Choosing the wrong structure at the outset is the costliest mistake a foreign investor can make: it means dissolving, setting up a new entity, transferring contracts and redoing tax registrations. This article compares 5 common forms of foreign investment in Vietnam against the criteria management actually needs: can you book revenue, how long does it take, and how heavy are the accounting and tax obligations. It is written by the FDI accounting team at ACCA Consulting Vietnam from the perspective of post-licensing operations.
1. The 5 most common forms of foreign investment in Vietnam
In practice, most foreign investors weigh up five options. Each serves a different purpose, so the right question is not “which form is best?” but “what are our goals for the next 2–3 years?”.
- Wholly foreign-owned company: the foreign investor owns 100%, usually following the route of an Investment Registration Certificate (IRC – Giấy chứng nhận đăng ký đầu tư) and then an Enterprise Registration Certificate (ERC – Giấy chứng nhận đăng ký doanh nghiệp).
- Joint venture: the foreign investor and a Vietnamese partner set up, or contribute capital to, a shared legal entity.
- Representative office (RO – Văn phòng đại diện): a dependent unit of a foreign trader, used for promotion and market research, not for direct profit-making business.
- Branch of a foreign trader: a dependent unit permitted to conduct commercial activities within its licensed scope, but not an independent legal entity.
- Capital contribution or share acquisition: the foreign investor buys into an existing Vietnamese company instead of setting up a new one.
2. Comparison table across 5 decision criteria
The table below summarizes the core differences. Statutory timelines are given only where they are clearly established; other procedures depend on the business line, location and quality of the application, and need to be assessed case by case.
| Form | Legal status | Can book revenue | Main procedures | Accounting – tax obligations |
|---|---|---|---|---|
| Wholly foreign-owned company | Vietnamese legal entity | Yes | IRC (15 days if investment policy approval is not required) + ERC (3 working days) | Full: periodic returns, audited annual financial statements, CIT and PIT finalization |
| Joint venture | Vietnamese legal entity | Yes | As for a wholly foreign-owned company, or capital contribution into an existing company | Full as above, plus reporting to multiple shareholders |
| Representative office | Not a legal entity, dependent on the parent company | No profit-making business | RO establishment license under current regulations | Mainly PIT withholding and filing, employee insurance; periodic activity reports |
| Branch of a foreign trader | Not an independent legal entity | Yes, within the permitted scope | Branch license, narrow scope under current regulations | Accounting and tax as a business unit; requires specific advice |
| Capital contribution, share acquisition | Existing Vietnamese legal entity | Yes, from day one | May require prior registration of the capital contribution, then an ERC update | Inherits existing books; pre-transaction review needed |
3. Decision tree: 5 questions to choose your structure
Rather than comparing everything at once, answer the following questions in turn. Each answer eliminates some options.
- 1Do you need to issue invoices and collect payment in Vietnam?
If you only want to survey the market and liaise with customers, an RO is the lightest option; if you need revenue, rule out the RO.
- 2Do you want to ring-fence legal risk from the parent company?
If so, prefer a wholly foreign-owned company or a joint venture, as these are independent legal entities.
- 3Do you have a Vietnamese partner with licenses, customers or premises?
If so, consider a joint venture or share acquisition to shorten market entry.
- 4Is foreign ownership restricted in your business line?
Check market access conditions first; some sectors require a domestic partner.
- 5Have you found a target company with clean books?
Only acquire shares after a financial and tax review of the target company.
4. How accounting and tax obligations differ after licensing
This is the part investors tend to underestimate. A wholly foreign-owned company or joint venture must file value-added tax (VAT/GTGT) returns quarterly in its start-up phase (due on the last day of the first month of the following quarter), make quarterly provisional corporate income tax (CIT/TNDN) payments (due on the 30th of the first month of the following quarter), prepare annual financial statements and have them audited by an independent audit firm. Financial statements and the CIT finalization are due on the last day of the 3rd month after the financial year-end.
Capital must be transferred through a direct investment capital account (DICA) and fully contributed within 90 days of the ERC issue date. If you acquire shares, there is no “clean first year”: every past error in the books becomes the new owner's problem. A pre-transaction review is therefore usually far cheaper than the risk of back taxes later.
An RO carries a lighter corporate tax burden because it does not trade, but it must still pay compulsory insurance for Vietnamese employees (21.5% employer share and 10.5% employee share of the salary subject to social insurance) and withhold personal income tax (PIT/TNCN). See the limits on RO activities in what a foreign representative office can do.

5. Three common mistakes when choosing an investment form
- Using an RO to sign sales contracts. When an RO negotiates, signs and collects payment on behalf of the parent company, the tax authority may treat this as business activity, triggering unexpected tax obligations.
- Setting charter capital by gut feeling. Capital that is too low forces an early capital increase and license amendment; capital that is too high creates pressure to contribute in full within 90 days.
- Acquiring shares without a tax review. Invalid purchase invoices, unresolved balances and salaries without insurance contributions all pass to the new owner.
FAQ
Must a foreign investor obtain an IRC before setting up a company?
When establishing a new business entity, a foreign investor usually obtains the IRC first and then registers for the ERC. Capital contributions or share acquisitions in an existing company follow a different procedure, which depends on the business line and ownership ratio.
Can a representative office be converted into a company?
An RO cannot be converted directly into a company. Typically the investor sets up a new company, then terminates the RO and finalizes the office's PIT.
Which form has the lowest accounting cost?
An RO usually has the lightest accounting workload because it does not trade. FDI entities additionally need audited financial statements and more returns; at ACCA Consulting VN, monthly accounting for an FDI entity starts from VND 640,000 with no transactions.
