As an employer, you report a termination of employment via MijnBFNL. Search for the employee's active subscription and provide the termination date — you will immediately see the earliest possible end date.
Is the subscription still within the initial fixed term (6 or 12 months)? Then the subscription continues until the end of the term and no credit invoice will be issued.
Can the subscription be terminated early? Then you will receive a credit invoice.
Remaining subscription costs that have not been credited may be settled with the employee's final salary.
