The first year of freelancer social security is a deferred start

Open an activity on 15 March 2026 and a lot of pages will tell you that the first year of social security is free. The Ordem dos Contabilistas Certificados practical guide of August 2026 describes something narrower. There is a framing — an enquadramento — in the independent workers' regime. On a first enrolment, its effects start on the first day of the 12th month after the activity begins. That is a deferred start of contributions. It is not a formal exemption, and it is not free forever.

The quarterly machine in the freelancer social security guide is what runs after effects have begun and a declaration has set a base. Until then, read this page. Invoices, VAT and withholding carry on from the first recibo verde. IRS Jovem, if you qualify, can change the tax bill. This page does not treat it as a rule that switches contributions off.

15 March 2026 means effects from 1 March 2027

Count in months, not in a vague year. The activity begins in March 2026. The first month after that month is April 2026. The twelfth month after it is March 2027. Effects start on the first day of that month: 1 March 2027, unless you ask for an earlier start. They do not start on 15 March 2027. The day you clicked inside March does not push the effect date off the 1st.

1. 15 March 2026: first enrolment. You can issue invoices from the start date you registered.
2. From March 2026 through February 2027 the framing is not yet producing contribution effects. The OCC guide describes a framing whose effects have not started. Blogs that call this an isenção are using the wrong word.
3. 1 March 2027: effects begin, if you did not opt in sooner. Until the first quarterly declaration that sets a base, the OCC describes the contribution as the €20 minimum in article 165(1). The guide has long described that €20. This page is citing that description.
4. After that declaration, the quarterly rules take over. The amount and the due date are on Segurança Social Direta. When a quarter mixes months before and after the effect date, read the extract for which declaration is first.

A restart is a different sentence in the same OCC guide. A restart of activity produces effects on the first day of the restart month. If 15 March 2026 is a restart rather than the first time you enrol, effects start on 1 March 2026, not on 1 March 2027. Know which sentence is yours before you count twelve months.

You can ask for the effects to start earlier

The request is made at the quarterly-declaration moments: the filings due by the last day of January, April, July and October. The rule the OCC states is that effects then run from the first day of the month after the request. The same guide notes that Segurança Social Direta practice, for an on-time filing in one of those four months, can bring the effects into the declaration month itself. Confirm the start date on the account extract. Do not pick it from a paragraph.

Opened on 15 March 2026, you might use the July 2026 declaration, covering April to June, to ask for an earlier start. The month-after sentence points at 1 August 2026. The note about an on-time filing points at the possibility of July 2026 itself. The extract names the day. A late filing has no substitute date on this page.

If you stop, the clock pauses

If the activity stops during those first 12 months, the clock pauses. It continues on a restart only if the restart falls within the following 12 months. A stop on 30 June 2026, then a restart in February 2027, sits inside a window of that length. A restart in August 2027 does not. This page does not decide whether the window ends on 30 June 2027 or on the first day of the next month, and it does not compute the resumed effect date. A longer gap is a question for the extract and the OCC checklist.

The €20 is a minimum after effects begin

Article 165(1) is where the contributory code puts a minimum contribution of €20. The OCC guide has long described that figure as the contribution after effects have begun and before the first quarterly declaration sets a base. It is not the contribution during the months in which effects have not started. It is not a reduced rate you choose on an invoice. Once the declaration exists, the base is the quarterly one: one third of the quarter's relevant income, at 21.4 percent in the general case, with the ceiling at 12 × the IAS. That whole sum is the other guide.

Employees have a separate exemption, with a cumulative test

There is a different rule for people who are also employees. The OCC guide says it requires cumulative conditions. Two of them can be stated in numbers. Average employee pay has to be at least 1 × IAS, measured on the previous quarter. The IAS in 2026 is €537.13, so that limb is €537.13. The exemption covers relevant monthly income below 4 × IAS. Four times €537.13 is €2,148.52. The full test is article 157 of the contributory code, and the OCC checklist is longer than the two figures this paragraph states. This page will not add conditions it is not sure of. Failing one condition means contributions are due on the freelance income.

Three employee months of €1,800 average €1,800, which clears the €537.13 pay limb as the OCC states it. Relevant income for services is 70 percent of service revenue. €2,148.52 / 0.70 = €3,069.31 of service invoices, to the cent. €3,000 × 0.70 = €2,100, below the line. €3,100 × 0.70 = €2,170, above it. Clearing both limbs still leaves article 157 as the test. If one condition fails, contributions are due on the freelance income.

A contract plus invoices is a different year from invoices alone, which is why the employee or freelancer comparison is not the whole story once you are both. The employee exemption is about contributions on the freelance relevant income. It does not rewrite the employment payslip.

The tax side does not wait for March 2027

Withholding and the article 31 coefficient apply to the invoices you issue. Ten invoices of €2,000 for article 151 services, at 23 percent and with no VAT in the example: revenue €20,000, withholding €4,600, cash from clients €15,400, simplified taxable income €20,000 × 0.75 = €15,000 before the 15 percent expense test. The rate on €15,000 is in the brackets guide. None of that waits for March 2027. A 15 March start does not create twelve months of 2026 revenue. Count the invoices of the tax year.

The calculator always charges the month you type

The independent calculator always charges social security on the month you type. It has no switch for the 12-month deferral and no switch for the €20 floor of article 165(1). A €2,000 service month at 21.4 percent shows €2,000 × 0.70 = €1,400, then €1,400 × 0.214 = €299.60, including a March 2026 entry on the timeline above. That figure is the steady-state sum from the other guide. It is not the OCC timeline on day one, and it is not the €20 minimum.
