The Dutch Tax Prompt Library is a workbook, not an essay about artificial intelligence. It contains one hundred ready-made, fill-in prompts that you complete with your own case, ordered according to the work you actually do, from the tax memorandum to the notice of objection, from client correspondence to your own firm policy.

A language model predicts the most probable text, and a ruling that does not exist looks exactly like one that does. Without a fixed framework that forces every legal source back to its origin, the model produces convincing fiction. This library gives you that framework. Every prompt that touches on law obliges you to verify for yourself and marks every assertion that has not yet been checked as [TO VERIFY].

In that way the speed of the machine stays within the limits of your professional rules, and the judgement stays where it belongs, with you.

• One hundred fill-in prompts in eight categories: tax memoranda and advice, case law and legislative research, tax return support and explanatory notes, client communication and correspondence with the Belastingdienst (Dutch tax authority), objection and appeal, the WWFT (Dutch anti-money laundering act) and client file documentation, the defensible position and risk assessment, and firm policy, continuing professional education and AI accountability.
• The verification and anti-hallucination protocol as the centrepiece: no statutory provision, ECLI, ruling or citation leaves your office without a source check, with the fixed marking [TO VERIFY] for everything that has not yet been traced.
• With every prompt a purpose, a completion instruction and a safety note, so that you know what the prompt yields, how you fill it in and where you have to look for yourself.
• The WWFT and gatekeeper layer built in: no prompt bypasses client due diligence, no output runs ahead of your own assessment.
• Confidentiality and the GDPR safeguarded: no BSN (Dutch citizen service number) and no client data in public tools, with final responsibility resting with you and an audit trail in place.
• The Tax Quality and Safety Framework, with five diagrams and supporting illustrations, translating the tax duty of care and the defensible position into practical working arrangements.
• Grounded in real sources and real cases: the professional and disciplinary rules of RB and NOB (Dutch tax adviser associations), the WWFT and BFT supervision (the Dutch financial supervision office), the tax duty of care and the defensible position as developed in the case law of the Dutch Supreme Court (Hoge Raad), the GDPR and the EU AI Act.

This is for the tax professional who carries final responsibility, who signs, and who personally bears the risk. For the sole practitioner in tax advice who works without a second pair of eyes, and for the owner or partner of an SME tax advisory firm affiliated with RB or NOB (Dutch tax adviser associations). And for the senior tax adviser at an accountancy firm who guards the quality of the tax output.

In short, for the person who remains answerable under professional disciplinary law and under civil law once the signature is on the page. The model does not carry that risk. You do.

There is no shortage of free prompt lists in circulation. What they lack is precisely what a tax practice needs, namely a framework that makes the output safe. Here that framework is the core, not an appendix.

We do not sell hype and we promise no miracles. We separate fact from opinion, we refer only to real sources named in the text, and we build the safeguards into the prompt rather than into a disclaimer after the fact. That is necessary, because the ground is shifting. The adoption of AI in the tax sector has increased sharply, the guidance of the BFT (the Dutch financial supervision office) and gatekeeper supervision have been tightened as of 2026, and the EU AI Act imposes requirements. That is the field in which you advise.

And because we know where things go wrong, we have held ourselves to our own rule. This product contains no invented ECLI, no fictitious ruling and no fabricated citation. What we teach you to demand of the machine, we first demanded of ourselves.

You are welcome to look through the eight categories and the verification protocol first. You do not have to decide anything now. You judge for yourself whether it fits the way you sign.

The library is grounded in real, named sources rather than in general claims about technology: the professional and disciplinary rules of RB and NOB (Dutch tax adviser associations), the WWFT (Dutch anti-money laundering act) together with BFT supervision (the Dutch financial supervision office), the tax duty of care and the defensible position as developed in the case law of the Dutch Supreme Court (Hoge Raad), and the requirements arising from the GDPR and the EU AI Act. Every legal source named in the text is real and traceable, and the book contains no invented ECLI, no fictitious ruling and no fabricated citation.
