Belastingdienst Tech Stack

Dutch tax authority processing millions of filings and compliance operations nationwide

Government Administration Den Haag 10,001+ employees Government Agency

Belastingdienst operates a sprawling government IT estate—30,000+ staff across tax, customs, benefits, and fraud investigation units—processing millions of filings and hundreds of millions in benefit payouts annually. The tech stack reveals a hybrid modernization path: legacy systems (SAP, SAS, Jenkins, Power Designer) coexist with cloud-native infrastructure (Kubernetes, OpenShift, ArgoCD, Tekton), and hiring priorities skew heavily toward finance and engineering roles, suggesting active backend system overhauls and compliance automation work.
