Vietnam continues to be one of Southeast Asia’s most attractive destinations for foreign direct investment, with manufacturing, technology, services, and trading sectors drawing billions in FDI annually. But for foreign enterprises setting up or operating in Vietnam, one operational challenge consistently ranks at the top: navigating Vietnam’s accounting and tax compliance landscape.
This guide covers everything foreign-invested enterprises need to know about Accounting & Assurance Services in Vietnam in 2026 — from regulatory requirements and cost comparisons to choosing the right accounting partner.
What Does Accounting & Assurance Services Cover for FDI Companies?
Under Vietnamese law (the Law on Accounting No. 88/2015/QH13, amended 2024, and its guiding decrees), all enterprises operating in Vietnam — including 100% foreign-owned companies, joint ventures, and representative offices — must maintain accounting records in Vietnamese Dong (VND) and comply with Vietnamese Accounting Standards (VAS).
A comprehensive Accounting & Assurance Services package for an FDI enterprise typically includes:
| Service Component | What It Covers | Frequency |
|---|---|---|
| Bookkeeping & General Ledger | Recording all transactions, maintaining chart of accounts per Circular 200/2014/TT-BTC or 133/2016/TT-BTC | Daily/Weekly |
| Tax Declarations | VAT (monthly/quarterly), CIT (quarterly provisional + annual finalization), PIT (monthly/quarterly), foreign contractor tax (FCT) | Monthly/Quarterly |
| Payroll & Social Insurance | Salary calculation, PIT withholding, social insurance (SI), health insurance (HI), unemployment insurance (UI) registration and reporting | Monthly |
| Financial Statements | Annual financial statements per VAS: Balance Sheet, Income Statement, Cash Flow Statement, Notes to FS | Annual |
| Tax Finalization | Year-end CIT finalization, PIT finalization for employees, transfer pricing documentation (if applicable) | Annual |
| Invoice Management | E-invoice issuance, storage, and reporting per Decree 123/2020/ND-CP | Per transaction |
| Compliance Advisory | Updates on tax law changes, VAT refund eligibility, tax incentive applications, audit support | Ongoing |
In-House vs. Outsourced Accounting: Cost Comparison 2026
For many foreign SMEs in Vietnam, the decision between hiring an in-house accountant and outsourcing to a professional firm is critical. Here’s a realistic cost comparison:
| Cost Item | In-House (1 Accountant) | Outsourced (Full Package) |
|---|---|---|
| Monthly Salary (qualified accountant) | 15,000,000 – 25,000,000 VND | — |
| Social Insurance (21.5% employer contribution) | 3,225,000 – 5,375,000 VND | — |
| Annual Bonus (13th month + Tet) | 2,500,000 – 4,000,000 VND/month (amortized) | — |
| Software & Tools | 1,000,000 – 3,000,000 VND/month | Included |
| Training & Updates | Variable | Included |
| Risk of Errors / Penalties | Employer bears full risk | Shared / covered by service agreement |
| Total Monthly Cost | 22,000,000 – 38,000,000 VND | 5,000,000 – 15,000,000 VND |
Outsourcing saves 55-80% compared to an in-house team — and you gain access to a team of specialists instead of relying on one person.
VAS vs. IFRS: What Foreign Companies Must Know
One of the most common points of confusion for foreign investors is the relationship between Vietnamese Accounting Standards (VAS) and International Financial Reporting Standards (IFRS).
Key differences that impact FDI companies:
- Reporting currency: VAS requires VND; IFRS allows functional currency. Dual-book systems are common for group reporting.
- Fixed assets: VAS uses historical cost with prescribed depreciation rates; IFRS allows revaluation model.
- Revenue recognition: VAS is more rules-based; IFRS 15 is principles-based.
- Provisions & impairment: IFRS requires expected credit loss models; VAS is less prescriptive.
- Leases: VAS (Circular 200) still uses operating/finance lease classification; IFRS 16 requires all leases on balance sheet.
