Vietnam Value Added Tax (VAT) applies across four statutory rate brackets: 0% (exported goods, qualifying cross-border services, international transport), 5% (essential commodities, clean water, medical supplies, education, agricultural inputs), 8% (temporary 2% reduction from standard 10% extending through December 31, 2026 under Resolution 204/2025/QH15), and 10% (standard statutory rate). VAT registration is a mandatory statutory obligation upon corporate licensing, applying uniformly without any turnover de minimis threshold.
A critical operational risk in corporate VAT management centers on banking payment vouchers: every procurement transaction with an invoice value of VND 5 million or more (inclusive of VAT) must be executed via non-cash banking methods. Non-compliant enterprises lose the right to credit input VAT across the entire value of the affected transaction.
Governed by Law on VAT No. 48/2024/QH15 and Decree 181/2025/ND-CP. When creditable input VAT exceeds output VAT, the surplus carries forward to offset future liabilities or qualifies for direct cash refund under statutory channels.
Two Statutory VAT Calculation Methods
Vietnamese tax legislation establishes two distinct calculation methodologies for determining VAT obligations:
| Calculation Method | Statutory Computation Formula | Target Taxpayer Scope |
|---|---|---|
| Credit-Invoice Method (Deduction Method) | Net VAT Payable = Output VAT − Creditable Input VAT | Enterprises with full accounting records, invoices, and vouchers and annual revenue of VND 1 billion or more, or that register voluntarily (Article 11 of the VAT Law; Article 21 of Decree 181). Most FDI enterprises fall in this group. |
| Direct Cash Method (Deemed Revenue %) | Net VAT Payable = Taxable Revenue × Statutory Industry Ratio % | Household businesses, individual businesses, and enterprises with annual revenue below VND 1 billion that have not registered for the credit method (Article 12 of the VAT Law). |
Most foreign-invested enterprises use the credit-invoice deduction method, because annual revenue of VND 1 billion or more requires it and newly established enterprises with investment projects or fixed-asset purchases may register for it voluntarily.
VAT Registration: Tax Code Issued With the ERC
Enterprises receive their tax code together with the Enterprise Registration Certificate (ERC) through the interconnected one-stop mechanism, so no separate tax registration filing is needed (Article 6(1)-(2) of Decree 252/2026/ND-CP), and no initial grace period is permitted.
The onboarding process operates across three interconnected technical subsystems: configuring authorized electronic invoicing, registering an electronic tax portal account with the Department of Taxation at dichvucong.gdt.gov.vn, and activating the tax portal profile for the enterprise tax identification number (TIN). Input VAT on pre-incorporation purchases made for setting up the company is creditable only when the founders authorized the payer in writing, the invoice names the authorized person, and non-cash payment supports every invoice of VND 5 million or more (Article 24 of Decree 181).
Mandatory infrastructure and documentation requirements:
- Department of Taxation E-Tax Portal Account: Enables electronic tax declarations (VAT, CIT, PIT withholding) and treasury tax payments, authenticated via corporate digital signatures or the legal representative VNeID electronic identification.
- Digital Signature (USB Token or Cloud HSM): Procured from a Ministry-licensed certification authority to authenticate electronic returns, administrative documents, and commercial e-invoices.
- E-Invoicing Software System: Deployed through an authorized solution provider and certified T-VAN transmission intermediary in compliance with Decree 254/2026/ND-CP and Circular 91/2026/TT-BTC, which replaced Decree 123/2020/ND-CP from July 1, 2026.
- Commercial Bank Accounts: Opened at licensed commercial banks operating in Vietnam and officially registered with the municipal tax department to link electronic tax payment capabilities.
Pre-Licensing Procurement Warning: Enterprises should not purchase machinery, capital equipment, or facility improvements before incorporation without a written founder authorization. Premature procurement outside such an authorization results in loss of input VAT credits from the company establishment phase.

