General information
Slovakia has decided to introduce a central e-invoicing system called Informačný Systém Elektronickej Fakturácie (IS EFA).
Pursuant to IS EFA – Technical outline, there are different modules in the e-invoicing setup:
- EFA Gateway: responsible for communication with the taxpayer ERP system, in particular, to allow receipt of supplier invoices.
- EFA Processing: responsible for processing electronic invoices.
- EFA Delivery: responsible for delivery of invoices to customers.
- Analytical System: responsible for performing checks on reported invoices.
- EFA User Application: responsible for generating electronic invoices and managing them.
- Invoice disclosure: responsible for invoice disclosure for B2G and G2G scenarios.
There are two main methods of entering invoices in the IS EFA system:
- Automatic upload directly from taxpayer ERP dedicated to medium and large taxpayers.
- Manual upload using EFA User Application dedicated to small taxpayers.
The implementation process of e-invoicing is divided into two phases:
- From January 2022, e-invoicing through IS EFA becomes mandatory in B2G, G2G, and G2B transactions.
- From January 2023, e-invoicing through IS EFA becomes mandatory for all other transaction types, including B2B scenarios.
