Croatia E-invoicing
Croatia is implementing a comprehensive e-invoicing and fiscal reporting system under the Fiscalization 2.0 framework.
This system combines mandatory real-time reporting with e-invoicing for B2B and B2G transactions, aiming to prepare for and align with the requirements of ViDA. This integrated approach requires businesses to exchange electronic invoices and report fiscal data in real time to the Croatian Tax Administration.
This page provides an ideal overview of Croatia e-invoicing, covering the latest regulatory changes and compliance requirements.
Croatia’s e-invoicing mandate operates under the Fiscalization Law (Zakon o fiskalizaciji NN 89/25), which was published in June 2025 and entered into force on 1 September 2025.
This law establishes the “Fiscalization 2.0” framework, which introduces a decentralised mandatory e-invoicing model for domestic B2B and B2G transactions—alongside a continuous transaction control (CTC) real-time reporting system for B2B, B2G and B2C transactions.
Under Croatia’s Fiscalization 2.0 system, VAT-registered businesses must begin mandatory e-invoicing and CTC reporting from 1 January 2026.
Non-VAT registered businesses (small companies, freelancers, certain public bodies) that issue invoices must begin e-invoicing and CTC reporting from 1 January 2027.
CTC e-reporting in Croatia
Croatia implements a dual electronic reporting system:
CTC e-reporting (Fiscalization) requires real-time reporting of fiscally relevant data from outbound invoices and a 5-day reporting window for inbound invoices.
E-reporting of additional events (eReporting, Article 50 of Fiscalization Law) is an additional periodic or real-time reporting of invoice payment information, invoice rejections by the recipients, and transactions where invoices could not be issued because the buyer didn’t register its e-invoice address in the Central DNS-based directory (AMS).
Croatia’s CTC system
Croatia uses a decentralised e-invoice exchange model with CTC e-reporting.
Invoices must be issued electronically in a format that complies with the European Norm. They must be exchanged through Access Points or any other means agreed upon between the parties, e.g. compliant EDI, Peppol, provided they ensure authenticity of origin, content integrity, and readability from issuance until the end of the e-invoice retention period.
CTC reporting and e-invoicing may be outsourced to third-party service providers, referred to as “information intermediaries,” who are listed on the tax administration website.
B2G e-invoicing in Croatia
Since the end of 2018, public sector entities have been required to accept and process e-invoices from suppliers in public procurement. E-invoicing as a whole, i.e. also in the B2G flow, became mandatory in this sector on 1 July 2019.
B2G e-invoicing continues to operate under the existing Law on Electronic Invoicing in Public Procurement (NN 94/18), with FINA’s eRacun remaining the mandatory central platform for public sector transactions.
However, under Croatia’s Fiscalization 2.0 system, B2G transactions now have an additional compliance layer and are now subject to the e-invoice fiscalization process in the form of CTC e-reporting alongside the existing public procurement e-invoicing requirements.
Timeline of e-invoicing adoption in Croatia
Here are the key dates in Croatia’s journey towards mandating electronic invoicing.
1 December 2018: All contracting parties must accept and process e-invoices in public procurement
1 July 2019: E-invoicing becomes mandatory in public procurement
13 June 2025: Croatia approves Fiscalization law (NN 89/25), expanding the legal framework to include mandatory e-invoicing and CTC e-reporting
3 July 2025: Production system available for voluntary testing
1 September 2025: “Fiscalization 2.0” system becomes applicable; start of mandatory testing for technically ready entities
1 January 2026: Mandatory e-invoicing (issuance and receipt) and e-reporting begin for VAT-registered businesses, as part of “Fiscalization 2.0”; mandatory e-invoicing (receipt) begins for non-VAT-registered businesses
1 January 2027: Mandatory e-invoicing (issuance) and e-reporting begin for non-VAT-registered companies, as part of “Fiscalization 2.0”
1 July 2030: Croatian VAT-registered businesses must comply with VAT in the Digital Age (ViDA) requirements, which include mandatory e-invoicing and digital reporting for Intra-Community B2B transactions
Setting up e-invoicing in Croatia with Sovos
Tax and e-invoicing compliance can be particularly time-consuming and complicated when you operate in numerous countries, considering that rules and regulations change often. Having a single partner for compliance wherever you do business saves you time and provides peace of mind.
