Previously, Greece was planning to mandate the implementation of myDATA on 1 April 2021.   However, considering the effects of COVID-19, the Greek Ministry of Finance and the Greek Independent Authority for Public Revenue (IAPR) announced that the mandate of myDATA would be postponed to 1 July 2021.   Companies still have to submit the accounting data generated during the first half of 2021 to the authorities through the myDATA platform by 31 October 2021.
