What Most Companies Miss When Choosing EOR Solutions in Vietnam

Introduction

A company relocated a regional director to Ho Chi Minh City in March. They were confident their Employer of Record Vietnam had payroll fully handled. By October, the director had crossed into Vietnamese tax residency. Nobody noticed. The company’s withholding had been wrong for months.

That’s not a failure of the EOR model itself. It’s a failure to ask the right questions before signing. EOR solutions in Vietnam all promise compliance, payroll, and legal employment. What they don’t all deliver is the same attention to detail on the specific mechanics that trip companies up.

Stories like this rarely make it into a sales conversation, for obvious reasons. No provider leads with a story about a client who got burned. That means the burden of asking the right questions sits with the buyer. It has to happen before the contract is signed, not after.

A provider that handles payroll isn’t the same as a provider that tracks every threshold that changes your payroll obligations.

Most companies compare EOR solutions in Vietnam on price and turnaround time. Those are reasonable things to compare. They just aren’t the things that create real risk later. The risk sits in the details a sales call rarely covers. Those same details rarely show up in a comparison spreadsheet either.

This guide walks through four things companies routinely miss. Probation rules often don’t match what most companies expect. A tax residency shift can change everything for relocated staff. A severance allowance gap can survive even with an EOR in place. And there’s the basic question of whether the provider is actually who they say they are. Each of these sits below the surface of a standard sales conversation, which is exactly why they get missed.

What Are EOR Solutions in Vietnam?

EOR solutions in Vietnam allow a foreign company to hire staff without registering its own entity. The EOR is a locally registered employer that handles payroll, statutory insurance, and Labour Code compliance. Your company still directs the employee’s day-to-day work. The arrangement is legal for both Vietnamese and foreign staff, provided the EOR itself holds proper registration.

Most buyers understand this basic structure well. Where EOR solutions in Vietnam actually differ from each other is in execution, not in the structure itself. Two providers can describe themselves in identical terms during a sales call. They can still handle the same employee’s paperwork completely differently once the contract is signed.

Common Mistakes When Choosing an EOR in Vietnam

• Assuming the EOR’s Standard Probation Template Applies

Many companies assume probation works the same everywhere. A flat two or three months, negotiable, done. Vietnam doesn’t work that way.

Probation length is capped by role type under Article 25 of the Labour Code. Enterprise executives can have up to 180 days. Roles requiring a college degree or higher are capped at 60 days. Technical and vocational roles get 30 days. Everything else gets six working days. Each job also gets only one probation period, ever, with no second attempt allowed.

The salary rule catches people out too. Probation pay must be at least 85% of the role’s full salary. It can’t be set at whatever lower rate feels reasonable for a trial period.

Get either of these wrong and the exposure is real. Regulators can fine an employer VND 2 to 5 million for exceeding the permitted probation length. On top of that fine, the employer must backpay full salary for the excess period, not just the shortfall.

A generic template built for a different market won’t automatically catch this. Ask specifically whether your Employer of Record Vietnam provider maps probation length to the employee’s actual role classification. A one-size default is the wrong answer to that question.

Consider a software engineer hired on a standard three-month probation, a common default in many countries. Under Vietnamese law, that role likely falls into the 60-day college-degree category. That means the third month of a “standard” three-month probation is already unlawful. If the EOR’s system doesn’t flag role classification automatically, nobody catches the overrun until it’s already happened.

• Assuming Tax Withholding Stays the Same All Year

This is the mistake from the introduction, and it’s more common than it should be. Vietnam taxes people differently depending on how long they’ve been in the country. That status can change mid-year without anyone flagging it.

Anyone present in Vietnam for 183 days or more in a calendar year becomes a tax resident. Tax residents pay progressive rates from 5% to 35% on worldwide income. Below that threshold, they’re a non-resident, taxed at a flat 20% on Vietnam-sourced income only. A relocated manager who assumes they’ll stay non-resident all year can cross that line without realising it.

The financial gap isn’t small. A non-resident paying a flat 20% can suddenly owe considerably more once resident status kicks in. Progressive rates then apply to their full worldwide income, not just what they earn in Vietnam.

If the EOR isn’t actively tracking days in-country, nobody catches this in real time. The company only finds out at year-end finalisation. By then, the shortfall is already owed, often with interest attached.