Sovos can be that partner for you. Get in touch to find out more.
E-invoicing with CTC reporting becomes mandatory for VAT-registered businesses and non-VAT-registered businesses that receive e-invoices on 1 January 2026, and for non-VAT-registered businesses that issue e-invoices from 1 January 2027 under the Fiscalization 2.0 framework.
Fiscalization 2.0 is Croatia’s comprehensive digital tax system, combining mandatory e-invoicing with Continuous Transaction Controls (CTC). It requires real-time reporting of fiscal data from both issued and received invoices, plus additional e-reporting of events like payments and rejections. The system aims to digitise tax compliance, increase transparency, and reduce administrative burdens.
Croatia implements a combined CTC e-reporting and decentralised e-invoicing system requiring real-time fiscal reporting to tax authorities and exchange of e-invoices via certified service providers. This corner-5 model is similar to other countries that have implemented or are in the process of implementing this CTC model, such as France, Greece and Slovakia and aims to align with ViDA.
Croatia’s system uses components with similar functions to Peppol (Access Points, metadata services, AS4 protocol), however, it operates under its own certification processes and requirements. The Peppol network may be used as an alternative method of exchanging e-invoices, provided that it ensures the integrity and authenticity of the e-invoice.
The Croatian mandate through its Fiscalization 2.0 system directly implements ViDA’s central concept of digital real-time reporting based on e-invoicing. Starting with a national application of a real-time transaction-based e-reporting system, the country is building infrastructure that sets the foundation for the transition to a new reporting system for intra-EU trade in the digital age.
While Liechtenstein has not introduced any mandates for electronic invoicing in the country, there are rules to be followed for voluntary e-invoicing.
Liechtenstein is earlier in its journey towards mandatory e-invoicing than many countries. There are no mandates, no official platforms and no national standards.
The only e-invoicing rule pertains to the public authorities’ requirement to receive and process EN 16931-compliant electronic invoices for public procurement contracts exceeding a specific value threshold.
This page provides an ideal overview of Liechtenstein E-invoicing. Bookmark it to stay ahead of regulatory changes.
There is no mandate in Liechtenstein for using electronic invoices regarding business-to-business (B2B) transactions.
A supplier must obtain explicit consent from a buyer before voluntarily issuing an e-invoicing for a B2B transaction. E-invoices must meet the EN 16931 European Standard. If they choose to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin by using, for example, an electronic signature.
B2G e-invoicing in Liechtenstein
In November 2017, the government introduced the Public Procurement Act. This law establishes a legal framework for the use of electronic invoices in public procurement. While no mandate was introduced, the Act laid a foundation for the country’s approach to e-invoicing.
However, the law introduced the requirement for public authorities to receive and process e-invoices that meet the European Standard on e-invoicing (EN 16931). This rule comes into effect when “public authorities pay suppliers for goods or services provided through formal procurement contracts above the thresholds provided in the Public Procurement Directives,” as per the European Commission.

Here are the milestones in Liechtenstein’s e-invoicing journey.
10 November 2017: The Public Procurement Act establishes a legal framework for e-invoicing in public procurement—laying the foundation for a potential future mandate
June 2020: the Liechtenstein E-invoicing Forum (LEIF) stops playing its observer role in the European Multi-Stakeholder Forum on Electronic Invoicing (EMSFEI)
January 2025: Businesses must use the new electronic VAT portal for all VAT-related transactions
Setting up e-invoicing in Liechtenstein with Sovos
While Liechtenstein currently has only one specific use case for e-invoicing, it may follow other countries in introducing mandates in the near future. You must be agile and meet your regulatory requirements everywhere you do business—and that includes electronic invoicing.
Many countries now require businesses to issue e-invoices for both B2B and B2G transactions. Is your organisation set up to meet these demands?
