The Greek tax office, AADE, is planning to mandate the implementation of the myDATA electronic platform for taxpayers from 1 July 2021. This would create a standardised e-book schema, supplemented with 'e-invoices', with monthly automated submissions. These direct digital filing requirements will be adopted for VAT, corporate income tax and withholding taxes.
Note - whilst termed e-invoicing by the Greek authorities, this model is actually closer to transaction reporting seen in Spain's SII and other EU countries recently. There is no Greek requirement to send e-invoices to the customer; only to report transaction details to the tax office.
The new timetable for submitting electronic VAT information to AADE is below. For 2021, date may be transmitted within 5 days of the issuance on mandated invoice, but at latest by the 20th of the month following.
E-invoices by businesses
Retail sector reporting
Accounting e-ledgers
The above digital records will be transmitted automatically to the AADE, via the myDATA portal. The filing deadline is set to the 20th day of the following month.
Taxpayers have four options to submit their e-invoices and e-books:
AADE anticipates being able to match and validate taxpayers VAT transactions with their counterparties' submissions to detect errors and fraud. This will be done live via myDATA, and discrepancies will be immediately returned via myDATA.
The plans will include electronic cash registers for retailers. For businesses without electronic accounting systems, there will be a manual upload option.
The Greek tax authorities will produce two sets of accounting records for each filing taxpayer from the above information:
The Greek government certifies electronic invoice service providers. Only certified providers may issue B2C or B2C e-invoices on behalf of taxpayers, and then transmitting the data to the tax authorities myDATA REST API in the approved invoice format. They may also transmit the invoice data to customers.
Providers must have demonstrated robust invoice creation, storage and retrieval systems to guarantee the integrity of invoices. They must also be Greek resident, and meet financial stability tests. Invoice data may be stored elsewhere in the EU.
