Understanding Portugal's Social Security System

Last verified: September 2026.

Who this is for

  • You live in Portugal, or are moving here, and will work as an employee or self-employed.
  • You are EU or non-EU and want to know what you pay and what you get back.
  • You worked in other countries and wonder how that counts here.

Not for you if: you only need the number itself. Read Getting a Social Security Number (NISS) in Portugal instead.

Updated September 2026. A new single benefit will replace 13 means-tested support payments from the end of 2026. Pensions and unemployment benefit are not affected.

Portugal's social security system (Segurança Social) pays pensions, unemployment benefit, sick pay, parental pay, and family allowances. If you work in Portugal, you almost certainly have to pay in. Employees pay 11% of gross pay and employers add 23.75%. Self-employed workers pay 21.4% on a share of their income. Registration is free. Your first step is a social security number (NISS), which foreign residents can request online.

Who has to pay in

If you are an employee of a Portuguese employer, you pay 11% of your gross pay. Your employer deducts it and adds its own 23.75%, for 34.75% in total. Your employer registers you and reports your pay each month.

If you are self-employed (on green receipts, recibos verdes), you register yourself and pay your own contributions. The section on self-employed contributions below explains how much.

If you are a company director or manager, you are covered as a member of a company board, with its own rates. Ask your accountant which applies to you.

If you do not work in Portugal, for example because you are retired or live on savings, you do not pay contributions. You can choose to join the voluntary scheme to build up a Portuguese pension. The guide to Joining Voluntary Social Insurance in Portugal explains how.

What it does not pay for

Your contributions do not buy access to the public health service (SNS). The SNS is paid for from general taxes. Foreign residents can use it on the basis of legal residence, whether or not they work. The guide to Healthcare in Portugal covers how to register.

Private health insurance is separate too. It never replaces your social security contributions.

What you get in return

These are the main contribution-based benefits and their core conditions in 2026.

Old-age pension. You need at least 15 years of contributions, in Portugal or another system that pays an old-age pension. The normal pension age is 66 years and 9 months in 2026, and 66 years and 11 months in 2027. A year counts if it has at least 120 days of contributions. The guide to Applying for the State Old-Age Pension in Portugal covers the amount and how to apply.

Unemployment benefit. For employees who lose their job involuntarily. You need at least 360 days of contributions in the 24 months before the job ended. You get 65% of your average past pay, between €537.13 and €1,342.83 a month in 2026. It lasts from 150 to 540 days depending on your age and record, with extra days for long careers. Some self-employed workers with one main client also qualify.

Sick pay. You need 6 months of contributions. Employees are paid from the fourth day off sick, and self-employed workers from the eleventh. The rate starts at 55% of your average pay and rises to 75% for illness over a year. A doctor's sick note (certificado de incapacidade temporária) triggers the payment automatically. A short self-declaration of illness through SNS 24 excuses you from work but does not pay sick pay.

Parental pay. Paid leave for both parents when a child is born or adopted. The guide to Child Benefits and Parental Leave in Portugal sets out the periods.

Family allowance (abono de família). A monthly payment per child, based on household income. It does not depend on contributions.

Many amounts are tied to the social support index (IAS), which is €537.13 in 2026.

How to register

  1. Get a NISS. If you have a Portuguese citizen card, you already have one. Otherwise, foreign residents request it online through the gov.pt NISS service. Your employer can also request it after signing your contract.
  2. If you are an employee, give your NISS to your employer. It registers you and reports your pay.
  3. If you are self-employed, register your activity with Finanças first. Finanças tells Segurança Social automatically. You do not need a separate social security registration.
  4. Set up your online account on Segurança Social Direta, the online portal at seg-social.pt. You log in with your NISS and a password, or with the Chave Móvel Digital.

To request a NISS, have your passport or EU identity card ready, with your residence document if you have one. The online form lists any other documents for your situation.

How self-employed contributions work

The rules apply to anyone registered with Finanças as self-employed.

Your first year is free. If you start self-employment for the first time, contributions begin on the first day of the twelfth month after you start. You can choose to start paying earlier.

You declare every quarter. You submit a quarterly declaration in January, April, July, and October, on Segurança Social Direta. Each one covers the previous three months.

You pay on relevant income, not all income. The base is 70% of your income from services, or 20% of income from selling goods. The rate is 21.4%. Sole traders with a registered business pay 25.2%.

You can adjust the base. When you declare, you can move the base up or down by up to 25%, in steps of 5%.

There is a minimum. If you had no income, or your contribution would be less than €20, you pay €20 a month.

You pay monthly. Payment is due between the 10th and the 20th of the following month.

If you also have a job, you may be exempt as self-employed. This applies if your average relevant self-employed income is under €2,148.52 a month (four times the IAS) and other conditions are met.

If you miss a quarterly declaration, it is an offence and you may be fined. You can still submit it late in the following two months.

The guide to Registering as Self-Employed (Recibos Verdes) in Portugal covers the tax side.

If you work for a company abroad

Which country's system covers you depends on where you work, not your passport or where you pay income tax.

If your employer in another EU country sends you to Portugal for a set period, you can stay in your home system for up to 24 months. Your employer requests an A1 certificate from your home country.

If you work in more than one EU country, you are covered where you live if at least 25% of your work time or pay is there. Otherwise, you are covered where your employer is based.

If you live in Portugal and work remotely, with no posting and no A1, Portugal is usually the country that covers you. If your employer abroad will not register with Segurança Social, you may need to declare and pay as a self-employed worker. Get a written ruling from Segurança Social before you assume either way.

If your employer is outside the EU, check whether Portugal has a social security agreement with that country. The guide to Getting the D8 Digital Nomad Visa for Portugal covers the visa side.

If you worked in other countries

Within the EU, the EEA, and Switzerland, your periods of work elsewhere count towards Portuguese eligibility rules. For example, they help you reach the 15 years for a pension or the 360 days for unemployment benefit.

Each country then pays its own share. If you worked 10 years in Germany and 5 in Portugal, Germany pays for its 10 years and Portugal for its 5. Portugal also has agreements with some non-EU countries.

The guide to How Your Years Working Abroad Count toward a Pension in Portugal explains how to claim.

What is changing

The single social benefit. A law published in August 2026 merges 13 means-tested, non-contributory benefits into one payment, the single social benefit (Prestação Social Única). It includes the social integration income and the social unemployment benefit. It is due to start paying at the end of 2026. People already receiving the old benefits keep their current conditions during the transition.

Contribution-based benefits, such as your old-age pension, unemployment benefit, and sick pay, are not part of this change.

Check your record

Log in to Segurança Social Direta and open your contribution record. It lists every month reported for you. Check it at least once a year, and more often if you are self-employed. Missing months can reduce a future benefit, and it is easier to fix an error while your employer or client can still confirm it.
