Clear timeline for the introduction of e-invoicing in Slovakia
Voluntary testing
Companies can voluntarily test sending and receiving e-invoices via Peppol. The ideal time to prepare systems and processes.
Mandatory e-invoicing
All VAT payers must issue e-invoices for domestic B2B and B2G transactions. Invoices pass through Peppol with automatic reporting to the Financial Administration of the Slovak Republic.
Extension and simplification
The obligation will extend to cross-border transactions. The abolition of the VAT control statement is also planned — the e-invoice will replace it.
What is an e-invoice?
An e-invoice is not a PDF. It is a completely new way for businesses to exchange invoicing data.
Structured XML
An e-invoice is an XML document (UBL 2.1), not a PDF. Automatically processable by systems without manual re-entry.
Peppol network
Delivered through the verified and secure international Peppol infrastructure — like digital mail for invoices.
Automatic reporting
E-invoice data is automatically reported to the Financial Administration of the Slovak Republic — the so-called 5th corner. No manual reports.
Digital postman
To send e-invoices you need a certified digital postman (Access Point). Fakturuj.si has it included.

Who must e-invoice?
Obligations differ depending on whether you are a VAT payer.
VAT payer
From 1 January 2027, must issue and receive e-invoices for domestic B2B and B2G transactions. You need an invoicing system connected to Peppol and a certified digital postman.
Non-VAT payer
You do not need to issue e-invoices (until 2030). However, you must be able to receive e-invoices — your suppliers (VAT payers) will send them to you via Peppol.
