Accounting in Poland has its own specifics. The main task of an accountant is to keep accounting books and maintain accurate accounting records of all business transactions. Based on these records, an annual financial report is prepared in compliance with accounting standards and submitted to the tax office and the company register (KRS or CEIDG) by 30 April of the following year.
Polish accountants also prepare the main tax reports: Income tax (CIT) – monthly or quarterly, Value Added Tax (VAT) – monthly. Individual entrepreneurs submit an annual PIT report to the tax inspectorate. Both monthly and annual reports are also submitted to ZUS. If the entrepreneur is VAT-registered, monthly VAT reports are required. Our services are designed to cover every business, including those with specific needs related to running a business.
