WTS Energy provides Employer of Record(EOR) services in Belgium for companies that need to employ professionals without first setting up a Belgian entity. We act as the legal employer, manage compliant employment contracts, payroll, ONSS/RSZ social security, wage withholding, immigration coordination and HR administration, while you manage the employee’s day-to-day work.

Belgium is a practical base for offshore wind, port infrastructure, power, grid, hydrogen, chemicals, industrial maintenance and regional European project teams. It also has a detailed employment framework built around joint committees, collective bargaining agreements, automatic wage indexation, strict working-time rules and regional work-permit administration.

Why choose WTS Energy for EOR in Belgium

WTS Energy is built for companies that need compliant workforce execution in technical and regulated environments.

• Regional European presence. WTS Energy supports EOR services in Belgium through its European office network, including teams in the Netherlands, France, Monaco and the UK.

• Energy-sector specialization. We understand technical hiring for offshore wind, infrastructure, LNG, petrochemicals, ports and industrial projects.

• Belgian payroll control. We coordinate payroll, wage withholding, ONSS/RSZ social security, holiday pay, public holidays and joint-committee obligations.

• Immigration support. We help structure roles and salary packages for non-EU specialists, including highly qualified worker and EU Blue Card routes where available.

• Entity-free hiring. You can employ Belgium-based professionals before opening a Belgian company, branch or payroll registration.

• Hands-on HR support. Employees receive real HR and payroll support, not only access to a self-service platform.

When to use an EOR in Belgium

An Employer of Record in Belgium is useful where speed, compliance and local employment knowledge need to move together.

• Enter Belgium without a local entity. Employ a country lead, project engineer or commercial specialist while testing the market.

• Mobilize an energy project team. Hire technical personnel without building a Belgian HR function first.

• Employ non-EU specialists. Coordinate single-permit planning, salary thresholds and regional work-authorisation filings before the start date.

• Convert a contractor to employment. Reduce risk where a contractor is supervised like an employee, works through client systems or performs core work on a long-term basis.

• Bridge to a Belgian entity. Start employment while incorporation, banking, tax registration and payroll setup are in progress.

• Host temporary project personnel. Use fixed-term employment where the project reason, duration and renewal pattern are defensible.

• Manage compliance recovery. Move direct-pay or informal consultant arrangements into a controlled Belgian employment structure.

Belgium employment and immigration essentials (2026)

Employment contracts and fixed-term employment

Belgian employment contracts should clearly describe the employer, employee, role, workplace, salary, benefits, working time, notice, confidentiality, intellectual property and any mobility requirements. Full-time work is normally linked to the normal weekly duration applicable in the company, commonly 38 hours.

Fixed-term contracts must be written and signed before employment begins. A fixed-term contract normally ends on the agreed end date without notice. Successive fixed-term contracts are restricted: Belgium.be describes the general exception allowing up to four successive fixed-term contracts where each lasts at least three months and the total duration does not exceed two years. With prior approval from the Labour Inspectorate, successive fixed-term contracts of at least six months each may be allowed up to three years.

For EOR, WTS Energy validates whether an indefinite contract, fixed-term contract or project-specific structure is the most defensible option.

Working hours, rest and overtime

Belgian working time is generally limited to eight hours per day and 38 hours per week, or 38 hours on average over a reference period. Effective weekly working time should not exceed 40 hours in principle. Overtime rules, compensatory rest, Sunday work, night work and public-holiday work depend on the legal basis and any joint-committee rules.

The Federal Public Service Employment states that overtime is generally paid at 50% extra for weekday and Saturday hours, and 100% extra for Sunday or public holiday hours. Energy-sector schedules, shutdowns, commissioning, travel and on-call work should be reviewed before employment starts.

Minimum wage and wage setting

Belgium does not use one simple statutory hourly minimum wage. Minimum pay is usually set through collective bargaining agreements at joint committee level, and salaries must not fall below the guaranteed average minimum monthly income where applicable.

Belgium also has a guaranteed average minimum monthly income, known as GGMMI/RMMMG/GAMMI. Brussels Economy and Employment lists the current gross amount as EUR 2,189.81 per month in 2026. Sector wage scales, indexation, seniority, role classification and immigration thresholds can require higher pay.

Paid leave, public holidays and notice

Belgian employees are generally entitled to four weeks of paid annual holiday after a full holiday reference year. Belgium also has 10 statutory public holidays per calendar year.

Notice periods are governed by statutory rules and depend mainly on seniority, start date and whether notice is given by the employer or employee. For post-2014 contracts, Belgium uses detailed statutory notice tables. EOR offboarding should therefore be planned around seniority, contract type, reason for exit and any more favourable collective or contractual rules.

Payroll tax, ONSS/RSZ and employer contributions

Belgian payroll requires withholding of employee social security contributions and professional withholding tax. The National Social Security Office collects ordinary and special contributions, and FPS Finance administers personal income tax.

For 2026 planning, core payroll points include:

• Employee social security contributions in the private sector are generally 13.07% of gross salary, subject to reductions for low wages.

