A concise overview of every 2026 update to Belgium’s Check-in at Work regime, new thresholds, expanded sectors, enforcement priorities, and the runway to the 2027 working-time mandate.
2026 is the year Belgian Check-in at Work stops being “construction’s problem” and becomes a wider compliance discipline. Updated thresholds, the cleaning sector’s full year under CIAO, fresh enforcement campaigns and a hard 2027 deadline for daily working-time records mean every employer with subcontractors, posted workers or sector-specific obligations needs to refresh their playbook. This summary maps every 2026 change against the current Check-in at Work obligation, so directors and compliance officers know what to do this quarter, what to budget for next, and what to expect when an inspector turns up. We’ll cover threshold updates, sector additions, enforcement signals, and how to align CIAW with the working-time obligations coming into force on 1 January 2027.

Why CIAW Legislation Is Moving in 2026
Belgian Check-in at Work was originally a 2014 construction-sector tool to fight social fraud. It has grown steadily since: cleaning was added in 2019, then expanded to full CIAO (entry and exit times) in 2025; meat-processing followed; and 2026 is the bridging year before new rules takes effect on 1 January 2027. Three pressures are reshaping the rules:
- Brussels and Antwerp inspection campaigns produced higher-than-expected fine volumes in 2024 and 2025.
- The Confederation of Construction and sector federations pushed for clearer thresholds and digital-first defaults.
- The labour ministry needed CIAW data to feed into the 2027 working-time architecture without re-inventing it.
The net effect: thresholds tighten, sectors widen, and the inspection process gets more data-driven. Our CIAW FAQ is updated quarterly to track the moving pieces.
What this means for directors right now
Companies that ran CIAW as an afterthought in 2024 are being audited harder in 2026. The companies sailing through inspections are running CIAW as part of a unified Time Registration and attendance platform.
Updated Thresholds and Sector Scope
The 2026 thresholds in force at the time of writing:
Construction
- ≥ €500,000 site value (excl. VAT) with no subcontractor → CIAW required.
- Any site with two or more subcontractors → CIAW always required.
- Any site with one subcontractor and works > €5,000 → CIAW required.
- Threshold reviewed every two years; next review expected late 2026.
Cleaning
- Contracts > €30,000 (excl. VAT) → CIAW + CIAO (entry and exit times).
- The cleaning sector is now in its second full year under Check-in and Out at Work, and the labour ministry has flagged this threshold for possible reduction in the 2026/2027 review window.
Meat processing
- Activities > €5,000 → CIAW required for slaughterhouses, cutting plants and processing facilities under PCs 118.03 and 118.07.
- 2026 inspection focus: traceability of posted workers and chain-liability across cutting subcontractors.
Other 2026 changes
- Confirmed exemptions for solo deliveries, advisory visits and short consultative inspections.
- Strengthened documentation requirements for self-employed workers operating on covered sites.
- Higher fines indexation (the underlying €300 administrative fine is now indexed annually).
- Greater integration between CIAW and the Limosa posted-worker declaration.
| ⚠️ Watch-out: Several CBAs (collective bargaining agreements) sit on top of the legal threshold and can lower it further for specific subsectors. Always cross-check the CBA when a contract sits close to a threshold. |
Enforcement Priorities NSSO Has Flagged for 2026
The 2026 NSSO enforcement plan emphasises four themes:
- Chain-liability, main contractors must demonstrate they actively verified each subcontractor’s CIAW posture. A blanket “they handle their own” defence is no longer accepted.
- Posted workers, cross-referencing Limosa A1s with CIAW registrations across multiple sites.
- Cleaning CIAO accuracy, entry/exit pairs must match within reasonable tolerance; gaps trigger automatic review.
- Digital-first evidence, paper registers are formally still acceptable but treated as low-quality evidence. Expect inspectors to spend longer at sites that can’t produce a digital export.
Field reports from the federal employment service confirm a higher visit rate in 2026, especially during peak construction and cleaning seasons.