With Sovos, you have a single compliance partner for all your tax compliance needs, helping you now and in the future as rules and requirements evolve. Free up time and headspace by contacting us today.
No, there is no mandate for B2G or B2G e-invoicing in Liechtenstein. The only rule governing electronic invoicing in the country pertains to public procurement, where public authorities must be able to receive and process European Standard-compliant e-invoices for contracts exceeding a specific value threshold.
The Ministry of General Government Affairs and Finance is the specific governmental department that is responsible for overseeing and implementing e-invoicing regulations in Liechtenstein. That said, it has not yet introduced any electronic invoicing mandates, platforms or standards.
E-invoices sent in public procurement must comply with the European Standard (EN 16931), but Liechtenstein’s Ministry of Finance has designated no specific format for these documents.
E-invoices for public contracts must be sent to the Liechtenstein national administration in XML format.
Cyrille Sautereau – President FNFE-MPE & CEO Admarel Conseil
Ahead of the Tax Compliance Summit Sovos Always On: Paris on 19th November, we asked Cyrille Sautereau, Chair of the AFNOR “Electronic Invoice” Commission and President of the National Forum for Electronic Invoicing and Public eProcurement (FNFE-MPE), to discuss the evolving landscape of e-invoicing reform in France, the challenges of interoperability, and the country’s role in shaping European standards.
The National Forum for Electronic Invoicing and Public eProcurement (FNFE-MPE) plays a key role in coordinating discussions around the reform. Could you remind us of the Forum’s mission and how it serves as a bridge between the administration and businesses?
The National Forum for Electronic Invoicing was created in 2012 following the establishment of the European Multi-Stakeholder Forum on Electronic Invoicing (EMSFEI), which led several Member States, including France and Germany, to create their own mirror forums. From the outset, its mission has been to support the development of e-invoicing in France, across both public and private sectors, in alignment with EU initiatives. We became an association in 2016 and now have more than 280 members divided into three colleges: users, service providers, and independent experts and consultants.
Our role is both normative and educational. Normative, because we actively contribute to the development of European and national e-invoicing standards, in close collaboration with the AFNOR “Electronic Invoice” Commission, which I also chair; and educational, because we provide best practices and help the ecosystem understand the regulations, enabling companies to transition smoothly to e-invoicing.
Finally, we fully play our role as a bridge between public authorities and the market. The FNFE is regularly consulted by the tax administration and lawmakers, particularly on regulatory developments related to the reform. We bring field expertise — our knowledge of invoicing practices, tools, and the operational constraints businesses face. This ongoing dialogue helps fine-tune regulations and ensures a harmonized, effective implementation of the reform.
The FNFE-MPE brings together public institutions, businesses, software providers, and technical experts. How do you manage to unite these actors, whose interests sometimes differ, around common standards?
The FNFE-MPE brings together a wide range of stakeholders: businesses, vendors, service providers, accountants, professional federations, and even representatives of the public administration. Our mission is to facilitate dialogue among these groups, which don’t always share the same priorities. The key is transparency and co-construction: everyone can take part in our working groups and contribute to developing the standards.
We hold several plenary sessions each year, along with about ten thematic working groups covering topics such as e-invoicing reform, interoperability, standards and norms, communication, best practices, invoicing and payment, B2G invoicing, and factoring. These forums allow members to share feedback, identify practical challenges, and bring them to standardization bodies.
This collaborative approach has fostered a genuine common language between public and private actors. That’s the strength of the FNFE — its ability to unite the entire ecosystem around a shared vision, ensuring that both technical and regulatory choices remain realistic, effective, and business-oriented.
One of the major challenges of the reform lies in ensuring interoperability between private platforms and public systems. In your view, what are the main hurdles to overcome to ensure a smooth and coherent ecosystem?
Interoperability is indeed one of the most sensitive aspects of the reform. Contrary to what people might think, the main challenge doesn’t lie in connecting private platforms to the Public Invoicing Portal — that interface is precisely defined by the DGFiP’s specifications — but rather in ensuring smooth communication among private players themselves.
