Slovakia: The Financial Administration Opens a Seven-Region eFaktúra Conference Program for September 2026 and Reissues Its Official eFaktúra FAQ

Country Update — Slovakia  |  17 August 2026  |  Topic: E-Invoicing / Authority Guidance and Readiness

In August 2026, the Slovak Financial Administration (Finančná správa) opened registration for a program of seven regional conferences on mandatory electronic invoicing, held between September 7 and September 30, 2026, under the title "eFaktúra ako kľúčový nástroj digitalizácie podnikania na Slovensku" — eFaktúra as a key instrument of business digitalization in Slovakia.

The program is delivered by the Financial Administration's leadership and specialists in taxation, information technology, digitalization, and fraud prevention, and is aimed at businesses, sole traders, accountants, and professional associations preparing for the obligation that applies from January 1, 2027. It runs alongside the authority's official eFaktúra question-and-answer document, reference 9/DPH/2025/IM, the most recent published version of which is dated July 7, 2026 and runs to 47 pages.

Background

Slovakia has legislated a domestic structured e-invoicing obligation with a comparatively short lead time. Act No. 385/2025 Z.z., amending Act No. 222/2004 Z.z. on value added tax, introduces mandatory issuance and receipt of structured electronic invoices in domestic business-to-business and business-to-government transactions with effect from January 1, 2027.

The intervening period, from January 1, 2026 to January 1, 2027, serves as a transition period during which use of the new delivery services is voluntary. The model is decentralized rather than clearance-based: invoices are exchanged in a structured format conforming to the European standard EN 16931, in UBL, through Peppol-based delivery, with data reported to the Financial Administration rather than cleared by it in advance.

That architecture makes Slovakia unusual among the newer central and eastern European mandates, most of which have chosen a state-operated clearance platform. It also makes the authority's published guidance more important than usual, because in a decentralized model many of the questions a taxpayer needs answered — which documents are in scope, how corrections work, what happens when a counterparty is not reachable, how the reporting obligation interacts with issuance — are not answered by the platform's behavior and must be answered in text.

Accordingly, the Financial Administration has been running an unusually visible information program. It has published and repeatedly reissued an official FAQ under reference 9/DPH/2025/IM, which has grown from a few pages in December 2025 to 47 pages by July 2026, and it has maintained a dedicated eFaktúra section on the Financial Administration portal. KGT has reported on two earlier developments in this program: the recognition of the Slovak Peppol-based model at EU level, on July 6, 2026, and the ex officio allocation of tax numbers to some 58,000 entities that will need them in order to be addressable under the mandate, on August 11, 2026.

The Legislative Change

There is no legislative change here. Act No. 385/2025 Z.z. and the underlying VAT Act are unchanged; the mandate date of January 1, 2027 is unchanged, and the transition regime for 2026 is unchanged. What has happened is that the tax authority has published an implementation and readiness program, and has continued to develop its official interpretation of the regime through a versioned FAQ.

It would be a mistake to treat that as merely promotional. In a decentralized mandate, the authority's published position on a transitional or borderline question is, in practice, the position a taxpayer will be assessed against, and the FAQ under reference 9/DPH/2025/IM is the instrument through which that position is stated and revised. Its growth from a short document in December 2025 to 47 pages in July 2026 reflects how much operating detail the legislation did not settle. Any Slovak implementation designed against the legislation alone, without reference to the current FAQ version, is being designed against an incomplete rule set.

FAQ versioning is itself a control point. The document is reissued under the same reference number with a new date, roughly monthly through 2026 — versions dated March 3, March 10, March 26, April 24, May 6, May 25, June 12 and July 7, 2026 have been published. An organization that downloaded it once and filed it is working from a superseded interpretation.

Scope

• Conference programme, seven events, all starting at 10:00 with registration from 09:30, each covering one administrative region: Žilina region, Monday September 7, 2026, Château Gbeľany; Trenčín region, Wednesday September 9, Piano Club Trenčín; Prešov region, Wednesday September 16, ZOC Koral, Prešov; Košice region, Thursday September 17, Košice Hotel; Trnava region, Tuesday September 22, Ensana Splendid, Piešťany; Nitra region, Thursday September 24, Agrokomplex Nitra; Banská Bystrica region, Wednesday September 30, Hotel LUX, Banská Bystrica.

• Speakers — drawn from Financial Administration leadership and specialist directorates: Jozef Kiss, President of the Financial Administration; Marcela Hricová, Director General of the Tax Section; Stanislav Pavlovič, Director General of the IT Section; Peter Boháčik, Director General of the Fraud Prevention Directorate; and Juraj Vojtek, Director of the Specialized Digitalization Directorate. The programme is hosted by Daniel Kováč, spokesperson for the Financial Administration.
• Content — presentation of the forthcoming e-invoicing system, available solutions, practical recommendations for preparation, explanation of each party's obligations, technical options, and a question and discussion segment.
• Official FAQ — document reference 9/DPH/2025/IM, "Najčastejšie otázky a odpovede k eFaktúre", latest published version dated July 7, 2026, 47 pages, published on the Financial Administration portal.

