Dutch tax offence penalty: when should you instruct a tax lawyer?

1. Establish whether this is a proposal or an imposed penalty

Read the heading and substance of the letter first. A proposed penalty offering an opportunity to respond is different from a penalty already imposed. Record the tax, period, alleged conduct and response date. Also check whether the penalty appears on an assessment or in a separate decision.

Keep the envelope, digital message and attachments. Use the document’s exact terminology in your overview. This prevents an adviser relying on your summary from thinking that only discussions are needed when a formal objection period is already running. Asking for an explanation does not automatically stop a statutory deadline.

2. Distinguish procedural default, a tax offence and a tax adjustment

The Belastingdienst distinguishes a procedural default penalty, verzuimboete, from a tax offence penalty, vergrijpboete. The latter may relate, for example, to an intentionally incorrect or incomplete return. For an additional assessment following an earlier assessment, the Belastingdienst also identifies gross negligence as a possible basis. Do not conclude that every error in a return automatically justifies the same penalty.

Write down separately why you dispute the tax adjustment and why you dispute the penalty allegation. You might disagree about the tax treatment of an item while a separate assessment is needed of what you knew or did. A supported calculation alone does not answer every question about culpability.

3. Ask which specific facts support the allegation

Mentioning intent or gross negligence is not a complete account of the facts. Record which act, knowledge or omission the Belastingdienst identifies and which documents relate to it. Ask your lawyer how the evidential position for the penalty differs from that for the assessment. The Belastingdienst describes a separate burden of proof for penalties.

Organise both the return information and communications about how it was prepared. Include documents supplied, questions from your adviser and instructions you gave. Show what information was available and when. Do not fill gaps in your recollection with assumptions or retrospectively alter earlier correspondence.

4. Be precise about your adviser’s role

If an accountant or tax adviser prepared the return, the agreed work and the information you supplied matter. Bring the engagement letter and the specific questions and answers. Simply saying that the adviser handled everything does not fully describe your own involvement.

Have the facts relevant to the allegation assessed. An incorrect return and a possible failure in the adviser’s services are separate disputes. Discuss whether your interests and the previous adviser’s interests coincide before communicating about the penalty exclusively through that adviser. Independent legal assessment can help clarify these roles.

5. Protect the objection deadline and explain both disputes

For an objection to an imposed penalty, the Belastingdienst specifies six weeks from the date of the assessment carrying the penalty or the separate penalty decision. Check the instructions on your document. An objection to the assessment also covers the penalty on that assessment, according to the Belastingdienst. Nevertheless, explicitly explain why you disagree with the penalty.

If you cannot provide complete grounds in time, examine how to submit a timely objection and request permission to supplement it. Keep the exact text submitted and proof of dispatch or digital receipt. A proposed penalty may specify a different response period; do not treat the six-week period as automatically applying to every letter.

6. Discuss statements, evidence and any other proceedings

In penalty matters you do not have to answer questions about the infringement or the allegation of intent or gross negligence. Before questioning you, the Belastingdienst must inform you of this right to remain silent. Under the official explanation, you must still answer questions about tax due. The right to silence is therefore no general exemption from tax information duties. In a mixed interview, ask which questions concern taxation and which concern the penalty allegation. Discuss that distinction with your lawyer before giving a statement or signing a report.

If you also receive an invitation from the FIOD, police or a criminal procedure document, immediately inform your lawyer. Do not assume that assistance with a tax objection automatically covers that process. Explicitly agree who monitors each procedure and its deadlines. This guide does not provide a general strategy for every tax-related criminal case.

If you also receive an FIOD invitation or a document showing a criminal investigation, read about your position as a suspect in an FIOD investigation. A tax penalty alone does not mean that criminal proceedings are underway.

7. Fictional example: a disputed adjustment with a penalty

Suppose a business owner receives a tax adjustment and a tax offence penalty following an investigation. The owner sent documents to an adviser and believes this defeats every allegation. However, the file does not yet show when those documents were sent or which instructions accompanied them.

Focused preparation brings together the return, requested evidence and original correspondence in chronological order. The lawyer can then distinguish the tax issue from the facts relevant to the penalty allegation. This fictional example does not establish that relying on an adviser is a sufficient defence in an actual case.

8. Checklist for advice about the penalty

Put any approaching deadline at the front of your file and state whether you have already attended an interview or signed anything. Request an initial assessment of the decision, evidence and next steps. Agree the scope and cost without treating any particular reduction as a guaranteed outcome.

• Proposed penalty, assessment and penalty decision, with every attachment and date.
• The return as filed and an overview of the disputed adjustments.
• Investigation report, information requests and your earlier replies.
• Engagement terms and original communications with any adviser involved.
• Any objection already filed, acknowledgements of receipt and other procedural documents.
