What severance pay is required in Belgium?

Severance pay in Belgium is a mandatory entitlement calculated primarily on the basis of an employee';s seniority and remuneration. Since the landmark reform introduced by the Act of 26 December 2013 - commonly called the "single statute" or statut unique - Belgium unified the rules for blue-collar and white-collar workers into one coherent framework. Employers who dismiss an employee without cause, or who give notice that is shorter than the legal minimum, must pay a notice indemnity equal to the remuneration the employee would have earned during the applicable notice period. This guide covers how the notice period is calculated, what counts as remuneration, the key exceptions, and the practical costs employers face.

Belgian employment law does not use the term "severance pay" in the same way as many other jurisdictions. The correct legal concept is the vergoeding wegens willekeurig ontslag (arbitrary dismissal indemnity) for certain categories, but the dominant mechanism is the notice indemnity (opzeggingsvergoeding). When an employer terminates a contract of indefinite duration without giving the employee the full statutory notice period to work out, the employer must pay a lump sum equal to the gross remuneration - including all benefits - that the employee would have received during that notice period.

The notice period itself is determined by the employee';s seniority, measured in complete quarters of service. The Act of 26 December 2013, as codified in the Employment Contracts Act (Wet op de arbeidsovereenkomsten), sets out a progressive scale. For the first quarter of employment the notice period is two weeks. It rises incrementally, reaching thirteen weeks after three years of seniority, and continues to grow - reaching a maximum of sixty-two weeks for employees with very long tenures. For seniority built up before the single statute came into force, a transitional regime applies, meaning that some long-serving employees carry a "frozen" entitlement from the old rules that is added to the new-regime entitlement.

In practice, founders and HR managers of international companies are often surprised by how quickly notice periods accumulate. An employee with eight years of seniority may already be entitled to a notice period of twenty-six weeks or more, which translates directly into a cash obligation if the employer opts for immediate termination.

The notice indemnity is not calculated on basic salary alone. Belgian law - specifically Article 39 of the Employment Contracts Act - requires that the indemnity reflect the employee';s current gross remuneration plus all advantages acquired by virtue of the contract. This is a broad definition and regularly catches foreign employers off guard.

Elements that must be included in the calculation base:

• Monthly gross salary, including any guaranteed bonuses or fixed supplements.
• The value of a company car for private use, typically assessed using a standard formula or the actual benefit-in-kind value.
• Meal vouchers, eco-vouchers and group insurance contributions paid by the employer.
• Variable pay such as commissions or performance bonuses, averaged over the twelve months preceding dismissal.
• Holiday pay entitlements that are structurally part of the remuneration package.

A common mistake is to calculate the indemnity on basic salary only and ignore the car benefit or the annualised value of a target bonus. The National Social Security Office (Rijksdienst voor Sociale Zekerheid - RSZ) and labour courts consistently include these elements, and underpayment exposes the employer to claims with interest.

The gross indemnity is subject to social security contributions and withholding tax in the same way as regular salary, so the net amount received by the employee is lower than the gross figure. Employers should budget on a gross basis.

The single statute of December 2013 did not erase entitlements built up under the old system. For employees hired before the reform took effect, seniority is split into two parts: the period before the cut-off date and the period after. Each part is calculated under its own rules, and the two results are added together.

Under the old white-collar rules, notice periods were calculated using a formula linked to annual remuneration thresholds. Under the old blue-collar rules, shorter periods applied, which is why the reform was introduced - to eliminate the inequality. The transitional regime means that a long-serving white-collar employee dismissed today may have a combined notice entitlement that is substantially higher than the new-regime scale alone would suggest.

For employers acquiring a Belgian business or inheriting staff through a transfer of undertaking (overgang van onderneming under the Act of 5 March 2002 implementing the EU Acquired Rights Directive), the transferred employees carry their full seniority - including the pre-reform portion - to the new employer. Many underestimate this liability when valuing an acquisition target.

Not every termination triggers a notice indemnity. The rules differ significantly depending on who initiates the end of the contract and on what grounds.

Dismissal for serious cause (dringende reden) is the main exception. If an employer can demonstrate that the employee committed a serious fault making any further professional collaboration immediately and definitively impossible, the employer may terminate without notice and without indemnity. The bar is high: the employer must notify the employee within three working days of becoming aware of the facts, and must give a precise description of the serious cause within three further working days. Courts interpret these deadlines strictly, and a procedural error - even a minor one - can invalidate the dismissal for serious cause and expose the employer to the full notice indemnity.

Resignation by the employee also requires a notice period, but the employee';s notice obligations are shorter than the employer';s. If an employee resigns without giving proper notice, the employer may claim an indemnity from the employee, though in practice this is rarely pursued.

