O By means of a shared publication on social networks, the government has recalled that self-employed workers have until the end of the month to deliver the quarterly declaration, as Social Security had also recalled.
“Are you an independent worker? You have until October 31 to deliver your Quarterly Declaration. The declaration shall include income received in July, August and September 2026, which shall serve as a basis for the calculation of contributions from the next three months“, the government said.
The Executive also explained how to deliver: “Go to the Social Security Portal and follow the path: Work → Remunerations and contributions → Independent Workers → Deliver quarterly statement”.
Social security had also warned
At the beginning of the month, the Social Security Institute issued a similar warning: “Independent Workers must deliver their Quarterly Declaration by 31 October,” said the ISS, adding: “This procedure, conducted exclusively through the Social Security Portal, is essential for the establishment of the contribution base for the following period.”.
In this statement, “it should indicate the income received in July, August and September 2026”, and “these values will serve as a basis for calculating the contributions due in October, November and December”.
Delivery of the quarterly statement must be made on the Social Security portal through the Work menu > Compensation and Contributions > Independent Workers > Deliver quarterly statement.
“ After submission, the worker will receive a notification in his Message Box with the indication of the fixed incidence base and the expected amount of the planned contribution”, explains the Social Security.
Management and Payment of Contributions
Social Security recalls that “the exact amount to be paid is calculated monthly, which can be adjusted against the initial forecast (e.g. in situations of disability for work due to illness)”.
“ The beneficiary will always be notified via the Social Security Portal on the creation of the new contribution obligation. To consult and manage your payments, users have immediate consultation tools on the Portal through the Payment and Debt Menu > Current Position (see) > Values to be paid ", explains the body.
- Separator Current Contributions: Consultation of amounts within the payment deadline in the current month.
- Separater Contributions in Delay: Consultation of values of previous months already exceeded, including their interest on late payment.
“ Through these functionalities, the Independent Worker has full autonomy to select the amounts he wants to pay and issue the respective payment documents, ensuring a rigorous and efficient management of his obligations to Social Security”, explains Social Security.
