Post-merger integration Vietnam work determines whether the deal thesis survives. Vietnamese targets frequently come with informal practices in payroll, invoicing and related party dealings that were tolerable under private ownership and become a compliance exposure the moment an international group consolidates them.
This guide sets out the seven actions we run in the first hundred days after completion.
Post-Merger Integration Vietnam: Fix Governance First
Replace or reappoint the legal representative, update the charter to reflect the new reserved matters, and refresh the banking mandate and signatory list. Until this is done, the public record continues to show the previous management as able to bind the company.
The charter is the control document. A post-merger integration Vietnam plan that leaves the pre-deal charter in place typically discovers, six months later, that a local director can commit the company to matters the group intended to reserve.
Post-Merger Integration Vietnam: Re-Test Licences
Confirm which sub-licences name the owner or the legal representative and require reissue, and whether any registered business line has become conditional now that the company is foreign invested.
Tax and investment incentives require particular attention. Under Decree 96/2026/ND-CP a successor inherits incentives only where the conditions continue to be met, so an integration step that changes the activity or location can extinguish a benefit the price paid for.
Post-Merger Integration Vietnam: Harmonise Labour Terms
Review labour contracts, internal labour regulations, collective agreements and insurance registrations. Underdeclared salary for insurance purposes is the most frequent finding in Vietnamese targets and creates a quantifiable arrears exposure with interest.
Harmonising terms upward is straightforward; harmonising downward requires consent or a lawful restructuring process. Where redundancies are planned, the labour usage plan and consultation requirements apply. Our labour practice runs these processes.
Post-Merger Integration Vietnam: Align Tax and Transfer Pricing
The target becomes part of a multinational group on completion, which brings it within the transfer pricing regime under Decree 132/2020/ND-CP as amended by Decree 20/2025/ND-CP for the year of acquisition, not the following one.
Intercompany agreements for management services, royalties, procurement and funding should be signed before the first intercompany invoice, with benchmarking prepared contemporaneously. Retrofitting agreements after year end is the single most common transfer pricing audit finding in newly acquired Vietnamese subsidiaries. See our note on transfer pricing documentation.
Post-Merger Integration Vietnam: Unwind Legacy Related Party Arrangements
Vietnamese targets often carry loans from former owners, leases of premises owned by founders, and supply arrangements with affiliated companies on non-commercial terms. Each must be terminated, novated or repriced to arm’s length.
Founder leases deserve special attention because terminating them can leave the business without premises. Where the property is strategically important, acquiring it or securing a long lease should have been a condition of the deal rather than an integration task.
Post-Merger Integration Vietnam: Rebuild the Compliance Calendar
Set the calendar for corporate income tax provisional and finalisation filings, value added tax, personal income tax, insurance, statutory audit, annual investment reporting, foreign labour reporting and, where a representative office exists in the group, its annual operating report.
Under the two-tier local government structure, several filings now sit with different authorities than before. Confirming where each filing goes prevents a technically prepared return being submitted to the wrong office.
Post-Merger Integration Vietnam: Plan the Funding and Repatriation Path
Decide how the business will be funded going forward, register any offshore shareholder loan with the State Bank of Vietnam, and confirm that the direct investment capital account arrangements support the intended profit remittance.
Groups that leave this to the first dividend discover that historic capital contributions were misrouted and cannot be evidenced. Our guides to offshore loan registration and profit remittance set out the requirements.
Frequently Asked Questions
How long should integration take?
Governance and licences in thirty days, labour and tax alignment within ninety, funding structure within the first financial year.
Can the accounting period be changed?
Yes, with tax authority notification, and it is usually worth aligning to the group calendar in the first year.
Does the target keep its tax incentives?
Only where the conditions continue to be met. Verify before making operational changes.
What is the biggest hidden liability?
Underdeclared social insurance, followed by unsupported related party pricing. Both are quantifiable and both accrue interest.
