Why is A1 crucial?
An A1 certificate confirms that the self-employed person remains covered by the Polish social security system despite providing services in France or Switzerland. This avoids double-payment of contributions and maintains continuity of insurance. However, the absence of this document immediately raises questions: what are the risks without an A1 in France? and what are the consequences of not having an A1 in Switzerland?
Risk scenario: ZUS refused to issue A1 form to a self-employed person
In practice, the situation often looks like this:
-
the entrepreneur submits an application for A1 to ZUS,
-
then he goes to France or Switzerland and starts working,
-
during foreign inspections, officials ask about A1,
-
Meanwhile, ZUS finally refuses to issue the document.
Consequently, the refusal of the A1 form by ZUS means that from the very beginning you must be subject to the local insurance system.
Consequences of the lack of A1 in Switzerland
If the self-employed person works in the B2B formula in Switzerland, the ZUS refusal results in:
-
obligation to pay contributions to the AHV/IV/EO system along with interest ,
-
the risk of self-employment being considered fictitious ,
-
additional costs for the contractor and loss of business confidence ,
-
and in addition, the possibility of imposing administrative penalties for failure to report to cantonal systems , e.g. for breach of obligations under business registration or insurance procedures – penalties range from several thousand CHF upwards.
What are the risks without A1 in France?
Failure to provide an A1 form during an inspection in France not only results in mandatory contributions, but also the risk of significant penalties. In practice:
-
a fine of up to €500,000 may be imposed on the French contractor ,
-
the entrepreneur is obliged to pay contributions in the French system from the date of commencement of work ,
-
additionally, he may incur penalties for failure to comply with formal obligations
-
In many cases, it is also necessary to use the services of a local consulting company , which generates additional costs, as the procedures in France can be complicated and require regular reporting (e.g. to URSSAF, CPAM, DIRECCTE).
Refusal of A1 ZUS form – consequences for the self-employed
To sum up, the lack of A1 is not just a formality, but a real burden:
-
double costs – the entrepreneur loses ZUS protection and must pay contributions in the country where the services are provided,
-
contractual problems – a foreign partner may terminate the contract if the insurance status is not regulated,
-
tax risk – the need to correct settlements both in Poland and abroad,
-
financial sanctions – penalties for failure to submit administrative notifications in France or Switzerland,
-
operating costs – the obligation to cooperate with local law firms or accounting offices in order to properly pay contributions and complete formalities.
How to protect yourself against A1 refusal?
To avoid the above risks, it is worth:
-
prepare full documentation : invoices from Poland, contract with a foreign contractor,
-
sign an annex or a separate agreement specifying the place and period of performance of the services,
-
take advantage of legal consultations – to exclude the risk of false self-employment and adapt the contract provisions to real conditions,
-
Before leaving, check local regulations to ensure that all notifications (e.g. SIPSI, AHV) will be fulfilled.
Summary
As you can see, a ZUS (Social Insurance Institution) A1 form refusal is not only a formality but also a serious threat to self-employed workers and their contractors. The lack of this document means not only the obligation to pay contributions in the country of posting , but also the risk of penalties for failing to comply with legislative procedures and the need to incur additional costs related to working with local entities.
