Working as an Employee in Portugal: Contract, Social Security, Rights

An employee in Portugal works under a written contract, is registered with Social Security by the employer, and has the same rights and duties as a Portuguese worker. This guide goes through the contract, the trial period, pay, leave, the contributions and income tax taken from your paycheck, and how a job ends, for Americans and Britons who already have, or are about to have, a residence title that allows employment.

It is a reading of official pages, not legal advice. We read them on 18 October 2026. The most recent official notice among them is Despacho 12523-A/2026 of 14 October 2026 on income tax withholding for November, and the most recent guide pages are gov.pt’s pages on working in Portugal (updated 25 September 2026) and on ending a contract (updated 28 September 2026).

Do Americans and Britons have the same rights as Portuguese employees?

Yes, as long as you are authorized to work. Article 4 of the Labor Code says a foreign worker authorized to carry on a salaried activity in Portugal enjoys the same rights and is subject to the same duties as a worker with Portuguese nationality. The gov.pt guide on working in Portugal says the same in its opening line.

Nothing in the pages we read treats a US passport differently from a UK passport. The one place where nationality matters is article 5, paragraph 6, which says the special contract rules for foreign workers do not apply to nationals of an EEA country or of another state that grants equal treatment on free exercise of an occupation. Neither the United States nor the United Kingdom is named there, so we assume nothing and treat the rules below as applying to you. Britons who already lived in Portugal before 2021 are in a different situation, covered in our guide for Britons after Brexit.

This page is about what happens once you have the job. How you get the visa for it is in the work visa guide for employees, and the overview of all work routes is in the pillar on working in Portugal as an American or a Briton. If you work for yourself instead, see freelancing and the independent worker regime; if your employer is abroad, see remote work for a foreign employer: tax and social security.

What must the employment contract say?

Article 5 of the Labor Code sets the content of a contract with a foreign worker. The contract must be in writing and must contain:

Three more points from the same article. You must attach the name and address of the people who would receive a pension if you died in a work accident or from an occupational disease. The contract is made in two copies and the employer gives you one. The employer’s copy carries documents showing the entry and residence rules were met, with copies attached to the other copies. Failing to follow the written form, the duplicate rule or the attached documents is classed as a serious administrative offence.

What else must the employer tell you?

Article 106 lists information the employer must give about the contract. Among the items: your place of work, your category or a summary of duties, how long your vacation is, the notice periods and formal requirements to end the contract, the amount and method of paying your salary, your normal daily and weekly hours and the overtime rules, the work accident insurance policy number and insurer, any collective agreement that applies, the length and conditions of any trial period, your right to continuing training, and the social protection regimes that apply. The gov.pt guide lists most of the same points.

Article 107 sets the timing. The information goes in writing, in one document or several, signed by the employer. A written contract that already contains the information satisfies the duty. Otherwise, when the information is split across several documents, one of them must carry the items that article 107(2) singles out (items a to e, h, i, o and q of article 106(3)), and it is due by the seventh day after performance of the contract begins; the remaining information is due within one month of that start.

Can I get a promise of a contract before I arrive?

Yes. Article 103 says a promise of an employment contract must be in writing and contain the parties’ details and signatures, an unequivocal statement of intent to enter the contract, and the activity and pay. The gov.pt guide says the same.

What types of contract exist, and how long is the trial period?

The gov.pt guide lists the types. The two you will meet most often differ in duration.

The guide also describes “prestação de serviços”, which is a service contract used by independent workers, not employees. If a company offers you one for what looks like a job, read the pillar on how the Labor Code treats that situation.

The trial period is the first stretch of the contract during which both sides assess whether to continue (article 111). On an open-ended contract, article 112 sets it at:

• 90 days for most workers
• 180 days for people in positions of technical complexity, high responsibility or special qualification, in positions of trust, or who are looking for a first job or have been unemployed long term
• 240 days for management and senior staff

On a fixed-term contract it is 30 days if the contract lasts six months or more, and 15 days if it is shorter. A collective agreement or a written agreement between you and the employer can shorten it, and the parties can also exclude it in writing. Article 111 adds that if the employer fails to tell you about the trial period in time under the information rules above, the parties are presumed to have agreed to exclude it. Seniority counts from the start of the trial period.

What are the pay, hours and leave rules?

The gov.pt guide adds that pay can include a base amount plus other items, in cash or in kind such as health insurance or travel costs, and that the in-kind part cannot exceed the cash part unless a collective agreement says otherwise.

Article 263 of the Labor Code provides for a Christmas subsidy equal to one month of pay, paid by 15 December and pro-rated in the year you are hired and the year you leave. The page on diariodarepublica.pt carries a note under article 263 saying it was suspended by Lei 11/2013 from 1 January 2013, and we did not find on that page what replaced it. The tax authority’s November 2026 order, however, refers to the payment of the Christmas subsidy in paychecks, so check your contract or collective agreement for how it is paid to you.

How does Social Security work for an employee?

