Slovakia VAT Requirements

Slovakia expands continuous transaction controls (CTCs)

The modernization of tax and tax controls remains a high priority for Slovakia’s tax authority. The Slovakian Ministry of Finance plans to introduce a continuous transaction control (CTC) scheme, with the aim to lower Slovakia’s VAT gap to the EU average and obtain real-time information about underlying business transactions.   

The Slovakian tax authorities have begun to introduce mandatory business to government (B2G) and government to government (G2G) e-invoicing via the IS EFA platform. Regarding business to business (B2B) and business to consumer (B2C) e-invoicing, there is currently no indication when the mandate will be rolled out, yet the IS EFA platform is planned to also be used for B2B e-invoicing.

Quick facts on Slovakia e-invoicing and VAT reporting


  • Just like in any other EU Member State, e-invoicing is permitted in Slovakia, subject to the buyer accepting the exchange of electronic invoices.
  • While Slovakia today is considered a post audit jurisdiction, a CTC reform is currently underway.
  • The implementation of the mandatory B2G and G2G schedule for the involvement of government and public administration institutions as well as for their suppliers, is expected to happen progressively throughout 2023 and 2024.
  • E-invoices can be stored in another Member State without notification, provided they are available in Slovakia should they be requested by the tax authority.

VAT Reporting

  • Filed either monthly or quarterly and must be submitted through a downloadable form issued by the Slovakian tax authority.
  • Additionally, Slovakia requires the submission of the Slovak Control Statement.
  • Data submitted to the tax authority must be in XML format.

Slovakia's upcoming CTC reform 2022

The Slovakian tax authorities have begun to slowly introduce mandatory B2G and G2G e-invoicing via the IS EFA platform, but there is currently no indication if/when a business to business (B2B) and business to consumer (B2C) mandatory e-invoicing mandate will be rolled out. The previous government decided to freeze the B2B and B2C element of the CTC mandate, with no clear date when it will be implemented, or if the information outlined in the original draft legislation will be maintained in the future.

According to the unpublished CTC draft law, which has been put on hold by the current government, suppliers would have to report invoice data to the tax authority’s e-invoicing platform, IS EFA, before issuing them to their customer.  Similarly, buyers would have to report data from the received invoice.
