Overseas Vietnamese investing back in Vietnam enjoy a dual advantage: understanding the domestic market, language, and relationships like a Vietnamese, while accessing capital, technology, and international networks like a foreign investor. But this very “dual” position raises the first and most important legal question: does an overseas Vietnamese invest as a domestic or as a foreign investor? The answer — depending on nationality — determines the entire procedure: whether an Investment Registration Certificate (IRC) is needed, whether market-access restrictions apply, and which investment incentives are available.
This article systematises the investment legal framework for overseas Vietnamese: from determining investor status, investment forms, IRC/ERC procedures, incentives, and tax, to bridging into the foreign investment (FDI) regime when overseas Vietnamese choose — or are required — to invest as foreign investors.
Quick summary: overseas Vietnamese investing and doing business
| First question | Investor status: still holding Vietnamese nationality → like a domestic investor; holding foreign nationality (no longer Vietnamese) → like a foreign investor. |
|---|---|
| Common forms | Establishing an economic organisation (IRC + ERC), contributing capital/buying shares or capital contributions (M&A), contractual cooperation. |
| Core procedures | IRC (Investment Registration Certificate) → ERC (Enterprise Registration Certificate) → sub-licences by business line. |
| FDI bridge | When investing as a foreign investor, the full FDI framework applies: market-access conditions, capital contribution approvals, investment incentives. |
1. Investor status: domestic or foreign?
The Law on Investment distinguishes domestic and foreign investors based on nationality and place of establishment. The general principle: individuals still holding Vietnamese nationality invest in Vietnam as domestic investors — enterprise establishment procedures as for domestic citizens, no IRC required, no foreign-investor market-access restrictions. Individuals holding foreign nationality (including overseas Vietnamese who have renounced Vietnamese nationality) invest as foreign investors — they must follow the investment procedures applicable to foreign investors.
For dual nationals (both Vietnamese and foreign), determining the applicable status requires examining the law in force at the time of investment — in practice, it is usually based on the nationality the investor chooses to use in the file. This is a point a lawyer should determine from the outset, because choosing the wrong status leads to redoing the entire procedure chain.
2. Investment forms under the Law on Investment
The Law on Investment 143/2025/QH15 (passed on 11/12/2025, effective from 01/3/2026, replacing the Law on Investment 61/2020/QH14) provides investment forms including: establishing economic organisations; contributing capital, buying shares or capital contributions; implementing investment projects; and investing under contractual forms. For individual overseas Vietnamese investors, the two most common forms are establishing a new company (building their own brand and model) and contributing capital/buying shares in an existing enterprise (leveraging the platform, licences, and market).
3. Company establishment: IRC and ERC
For overseas Vietnamese investing as foreign investors, establishing an economic organisation linked to an investment project involves two steps: obtaining the IRC — Investment Registration Certificate at the investment registration authority (the Industrial Park/Economic Zone Management Board or the Department of Finance, by decentralisation), then obtaining the ERC — Enterprise Registration Certificate at the business registration authority. The IRC file includes the investment project proposal, proof of financial capacity, land-use needs, and the investor’s legal documents (legalised if issued abroad).
For overseas Vietnamese with domestic-investor status, the procedure is much simpler: only enterprise registration (ERC) is needed as for domestic citizens, no IRC — unless the project requires investment policy approval. After the ERC come: seal engraving, bank account opening, tax registration, and sub-licences if the business lines are conditional.
4. Capital contributions, share purchases (M&A)
Foreign investors (including overseas Vietnamese holding foreign nationality) contributing capital, buying shares or capital contributions in Vietnamese economic organisations must complete the procedure for registering capital contributions, share or capital-contribution purchases at the investment registration authority in cases prescribed by law — particularly when the transaction increases the foreign investor’s ownership ratio in an enterprise operating in business lines subject to market-access conditions, or results in the foreign investor holding over 50% of charter capital.
Practical M&A with overseas Vietnamese capital requires additional review: whether the target’s charter restricts transfers; whether the enterprise holds sub-licences tied to its ownership structure; the transferor’s tax obligations (income tax on capital transfers: 20% on income for organisations, 0.1% on securities transfer prices…); and payment mechanisms through banks. See the full FDI procedure framework at FDI company formation in Vietnam.
5. Market-access conditions and conditional business lines
Foreign investors — including overseas Vietnamese investing in this capacity — must comply with market-access conditions: some business lines are prohibited or restricted for foreign investors (lists under international commitments and domestic law), some require maximum ownership ratios, investment forms, or Vietnamese partners. The list of conditional business lines is prescribed in the Appendix to the Law on Investment.
Overseas Vietnamese have a special advantage here: market understanding helps them spot “sensitive” lines early (telecommunications, education, logistics, distribution…), and domestic networks help find Vietnamese partners when joint ventures are needed. Conversely, the mindset of “I’m Vietnamese so surely no restrictions apply” is the most common mistake — once investing as a foreign investor, all market-access restrictions apply in full.
6. Investment incentives: tax, land, procedures
Investment projects of overseas Vietnamese (as foreign investors) may enjoy investment incentives like any other FDI project if conditions are met: corporate income tax incentives (preferential rates, time-limited exemptions/reductions), exemptions or reductions of land rental and land-use fees, and procedural support. Eligibility conditions are usually tied to the investment location (difficult areas, industrial parks, economic zones), incentivised sectors (high technology, renewable energy, infrastructure…), or capital scale.
A point to note: incentives are not automatic — they must be registered and recorded in the IRC or the approval document. Many investors miss incentives simply by not proposing them at the IRC-file stage. For overseas Vietnamese investing with domestic status, incentives apply under the general policies for domestic enterprises (CIT incentives by location and sector under the CIT Law).