The first challenge concerns certified platforms (formerly PDPs), which must be able to exchange data without multiplying bilateral integrations. That’s why we supported the rollout of the Peppol network in France — a model where one connection makes you interoperable with all other network participants. The second pillar is a shared addressing system based on the SIREN number and managed within a public directory. This ensures that every business is reachable through a stable e-invoicing address — one that remains unchanged when switching platforms.
Finally, there’s the “last mile”: connecting companies’ internal systems (so-called “compatible solutions”) to their certified platforms. Given the variety of software tools on the market, proprietary integrations must be avoided. That’s the goal of the AFNOR initiative to design a standardized API — a universal connector that ensures seamless transitions between platforms. Portability is essential for an open, sustainable ecosystem.
The French e-invoicing mandate — the progressive obligation for all companies to issue and receive invoices through certified platforms starting in 2026 — is part of a broader European movement driven by the ViDA (VAT in the Digital Age) initiative. How does France position itself in this EU-wide transformation?
The French reform is closely aligned with the European ViDA project, which aims to harmonize e-invoicing and reporting practices across the EU. ViDA calls on Member States to establish systems for e-reporting and e-invoicing based on structured data and standardized formats — exactly what France has already implemented.
Our national model, based on the exchange of structured electronic invoices between French taxpayers and the automatic transmission of data to the tax administration, already mirrors ViDA’s intended architecture. The key difference is that France chose from the outset to combine mandatory e-invoicing with e-reporting to the tax authorities — whereas other countries limited their first phase to B2B e-invoicing, postponing e-reporting to a later stage. We also introduced two unique features: invoice status tracking — ensuring lifecycle traceability and giving suppliers the visibility and value they’re entitled to — and B2C e-reporting, which isn’t covered by the European scope. In short, France won’t need to adapt its system to ViDA; it already embodies it.
Some believe that France could become a reference model in Europe, provided it successfully deploys the reform. Do you share that view? What lessons could other Member States draw from the French approach?
France can indeed become a European benchmark, provided the operational rollout succeeds. What sets us apart is the decision to tackle the issue holistically, integrating technical, regulatory, and business aspects from the beginning. While other countries proceeded step by step — first e-invoicing, then reporting — we decided to merge both dimensions right away.
Requiring VAT data to be transmitted to the tax administration from each invoice inherently assumes that, within each invoice, the seller is responsible for VAT collection and the buyer for deduction. This creates additional complexity in many cases where intermediaries — such as aggregators handling invoice consolidation or grouped payments — play a role without being the actual taxpayer.
Our approach builds on significant collaborative work within the AFNOR “Electronic Invoice” Commission, which I also chair. Over six months, more than 250 experts from all sectors took part in over sixty meetings. This work revealed the real complexity of use cases, often underestimated — for example, scenarios where several service providers appear on a single invoice for one buyer, such as in the water, leasing, insurance, or travel sectors. These configurations turned out to be far more common than expected. The AFNOR work also helped align French practices with the European semantic standard EN 16931 — ViDA’s foundation — while identifying its limitations and addressing them through data extensions or management rule updates.
Finally, this process confirmed the need for flexibility — allowing human-readable formats, like hybrid Factur-X invoices, which include operationally useful data that may not fit within the semantic standard or technical capabilities of some small businesses.
This ability to identify specific cases and address them within a shared normative framework is, in my view, France’s main strength. It helps anticipate complex situations, deliver standardized solutions (“the same problems, the same answers”), and maintain coherence between regulatory requirements and business realities. Many Member States will likely draw inspiration from this integrated approach when implementing ViDA.
Beyond compliance, the reform will generate an unprecedented volume of standardized economic data. Do you think this infrastructure could ultimately become a driver of competitiveness and innovation for French companies?
Beyond compliance, the reform will fundamentally change how companies manage their operations. By generalizing e-invoicing, we’re introducing structured, reliable, and continuously available data — replacing the paper and PDF-based exchanges that still dominate today. This is transformative: data becomes instantly usable by management systems, without re-entry or manual processing.
