If you've woken up too sick to work in Portugal, you're probably wondering how the paperwork actually works. Portugal Sick Leave (Baixa Médica): SNS and Social Security Process can feel confusing at first, especially if you're new to the country or unfamiliar with how the SNS (Serviço Nacional de Saúde) and Segurança Social talk to each other. The short version: a doctor issues a certificate confirming you can't work, that certificate gets sent electronically to Social Security, and , if you qualify , you receive a daily payment called subsídio de doença while you recover. This guide walks through each step, from diagnosis to payment, including what to do if you can't get a same-day appointment.
What Baixa Médica Means and How It Works
"Baixa médica" is the Portuguese term for medical sick leave. It's not just a note excusing you from work , it's a formal document, the CIT (Certificado de Incapacidade Temporária, or Temporary Incapacity Certificate), that legally records that a doctor has assessed you as unfit for work for a specific period.
makes the Portuguese system different from a typical "fit note" in other countries: the certificate is generated digitally and linked directly to your Social Security file through the ATCUD tracking code. This means your doctor doesn't hand you a paper to deliver by hand in most cases , the declaração de incapacidade temporária is transmitted automatically once issued, so Social Security already knows you're on baixa médica Portugal before you even tell your employer.
There are two broad categories of baixa médica:
- Baixa por doença natural , ordinary illness unrelated to work
- Baixa por acidente de trabalho , a workplace accident, which follows a separate insurance process through your employer's work-accident insurer, not standard sickness benefit
This article focuses on the first type, which covers the large majority of everyday sick leave cases.
Eligibility and Contribution Rules: Who Qualifies for Sick Pay in Portugal
Not everyone who gets a sick note automatically receives paid sickness benefit. Social Security has its own eligibility test, separate from the medical assessment.
To qualify for subsídio de doença as an employee, you generally need:
- At least six months of registered contributions to Social Security (they don't need to be consecutive, but they must fall within a set reference period)
- A valid CIT issued by a doctor confirming incapacity for work
- Active worker status at the time the illness begins
For self-employed workers (trabalhadores independentes), the rules are stricter and often overlooked by other guides. You must have been paying Social Security contributions for at least 12 months, and , importantly , those contributions must be up to date, with no gaps, at the moment your baixa médica starts. If you've been irregular with payments, or you recently switched from employee to freelance status, it's worth checking your contribution record on the Segurança Social Direta portal before assuming you're covered. Self-employed workers also face a longer waiting period before payments begin, which we cover below.
There is also a waiting period (período de espera) built into the system: the first 3 days of sick leave are typically unpaid for employees, unless it's your third episode of sick leave within the same calendar year, in which case payment can start from day one. Self-employed workers usually face a slightly different, and sometimes longer, threshold, so it's worth confirming your exact case with Social Security directly.
How the SNS Issues Your Baixa Médica (Portugal Sick Leave)
This is the part most people actually need help with in the moment: how do you get the certificate? Here's the realistic, step-by-step process.
- See a doctor. This can be your family doctor (médico de família) at your local SNS health center, an SNS urgent care unit, or a private doctor. All are legally allowed to issue a valid CIT.
- The doctor assesses your condition and decides how many days of incapacity to certify , commonly 3 to 15 days for common illnesses, though it can be longer for more serious conditions.
- The certificate is transmitted electronically to Social Security through the national system, generally within 24 hours, using the ATCUD code for tracking and validation.
- You receive a copy (paper or digital) confirming the dates covered , keep this for your own records and for your employer if requested.
The catch, and the reason so many people search for help online, is that SNS appointment availability varies wildly by region. In smaller towns or during flu season, getting a same-day appointment with your médico de família can take days , time you don't have when you're too sick to work and unpaid until the certificate exists.
This is the gap that online medical certificate services fill. A licensed doctor can assess your symptoms remotely and issue a valid medical certificate for work in Portugal without you needing to sit in a waiting room. If you're an expat, tourist, student, or simply can't get an SNS slot in time, getting your baixa médica online through a service like Get Medical Certificate means you're not stuck losing pay just because the clinic is booked out. It's a GDPR-compliant, fast route to the same kind of documentation, often available in your own language.
The Social Security Process for Sickness Benefit: Pay Amount and Duration
Once your CIT is on file, Social Security calculates your subsídio de doença based on your average earnings, not your full salary. Here's roughly how it breaks down:
| Duration of Sick Leave | Percentage of Reference Earnings Paid |
|---|---|
| Up to 30 days | 55% |
| 31 to 90 days | 60% |
| 91 to 365 days | 70% |
| More than 365 days | 75% |
Your "reference earnings" are calculated from your registered pay in the months before the illness, not your gross salary at the time you fall sick. Low earners may qualify for a small supplement to bring payments closer to a minimum threshold, so it's worth checking your specific calculation on the Segurança Social portal rather than estimating from your payslip alone.
Payments are usually made monthly, by bank transfer, directly from Social Security , not from your employer, who continues to owe you nothing in salary for the certified sick days (though some collective agreements or company policies top up the difference voluntarily).
Maximum duration for ordinary illness is generally up to 1,095 days (three years) , though continued eligibility after long stretches usually involves periodic medical review to confirm the incapacity for work is still valid.
Employer and Employee Obligations During Baixa Médica
Once you have your certificate, there are a few practical things to sort out on both sides.
As the employee, you should:
- Notify your employer as soon as reasonably possible, ideally the same day, even if the electronic transmission to Social Security happens automatically
- Keep a copy of your CIT and any renewal certificates if your illness extends beyond the original dates
- Avoid working (including remote or freelance work) during the certified period, since this can void your benefit and create legal problems
- Attend any follow-up assessment if Social Security or SNS requests one
Employers, meanwhile, are expected to:
- Record the absence correctly in payroll, marking it as unpaid sick leave (since Social Security, not the company, pays the benefit)
- Avoid penalizing or dismissing an employee for legitimately certified sick leave, which is protected under Portuguese labor law
- Respect the employee's right to return to the same role once the certified period ends
Disputes are rare when the CIT is properly issued and transmitted, since the electronic link between SNS and Social Security removes most of the "he said, she said" that exists in countries relying on paper notes.
Fast Alternatives When You Can't Reach an SNS Doctor
Portugal's public health system is reliable, but it's not always fast. If you're traveling, self-employed with deadlines piling up, or simply can't get a same-week appointment, a licensed online doctor consultation is a practical backup. These services typically involve a short video or written consultation, a real medical assessment, and , when appropriate , a properly issued certificate you can submit the same way you would an in-person one.
This matters especially for international workers and travelers who may not speak Portuguese fluently or who need documentation quickly for an employer abroad, a university, or an athletic event requiring a fitness certificate. Get Medical Certificate was built for this kind of situation: quick, licensed, GDPR-compliant certificates issued online, in plain language, without the wait.
Frequently Asked Questions
How long does baixa médica last in Portugal?
It depends on your condition. A doctor typically certifies anywhere from a few days to several weeks at a time, with renewals possible if you're still unwell. Long-term cases can extend up to three years under continued review.
Do I get paid from day one of sick leave?
Usually not , there's a 3-day waiting period for most employees before Social Security payments start, unless it's your third sick leave episode in the same year.
Can self-employed workers get sick pay in Portugal?
Yes, but only with at least 12 months of up-to-date Social Security contributions, and the waiting period is often longer than for standard employees.
What is the fastest way to get a sick note in Portugal?
