If you are a freelancer or a self-employed professional rendering services to one or two employers by issuing service fee invoices (i.e. with contracts concluded in accordance with article 39 (9) of Law 4387/2016) or you are employed by one employer as a salaried person and you also provide services to up to two employers, you need to indicate that you are subject to this provision, on the service fee invoice you issue to your employer.

This ensures both the timely payment of contributions and the notification of those liable to pay.
