If you’re an employer, entrepreneur, or worker planning to operate across borders in the EU, the A1 Certificate is one of the most important documents you’ll need. It ensures you don’t pay double social security contributions and keeps you compliant with EU law.
In 2025, the rules remain the same, but employers and workers are focusing on faster approvals to avoid delays in assignments. Here’s your step-by-step guide to getting the A1 form in Portugal quickly and correctly.
What Is the A1 Certificate?
The A1 Certificate confirms which country’s social security system applies when an employee or self-employed worker is temporarily working in another EU/EEA country or Switzerland.
It prevents double contributions by ensuring workers remain insured only in their home country.

Why It Matters in 2025
- Faster processing is crucial – delays can hold up contracts and mobility.
- Compliance checks are stricter – EU authorities expect correct filings.
- Workers need protection abroad – healthcare, pensions, and benefits continue uninterrupted.
Steps for Fast Approval in Portugal
- Prepare documents early – include contract details, assignment length, and proof of employment.
- Apply before departure – don’t wait until workers are already abroad.
- Use digital submission – where available, submit applications online for speed.
- Check assignment length – standard approval is up to 12 months, extendable to 18.
- Work with experts – advisory support ensures no mistakes that cause delays.

In Portugal, the A1 Certificate is issued by Segurança Social.