Quick Reference, What Changed, What Didn’t
| Topic | 2025 status | 2026 status | Action for employers |
| ✅ Construction threshold | €500K / €5K / 2+ subcontractors | Unchanged | Re-verify per site |
| ✅ Cleaning threshold | €30K + CIAO required | Unchanged, under review | Audit exit-time accuracy |
| ✅ Meat-sector threshold | €5K | Unchanged | Focus on subcontractor chain |
| ⚠️ Chain-liability evidence | Documentation encouraged | Documentation expected | Require digital proof from subcontractors |
| ⚠️ Posted-worker integration | Limosa + CIAW separately | Cross-checked automatically | Pair every Limosa with a CIAW entry |
| ⚠️ Administrative fines | €300 base | Indexed upward | Budget for higher exposure |
| ❌ Paper-only attendance | Tolerated | Tolerated but flagged | Move to digital before 2027 |
| ❌ Manual exit-time logs | Acceptable | Discouraged | Automate via CIAO |
Items marked ❌ remain legal but signal to inspectors that the rest of your file may be weak.
Implementation Steps for 2026, A Practical Checklist
A 90-day plan to bring 2026 readiness home:
- Audit every active site against the updated thresholds, construction, cleaning, meat.
- Re-tender subcontractor agreements with explicit CIAW clauses and digital-proof requirements.
- Move any remaining paper attendance to a digital Check-in at Work platform.
- For cleaning contracts, configure full entry/exit pairs via Check-in and Out at Work.
- Pair every CIAW worker with their Limosa A1 (where applicable) inside a single record.
- Train site managers on the inspection process, what an NSSO inspector will ask for.
- Schedule a quarterly self-audit against the construction industry overview and the construction pillar.
- Budget the fine indexation into your 2026 compliance cost model.
The 2027 Runway: Aligning CIAW with the Working-Time Mandate
2026 is the year to align CIAW with the 2027 working-time obligation. The EU’s CCOO ruling, already binding via case law, becomes hard Belgian law from 1 January 2027, requiring every employer to keep an objective, reliable daily working-hours record.
- One system, two obligations: Most companies will use a single Time Registration platform that produces CIAW entries on covered sites and a daily working-time record for every other employee.
- Payroll integration: Belgian payroll providers (SD Worx, Partena, Acerta) have all confirmed 2027 readiness on the data-ingestion side; the bottleneck is on the employer side.
- GDPR posture: The Belgian Data Protection Authority has published guidance on storing working-time data, minimum retention, access controls, and worker rights.
- Tendering: Expect more public tenders to require a 2027-ready attendance solution.
- Sector federations: Agoria and other federations are publishing sector-specific 2027 readiness templates throughout 2026.

Frequently Asked Questions
Did the €500,000 construction threshold change in 2026?
No, the construction threshold is unchanged at the time of writing, but it is scheduled for review later in 2026. The other triggers (one subcontractor > €5,000; two or more subcontractors) are also unchanged. A configurable Check-in at Work platform applies the right rule per site without manual re-work.
Is the cleaning sector still under CIAO in 2026?
Yes. Cleaning contracts above €30,000 require both entry and exit times to be registered. 2026 is the second full year of Check-in and Out at Work in the cleaning sector, and the threshold is under review for a possible reduction.
How does the 2026 enforcement campaign affect main contractors?
Main contractors face stricter chain-liability checks: NSSO inspectors expect documented evidence that you verified each subcontractor’s CIAW posture before they entered the site. Our CIAW FAQ lists the new evidence requirements.
Will the 2026 updates create extra GDPR obligations?
Yes, anytime working-time and attendance data expand, GDPR retention and access controls must be reviewed. The Belgian DPA has published guidance, and most digital Time Registration platforms now include GDPR controls out of the box.
What’s the most important thing to do before 1 January 2027?
Move every paper-based attendance process to a digital platform that can produce both CIAW entries and a daily working-time record. The construction pillar walks through the 12-month migration plan.
