Lately, a lot of sellers have been asking me:
“I heard the EU has reformed its VAT system again. What does ”electronic invoice’ mean?”
“What does it mean for the platform to ‘treat us as suppliers”? Will the platform deduct our profits directly in the future?”
“My accounting system is still using paper invoices. Is it too late to switch?”
Instead of answering each question one by one, let’s take a moment to clearly outline the key points and timeline of the EU VAT reform—once you’ve read through this, you’ll have all the answers.
If you need assistance with designing an EU VAT compliance solution, you can also contact our online customer service representative (WeChat: JXH23314) to arrange for a consultant to answer your questions, provide professional advice, and offer end-to-end one-on-one service.
Last year, a seller client who specializes in cross-border B2B trade contacted us, saying that his partner in Germany had suddenly sent an email stating that invoices must now be in a structured electronic format, and PDFs would no longer be accepted.
He didn't think much of it at the time; he felt that “That's a bit of an exaggeration.” ...but upon further investigation, we discovered that paper invoices and PDF invoices are increasingly becoming synonymous with “non-compliance” in cross-border B2B transactions within the EU.
This isn't a preview; it's a policy that has already been implemented.
What is ViDA? It was officially approved in March 2025.
On March 11, 2025, the Council of the European Union formally adopted the “VAT in the Digital Age” (ViDA) reform package.This reform package has only one core objective: to fully digitize the EU’s VAT system.
Cross-border B2B Electronic Invoices + Real-time Filing: Cross-border B2B transactions will be required to use structured electronic invoices, and transaction data must be reported to the tax authorities in real time.
Platform “Deemed Supplier” Rule: VAT responsibilities in the platform economy have been reassigned; platforms are legally “deemed to be sellers” and are obligated to withhold and remit VAT.
Single VAT Registration System: To reduce the burden of registering in multiple countries, sellers can file VAT returns for multiple countries through a single member state using the One-Stop Shop (OSS) mechanism.
The reform affects all sellers who sell products in the EU—regardless of whether you're located within the EU or not.
Three key deadlines, each more pressing than the last
The ViDA reform is not a one-size-fits-all approach; rather, it will be implemented gradually in three phases. Compliance requirements are becoming stricter at every level. ...leaving sellers with an increasingly narrow window of time to prepare.
Milestone 1: Starting in January 2027—Expansion of the OSS Reporting Scope
Effective January 1, 2027, the One-Stop Service (OSS) mechanism will be expanded to cover the cross-border supply of energy products such as natural gas, electricity, heating, and cooling. These supplies will be treated as distance sales and may be reported for VAT purposes through the OSS.
Milestone 2: Starting in July 2028—Short-term rental and passenger transport platforms will be treated as “deemed suppliers”
Effective July 1, 2028, new “deemed supplier” rules will apply to sellers on short-term rental and road passenger transport platforms; the platforms will be considered service providers and will be responsible for withholding and remitting VAT. If you operate a short-term rental or passenger transport business on platforms like Booking, Airbnb, or similar services, the platform will automatically withhold VAT before settling your payments. This means your profit will be reduced by that amount.
Phase 3: Starting in July 2030—Mandatory electronic invoicing for cross-border B2B transactions + real-time data reporting
Effective July 1, 2030, cross-border B2B transactions within the European Union must use structured electronic invoices (compliant with the EN 16931 standard), and transaction data must be submitted digitally to the tax authorities within 10 days of the invoice date.
Paper invoices, PDF invoices, and unstructured formats—all are void.
From 2027 to 2030, the regulations will become stricter with each passing year. The sooner you prepare, the lower the cost; the later you start, the higher the cost.
The Three Questions Sellers Care About Most
✅ Q1: What exactly is an electronic invoice?
An electronic invoice is not simply “sending a PDF.” A true electronic invoice is a machine-readable, structured data format that tax authorities can process automatically.
✅ Q2: How does being “deemed a supplier” affect me?
The result is that, after the platform withholds and remits VAT, your take-home profit is directly reduced—and this reduction cannot be fully offset by adjusting prices. This system is already in effect for B2C sales by non-EU sellers and will be extended to short-term rental and passenger transport platforms starting in 2028.
✅ Q3: What happens if I don't upgrade the system?
Starting in 2030, cross-border B2B transactions that do not meet electronic invoice standards will not be accepted by tax authorities or business partners. Paper invoices and PDF files will no longer be considered compliant for cross-border B2B transactions within the European Union.
If an electronic invoice cannot be issued, the transaction cannot proceed.
This isn't a question of “whether or not to make the change”; it's a mandatory requirement—if we don't make the change, we simply can't move forward.
The core rationale behind the EU’s ViDA reform is clear: to ensure that every transaction is transparent, traceable, and reported in real time.
