Local payroll and social security compliance in Netherlands

The Netherlands is a professionally open market: keeping accounts or running payroll for third parties requires no qualification, no licence and no registration. Only the title of accountant and the signing of statutory audits are reserved. The quality of a Dutch partner is therefore assessed through voluntary signals, professional memberships and individual registration of payroll staff, rather than through any accreditation.

The country lies within the European Union and the European Economic Area, so an employee moving from France stays covered by the European coordination rules, evidenced by an A1 certificate. Pay is settled in euro and contractual documents are written in Dutch, even though English is widely used in international companies.

The most striking technical feature is the unification of withholding. Wage tax and employee insurance contributions are collected together by the tax administration under a single concept, so there is no Dutch equivalent of a separate social security body certificate. Due diligence therefore rests on evidence a firm chooses to supply rather than on any register.

Registering as an employer with the tax administration is enough for a foreign company that would rather not incorporate: it obtains a wage withholding number in the process. This route is common and works well, provided the accompanying reporting obligations are accepted.

Written contracts are the norm, and the employer must inform the employee in writing of the essential terms of the relationship. Check whether a sector collective agreement applies and whether an industry pension fund is compulsory for the activity: that affiliation, often discovered late, applies retroactively.

There remains the question of which Dutch sickness and accident arrangements fall to the employer. Continued payment of wages during sickness is the most disconcerting of them: it runs for a long period and comes with active reintegration duties, which makes it a financial exposure to be covered, often through insurance.

Payroll produces a single periodic return covering both tax and contributions, together with the corresponding payment. Ending an open-ended contract requires either administrative authorisation or a court decision depending on the grounds, and a transition payment is due in most cases. Check finally the tax regime applicable to employees recruited from abroad, whose conditions and duration have been revised more than once in recent years and should never be assumed from an older briefing note.

Continued payment of wages during sickness is the heaviest Dutch peculiarity for a foreign employer: its duration far exceeds European practice elsewhere, and it carries an active reintegration duty whose breach can extend the obligation further.

Terminating an open-ended contract is no more a matter for the employer alone: depending on the grounds, it runs either through the public employee insurance agency or through the courts. That duality surprises groups used to a single procedure.

Chain liability completes the picture. A Dutch principal can be held liable for the tax and social debts of its subcontractor, which explains the local importance of payment behaviour statements and the existence of a voluntary sector label based on periodic audits, valued whenever personnel are placed at a client's disposal. Cost in the Netherlands is driven by these three points far more than by headline contribution rates.
