Slovak eInvoicing from 2027 for Foreign Entities
Slovakia is changing the rules. Invoices will no longer be available only as PDFs.
Would you like to first understand what eFaktúra will change in practice
When dealing with foreign entities, it is crucial to correctly determine the company’s status. At the same time, however, it helps to understand the broader context of how eFaktúra will change the issuance, delivery, receipt, and processing of invoices in Slovakia starting in 2027.
Check out this practical overview of what the new requirement means for businesses, processes, accounting, and day-to-day administration.
Electronic invoicing in Slovakia, effective January 1, 2027, does not apply uniformly to all foreign companies. The decisive factor is not merely whether a company does business with Slovakia or has a Slovak VAT ID number. The key distinction is whether the entity merely issues invoices to Slovakia, is a foreign entity registered for VAT under Section 5, or is an entity that is already physically established in Slovakia.
This is precisely where the most confusion arises. Foreign companies often confuse VAT registration with establishment and mistakenly assume that the entire Slovak e-invoicing system automatically applies to them. In practice, this may not be the case.
A Slovak VAT ID number does not necessarily mean the entity is Slovak
Slovak VAT registration alone does not make a company an established entity in Slovakia. If a company does not have a genuine business presence in Slovakia—including staff, operations, or a location from which it manages its activities—it is necessary to carefully assess whether the Slovak e-invoice system applies to it to the same extent as it does to a typical Slovak company.
For foreign groups, headquarters, internal tax teams, and advisors alike, it is therefore important not to start with a technical solution, but rather to correctly determine the status of a specific entity.
Three situations, three different impacts
A foreign entity that only issues invoices to Slovakia
If a foreign company supplies goods or services to a Slovak customer from abroad, this does not automatically mean that it is part of the Slovak eFaktúra system. The decisive factors are an assessment of the specific transaction, the place of delivery, and the supplier’s status.
A foreign entity registered in Slovakia pursuant to Section 5
This group requires special attention. A Slovak VAT ID number and local VAT records do not, in and of themselves, mean that the entity is established in Slovakia. It is precisely in this category that it is important to distinguish between administrative registration and an actual business presence.
An entity established in Slovakia
If a company has a physical presence in Slovakia—stable operations, staff, or a location from which part of its business is managed—the situation is considerably more straightforward. In such cases, starting in 2027, eFaktúra will generally cease to be a marginal issue and become a practical operational requirement.
Status first, then technology
The biggest mistake is often trying to address software, workflow, and technical implementation before it is clear which category the entity actually falls into. With eFaktúra, it is not enough to know that a company has a Slovak customer or a Slovak VAT ID number. First, you must determine whether it is a non-established foreign entity, an entity registered under Section 5, or a company that is already physically established in Slovakia.
The next steps depend on that.

Frequently Asked Questions
Basic Extension
The decisive criterion is not just the Slovak VAT ID number
A Slovak VAT ID number is an important identifier, but it does not in itself mean that a foreign entity is established in Slovakia. When dealing with Slovak e-invoices, it is always necessary to assess whether the entity is merely registered for VAT or has an actual business presence in Slovakia.
Registration under Section 5 is not the same as establishment
A foreign entity registered in Slovakia under Section 5 may have a Slovak VAT ID number and fulfill its local VAT obligations, but it is not necessarily an entity established in Slovakia. In practice, these are often companies that have their registered office, accounting, and management in another country and handle only VAT registration and related administrative matters in Slovakia.
Income Tax and eFaktúra are not the same test
The fact that a foreign entity files an income tax return in Slovakia may indicate a stronger connection to Slovakia, but this alone does not automatically determine the entity’s status for e-invoicing purposes. For eFaktúra, it is necessary to consider, above all, the entity’s status under VAT rules and the question of its actual establishment in Slovakia.
Real-life situations
Invoicing to Slovakia does not yet require the use of a Slovak e-invoice
A foreign supplier doing business with a Slovak customer does not automatically become part of the Slovak e-invoice system. The decisive factors are, in particular, the type of transaction, the place of delivery, and the supplier’s legal status.
Reverse charge cases must be assessed on a case-by-case basis
In the case of cross-border transactions under the reverse charge mechanism, the situation will often not automatically fall under Slovakia’s mandatory e-invoicing regime. However, even in such cases, we recommend evaluating the specific model, not just the name of the mechanism listed on the invoice.
An established entity generally has a more direct impact
If a company in Slovakia has a genuine business presence—stable operations, staff, or a location from which it conducts part of its business—eFaktúra must be treated as a real operational matter. In such cases, it is usually necessary to address not only the formal obligation but also the selection of a delivery service provider, internal workflows, and integration with accounting or ERP systems.
Organizational and Technical Impact
The technology itself is not the first step
Implementing e-invoicing software, workflows, or archiving solutions only makes sense once it is clear that a particular entity actually falls under the relevant regime. For multinational groups, the most effective approach is to begin with a legal and tax assessment and only then address the technical implementation.
The Slovak tax regime may have an impact even without maintaining local accounting records
Even if a foreign entity does not maintain accounting records in Slovakia, it may want to determine whether its Slovak VAT registration or local transactions require adjustments to its invoicing processes, reporting, or internal communication with its headquarters.
A one-size-fits-all approach for the entire group may not be the right one
The fact that one foreign company within a group is registered for VAT or established in Slovakia does not mean that the same rules automatically apply to the other entities. Each entity must be assessed separately based on its actual operating model.
Our Work for International Partners
We assess the actual impact, not just the formal status
When it comes to Slovak e-invoices, we help distinguish between cases involving a genuine operational obligation and those involving merely an administrative link to Slovakia. In practice, this means that we verify the entity’s registration, the nature of its operations, its organizational structure, and where decision-making and business operations actually take place.
The result should be a clear recommendation
The goal is not to create another layer of uncertainty. The goal is to provide foreign partners with a clear conclusion as to whether they need to fully implement the Slovak e-invoice system, whether it is sufficient to monitor developments on an ongoing basis, or whether the risk is currently more formal than practical.
