SIOD recovers more than €100 million in first-quarter social-fraud drive
Belgium's early 2026 social-fraud figures give the federal government's new risk-based enforcement plan its first budgetary test.
In 30 seconds
- The SIOD Q1 update cited in the lead puts first-quarter 2026 recovery at more than €100 million.
- SIOD says its 2026-2027 action plan took effect on 1 January 2026.
- SIOD says the 2026 target is 12,000 joint controls, rising to 13,000 in 2027.
- SIOD says 2025 social-fraud enforcement yielded €414.6 million.
SIOD/SIRS (Belgium's Social Information and Investigation Service, the federal body coordinating social-fraud enforcement) links inspectorates, labour prosecutors and policy bodies. Rob Beenders (Vooruit federal minister for consumer protection, social fraud, persons with disabilities and equal opportunities since 3 February 2025) carries the social-fraud portfolio in the De Wever government. The De Wever government (Belgium's federal coalition sworn in on 3 February 2025 under Prime Minister Bart De Wever) made social-fraud enforcement part of its budget and labour-market agenda. RSZ/ONSS (National Social Security Office) collects employer social-security contributions. RVA/ONEM (National Employment Office) administers unemployment rules and controls. RIZIV/INAMI (National Institute for Health and Disability Insurance) supervises sickness and healthcare-related social insurance. RSVZ/INASTI (National Institute for the Social Security of the Self-employed) covers self-employed social security. UGent (Ghent University) hosts SIOD's academic chair on reducing social fraud and social dumping.
Background
Belgium has gradually moved social-fraud policy from episodic controls toward coordinated, data-led enforcement. SIOD's archive shows annual action plans dating back to 2017 and a 2022-2025 strategic plan before the current 2026-2029 cycle. SIOD says the 2025 annual report recorded 147,863 closed investigations, 15,337 joint arrondissement-cell controls and €414.6 million in social-fraud yield. A law of 15 May 2024 created a scientific committee inside SIOD, and SIOD says its academic chair with UGent was launched on 9 November 2023 to connect inspections with research.
Why now
The story is timely because Q1 2026 is the first reporting period after SIOD says the 2026-2027 social-fraud action plan entered into force on 1 January 2026. The first-quarter recovery figure is an early test of whether the De Wever government's risk-based strategy is producing visible results.
What to watch
Watch SIOD's next quarterly statistics, the pace toward the 12,000 joint-control target for 2026, and any parliamentary scrutiny of how recovered sums are calculated. The 2026 annual report will be the first fuller benchmark for comparing the new strategy with the €414.6 million yield SIOD reported for 2025.
What to do
Workers who suspect undeclared work, exploitation or labour-related discrimination can use Belgium's social-fraud reporting channel, which SIOD says accepts reports from citizens, businesses and organisations. Employers in priority sectors should expect more targeted checks and should keep payroll, posting, subcontracting and social-security documentation in order. The story does not change benefit rules by itself; it signals stronger enforcement of existing obligations.
Impact
Regional — The effect is federal in design but uneven in practice. SIOD coordinates federal inspectorates including RSZ/ONSS, RVA/ONEM, RIZIV/INAMI and RSVZ/INASTI, while arrondissement cells operate through local judicial districts across Flanders, Wallonia and Brussels. SIOD says its joint-control statistics cover those arrondissement-cell operations, not every autonomous inspection by each federal service. Brussels, Antwerp, Liège, Ghent and other labour-market hubs may therefore see different enforcement intensity depending on sectoral risk, cross-border work patterns and the presence of transport, construction, cleaning or platform operators.