Tax residency in Vietnam isn’t a one-time classification. It’s a running count that someone has to actually watch. Ask your provider directly how they track this for relocated staff. Find out exactly what happens the month someone crosses the 183-day mark.

This is also where the direction of travel matters. A company sending someone on a short assignment can plan around staying below 183 days, if that’s genuinely the intent. A company expecting the assignment to run indefinitely should plan for residency from the start. Treating it as a mid-year surprise is the wrong approach either way. Both plans only work if the EOR tracks the calendar closely enough to tell you which one you’re in.

One more factor compounds this. Personal deductions and dependent allowances only apply once residency is established. A late-year residency crossing can create a real cash flow gap between what was withheld and what’s actually owed. A provider tracking days properly can adjust withholding as the crossing approaches. That beats leaving the company to absorb a lump-sum shortfall at finalisation.

• Assuming Zero Severance Liability Because an EOR Is Involved

Since 2009, unemployment insurance has replaced severance allowance for most working time in Vietnam. Many companies read that fact once and stop there. They conclude severance simply doesn’t apply anymore. That’s not quite right.

Severance allowance still applies to any period not covered by unemployment insurance. Probation time is explicitly one of those periods. Say an employee spent 60 days on a probation contract before converting to a full labour contract. That stretch generates a small but real severance obligation under Article 46. It’s calculated separately from anything unemployment insurance covers.

The amounts involved are usually modest for a single employee. Across a growing headcount with regular probation-to-hire conversions, the miscalculation adds up over time. It’s also the kind of gap that surfaces during a labour dispute, not a routine audit. That timing makes it worse when it does appear. A former employee raising the issue after termination gives the company far less room to fix things quietly.

A provider who has actually built this into their termination calculations will mention it unprompted. An Employer of Record Vietnam that says severance is simply a non-issue hasn’t looked closely enough at their own numbers.

The calculation has its own quirks that are worth knowing. Severance is worked out as half a month’s average salary for each qualifying year, with the period excluded for prior unemployment insurance coverage and any fraction of a year rounded to the nearest six months. None of this is complicated math on its own. It becomes a real burden when a company converts probation hires to full contracts every month across a growing team. That’s especially true when nobody is tracking which slice of each employee’s tenure falls outside unemployment insurance coverage.

• Assuming Every EOR Is Actually a Registered Legal Employer

The EOR model only works because the provider is a genuine, locally registered entity. Some businesses assume any Employer of Record Vietnam provider automatically meets that bar. Some providers subcontract part of the arrangement to a local partner. The client company never interacts with that partner directly, and often doesn’t know it exists.

This matters because every obligation covered above sits with whoever the real legal employer is. Probation compliance, tax residency tracking, and severance calculation aren’t abstract responsibilities. They belong to a specific registered entity. If that entity is a subcontracted partner rather than the company you signed with, accountability gets harder to pin down. That’s exactly when something tends to go wrong.

Our related piece on entity setup versus EOR in Vietnam covers how this registration question shapes the broader decision. It’s worth reading before you weigh building your own entity against using a provider.

Ask directly whether the provider holds its own Enterprise Registration Certificate. Also ask whether any part of the employment relationship runs through a third party you haven’t met. A confident, specific answer is a good sign. A vague one is worth pushing on further. Our guide on hiring remote talent safely through an EOR in Vietnam also flags this as a first step before signing anything.

This isn’t a purely theoretical risk either. Subcontracting arrangements are common across the region precisely because building genuine local coverage in every market is expensive. A provider that’s honest about using a local partner is different from one that hides the structure. That’s true even if both claim to stand behind the outcome. The distinction matters most when something goes wrong, and you need to know exactly who is legally answerable for it.

What Do Most Companies Miss When Choosing EOR Solutions in Vietnam?

Most companies miss the mechanics that only surface after the relationship is already running. Probation caps are tied to role type, not a flat default. Tax residency shifts at 183 days, often unnoticed. Severance liability can survive in small pockets like probation periods. And the provider itself may not be the genuine registered employer it claims to be. None of these require a specialist to catch. They just require someone to ask the right question at the right time. That means before signing, not after something has already gone wrong.
