Poland corporate onboarding: documents, risks and rules

For a Polish customer, the first decision is whether the counterparty is a company or an individual entrepreneur. That determines the relevant register and the ownership evidence that makes sense. KRS company records can establish representation, while CEIDG addresses individual businesses. Keeping that distinction clear prevents a negative search or a tax identifier from being mistaken for a complete onboarding conclusion.
Which rules apply
Poland's Act of 1 March 2018 on counteracting money laundering and terrorist financing governs obliged institutions within scope. Customer due diligence includes customer and beneficial ownership identification, assessment of the relationship and ongoing monitoring. KRS corporate particulars and the Central Register of Beneficial Owners (CRBR) are separate evidence sources. The relevant coverage, released information and current access conditions should be established for the entity and purpose.
The duties follow the onboarding firm's location, regulatory status and service. An overseas firm applies its own relevant regime to this customer. Ordinary commercial counterparties can also use these records for risk assessment without having the same duties as regulated firms.
For EU members, Regulation (EU) 2024/1624 generally applies from 10 July 2027. It should not be treated as replacing the current national AML framework for a 2026 onboarding decision.
Documents commonly requested
The starting file should reflect the legal form and the proposed relationship. These records answer complementary questions:
| Evidence | What the reviewer looks for |
|---|---|
| Current KRS information or appropriate CEIDG record | Legal person or entrepreneur, form, status and registered identity |
| Full KRS information and relevant corporate documents | Changes explaining older officers, names or governance |
| Representation provisions and delegated authority | Required signatures, registered proxies and mandate scope |
| Current ownership records and group chart | Holdings, voting rights and corporate ownership layers |
| Permitted CRBR and individual identity evidence | Relevant natural persons and supporting verification |
| Filed financial documents and commercial evidence | Reporting period, trading explanation and expected funding |
Registry records establish facts within their stated scope. Current ownership records, identity evidence and mandates may need to come from the client or another permitted source. Keeping those origins visible helps explain differences and the extent of independent corroboration.
The risks behind the paperwork
KRS and NIP can look alike without meaning the same thing. Both identifiers have ten digits, but KRS identifies a court-register entry and NIP serves a tax role. REGON has another statistical purpose. Labelling the numbers keeps the company match assessable. An individual entrepreneur may instead be recorded in CEIDG; absence from KRS does not establish that their business is unregistered or justify inventing a corporate shareholder structure for it.
The representation rule may require signatures together. A management board entry needs to be read with the registered method of representation. The relevant arrangement may require two board members or a combination involving a commercial proxy. Prokura entries also have their own conditions. A shareholder or employee acting under a delegation needs evidence linking the instruction to an authorised grantor, rather than relying on a familiar name elsewhere in the file.
Visible shareholders may not form a complete ownership list. KRS disclosure depends on the legal form and the entries required for it. The holders visible in an extract should therefore be assessed within that scope. Current company-held records can supply missing holdings and later changes, while corporate holders require further tracing. CRBR information should be compared with the ownership explanation, including voting and other control rights, so discrepancies lead to specific evidence requests.
Filed financial documents should be matched to the same entity and the relevant reporting period. The business explanation then connects expected transactions to suppliers, customers and funding sources. Tax status and sector authorisation have separate official sources; neither should be assumed from the company's continued registration or its recorded corporate purpose.
How the Fill Easy email bot helps
An approved organisational sender can request available registry documents from agent@fill-easy.com, using prose, a table or an attached spreadsheet. Include the company identifier and required documents:
Please retrieve current and relevant historical KRS information, available corporate documents and filed accounts for [company name], KRS [number], with NIP [number] as a cross-check. Reference: [case reference]. Please include a summary report and confirm availability, price and expected turnaround.
The agent replies with item statuses, asks for clarification where needed, and returns retrieved PDFs in the same thread. Results carry their source, retrieval time and request ID. An optional summary references the documents. Availability, price and expected turnaround are confirmed at acceptance.
This helps the team collect and reconcile the registry evidence. Client-held records and individual identity evidence still follow the appropriate process, while the reviewer resolves remaining gaps and makes the onboarding decision. See the Mailbox workflow for the email process.
