VAT in the Digital Age (ViDA) in 2026: A Practical Compliance Roadmap for Cross-Border and SaaS Businesses

It has been just over a year since the EU formally adopted the VAT in the Digital Age package on 11 March 2025. ViDA is no longer a proposal. It is law, codified in Council Directive (EU) 2025/516, Council Regulation (EU) 2025/517, and Council Implementing Regulation (EU) 2025/518, all published in the Official Journal on 25 March 2025 and in force since 14 April 2025. The next milestones move from policy to plumbing: an updated EN 16931 e-invoice standard approved in February 2026, a Peppol ViDA pilot running through the year, the Secure IOSS pilot in development, and a wave of national mandates that pre-empt the EU-wide deadlines. If you sell digital services, run a marketplace, or move goods across EU borders, the work you do in 2026 will determine whether the 2028–2030 phases are an upgrade or a fire drill.

The legal package, in one paragraph

ViDA amends the VAT Directive 2006/112/EC and the administrative cooperation framework simultaneously. Directive 2025/516 rewrites the substantive rules on invoicing, place of supply, OSS, and platform liability. Regulation 2025/517 upgrades the IT backbone: it modernises the central VIES, adds a digital reporting database, and harmonises how member states exchange transaction-level data. Implementing Regulation 2025/518 sets the technical detail: the data fields, transmission rules, and identifier formats that allow national systems to interoperate. Reading just the directive misses half the picture; the regulations are where the real compliance work lives.

Where the timeline stands in 2026

ViDA rolls out in five waves between 2027 and 2035. Most of the visible action right now is preparation, not enforcement. The Commission spent late 2025 and early 2026 publishing the Implementation Strategy, drafting Explanatory Notes, opening the Peppol ViDA pilot, and approving the revised EN 16931 standard at CEN on 13 February 2026. Member states are running gap analyses, scoping IT projects, and (in several cases) accelerating domestic mandates to land before the EU-wide dates.

DateWhat changes
14 Apr 2025ViDA enters into force. A handful of provisions (mainly invoicing definitions, removal of the requirement for prior recipient agreement to issue an e-invoice, and member-state freedom to mandate domestic e-invoicing without derogation) apply immediately.
2026EN 16931 revision approved (Feb 2026), expected formal publication May 2026. Peppol ViDA pilot live. Secure IOSS pilot enters IT build. Member states publish national implementation roadmaps.
1 Jan 2027OSS extended to gas, electricity, heating and cooling. New call-off stock arrangements no longer permitted (existing ones run off until 30 Jun 2029).
1 Jul 2028Single VAT Registration package: OSS extended to B2C movements, transfer of own goods (“Be2Me OSS”), expanded mandatory reverse charge for non-established suppliers. Platform deemed-supplier rules become available on an optional basis.
1 Jan 2030Platform deemed-supplier rules become mandatory for all member states.
1 Jul 2030Mandatory cross-border B2B structured e-invoicing and Digital Reporting Requirements (DRR) go live. EC Sales Lists are abolished.
1 Jan 2035National domestic e-invoicing and reporting systems must align with the EU DRR standard.

Pillar 1: Digital Reporting Requirements and the EN 16931 update

The most operationally disruptive pillar is also the latest to arrive. From 1 July 2030, every cross-border B2B intra-Community supply must be invoiced using a structured electronic format aligned with the European e-invoicing standard EN 16931. Both supplier and customer feed transaction data into a central digital reporting database accessible to all member states.

The 10-day / 5-day clock

ViDA tightens invoicing deadlines significantly. The supplier must issue the structured e-invoice within 10 days of the chargeable event (the supply, or earlier payment receipt). For self-billed invoices and intra-Community acquisitions, the recipient must report the transaction within 5 days of issuance or receipt. The current rule of issuance “by the 15th day of the following month” for intra-Community supplies disappears. For finance teams that batch-invoice at month end, this is a meaningful change in operating rhythm.

EN 16931, post-February 2026

EN 16931 was originally written for B2G invoicing under Directive 2014/55. CEN approved a major revision on 13 February 2026, with formal publication expected in May 2026, that adapts the standard for B2B and adds the data fields the DRR will require. Key additions include a buyer reporting reference, expanded VAT category and exemption codes, identifiers for self-billing, and structured fields to support the platform deemed-supplier flow. If your invoicing system supports the 2017 version of EN 16931 only, it will need an upgrade.

