An acquisition of a company in Poland leads to the establishment of the new controlling body, updates on financial flows, notifications to the required authorities, and then ensuring the continuous realization of day-to-day operations.

It also ensures very high importance for smooth functioning and gaining credibility with partners and clients without fear of penalties or operational blocks. These measures are very important to help ensure that full operational control is achieved and that all internal and external operations of the organization are well aligned with the legal situation at any time.

Change of Shareholder and Director in Polish Company Registers

It is necessary to do all the changes in KRS upon acquisition of a company, particularly updating each of these members and their executive officers. Otherwise, the team’s work would be illegal, or representation from outside would not be possible for the organization. This may cascade down and cause a delay in signing contracts, payments to suppliers, and bank clearings.

Operational steps:

  • Drafting agreements containing the changes and notifying the participants;
  • Formal minutes for the appointments or reappointments of directors or supervisors have been maintained;
  • Prescribed forms and electronically maintained books and records are filled out and entered, for which a fee is then paid;
  • Where transacting through electronic filing is permissible, this should be done in order to expedite the process.

Any error or omission may postpone the new team from completing their task, or even make null and void the completion of the contract annulled by the new team. 

Updating Company Documentation and Corporate Records

After the updates in public files, internal registers must reflect the latest structure of the entity. These updates are essential to ensure legal certainty, smooth operations, and clarity in decision-making.

This would typically mean:

  • Changing the AoA when needed, in accordance with the terms of the transaction, for changes in the voting rights or positions;
  • Keeping the updated list of all parties to the transaction, including key persons with their major executives responsible for the organization;
  • Setting the internal books of account or control sheets to be in alignment with the latest situation to represent the real picture of the team by altering the structure or policy as decided.

Some of these modifications shall take effect only upon registration in public documents and others will be immediately effective internally. It is imperative to have the respective documentation available for audits and financial transactions and operational planning. Internal records also are the basis of negotiations with outside partners for obtaining loans/financing from other sources.

Bank Account Transfer and Compliance Procedures

Once the team managing the entity is officially recognized, it is essential for all banks to be notified so that their access rights and authority of operation are up to date. Of these, Polish banks are known to have very rigid rules on identity verification and fraud prevention. Therefore, it becomes mandatory that only nominated persons deal with the cash amount and other related financial transactions. 

Key steps in this regard:

  • The updated official records with the present officer and participant information;
  • The issuance of new ID cards for newly authorized persons;
  • The bank shall further verify the business activities and sources of income with the planned volumes of transaction for completion by filling up the bank verification forms. 

These may require traveling to relevant places for attending (or even arranging in-person or video meetings) where documents could be gone through.

Tax Registration and Notifications

Notification to fiscal authorities is another critical post-takeover measure. Changes in the operational structure, responsible persons, or operational scope require immediate communication with the local tax office.

Some of the key steps:

  • the notification to the local tax office for any change within 21 days, 
  • taking care that all VAT registrations are in place, 
  • changing PKD codes for any new activities or stopping old ones,
  • securing back TIN and other records in line with the current legal and business case. 

Each careful action on this part will help in attaining financial statements correctly and avoiding any fine or penalty for mistakes. Being prompt also reduces waiting time for sending invoices, receiving refunds, or participating in any tax relief programs that may be available. This makes certain that the organization runs without any hitches.
