STARTING A BUSINESS
Both Portuguese nationals and foreigners may set up a business through the intermediary of a lawyer, solicitor or notary in the possession of a digital certificate.
There are no restrictions on foreigners setting up a company in Portugal, as long as they are legal residents and have the necessary work permits and minimum capital investment to do so.
They must have:
A Residency Card (Cartão de Residência) issued by the Portuguese Immigration Service or SEF (Serviços de Estrangeiros e Fronteiras)
A Tax Number (Numero Fiscal de Contribuinte), whether the process of starting up the business has begun or not, those intending to work need to be registered for tax purposes
A Social Security Number (Cartão de Segurança Social): register at the Social Security Office (Repartição de Segurança Social). All foreign nationals intending to stay in Portugal over 180 days and work have to pay social security