7. Investment capital, profits, and outward remittance
Foreign investors transfer investment capital into Vietnam through a direct investment capital account (DICA) opened at a licensed commercial bank — all receipts and payments relating to direct investment activities must go through this account. This is a major difference from personal capital flows and a mandatory foreign-exchange management requirement.
After-tax profits and capital-transfer proceeds may be remitted abroad after fulfilling financial obligations in Vietnam, through the banking system with documents proving the source of funds. The principle is consistent with personal asset management: every capital flow must go through banks with complete documentation from day one — capital taking “roundabout routes” will get stuck when remitting profits abroad.
8. Taxes on investment and business activities
Enterprises with overseas Vietnamese capital bear full tax obligations like ordinary enterprises: corporate income tax (the standard 20% rate, incentives by project), value-added tax, personal income tax (withholding at source on salaries and dividends paid to individuals), foreign contractor tax on payments abroad, and other taxes by activity. Transactions with affiliated companies abroad are also subject to transfer pricing rules — transfer pricing documentation must be prepared.
Overseas Vietnamese who are simultaneously individuals with personal assets in Vietnam (houses and land — see Overseas Vietnamese buying houses and land) need to strictly separate personal and corporate finances — mixing the two cash flows is a common cause of tax arrears and internal disputes. See also FDI tax advisory.
9. Labour and overseas Vietnamese as legal representatives
Overseas Vietnamese directly operating enterprises should note their labour status: persons holding foreign nationality working in Vietnam must have a work permit (except exempted cases) — even as owners or capital contributors. Persons still holding Vietnamese nationality are not subject to this requirement.
The legal representative position may be held by an overseas Vietnamese; residence information must be clearly registered and the legal liabilities attached to the position noted. If not habitually resident in Vietnam, an additional resident representative should be arranged in the country to keep operations and signing uninterrupted.
10. Land and premises for investment projects
Investment projects needing land must conform to land-use planning and plans and complete land allocation or lease procedures under the Land Law 2024. Foreign investors are leased land by the State (one-time or annual payment), and may not be allocated land with land-use fees like domestic organisations — a difference to factor into project financial models.
The common practice is leasing land in industrial parks — fast, ready infrastructure, centralised procedures through the Management Board. Whichever form is chosen, due diligence is needed: the remaining land-lease term, whether the land-use purpose suits the business line, and whether costs have been fully accounted for.
11. The FDI bridge: when to invest as a foreign investor?
There are cases where overseas Vietnamese should invest as foreign investors: when seeking investment incentives for FDI projects; when the capital structure involves other foreign investors; when seeking investment protection under bilateral investment treaties (BITs) Vietnam has signed; or when they simply no longer hold Vietnamese nationality and have no other choice.
In that case, the full FDI framework applies: see details at FDI company formation in Vietnam — from IRC and market-access conditions to periodic investment reporting obligations. Overseas Vietnamese are in a uniquely advantageous position to act as a “bridge”: understanding both the international legal language of foreign partners and operational realities in Vietnam — which is precisely the role FLAT LAW FIRM often plays for investment structures involving overseas Vietnamese.
12. Recommended roadmap for overseas Vietnamese starting to invest
A practical roadmap includes: (1) determining investor status (nationality) and the target investment model; (2) checking market-access conditions of the intended business lines; (3) choosing the form (new establishment or M&A) and capital structure; (4) preparing investor documents (legalising foreign documents); (5) completing IRC (if needed) → ERC → sub-licences; (6) opening a DICA, transferring capital, deploying the project; (7) establishing accounting, tax, and reporting systems from day one.
FLAT LAW FIRM accompanies overseas Vietnamese throughout the roadmap: determining investment status, appraising projects and target enterprises (M&A), completing IRC/ERC and sub-licences, advising on tax and transfer pricing, drafting contracts and structuring transactions.

FAQs
Which regime applies to dual-nationality overseas Vietnamese?
It depends on the nationality used in the investment file and the regulations in force at the time. Using Vietnamese nationality applies the domestic-investor regime; using foreign nationality applies the foreign-investor framework (IRC required, market-access conditions). Determine this clearly from the start, as choosing wrongly means redoing the entire procedure.
Does establishing a 100% overseas-Vietnamese-owned company (foreign nationality) require an IRC?
It is no longer mandatory in the old sequence. Under the Law on Investment 143/2025/QH15 (effective from 01/3/2026), foreign investors may establish an economic organisation to implement an investment project before completing the IRC issuance procedure — provided market-access requirements are met at the time of establishment — and then complete the IRC procedure within the time limit under the implementing guidance. This is an important new point compared with the previous 2020 Law on Investment (which required an IRC before enterprise/ERC registration). As detailed guidance documents are being issued, the specific procedural sequence should be determined by a lawyer under the regulations in force at the time.
Does buying shares in a Vietnamese company require approval?
In cases prescribed by law — particularly when the transaction increases the foreign investor’s ownership ratio in an enterprise operating in business lines subject to market-access conditions — the capital contribution/share purchase must be registered at the investment registration authority and may only proceed after approval.
Are profits remitted abroad taxed?
Profits already subject to CIT in Vietnam are not subject to additional CIT when remitted abroad; however, dividends paid to individuals are subject to PIT withholding at source. Bank remittance files must evidence fulfilment of tax obligations.
Can overseas Vietnamese projects enjoy tax incentives?
Possibly, if investment incentive conditions are met (location, sector, scale) — incentives must be proposed and recorded in the IRC or approval document from the start; they do not arise automatically. Overseas Vietnamese investing with domestic status enjoy incentives under the general policies for domestic enterprises.
