Outsourcing payroll in 2026: costs, points of attention and when it pays off

Nothing damages an employee's trust faster than an error on their payslip. Yet doing payroll is a trade of its own: collective labour agreements, contributions and tax tables change constantly. Outsourcing your payroll removes that risk, but what does it cost and what should you watch for? This article gives the overview for 2026.

What does outsourcing your payroll involve?

When outsourcing your payroll or salary administration, a specialist takes care of the monthly pay run, the payslips, the payroll tax returns and the pension filings. Onboarding and offboarding, absence reports and questions about collective labour agreements and arrangements are often part of it too. You submit the changes, the rest is arranged, on time and in line with the applicable rules.

What does outsourcing payroll cost in 2026?

The price is usually built up from a base amount plus a rate per payslip. The more employees, the lower the rate per slip often is. The indicative amounts below apply to 2026 and vary by service provider and complexity (think of varying contracts, shift work or many changes).

Do it yourself or outsource: when does it become attractive?

With one or two employees and stable contracts, payroll is still manageable. But as soon as your workforce grows, contracts change or you have to deal with a collective labour agreement, the time and the risk of errors rise quickly. From around 8 to 10 employees, many entrepreneurs choose to hand payroll over, simply because the time and risk no longer outweigh the cost.

What to watch for when choosing a payroll office?

Which responsibilities remain with you as the employer?

• Submitting changes accurately and on time (joining, leaving, hours, adjustments).
• The ultimate responsibility for the accuracy of the data you submit.
• Employer decisions such as terms of employment and remuneration.
• Keeping your personnel records in order, even when the execution sits elsewhere.

How the switch works

1. 1

   Inventory

   You share your workforce, contracts and collective labour agreement; you receive a proposal with a fixed price.

2. 2

   Setup

   The office sets up the payroll administration and connects to the pension fund and the Tax Administration.

3. 3

   First pay run

   The first pay run is checked carefully before the payslips go out.

4. 4

   Ongoing

   From then on you submit the changes every month and the rest is arranged.
