What it is about

On 11 November 2026 the Dutch DPA published the first State of data protection at the Tax Administration. It takes stock of the intensified supervision that started in 2024. On 12 topics the DPA assesses whether the Tax Administration complies with the law and how fast it improves. On 2 topics compliance is in order: reporting data breaches and carrying out DPIAs. On the other 10 compliance falls short. Selection algorithms are not sufficiently substantiated to prevent discrimination, the Tax Administration cannot show meaningful human intervention in algorithmic decisions where the law requires it, security and the review of logging are not in order, data are not deleted on time, access requests are not always handled on time and correctly, and the record of processing activities is incomplete. According to plan the citizen service number (BSN) will be removed from the payment reference for citizens by the end of 2026, and the applications Informatiesjabloon and KTA are to be switched off in 2027 and 2028. The intensified supervision runs until mid 2029 for now; the next edition follows in January 2028.

What this means in practice

The report shows what the DPA looks at in a large organisation, and those points apply to everyone. A DPIA alone is not enough: anyone selecting with algorithms must substantiate the selection criteria to prevent discrimination and be able to show that a person genuinely reviews the outcome where Article 22 requires it. Control who has access to personal data and review the logging. Do not use the citizen service number where it is not needed, such as in a payment reference. Measures must also keep working; that requires a privacy organisation that holds on to improvements (Article 24). The report is not a fine in itself, but the Tax Administration must follow the DPA's instructions, and otherwise the DPA can take enforcement action.
