Greece government will implement mandatory electronic invoice reporting as of 1 January 2021. To this end, Greek Independent Authority of Public Revenue (A.A.D.E) created the myDATA portal.


Through myDATA (my Digital Accounting and Tax Application) platform, AADE will:

• monitor all the company transactions that generate revenue and expense, and

• record the Tax and Fiscal results.


It contains two electronic accounting books (ebooks) belonging to the taxpayers. Taxpayers report summary documents, their classifications and accounting settlement documents to the myDATA in electronic XML format. Consequently the electronic books; Summary Book and Analytical Records Book are updated.


1. The Analytical Records Book: is where the data of revenue/expense documents

are recorded, the classification of the documents is done and finally the accounting results to achieve the Tax and Fiscal result for every year is recorded

2. The Summary Book, where the company results are shown on monthly and yearly

Basis. 


What types of the documents must be reported by issuers and recipients?


There are three main types of documents:


  1. Summary Documents: The Issuer is obliged to send the summary of all the documents she issues (B2B-B2G-B2C-Wholesale and Retail). The recipient sends the summary of the documents received only in the below cases:

  1. Retail documents. 

  2. Documents for purchase of goods and services from companies non-liable to follow Greek Accounting Principles (e.g. individuals, foreign companies outside Greece)

  3. Documents for purchase of goods and services from an issuer liable to Greek Accounting Principles only if the submission deadline was missed by the Issuer.

  1. Classifications: Classification of summary documents into sales/purchase of goods and services. Both issuer and recipient are responsible to send.

  2. Accounting Settlement Records: The documents to reach tax results such as payroll, depreciation and income/expense settlement documents. Again both issuer and recipient are responsible to send.


Who is obliged to use MyData tax platform?


All companies keeping accounting records according to the Greek Accounting Standards will have to comply. Non-resident companies will be out of scope.


Reporting Methods to myDATA


You can send the summary documents:

  1. directly from your ERP accounting software

  2. through a service provider, 

  3. manually filling the online form (for small number of documents), or 

  4. using electronic tax registers (only for retail documents).


You can send the classifications and settlement documents:

  1. directly from your ERP accounting software, or 

  2. manually filling the online form.


When does the mandatory e-invoice sending start?


The real time reporting of electronic invoices starts on 1 April 2021 for companies using ERP systems to issue the e-invoices or manually creating the invoices on the portal. The invoices issued in the period 01.01.2021-31.03.2021 shall be transmitted not later than 31.10.2021 The deadline for sending the settlement account records will be the submission deadline for submitting income tax declarations. Exceptionally payroll statements will be sent until the submission deadline of withholding tax return on salaries and wages.


Is e-invoicing & e-bookkeeping mandatory in Greece?


MyDATA eBooks regulation is not going to change the current invoicing process between suppliers and recipients. Taxpayers can continue paper and PDF invoicing. This regulation will mandate the reporting of electronic XML format documents which contain summary data of invoices, credit notes, delivery notes, retail receipts and other accounting documents suppliers or recipients issue. So it is important to

understand invoicing and myDATA eBooks e-invoice reporting will be separate processes in Greece. 


How would SNI be helpful with the Mydata E-book system?


SNI myDATA SAP add-on will:

  • handle reporting of all the e-documents issued in SAP automatically in real time.

  • extract invoice data from myDATA to the SAP system. 

  • Transfer unique invoice numbers (MARKs) to the expense documents

  • Classify and send all the revenue/expense documents. 

  • Transmit all the accounting settlement documents for tax and fiscal results. 


One software is able to do all the steps and ensure you stay compliant. Moreover, it saves significant time and costs with your business processes.


An end-to-end solution: all three major components of digital tax reporting in a single SAP add-on:


First, it starts from the required data retrieval. Then, this retrieved data needs to be mapped and processed in order to prepare it as the tax authority’s requested format. Finally, this converted data shall be submitted to the Greece MyData portal. SNI add-on solutions cover all these three major components in one single SAP add-on solution which you would not need to look for any other external third party employment.
