Update to VAT Act e-invoicing based on EU standard
The amendments to the VAT Act will introduce an obligation for payers to issue and receive invoices in the prescribed electronic format, effective from 1 January 2027. An electronic invoice will only be considered an invoice that contains the information required by the VAT Act and that is issued, sent and received in a structured electronic format that allows for its automatic and electronic processing. In order to ensure the uniformity of electronic invoices concerning payers, an obligation will be established to issue invoices in a structured format that complies with the European standard for electronic invoicing and the list of its syntaxes established by Directive 2014/55/EU of the European Parliament and of the Council of 16 April 2014 on electronic invoicing in public procurement.
With effect from 1 January 2027, an obligation will be introduced to report data from issued and received electronic invoices for domestic transactions. Invoice data will be reported electronically in a manner that is consistent with the manner established in Article 4 of the Directive, which regulates the submission of data from electronic invoices for cross-border transactions within the EU. The aim of the above changes is to digitize the entire process from the supplier’s creation to the customer’s processing of the electronic invoice, as well as the subsequent sending of data from the electronic invoice to the financial administration so that this entire process is automated with a minimum of manual intervention, resulting in a significant shortening of the processes related to the receipt of invoices and their subsequent processing (e.g. elimination of entering data from paper invoices into the system).
E-invoicing to cut tax fraud
The measure on the part of the state will contribute to the effective fight against tax fraud, has the potential to reduce tax gaps in both value added tax and corporate income tax, and improve tax collection. By making data from electronic invoices available in real time, the financial administration will be able to process input data needed to identify the fulfillment of tax obligations in a timely manner, or to set up certain control mechanisms within the framework of risk analysis to prevent fraudulent actions, with possible simultaneous adjustments to selected tax administration institutes. The above assumes a change in end-to-end services and related information systems of financial administration, as well as building capacities using new analytical tools for processing data obtained from electronic invoices.
On the part of business entities, business operations will also be simplified and the efficiency and quality of the business environment will improve. At the same time, the speed of data transfer, guarantee and credibility of communication will increase by introducing standardization in the field of electronic invoicing due to the current diversification of the environment (different levels of standards used, an environment sensitive to emerging errors, etc.).
In addition, in accordance with the aforementioned objective of the Slovak government to make the fight against tax evasion more effective, with effect from 1 January 2026, changes will be made in the area of tax registration in order to eliminate avoidance of the registration obligation, as well as in the area of deregistration, in order to prevent the re-entry of persons who have demonstrably actively and knowingly participated in fraudulent transactions into the VAT system.
