Slovakia advances with mandatory e-Invoicing and e-Reporting in 2027
EDICOM accredited as an e-Invoicing and e-Reporting provider in Slovakia
Slovakia is moving forward with the implementation of its e-Invoicing system and Continuous Transaction Controls (CTC), and EDICOM has been officially accredited as a service provider by the Financial Administration.
This recognition confirms that EDICOM fully complies with Slovakia’s e-Invoicing and e-Reporting requirements, enabling businesses to seamlessly adapt to evolving tax regulations with confidence and efficiency. Through a single integration, companies can manage their electronic invoicing operations in Slovakia while aligning them with a broader, global compliance strategy.
Backed by extensive expertise in international CTC and e-Invoicing initiatives, EDICOM helps organizations stay ahead of regulatory changes, streamline financial operations, and ensure consistent compliance across Slovakia and other key markets.
Electronic Invoicing in Slovakia
Slovakia is accelerating the digital transformation of its invoicing system through the gradual implementation of mandatory electronic invoicing and e-Reporting. This reform will represent a major change for companies operating in the country, as they will need to adapt their invoice issuance, receipt, and exchange processes to a model based on structured electronic documents and the digital transmission of tax information to the Tax Administration.
The current roadmap foresees B2B electronic invoicing requirements taking effect in January 2027, while the system will continue to evolve in alignment with the European Union’s VAT in the Digital Age (ViDA) initiative, aimed at harmonizing electronic data exchange and the reporting of intra-community transactions.
To achieve this, Slovakia is developing an ecosystem built around four key pillars: IS EFA, as the cornerstone of the national system; Peppol, as the interoperable network for exchanging electronic documents; EN 16931, as the European electronic invoicing standard; and e-Reporting, which will automate the communication of tax information to the relevant authorities.
B2G and G2G e-invoicing: System already operational via IS EFA
Since April 2023, Slovakia has gradually implemented mandatory electronic invoicing for transactions between companies and public entities, as well as between government institutions. This initiative places the country within the European framework for transparency and efficiency in public procurement.
These transactions are managed through the IS EFA (Informačný Systém Elektronickej Fakturácie) platform, designed to ensure compliance with the European standard EN 16931. This structured format enables automated invoice processing, reducing errors and manual intervention. With this measure, Slovakia aligns with European policies aimed at achieving greater transparency and efficiency in public procurement.
B2B e-Invoicing and e-Reporting: Mandatory implementation set for 2027
In January 2022, Slovakia proposed a voluntary B2B electronic invoicing system, but mandatory implementation was postponed indefinitely. This changed in November 2024, when a draft bill was introduced to amend Law No. 222/2004 on VAT, laying the legal groundwork for this transformation.
Slovakia is set to roll out mandatory e-invoicing and e-Reporting as part of its broader digital transformation and tax compliance strategy. The new regulatory framework will redefine how businesses issue, receive, and submit invoice data. The requirement will come into force on January 1, 2027, followed by a transitional period lasting until June 30, 2030.
From that date onward, only invoices containing the information required by the VAT Act—and issued, sent, and received in a structured electronic format suitable for automated digital processing—will be considered valid.
What Is the Five-Corner Model?
One of the most important concepts behind the Slovak initiative is the so-called Five-Corner Model.
Unlike centralized systems such as Poland’s KSeF, the Five-Corner Model distributes responsibilities among different participants.
The five participants are:
| Participant | Role |
|---|---|
| Issuer | Generates the electronic invoice |
| Issuer’s provider | Validates, transforms, and transmits the invoice |
| Interoperable network (Peppol) | Secure exchange channel |
| Recipient’s provider | Receives, validates, and delivers the invoice |
| Recipient | Automatically integrates the invoice into its ERP |
This model aims to preserve European interoperability, encourage competition among technology providers, and reduce the operational burden on businesses.
For multinational organizations, it also offers a significant advantage: a single connection can be used to operate across multiple countries that rely on similar infrastructures.
Implementation phases
From January 1, 2027
As of this date, all businesses will be required to issue, receive, and archive structured electronic invoices (EN 16931) for domestic B2B transactions.
They must also carry out real-time e-Reporting of these transactions to the Tax Administration.
Who is affected?
- Invoice issuers: All VAT-registered taxpayers.
- Invoice recipients: All VAT-registered taxpayers, as well as non-taxable persons engaged in business or economic activities.
From July 1, 2030
Mandatory electronic invoicing and reporting for intra-Community B2B transactions will be introduced, in line with ViDA standards.
This phased rollout provides businesses with additional time to adapt their systems and processes before the full scope of the mandate applies.
While electronic invoicing governs the format and exchange of the commercial document, e-Reporting refers to the electronic submission of certain tax information to the Tax Administration.
Electronic Invoicing and e-Reporting in Slovakia
The digital transformation of Slovakia’s tax system is based on two fundamental pillars: electronic invoicing and e-Reporting. Although both concepts are part of the same tax modernization strategy, they serve different purposes, and businesses will need to prepare for both.
Electronic invoicing refers to the issuance, receipt, and exchange of invoices in a structured electronic format that can be automatically processed by information systems without manual intervention. Unlike a PDF sent by email, an electronic invoice contains data organized according to a recognized standard, facilitating validation, ERP integration, and automated processing.
e-Reporting, meanwhile, consists of the electronic transmission of certain tax information to the Tax Administration. Its objective is to provide authorities with faster and more accurate access to economic transaction data, strengthening VAT control, reducing fraud, and simplifying reporting obligations for businesses.
In Slovakia, the evolution of the national initiative combines both elements to create a digital compliance ecosystem aligned with European initiatives. This will allow companies to exchange invoices more efficiently while also complying with future electronic reporting requirements established by national regulations and the European Union’s VAT in the Digital Age (ViDA) initiative.
How does electronic invoicing work?
Invoices must be exchanged through a certified service provider and issued in a structured format that complies with the European standard EN 16931.
A simple PDF sent by email will no longer meet the requirements. Invoices must be created in a structured electronic format that supports automated validation and processing.
In addition, electronic invoices must be archived for 10 years.
How e-Reporting works
The Slovak model goes beyond invoice exchange. It also introduces mandatory reporting obligations.
Both:
- Issued invoices (sales)
- Received invoices (purchases)
must be submitted to the Financial Administration no later than 15 days after issuance or receipt.
This near real-time reporting model heightens the importance of automation and strong internal controls. Relying on manual processes considerably increases the risk of errors and non-compliance.
Penalties for non-compliance
The regulation states significant financial penalties:
- Up to €10,000 for late, incomplete, or inaccurate reporting.
- Up to €100,000 in cases of repeated violations.
Why early preparation is critical
Slovakia’s decision to adopt a five-corner Peppol model means compliance goes far beyond simply generating an EN 16931-compliant XML file. Businesses will need to:
- Connect to the Peppol network through a certified Access Point.
- Adapt their ERP systems to support the required structured formats.
- Ensure accurate transmission and reporting of invoice data to the Tax Administration.
- Implement compliant electronic archiving in line with regulatory requirements.