You need a Social Security number (NISS) to work in Portugal, either as an employee or independently. The gov.pt migrant guide says it can be requested through the “NISS na hora” service if you do not have one. The first step for most newcomers is the tax number (NIF), which the same guide describes as needed to have a job.

For the registration itself the employer does the work. The Social Security Institute guide says the employer must report the new hire through the Social Security portal, declaring the NISS, the type of contract, the base pay and the job, by the start of the contract, or within 24 hours after in exceptional cases such as very short contracts or shift work. If you have no number, one is assigned on the basis of the data you gave the employer. For foreign workers, the employer also provides the documents required by the law on foreigners’ entry and stay. The guide notes that the registration lasts for life, even if you stop working.

What do you pay, and what do you get?

The Social Security Institute guide gives a total rate of 34.75% for most employees, interns, intermittent workers and teleworkers: 23.75% is paid by the employer and 11% by the worker. Some rates are lower or exempt, for example under hiring support measures or for non-profit employers (22.3% for the employer and 11% for the worker in the guide’s table for those). The gov.pt guide says the worker’s 11% is taken automatically from gross salary by the employer.

Once enrolled, the guide lists benefits you become entitled to in these situations: family allowances, unemployment, death, sickness, invalidity, occupational disease, parenthood and old age. It does not state the contribution periods each benefit requires, so check them on the benefit’s own page before you rely on one. If you also hold a second job as an employee, the guide’s FAQ says you pay contributions through each company you work for.

If your employer is not making the contributions, the guide’s FAQ suggests asking the employer first and then Social Security, and contacting the ACT. For health care once you work and contribute, see our guide to healthcare access.

How is income tax withheld from my pay?

The employer withholds IRS (income tax) from each payment under tables published by the tax authority. The 2026 tables, approved by Despacho 233-A/2026 of 6 January 2026 and published in Circular 1/2026, apply to residents of mainland Portugal and have separate tables for people who are unmarried or married with two earners and no dependants (Table I), unmarried with dependants (Table II) and married with a single earner (Table III), plus tables for people with disability.

For Table I, the monthly pay band up to 920 euros has a rate of 0%. The marginal rates then rise by bracket, to 47.17% on monthly pay above 20,221 euros. The circular gives the formula: monthly pay times the rate, minus the amount to deduct, minus the extra amount per dependant. We do not reproduce the full table because it changes each year, so use the Excel tables on the Portal das Finanças or ask your payroll.

Two further points. First, the October 2026 despacho says that since the second half of 2023 withholding follows progressive marginal rates, which brings the tax withheld closer to the tax due in the annual assessment. Second, it applies only 50% of the table amount to pay made in November 2026, to reflect the reduction in IRS rates for 2026, except for monthly pay above the top of the second-highest bracket, and says the ordinary tables apply again from 1 December 2026. The despacho limits this to residents in mainland Portugal, not the Azores or Madeira. This also covers a Christmas subsidy paid in November. If your employer withheld the usual amount in November, it may correct it in the following months up to the end of December.

The gov.pt migrant guide adds that you file an annual IRS return, model 3, and that a foreign resident’s tax obligations are similar to a Portuguese person’s. It does not answer whether you owe tax in the United States or the United Kingdom as well. For Americans the separate US filing is covered in our guide to US taxes from Portugal; the UK side has not been written yet.

How can the job end, and what notice applies?

The gov.pt guide on ending a contract says an employment contract can end by lapse of time or other lapse (caducidade), by agreement (revogação), by dismissal for a worker’s fault, collective dismissal, dismissal for elimination of the position, dismissal for lack of adaptation, or by resignation with cause (resolução) by the worker. When the employer ends the contract, the worker has a right to compensation.

If the employer ends it, article 381 lists the general grounds on which a dismissal is unlawful, among them political, ideological, ethnic or religious motives, a justification declared unfounded, or no proper procedure. For a collective dismissal, article 366 gives compensation of 14 days of base pay and seniority supplements per full year of seniority. The base monthly pay used in the calculation cannot exceed 20 times the guaranteed monthly minimum wage, and the total cannot exceed 12 times the monthly base pay (or 240 times the guaranteed minimum wage when the first cap applies). Article 245 says that when the contract ends you receive pay and subsidy for leave earned and not taken.

What losing the job means for your residence permit is not covered by the pages used for this guide. Read the guide on renewing a residence permit and the AIMA page for your permit type before you act on a notice.

Where do I turn if my employer breaks the rules?

The Authority for Working Conditions (ACT) is the body both gov.pt guides and the Social Security Institute name. The gov.pt guide on ending a contract gives the phone line 300 069 300 on working days, 9:30 to 12:30, and a digital counter on the ACT website. The guide on working in Portugal gives the same number with the hours 9:00 to 12:30, so call in the morning and confirm the hours on the ACT site.

We read these pages on 18 October 2026: the Labor Code consolidated text on diariodarepublica.pt, gov.pt’s guides on working in Portugal, on ending an employment contract and on taxes and Social Security for migrants, the Social Security Institute’s practical guide on registering employees, the DGERT page on the 2026 minimum wage, and the tax authority’s Circular 1/2026 and Despacho 12523-A/2026.
