Permanent establishment risk in Vietnam

Does using an EOR create a permanent establishment in Vietnam?

Not by itself — but it does not remove the risk either. Engaging staff through a Vietnamese EOR means a licensed local entity is the legal employer, which keeps the arrangement as ordinary local employment and is helpful.1 It does not automatically prevent the foreign client from being treated as having a taxable “permanent establishment” (PE) in Vietnam. If the worker habitually negotiates or concludes contracts that bind the overseas company, or the facts show that company is really carrying on business here, the tax authority can assert a PE and corporate-tax exposure, subject to any applicable double-tax treaty. Since 1 July 2026 it also looks harder at economic substance. This remains a fact- and treaty-specific grey area as of October 2026, so take Vietnamese tax advice and never assume an EOR eliminates PE risk.12

This page explains the mechanism honestly: what a PE is, the dependent-agent trigger that matters most for hiring, what it costs in tax, and how a treaty can (or cannot) help. It sits under our guide to whether an EOR is legal in Vietnam and who the legal employer is, and it pairs with the role-level view in hiring sales reps and country managers in Vietnam and the pre-entity scenario in the China+1 manufacturing guide.

What is a permanent establishment in Vietnam?

A permanent establishment is a taxable business presence in Vietnam through which a foreign enterprise's Vietnam-source business profits become taxable. Vietnamese corporate-income-tax law, read with the permanent-establishment article of any applicable double-tax treaty, recognises three broad forms. Where one exists, Vietnam can tax the profits attributable to it.16

How can a permanent establishment arise through an EOR hire?

The form that matters most for hiring is the dependent-agent PE. It can arise where a person in Vietnam habitually concludes contracts, or habitually negotiates and plays the principal role leading to the conclusion of contracts, in the name of or binding on a foreign enterprise — and is not a genuinely independent agent acting in the ordinary course of its own business.1 This is the key risk where in-country staff, including workers engaged through an EOR, do more than back-office or delivery work and instead commit the offshore company to its customers. Where a dependent-agent PE is found, the tax authority can treat the foreign principal as doing business in Vietnam and tax the profits attributable to that agent.12

Note that the risk can extend to people who are not formal employees: the same test can reach a contractor who is, in substance, acting for the foreign company. That overlaps with reclassification exposure — see the risk of treating an employee as a contractor in Vietnam — and with the separate question of co-employment, where both the EOR and the client direct the worker.

Which roles are most at risk?

Risk turns on function, not job title. The highest-exposure roles are the ones whose job is to win and commit business: sales representatives, business-development staff and country managers who negotiate terms, agree prices or sign off deals on behalf of the overseas company. A software engineer, a support agent or an operations hire who delivers a service under the legal employer's direction is a very different proposition from a salesperson who habitually closes contracts for the foreign principal.1

Because the sales role is where this bites hardest, the role-level playbook lives on its own page. If you are hiring into revenue-facing roles, read how to hire sales reps in Vietnam without creating a tax presence alongside this mechanism guide.

Why doesn't an EOR automatically solve permanent-establishment risk?

It is tempting to read “the EOR is the legal employer” as “the foreign client has no presence in Vietnam.” The two are not the same question. Employment law asks who the legal employer is; a licensed Vietnamese entity employing the worker and invoicing under a business-to-business agreement answers that cleanly, and it is how most EOR services in Vietnam are structured.1 Permanent establishment is a tax question, decided under corporate-income-tax law and the relevant treaty, and it looks through the employment label to what is actually happening.1

So a PE can still arise even with a clean EOR structure if the in-country worker habitually binds the offshore company, or if the overall facts show that company is carrying on its business in Vietnam. Post-Circular 95/2026, the authority can also test the real functions, assets, personnel, control and commercial purpose rather than the paperwork, so a thin structure with no economic substance is more exposed than before.2 Any provider that promises an EOR “removes” or “eliminates” PE risk is overstating the position; the honest answer, as of October 2026, is that an EOR helps but does not decide it.1

What does a permanent establishment cost in tax?

