, and intra-group financing structures.
- Country-by-Country Report (CbCR - Phụ lục IV): Required for multinational enterprise (MNE) groups with consolidated global revenue exceeding VND 18,000 billion (or matching statutory thresholds in the ultimate parent entity’s jurisdiction).
Documentation Timeline and Presentation Deadlines
Transfer pricing documentation must be finalized prior to the annual CIT finalization submission deadline. Upon receiving a formal written audit request from tax inspection teams, the enterprise must present the complete documentation within 30 working days (or 15 working days during pre-audit consultation stages).
6. Audit Triggers, Tax Assessment Mechanisms, and Statutory Penalties
Tax authorities utilize automated risk-scoring algorithms and proprietary commercial benchmark databases to select transfer pricing audit targets:
Primary Transfer Pricing Audit Triggers
- Consecutive operating losses spanning multiple years alongside expanding revenue and operational capacity.
- Operating profit margins significantly below industry benchmark medians for comparable independent companies.
- Disproportionate royalty payments, head-office management charges, or intercompany interest expenses.
- Procuring production machinery or raw materials from foreign affiliates at prices significantly exceeding independent market rates.
Statutory Enforcement and Penalty Exposure
Failure to submit Form 01, late presentation of transfer pricing dossiers, or reliance on flawed benchmarking data triggers severe administrative enforcement:
- Direct Tax Assessment (Articles 13 & 20 Decree 132/2020/ND-CP): Tax inspectors reject the enterprise’s accounting records and independently select comparable data to assess profit margins and taxable income.
- Administrative Penalties (Decree 125/2020/ND-CP): A 20% penalty is assessed on underdeclared tax liabilities, alongside fines of VND 8 million to 15 million for failing to submit Form 01.
- Late-Payment Interest (Law on Tax Administration 38/2019/QH14): Statutory interest of 0.03% per day is charged on retroactive tax assessments, accumulating substantial liabilities over multi-year audit cycles.
To safeguard corporate standing and prevent punitive assessments, foreign investors should review profit margins annually and maintain robust Local and Master Files prior to annual filings.
