How the EU's VAT in the Digital Age package imposes a strict 10-day issuance window and near real-time Digital Reporting Requirements for cross-border B2B transactions.

Quick Answer
Under EU ViDA (mandatory July 2030 for cross-border B2B), businesses must issue structured e-invoices in EN 16931 format within 10 days of the chargeable event. Invoice data must then be transmitted to tax authorities in near real-time via Digital Reporting Requirements (DRR) — replacing the existing EC Sales List.
EU VAT in the Digital Age (ViDA) is a package of legislative reforms adopted by the European Council to modernize VAT reporting across the EU. ViDA introduces mandatory structured e-invoicing and near real-time digital reporting for cross-border intra-EU B2B transactions.
The three pillars of ViDA are: (1) Digital Reporting Requirements (DRR) replacing EC Sales Lists; (2) updated VAT treatment of the platform economy; and (3) a single VAT registration regime. The 10-day rule falls under the first pillar.
Under ViDA, businesses conducting cross-border B2B transactions must issue a structured e-invoice within 10 days of the chargeable event — typically the date of supply of goods or completion of services.
Trigger Event
The chargeable event — typically the supply of goods or completion of services
Deadline
10 calendar days after the chargeable event
Required Format
Structured e-invoice compliant with EN 16931 (UBL 2.1 or CII XML)
Scope
Cross-border intra-EU B2B transactions
Mandatory From
July 2030
This is a significant departure from current practice, where many EU businesses issue invoices within 15 days of the month-end following the supply. Under ViDA, that extended window is eliminated for cross-border B2B — the 10-day clock starts at the supply event itself.
ViDA mandates the use of structured e-invoices compliant with the EN 16931 European e-invoicing standard. EN 16931 defines the semantic data model — the mandatory and optional fields — that a compliant e-invoice must contain.
Two XML syntaxes comply with EN 16931: UBL 2.1 (Universal Business Language) and CII (UN/CEFACT Cross Industry Invoice). Both are used within the PEPPOL network. France's Factur-X hybrid format also embeds a CII XML payload compliant with EN 16931.
UBL 2.1
Standard XML syntax for PEPPOL BIS Billing. Widely supported across EU member states.
CII XML
UN/CEFACT syntax used in France Factur-X and some German implementations.
Digital Reporting Requirements (DRR) are the mechanism by which invoice data is transmitted to EU tax authorities under ViDA. Unlike the current periodic EC Sales List — filed monthly or quarterly — DRR requires near real-time reporting of transaction data.
Under DRR, the structured e-invoice data is transmitted to the relevant tax authority's reporting system within the 10-day window. This creates a continuous transaction control model for cross-border B2B, similar to what Spain (SII), Italy (SDI), and France (ViDA-aligned) already operate domestically.

Digital Reporting Requirements (DRR)
For any EU-established business — or non-EU business with EU VAT registrations — that conducts cross-border intra-EU B2B sales, ViDA requires a fundamental change to invoice workflows.
Invoice generation must be automated
Manual invoice creation cannot reliably meet a 10-day window across high-volume cross-border transactions. Automated e-invoice generation on the day of supply is the only scalable approach.
ERP/accounting systems must output EN 16931
Your systems of record must be capable of producing UBL 2.1 or CII XML that passes EN 16931 schema validation. PDF invoices are not compliant.
A DRR transmission pipeline is required
Beyond issuing the invoice, you need a mechanism to report transaction data to the relevant EU tax authority portal within the 10-day window.
EC Sales List processes become obsolete
Current periodic ESL filing processes will be replaced by DRR. Finance teams should plan for this transition ahead of the July 2030 deadline.
No. The ViDA 10-day rule and DRR apply to cross-border intra-EU B2B transactions. Domestic B2B invoicing remains subject to each member state's own rules, which vary.
Late issuance constitutes a breach of the ViDA reporting obligation. While specific penalty structures depend on member state implementation, late reporting under DRR is expected to trigger fines consistent with existing VAT compliance penalty regimes.
Yes, if a non-EU business holds EU VAT registrations and conducts intra-EU B2B supplies, it falls within scope. Non-EU businesses using the OSS (One Stop Shop) registration may also be affected.
Yes. Factur-X embeds a CII XML payload compliant with EN 16931, and is used by France for its own e-invoicing mandate. Factur-X satisfies the ViDA format requirement for cross-border transactions.
AutoFact AI generates EN 16931-compliant UBL 2.1 and CII invoices automatically on the day of supply — eliminating the manual workflow risk that makes the 10-day window difficult to meet at scale.