When a foreign company earns income from Vietnam it is usually taxed through Foreign Contractor Tax (FCT) under Circular 103/2014/TT-BTC, which has a corporate-income-tax (CIT) component and a value-added-tax (VAT) component. A treaty can relieve only the CIT part — and only if the company has no PE in Vietnam. Once a PE exists, that treaty shield falls away and the profits linked to the PE are taxable here; the VAT part is always due under domestic rules and is never relieved by a treaty.51

How do treaties and tie-breakers interact with a Vietnam PE?

Vietnam has signed double-taxation-avoidance agreements with more than 80 countries and territories, mostly based on the OECD model, and from 1 July 2026 applies them under Circular 95/2026/TT-BTC.32 Where a treaty applies, Vietnam may tax a foreign enterprise's business profits only if it has a PE in Vietnam as defined by that treaty's PE article — the “no PE, no business-profits tax” rule — and only the profits attributable to the PE. For an individual resident in two countries, treaties use tie-breaker tests (typically permanent home, then centre of vital interests, habitual abode and nationality) to decide which country taxes. None of this is automatic: relief must be claimed with a tax-residency certificate and supporting substance evidence, within a three-year window.21

The large exception is the United States. The US and Vietnam signed an income-tax treaty on 7 July 2015 and Vietnam ratified it, but the US Senate never did, so it has never entered into force; there is still no operative US–Vietnam tax treaty as of October 2026.78 That means the treaty machinery above is simply not available to US residents — a point we cover in depth, rather than restate here, in Vietnam's double-tax treaties and the US treaty gap and in what this means for US companies hiring in Vietnam.

How do I reduce permanent-establishment risk when hiring in Vietnam?

You reduce the risk by controlling what the in-country person does and where contracting authority sits — not by relying on any label. Because a dependent-agent PE turns on habitually binding the foreign company, the practical safeguards all push commitment offshore and keep the Vietnam role to support and delivery.1

• Keep contract authority offshore. Final negotiation, pricing sign-off and signature for customer contracts should rest with the overseas company, not the Vietnam-based worker.1
• Scope the role to support or delivery. Define the job around implementation, account support, engineering or operations rather than closing deals, and make sure the day-to-day reality matches the job description.1
• Keep day-to-day direction with the legal employer. Letting the overseas client run the worker like its own staff also feeds the separate co-employment argument, so route routine direction through the EOR as legal employer.1
• Build real substance where you claim treaty relief. Since Circular 95/2026 the authority tests functions, assets and purpose, so a treaty position needs genuine substance behind it, claimed with the right dossier.2
• Take Vietnamese tax advice on the specific facts. PE is decided case by case; a short review before you hire a revenue-facing role is cheaper than an FCT assessment after the fact.1

How EOR Vietnam handles permanent-establishment risk

EOR Vietnam is a Vietnam-focused employer of record. We hire your worker through a licensed Vietnam-registered employing entity on a standard labour contract — running payroll, withholding personal income tax and paying social, health and unemployment insurance as the legal employer — and invoice you under a business-to-business service agreement.1 That structure answers the employment question cleanly, and we say plainly that it does not, on its own, decide the tax question of permanent establishment.1

In practice that means we scope each role with you, keep the Vietnam-based worker's remit to support and delivery where that is the intent, keep day-to-day direction with us as legal employer, and flag in writing when a role looks revenue-facing enough to warrant your own tax advice. We do not claim to remove PE risk, and we will tell you when a question belongs with a tax adviser rather than an EOR. If you would rather weigh the model as a whole, read the benefits of using an EOR in Vietnam.

Our service fee is a flat US$149 per employee per month for Vietnamese nationals — the same fee regardless of salary, seniority, role or headcount, as of October 2026; it is not a percentage of payroll. Foreign hires who need a Vietnamese work permit are quoted separately, because the work-permit, visa and residence handling differs case by case — see work permits for foreign hires. There are no setup, onboarding, offboarding, contract or payslip fees, and no hidden fees. A security deposit equal to two months of the employee's employment cost — gross salary plus the statutory employer contributions — is held for the engagement and returned at the end, less any unpaid amounts. Everything else — gross salary, the roughly 23.5% statutory employer contributions, and any statutory or agreed employment payments — is passed through at cost; the full EOR Vietnam cost breakdown sets out how those parts add up.

This mechanism guide sits alongside the rest of our Vietnam employer guides, which work through the payroll, tax and compliance detail behind a cross-border Vietnam hire.
