Social Security in Portugal: A Complete Guide for Expats

If you work in Portugal – as an employee or on recibos verdesAn electronic receipt that self-employed people issue through the Portal das Finanças. The term is also used for working as a freelancer in general. (green receipts) – you'll pay into Segurança Social, the national social security system. In return you build rights to sick pay, parental leave, unemployment benefit and a state pension.

This guide explains who pays what in 2026, what you get, how the system works for freelancers and foreigners, and how to manage everything online.

In short:

• You need a NISS (social security number) to work. See how to get a NISS.
• Employees pay 11% of gross salary; employers pay 23.75% on top.
• Self-employed workers pay 21.4% on a base calculated from 70% of service income (or 20% of sales of goods), declared quarterly.
• New freelancers are usually exempt for the first 12 months.
• Contributions abroad in the EU/EEA/Switzerland or in countries with a bilateral agreement can count towards Portuguese benefits.
• The key reference value in 2026 is the IAS = €537.13.

How the system is organised

Social security is run by the Instituto da Segurança Social (ISS), with separate institutes in Madeira and the Azores. Contributions are collected by the Instituto de Gestão Financeira da Segurança Social (IGFSS). You deal with all of them through one online portal: Segurança Social Direta.

Healthcare is not part of social security in Portugal – it's provided by the SNS and funded through taxes. You don't need to pay contributions to use public healthcare. See our guide to finding a doctor in Portugal.

Key numbers for 2026

Employees

If you're employed by a Portuguese company:

• Your employer registers the contract with Segurança Social and deducts 11% from your gross pay each month, including the holiday and Christmas payments (subsídio de férias and subsídio de Natal).
• The employer pays an additional 23.75%, so the total contribution is 34.75%.
• Your payslip (recibo de vencimento) shows the deduction.

Example: on a gross salary of €1,500, you pay €165 a month and your employer pays €356.25. For what these deductions leave you with, see gross vs net pay.

Some employment types have different rates – for example, certain contracts for workers with disabilities, non-profit employers and some short-term contracts.

Working remotely for a foreign employer

If you live in Portugal and work for an employer abroad, social security usually follows where you physically work. Inside the EU, the A1 certificate may let you stay in your home country's system for a limited time (for postings or multi-state work). Outside the EU, it depends on bilateral agreements. Many remote workers on the D8 visa register as self-employed or ask their employer to register in Portugal. Get advice early – mistakes here can mean backdated contributions.

How the 11% fits together with IRS withholding and the 14 salary payments is shown in gross vs net salary in Portugal; whether Portugal taxes you at all depends on your tax residency.

Self-employed (trabalhadores independentes)

If you work on recibos verdes, you're a trabalhador independente. When you open activity at Finanças (início de atividade), Social Security is notified automatically.

How contributions are calculated

1. Quarterly declaration. In January, April, July and October, you declare the income you invoiced in the previous three months in Segurança Social Direta.
2. Relevant income (rendimento relevante). Social Security takes 70% of income from services, or 20% of income from selling goods, hospitality and catering.
3. Monthly base. That figure is divided by three.
4. Rate. You pay 21.4% of the monthly base each month for the next quarter, between the 10th and 20th of the following month.

Example: you invoice €6,000 for services in a quarter.

• Relevant income: 70% × €6,000 = €4,200
• Monthly base: €4,200 ÷ 3 = €1,400
• Monthly contribution: 21.4% × €1,400 = €299.60

You can adjust the base up or down by up to 25% in steps of 5%. A minimum contribution of €20 applies in most months when you have low income.

Exemptions

You're usually exempt from paying contributions:

• In the first 12 months after starting activity for the first time.
• If you're also employed and your monthly relevant income as self-employed is below 4 × IAS (€2,148.52 in 2026), subject to conditions.
• If you're a pensioner receiving an old-age pension and working on recibos verdes, in some cases.

Exemptions are not always automatic – check your status in Segurança Social Direta.

Clients' contribution

Companies that buy more than half of a freelancer's annual services pay an extra contribution of 7% or 10% themselves. You don't pay this, but you'll be asked about your main clients.

What benefits do you get?

Self-employed workers have more limited unemployment protection than employees – it applies mainly to "economically dependent" freelancers in specific situations.

State pension

• The legal retirement age is linked to life expectancy and changes every year – it's around 66 years and 9 months in 2026. Check
• You need at least 15 years of contributions for an old-age pension. Years in the EU or in agreement countries can count towards this.
• The amount depends on your contribution history and earnings.

Contributions from other countries

EU, EEA and Switzerland

EU rules coordinate social security across member states:

• You're normally covered by one country at a time – usually where you work.
• Periods of insurance in other EU countries are added together (totalização) to qualify for benefits.
• Each country pays its part of the pension for the years you worked there.
• Forms such as the A1 (posting) and U1 (unemployment periods) prove your history.

Countries with bilateral agreements

Portugal has social security agreements with many countries outside the EU, including Brazil, Canada (and Québec), the United States, Ukraine, Moldova, Cape Verde, Angola, Australia, India, Morocco and others. Coverage varies: some agreements cover pensions only. Check the list on the Segurança Social website.

Segurança Social Direta: managing everything online

Once you have your NISS, set up access to Segurança Social Direta with a password or with the Chave Móvel Digital. There you can:

• See your contribution history and career record
• Submit quarterly declarations (self-employed)
• Generate payment references for Multibanco or bank transfer
• Apply for benefits and track applications
• Update your address and IBAN
• Download a statement of no debt (declaração de situação contributiva regularizada) – often needed for visas, renewals and public tenders

Common mistakes to avoid

• Missing quarterly declarations – Social Security will calculate contributions on its own estimate, and fines can apply.
• Assuming the first-year exemption is automatic – confirm it in the portal.
• Not updating your IBAN – benefits can't be paid.
• Ignoring debts – Social Security debts block residence renewals and can lead to enforcement.
• Working remotely without checking which country should get your contributions.
