E-invoicing deadlines 2027: The country-by-country compliance roadmap
|
Your AP team just got comfortable with Germany's e-invoicing rules.
Now Slovakia has a January 2027 deadline, Italy's compliance model is about to shift under the EU's VAT in the Digital Age (ViDA) reform, Spain just locked in its own timeline, and more countries are lining up behind them.
Each new deadline on this list carries a real cost if you miss it: a rejected invoice, a blocked payment, or a VAT deduction you can't claim until the paperwork clears.
That's the real reason this list keeps growing.
This guide breaks down where every major market currently stands, from live mandates to markets where nothing is planned yet.
If your business operates in more than one of these markets, the country-by-country view matters less than the pattern underneath it.
Key takeaways
- Missing a deadline carries real costs: rejected invoices, blocked payments, and delayed VAT recovery
- Belgium, Germany, Poland, Romania, and several Peppol markets already have live B2B e-invoicing requirements
- France is mid-rollout, with the next phase due September 2026
- Slovakia (Jan 2027), Italy (Dec 2027), and Spain (Oct 2027) all have confirmed deadlines this year
- The UK's mandate is confirmed for April 2029, with 2027-2028 as the preparation window
- The US has no federal or state e-invoicing mandate, and none is currently proposed
- Businesses operating across multiple countries face a compliance problem that compounds with every new market
What is an e-invoicing mandate?
An e-invoicing mandate is a government requirement that businesses issue, receive, and report invoices in a structured electronic format.
PDFs and paper invoices don't qualify.
Mandates specify the accepted format, such as XRechnung, FatturaPA, or Peppol BIS, the transmission method, and the phase-in dates by company size.
For the fundamentals of how e-invoices differ from a PDF sent by email, see our complete guide to eInvoicing.
Most current mandates in Europe trace back to the EU's ViDA initiative, covered in more depth in our breakdown of VAT in the Digital Age, which aims to harmonize e-invoicing and real-time reporting across all member states by 2030.
Live now: Countries already enforcing e-invoicing
Several markets have already moved past the deadline. If you're selling into these countries today, e-invoicing is a current operating requirement.
Poland: KSeF
Poland's national e-invoicing system, KSeF (Krajowy System e-Faktur), routes B2B invoices through a centralized government platform.
Every invoice is validated by the tax authority before it reaches the buyer, which means format errors block delivery entirely, they don't surface later in an audit.

Belgium requires structured e-invoices via the Peppol network for all VAT-registered B2B enterprises as of January 1, 2026, and it took what's often called a "big bang" approach: one date, all businesses, no staggered rollout by company size.
Germany took the opposite path. Every business has had to be able to receive structured e-invoices since January 1, 2025.
Issuing is phased: businesses above €800,000 in turnover must issue e-invoices from January 1, 2027, and the requirement extends to every remaining business from January 1, 2028.
If you want the format-level detail, our guide to ZUGFeRD and Navigating EN 16931 cover Germany's specific requirements.
Denmark, Luxembourg, and Sweden currently mandate e-invoicing for incoming invoices only.
Your business needs to be able to receive them; issuing requirements haven't been extended to these markets yet.
Romania
Romania requires B2B e-invoicing through its national e-Factura system, one of the earlier movers in this wave and a useful reference point for how quickly a "planned" mandate can become a live one.
In progress: France's phased rollout
France is mid-transition, and it's worth watching closely because its five-corner model, a public platform plus certified private partners, is one of the more complex architectures in Europe.
Every business must be able to receive e-invoices starting September 2026.
Issuing obligations are staggered by company size, with large and mid-sized enterprises required to send electronic invoices from September 1, 2026, and the requirement extending to SMEs and micro-enterprises by September 1, 2027.
Full detail on the French timeline and its deferral provisions is in our breakdown of Facturation Électronique 2026.
Confirmed and locked in: What's coming next
Three countries have locked in 2027 milestones, and a fourth confirmed mandate lands just after.