In practical terms, this will allow all companies — including SMEs — to reach levels of automation and visibility previously reserved for large groups. Cash-flow reporting or monthly closings will no longer take days of reconciliation: invoices will be integrated in real time, and discrepancies will appear immediately. This responsiveness will enhance business leaders’ ability to manage performance, detect weak signals, and anticipate payment delays — in short, to shift toward predictive management.
In the long run, value-added services could emerge from aggregated, anonymized data analysis. For example, a platform could offer buyers average market price benchmarks based on peer transactions, helping them better position themselves competitively. These uses will need to be regulated to preserve confidentiality, but they open promising perspectives. Competitiveness will thus depend not only on compliance, but on data quality and intelligent exploitation.
You’ll be speaking at Sovos’ Always-On event on November 19, which will bring together public authorities, businesses, and solution providers around e-invoicing and tax compliance. What do you expect from such a gathering at this pivotal stage of the reform?
We regularly take part in events like Always-On because they play an essential role in collective education around the reform. The more opportunities for dialogue, the better. For the FNFE-MPE, it’s a concrete way to fulfill our mission of supporting businesses. These meetings help clarify what the reform truly entails, demystify its implementation, and provide a neutral perspective that complements that of service providers.
That’s important, because many companies still have a fragmented understanding of the reform: some overestimate its complexity, while others haven’t yet grasped its full impact. In this context, direct exchanges among public authorities, experts, vendors, and users are key to building a shared culture and reliable reference points. Such events help reinforce a crucial message: the success of e-invoicing depends on adopting shared standards, ensuring consistency of practices, and rejecting unnecessary complexity.
For too long, everyone built their own processes, portals, and formats — often with limited success. One of the reform’s main goals, and one of the benefits of events like Always-On, is to move beyond this “each to their own” mindset and build a truly interoperable ecosystem.
Among the many topics that will be discussed during the event, artificial intelligence stands out as particularly important. AI is now increasingly present in both compliance and tax controls. How can we ensure that this technological evolution strengthens — rather than undermines — the relationship of trust between taxpayers and authorities?
The importance of AI will grow as data volumes increase. AI can first help companies better understand what the administration “sees” about them by comparing their internal data with prefilled information. This “mirror visibility” can help identify and explain discrepancies even before an audit is initiated.
That said, we must remain clear-eyed about technology’s limits. AI is an analytical support tool, not an arbiter of truth. Its effectiveness will always depend on the algorithms behind it and the quality of the data it processes. Used rigorously and transparently, AI can strengthen trust between companies and tax authorities by making processes more objective and efficient. Conversely, if poorly managed, it risks creating new areas of opacity or misunderstanding.
The challenge in the years ahead will be to strike the right balance: leveraging AI’s power to make compliance more reliable and streamlined while preserving human interpretation and dialogue. Only under these conditions can technology truly serve trust, rather than weaken it.
KSeF, or the National E-Invoicing System, is Poland’s approach to continuous transaction controls (CTC), a trend that sees tax authorities gaining real-time visibility of transactions. The ‘clearance’ model implemented in Poland demands that invoices be issued in a structured electronic format and undergo validity checks, ensuring compliance and accuracy of e-invoices before they are sent to recipients.
Operational on a voluntary basis since 2022, the KSeF e-invoicing system is set to become mandatory in phases starting February 2026. Poland’s e-invoicing requirements encompass both VAT active and exempt entities, covering B2B and B2G transactions, while B2C e-invoicing remains optional. Importantly, the system includes both domestic and cross-border transactions, although with specific rules for invoice exchange in cross-border scenarios.
KSeF 2.0: key changes and features
KSeF 2.0 emerged as a direct response to stakeholder feedback during the voluntary implementation phase. After extensive public consultations, the Polish Ministry of Finance addressed several critical concerns raised by businesses. These included the need for offline invoicing capabilities during connectivity issues, support for B2C transactions, clearer rules for self-billing in cross-border scenarios, better handling of complex business structures like VAT groups, and many other concerns.
