FDI Accounting in Vietnam: Setup, Bookkeeping & Financial Statements

For a Foreign Direct Investment (FDI) enterprise in Vietnam, accounting is a strict operational cycle tied directly to state tax administration and foreign capital control. It demands flawless compliance from the day the Enterprise Registration Certificate (ERC) is issued.

Unlike western frameworks where accounting primarily serves shareholders, Vietnamese Accounting Standards (VAS) dictate exactly how revenues are recognized, how costs are captured, and how internal records are maintained.

With the fundamental modernization introduced by Circular 99/2025/TT-BTC (effective January 1, 2026), FDI finance teams face new rules for organizing their general ledgers and presenting financial data. This is the master guide to the end-to-end accounting lifecycle for FDIs in Vietnam: from initial software mapping to the final 90-day filing deadline.

Phase 1: The Initial Setup (Accounting Regime & Personnel)

New FDI companies are expected to have a compliant accounting apparatus running within the first 30 days of ERC issuance. Delaying this foundation often leads to rejected setup expenses and tax penalties during the first audit season.

Selecting Between Circular 99/2025 and Circular 133/2016

Vietnam operates a bifurcated accounting regime. Your choice determines your chart of accounts (COA) structure and financial statement format:

1. Circular 99/2025/TT-BTC (Comprehensive Regime): Replaces the legacy Circular 200. It applies to large enterprises, complex operations, and most manufacturing FDIs. The detailed COA structure is heavily utilized to support Transfer Pricing compliance.
2. Circular 133/2016/TT-BTC (Simplified Regime): Designed for SMEs. While easier to maintain initially, switching from Circular 133 to Circular 99 as operations scale requires an expensive, retroactive account mapping overhaul.

Chief Accountant vs. Person in Charge Requirements

A common myth is that an FDI startup must hire a full-time Chief Accountant on Day 1. Under Decree 174/2016/ND-CP, newly established enterprises actually enjoy a 12-month grace period to appoint a formal Chief Accountant.

However, they are legally required to appoint a “Person in Charge of Accounting” immediately. Without this designated person, you cannot activate corporate bank accounts or secure an eTax profile. Most new FDIs outsource this role to a licensed local accounting firm to guarantee rapid operational startup.

Fast-Tracking E-Invoice Registration

(Note: Full e-invoice mechanics are usually covered during initial corporate tax registration.) Under Decree 123/2020/ND-CP, paper invoices are obsolete. Before making any commercial sale, FDIs must register for an e-invoice issuing software and sync it with the General Department of Taxation’s portal. The vast majority of startups must use “Authentication-Code” e-invoices, meaning the GDT server validates every invoice before it is sent to a buyer.

Phase 2: System Configuration (ERP & Chart of Accounts Map)

Before recording the first transaction, the enterprise must operationally configure its bookkeeping software. This is where dual-reporting complexity begins for multinational subsidiaries.

Structuring the VAS Chart of Accounts

Unlike IFRS, where a company can design an arbitrary account structure, Vietnam legally mandates standardized account root numbers. Under Circular 99/2025, you cannot invent a completely new account code without prior tax authority notification. For example, manufacturing FDIs are expected to structure their cost accounts (621 to 627) meticulously by production line or department to satisfy specialized cost-of-goods-sold audits in the future.

Solving the “IFRS to VAS” ERP Disconnect

For subsidiaries, running local Vietnamese software (like MISA) creates an immediate disconnect with the parent company’s global ERP (SAP, Oracle, NetSuite). The standard operational choice is the “IFRS-First” Strategy:

1. Run daily bookkeeping in the global ERP using IFRS rules and the parent’s primary functional currency for real-time management awareness.
2. Utilize local “Mapping Tables” or middleware modules to systematically translate IFRS transaction data into a VAS-compliant trial balance at month-end.

Phase 3: Daily Bookkeeping Operations & The E-Invoice Trap

Foreign CFOs commonly assume that a signed service contract and an international bank wire are sufficient to claim a Corporate Income Tax (CIT) deduction. Under Vietnamese law, this assumption is catastrophic.

The Strict Definition of a “Valid Voucher” for CIT Deduction

An expense is only recognized as a deductible cost if it is backed by a “valid voucher.” For domestic purchases, this almost exclusively means an Electronic Invoice (Hóa đơn điện tử) that contains a unique GDT validation code.

If your bookkeeping team processes a VND 500 million expense through a domestic bank transfer but fails to collect the state-coded e-invoice from the supplier, tax authorities will forcefully eject that expense during your tax audit, retroactively inflating your taxable profit and triggering CIT arrears plus 0.03% daily late interest.

Best Practices for Multi-Currency Transaction Tracking

While the Ministry of Finance allows specific FDIs to nominate a foreign functional currency internally, Vietnam strictly requires that all transactions be parallel-tracked. Every single foreign currency transaction must be booked alongside its Vietnamese Dong (VND) equivalent, calculated using the commercial bank’s exact daily exchange rate.

