Characteristics of Electronic Invoicing in Ireland

In line with European guidelines, the use of electronic invoicing in Ireland is mandatory within the B2G (Business-to-Government) sector, meaning all public administrations are required to accept and process electronic invoices. However, for public suppliers, the use of this format remains voluntary.

In the case of electronic invoicing between private companies (B2B), it is currently not mandatory. The issuance of electronic invoices or any other digital document depends on a mutual agreement between the parties involved.

The branch responsible for overseeing and managing tax-related matters, including electronic invoices, is the Irish Tax & Customs, which serves as Ireland's tax authority.

Mandatory Use

All public institutions must be able to receive and manage electronic invoices. The issuance of e-invoices by suppliers is voluntary. 

Invoice Format

The national format is PEPPOL BIS. However, the public administrations have defined their own CIUS-CEFACT format. 

Electronic Signature

Applying an electronic signature to electronic invoices is not mandatory, thus simplifying the issuance and submission process.

Invoice Archiving

According to tax legislation, all electronic invoices must be stored for a minimum period of 6 years.
