If you are a contractor with a Portuguese entity, you can use a special regime called Recibos Verdes, that means the social security payments are smaller and independent of your salary, I think 100€ per month is the minimum. This was a loophole by many companies used to avoid having "real" employees, and there have been crackdowns on this, it's mostly for temporary contractors. If you have 3 years of concurrent "temporary" contracts with the same entity, you must ve registered as an employee.