Slovakia's January 2027 mandate
Slovakia's Parliament approved its e-invoicing law on December 9, 2025, and the mandate takes effect January 1, 2027.
From that date, all VAT-registered businesses must issue and receive structured e-invoices for domestic B2B transactions, using a Peppol-based model with near-real-time reporting to the tax authority.
Cross-border transactions follow later, from July 1, 2030, aligning with the EU's broader ViDA timeline.
Unlike Germany or France, Slovakia isn't easing into this with a size-based phase-in.
The obligation applies to VAT taxpayers broadly from day one, invoicing deadlines shrink to 15 days, and there's no recipient consent requirement standing in the way.
Italy's 2027 turning point
Italy's situation is different, and easy to misread. Italy has run mandatory domestic B2B e-invoicing through its Sistema di Interscambio (SdI) platform since 2019, well ahead of most of Europe.
The trigger is the EU derogation that let Italy keep running SdI as an independent system. That derogation expires December 31, 2027, right as ViDA's cross-border e-invoicing rules take effect across the EU.
In practice, this means Italy's early-mover advantage comes with a catch.
Systems built around SdI's domestic FatturaPA format now need to support EN 16931-compliant formats and connect to the Peppol network for cross-border traffic, on top of everything already in place.
A system built for 2019's requirements won't carry Italian operations through 2027 unchanged.
Spain's newly confirmed mandate
Spain's Council of Ministers approved the Royal Decree implementing its long-pending Crea y Crece B2B e-invoicing law on March 24, 2026.
Large companies with turnover above €8 million are expected to come into scope around October 2027, with all other businesses following roughly a year later.
The exact months still depend on a Ministerial Order that hadn't been finalized as this guide was written, so treat those dates as directionally solid rather than locked to the day.
Spain's mandate layers a new B2B e-invoicing and invoice-status reporting requirement on top of its existing SII real-time VAT reporting system, which has run since 2017. Businesses will exchange invoices either through accredited private platforms or the government's own public solution, in formats aligned to EN 16931.
The UK's 2029 mandate
The UK doesn't have a live e-invoicing mandate yet, but the deadline is locked in: mandatory e-invoicing for all VAT invoices, covering both B2B and B2G transactions, takes effect April 1, 2029.
The government confirmed this at the 2025 Autumn Budget, with the technical roadmap and expected Peppol-based four-corner model due at Budget 2026.
That leaves 2027 and 2028 as the UK's real preparation window, running alongside the other deadlines above.
Our guide to e-invoicing in SAP covers where the UK's requirements currently stand.
Where the US stands: No federal mandate, but movement underway
The United States has no federal or state-level B2B e-invoicing mandate, and none is currently proposed.
If your invoicing footprint is US-only, none of the deadlines in this guide apply to you directly.
Some groundwork is underway anyway.
Federal agencies already require an electronic invoice option from suppliers, via the Treasury's Invoice Processing Platform for B2G transactions.
The Federal Reserve-backed Business Payments Coalition has also built the DBNAlliance, a voluntary, Peppol-style B2B network. It processed its first live invoice in March 2024.
For a US-based company operating internationally, the more useful question is whether your platform already handles the countries where a mandate does apply.
Why multi-country compliance is the real challenge
Here's the pattern underneath the country list. Each new market you add brings:
- A different invoice format to support
- A different transmission network or portal to connect to
- A different phase-in schedule to track, on top of the ones you're already tracking
- Rules that keep shifting after you've implemented them: Germany's threshold changes again in 2028, Italy's derogation ends in 2027, Slovakia's cross-border rules land in 2030
A point solution built around one country's format buys you compliance in that market and a fresh integration project for the next one.
A platform built to handle multiple formats and networks from the start turns each new mandate into a simple configuration update.
How Doxis simplifies multi-country e-invoicing compliance
If you're tracking more than one line on this roadmap, the country-by-country approach becomes the bottleneck on both sides of the transaction.
