E-Invoicing in Europe 2026-2030: How It Is Being Implemented Country by Country
Europe is experiencing the largest transformation of business invoicing in decades. What five years ago seemed like a distant trend — the obligation to issue structured electronic invoices between businesses — is already a reality in several countries and will be mandatory across the EU for intra-Community transactions by 2030. Each country is moving at its own pace with different technical models, but the direction is the same: machine-readable invoices, real-time data for tax authorities and the end of paper and PDF as valid invoice formats.
ViDA: the European framework that changes everything
On 11 March 2025 the EU Council formally adopted the ViDA (VAT in the Digital Age) package, the most ambitious reform of the European VAT system since its creation. Published in the Official Journal on 25 March 2025, ViDA sets out a progressive timeline culminating in 2035:
- April 2025: Member States can now impose mandatory e-invoicing for domestic transactions without prior authorisation from the European Commission.
- January 2027: updates to the e-commerce package and extension of the OSS (One-Stop Shop) system.
- July 2028: new obligations for digital platforms (accommodation and transport) as "deemed suppliers", with a possible national postponement to January 2030.
- July 2030: mandatory e-invoicing in EN 16931 format for all intra-Community B2B and B2G transactions, together with real-time Digital Reporting Requirements (DRR).
- January 2035: countries that already had domestic digital reporting systems before 2024 (such as Italy, France or Spain) must align them with the ViDA standard.
ViDA's message is clear: the structured electronic invoice will become Europe's single standard. PDFs, paper invoices and unstructured formats will no longer be valid for intra-Community transactions.
The three technical models in Europe
Not all countries implement e-invoicing the same way. There are three broad models:
Clearance model: the invoice passes through a centralised tax authority system that validates it before it becomes legally valid. Italy pioneered this with the Sistema di Interscambio (SdI) in 2019. Poland has followed with KSeF. Spain's VeriFactu in submission mode comes close to this model.
Exchange model (Peppol/networks): invoices are exchanged between businesses through certified networks such as Peppol, without necessarily passing through a central fiscal validator. Belgium and the Nordic countries use this approach. Invoices are reported to the tax authority in parallel or afterwards.
Post-audit model: invoices are freely issued and the tax authority reviews them later, typically through SAF-T files or periodic reporting. Germany and several Eastern European countries are transitioning from this model towards more active ones.
In practice, many countries combine elements of several models. France, for example, uses certified platforms (PDP) in a "five-corner" model that blends private exchange with centralised reporting.
Country by country: who requires what and when
Italy — the pioneer
Italy was the first EU country to mandate B2B e-invoicing, in January 2019. All domestic invoices (B2B, B2C and B2G) must be issued in FatturaPA format (a proprietary XML schema) and transmitted through the Sistema di Interscambio (SdI), which acts as a centralised validation platform. Any other format must be converted to FatturaPA before submission. It is Europe's most mature clearance model.
Poland — KSeF under way
Poland has launched its KSeF (Krajowy System e-Faktur) system in phases: from February 2026 for large taxpayers (turnover >PLN 200M) and from April 2026 for all others. It uses the FA(3) XML format, a proprietary schema, and a centralised clearance model where every invoice must pass through KSeF and receive an identifier before being sent to the customer. The legal invoice is always the XML; the PDF is merely a visualisation.
Belgium — mandatory Peppol
Since 1 January 2026 all Belgian VAT-registered businesses must exchange B2B invoices in structured format via the Peppol network using Peppol BIS (UBL 2.1) format. It is the first EU country to make Peppol mandatory for B2B — a decentralised approach without a central fiscal platform.
France — phased rollout from September 2026
France begins its rollout in September 2026. All businesses must be able to receive e-invoices. Large and medium-sized companies must also issue them. SMEs and micro-businesses will join in September 2027. The model uses certified private platforms (PDP) connected to a public central platform (PPF) acting as a directory and data concentrator. It accepts three formats: UBL, CII and Factur-X (a Franco-German hybrid format).
Germany — mandatory receipt, issuance in 2027-2028
Germany has required the ability to receive e-invoices since January 2025. The obligation to issue them will come in stages: January 2027 for companies with turnover above €800,000 and January 2028 for all others. No single format is mandated — any format compliant with the EN 16931 standard is accepted (the most common being XRechnung and ZUGFeRD). Germany's approach is pragmatic, with extended transition periods.
Spain — VeriFactu and B2B e-invoicing
Spain is implementing two parallel regulations. On one hand, VeriFactu (RD 1007/2023), which governs the technical requirements of invoicing software (hash, chaining, QR, optional submission to AEAT) with a deadline of January 2027 for corporations and July 2027 for freelancers. On the other, mandatory B2B e-invoicing (Law 18/2022, Crea y Crece), developed by RD 238/2026, which sets the following dates:
- 1 October 2027: mandatory for companies with turnover exceeding €8,000,000.
- 1 October 2028: mandatory for all other businesses and professionals.
The public e-invoicing solution will be available on the AEAT's electronic portal at least 2 months before the first application date.
What makes Spain distinctive is that VeriFactu offers two modes (VeriFactu and No-VeriFactu), and it is the taxpayer who chooses — a flexibility rarely found in the European landscape.
