Who is obliged to use e‑Invoicing in Slovakia

There is no e-invoicing obligation in Slovakia yet – neither for B2B nor for B2G, but public entities must be able to handle the receipt of e-invoices when the supplier decides to send them in this way. As part of the test phase, effective from June 1, 2022, all suppliers can issue electronic invoices for public authorities. The Slovak government plans to introduce a new CTC (Continuous Transaction Controls) system for B2B transactions, which will become mandatory from 2024.

E-invoicing process description

For the submission of invoices,CTC system named IS EFA (Informačný Systém Elektronickej Fakturácie) supports two main methods:

  • Automatic upload directly from the ERP system of the taxpayer (large and medium-sized companies)
  • Manual upload in the EFA user application (small companies subject to VAT)

For foreign suppliers of Slovakian public authorities, a separate procedure for e-invoicing applies. They have to send an e-mail with the invoice attached to an official government e-mail address

White list’ of bank accounts

Since January 2022, the Slovakian financial administration has been publishing a list of all bank account numbers officially registered by companies. This list is updated daily. Any payment to settle an invoice must be made to a bank account contained in the list. If an unregistered account is used, the invoice issuer’s VAT obligation will become applicable to the invoice recipient as well. The list of registered bank accounts can be checked on the Internet. Likewise, it is possible to download it as flat file which can be used to automate the validation process.