The resulting KSeF 2.0 framework includes both legislative changes (through the KSeF 2.0 Act and other implementing regulations) and technical enhancements (via the new FA3 schema and API). The new system adds support for optional B2C invoicing, previously unavailable in the voluntary phase, giving issuers the discretion to include such transactions within KSeF. It also introduces the KSeF certificates, which will be used for authentication in the system and for the generation of the QR code used in the offline modes. Special attention is given to offline modes, particularly the “offline 24” mode, which allows for invoice submission by the next business day in case of issues on the taxpayer’s side.
Key functionalities and adjustments included in KSEF 2.0
B2C e-invoicing: Businesses can optionally issue B2C e-invoices via KSeF, with no consumer consent required, although consumers must request an invoice. If the issuer chooses to issue via KSeF, consumers retain the right to request receiving an alternative invoice format outside of KSeF.
Offline modes: Four distinct offline scenarios are supported:
“Offline24” for connectivity issues on the taxpayer side
Standard “Offline Mode” for planned system maintenance
“Failure Mode” for unexpected system errors on the tax authority’s side
“Total Failure Mode” for extraordinary situations threatening country infrastructure
QR codes: Two types of QR codes are introduced to ensure invoice authenticity and access, crucial for invoices exchanged outside KSeF:
Access QR code provides verification in KSeF
Certificate QR code ensures invoice integrity and authenticity
QR codes will be required when exchanging invoices outside of KSeF both in online or offline modes with the need to add a second QR code for invoices issued in offline mode and sent to the recipient before KSeF clearance.
Postponements: Until 31 December 2026, several requirements are postponed, including financial penalties for KSeF-related errors and violations, the obligation to include KSeF numbers in payments, and the ability to continue issuing cash register invoices outside KSeF.
FA3 schema enhancements: The new logical structure introduces expanded fields for VAT groups, government units, employee expenses, and a new optional attachment element, which allows for structured XML attachments for complex invoices with detailed item data, subject to prior registration with the tax authority.
The timeline to KSeF implementation
The timeline for KSeF implementation is marked by key milestones set by the Polish Ministry of Finance:
June 2025: the FA3 schema and API documentation were published, marking a significant step towards KSeF 2.0’s rollout.
September 2025: testing of the new system will commence, with the ability to download internal certificates starting in November of this same year.
February 2026: the mandatory shift to KSeF 2.0 will begin for large taxpayers, defined as those with sales exceeding 200 million PLN (approx. €46 million) in 2024
April 2026: KSEF becomes mandatory to all other taxpayers.
Importantly, businesses with monthly sales up to 10,000 PLN ( €2,300) will be granted a transitional exemption until January 2027.
What’s next for Poland e-invoicing requirments?
As Poland advances towards the full implementation of KSeF 2.0, businesses must stay informed and prepared for these regulatory changes. The system’s phased rollout offers a window for adaptation, but early compliance will ensure smoother transitions and mitigate potential disruptions.
Sovos has created a number of resources to help businesses prepare for Poland’s KSEF 2.0 e-invoicing requirements:
KSEF 2.0 FAQ document – a detailed resource addressing common queries to help support your journey with KSEF 2.0
Poland e-invoicing tax rules – the main webpage to stay up to date with current and upcoming e-invoicing regulations in Poland
KSEF timeline – a comprehensive timeline of Poland’s e-invoicing mandate, updated with the latest announcements from the tax authority
Sovos’ team of regulatory tax experts answer some of the most frequently asked questions about KSEF 2.0, an upcoming update to Poland’s national electronic invoicing system.
1. What are the main changes in KSeF 2.0?
KSeF 2.0 introduces several important features not available in the 1.0 system in use during the voluntary period. The most significant changes include:
Optional B2C e-invoicing
The permanent Offline24 Mode allowing businesses to issue invoices outside the system and submit them to KSeF by the next working day
Mandatory QR code for invoices issued in offline modes
mandatory use of the updated FA(3) logical structure format
Postponement of deadlines for certain KSeF-related obligations
2. What is the implementation timeline for KSeF 2.0?
The KSeF 2.0 implementation begins with open testing from September 30, 2025, followed by KSeF certificates availability on November 1, 2025. As confirmed by the KSeF 2.0 Act, mandatory structured e-invoicing starts February 1, 2026 for taxpayers with sales exceeding 200 million PLN in 2024, and April 1, 2026 for all other taxpayers.
