The EU’s VAT in the Digital Age (ViDA) is often framed as an e-invoicing reform, but its real impact is the shift towards a real-time VAT data environment. As tax authorities adopt continuous transaction controls and combine transactional data with sources such as customs, point-of-sale systems, payroll and audit files, they are gaining unprecedented visibility into business operations.
At the same time, many administrations are moving toward pre-filled VAT returns, generated directly from the data businesses report. This changes the dynamic of compliance: organisations must ensure consistency across all reporting flows and be prepared to explain discrepancies rather than tax authorities discovering them during audits.

As indirect transaction tax becomes more complex and digitally enforced, organisations are increasingly challenged by limited visibility into the data that underpins compliance. Tax-relevant information is often fragmented across AP, AR, ERP, billing and e-invoicing systems, creating inconsistency and risk well before returns are filed. This webinar explores the business impact of disconnected transaction data, from errors in tax calculations and manual reconciliation to increased audit pressure and reduced confidence in reported figures. Our experts will outline what effective end-to-end transaction data control looks like and demonstrate how Sovos Intelligence unifies data, identifies risks in real time and enables proactive, automated compliance.

How Tax Compliance Is Changing in SAP
Tax compliance in SAP is no longer just an IT decision. It’s a strategic risk decision.
As governments shift to real-time, transaction-level enforcement, SAP customers are being forced to rethink how tax compliance fits into their S/4HANA, Clean Core, and data governance strategies.
Many organizations are evaluating ERP-native approaches, while others are expanding their capabilities to account for authority-led, end-to-end compliance models designed to keep pace with continuous mandates. Each path comes with tradeoffs in cost, risk, scalability, and long-term agility.
In this session, Sovos tax and SAP experts explore how SAP customers should think about this decision, not from a product perspective, but from an enterprise architecture, risk, and operating model standpoint.
You’ll learn:
-Why tax compliance is shifting from an internal ERP function to an externally enforced, authority-led model
-What SAP customers should consider when using ERP-native tools for digital reporting and mandates, and what capabilities to enhance and complement those tools
-The hidden complexity behind e-invoicing, SAF-T, and continuous transaction controls
-How Clean Core principles intersect with tax data, controls, and audit exposure
-Key questions IT, Finance, and Tax leaders should be asking before choosing a compliance path
-How today’s compliance decisions can impact transformation risk for years to come
This session is designed for IT and ERP leaders, Finance and Tax executives, SAP CoE and Clean Core program owners, and enterprise architects responsible for compliance strategy, and is especially relevant for organizations preparing for the 2026–2027 regulatory expansion or actively navigating an S/4HANA transformation.

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 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.
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.
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:
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.
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:
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.
According to the Polish legislation, the mandatory e-invoicing obligation through KSeF will apply to:
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.
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.
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.
Taxpayers have multiple options to receive their e-invoices from the KSeF platform:
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.
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:
Consumers can use these methods to access their invoices without the need to log into the 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.
Authentication can be done via:
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.
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.
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.
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.
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.
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.
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.
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. Attachments can only contain mandatory invoice elements specified in the Polish VAT Act or closely related data, while including marketing information and advertising content is prohibited.
To include attachments with invoices in KSeF 2.0, businesses must submit a notification via the e-Tax Office to the National Tax Administration before using this feature. The attachment functionality, available from January 1, 2026, is valid for 2 years after approval and requires renewal to continue.
Yes. From February 1, 2026, to December 31, 2026, financial penalties for KSeF-related violations will not be enforced. This transitional period allows businesses time to adapt without facing fines.
Sovos has created a number of resources to help businesses prepare for Poland’s KSEF 2.0 e-invoicing requirements:

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.
