Wet DBA Compliance Netherlands: Is Your Contractor Agreement Still Enough?

Your contractor agreement hasn't changed in two years. But has the contractor's work stayed the same?

Maybe you hired someone in the Netherlands for a six-month project. Now they're still working with your team, attending meetings and handling regular business tasks.

The contract is the same. But their role has changed.

Under Wet DBA, this can become a problem. Dutch authorities look at how a contractor actually works, not just what the agreement says.

So, how do you know if your contractor is still truly independent? And what happens if the Dutch tax authority sees them as an employee?

Here's what your business needs to check before signing the next contract extension.

Can a contractor become a compliance risk without changing the agreement?

Yes. And it can happen slowly.

Let's say you hired an IT consultant in the Netherlands to complete one project.

They managed their own work and decided how to complete it.

The project went well, so you extended the contract.

A few months later, your manager started giving them regular tasks. They joined team meetings and began working more closely with your employees.

Nobody thought much about it because the work was getting done.

But now, the consultant works under your manager's direction. Does the original agreement still match how this person works?

That's what you need to check.

A long-term contractor isn't automatically an employee. But if the way they work has changed, their employment status may need another review.

This is one way contractor misclassification in the Netherlands can happen.

Does an approved Wet DBA model agreement protect your business?

Not always.

The Dutch tax authority, called the Belastingdienst, stopped approving new model agreements (modelovereenkomsten) on 6 September 2024.

Previously approved agreements that were valid at that time can generally be used until 31 December 2029, but only if the actual work follows the agreement.

For example, your agreement may say the contractor decides how to complete their tasks.

But what if your manager now decides their working hours and gives them daily instructions?

The agreement says one thing. The actual work shows something different.

An approved agreement alone cannot solve that difference.

So, when reviewing Wet DBA compliance in the Netherlands, don't just check whether you have the right document.

Check whether the document still matches the work.

How does the Dutch tax authority decide if someone is an employee?

The Belastingdienst looks at the full working relationship.

It considers nine factors from a Dutch Supreme Court decision in 2023, known as the Deliveroo judgment.

Some important questions include:

• Who decides how the work is done?

• How closely does the contractor work with your team?

• Does the contractor take business risks?

• Does the person run an independent business outside your company?

• How is the work paid for and organised?

No single answer decides whether someone is an employee.

For example, two contractors may have the same agreement.

One works independently on a fixed project. The other follows daily instructions from your manager and handles regular company tasks.

Their agreements are the same, but their working relationships are different.

That's why using the same contract for everyone doesn't mean everyone has the same level of risk.

What could Wet DBA enforcement in 2026 cost your business?

The Netherlands restarted enforcement against false self-employment (schijnzelfstandigheid) on 1 January 2025.

If a contractor is found to be an employee, your company may have to pay payroll taxes and other amounts linked to employment.

In 2026, serious-fault penalties may also apply in certain cases.

But here's what makes this more important for Finance teams.

Imagine your company has ten contractors in the Netherlands.

If several of them work like employees, you may have more than one contract to review.

You may also need to check unpaid taxes, employment costs and how those people should be hired going forward.

One incorrect working arrangement can be a problem. The same mistake across several contractors can become a much bigger cost.

That's why Wet DBA enforcement in 2026 matters when planning your workforce costs.

Who should check your contractors before their agreements are renewed?

Think about what happens when a contractor agreement ends.

Finance checks the payments. HR checks the contract. The hiring manager asks for an extension because the person is still needed.

But who checks whether the contractor is still working independently?

This is where companies can miss an important step.

Before renewing the agreement, ask the hiring manager what the contractor does today.

Then compare that with the original contract.

Has the person started handling regular business work? Does your manager now control how they complete their tasks? Do they still work as an independent business?

These questions can help you see which arrangements need a closer review.

They aren't a complete legal test. Dutch authorities consider the full relationship.

But asking them before renewal is better than finding the problem after a tax review.

What if your contractor should now be an employee?

First, don't assume every long-term contractor needs to become an employee.

Some contractors remain genuinely independent, even after working with one company for years.

But if the relationship looks more like employment, you need to review the available options.

You may need to change how the work is managed or move the person into an employment arrangement.

If your company doesn't have a Dutch entity, an Employer of Record (EOR) may be an option, where legally suitable.

At Dhi ADT, we help international businesses understand their contractor arrangements and identify where a closer compliance review is needed.

If employment is the right option, we can also help you explore EOR, payroll and local employment support.

Changing the arrangement now doesn't automatically remove earlier tax or employment obligations. Those need a separate review.

The goal is simple: make sure the way you hire someone matches how they actually work.

What should you do before your next contractor renewal?

Before signing another extension, ask one question:

If we hired this person today, would we still treat them as an independent contractor?

If you're not sure, review the working relationship before renewing the agreement.

Because a contract that worked when someone joined may no longer match the job they're doing today.

And finding that out early is better than discovering it during a Dutch tax review.

If you're unsure about your contractor arrangements in the Netherlands, book a compliance discussion with Dhi ADT.

We can help you understand what needs reviewing and which employment options may work for your business.