Statutory VAT Rate Structure
The prevailing VAT tariff structure categorizes goods and services into four statutory rate tiers alongside exempt supplies:
| VAT Rate Tier | Statutory Scope | Typical Industry Scenarios |
|---|---|---|
| 0% | Exported goods, qualifying cross-border services, international transport, and supplies into Non-Tariff Zones consumed there and used directly for export production (Article 9 of the VAT Law) | Export manufacturing, Export Processing Enterprises (EPEs), cross-border logistics, import-export operations |
| 5% | Essential commodities: clean water, medical equipment, pharmaceuticals, educational supplies, agricultural products and services | Healthcare devices, pharmaceutical distribution, educational institutions, post-harvest agricultural processing |
| 8% | Temporary 2% rate reduction from the 10% standard baseline under Resolution 204/2025/QH15 (effective through December 31, 2026) | Domestic wholesale and retail, fast-moving consumer goods (FMCG), technical support, standard commercial engineering |
| 10% | Standard baseline rate; mandatory for sectors excluded from the temporary 8% reduction | Telecommunications, financial services, banking, securities, insurance, real estate development, metal products, mining products (except coal) |
| Exempt (Non-Taxable) | Statutory non-taxable transactions under Article 5 of the VAT Law | Financial derivatives, life insurance, land-use rights transfers, medical examination and treatment services |
To review specific amendments governing 0% eligibility conditions, on-spot export procedures, and the VND 5 million non-cash threshold, refer to our analysis of Vietnam new VAT law changes. Technical distinctions between exempt supplies, 0% supplies, and non-declaration transactions are detailed in our guide on distinguishing non-taxable and non-creditable VAT.
Mixed-Supply Allocation Rules
Enterprises that concurrently supply goods and services subject to different VAT rates must maintain separate accounting records to track turnover for each respective rate bracket. Under the VAT Law, failure to maintain separate accounting requires the tax authority to assess the highest applicable rate across the enterprise entire gross revenue.
For input VAT incurred on shared operational assets and overhead costs (such as head office leases, enterprise software, plant utilities, and administrative expenses) that cannot be segregated between taxable and exempt business lines, creditable input VAT is calculated proportionally based on the turnover ratio of taxable sales to total sales generated during the filing period. Errors in calculating shared input allocation ratios represent a leading cause of audit disallowances during VAT refund applications.
Taxable Turnover encompasses revenue from 0%, 5%, 8%, and 10% supplies, while Total Gross Turnover includes all taxable plus exempt revenue streams generated during the declaration period.
Input-Output Credit Mechanics and Cash Flow
VAT is an indirect tax operating as a tax credit pass-through mechanism across three components:
- Output VAT: Tax collected on behalf of the state treasury from customers upon issuing commercial sales invoices.
- Input VAT: Tax paid to domestic suppliers or at customs upon purchasing raw materials, capital equipment, and operational services.
- Net VAT Liability: Determined by the statutory formula
Net VAT Payable = Output VAT − Creditable Input VAT. A negative net balance carries forward to the subsequent period or qualifies for a cash refund under statutory channels.
Tax Filing Cycles: Monthly vs. Quarterly Thresholds
Under Article 19 of Circular 89, the VAT declaration cycle depends on gross commercial turnover, with filing deadlines under Article 10 of Decree 252/2026/ND-CP:
| Filing Frequency | Turnover Determination Threshold | Statutory Submission and Remittance Deadline | Operational Fit |
|---|---|---|---|
| Monthly Filing | Gross turnover in the preceding calendar year exceeding VND 50 billion | The 20th day of the month immediately following the reporting period | High-volume manufacturing, large-scale trading, established multinational subsidiaries |
| Quarterly Filing | Gross turnover in the preceding calendar year of VND 50 billion or less (quarterly filing is optional) | The last day of the first month immediately following the reporting quarter | Early-stage FDI startups, investment projects, small and medium enterprises |
Newly established enterprises may choose quarterly filing. If turnover in the preceding calendar year exceeds VND 50 billion, the enterprise files monthly. The filing cycle stays fixed for the whole calendar year; to change it, the enterprise submits Form 01/ĐK-TĐKTT by January 31.
Conditions for Input VAT Credit Deductibility
Not all input VAT stated on vendor invoices is automatically creditable. Enterprises must simultaneously satisfy three mandatory statutory conditions:
- Legitimate Electronic Invoices: Supported by authentic e-invoices containing accurate enterprise names, addresses, and tax codes, verified by cryptographic digital signatures in compliance with Decree 254/2026/ND-CP (which replaced Decree 123/2020/ND-CP from July 1, 2026).
- Documented Non-Cash Payment: Supported by non-cash banking payment vouchers for all transactions with an invoice value of VND 5 million or more (inclusive of VAT).
- Business Operational Nexus: The purchased goods and services must serve the enterprise direct production, trading, or administrative operations connected with taxable revenue generation.
