What has to happen in the first weeks after a Polish company is entered in the KRS?
The tax and statistics numbers (NIP and REGON) are assigned automatically. The company then files form NIP-8 with its supplementary data, such as bank accounts and places of business, within 21 days of the KRS entry, or within 7 days of starting business if that comes first. Beneficial owners go to the CRBR within 14 working days of the KRS entry (AML Act, art. 60).
