How to get a NISS as a self-employed worker (recibos verdes)
Freelancers in Portugal work through recibos verdes, the green receipts issued through the Financas portal. Your social security registration follows your tax activity, so the order of steps matters.
Step 1: your NIF comes first
There is no self-employed route without a NIF. Your activity is opened with the tax authority under your tax number, so if you do not hold one yet, obtain it before anything else.
Step 2: open your activity
Register the start of your activity, the inicio de atividade, with Financas, choosing the activity code that matches your work. From that moment you can issue recibos verdes to your clients.
Step 3: apply for the NISS with proof of real activity
Seguranca Social asks for the activity opening confirmation together with issued receipts. An activity with no receipts issued yet is the weakest file; even one or two issued receipts show the activity is real. Add your passport or ID scan and, if you are non-EU, your residence permit, visa or application receipt.
Step 4: contributions and the first year
On a first self-employed registration, contributions become due from the first day of the 12th month after you start activity, unless you opt to begin earlier. You declare income quarterly in Seguranca Social Direta, in January, April, July and October, and pay monthly contributions calculated on the declared income. Keep your SSD login working from day one: that is where every declaration happens.
Foreign clients and the D8 route
If your clients are abroad and you live in Portugal on a D8 visa, your foreign employer or client contracts are accepted as proof of activity for the NISS. The documents still need to be complete and legible, and translations can be requested, so build the file before you file.
Keep every deadline in view
Once your activity is open, your year runs on monthly contributions, quarterly declarations and tax filing dates. Check every deadline in the Portugal Tax Calendar.
