E-invoicing compliance and regulatory updates - Greece

Electronic Invoicing in Greece

Is e-invoicing mandatory in Greece ?

In 2019, Greece adopted the transposition of the Directive 2014/55/EU, making it mandatory for the Central Government to receive e-invoices. Later, in 2020, a regulation concerning the semantic model and architecture of e-invoicing for Business-to-Government (B2G) transactions was adopted. Peppol Bis 3.0 was chosen as the mandatory EN compliant format.

The Interoperability Centre is responsible for receiving all supplier and contractor e-invoices through the certified e-invoice Service Providers and the Peppol network. The Centre routes these invoices to the competent contracting authority. 

Furthermore, the Hellenic Government has instituted a B2G e-invoicing mandate, scheduled for initiation in September 2023. The implementation of this mandate will unfold progressively, contingent upon the specific public administration to which the invoice is directed.

The phased timeline for compliance is as follows:

Key Deadlines:

1. By the conclusion of 2023, several major public authorities will be mandated to adhere to the electronic invoicing mandate.
2. Commencing on the 1st of January 2024, all primary-level public administration entities will be obliged to conform to the stipulated e-invoicing regulations.
3. As of the 1st of June 2024, nearly all public authorities will become subject to the mandatory B2G e-invoicing requirement.

B2B:There is no mandate in Business-to-Business (B2B), but there are regulations working in that direction.

From July 1, 2021, all invoice senders must upload their invoices to a Government platform - myDATA. Following the joint announcement by the Ministry and Independent Authority of Public Revenue (AADE), companies must proceed in a phased manner to the electronic transmission of their documents to myDATA and the interconnection of their cash registers with 'taxisnet' from October 2021. Phases are based on the type of accounting books and annual revenue.

The mandatory transmission of business documents to the myDATA platform began on 1 October 2021 for businesses with double entry accounting books with turnover over 50.000 Eur.

Due to the COVID pandemic, the transmission for remaining businesses and the interconnection of tax mechanisms with AADE was postponed from the original implementation date of 1 July 2021 to 1 Nov 2021 for all companies.

Suppliers within Greece must submit electronic invoices, either through their own connection to the Peppol network, or via an e-invoice service provider such as Basware.

The Greek Public Administration requires e-invoice service providers to have a Peppol certified access point, be certified by AADE, and have successfully performed the necessary operational tests with the General Secretariat for Information Systems of Public Administration (GGPSDD). These requirements also apply to foreign suppliers who have the obligation to appoint a Tax Representative in Greece.

E-delivery, initially introduced under Law 4308/2014, now requires businesses to issue and transmit e-delivery documents using myDATA ERP solutions or e-invoicing services.

The adoption of e-delivery occurs in two phases:

1. Phase One (December 2024) mandates issuing and sending e-delivery documents via myDATA, including recipient notification using their VAT number.

Phase Two (April 2025) requires monitoring goods in transit, reporting real-time changes, and verifying goods' quality and quantity

Introduction of the e-delivery system

The implementation of the e-delivery reporting system will take place in two phases with each phase requiring the users fill in different fields:

• Phase one: issuer’s and recipient’s data, delivery document number, MARK & QR code, date of issuance, commencement of the delivery, places of loading and delivery, type of goods and quantity, etc. Implementation date: 1 December 2024.
• Phase two: exact time, transportation means, reloading data (if any), Intrastat codes, transporter’s VAT numbers, etc. Implementation date: 1 April 2025.

Non-compliance may result in penalties, 100€ per non-transmitted document on a daily basis and up to 20.000€ on annual basis.

Archiving

The standard archiving period is 5 year, starting from the end of the year in which the deadline to submit tax return expires.

Archiving does not need to be digital and paper is acceptable. However, legibility and data must be preserved, ensuring the authenticity of the origin and the integrity of content.

Archiving abroad can be accepted as long as certain requirements are adhered to.

Our advice

As many other southern European countries, Greece has now adopted an invoice clearance model.

For buyers with a significant volume, we advise automating the invoice receiving and sending process by connecting to the governmental platform through the Basware Network and our local partner. It avoids manual key-in or downloading from governmental portals.
