Buying into or contributing capital to an operating Vietnamese enterprise (M&A) is the fastest route for foreign investors to enter the market — far faster than licensing a new project from scratch. But that speed comes with a perception trap: quite a few investors think it is “just a share sale”, sign the agreement, transfer the money and be done, while Vietnamese law sets two separate procedural layers for this transaction, plus market-access barriers and foreign ownership caps.
The core difference between M&A and greenfield setup is that the investor “inherits” the target company’s entire legal past: does the charter restrict transfers, has the charter capital been fully contributed, are there simmering internal disputes, what about the transferor’s tax obligations. Skipping this review, the investor may buy a company that looks clean on the licence but is full of risks inside.
This article analyses the full legal framework for capital contribution, share purchase and capital-contribution purchase by foreign investors in Vietnam: from notification procedures with the investment registration authority, change registration with the business registration authority, to notes on payment, charter and due diligence. The content is for general reference; each transaction needs specific review by a lawyer.

The two administrative layers of an M&A transaction
The first legal issue of a foreign-related M&A transaction is the two administrative procedural layers that many investors only know one of. The first layer is the notification procedure with the investment registration authority when the capital contribution, share purchase or capital-contribution purchase falls into a notifiable case. The second layer is the procedure for registering changes of members/shareholders with the business registration authority to record the new owners. Missing either layer leaves the transaction legally incomplete: without notification, the conditions to complete are not met; without change registration, the new investor is not recorded on the licence.
Unlike greenfield setup — where the investor must obtain an Investment Registration Certificate (IRC) for the project — ordinary M&A transactions do not create a new investment project and so do not need a new IRC. But this boundary is not always clear: if after the M&A the investor deploys an additional new investment project, an IRC must still be obtained for that project.
When notification to the investment registration authority is required
The notification obligation typically arises when the transaction increases the foreign investor’s ownership ratio in a business organisation operating in business lines with market-access conditions. This is the “gate” deciding whether the transaction may be completed: the investment registration authority appraises whether the post-transaction ownership ratio exceeds the foreign ownership cap of the business line, and whether the investor meets the sector conditions.
This check must be done before signing the sale agreement. A signed transaction that cannot complete procedures because it exceeds the ownership cap pushes both sides into renegotiation with one side already “locked in” — renegotiation costs are always far more expensive than upfront checking. For public companies, additionally check the remaining “foreign room” in the charter before price negotiation.
The notification file comprises the notification document with evidence that the investor meets the market-access conditions of the business line. Complete payment only after receiving the investment registration authority’s written approval — this is the iron discipline of every notifiable transaction.
Minimum due diligence before signing
Three contents that cannot be skipped when reviewing the target company:
- Company charter: any clauses restricting transfers, pre-emptive rights of existing members/shareholders? Many LLCs require a member wishing to transfer to offer to the remaining members first, or to obtain the Members’ Council’s approval. A transaction “dodging” the charter risks being declared void when disputed.
- Capital contribution status: has the charter capital been fully contributed? The buyer may “inherit” the transferor’s outstanding capital contribution obligation — a point often missed because it does not appear on the licence.
- Disputes and hidden liabilities: internal disputes, tax debts, guarantees, pending lawsuits, major contracts with change-of-control clauses. A concise but well-targeted review report is far cheaper than the cost of handling post-M&A disputes.
Also collect: the enterprise registration certificate, recent years’ financial statements, the member/shareholder register, and the target company’s list of sub-licences — because some licences attach to the old owner and may need to be redone after the ownership change.
Drafting the sale agreement: the decisive clauses
The share/capital-contribution sale agreement (SPA) in foreign-related transactions must contain the following clauses:
- Conditions precedent: the transaction completes only upon the investment registration authority’s written approval (for notifiable cases). Without this clause, the investor may be bound to pay while procedures are unfinished.
- Seller’s representations & warranties: the seller warrants the company’s legal status, completeness of capital contributions, no undisclosed disputes/hidden debts — with an indemnity mechanism when warranties prove false.
- Price adjustment mechanism: for multi-instalment deferred payments or post-audit price adjustments (earn-out), clearly prescribe the formula and the data-lock date.