• The standard employer contribution for the private profit sector is 25% of gross salary, with additional contributions, reductions and sector-specific elements possible.

• Personal income tax for income year 2026 is progressive, with federal brackets of 25%, 40%, 45% and 50% before regional and municipal effects.

• Professional withholding tax is deducted through payroll and depends on taxable pay, family status and withholding rules.

• Holiday pay, public holidays, 13th-month pay where applicable, meal vouchers, sector funds and insurance benefits can materially affect the total employment cost.

Because Belgian payroll is strongly influenced by joint committee, salary structure and benefit design, WTS Energy validates the full employer-cost model before onboarding.

Pension obligations

Belgian employees are covered by the statutory social security system, including pension protection funded through ONSS/RSZ contributions. Additional occupational pension arrangements may apply under sector collective agreements, company benefit plans or market practice.

For EOR employment, pension and insurance obligations should be reviewed with the applicable joint committee, role level, salary package and any client site requirements.

Immigration and work authorization

EU, EEA and Swiss nationals can generally work in Belgium under free movement rules, subject to registration steps where relevant. Non-EU nationals normally need the correct work and residence authorisation before starting work.

Belgian work permits are regionally administered. For employment exceeding 90 days, a single permit is usually required and combines work and residence authorization. The applicable authority depends on the work location, such as Brussels-Capital Region, Flanders or Wallonia.

For Brussels-Capital Region applications in 2026, official guidance lists monthly minimum remuneration levels including EUR 3,703.44 for highly qualified staff, EUR 4,748.00 for the European Blue Card and EUR 6,647.20 for executive or management staff. Brussels guidance also states that, from 4 May 2026, work-permit applications for non-European nationals must be submitted through the federal One-Stop counter rather than by PDF or email.

WTS Energy checks the candidate’s nationality, residence status, work location, salary, qualification, role category and start date before confirming a Belgium onboarding timeline.

How WTS Energy’s Belgium EOR works

Before employment

WTS Energy confirms the role, work location, reporting line, salary, benefits, working-time pattern, project duration, joint-committee assumptions and immigration status. We prepare Belgian-compliant employment documentation and align payroll, benefits, leave, social security and onboarding records with the actual assignment.

For non-EU hires, we review whether the role may qualify as highly skilled, EU Blue Card, ICT or another route. We align salary, contract duration, work location and filing timing before a start date is promised.

During employment

WTS Energy administers payroll, payslips, wage withholding, ONSS/RSZ social security, holiday tracking, public-holiday treatment, HR records and employee support. We coordinate changes to salary, role, work location, working-time pattern or project assignment so payroll and documentation stay aligned.

For energy and industrial teams, WTS Energy can support practical workforce requirements such as site onboarding, mobility letters, compliant allowances, rotations, contractor conversion and cross-border coordination.

End of employment

WTS Energy manages notice, final payroll, unused leave, statutory records, benefits closure, equipment return coordination and offboarding documentation. Where an exit is sensitive, we align the process with Belgian notice rules, evidence requirements and any collective agreement obligations.

Compliance and risk management in Belgium

Belgium is a high-compliance employment market where payroll, immigration and worker classification need careful control.

• Permanent establishment risk. Belgium-based employees who habitually negotiate or conclude contracts for a foreign company can create taxable presence concerns.

• Worker misclassification risk. Contractors who work under client authority, follow fixed client schedules and perform long-term core work may be reclassified.

• Joint-committee risk. Wage scales, working time, benefits, notice and funds may depend on the correct joint committee and role classification.

• Payroll contribution risk. ONSS/RSZ, withholding tax, holiday pay, sector funds and benefits must be calculated correctly.

• Fixed-term risk. Successive fixed-term contracts require a legal basis and careful duration control.

• Immigration risk. Non-EU personnel cannot start until the right work and residence status is in place.

• Mobility risk. Cross-border work between Belgium and neighbouring countries can trigger tax, social security, A1 certificate and work-permit questions.

Upcoming legislative changes and watchlist (Belgium, 2026)

Belgium employers should monitor the following 2026 issues:

• Wage norm for 2025-2026. The Federal Public Service Employment states that the maximum wage-cost development margin is fixed at 0% for 2025-2026, while indexations and scale increases remain guaranteed.

• GGMMI/RMMMG updates. The guaranteed average minimum monthly income is listed at EUR 2,189.81 in 2026, and sector wage scales may exceed this level.

• One-Stop counter for work permits. Brussels guidance states that from 4 May 2026, non-European Work-authorisation applications must be submitted through the federal One-Stop counter.

• Regional immigration thresholds. Salary thresholds for highly qualified workers, EU Blue Card, management and ICT categories are region-specific and should be checked before every filing.

• Social-inspection focus. Misclassification, undeclared work, social dumping and cross-border posting remain high-risk areas for international workforce models.

WTS Energy monitors these changes so Belgian EOR payroll, immigration and HR administration remain aligned with current rules.
