Foreign investors accumulating input VAT during Vietnam’s pre-operational investment phase can recover these costs before generating revenue—but eligibility conditions are stricter than operational refunds and governed by Law 48/2024/QH15, Article 15, Clause 2 (effective July 1, 2025), with detailed implementation procedures specified in Decree 181/2025/ND-CP, Article 30.
The 1-year investment period requirement was previously abolished by Decree 49/2022/ND-CP, with refunds available once input VAT reaches 300 million VND after offsetting. However, foreign-invested enterprises must submit refund applications within one year from the date the investment project commences revenue generation (Law 48/2024/QH15, Article 15, Clause 2, Point a)—missing this deadline forfeits refund rights. Additionally, separate declaration filing, complete documentation chains, and conditional business line scrutiny create rejection rates exceeding 30% for first-time applicants.
Foreign investors can recover pre-operational VAT once accumulated input reaches 300 million VND through separate declaration filing, though strict documentation requirements and enhanced scrutiny of conditional business sectors cause 30% first-time rejection rates that delay cash flow recovery by 3-6 months.
Executive Key Takeaways
- Financial Impact: Input VAT ≥300 million VND accumulated during investment phase qualifies for a refund.
- Critical Deadline: Applications must be submitted within one year from the date the investment project commences revenue generation (Law 48/2024/QH15, Article 15, Clause 2, Point a)—missing this deadline forfeits refund rights
- Legal Compliance: Separate VAT declaration required for investment projects not yet operational; mixing with operational business declarations triggers rejection
- Timeline Reality: Tax authority processing takes 40 working days for standard cases, but incomplete dossiers restart the clock—expect 60-90 days in practice
- Strategic Risk: Projects in conditional business lines (real estate, mining, securities trading) face additional scrutiny; refund denial rates exceed 30% for first-time applicants
- Documentation Critical: Form 01/HT + Investment Registration Certificate (IRC) + Land Use Rights Certificate + complete invoice chain—missing any single document = automatic rejection
- Supplier Compliance Update: Effective January 1, 2026, supplier tax compliance verification is no longer required for investment VAT refund applications (Decree 359/2025/ND-CP)
Investment VAT Refund Eligibility: VND 300 Million Threshold & 1-Year Deadline
Effective January 1, 2026, Decree 359/2025/ND-CP removed the requirement that sellers must have declared and paid VAT before buyers can claim refunds. This requirement existed only briefly under Decree 181/2025/ND-CP Article 37.3 (July 1, 2025 – December 31, 2025), making compliance significantly easier for refund applicants starting in 2026.
Your investment project qualifies for VAT refund when accumulated input VAT reaches 300 million VND after offsetting against output VAT. This requirement is governed by Law 48/2024/QH15, Article 15, Clause 2 (effective July 1, 2025) and detailed in Decree 181/2025/ND-CP, Article 30. Implementation procedures are specified in Circular 69/2025/TT-BTC regulatory updates, which superseded prior guidance including Circular 80/2021/TT-BTC and Circular 13/2023/TT-BTC. The project must use the deduction method and file separate VAT declarations from operational business activities.
New investment projects differ from expansion projects. A new investment project establishes a distinct legal entity or production facility with separate Investment Registration Certificate (hereinafter “IRC”) issued by provincial authorities. Expansion projects modify existing registered capital or production capacity within the same legal entity. The General Department of Taxation scrutinizes this distinction—misclassification triggers automatic rejection.
⚠️ CRITICAL DEADLINE (2026): Foreign-invested enterprises must submit VAT refund applications within one year from the date the investment project commences revenue generation (Law 48/2024/QH15, Article 15, Clause 2, Point a). Missing this deadline forfeits VAT refund rights—a foreign investor starting operations in June 2025 must submit by June 2026, regardless of when construction began. The previous 1-year construction period requirement no longer applies under current regulations.
