The “expert abroad, working for a Vietnamese company through a screen” model raises three legal questions at once: does the expert need a Vietnamese work permit, is their income taxable for personal income tax in Vietnam, and does using remote experts create a tax permanent establishment for the foreign side. This article answers layer by layer: the work-permit regime attaches to working in Vietnam, so it does not reach a person who never enters Vietnam; but the tax and permanent-establishment layers are far more complex and depend on the contract structure.
Governing Instruments
Work permits: a regime attached to working in Vietnam
The work-permit regime under Decree 219/2025/ND-CP applies to foreign workers working in Vietnam — that is, present and performing work on Vietnamese territory for an employer in Vietnam. An expert located abroad, never entering Vietnam and performing all work remotely, is outside this regime: no work permit, no labour visa, and no foreign-labour usage reporting duty for the Vietnamese enterprise in that case. The boundary shifts the moment the expert enters Vietnam to work in person, even in short rotations — then the work-permit category, or a confirmation of non-applicability, must be considered before the expert starts working, together with temporary-residence declaration under Article 33 of Law 47/2014 for the stay.
The tax layer: income source decides, not merely where the chair sits
For personal income tax, the question is whether the income is Vietnam-source and whether the expert is a Vietnamese tax resident or non-resident. An expert with no presence in Vietnam is typically a non-resident; salary for work performed entirely outside Vietnamese territory is in principle not income from employment in Vietnam. But the payment structure changes the analysis: if the Vietnamese company pays the expert directly under an employment relationship with costs borne by the Vietnamese side, the tax authority may examine Vietnam-source character; if the expert is an employee of a foreign company and the Vietnamese company pays service fees to that company, the transaction becomes a cross-border service purchase — engaging foreign contractor tax and the foreign company permanent-establishment question. The double taxation agreement between Vietnam and the expert residence country (if any) is the final deciding instrument on employment-income taxing rights and the service-presence threshold creating a permanent establishment.
Application Analysis
Permanent establishment: the risk sits in the structure, not in a lone remote individual
A lone individual expert working remotely from abroad, by themselves, usually creates a permanent establishment for nobody: the Vietnamese company is already a Vietnamese taxpayer; and the foreign side (if the expert is an independent individual) has no enterprise to attach a permanent establishment to. The permanent-establishment risk arises when the expert is personnel of a foreign enterprise supplying services to the Vietnamese company: if that personnel is present in Vietnam providing services beyond the time threshold of the applicable tax treaty (a service permanent establishment), or a dependent agent in Vietnam habitually concludes contracts in the foreign enterprise name, the foreign enterprise is treated as having a Vietnamese permanent establishment and the profits attributable to it are taxable in Vietnam. Working fully remotely, without presence, keeps this risk low — but cumulative business trips within any 12-month window must be counted and tested against the specific treaty threshold.
Contract design: four allocation points
A remote-expert contract should settle four points: (1) the relationship nature — a service contract with an independent individual, a cross-border employment contract, or an inter-company service contract with the foreign enterprise; each pulls a different tax and duty regime and must match the working reality (labelling an employment substance as services is a reclassification risk); (2) tax-duty allocation — who withholds, who finalises, gross-up or net mechanics, and the duty to supply tax-residence certificates for treaty application; (3) insurance — an expert not working in Vietnam is outside Vietnamese compulsory social and health insurance, but the contract should record their home-country insurance status and allocate medical/incident costs; (4) data and intellectual property — the expert accessing Vietnamese company systems from abroad engages personal-data protection duties under Law 91/2025 (cross-border access to personal data) plus work-product ownership and confidentiality clauses.
Recommended Actions
- Confirm the expert never enters to work: no work permit; if trips in occur, assess the permit/exemption category before each trip.
- Classify the relationship (individual services / cross-border employment / inter-company services) and keep contract, payment and reality consistent.
- Check the double taxation agreement with the expert residence country on employment income and service-PE thresholds.
- Count cumulative presence days in Vietnam of the foreign side personnel in every 12-month window.
- Settle in the contract: tax withholding allocation, tax-residence certificates, home-country insurance, data protection and IP.
Frequently Asked Questions
Does a foreign expert abroad working remotely for a Vietnamese company need a work permit?
No. The work-permit regime under Decree 219/2025/ND-CP applies to foreign workers working in Vietnam. An expert who stays abroad, never enters Vietnam and works entirely remotely is outside this regime. Only when the expert enters Vietnam to work in person — even in short rotations — must the enterprise consider the work-permit category or a confirmation of non-applicability before they start working.
How is a remote expert’s income taxed for personal income tax in Vietnam?
It depends on income source and residence status: an expert with no presence in Vietnam is a non-resident, and salary for work performed entirely outside Vietnam is in principle not Vietnamese employment income. But if the Vietnamese company pays directly under an employment relationship with costs borne by the Vietnamese side, or the substance is a service purchase from a foreign enterprise (engaging contractor tax), the analysis changes. The double taxation agreement with the expert residence country is the final deciding basis.
Does using remote experts create a tax permanent establishment for the foreign side?
A lone expert working fully remotely, by themselves, usually creates no permanent establishment. Risk arises when the expert is personnel of a foreign enterprise: presence providing services in Vietnam beyond the tax treaty time threshold (service PE), or a dependent agent in Vietnam habitually contracting in that enterprise name. Enterprises should count cumulative presence days and test them against the applicable treaty.
How should a remote-expert contract be designed to allocate tax and insurance duties?
Settle four points: the relationship nature (independent services, cross-border employment or inter-company services) consistent with reality; tax allocation — withholding, finalisation, and tax-residence certificates for treaty relief; insurance — an expert outside Vietnam is outside Vietnamese compulsory social/health insurance, so record home-country cover and cost allocation; and personal-data, confidentiality and IP clauses for system access from abroad.
