How do you calculate your notice period in Belgium?

In Belgium, the notice period depends on two things: who ends the contract and your seniority on the day the notice starts. An employer owes from 1 week up to 62 weeks after 20 years, and more beyond. Since 2026, contracts starting from 1 August 2026 have a 1-week notice during the first six months, and contracts starting from 1 June 2026 are capped at 52 weeks.

What decides the length of your notice period?

Your seniority with the employer, counted from the first day of work to the day before the notice starts. The tables are the same for blue-collar and white-collar workers whose contract started from 1 January 2014, as the SPF Employment sets out. The full mechanism is explained in our definition of the notice period.

The second factor is who ends the contract. If your employer dismisses you, the notice keeps growing with seniority. If you resign, it is much shorter and capped at 13 weeks: that case has its own page, how much notice you give when you resign.

‍

How long is the notice when your employer dismisses you?

For a contract that started from 1 January 2014 and before 1 June 2026, the SPF Employment table gives, in weeks:

  • Less than 3 months: 1 week
  • 3, 4 and 5 months: 3, 4 and 5 weeks
  • 6 months to less than 1 year: 6 to 7 weeks
  • 1 to less than 2 years: 8 to 11 weeks, one more week every three months
  • 2 years: 12 weeks. 3 years: 13 weeks. 4 years: 15 weeks
  • From 5 years: 18 weeks, then 3 more weeks per year, up to 60 weeks at 19 years
  • From 20 years: 62 weeks, then 1 more week per year

Example: hired on 1 March 2020 and dismissed with a notice starting on 1 November 2026, you have 6 years of seniority, so 21 weeks of notice.

‍

What changed in 2026?

Two laws changed the table for new contracts only. First, for contracts whose work started from 1 June 2026, the employer’s notice is capped at 52 weeks, reached at 17 years of seniority. The cap also applies to a notice indemnity, as Securex explains.

Second, for contracts whose work started from 1 August 2026, the notice is 1 week during the whole first six months, whether the employer or the employee ends the contract. It was 1 to 5 weeks before, according to Securex. From six months on, the usual table applies. This is not a return of the probation period, but it works much like one.

‍

When does the notice start, and what if you were hired before 2014?

A notice starts on the Monday after the week in which it was given. A registered letter counts as received on the third working day after it is sent, so a letter posted on a Thursday starts the clock on the Monday eleven days later. During a notice given by your employer, holidays, sickness and some other absences suspend it, as the SPF Employment lists.

If your contract started before 1 January 2014, the notice has two parts: one for your seniority up to 31 December 2013, under the old rules, and one for your seniority since 2014, under the current table, as the SPF Employment details. If your employer prefers to end the contract at once, it pays a notice indemnity instead.

What is outplacement, and who is entitled to it?

Outplacement is job-search support paid by your employer when it dismisses you. In Belgium it is mandatory in two cases: if your notice period or indemnity is at least 30 weeks, whatever your age, or if you are 45 or older with at least one year of seniority and a shorter notice. It is not owed after a resignation or a dismissal for serious misconduct. It usually means 60 hours of coaching.

What is a notice indemnity, and when is it paid instead of notice?

A notice indemnity is the payment owed by the party that ends an employment contract immediately instead of giving the notice period. It equals your current pay and contractual benefits for the length of the notice, or for the part not worked. The employer usually pays it, but an employee who leaves without notice owes it too. It is paid in one go and the contract ends at once.

How much notice do you give when you resign?

When you resign in Belgium, your notice depends only on your seniority with the employer and is capped at 13 weeks, reached after 8 years. It runs from 1 week in the first months to 6 weeks between 2 and 4 years. For contracts starting from 1 August 2026, the notice is 1 week during the first six months. Your employer can agree to let you leave earlier.
