Normal enforcement against false self-employment has resumed in the Netherlands. Businesses may face payroll tax corrections when contractor work functions as employment. A proposed legal presumption for lower hourly rates could put the burden of proof on the client.
Why this matters
A paid contractor invoice sits in the accounts as an external cost. A later payroll tax assessment creates a liability for work completed months earlier. Check the daily work: hours, supervision, substitution, commercial risk, and integration. Corrections generally reach back to January 1, 2025. Intentional false self-employment or ignored instructions can extend that period. Culpability penalties may apply from 2026. Default penalties will not be imposed that year. The proposed €38 presumption could shift proof to the client.
Example
A technical firm hires a specialist for a six-month customer project. At first, the specialist chooses the method and schedule and works for other clients. Three months later, a manager sets daily priorities and requires fixed availability. The specialist attends staff meetings and fills an ongoing role. The contract and invoices have not changed, but the working relationship has. The firm may face payroll tax exposure absent from its cash and margin planning.
XTROVERSO tips
- List recurring contractors. Start with people who work fixed hours, perform core tasks, or have been engaged for a long period.
- Match the file to the working day. Check the contract, invoices, schedule, supervision, substitution rights, tools, and commercial risk.
- Review changes during an assignment. Fixed availability, recurring duties, and tighter management can turn a project into a staff role.
- Calculate possible cash exposure. Estimate payroll tax payable from January 1, 2025. Check when the business could fund it.
- Test customer margins. Review pricing where contractor capacity may move to payroll, agency work, or a clearer supplier assignment.
- Set an owner and review date. Record who approves contractor hiring, where evidence is kept, and when each material relationship needs another review.