The 300 million VND (~USD 12,000) threshold is specified in Article 15.2.a of VAT Law 48/2024. The calculation methodology: Sum all input VAT from investment-phase purchases, including machinery, construction materials, and consulting services. Subtract any output VAT if the project generated incidental revenue during construction. The remaining undeducted VAT must reach 300 million VND minimum per tax period (not cumulative across periods).
Conditional business lines face additional requirements. Projects in real estate development, mining, securities trading, or other sectors requiring special licenses must demonstrate full compliance with investment conditions before refund approval. Understanding the Vietnam tax system for FDI enterprises is essential for navigating these enhanced requirements. The Ministry of Finance reviews these applications with heightened scrutiny—processing times extend beyond standard 40-day periods.
| Eligibility Criterion | Requirement | Verification Document |
|---|---|---|
| Input VAT Threshold | ≥300 million VND | VAT declaration forms |
| Declaration Method | Deduction method registered | Tax registration certificate |
| Separate Filing | Investment VAT isolated from operations | Separate declaration submission |
| Investment Status | Pre-operational phase | Investment Registration Certificate |
Prior regulations, including Decree 209/2013/ND-CP (as amended by Decree 49/2022/ND-CP) and Circular 80/2021/TT-BTC, have been superseded by the new VAT Law provisions and Circular 69/2025/TT-BTC effective July 1, 2025.
Complete Refund Process: Documentation, Submission, and Timeline
The VAT refund process begins with Form No. 01/HT submission to your provincial tax authority where the investment project is registered. You must compile a complete dossier before submission—incomplete applications restart the 40-working-day processing clock from zero.
Required documents include Form 01/HT (official VAT refund application), certified copy of Investment Registration Certificate (IRC), Land Use Rights Certificate for project location, complete VAT invoice chain for all input purchases (with valid non-cash payments), project approval documents from investment licensing authority, and separate VAT declarations for the investment phase. Each document serves specific verification purposes per VAT Declaration Form 01/GTGT filing compliance requirements in Vietnam and implementing decrees effective July 1, 2025.
| Document | Purpose | Common Rejection Reason |
|---|---|---|
| Form 01/HT | Official refund request | Calculation errors, missing signatures |
| Investment Registration Certificate | Proves project legal status | Scope mismatch with purchases |
| VAT Invoice Chain | Verifies input VAT amounts | Incomplete chain, invalid invoices |
| Land Use Rights Certificate | Confirms project location | Name mismatch with IRC |
Submission Procedures Through the National Tax Portal
Refund applications are submitted electronically through the General Department of Taxation’s national portal at https://thuedientu.gdt.gov.vn. Foreign-invested enterprises require a valid digital signature certificate issued by approved certification authorities (VNPT-CA, FPT-CA, Viettel-CA, or BKAV-CA) to access the portal. Company legal representatives or authorized tax agents can submit applications with appropriate power of attorney documentation.
The submission process follows these steps:
- Log in to the national tax portal using digital signature credentials
- Select “VAT Refund Application” from the tax declaration menu
- Complete form 01/HT (VAT refund application form for investment projects) with refund category selection
- Upload supporting documents: IRC, Land Use Rights Certificate, VAT invoice chain, project approval documents, separate VAT declarations
- Submit application and receive automatic acknowledgment number
Tax authorities issue acknowledgment within 2 working days of electronic submission. The acknowledgment confirms application receipt and initiates the processing timeline. Incomplete applications receive rejection notices within 5 working days specifying missing documentation requirements. Corrected applications must be resubmitted within 30 days to maintain the original application date for threshold calculation purposes.
Processing Timeline and Risk-Based Classification
The statutory processing timeline is 40 working days from complete dossier receipt under the “Audit First, Refund Later” procedure. Investment project refunds typically default to this audit-first approach due to their pre-operational nature and higher scrutiny requirements compared to operational export refunds.
