Payroll Services in Belgium

At Mercans, our unwavering commitment to local compliance in Belgium goes beyond a mere checklist. We proactively navigate the intricate regulatory landscape — including Belgium’s sector-specific collective bargaining system and its distinctive double holiday pay mechanics — ensuring your business aligns seamlessly with the country’s norms. Here’s an insight into how Mercans expertly manages key activities, safeguarding both compliance and operational efficiency:

Comprehensive Services Include

Payroll Settlement

• Precise calculations encompassing withholding tax, social security, single and double holiday pay, and other deductions.
• Inclusion of overtime, sector collective agreement entitlements, and applicable allowances.
• Quarterly file preparation for the multifunctional declaration (DmfA) filed with the National Social Security Office (NSSO/RSZ/ONSS).

Payment Processing

• Generation and delivery of payslips.
• Efficient management of single and double holiday pay, including coordination with the holiday fund for blue-collar employees.
• Streamlined SEPA payment processing in Euro.

Regulatory Compliance

• Filing the mandatory Dimona declaration before every new employee starts work, as Belgian law strictly requires.
• Accurate monthly withholding tax remittance and quarterly social security declarations.
• Preparation of the annual individual salary certificate (Form 281.10) for each employee.

Sector Compliance Management

• Identifying the correct Joint Committee (paritair comité) and applicable sector collective bargaining agreement for each role.
• Coordinating with accredited social secretariats where required for statutory filings.
• Expert management of Belgium’s evolving 2026 employment law reforms.

Minimum Wages and Sector Bargaining in Belgium

Belgium does not operate a single, simple national minimum wage in the way many countries do. Instead, a national inter-professional minimum monthly wage (GMMMI / RMMMG) sets a floor — EUR 2,189.81 per month from April 2026 for a full-time worker aged 18 or over — while roughly 100 sector-level Joint Committees (paritair comité / commission paritaire), covering nearly all Belgian employees, negotiate collective bargaining agreements that typically set actual minimum pay well above this national floor. Mercans confirms the applicable Joint Committee and collective agreement for each specific role and sector.

Working Hours

The statutory ceiling is 38 to 40 hours per week depending on sector, but 38 hours has been the near-universal collectively bargained norm since the early 2000s, with some sectors running a 40-hour week offset by compensatory days off. The absolute maximum including overtime is 11 hours per day and 50 hours per week.

Payroll Cycle in Belgium

Salaries in Belgium are typically paid monthly, on the last working day of the month, in Euro via SEPA bank transfer.

Company Registration in Belgium

When establishing a business presence in Belgium to run local payroll, foreign companies typically choose from the following structures, registered through the Crossroads Bank for Enterprises (KBO/BCE):

Setting up and maintaining any of these structures — including the ongoing corporate compliance obligations that come with them — requires dedicated legal and administrative resources. Mercans’ Employer of Record and Global Payroll solutions allow companies to hire and pay employees in Belgium without first establishing any of these entities.

Employer Registration for Payroll in Belgium

Running compliant payroll in Belgium requires several registrations:

• Crossroads Bank for Enterprises (KBO/BCE): Obtain a Belgian enterprise number, generally handled through a notary for a BV/SRL, or directly for a branch.
• National Social Security Office (NSSO / RSZ / ONSS) Employer Registration: Register as an employer before employing any staff in Belgium, via the online WIDE service.
• Dimona Declaration — Before Work Starts: Belgium strictly requires an electronic Dimona declaration to be filed with the NSSO before each new employee’s first working moment — not on the same day, but genuinely before work begins. Non-compliance can carry administrative fines or criminal penalties.
• Accredited Social Secretariat: While not strictly mandatory, affiliation with a government-accredited social secretariat is standard practice, since only these bodies are legally empowered to collect and remit social security contributions on the employer’s behalf.
• Local Bank Account: Needed for SEPA salary payments and social security and tax remittances.

Payroll Taxes in Belgium

Personal Income Tax in Belgium

Belgium applies a progressive federal income tax scale, with brackets indexed annually, plus a municipal surcharge that varies by location, typically ranging from 0% to around 8–9% of the federal tax due.

A basic tax-free personal allowance applies (increasing with dependent children), on top of which the municipal surcharge is layered. Because bracket thresholds are indexed annually and can be quoted for different income or assessment years, Mercans confirms the exact current-year figures for each engagement.

Tax Reporting

Employers must remit withholding tax (bedrijfsvoorheffing / précompte professionnel) to the tax authorities by the 15th of the month following the month in which employees were paid. Social security contributions are declared quarterly through the multifunctional declaration (DmfA), generally due by the last day of the month following the end of each quarter. By the end of February each year, employers must issue each employee’s annual salary certificate (Form 281.10) and file it with the tax authorities.

Social Security in Belgium

Belgian social security contributions are calculated on gross salary, with a flat employee rate and a somewhat higher, category-dependent employer rate.

The employer rate is somewhat higher for blue-collar employees, largely reflecting the additional contribution funding the holiday-pay system for that category, described below. A 2025 reform introduced a cap on the basic portion of employer contributions for quarterly earnings above EUR 85,000 per employee, primarily relevant to senior and executive payroll.

Holiday Pay in Belgium: Blue-Collar vs. White-Collar

Belgium has a distinctive statutory holiday pay system that differs meaningfully depending on worker category, and includes a “double holiday pay” concept on top of ordinary salary continuation during leave.

White-Collar Employees

The employer continues paying normal salary directly during annual leave (single holiday pay), and separately pays double holiday pay directly through payroll — an additional lump sum equal to approximately 92% of one month’s gross salary, typically paid in May or June, pro-rated for employees who did not work a full reference year.

Blue-Collar Employees

Rather than being paid directly by the employer, both single and double holiday pay for blue-collar employees are funded through employer contributions to the National Office for Annual Holidays (RJV/ONVA), which disburses a combined lump-sum “holiday cheque” directly to the employee, generally between 2 May and 30 June each year, regardless of when leave is actually taken.

Termination Payroll in Belgium

Since the 2014 “Unified Status” reform, notice periods for employer-initiated termination of an indefinite contract are calculated using a single statutory formula based on seniority, applying equally to blue-collar and white-collar employees.

For employees hired before 1 January 2014, seniority accrued before that date is calculated under the prior rules and added to seniority accrued afterward under the table above. Recent legislative activity has introduced a maximum cap on employer-initiated notice for contracts starting from mid-2026 onward; Mercans confirms the current cap and its applicability for each engagement, since this is a recently introduced change. Employers may choose to pay an indemnity in lieu of notice — covering base salary and all contractual benefits such as company car, meal vouchers, and group insurance for the full notice period — instead of having the employee work out their notice.

Employee Benefits in Belgium

Mercans, in adherence to Belgian labour law and applicable collective agreements, ensures that employees receive the right benefits by staying vigilant about statutory deductions and entitlements.

• Annual Leave & Holiday Pay: Statutory paid annual leave, combined with the single and double holiday pay mechanics described above.
• End-of-Year Bonus: Where required by the applicable sector collective bargaining agreement, an end-of-year bonus is paid, generally subject to a minimum seniority condition.
• Sick Leave: Continued pay during illness, with duration and funding source depending on worker category and length of incapacity.
• Collective Agreement Benefits: Many additional entitlements — including minimum pay, transport reimbursement, and shift premiums — are set at the sector level through the applicable Joint Committee.
