On 31 December 2020, in a last-minute change, the Greek government once again postponed the go-live date of myDATA to April 2021. This announcement had been anticipated and came as a great relief to Greek taxpayers who were concerned about being ready for the previous go-live date of January 2021.

The first quarter of 2021 will offer an opportunity for additional training and adoption of the new CTC framework.

In particular, by virtue of Ministerial Decision A.1300/2020 (amending decision 1138/2020 published in June), the mandatory transmission of required data to the myDATA platform will be postponed to 1 April 2021. Data of the first quarter of 2021 must also be transmitted no later than 31 October 2021 so that a complete overview of a full year is provided on myDATA e-books.

In addition, the Ministerial Decision has introduced some further changes including:

• The full roll-out timeline has been updated. Transmission of data of Q1 2021 is mandatory with different deadlines for income, expense and payroll (end of October, November and December respectively). Transmission of data of Q4 2020 remains voluntary.
• For wholesale and retail transactions which don’t require cash registers (Φ.Η.Μ), a new data transmission method has been introduced which is an IAPR application for the issuance and transmission of required documents. The relevant data is transmitted in real-time.
• The transmission timeline for retail transactions is defined depending on whether they require the use of cash registers or not.
• Exceptionally for 2020 and 2021, certain sectors such as utilities and credit institutions can opt to transmit the required data cumulatively. The latest Decision has additional sectors on this list including telecommunications, tolls and the Bank of Greece.
• New categories of taxes, duties, deductions and other fees are introduced in Appendix 2 of Decision 1138/2020. The Appendix lists all fields of the document types in scope, where these new taxes and fees must be reflected.

It remains to be seen if this additional postponement of the myDATA go-live date will enable Greek taxpayers and relevant stakeholders, as well as the IAPR -the Greek tax authority – itself, to be appropriately and timely prepared for the new CTC requirements.