Structured means structured. A PDF with embedded XML is acceptable only if the XML is the legal source and conforms to EN 16931 (the “hybrid” ZUGFeRD/Factur-X model). A flat PDF or scanned image will not qualify as an e-invoice for ViDA purposes. The same logic already applies under most domestic mandates: Italy SdI, Romania e-Factura, French PPF and Poland KSeF all require structured XML.

Peppol ViDA pilot

OpenPeppol, the consortium that runs the Peppol network used widely in EU and Asia-Pacific e-invoicing, has spent 2025–2026 running a ViDA pilot to demonstrate that the existing Peppol infrastructure (network, BIS Billing 3.0 specifications, four-corner model) can carry ViDA-compliant invoices and reporting messages. The pilot uses the existing access-point and SMP architecture so businesses already on Peppol can extend rather than replace what they have. National authorities are evaluating Peppol as one route to deliver ViDA reporting alongside their own domestic platforms.

Why DRR matters for SaaS

SaaS companies tend to think of e-invoicing as a B2C concern, but ViDA's DRR is a B2B framework. If you sell to EU businesses and apply the reverse charge, you are creating an intra-Community supply that lands inside DRR scope from July 2030. PDF reverse-charge invoices issued on a Stripe receipt template will not satisfy the rule. Either your billing system natively produces EN 16931 XML, or you bolt on an e-invoicing service (Sovos, Pagero, Avalara E-Invoicing, Storecove, Comarch) that converts your invoice records and transmits them. Decide which path you are on by mid-2027 to leave time for testing.

Pillar 2: Platform economy and deemed-supplier rules

From 1 January 2030 (with optional adoption from 1 July 2028), digital platforms that facilitate short-term accommodation rentals and passenger transport by road become deemed suppliers for VAT purposes when the underlying provider does not charge VAT. The rule was watered down from the original Commission proposal. The accommodation cap dropped from 45 to 30 nights, and member states retain several opt-outs. The substance, however, remains: platforms collect and remit VAT in cases where today's hosts and drivers do not.

Mechanics

The deemed-supplier model creates a fiction of two supplies: the host or driver supplies the platform (VAT-free), and the platform supplies the end customer (with VAT at the destination rate). The platform is responsible for charging, collecting and remitting the VAT, and may use a dedicated OSS return to do so without registering in every member state. Where the underlying provider is VAT-registered and confirms a valid VAT number, the deemed-supplier fiction does not apply and normal rules continue.

The SME opt-out

One of the most consequential negotiated additions is the SME opt-out. Member states may choose to disapply the deemed-supplier rule when the underlying host or driver qualifies for the cross-border SME scheme (introduced separately in 2025). For platforms, this means the deemed-supplier obligation is jurisdiction-by-jurisdiction: in some member states a small host stays out of scope, in others the platform must collect VAT regardless. Platform tax engines will need a per-supplier, per-country eligibility check.

Scope limits to remember

Pillar 3: Single VAT Registration

For most cross-border businesses, this is the pillar with the clearest upside. From 1 July 2028, the OSS becomes a substantially broader simplification, and a new mandatory reverse charge reduces the situations where a non-established supplier needs a local VAT number.

Transfer of own goods OSS (“Be2Me OSS”)

Today, when an e-commerce seller moves stock from a warehouse in Belgium to a warehouse in Germany, the movement is a deemed intra-Community supply and acquisition that requires a German VAT registration. From 1 July 2028, the seller can opt into a new OSS scheme that lets the same movement be reported via a monthly return in the country of identification, with no German registration needed. The scheme covers most own-goods movements, including stock for fulfilment-by-marketplace inventory.

Call-off stock simplification phased out

The 2020 Quick Fix call-off stock simplification disappears in two steps: no new arrangements from 1 July 2027, and the regime fully ends on 30 June 2029. Existing arrangements run off naturally. The transfer-of-own-goods OSS is the replacement.

Mandatory reverse charge for non-established suppliers

From 1 July 2028, all member states must apply the reverse charge for B2B supplies where the supplier is not established and not VAT-identified in the country of taxation, and the customer is VAT-identified there. This already exists in many member states under Article 194; ViDA makes it mandatory and harmonised across the EU. The practical effect: if you sell B2B and your customer is VAT-registered in a country where you have no establishment, you do not need to register there.

Expanded OSS for goods with installation, on-board supplies, and energy

Example: An Estonian SaaS company hires a German installer to fit IoT hardware at a Munich customer.

Pre-ViDA: The hardware-with-installation supply is a German domestic supply. The Estonian seller must register for VAT in Germany.

Post-ViDA (from 1 Jul 2028): The same supply can be reported through Union OSS under the expanded scope: one Estonian return, one consolidated payment, no German registration.

