Blocking a corporate account in Poland is not just an inconvenience – it is a blow to the financial stability of your business that can paralyse its operations. It is important to understand: an account can be blocked not only due to actual violations but also because of simple carelessness, incorrectly prepared documents, or a transaction that appears too “suspicious”. A missed call from the bank’s support team during a transaction can also lead to a block.

In this article, we have gathered complete information: who in Poland has the right to block your account, for what reasons, and – most importantly – 10 practical tips on how to avoid it. The material is based on current Polish legal requirements and real‑life experience of entrepreneurs.

⚖️ Who Can Block a Company Account in Poland?

Before discussing protection, you need to know the “enemy” by sight. Several entities have the right to block funds in an account, each with its own powers.

1. Blocking by the bank – the most common reason

A distinction should be made between a temporary block of access to the account or internet banking, which may occur due to repeated incorrect entry of a password or SMS codes, and a freeze of funds and the account itself by a bank decision. In the first situation, a visit to the bank or a call to support for identity verification is sufficient. The second case is a more complex procedure.

Under Article 106a of the Banking Law, a bank has the right to block an account on its own if it suspects that the funds in it may originate from criminal or illegal sources (fraud, money laundering). This is done within the framework of internal AML (Anti‑Money Laundering) controls. In 2015, EU Directive 2015/849 was adopted, regulating requirements for financial institutions to prevent money laundering and terrorist financing. It obliged banks to implement enhanced customer due diligence measures and transaction monitoring.

2. Creditors and the court bailiff (komornik)

If the company has unpaid debts, the creditor may go to court. After obtaining a court decision with an enforcement clause (klauzula wykonalności), the court bailiff (komornik) steps in. The bailiff sends an official notice to the bank to seize the account for debt collection. The bank is obliged to block the funds for up to 7 calendar days, after which it must transfer them to the bailiff.

3. State authorities (KAS, US, ZUS)

State authorities that have the power to order the bank to block an account include:

• Szef Krajowej Administracji Skarbowej (KAS) – Head of the National Tax Administration. Can block an account in the event of tax arrears, serious reporting errors (VAT, CIT), or as part of control procedures.

• Naczelnik Urzędu Skarbowego (US) – Head of the tax office.

• Dyrektor Zakładu Ubezpieczeń Społecznych (ZUS) – Director of ZUS, if there are arrears in social security contributions.

• Prokuratura – Public prosecutor’s office, as part of investigative actions.

Important nuance: KAS can apply a short‑term 72‑hour block (without prior notice), against which no appeal is available. This is a preventive measure. If suspicions are confirmed, the block may be extended by a court for up to 3 months.

 

🛡️ 10 Ways to Avoid Account Blocking (Based on Real Experience)

Combining legal theory with practice, we have compiled a list of the most effective preventive measures.

1. 📬 Monitor your email and banking messages daily

This is the simplest and most important rule. The bank will never block an account “silently”. First, it will send a request – by email, via the internet banking system, or by SMS. Always answer calls from the bank, especially when processing transactions.

Tip: Always register the account with a corporate email address, but set up automatic forwarding of all emails from the bank to the personal email of the director and the accountant. This way, you won’t miss an important message even if an employee falls ill or leaves.

2. 🗣️ Notify the bank about counterparties and large transfer amounts

When opening a bank account, it is best to declare all possible jurisdictions the company plans to work with and where it intends to send or receive transfers. For the bank, any deviation from the usual pattern is a red flag. If you start working with a new jurisdiction or expect a large payment, it is wise to contact your relationship manager (opiekun klienta) in advance and inform them.

3. 📈 Financial monitoring – inform about growth in turnover

When opening the account, you indicated the expected annual turnover. If the business takes off and turnover increases sharply (e.g., 3–5 times), the bank’s automated systems may interpret this as an anomaly and block the account.

Tip: Don’t wait for a block. Write to your private banker or support explaining: “Our business is growing rapidly, we have signed new contracts, so we expect an increase in turnover to XXX PLN per month.”

This also applies to large‑sum transfers made immediately after company registration and account opening. Any transfer exceeding the equivalent of EUR 10,000 is automatically flagged for financial monitoring. If the bank has questions about a specific transaction, the account may be blocked pending clarification.

4. 🧾 Always have a “dossier” for each transaction

This is the golden rule for trading companies. For every payment (incoming and outgoing), you should have supporting documents ready. The bank may request them at any time, and you are often given only a few days to respond.

What should be in the dossier:

• Contracts: Supplier agreement and buyer agreement.

• Financial documents: Invoices from the supplier and for the buyer, payment confirmations.

• Transport documents: CMR, bill of lading. Important: Bills of lading can now be checked online. If the vessel called at a sanctioned port, this may cause a block.

• Customs documents: Customs declarations, certificates of origin (if required).

5. 🔍 Check counterparties before the transaction

Take the time to screen a new partner using public databases.

• Check sanctions lists. Doing business with a company whose owner is under sanctions will instantly block your account as well.

• Check registers. See who the actual beneficial owner of the counterparty company is; ensure there are no “problematic” jurisdictions or nationalities involved.

6. 🚫 Do not mix personal and business expenses

A corporate account is for business only. Do not pay for supermarket purchases, buy apartments, or settle restaurant bills with a personal card linked to the company account. For personal needs, open a separate personal account.

7. 🔄 Keep KYC (Know Your Customer) data up to date

Banks are required to regularly update client information (usually once a year). If you change your address, business activity, management board, or beneficial owners – notify the bank immediately. If the bank sends a request to update data, do not ignore it.

Special note: Changing the beneficial owner of a company is treated as opening an account from scratch. The new owner must go through full compliance checks. If they fail, the bank may close the account.

8. 🗣️ Build a personal relationship with your banker

This is a “secret weapon”. If you have direct contact with a personal relationship manager (opiekun klienta) who knows you, they can resolve many issues manually.

9. 📊 Diversify accounts for different business lines

If you have several business activities (e.g., wholesale trade and services), consider opening separate accounts in different banks for each activity. If one account is blocked for reasons related to one activity, the other remains operational, and the business does not come to a complete halt.

10. 👨‍💼 Turn to professionals when things get complicated

If you receive a request from the bank that seems excessive, or if the account has already been blocked – do not try to handle it on your own using Google Translate. A translation error or misunderstanding of the legal context can make the situation worse. An experienced lawyer or consultant knows how to communicate properly with the bank and what documents to prepare to have the account unblocked as quickly as possible.

✅ Conclusion

Account blocking in Poland is not always the result of a legal violation. Often it is a consequence of bureaucratic procedures, automated AML system triggers, or simple carelessness.

Main principles for keeping your account safe:

• Transparency: The bank must understand your business.

• Communication: Respond to requests promptly and fully.

• Documentation: Keep all supporting documents for every transaction.

• Professionalism: Do not skimp on legal assistance for complex matters.

By following these simple rules, you will minimise the risk of a block and ensure financial stability for your business.
