What documents do I need to submit to get a NISS if I’m self-employed?

As a self-employed individual, the Social Security office needs to verify your self-employment activity to issue a NISS. Please ensure you provide the following documents:

1. Document Attesting to Self-Employment Activity:
   • Comprovativo da Declaração de Início de Atividade (Proof of Declaration of Start of Activity) from the Portal das Finanças

2. Copy of Receipts and Invoices:
   • Proof of issued receipts and invoices to your clients

*Note: The requirements for obtaining a NISS are subject to change by the Social Security office. While we do our best to keep this guide updated, we recommend checking directly with them for the most accurate information.
