Portugal’s social security system — Segurança Social — funds pensions, healthcare coverage, unemployment benefit, sickness pay, maternity and parental leave, and family support. If you move to Lisbon and become tax-resident, there is a good chance you will interact with it, whether you contribute, claim, or transfer rights you have already built up elsewhere.
This guide explains how the system works for the three most common expat situations: employees, self-employed residents, and retirees drawing pensions from abroad.
What Segurança Social covers
The Portuguese social security system covers:
- Pensions — old-age, survivors’ and invalidity
- Unemployment benefit — for employees and some self-employed
- Sickness pay — when you cannot work due to illness
- Maternity, paternity and parental leave — paid benefits during leave
- Family allowance — means-tested support for children
- Social inclusion income (RSI) — safety-net benefit for residents on very low income
Access to the public health service (SNS) is separate from Segurança Social — registering with a health centre (centro de saúde) is what gets you into SNS, not paying social security.
Employees — how much you contribute
Employees in Portugal contribute 11% of gross salary to social security, withheld at source. The employer pays a further 23.75% on top. So on a €3,000 gross monthly salary, you see €330 deducted and the employer pays €712.50 separately.
These contributions build up rights to all of the benefits listed above, including a full Portuguese old-age pension after the qualifying period (currently 15 years of contributions for any pension, with a full pension after considerably longer).
Self-employed — the recibos verdes regime
Most expat freelancers, consultants and remote workers operate as self-employed trabalhadores independentes, issuing recibos verdes (green receipts) for their invoices.
Self-employed contributions are:
- 21.4% of a declared contribution base, each quarter
- Base = 70% of relevant quarterly income (or 20% for people supplying goods)
- Minimum quarterly contribution applies if income is very low
- First 12 months exempt if it is your first time registering
The administration is quarterly: you declare income, Segurança Social calculates the base, and you pay by direct debit.
Retirees drawing pensions from abroad
If you move to Lisbon on a D7 visa drawing a foreign pension, you usually do not contribute to Portuguese social security on that pension. What matters is whether your home country’s social security system has a totalisation agreement with Portugal (or is covered by EU Regulation 883/2004 if you are from the EU/EEA/Switzerland).
Under these agreements:
- You do not pay twice on the same income
- Contributions paid in your home country may count towards Portuguese pension rights (and vice versa)
- EU citizens typically use the S1 form to access Portuguese public healthcare, with the home country reimbursing costs
The UK, US, Canada, Australia, Brazil and many other countries have agreements with Portugal. Your home-country social security office can issue the certificate that confirms you are covered at home and should not be charged locally.
NISS — your social security number
Everyone who registers with Segurança Social receives a NISS (Número de Identificação da Segurança Social). You will need it to be paid by a Portuguese employer, to issue recibos verdes, or to claim any benefit.
Getting a NISS requires your NIF, proof of residence and ID. It can be done at any Segurança Social office, usually in a single visit, and is free.
What this means for property buyers
Most buyers we work with do not live in Portugal full-time at the point of purchase. You do not need a NISS or social security registration simply to buy a property. Where it matters is if you plan to spend more than 183 days per year in Portugal, become tax-resident, or work here — in which case Segurança Social becomes relevant alongside Portuguese tax residency.