Phase 4: Year-End Closing & Mandatory Reconciliation

When the fiscal year ends, the finance team pivots from daily data entry to “closing the books”—a phase that involves heavy manual reconciliation due to variations between local and international accounting rules.

Recognizing IFRS vs. VAS Timing Differences

VAS is notoriously rigid regarding revenue recognition. If a parent company uses IFRS 15 to recognize recurring software license revenue proportionally over time, they will clash with VAS, which often requires immediate revenue recognition matching the date the VAT e-invoice is issued.

Before preparing the local financial statements, the Chief Accountant must meticulously document these “timing differences.” Undocumented discrepancies between global reports and Vietnamese tax filings are immediate red flags for inspectors.

The Consolidation Rule for FDI Branch Operations

If a company establishes a Head Office in Ho Chi Minh City, a factory in Binh Duong, and a sales branch in Hanoi, the Head Office must issue a single, consolidated Financial Statement for the entire legal entity. Circular 99 mandates that all internal transactions (such as transferring inventory internally between branches) must be entirely eliminated. Failing to do so artificially inflates gross revenue, skewing tax ratios and triggering scrutiny.

Phase 5: Generating the 4 Mandatory Financial Statement Components

Once reconciled, the data is injected into state-prescribed templates. A compliant statutory filing under Circular 99/2025 must include these 4 specific components:

1. The Statement of Financial Position

Previously known as the Balance Sheet, Circular 99 officially renames this to the Statement of Financial Position (Báo cáo tình hình tài chính). The modernized statement accommodates dedicated lines for new classifications like Biological Assets (Account 215) and properly reclassifies mandatory dividend-paying preference shares as financial liabilities rather than equity.

2. The Statement of Comprehensive Income

Formerly the Income Statement, this details revenues, cost of goods sold, and financial expenses (including heavily scrutinized foreign exchange losses). The gross revenue reported here must perfectly mirror the accumulated total of all e-invoices issued throughout the fiscal year.

3. The Statement of Cash Flows (DICA Alignment)

Categorizes cash movements into Operating, Investing, and Financing activities. The State Bank of Vietnam (SBV) uses this statement to verify whether foreign loan drawdowns and equity injections strictly align with the enterprise’s Direct Investment Capital Account (DICA) regulations.

4. Notes to the Financial Statements

The Notes (Thuyết minh báo cáo tài chính) are often the most heavily audited section. They require detailed, mandatory written disclosures regarding:

• Functional currency methodologies.
• Related-party transactions and transfer pricing data.
• Disclosures regarding Global Minimum Tax (Pillar Two) obligations using the new Account 82112 under Circular 99.

Phase 6: Statutory Audit & The 90-Day Filing Process

You cannot simply generate financial statements from your ERP, sign them, and upload them to the government. They must be validated by an external authority.

Pre-requisite: The Independent Statutory Audit

All foreign-invested enterprises in Vietnam—with zero exceptions—are subject to a mandatory annual statutory audit.

Before financial statements are filed, an independent, Vietnamese-licensed CPA firm must audit the books and issue an audit opinion. Submitting unaudited financial statements is equivalent to not submitting them at all.

Concurrent Submission to Multiple State Agencies

The universal deadline for submitting annual financial statements is 90 days from the end of the fiscal year (March 31 for a standard calendar year).

Vietnam does not have a single unified corporate portal. The audited financial statements must be submitted concurrently to:

1. The Tax Authority: Submitted electronically via the eTax portal.
2. The Department of Planning and Investment (DPI): Serving as the foundation for your FDI Periodic Reporting via the National Investment Information System.
3. The General Statistics Office (GSO): Submitted electronically for state economic data modeling.
4. Parent Company and Licensing Authority: As mandated by Circular 200/2014/TT-BTC limits on filing distribution.

Consequences of Missed Deadlines on Profit Repatriation

Missing the 90-day deadline, or failing to secure the independent audit prerequisite, triggers severe corporate consequences:

• Administrative Fines: Filing late incurs fines under Decree 41/2018/NĐ-CP. Actively providing false data pushes regulatory fines up to VND 40-50 million.
• The Profit Repatriation Blockade: A company cannot legally remit dividends back to its overseas parent entity unless it has submitted audited financial statements, completed annual tax finalization, and received confirmation that its CIT obligations are formally cleared by the State.
• Arbitrary Tax Imposition: Persistent failure to submit permits the Tax Authority to assume the company is committing tax evasion, authorizing them to arbitrarily impose a tax liability based on regional industry averages.

Managing the accounting cycle in Vietnam is an operational marathon. If daily bookkeeping is flawed—if valid e-invoices are missed or internal records are incompatible with VAS—the year-end closing process collapses, dragging the statutory audit past the 90-day deadline and ultimately blocking profit repatriation to the parent company.