Practical solution: Most FDI companies maintain VAS-compliant books for statutory reporting and prepare IFRS adjustments for group consolidation. A professional accounting firm can handle both.
E-Invoice Mandate: What FDI Companies Need to Know
Since July 1, 2022, all enterprises in Vietnam — including FDI companies — have been required to use e-invoices with tax authority codes under Decree 123/2020/ND-CP. Key requirements:
- All sales invoices must be electronic and registered with the tax authority
- Invoice data must be transmitted to the tax authority in real-time or within 24 hours
- Invoice numbers are sequential and verified by the tax authority’s system
- Non-compliance penalties range from 1,000,000 to 8,000,000 VND per violation (Decree 125/2020/ND-CP)
Common Pitfalls for Foreign Enterprises in Vietnam
- Ignoring Foreign Contractor Tax (FCT): Payments to overseas suppliers for services, software licenses, or royalties trigger FCT liability. The withholding rates are: 5% VAT + 5% CIT (services), or 0% VAT + 10% CIT (royalties).
- Missing Transfer Pricing Documentation: Companies with related-party transactions exceeding 30 billion VND in revenue OR having transactions with related parties outside Vietnam must prepare transfer pricing documentation under Decree 132/2020/ND-CP.
- Late VAT Declaration: Even one day late triggers penalties of 2,000,000 – 25,000,000 VND plus late payment interest (0.03%/day).
- Incorrect Expense Deductibility: Not all expenses are deductible for CIT. Common disallowed items: personal expenses, expenses without valid invoices, depreciation exceeding prescribed rates, and provisions not yet incurred.
- PE Risk from Dependent Agents: Having a representative office or dependent agent in Vietnam that negotiates or signs contracts can create a Permanent Establishment (PE), subjecting the foreign company to CIT in Vietnam.
How to Choose an Accounting Partner in Vietnam
5 selection criteria:
- FDI experience: Look for firms with a track record serving foreign-invested enterprises — they understand group reporting requirements, dual-language communication, and cross-border transaction complexities.
- Certifications: Ensure the firm has licensed chief accountants (Chung chi Ke toan truong) and tax agents (Chung chi Dai ly thue).
- Technology: The firm should use licensed accounting software compatible with Vietnam’s e-invoice and tax declaration systems (HTKK, iTaxViewer).
- Responsiveness: VAT refunds, tax audits, and urgent compliance queries require fast turnaround. Test their response time before committing.
- English proficiency: Your accounting partner must communicate clearly in English — both verbally and in written reports — to bridge the gap between local regulations and your headquarters’ requirements.

Frequently Asked Questions
Do foreign companies need a local accounting firm in Vietnam?
Yes. Vietnamese law requires all enterprises — including FDI companies — to maintain VAS-compliant books in VND, file monthly/quarterly tax declarations, and submit annual financial statements. While you can hire in-house staff, most foreign SMEs find outsourcing to a professional firm more cost-effective and lower-risk.
What is the minimum capital requirement for an FDI company in Vietnam?
There is no fixed minimum capital for most sectors under the Law on Investment 2020, but the licensing authority will assess whether the proposed capital is “adequate” for the business plan. For trading companies, 200,000 – 500,000 USD is typical; for manufacturing, 500,000 – 1,000,000+ USD is common. Certain sectors (banking, insurance, real estate) have specific minimums.
How long does it take to set up accounting for a new FDI company?
Initial setup takes 2-3 weeks: registering with the tax authority, obtaining e-invoice credentials, setting up the chart of accounts, and registering employees for social insurance. After setup, monthly bookkeeping runs on a regular schedule.
Can an FDI company use IFRS instead of VAS for statutory reporting?
No. Statutory financial statements must be prepared under VAS. However, companies can maintain IFRS-based management accounts for internal/group reporting purposes. Most FDI companies prepare VAS statutory reports and separately produce IFRS adjustments for consolidation.
