How to Start a Business in Poland with a Foreign Partner
Starting a business in Poland with a foreign partner is a fully legal and practical solution widely used by Ukrainian citizens and nationals of other EU countries. Polish law allows companies to be established even when one or more founders are physically located outside Poland.
However, this business model involves certain legal, technical, and organizational considerations that should be addressed at the planning stage. A properly structured business model and correctly prepared documentation play a key role.

Business in Poland with a Foreign Partner
This cooperation model allows foreign partners to be legally involved in Polish companies without their physical presence, provided that all formal requirements are met.
Key Conditions for Starting a Business with a Foreign Partner
The most common legal form for cooperation with a non-resident partner is a spółka z o.o. (limited liability company), as it allows:
- the involvement of foreign shareholders;
- remote company registration;
- clear definition of ownership shares and management powers.
The physical presence of the partner in Poland is not required.
You can learn more about the registration procedure in our dedicated guide — company registration in Poland (sp. z o.o.).
Registration of a Spółka z o.o. via the S24 System
When establishing a company together with a foreign partner, registration is usually carried out through the electronic S24 system, which enables online submission of documents.
Electronic Signatures and Identification
A partner residing abroad may use a qualified electronic signature or other electronic signatures recognized in Poland.
A PESEL number is not required to register a spółka z o.o.
Documents of a Foreign Shareholder
It is mandatory to submit a declaration of foreigner status, as well as correctly prepare the company’s articles of association and the list of shareholders.
If all documents are properly signed, the company is registered through the standard procedure without delays.
Participation of a Partner as a Sole Proprietor in Poland
If a partner plans to operate as a sole trader (jednoosobowa działalność gospodarcza), it should be noted that registration in CEIDG without a PESEL number is not possible.
In such cases, we recommend an initial legal consultation to select the appropriate cooperation model and avoid potential tax risks.
Partner Due Diligence Before Starting Cooperation
Before launching a business, it is recommended to conduct a legal and financial due diligence of the foreign partner, including verification of:
- absence of criminal convictions;
- absence from sanctions lists;
- business reputation and financial stability.
