Important Update for Businesses in Poland!
A draft regulation by the Minister of Finance is set to elevate the SAF-T Poland accounting file (JPK_KR) from optional to mandatory for Corporate Income Tax (CIT) settlements. This regulatory change under the Corporate Income Tax Act aims to enhance transparency and streamline the efficiency of tax audits, ensuring comparability between submitted records, financial statements, JPK_VAT including VAT returns and e-invoicing data from the KSeF system. The consultation phase is currently underway, and the regulation is slated to take effect on January 1, 2025.