In addition, the Resolution of 18 December 2024 (BOE-A-2024-27600) approved standardised representation documents for submitting VeriFactu records through third parties. This defines how software companies and tax professionals (accountants, advisers) can act as representatives of the taxpayer before the AEAT, establishing three models: direct representation from taxpayer to software provider (Annex I), from taxpayer to tax professional (Annex II), and from tax professional to software provider (Annex III). It is a key piece of infrastructure that enables accountancy firms and SaaS platforms to submit records on behalf of their clients.
Portugal — CIUS-PT and Peppol in 2027
Portugal already requires structured format (CIUS-PT) for B2G and QR codes on B2B invoices. Mandatory B2B e-invoicing is planned for January 2027 via the Peppol network.
Romania — RO e-Factura active
Romania has its RO e-Factura system active with B2B mandates since 2024, expanding to simplified B2C invoices in 2025. It is another clearance model where invoices pass through a centralised validation system.
Nordic countries — Peppol well established
Sweden, Norway, Denmark and Finland have been using Peppol for B2G for years and have mature infrastructure. Denmark will require digital accounting systems compatible with e-invoicing and SAF-T from January 2026. Norway plans mandatory B2B e-invoicing in 2027 and digital bookkeeping by 2030.
Greece — tax incentives for early adoption
Greece has an active electronic tax reporting system and offers financial incentives to businesses that adopt e-invoicing early: 100% additional depreciation on technology and 100% increase in deductible expenses for creating and managing e-invoices.

What all these systems have in common
Despite the differences, several elements recur across all countries:
Paper and PDF are disappearing as legal formats. In all advanced models the legally valid invoice is the structured XML file. The PDF, if it exists, is merely a visual representation. A mismatch between XML and PDF can entail serious fiscal risks (as seen in Poland with KSeF).
The EN 16931 standard is emerging as the common foundation. It is the European reference standard for electronic invoices, revised in 2025 for B2B transactions. Each country may add its CIUS (national usage specification), but the core is the same.
The trend is towards real-time reporting. Whether through clearance (Italy, Poland), voluntary submission (Spain with VeriFactu) or parallel reporting (France), the direction is for tax authorities to have access to invoicing data almost at the moment of issuance.
Penalties for non-compliance are significant everywhere. From €50,000 per fiscal year in Spain to proportional fines based on turnover in other countries.
What is not said: credit seizures and the revenue use of invoice data
There is an aspect of real-time e-invoicing that rarely appears in official guides but has a direct impact on business operations: the use of invoicing data to accelerate credit seizures.
When a tax authority has real-time access to all invoices issued by a taxpayer, it can not only verify VAT compliance — it can also quickly identify which customers owe money to the taxpayer and act on those receivables if the taxpayer has outstanding tax debts.
Italy has already formalised this. The Manovra 2026 (Italian Budget Law) expressly authorises the Agenzia delle Entrate-Riscossione to use e-invoice data from the Sistema di Interscambio (SdI) to locate receivables from customers and initiate faster, more targeted pignoramenti (seizures). The stated goal is to collect over €1 billion in additional annual revenue. Of roughly 600,000 third-party seizures executed each year in Italy, only 22.5% succeed; with e-fatture data, the tax authorities expect to significantly improve that success rate by identifying the right third party — the customer where an interceptable receivable exists.
Spain has the same capability. With VeriFactu in submission mode, the AEAT receives invoicing records in real time and can cross-reference data to issue credit seizure notifications on recently registered invoices if the issuer has outstanding debts. This is precisely one of the reasons why RD 1007/2023 offers No-VeriFactu as an alternative: the taxpayer who does not send records in real time does not expose that information until they file Form 347 in February of the following fiscal year, or until the AEAT formally requests it in an inspection.
Poland (KSeF) grants the tax authority (KAS) real-time access to all invoicing data. Although the explicit use for credit seizures has not been regulated as openly as in Italy, the technical capability is there: KAS can see every invoice issued and received by any taxpayer the moment it is issued.
Belgium, Germany and the Nordic countries operate with exchange (Peppol) or post-audit models where the tax authority does not have immediate access to invoicing data on a transaction-by-transaction basis. Information arrives through periodic declarations or upon request. This limits the tax authorities' ability to act in real time on the taxpayer's receivables.
This difference is relevant and should be a factor in the evaluation of any invoicing system. It is not just about regulatory compliance, but about understanding the practical consequences of each model for the taxpayer's relationship with their tax authority.
Where does Spain stand on this map?
Spain occupies a middle position. It is not a pioneer like Italy nor does it have a system as advanced as Poland's KSeF, but it is not lagging either: VeriFactu is a technically robust system that covers the requirements of integrity, traceability and immutability, and offers the taxpayer something few European systems offer — the option to choose between sending records to the tax authority in real time or keeping them locally with equivalent security measures.
That flexibility is a distinguishing feature. In Italy there is no choice: everything goes through SdI. In Poland there is no choice: everything goes through KSeF. In Belgium there is no choice: everything goes via Peppol. In Spain, the taxpayer decides.
The question is whether that flexibility will survive once B2B e-invoicing (Ley Crea y Crece) comes into force and ViDA requires alignment with the European standard by 2035. Businesses that prepare now with systems capable of operating in both modes will be best positioned for whatever comes next.
