Formularz A1 confirms that a worker posted to another EU country remains subject to the Polish social security system. The document follows from EU social security coordination, in particular Regulation 883/2004.
Najważniejsze informacje
A1 is needed by every person posted to werk in an EU country, regardless of position. It applies to lassers, fitters, operators, voormannen, QC and supervisors. The application is submitted electronically to ZUS, and processing usually takes from several to thirty days.
Wymagania in practice
The form validity is linked to the posting period and generally does not exceed 24 months. Without A1, the werker may become subject to insurance in the country where werk is performed, generating high costs and formal risk for the company.
Ryzyka i terminy
Belgium requires Limosa notifications, the Netherlands uses notification systems for posted workers, and Germany has its own requirements for temporary work and AÜG. A1 is the basis, but never the only entry document.
Hoe Staffeo helpt
Staffeo handles A1 for posted werkers, monitors deadlines and completes documenten before mobilization. This avoids nervous document searches at the site gate or explanations that a document is still in progress.
Waarom is A1 financieel zo belangrijk?
Without the A1 form, the werker may be considered subject to social insurance in the country where werk is performed. In practice this means a risk of double contributions, arrears, penalties and disputes with local institutions. With a crew of a dozen people, the problem can stop mobilization or significantly increase project cost.
Welke gegevens zijn nodig?
Preparing the application requires werker data, posting period, country and place of werk, employer information and the posting basis. It is important that A1 dates match the real werk period and project documenten.
Rol van Staffeo bij detachering
Staffeo connects A1 with the rest of the process: local notifications, accommodatie, transport, VCA/SCC requirements and werking-time reporting. The candidate knows when they leave, where they sleep, whom to call on arrival and which documenten to carry.
A1 en andere toegangsdocumenten
A1 does not werk in isolation. When posting, it must be combined with the contract, local notification, tax documentation, policy or health insurance confirmation, professional certificaten and HSE requirements.
Meest voorkomende fouten bij detachering
The most common problems are late applications, no updates when project dates change, confusing the country of werk, incomplete werker data or assuming one document is enough for every rotation.
Wat moet vóór vertrek met de klant worden afgesproken?
Before mobilization, confirm the exact site address, start date, expected rotation end, overtime settlement model and the person responsible for admitting werkers to werk.