The Secure IOSS pilot

Often overlooked alongside the headline pillars, ViDA also tightens the Import One Stop Shop (IOSS) used for low-value imports up to EUR 150. The Commission identified IOSS number misuse, where fraudsters use legitimate IOSS numbers without the holder's knowledge, as a leakage point in the EUR 128 billion VAT gap. The Secure IOSS pilot, which entered IT build in early 2026, introduces tokenised IOSS identifiers and authentication steps so customs systems can verify in real time that an import is genuinely covered. Live operation is planned for late 2026, with broader rollout aligned to ViDA's main milestones.

Domestic e-invoicing mandates: the parallel reality

ViDA's 2030 deadline is a long way off. Domestic mandates are not. Several member states have used ViDA's removal of the prior derogation requirement (effective 14 April 2025) to accelerate or formalise their own systems.

CountrySystem2026 status

By 1 January 2035, every domestic system above must accept and produce EN 16931 structured invoices that interoperate with the central DRR. Until then, multinational businesses face a multi-format reality: an invoice issued in Poland goes to KSeF in FA(3) XML, in Italy to SdI in FatturaPA XML, in France through a PDP in Factur-A or UBL, and in cross-border B2B contexts increasingly via Peppol BIS 3.0. The harmonisation does not arrive evenly.

What this means for SaaS and digital-services businesses

Pure SaaS sales are a Pillar 3 story more than a Pillar 1 story, but the Pillar 1 obligations creep in faster than most people expect.

Risks and open questions

Member-state implementation drift

ViDA gives member states a number of options: when to adopt the deemed-supplier rule (2028 vs 2030), whether to apply the SME opt-out, whether to mandate domestic e-invoicing earlier than 2030, and how to interface their existing platforms with the central DRR. Expect a multi-year period of regulatory drift before everything aligns in 2035.

EN 16931 governance

The February 2026 revision is significant but not final. CEN expects continued evolution as DRR data needs are refined. Build to the standard, but expect to follow minor versions over the next 4–5 years.

Audit and dispute

Real-time reporting reduces the lag between transaction and audit. Tax authorities will be able to query mismatches between supplier and customer reporting almost immediately. Expect more contemporaneous queries and fewer multi-year retro audits, which is operationally different from today's audit cadence.

Data residency and security

Transaction-level data flows from your ERP through service providers to national authorities and into the central VIES. The Regulation 2025/517 framework includes data-protection commitments, but multinational businesses should validate where and how invoice data is stored and who in the chain has visibility.

Frequently asked questions

What is the legal basis for ViDA?

Three instruments adopted on 11 March 2025 and published in the Official Journal on 25 March 2025: Directive (EU) 2025/516 (substantive rules), Regulation (EU) 2025/517 (administrative cooperation and IT systems), and Implementing Regulation (EU) 2025/518 (technical detail). They entered into force on 14 April 2025.

What is the 10-day rule?

From 1 July 2030, intra-Community B2B invoices must be issued within 10 days of the chargeable event. Self-billed and intra-Community acquisition reporting must happen within 5 days. The current “15th of the following month” deadline is replaced.

Will domestic mandates disappear?

Not until 1 January 2035, when national systems must align with the EU DRR standard. Until then, expect parallel compliance with national platforms (Italy SdI, Romania e-Factura, France PPF, Poland KSeF, Germany B2B, Belgium Peppol, Spain Verifactu/Crea y Crece) alongside the EU framework.

How does ViDA affect a US SaaS company selling into the EU?

Non-Union OSS for B2C digital services is largely unchanged. The bigger impact is on B2B sales: from 2030, the reverse-charge invoice you issue must be EN 16931 structured. Many EU customers will demand structured invoicing earlier due to domestic mandates. Plan for an EN 16931 capability by 2027.

What is the platform SME exemption?

Member states may exclude underlying suppliers using the SME VAT scheme from the platform deemed-supplier rule. If a host or driver is below the local SME threshold and uses the SME regime, the platform is not the deemed supplier for that supply. Adoption varies by member state.

Does ViDA replace the OSS or IOSS?

No. It expands them. OSS coverage broadens from 2027 (energy) and 2028 (transfer of own goods, installation supplies, deemed-supplier OSS for platforms). IOSS continues, with a Secure IOSS pilot launching in 2026 to address number misuse. See our dedicated OSS explainer for the underlying mechanics.

What happens to EC Sales Lists?

EC Sales Lists are abolished from 1 July 2030 once DRR is fully operational. The same data flows through the structured e-invoice and digital reporting channel into the central VIES.
