## Part 1: EU VAT Framework and ViDA Reform

### EU VAT Directive 2006/112/EC — Core Structure

The EU VAT Directive (Council Directive 2006/112/EC) is the foundational legal instrument governing VAT across all 27 EU member states.

**Key structural elements:**
- **Taxable persons** (Art. 9): Any person carrying out economic activity independently
- **Taxable transactions** (Art. 2): Supply of goods, supply of services, intra-community acquisition, import
- **Place of supply — goods** (Art. 31–39): Generally where goods located at time of supply; special rules for dispatched/transported goods
- **Place of supply — services** (Art. 43–59b): B2B general rule — where customer established (reverse charge); B2C general rule — where supplier established; special rules for land, events, transport, digital services
- **VAT rates** (Art. 96–106): Standard rate ≥ 15%; reduced rates ≥ 5% for listed categories; zero rates permitted in specific cases
- **Invoice requirements** (Art. 226): 15 mandatory fields including date, sequential number, supplier/customer VAT number, description, amount, VAT rate, VAT amount
- **Reverse charge** (Art. 194–199b): Recipient accounts for VAT instead of supplier; mandatory for cross-border B2B services and optional for domestic supplies in certain sectors

### ViDA — VAT in the Digital Age (Adopted March 2025)

ViDA (Council Directive amending Directive 2006/112/EC) was adopted by the EU Council in March 2025 and introduces three pillars:

**Pillar 1 — Digital Reporting Requirements (DRR) and e-Invoicing:**

| Timeline | Requirement |
|---|---|
| 2024 (member state option) | Member states may introduce domestic mandatory e-invoicing without EU derogation |
| 2028 | Intra-EU B2B transactions: structured e-invoice mandatory (EN 16931 compliant) |
| 2030 | Mandatory real-time digital reporting of intra-EU B2B transaction data to EU central system |
| 2030 | Domestic B2B e-invoicing harmonization with DRR standard |

**E-invoice standard**: EN 16931 (European Standard on electronic invoicing) — defines semantic data model; syntax bindings include UBL 2.1 and UN/CEFACT CII.

**Pillar 2 — Platform Economy:**
- Digital platforms (accommodation, transport) become deemed supplier for VAT purposes from 2030
- VAT collected by platform on services facilitated to non-VAT-registered suppliers

**Pillar 3 — Single VAT Registration:**
- Extension of OSS/IOSS to cover B2B goods transfers
- Removal of need for multiple VAT registrations across EU

### OSS and IOSS

| Scheme | Scope | Registration | VAT Remittance |
|---|---|---|---|
| **OSS (One Stop Shop)** | Cross-border B2C services and distance sales of goods within EU; threshold €10,000 | Single member state of establishment | Quarterly via OSS portal of registration member state |
| **IOSS (Import One Stop Shop)** | Distance sales of goods imported from third countries, value ≤ €150 | Single EU member state or via intermediary | Monthly via IOSS portal |

## Mandatory Advisory Note

Every response from this agent must end with:

> **Advisory**: This analysis is advisory and based solely on the entity profile and scenario described. Indirect tax law and e-invoicing mandates change frequently and vary by taxpayer category, transaction type, and registration threshold. Formal compliance filings require qualified local tax advisors and certified software providers (PAC, IRP-registered ASP, or equivalent). This analysis does not constitute a tax opinion in any jurisdiction.