However, tax authorities may apply risk-based classification depending on specific project characteristics:
- Low-risk investment projects (rare): Processed within 6 working days under “Refund First, Audit Later” for established FDI enterprises with multiple successful investment phases, consistent compliance history, and standardized project types
- Standard-risk investment projects: 15-20 working days for mid-sized projects from known investors with clean compliance records
- High-risk investment projects (most common): 40 working days requiring mandatory field inspection for first-time investors, conditional business lines, or refund amounts exceeding 1 billion VND
In practice, expect 60-90 days for first-time applicants. Tax authorities conduct field inspections for refund amounts exceeding 1 billion VND. Incomplete documentation restarts the clock—the 40-day period begins only after you submit all requested supplementary documents.
Decision timing depends on accumulated VAT amounts. If your project will generate more input VAT in upcoming months, consider waiting until the total reaches 500 million to 1 billion VND—this reduces administrative burden and multiple submission costs. However, if construction is complete and no further VAT will accumulate, submit immediately once the 300 million VND threshold is met to optimize cash flow recovery. Understanding capital account management in Vietnam during this period ensures proper documentation of VAT payments.
Provincial Processing Variations: Ho Chi Minh City and Hanoi maintain dedicated investment project units—processing times average 50-60 days for high-risk cases. Industrial zone authorities in provinces like Binh Duong or Dong Nai process applications within 40-50 days due to standardized project types and familiarity with FDI documentation requirements. Cross-province projects submit to the head office location specified in the IRC.
Risks and Common Rejection Triggers
VAT refund rejection for investment projects stems from four primary categories. Documentation gaps cause 40% of rejections—missing invoice chains, Investment Registration Certificate scope mismatches with actual purchases, or Land Use Rights Certificate name discrepancies with the IRC holder. Tax authorities reject applications immediately when any core document is absent.
Declaration errors account for 25% of rejections. The most common mistake: mixing investment-phase VAT with operational business declarations. Current regulations require separate declaration filing (Circular 69/2025/TT-BTC, effective July 1, 2025, which superseded Circular 13/2023/TT-BTC). If your company operates existing business lines while constructing a new facility, you must file two distinct VAT declarations—one for operations, one for investment. Combining them triggers automatic rejection.
Conditional business lines face rejection rates exceeding 30%. Projects in real estate development, mining, securities trading, or other sectors requiring special licenses undergo enhanced scrutiny. Tax authorities verify full compliance with investment conditions before approving refunds. A real estate project without completed land clearance or a mining project lacking environmental permits will face rejection regardless of documentation completeness. For complex structures, Transfer Pricing documentation requirements may also apply if related parties are involved in project financing.
Audit triggers extend processing times and increase rejection risk. Refund amounts exceeding 1 billion VND require mandatory field inspections. First-time applicants face higher scrutiny—tax authorities verify the entire invoice chain and conduct supplier verification for applications submitted July 1 – December 31, 2025 (this requirement was removed January 1, 2026 by Decree 359/2025/ND-CP). Cross-province projects where suppliers are located in different provinces than the project site trigger additional documentation requests.
| Common Mistake | Consequence | Prevention |
|---|---|---|
| Mixed declarations | Immediate rejection, 3-month delay | File separate investment VAT declarations |
| Incomplete invoice chain | Supplementary document request, 60-day restart | Verify all invoices before submission |
| IRC scope mismatch | Rejection, potential audit trigger | Ensure purchases align with registered activities |
| Premature submission | Below 300M VND threshold rejection | Calculate accumulated VAT accurately before filing |

Conclusion
VAT refund eligibility for investment projects requires accumulated input VAT of at least 300 million VND with separate declaration filing—the abolished 1-year investment period no longer applies under current regulations. Complete documentation on first submission prevents 3-6 month delays from rejection cycles that restart processing timelines. Province-specific processing variations and conditional business line scrutiny require experienced navigation to optimize cash flow recovery during pre-operational phases.
Effective January 1, 2026, supplier tax compliance verification is no longer required for investment VAT refund applications (Decree 359/2025/ND-CP), significantly simplifying the refund process for foreign investors.
