Slovakian Ministry of Finance revealed a draft law in 2021 about the implementation of exchanging electronic invoices between all public and private entities gradually. This implementation process is divided into several phases. The Ministry of Finance of the Slovak Republic launched a new electronic invoicing system on 5 May 2022. Before the first phase, the test phase starts in September 2022 to check the prototype of the IS EFA and OpenAPI. The first phase started in January 2023 for public suppliers and included sending e-Invoices to public authorities (B2G) through a platform called IS EFA created by the government. The second phase is expected in 2024 and includes businesses to businesses (B2B), business to customer (B2C), and public entities to customer transactions.
The Ministry of Finance announced that from 1 January 2022 taxpayers will be able to reach a list of bank accounts (domestic and foreign accounts) of VAT-payers for business purposes. Furthermore, each VAT-payer has to inform the government in case of making any changes (creating or removing) in their bank accounts, due to that the list is updated daily. Only the VAT number is needed to find bank accounts, the same as the situation with Polish Whitelist. To verify companies’ bank accounts, there are several methods as follows;
  •  List of the VAT payers with bank accounts published on the tax authority website
  • A list called ”Flat File” in XML format with bank account numbers of VAT payers and used for mass verification of the alignment with the account number
  • An Open Data Portal is a web service that the system can use to access a number of third-party programs.
