Self-employed workers have until April 30 to submit the quarterly declaration to Social Security, relating to income obtained in January, February and March. Delivery is mandatory and must be made exclusively online, through the Direct Pension portal.
The warning gains particular relevance at a time when the IRS campaign is also taking place, which could lead some taxpayers to forget this contribution obligation. At issue is an essential procedure for calculating contributions for the coming months.
According to data from the National Statistics Institute for 2025, cited by , there were around 773 thousand self-employed workers in Portugal. A significant portion of these professionals are covered by this quarterly reporting obligation.
Delivery is made on the Social Security portal
Submission of the declaration does not require in-person travel. The process takes place through the Direct Pension portal, in the area designated for self-employed workers.
The route indicated for delivery goes through Work, then Remuneration and contributions, followed by Independent Workers and, finally, Submit a quarterly statement. It is in this space that the income for the quarter in question must be reported.
After submission, the worker receives a notification in the platform’s Message Box indicating the fixed contribution base and the estimated value of contributions payable in the following quarter.
Amount payable can be adjusted
Despite this initial prediction, Social Security calculates the exact amount to be paid every month. This means that there may be adjustments depending on the taxpayer’s specific situation.
Among the examples cited are situations of being unable to work due to illness, which can lead to revisions to the initially predicted value. Whenever a new contribution obligation arises, the worker is informed through the portal itself.
This monitoring is considered essential to avoid failures in compliance and to ensure that the amounts calculated reflect the contribution reality of each independent professional.
How to check outstanding amounts
The contribution status can also be consulted online, through the Payments and debts area, in the Current Position option, followed by Amounts to be paid.
In this space, the portal has two distinct tabs. One of them concerns Current Contributions, where the amounts appear within the payment deadline in the current month.
The other tab refers to Delayed Contributions, bringing together amounts from previous months already due, as well as the respective late payment interest, when applicable.
Failure to comply may have consequences
Using these tools, self-employed individuals can select the amounts they wish to pay and issue payment documents independently, without the need for in-person assistance.
Social Security warns that failure to comply with this obligation may have consequences for the calculation of contributions. Therefore, anyone who has not yet submitted their quarterly declaration should do so in advance, avoiding setbacks in the last few days of the deadline.
