Definition
A bonus is a special payment made by the employer in addition to the regular salary, which is typically linked to the employee’s continued employment on a specific date – the best-known example being the Christmas bonus. If it is paid for several consecutive years without reservation, a legal entitlement to future payment arises. A discretionary clause can prevent this, but must be formulated clearly and consistently. Cut-off date and repayment clauses are permissible, but only within certain limits – for payments up to one month’s salary, the commitment may not extend beyond 31 March of the following year.

A Christmas bonus may be based on an employment contract, a works agreement, a collective agreement or established company practice. Cut-off date clauses and repayment reservations are only valid under strict conditions.
Distinction from related terms
13th month’s salary: The 13th month’s salary is generally a fixed, agreed-upon additional payment of a remunerative nature. A gratuity, on the other hand, may also be linked to length of service or other conditions.
Bonus / variable remuneration: Bonuses are usually performance-related. Gratuities are often paid regardless of individual performance, for example as a special payment on specific occasions.
Practical tip
Practical tip: If your employer has paid a Christmas bonus without reservation for three consecutive years, you may be entitled to it on the basis of established company practice – even without a contractual provision. Check whether your payslip includes a clause stating that the payment is at the employer’s discretion.
