Recibos verdes first year: the social security holiday and the two traps around it

In your first year on recibos verdes you normally pay no social security at all: coverage starts on the first day of the 12th month after you open activity, and until then nothing is charged. The catch is that your first real bill is built from the receipts of the last quarter before coverage starts, at a moment when that money is often already spent.

This page walks through that first year as a model. The freelancer in it is hypothetical: someone who opens activity in January 2026, bills foreign clients for services and uses the simplified regime. Every rule comes from a public source listed below, checked on 26 September 2026. It is not tax advice.

When does social security start on recibos verdes?

Social security starts on the first day of the 12th month after you open activity, if this is your first self-employed activity. That is the rule in the Segurança Social practical guide for self-employed workers (version 1.09, published 12 January 2026). Its own example: activity opened in January 2023, coverage from 1 January 2024.

Three details matter:

1. The guide says you are registered in the regime from day one, even while you pay nothing. The Tax Authority sends your data to Segurança Social automatically when you open activity.
2. If you are restarting an old activity rather than opening your first one, coverage starts on the first day of the month you restart. There is no holiday.
3. You can ask to start earlier, by ticking the option on a quarterly declaration in January, April, July or October. You then pay the 20 euro monthly minimum from the start of that month.

For our model, activity opens in January 2026 and contributions start on 1 January 2027.

Is there a quarterly declaration during the exemption year?

The official guide ties the quarterly declaration to workers who must pay contributions: once you are covered, you declare the previous three months by the last day of January, April, July and October. Before coverage starts, the guide lets you file one to start early, and it sets the base at 20 euros until your first declaration.

Your Segurança Social Direta account shows your own status and the date coverage takes effect. Check it once after opening activity rather than relying on a blog, this one included. The same guide notes that a late declaration can now be filed online until the end of the month before the next window, and that missing a required one is a minor offence that can bring a fine.

Which quarter sets your first contribution?

The first declaration after coverage starts sets your first bill, and it covers the quarter before. The guide says so plainly: the declaration filed by 31 January covers October, November and December. In our model that is the last quarter of the exemption year, October to December 2026.

The calculation, from the same guide:

1. Relevant income is 70 percent of your service receipts for the quarter.
2. The monthly base is one third of that relevant income.
3. The rate for self-employed workers is 21.4 percent.
4. The base applies to the month of the declaration and the two months after it.
5. The monthly base has a floor of 20 euros and a cap of 12 times the IAS, which is 6,445.56 euros in 2026.

Here is the model with 13,500 euros of receipts from October to December 2026, which is 4,500 euros a month:

Contributions are paid between the 10th and the 20th of the month after the one they relate to, so January's 674.10 euros falls due between 10 and 20 February 2027. In effect the rate is about 15 percent of service receipts (21.4 percent of 70 percent), which is the figure Portutax also uses.

Do you pay income tax in your first year of recibos verdes?

Yes, but far less than later, and the bill arrives the following summer. Under the simplified regime, 75 percent of service income is taxable. Portutax and Taxclara both describe a reduction for new self-employed workers: 50 percent in the first year of activity and 25 percent in the second. In practice that means about 37.5 percent of receipts is taxable in year one, about 56.25 percent in year two and 75 percent from year three.

The first year's income goes on the Modelo 3 return, filed between 1 April and 30 June of the next year, with any tax due by 31 August when the assessment is issued by 31 July (PwC Worldwide Tax Summaries, reviewed 24 July 2026). So in our model, 2027 is the first year in which monthly contributions and an income tax bill exist at the same time.

On withholding: since January 2025 the rate on recibos verdes for the professions in the Article 151 table is 23 percent, down from 25, under the 2025 State Budget (Law 45-A/2024). It applies when the client is a Portuguese entity with organised accounts. Invoices to foreign clients carry no Portuguese withholding, so the full amount lands and the tax is settled later through the return. For a worked comparison of what a freelancer keeps against an employee, see Portugal tax on 60,000 euros.

What about VAT in the first year?

You can stay out of VAT under the Article 53 exemption if your turnover stays under 15,000 euros a year. The Tax Authority's Ofício Circulado 25062 of 26 March 2025 sets out how it works since the regime changed:

1. When you open activity, you declare an estimate of turnover from your start date to 31 December. There is no longer any conversion to a full year figure.
2. If you end a year above 15,000 euros, you file a change declaration within 15 working days of 31 December and move to the normal regime from 1 January.
3. If you pass 18,750 euros during the year (the limit plus 25 percent), you must charge VAT from the invoice that crosses it.

Our model bills 4,500 euros a month, so it crosses 15,000 euros in April and 18,750 euros in May. Someone with that forecast should not pick the exemption at all. Taxclara gives 23 percent as the standard mainland rate once you leave it.

The two traps, and how to avoid them

Trap one: reading the exemption as a year without social security. It is a year without payments. You are registered from day one, and the receipts of your last exemption quarter decide your first bill. That quarter matters more than any other in the arrangement.

Trap two: spending the money that invoices to foreign clients leave untouched. No withholding, no contributions and a tax return a year away make the first months feel richer than they are. A simple habit works:

1. On the day you open activity, note the date Segurança Social Direta gives for the start of coverage.
2. Move about 15 percent of every service invoice into a separate account for contributions.
3. Set aside a further share for the income tax due the following August, sized with the 2026 brackets in the post linked above.
4. Put reminders for the last day of January, April, July and October, and for 1 April to 30 June for the Modelo 3.
5. Forecast turnover honestly before you choose the Article 53 VAT exemption.