Doxis Billing for SAP dispatches outbound e-invoices in the format each country requires, through Peppol access points and portals like SDI and KSeF.
Doxis Invoice Automation for SAP handles inbound the same way, matching invoices against the PO and goods receipt in SAP.
Both sides connect to the same audit-proof archive and your Order-to-Cash and Purchase-to-Pay processes, so you configure once and add countries as new mandates land.
With Doxis, you get:
- One platform covering outbound billing and inbound invoice processing, across every market you operate in
- Native Peppol network access, plus direct connections to portals like SDI and KSeF
- AI-powered extraction and three-way matching for inbound invoices against SAP purchase orders
- Configurable rules that keep both invoice flows compliant as new countries are added
Manufacturing leader SEW-EURODRIVE saw a 336% ROI and payback in under six months with Doxis, per a Forrester TEI study.

E-invoicing deadlines: Frequently asked questions
What is the e-invoicing deadline for 2027?
Multiple deadlines fall in 2027. Slovakia's domestic B2B mandate takes effect January 1, 2027. Germany's e-invoicing issuing requirement extends to businesses above €800,000 in turnover from January 1, 2027. Italy's EU derogation for its independent SdI system expires December 31, 2027.
Which countries have confirmed e-invoicing mandates for 2027?
Slovakia, Italy, and Spain all have confirmed 2027 milestones. Germany's phased issuing requirement also has a 2027 threshold for mid-sized businesses, ahead of full compliance in 2028.
Is Spain's e-invoicing mandate confirmed?
Yes. Spain's Council of Ministers approved the implementing Royal Decree on March 24, 2026. Large companies are expected to come into scope around October 2027, with the rest of the market following about a year later, though the exact months depend on a still-pending Ministerial Order.
What format does Slovakia require for e-invoicing?
Slovakia's mandate uses a Peppol-based model aligned with the European Norm (EN 16931), with near-real-time reporting to the Financial Directorate for domestic B2B transactions from January 1, 2027.
Does Italy's existing e-invoicing system change in 2027?
Italy's domestic FatturaPA-based system, run through the Sistema di Interscambio (SdI), stays in place on its own. The trigger is the EU derogation permitting Italy to run SdI independently, which expires December 31, 2027, requiring alignment with the EU's harmonized cross-border e-invoicing rules under ViDA.
When does the UK's e-invoicing mandate take effect?
April 1, 2029, for all VAT invoices covering B2B and B2G transactions. The UK government confirmed this at the 2025 Autumn Budget, though the full technical implementation roadmap isn't due until Budget 2026, and 2027-2028 is the window businesses are expected to use for preparation.
Does the United States have an e-invoicing mandate?
No. There's no federal or state-level B2B e-invoicing mandate in the US today, and none is currently proposed. Federal agencies require an electronic option for B2G invoicing, and a voluntary Peppol-style network called the DBNAlliance is gaining adoption, but neither amounts to a legal requirement for private-sector businesses.
What happens if my business doesn't meet an e-invoicing deadline?
Non-compliance consequences vary by country and typically include financial penalties, rejected invoices, and delayed VAT deductions. Requirements are also enforced at the point of transmission in clearance models like Italy's and Poland's, meaning a non-compliant invoice may not reach the recipient at all.
How is ViDA connected to these country-level deadlines?
The EU's VAT in the Digital Age (ViDA) initiative sets the direction that most individual country mandates are aligning toward, with full EU-wide harmonization targeted for 2030. Country-level 2026 and 2027 deadlines are largely national implementations moving ahead of, or in step with, that broader timeline.
Do I need different software for each country's e-invoicing mandate?
Not necessarily. Country-specific point solutions are common but create a growing maintenance burden as more mandates come into effect. Platforms that support multiple formats and networks from a single system, like Doxis Billing for SAP, let you add countries without a new integration project each time.
