When forming a business partnership, you need to register as Partners under a common business name. Fill out the appropriate form for your situation and check the “Partnership” box on the form. If you were previously registered as self-employed with Jobsplus individually, you need to terminate those registrations and re-register under the new partnership name.
If you're setting up a Partnership En Nom Collectif or Partnership En Commandite, first register with the Malta Business Registry (MBR) and get your Partnership Certificate. In this case, partners are considered employees of the partnership and should fill in the “Engagement Form – Employed". Your partnership needs a common VAT Number and a PE number from the Commissioner for Revenue (CfR).
For a civil partnership agreement (Partnership de Facto), that may be registered with the Public Registry, partners are still considered self-employed but under the new common name. Again, you'll need a common VAT Number and, if hiring new employees, a PE number from the Commissioner for Revenue (CfR).