Cash Payment Audit Trap: Settling an invoice of VND 5 million or higher using physical cash causes the enterprise to lose 100% of the input VAT credit across the entire transaction value, rather than merely the portion exceeding the threshold. When clerical errors occur, taxpayers retain the legal right to submit supplementary declarations within 5 years from the filing deadline, and corrections should normally be submitted before tax authorities announce a formal audit or inspection decision at enterprise premises. Some cases still allow later supplementary filing, though the taxpayer may then be treated as if the tax authority had found the error (Article 12.5 of Law on Tax Administration No. 108/2025/QH15).
Supplier Invoicing Risk: Buyer Liability and Audit Defense
The buyer loses the input VAT credit when an invoice fails the conditions or arises from a prohibited act (Articles 13-14 of the VAT Law); the buyer then owes the tax back plus late-payment interest.
Common vendor invoice irregularities that trigger disallowance:
- Supplier tax code locked, suspended, or closed by the tax authority prior to invoice issuance.
- E-invoices generated through unregistered software without cryptographic integration to the tax authority’s clearing engine.
- Invoice descriptions inconsistent with actual physical delivery, or lacking underlying commercial contracts, purchase orders, and goods receipt dockets.
- Suppliers classified on the tax authority’s high-risk register or suspected of trading in fraudulent invoices.
Recommended Monthly Vendor Verification Protocol
To safeguard input credits and maintain audit readiness, finance teams should institutionalize a four-step monthly internal control protocol:
- Tax Code Status Verification: Query supplier tax codes on the tax authority’s national database (
tracuunnt.gdt.gov.vn) before authorizing payment vouchers. - Bank Voucher Matching: Ensure every invoice meeting or exceeding VND 5 million has an associated bank transfer advice matching the supplier registered bank account name.
- Risk Pattern Identification: Scrutinize recently established vendors displaying sudden turnover spikes, frequent legal address changes, or vague commercial descriptions.
- Synchronized Archive Preservation: Bind executed contracts, purchase orders, delivery notes, and bank payment vouchers together with original invoice XML files to support future audit defense.
For manufacturing and export enterprises managing extensive supply chains, a single non-compliant vendor can freeze an entire multi-billion Dong VAT refund dossier. Implementing rigorous vendor verification protocols is essential to preserve credit and refund eligibility.
The Three Statutory VAT Refund Channels for FDI
Under Law on Value Added Tax No. 48/2024/QH15, Decree 181/2025/ND-CP, and Circular 69/2025/TT-BTC, the three most common cash VAT refund channels for FDI enterprises are set out below (further cases include dissolution, bankruptcy, carried-in goods and ODA programs):
Channel 1: Investment Projects
Enterprises in the pre-revenue investment phase incurring input VAT on factory construction, land preparation, and capital machinery qualify for cash refunds when meeting the following conditions:
- Uncredited input VAT of the investment project, after offsetting against VAT payable on any operating activity, reaches VND 300 million or more.
- For a project, phase, or item that has been completed without a refund yet, the application is submitted within one year of completion, meaning the date the project generates revenue (excluding trial-run revenue, financial income, and proceeds from selling materials), under Article 30 of Decree 181.
Enterprises must submit a dedicated VAT return for the investment project using Form 02/GTGT, segregated completely from general operational filings under Form 01/GTGT. Commingling operational and investment expenses is the most frequent reason tax authorities reject investment refund claims. See our detailed walkthrough on investment VAT refund procedures.
Channel 2: Export Operations
Enterprises generating revenue from qualifying export goods and cross-border services qualify for cash refunds when meeting two statutory conditions:
- Input VAT on exported supplies, after offsetting against VAT payable on domestic sales, remains at VND 300 million or more.
- The refundable amount cannot exceed 10% of total export revenue generated within the refund period (Article 29.2 of Decree 181); the method for determining the refundable amount follows Appendix II of Circular 69. Any uncredited input VAT exceeding this 10% ceiling carries forward to subsequent filing periods.
Under Decree 252, a refund-first dossier is resolved within 6 working days of the tax authority’s acceptance notice, while an audit-first dossier (including the first refund for each project or case) receives a decision within 10 working days of the conclusion of the on-site inspection (Article 31). For step-by-step guidance on dossier preparation, review our guide to VAT refund for FDI.