An exemption allows taxpayers with monthly sales below 10,000 PLN to continue issuing paper or electronic invoices until December 31, 2026.
3. Which entities are obligated to use KSeF?
According to the Polish legislation, the mandatory e-invoicing obligation through KSeF will apply to:
Taxpayers with a registered office in Poland
Taxpayers with a permanent place of business in Poland that is involved in the delivery of goods or provision of services for which the invoice is issued
4. Does sole VAT registration in Poland mean a company is subject to KSeF?
Polish legislation states that the taxpayer must have either a registered office or a permanent establishment in Poland that participates in the transaction to fall under mandatory KSeF. VAT registration alone does not trigger the obligation.
5. What documents are included in KSeF and what are excluded?
Not all document types fall within the scope of the KSeF system. The system supports VAT invoices, corrective invoices, self-billing invoices, and VAT RR invoices (optional from April 2026). However, several documents are excluded from KSeF, including internal invoices, pro forma invoices, and traditional debit/credit notes.
6. Are cross-border transactions included in the KSeF mandate?
Yes, Polish businesses must submit e-invoices to KSeF for sales to foreign customers. After submission, the Polish supplier must provide the invoice to the foreign customer in an agreed format, including a QR code for KSeF access. This applies to all cross-border sales by Polish taxpayers under KSeF.
7. How can taxpayers access invoices from the KSeF system?
Taxpayers have multiple options to receive their e-invoices from the KSeF platform:
Direct integration with the tax authority by connecting to the KSeF’s API
Through a third-party service provider who can retrieve e-invoices on their behalf
Manually downloading e-invoices via the KSeF portal
8. How does KSeF 2.0 handle B2C transactions compared to KSeF 1.0?
Unlike KSeF 1.0, which did not support B2C e-invoicing, KSeF 2.0 allows voluntary B2C e-invoicing. Consumers must still request an invoice before one can be issued, but the issuer decides whether to fulfill this request via KSeF or through traditional methods without requiring consumer consent.
9. How will consumers access their invoices in KSeF?
The KSeF 2.0 legislation establishes an “anonymous access” mechanism for consumers. When sellers issue e-invoices to consumers through KSeF, they must provide one of the following:
A verification code for the invoice in the system and data that enables identification of the invoice
A QR code that enables access to the e-invoice in KSeF
Consumers can use these methods to access their invoices without the need to log into the system.
10. How do credit and debit notes work in the KSeF system?
Traditional credit and debit notes as separate document types (commonly used in many countries) won’t be part of the KSeF system. Instead, all corrections must be made through a “corrective invoice” document type that KSeF supports. Additionally, correction notes issued by buyers in Poland will also remain outside KSeF’s scope.
11. What certificates or access credentials are needed to issue in KSeF 2.0?
Authentication can be done via:
Electronic identification linked to the national node
Qualified electronic signature or seal
KSeF certificate obtained after initial authentication by one of the first three methods.
The Trusted Profile method will be eliminated from 1 April 2026. KSeF Certificates will be available for download from November 1, 2025 via the Certificates and Authorizations Module (MCU), which will be made available in the KSeF domain.
12. What offline modes are available in KSeF 2.0?
KSeF 2.0 offers four offline modes. Offline24 mode is designed for issues on the taxpayer’s side, such as connectivity problems and internet outages. Offline mode is for planned system maintenance periods when KSeF is temporarily unavailable. Failure mode is for unplanned system failures that are officially announced in the bulletin of the Ministry of Finance. Total failure mode is for extraordinary situations like threats to the country’s infrastructure, announced through media channels.
13. What is the Offline24 mode in KSeF 2.0 and how does it work?
Offline24 mode is a solution created to address concerns about potential delays in invoice submission due to issues on the taxpayer’s side. It allows businesses to issue structured invoices outside the system, and to submit them to KSeF no later than the next business day following the FA(3) format.
