Payroll service Vietnam: what a provider runs

Advertised prices, verified

How a payroll service in Vietnam runs each month

1. Registration and onboarding. The provider registers the employer and each new hire with the tax and social insurance authorities, collects the personal documents Vietnamese filings require, and sets up the employment records that every later calculation depends on. Errors here surface for years, so a provider's onboarding checklist is a good proxy for its overall discipline.
2. Monthly calculation and withholding. Each cycle the provider calculates gross-to-net for every employee: progressive personal income tax withheld at source, employee and employer shares of the mandatory social, health and unemployment insurance funds, and any taxable benefits. The employer contribution stack is a material cost on top of gross salary, so budget from the provider's full calculation rather than the salary figure alone.
3. Payment, payslips and filings. Net salaries are paid in Vietnamese dong, payslips are issued, and the withheld tax and insurance contributions are remitted to the authorities against the statutory deadlines. The provider files the periodic declarations and keeps the records an audit would request, which is most of what you are paying for.
4. Year-end finalisation. Vietnamese personal income tax runs on an annual settlement: at year end the provider reconciles each employee's withheld tax against the annual liability and handles the finalisation filings. A provider should be able to explain its finalisation process before you sign, because this is where monthly shortcuts become visible.

Payroll service or EOR: which one your situation needs

The deciding question is whether you have a Vietnamese legal entity. With one, a payroll service is the right product: you are the employer, it does the administration, and the fee is a per-employee processing charge. Without one, no payroll provider can register your hires, because there is no employer to register them under; the compliant route is an employer of record, whose Vietnamese entity holds the employment contracts, runs this same payroll machinery as the legal employer, and invoices you the salary, the employer costs and a flat monthly fee.

The two products are also different in what they carry. A payroll service executes calculations on your instructions and your liability stays your own. An EOR carries the legal employer obligations itself, which is why its fee is a multiple of a processing charge. The comparison table on this site shows verified monthly fees for vendors covering Vietnam, so the premium is a number you can check rather than guess.

What to check before choosing a provider

Ask how the provider keeps pace with statutory changes: contribution bases, insurance rates and the minimum wage levels that drive them are revised in Vietnam, and a provider still calculating on last year's figures produces confidently wrong payslips. Ask to see a sample gross-to-net calculation for a salary like the ones you will pay, with every employer-side line item shown, and ask which filings the provider signs and submits versus which it prepares for you to submit.

Check the operational details that decide whether the service is usable: cut-off dates for payroll changes, how off-cycle payments and terminations are handled, what language reports come in, and who answers when the tax office queries a filing. None of this is legal or tax advice; Vietnamese law and your contracts control, and figures should be verified against the authorities' current published rates at the time you rely on them.

Common questions

Can I use a Vietnam payroll service without a Vietnamese entity?

No. A payroll service administers payroll for a registered Vietnamese employer. Without an entity, an employer of record is the compliant route: its local entity employs your hires and runs the payroll as legal employer.

What does a Vietnam payroll service actually cost?

Payroll processing is priced per employee per month and sits well below EOR fees, which bundle the legal employer role. The verified vendor table on this site shows what EOR providers covering Vietnam advertise, so you can price both routes.

What contributions apply to employees in Vietnam?

Mandatory social insurance, health insurance and unemployment insurance, funded by employer and employee shares calculated on capped bases, plus progressive personal income tax withheld at source. Ask any provider for a current gross-to-net example rather than relying on generic figures, since bases and rates are revised.

How is year-end handled?

Through an annual personal income tax finalisation reconciling the year's withholding against the final liability, filed with the tax authority. A competent provider treats this as part of the service, not an extra.
