Ah I see, thanks for checking that. We're lucky you're 'ere!
An application filled in Polish includes:
· PESEL, if the trader has the number,
· the designation of the trader, i.e. full name and surname and - if any - the name of the company,
· the subject of the economic activity, in accordance with Polska Klasyfikacja Działalności (Polish Classification of Activity),
· NIP (numer identyfikacji podatkowej - tax identification number), if the trader has the number,
· the localisation and the residence address, the address of delivery as well as the address which is adequate for carrying out the activity and if the activity is implemented out of the localisation and residence address - also the address of the main localisation where the activity is carried out and the branch if any was established,
· the information of the marital property system or the lack of it,
· the information of the agreement of civil company if any was established,
· the data of a permanent legal agent entitled to carry out the trader's business - if any was established,
· the precise date of establishing the activity which is essential for other institutions (e.g. Tax Office) and legalising the activity.
The fee for submitting the application is 100 zl and if the application refers to change in the register the fee is 50 zl. The application for removing from the register is free of charge. The act of registering should take place within maximum of 7 days. Then the confirmation of registering is delivered within 14 days from submitting the application.
I'm going to assume the above refers to what Jon said. (However, a fee of 50zł is definitely payable for all traders per PKD code added later.)
Any business that is registered with KRS/the courts (all businesses? some businesses? VAT reg businesses? I don't know) need to pay 300PLN to close their business

Well, this page below seems to say it's everyone who has to pay 100PLN, even individuals going self-employed. I'm sure the accountant told me there's no fee, just as you have. But...

Registration procedures
The process of establishing business in Poland should start with the selection of the most appropriate legal form (see: Forms of enterprises), and with signing the Articles of Association or Deed of Formation. The fees, depending on the selected forms of activity, are varied.
Establishment of individual enterprise (enterprise run by a natural person) or registered partnerships are the cheapest.The registration of the business in such case costs PLN 100.The Economic Activity Record (Ewidencja Działalności Gospodarczej) is managed by the local government of the community where the business is to be located.
