SIOD recovers more than €100 million in first-quarter social-fraud drive
Belgium's first-quarter social-fraud drive recovered more than €100 million, according to the Q1 figures cited from the Social Information and Investigation Service's 2026 reporting cycle. The result gives the De Wever government's new social-fraud strategy an early measurable outcome after the SIOD action plan took effect on 1 January 2026. SIOD says its 2026-2027 plan targets 12,000 joint checks in 2026 and 13,000 in 2027, with priority for higher-risk sectors including construction, cleaning, transport and digital platforms. The number should be read carefully: SIOD says arrondissement-cell statistics cover only joint controls and are only a fraction of the more than 100,000 annual investigations carried out by federal social inspectorates. The political issue is therefore not just recovery, but whether Belgium can sharpen enforcement without turning routine labour-market compliance into a burden for compliant employers.
This matters first for Belgian workers, compliant employers, SMEs and taxpayers. SIOD's action plan says the enforcement focus is social dumping, undeclared work and organised fraud, areas that can undercut wages, social-security financing and fair competition. For workers in higher-risk sectors such as construction, cleaning, transport and platform work, stronger inspections may improve protection. For businesses, the key test is whether risk-based targeting catches abusive operators without adding indiscriminate administrative pressure to firms already following the rules.
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.
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.
Opposing perspectives
- Federal social-fraud enforcement authorities
SIOD's action plan argues that risk-based inspections are needed to protect social-security financing, workers and fair competition. The strongest version of this view is that enforcement should concentrate scarce inspection capacity on organised fraud, social dumping and high-risk sectors, rather than dispersing controls randomly across the economy.
- Compliant employers and SMEs
SIOD's own action-plan language says the focus is not the bona fide entrepreneur. The strongest business-side reading is that enforcement is legitimate only if data-led targeting separates deliberate abuse from administrative mistakes, because excessive blanket controls would add costs for firms already paying wages and contributions correctly.
- Academic researchers in SIOD's scientific network
The SIOD academic-chair material frames social fraud and social dumping as complex labour-market phenomena requiring research, multidisciplinary cooperation and practical policy recommendations. The strongest research view is that recovery totals alone are not enough: Belgium also needs evidence on deterrence, inspection methods, worker protection and unintended compliance burdens.