Channel 3: Businesses Operating Exclusively at the 5% Rate
Under the VAT Law (Article 15), production enterprises operating exclusively in goods and services subject to the 5% VAT rate qualify for refunds if uncredited input VAT reaches VND 300 million or more after 12 consecutive months or 4 consecutive quarters.
This targeted policy provides direct liquidity relief to suppliers of medical equipment, medicines, clean water, and agricultural products. Businesses with several VAT rates can still seek a refund of input VAT attributable to their 5% production activity, provided they account for it separately or allocate shared input VAT by revenue ratio.
Foreign Contractor Tax (FCT) Overlap: Deemed VAT on Cross-Border Services
Foreign Contractor Tax (FCT) includes a deemed VAT component triggered when a Vietnamese enterprise pays cross-border service fees to foreign suppliers lacking a Vietnamese permanent establishment (such as group management fees, technical consulting, and machinery rental).
Deemed VAT and CIT withholding percentages are governed by Circular 69/2025/TT-BTC (VAT component), Circular 20/2026/TT-BTC (CIT component), and Circular 89/2026/TT-BTC (formally superseding legacy Circular 103/2014/TT-BTC):
| Cross-Border Service Category | Deemed VAT Rate | Deemed CIT Rate | Total Effective Withholding Rate |
|---|---|---|---|
| General Services & Technical Consulting | 5% | 5% | 10% |
| Group Management & Advisory Fees | 5% | 5% | 10% |
| Software Licensing & Royalties | Not subject to VAT if software, technology transfer or IP ownership transfer (Article 5 of the VAT Law); pure licences assessed case by case | 10% | 10% |
| Construction & Installation (with supply of materials) | 3% | 2% | 5% |
| Machinery & Equipment Rental | 5% | 5% | 10% |
Contract Drafting Note: Cross-border agreements must explicitly stipulate whether contract pricing is Net or Gross of Vietnamese withholding taxes. Under a Net contract, the Vietnamese enterprise absorbs all local taxes and must mathematically gross-up taxable revenue, raising the tax base, and therefore the cost, by the amount of the contractor tax.
When a foreign contractor registers to declare tax directly under Article 30 of Circular 89, the contractor issues electronic invoices and files VAT directly. Where the Vietnamese enterprise pays the tax on the foreign party’s behalf, the tax payment document serves as the input VAT credit document. Full procedural instructions are available in our guide to foreign contractor tax withholding.
Statutory Filing Deadlines and Compliance Calendar
Enterprises must strictly adhere to the compliance timetable established under the Law on Tax Administration:
| Statutory Obligation | Submission & Payment Deadline | Operational Notes |
|---|---|---|
| Initial Tax Registration | Issued together with the ERC through the interconnected mechanism | Synchronized with e-invoice activation |
| Monthly VAT Declaration (Form 01/GTGT) | The 20th day of the subsequent calendar month | Applies to enterprises with prior year revenue > VND 50B |
| Quarterly VAT Declaration (Form 01/GTGT) | Last day of the first month following reporting quarter | Applies to enterprises with prior year revenue ≤ VND 50B |
| VAT Refund Dossier Submission | Rolling basis once eligibility thresholds are satisfied | 6 working days (refund first); 10 working days after inspection conclusion (audit first) |
| Annual Financial Statement Reconciliation | By the last day of the 3rd month after fiscal year-end | CIT finalization deadline; VAT has no annual finalization return |
Administrative penalties for late submission of tax declarations range from VND 2,000,000 to VND 25,000,000 depending on delinquency duration under Article 13 of Decree 125/2020/ND-CP (as amended by Decree 310/2025/ND-CP); the VND 25,000,000 level applies only to delays above 90 days where tax is due and was paid in full, with late-payment interest, before the tax authority announced an inspection decision. These are fines for organizations; individuals and household businesses pay half. Late payment interest accrues at a statutory rate of 0.03% per calendar day on outstanding tax liabilities under Article 16 of Law on Tax Administration No. 108/2025/QH15.
Codified under Article 16 of the Tax Administration Law. Accrues continuously on a calendar-day basis without statutory cap until the principal debt is fully settled into the state treasury.
Calculation Example: An enterprise assessed VND 500,000,000 in underdeclared VAT following an audit inspection with a 60-day settlement delay incurs late payment interest of:
VND 500,000,000 × 0.03% × 60 days = VND 9,000,000.
