Employer Register (registration, changes, deregistration)

Under the Single Monthly Employer Report Act, the Employer Register is a newly established register for the monthly reports submitted under that Act. All employers regarded as employers under the Single Monthly Employer Report Act must be recorded in this register, as must all their wage departments, where applicable.

A submission for the entry of an employer in the Employer Register may be made only electronically via e-submission in PDF format. Submissions for details relating to an employer to be changed or corrected, or for deregistration, may be made only electronically via e-submission in XML format. Submissions may be sent via a data box or the CSSA e-Portal.

Obligation to register in the Employer Register:

Once you begin your business activities and become an employer, you must register in the Employer Register no later than two working days before the date on which your first employee is due to start work, but not earlier than 15 days before that date. The same applies to the registration of all wage departments.

Changes to details about an employer or its wage department in the Employer Register

If details recorded about an employer in the Employer Register are changed in any way, you must notify this change within eight days of the date on which you became aware of it. The same applies to changes in the details about your wage department.

Deregistration of an employer or its wage department from the Employer Register

Once you cease to employ your last employee, you must deregister from the Employer Register within eight days of the date on which you ceased to employ that last employee.

If a wage department is closed, the deregistration period is eight calendar days from the date of its closure.

If you registered in the Employer Register on the basis that your first employee was due to start work and that employee does not in fact, take up the work (and no other employee does so either), you must notify this fact within eight days of the date on which that employee was due to start work.