- Transaction tax: clearly allocate which side bears income tax on the capital transfer, the withholding mechanism and who is responsible for filing. An unreasonable transfer price versus real value may be reassessed by the tax authority.
Payment through the capital account
Money for shares or capital contributions by foreign investors must go through the capital account opened at a commercial bank in Vietnam, under foreign exchange management regulations. “Off-circuit” payment — transferring straight from a personal account abroad into the seller’s personal account in Vietnam — violates regulations and leaves a chain of consequences: on the next transfer or when remitting profits abroad, the bank and the tax authority will require proof of a lawful inbound capital flow, which a “smuggled” payment transaction can never have.
Investors should open the capital account as soon as serious negotiations begin, and keep full vouchers of every money transfer — this is the file set reused throughout the investment lifecycle, from annual audits to exit.
Post-transaction change registration
After completing payment, the investor must register changes with the business registration authority: changing LLC members, changing shareholders and the legal representative (if any). Some investors sign, pay, and operate the company for months without registering changes — legally they are not yet recorded owners: they cannot sign valid resolutions, cannot fully exercise member/shareholder rights, and when an internal dispute arises the old seller is still the name on the licence.
Post-transaction completion also includes: amending and supplementing the charter; updating the member/shareholder register; reviewing sub-licences attached to the old owner; and putting the target company into the investor’s general compliance checklist (periodic reporting, tax obligations, work permits for foreigners…).
The four costliest mistakes in foreign-related M&A
- Signing and transferring money before approval: when the notification procedure is not approved (exceeding the ownership cap, not meeting sector conditions), the investor has paid but cannot become a lawful owner.
- Skipping the charter’s internal sequence: not offering to existing members or not obtaining the Members’ Council’s approval as the charter requires — the transaction risks being declared void.
- Paying through the wrong channel: not via the capital account — violating foreign exchange management and causing chain obstacles when remitting profits/capital abroad.
- Forgetting change registration: without registering with the business registration authority, one is not a recorded owner, even after paying in full.

FAQ
When must a foreign investor notify the investment registration authority when buying shares?
When the capital contribution, share purchase or capital-contribution purchase increases the foreign investor’s ownership ratio in a business organisation operating in business lines with market-access conditions, or falls into other notifiable cases under the Investment Law. Ordinary share purchases in companies outside conditional business lines may not need notification — but change registration with the business registration authority is still required.
Can foreign investors buy 100% of a Vietnamese company?
It depends on the business line. For business lines without restrictive conditions, foreign investors may own 100%. For business lines with market-access conditions, the ownership ratio may be capped at a certain ceiling under sector law and Vietnam’s international commitments. Check before signing the agreement.
Through which account must share purchase money be paid?
Through the foreign investor’s capital account opened at a commercial bank in Vietnam, under foreign exchange management regulations. Payment not via the capital account is a violation and will cause obstacles when remitting profits or capital abroad later.
What if the target company’s charter restricts transfers?
Follow exactly the internal sequence the charter prescribes — e.g. offering to existing members/shareholders first, or obtaining the Members’ Council’s/General Meeting of Shareholders’ approval. Skipping this sequence may render the transaction void when disputed.
What do conditions precedent in the SPA include?
At minimum: the investment registration authority’s written approval (if notifiable); completion of due diligence with acceptable results; no material adverse change to the target company before the completion date. Without this clause, the investor may be bound to pay while procedures are unfinished.
Which side bears income tax on the capital transfer?
In principle the transferor bears it, but the SPA should clearly prescribe the withholding mechanism and who is responsible for filing and paying tax to avoid disputes. An unreasonable transfer price may be reassessed by the tax authority.
Does buying shares require a new IRC?
Usually not — because no new investment project arises. The investor completes the notification procedure (if applicable) and enterprise change registration. However, if after the M&A the investor deploys a new investment project, an IRC must still be obtained for that project.
What should be done with the target company’s sub-licences after purchase?
Review all sub-licences: those attached to the old owner or old representative need amendment/re-issuance procedures; at the same time put the company into the investor’s periodic compliance checklist (investment reporting, tax, labour).
