Self-Employed Workers
Quarterly Declaration
Self-employed workers must submit their quarterly declaration. To do this, simply go to SSD, to the Emprego > Trabalhadores Independentes menu and select the " Regime declaração trimestral " option followed by " Registar declaração trimestral ". After indicating the income earned in the three months prior to the declaration, click on " Entregar declaração ".
The amount to be paid in the following three months will be available in the personal area. You can also choose to pay by ATM reference or by direct debit.