Mutual termination by agreement (minnelijke beëindiging) is a common and flexible route. The parties negotiate a termination package - often including a payment equivalent to some or all of the notice period, outplacement support, and a waiver of claims. This route avoids litigation risk but requires genuine consent; courts will scrutinise agreements signed under pressure.

Collective redundancy triggers additional obligations under the Act of 13 February 1998 (Wet Renault), including mandatory information and consultation with employee representatives before any decision is taken, and specific notification to the regional employment authority. Failure to follow the Renault procedure can result in the dismissals being declared null and void.

Beyond the notice indemnity, Belgian law imposes outplacement obligations on employers in certain dismissal scenarios. Outplacement is a package of career guidance services funded by the employer to help the dismissed employee find new work.

The obligation applies when:

• The employee is at least forty-five years old at the time of dismissal, or
• The notice period or indemnity corresponds to at least thirty weeks of remuneration.

In the second scenario, the employer must offer outplacement worth at least four weeks of remuneration. If the employer fails to make the offer, the employee can claim a supplementary indemnity. The cost of outplacement is typically borne by the employer and is in addition to the notice indemnity, not a substitute for part of it.

A non-obvious requirement is the activering mechanism: when a notice indemnity exceeds a certain threshold, part of the gross indemnity is redirected to a fund managed by the National Employment Office (Rijksdienst voor Arbeidsvoorziening - RVA) to finance the employee';s reintegration. This reduces the net amount paid directly to the employee and is sometimes misunderstood as a tax, but it is a social security contribution with a specific purpose.

Scenario one - a mid-level manager with six years of seniority: An employer terminates a sales manager earning a gross monthly salary of EUR 5,000, with a company car valued at EUR 500 per month and an average annual bonus of EUR 6,000. The total monthly remuneration base is approximately EUR 6,000 (salary plus car plus one-twelfth of the bonus). With six years of seniority under the new regime, the notice period is approximately twenty-one weeks. The gross notice indemnity is therefore roughly EUR 6,000 multiplied by approximately 4.8 months, producing a significant six-figure obligation before social security contributions. This illustrates why Belgian dismissal costs are among the highest in Western Europe.

Scenario two - a short-tenure employee with two years of seniority: A junior employee earning EUR 2,800 gross per month with no variable pay and no company car is dismissed after two years. The notice period under the new regime is approximately nine weeks. The gross indemnity is approximately EUR 2,800 multiplied by 2.1 months - a more manageable sum, but still a meaningful cost for a small business.

Professional fees for handling a contested dismissal - including legal advice, drafting of termination documents, and representation before the labour tribunal (arbeidsrechtbank) - typically start from the low thousands of EUR and can rise substantially if the matter proceeds to full litigation. Settling early is almost always more cost-effective.

What happens if an employer gives a shorter notice period than the law requires?

If the notice period given is shorter than the statutory minimum, the employer must pay a notice indemnity covering the shortfall. The indemnity is calculated on the full remuneration package - not just basic salary - for the number of weeks by which the actual notice fell short of the legal requirement. The employee does not need to prove any additional harm; the entitlement arises automatically from the breach of the statutory notice obligation. Labour courts in Belgium apply these rules strictly, and employers who attempt to negotiate a reduced payment without the employee';s genuine and informed consent risk a claim for the full balance plus interest. The statute of limitations for such claims is generally one year from the date of dismissal.

How long does it take to resolve a severance dispute in Belgium, and what does it cost?

A negotiated settlement can be reached within a few weeks if both parties are willing. If the matter proceeds to the labour tribunal, first-instance proceedings typically take between six months and two years depending on the court';s workload and the complexity of the case. Appeals to the labour court of appeal (arbeidshof) add further time. Legal costs vary widely: straightforward cases handled efficiently may cost a few thousand EUR in professional fees, while contested multi-issue disputes involving variable pay calculations or serious-cause arguments can cost considerably more. Employers should factor in the cost of management time and reputational risk when deciding whether to contest a claim.

Can the parties agree to a lower severance payment than the statutory minimum?

In principle, no. The notice indemnity is a minimum standard set by law and cannot be waived in advance or reduced by individual agreement. However, once the employment relationship has ended, the parties may reach a settlement that includes a payment lower than the theoretical maximum, provided the employee signs the agreement freely and with full knowledge of their rights. Belgian courts look carefully at whether the employee had independent legal advice and whether the agreement was signed under time pressure. Collective bargaining agreements (collectieve arbeidsovereenkomsten - CAO) at the sector or company level can supplement the statutory minimum but cannot reduce it below the floor set by the Employment Contracts Act.

Severance pay in Belgium is a structured, seniority-driven obligation that can represent a substantial financial liability for employers. The single statute unified the rules for all employees, but the transitional regime for pre-reform seniority adds complexity. Remuneration is defined broadly, outplacement obligations apply in many dismissals, and procedural errors in serious-cause dismissals can be costly.
