Slovakia VAT Requirements

Slovakia introduces continuous transaction control

The modernisation 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.

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.
  • First introduced in a draft law published by the Ministry of Finance, e-invoicing in B2G transactions is gradually becoming mandatory for private sector suppliers as well as public sector buyers. Preliminarily, the law is proposed to enter into force in early 2022, when the system is supposed to become mandatory for B2G transactions.
  • 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.
  • Businesses who accept cash payments must use an ‘online cash register’ that connects directly to the tax authority system.
  • Data submitted to the tax authority must be in XML format.

Slovakia's upcoming CTC reform

The envisaged CTC system, Electronic Invoice Information Systems (IS EFA, Informačný systém elektronickej fakturácie), will become mandatory for B2G transactions from early 2022.

Full details of the upcoming CTC system are not yet available, but the proposed legislation is expected to be published early 2022. The preliminary statements announced by the authorities in February 2021 aim to introduce mandatory real-time invoice reporting for all types of transactions (including B2B and B2C) by 2023.

The incoming CTC mandate will require businesses to report invoice data to the tax authority prior to issuing the invoice to their trading parties. Trading parties must then in turn report receipt of the invoice. Data must be sent either through certified accounting software or the government portal.

Mandated E-Invoicing rollout dates

  • Until December 2022: Development and testing of IS EFA for B2B and B2C transactions
  • Early 2022: Mandatory e-invoicing for B2G
  • 2023: Mandatory e-invoicing for all other transaction types (B2B, B2C) is expected