Timeline

• January 1, 2026 — start of the transition period. Use of the new delivery services is voluntary.
• Through 2026 — the Financial Administration reissues its official eFaktúra FAQ under reference 9/DPH/2025/IM at roughly monthly intervals; the latest published version is dated July 7, 2026.
• August 2026 — registration opens for the regional conference program.
• September 7 to September 30, 2026 — the seven regional conferences take place.
• January 1, 2027 — mandatory issuance and receipt of structured electronic invoices in domestic B2B and B2G transactions under Act No. 385/2025 Z.z.
• Later phases — cross-border coverage is expected to follow the EU VAT in the Digital Age timetable rather than the domestic date; the domestic system is designed in the first instance for invoice exchange within Slovakia.

Businesses Affected

The obligation from January 1, 2027 reaches Slovak VAT payers in domestic B2B and B2G transactions, which, under this design, means both the issuing and receiving sides. For multinational groups, the exposure sits in any Slovak company code and in any non-Slovak entity that issues invoices treated as domestic Slovak supplies—a population that is routinely underestimated because it does not correspond to the group's Slovak legal entity list.

The conference program is aimed principally at the domestic business population, including the very large number of sole traders and small businesses for whom structured invoicing is a genuine operational change rather than a systems project.

For a multinational, the program is nevertheless worth attending or monitoring for a specific reason: the authority's answers in the discussion segments are where transitional and borderline positions are first stated, often months before they appear in the FAQ.

Accounting and shared service providers serving Slovak entities are a third affected group, and one with concentrated risk: a provider that implements a single approach across its Slovak client base propagates any misreading of the regime across all of them.

Required Actions

• Download the current version of FAQ 9/DPH/2025/IM, record its date, and re-check for a new version monthly. Design decisions should cite the FAQ version they were taken against.
• Register a representative for at least one regional conference, or arrange for a Slovak adviser to attend, and capture the question-and-answer content rather than only the presentation material.
• Confirm that every Slovak-facing entity in the group holds the tax number required to be addressable under the mandate, taking account of the ex officio allocation reported by KGT on August 11, 2026.
• Establish the delivery route now rather than in the fourth quarter of 2026: identify the Peppol access point or delivery service, confirm the Slovak addressing arrangements, and test in the transition period while failure is not yet a compliance event.
• Map document types and scenarios against the FAQ: corrective documents, self-billing, advance invoices, summary invoices, non-VAT-payer counterparties, and supplies that are domestic Slovak supplies made by a non-Slovak entity.
• Use the remainder of 2026 as a live pilot. The transition period is the only window in which a Slovak structured invoice can fail without a compliance consequence.

Practical Implications

The first implication is one of interpretation risk. A decentralized mandate does not tell a taxpayer when it is wrong. A clearance platform rejects an invoice that does not conform; a Peppol-based model delivers it and leaves substantive correctness to be discovered later, on audit. That shifts the burden onto documented interpretation, and it makes the authority's published FAQ the most valuable compliance asset available for Slovakia.

The second is a timing implication. January 1, 2027 is a hard date, and the Slovak transition period is the only cost-free testing window. Organizations planning to build in the autumn of 2026 will test against a live obligation. Because Slovakia shares the January 1, 2027 date with Norway's B2B mandate, and sits close to Germany's 2027 issuance phase and Poland's final KSeF phase, market capacity in the last quarter of 2026 will be thinner than usual.

Third, the visibility of this program is itself informative. An authority that puts its president, its IT director general and its fraud prevention director general on a seven-city road show two quarters before a mandate is signaling both that it intends to hold the date and that enforcement design is already in place.

The fraud prevention directorate's presence on the speaker list is not decorative; it indicates that the reporting data flowing from the mandate is expected to be used analytically from the outset.

Expected Next Steps

A further reissue of FAQ 9/DPH/2025/IM should be expected during the autumn of 2026, and on recent cadence more than one. The Financial Administration is also likely to publish technical documentation and testing guidance for the delivery services in the run-up to January 1, 2027, and further outreach beyond the seven September events. Organizations should watch the Financial Administration eFaktúra section, the Ministry of Finance and the Slovak legal register slov-lex.sk for any implementing decree, and should treat any date change as unlikely on current evidence.

How Can KGT Support You?

KGT specializes in making statutory e-invoicing and digital reporting work inside SAP rather than alongside it. Our SAP-integrated e-invoicing add-ons cover clearance, network and reporting models, including Peppol-based exchange, and are designed so that a change in a validation artifact is absorbed as a configuration and mapping change rather than a project. Where a client runs SAP Document and Reporting Compliance (SAP DRC), KGT delivers implementation, extension and support services, including mapping to national customizations, eDocument and Statutory Reporting configuration, and the monitoring processes that turn a rejection into a resolved exception rather than an unbooked invoice.

For the readiness questions raised by this update, KGT can perform an impact assessment across the affected company codes, confirm which validation artifact version your access point or platform is running, test representative document flows against the current rules ahead of the enforcement date, and put a version-watch process in place so that the next release is picked up before it becomes mandatory rather than after the first rejection.
