Between percentages, coefficients and relevant income calculations, it\u2019s easy to feel lost. However, submitting this declaration correctly is essential to secure your rights and avoid fines or interest.<\/p><p>This article explains what you need to know to comply with confidence, without diving into technical details that will soon be covered in a more practical way.<\/p><p><strong>Who must file the quarterly declaration<\/strong><\/p><p class=\"translation-block\">The quarterly declaration is mandatory for <strong>all self-employed workers covered by the Portuguese Social Security self-employment regime<\/strong>.<\/p><p>However, there are situations where no contributions are due:<\/p><ul><li class=\"translation-block\"><strong>Workers not yet required to contribute<\/strong>, such as those who started their activity less than 12 months ago;<\/li><li class=\"translation-block\">Workers who also have salaried income and earn less than four times the IAS (2,090\u20ac in 2025).<\/li><\/ul><p>Even in these cases, it\u2019s important to monitor your Social Security status, as the exemption may end automatically once the conditions are no longer met.<\/p><p><strong>When it must be filed<\/strong><\/p><p class=\"translation-block\">The declaration must be filed <strong>four times a year, by the last day of January, April, July and October.<\/strong><br>\nEach submission must include the income obtained in the previous three months.<\/p><p>For example:<\/p><ul><li class=\"translation-block\">In <strong>October<\/strong>, you declare income earned in <strong>July, August and September<\/strong>.<\/li><\/ul><p class=\"translation-block\">Even if you had no income during the quarter, you <strong>must submit the declaration with a zero value<\/strong>.<\/p><p><strong>What to include in the declaration<\/strong><\/p><p>In the quarterly declaration, self-employed workers must indicate:<\/p><ul><li class=\"translation-block\">The <strong>total income earned<\/strong> during the previous quarter;<\/li><li class=\"translation-block\">The <strong>type of income<\/strong>  (services, sales, hospitality activities, etc.).<\/li><\/ul><p class=\"translation-block\">Based on this information, Social Security automatically calculates <strong>the relevant income<\/strong>, applying the <strong>coefficient for each activity<\/strong>:<\/p><ul><li>70% for service provision;<\/li><li>20% for production and sales of goods;<\/li><li>10% for accommodation and similar activities.<\/li><\/ul><p>The contribution rate is then applied to the relevant income (normally, <strong>21,4%<\/strong>).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c56784f elementor-invisible elementor-widget elementor-widget-litho-blockquote\"

benefits, such as parental allowance;<\/li><li>Interest charges on undeclared amounts;<\/li><li>Delays in regularising your contribution record, which can affect access to grants or benefits.<\/li><\/ul><p>In cases of repeated non-compliance, Social Security may consider the worker in default and refuse to issue a certificate of good standing.<\/p><p><strong>Practical example<\/strong><\/p><p>Imagine a self-employed worker who earned 3,000\u20ac in service income between July and September.<\/p><ul><li>Applicable coefficient: 70% \u2192 2,100\u20ac of relevant income.<\/li><li>Monthly contribution: 21.4% on one-third of the relevant income \u2192 around 150\u20ac per month.<\/li><\/ul><p>The quarterly declaration simply reports these figures, which form the basis for calculating the contributions payable in the following months.<\/p><p><strong>Additional useful information<\/strong><\/p><ul><li>If you adjust your contribution amount (increase or decrease by up to 25%), the change takes effect in the next quarter.<\/li><li>If you have income from different categories (e.g. services and sales), you must separate them correctly in the declaration.<\/li><li>The declaration is submitted exclusively online via Seguran\u00e7a Social Direta, under \u201cSelf-Employed Workers\u201d.<\/li><\/ul><p><strong>Conclusion<\/strong><\/p><p class=\"translation-block\">Submitting your quarterly declaration is essential to keep your Social Security record up to date and avoid unpleasant surprises.\nStill, many freelancers find it difficult to understand how the values are calculated, which coefficients apply, and how to fix errors.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element
