Tax Confidentiality in the Netherlands: Why Small Business Owners Should Care

The quiet protection behind your tax return

If you're a small business owner who does their taxes properly and I assume you are, you rely on a basic principle: the information you share with the Dutch Tax Authority stays between you and them.

That principle is called tax confidentiality, and it’s codified in Article 67 of the Dutch General Tax Act (AWR).

Sounds technical? Maybe. But this article is one of the few legal shields protecting micro and small companies from political exposure, public misinterpretation, or having their financials used as political ammunition.

So, what does Parliament want?

During discussions of the 2025 Tax Plan, some members of the House of Representatives asked whether this confidentiality could be loosened, especially in cases related to tax avoidance. The idea was that more transparency might help restore public trust in the tax system.

A noble thought, on paper. But here's the problem: if your privacy becomes a negotiation tool, you're the first to feel it.

Trust is a two-way street

The Dutch Tax Authority depends on honest disclosure. But that trust vanishes quickly if entrepreneurs start fearing that their information could suddenly become public.

And let’s be clear: small business owners don’t have legal teams to manage reputational damage. One leak, one poorly contextualized fact, and your company could end up in a headline, not because you did anything wrong, but because nuance doesn't trend online.

What has the government decided?

In short: no change to the law.

The Secretary of State firmly rejected any suggestion to expand public access to individual tax data. Here’s why:

• The privacy of taxpayers and the overall interest of the state in maintaining trust and compliance still outweigh Parliament’s desire for transparency.
• Even in high-profile cases, think media scandals or suspected avoidance, the default remains confidentiality.
• Exceptions can be made only in rare, unforeseen cases, and only after a case-by-case legal assessment.

Even when Parliament requests specific information, it’s often shared in confidential briefings only, and cannot be publicly debated unless the information is generalized.

Why does this matter to you?

Because fiscal peace of mind is not a luxury, it’s oxygen for entrepreneurs.

Because in a small business, your reputation is your credit line.

And because tax confidentiality isn’t about hiding, it’s about operating without fear of political or social backlash when you’ve done nothing wrong.

So, what should you do?

Nothing, yet. But stay informed.

Because if one day, “public interest” becomes an excuse to dismantle your right to privacy, the burden will fall on you, not on the ones debating transparency from behind government desks.
