On 10 September 2026, the Danish IT Supervisory Authority (IT-tilsynet) released its annual assessment of the Tax Administration’s (Skatteforvaltningen) IT landscape. The report highlights significant progress in modernizing core tax systems, with three out of four prior-year recommendations now fully implemented. Key improvements include enhanced cybersecurity posture, improved system stability for taxpayer-facing platforms, and accelerated cloud migration initiatives. The remaining recommendation concerns legacy system decommissioning timelines, where the Authority urges accelerated planning to reduce technical debt and operational risk. This oversight falls under the Danish Public Digitalization Act and GDPR compliance requirements for public sector data processing.
Key Takeaways
- Major Implementation Progress: Three of four critical IT supervisory recommendations from 2025 have been addressed, covering security architecture upgrades, digital service reliability enhancements, and cloud infrastructure adoption across tax administration systems.
- Legacy System Risk Persists: The outstanding recommendation focuses on decommissioning outdated mainframe-dependent applications, with the Authority emphasizing that prolonged reliance increases cyber vulnerability and maintenance costs for taxpayer data processing.
- Compliance and Digitalization Drive: The improvements support Denmark’s digital government strategy and ensure alignment with EU public sector interoperability directives, directly impacting tax filing, collection, and audit system performance for businesses and individuals.
