The certidão de não dívida da Segurança Social is a document that proves someone has no outstanding debts with the Portuguese social security. This certificate is required for the tax-free import of a vehicle into Portugal and is requested by customs as part of the process.
If the applicant (for example, during emigration) is not yet registered in the Portuguese social security system, they will receive a document stating that no registration exists. This document then serves as proof that there is no debt with social security.

Getting the social security document can be a bit challenging. Not all employees know what this is and they may not understand why it is needed.
Here is a detailed instruction for the employee at Social Security. If you run into trouble, show the employee the Portuguese text below and show the example:
Certidão de Não Dívida à Segurança Social
A certidão de não dívida à Segurança Social é um documento que comprova que uma pessoa não tem dívidas pendentes perante a Segurança Social portuguesa. Este certificado é obrigatório para a importação de um veículo com isenção de impostos para Portugal e é exigido pela autoridade aduaneira como parte do processo.
Se o requerente (por exemplo, no caso de emigração) ainda não estiver registado no sistema da Segurança Social portuguesa, será emitido um documento a indicar que não existe registo. Este documento serve como prova de que não existem dívidas à Segurança Social.
Se não souber como obter este documento, por favor pergunte a um colega ou ao responsável.
