On this page, you must indicate if you have income to report for the last quarter. The information must be completed for each of the last 3 months.

If you have income to report, select "Yes" and "Next step"

If you did not have any income during the last quarter, click on "No". If you do not have a quarterly income to report, your statement ends here.


5. Information on the income obtained


If you have received income as a self-employed person in the last 3 months, you must then enter the values of the self-employed according to their origin (service provision, sale, local accommodation, etc.) for each of the last 3 months.

 As you complete the figures, they are automatically added together, giving the "Total of the quarter", ie the total income taken into account for the calculation of the contribution to the Portuguese social security.


When you are done filling out this page, go to "Next Step".


6. Allowances, capital gains and / or intellectual or industrial property


Income related to allowances (unemployment or other), capital gains and / or intellectual or industrial property are not taken into account for the determination of the income concerned. If you want them to be taken into account when calculating social security contributions, you can indicate this in the following table.

If you choose to take these returns into account when calculating your auto entrepreneur contributions, you will need to report them in the table below.


7. Estimated monthly amount of social security contribution


Finally, in the last step, you are immediately informed of the amount of the monthly contribution planned for the next 3 months. As a freelance worker in Portugal you will have to pay the same amount for the 3 months following this declaration.


You can also choose the variation of your contribution, a value of 25% higher or lower than the expected amount, according to your needs. Be careful not to abuse this maneuver because the Portuguese tax authorities control income earned as a self-employed person.