14. How do recipients receive invoices issued in Offline24 mode in KSeF 2.0?
Domestic business recipients with a NIP receive invoices exclusively through the KSeF system after their submission and clearance. Other recipients (consumers, foreign entities, or entities without a NIP) receive invoices in a manner agreed with the buyer outside of KSeF, with one or two QR codes.
15. What are the QR code requirements for invoices in KSeF 2.0?
When an invoice is sent to the recipient outside KSeF, it must include one or two QR codes. There are two types of QR codes: one for accessing the invoice and another for ensuring integrity and authenticity. If the invoice is provided to the recipient after KSeF clearance, only the access QR code is required. When providing the invoice to the recipient before KSeF clearance, the two QR codes are needed.
16. Is a QR code required on non-domestic invoices?
Access QR codes are mandatory on all invoices exchanged outside the KSeF system, including cross-border transactions. Polish companies must first submit the e-invoice to KSeF, then provide it to foreign partners in any agreed format along with a QR code. This allows foreign recipients to verify the invoice’s authenticity and access it in the Polish tax authority’s system when needed.
17. What invoice format will be used in KSeF 2.0?
From February 1, 2026, KSeF 2.0 will exclusively use the FA(3) logical structure for all structured invoices. The FA(3) schema includes enhanced features like support for attachments, inclusion of new fields and other updates to code formats, schema variants, and data types.
18. What are invoice attachments in KSeF 2.0 and what can they contain?
Invoice attachments in KSeF 2.0 are an integral part of structured invoices designed specifically for entities who need to include complex detailed data in their invoices.

The IRS has confirmed the retirement of the long-standing FIRE system, ushering in a new era of information return filing through IRIS. After serving as the backbone of electronic tax reporting since the 1980s, this significant change will reshape how organizations approach information return filing.
Join Sovos tax experts for a deep dive into what this transition means for your business. We’ll break down the timeline, requirements, and risks while offering practical guidance to ensure a smooth move to IRIS.
Most finance and tax teams think they’ve got sales and use tax under control. Auditors know better.
In this webinar, we expose the hidden audit risk that’s catching even the most sophisticated companies off guard: use tax.
While sales tax automation gets all the attention, use tax compliance remains a patchwork of spreadsheets, siloed systems, and unvalidated assumptions – a goldmine for state auditors on the hunt for revenue.
The “One Big Beautiful Bill” (OBBB) represents one of the most sweeping shifts to the tax compliance landscape in recent history. With wide-ranging provisions that touch nearly every corner of information reporting and withholding (IRW), this legislation will fundamentally reshape how organizations manage compliance, reporting, and operational risk.
For tax leaders, the OBBB is more than just new rules—it’s a call to rethink long-standing processes and prepare for a transformed regulatory environment.
Slovenia E-invoicing
Slovenia is in the middle of its journey towards mandatory e-invoicing. It is already in place for B2G transactions, and the current plan is for B2B e-invoicing to be compulsory from 2027.
Learn more about Slovenia E-invoicing through this page, and be sure to bookmark it to keep up to date with future regulatory updates.
While there is no mandate for B2B e-invoicing, Slovenia’s tax authorities plan to introduce an obligation.
Currently, the plan is for e-invoicing for business-to-business transactions to become obligatory from 1 January 2027.
Should the obligation come into effect, businesses will need to be able to issue, receive and process e-invoices for transactions with other organisations. However, e-invoices cannot be sent via email.
This obligation will cover cross-border transactions, requiring businesses to issue e-invoices for exports and imports.
The plan is for e-invoices to be acceptable in the following formats:

EN 16931 EU standard
Internationally recognised formats agreed by both parties
The regulation will require issuers and recipients to forward e-invoices, in the e-SLOG format, to the tax authorities within eight days of issuance.

Slovenia has a national e-invoicing format, e-SLOG, which was updated to align with the European e-invoicing standard EN 16931.
There is a national registry of electronic invoicing recipients to provide transparency into exchanges, and the PPA incorporates eDelivery standards to ensure interoperability with European networks.
