As of October 1, 2018, preparation and filing of financial statements must take place in electronic form.
Corporations
Under the Accounting Act, preparation of annual financial statements by the statutory deadline in commercial companies is the responsibility of the management board members. Auditing of the annual financial statements is mandatory for joint-stock companies and for limited liability companies that meet at least 2 of the following requirements: (1) employ at least 50 people (2) and that have total balance sheet assets of more than EUR2.5 million or (3) net revenue from the sale of goods and services and financial operations for the financial year of more than EUR5 million at the end of a financial year. Company's books must be drawn up in Polish language, however, there is no statutory rule as to where the books must be kept (in any case, Polish tax authorities must be informed about the place where the books and records are kept).
As of January 1, 2022, instead of the past requirement of signing the financial statements only with an electronic signature by all management board members, it is sufficient for an esignature to be affixed by at least one person who is a member of the management board, provided that the signing of the financial statements in XML format takes place after the other members of that body have made declarations that the financial statements meet the requirements provided for in the Polish Accounting Act, or have refused to make such declarations (in electronic form or in writing).
Partnerships
With respect to partnerships, only those partnerships that meet at least 2 of the requirements listed above have the duty to subject their financial statements to an audit.
Branches
Branches of foreign banks, credit institutions, insurance companies and investment companies are obliged to submit their financial statements to an audit. This obligation also applies to branches that meet the aforementioned requirements regarding the value of assets, the volume of operations and the number of people employed.
