Question 1

What is the EU ViDA directive deadline for mandatory electronic invoicing?

Accepted Answer

The European Commission's VAT in the Digital Age (ViDA) directive mandates digital real-time transaction reporting (DRR) and structured e-invoicing for cross-border B2B transactions starting in 2028, with individual member states like Germany (2025–2028), France (2026), and Poland (2026) enacting domestic mandates even earlier.

Question 2

Are standard PDF invoices still legal for German B2B commerce under the Growth Opportunities Act?

Accepted Answer

No. Under Germany's Wachstumschancengesetz, standard unstructured email PDFs or paper invoices no longer qualify as legal e-invoices starting January 1, 2025. B2B businesses must issue and receive structured electronic invoices compliant with CEN EN 16931, such as Factur-X (ZUGFeRD 2.2) or XRechnung.

Question 3

What is the difference between Factur-X, ZUGFeRD, and XRechnung?

Accepted Answer

Factur-X and ZUGFeRD 2.2 are identical Franco-German hybrid standards combining a human-readable PDF/A-3 with embedded XML (CrossIndustryInvoice). XRechnung is a pure XML-only syntax (UBL or CII) primarily used for German public sector (B2G) transactions. TaxAmp supports both formats seamlessly.

Question 4

How does the Article 196 EU Reverse Charge rule work on cross-border invoices?

Accepted Answer

Under Article 196 of Council Directive 2006/112/EC, when a supplier in one EU member state sells B2B services or goods to a registered business in another EU member state, the invoice is billed at 0% VAT (Category AE). The buyer self-assesses and accounts for the VAT in their local tax declaration. Both VAT numbers must be validated on Brussels VIES.

Question 5

How does TaxAmp's GoBD sequential cryptographic blockchain guarantee 10-year audit safety?

Accepted Answer

TaxAmp links every cleared invoice into an immutable Merkle hash chain starting with the Genesis Root Seal (Block #0). Every newly cleared invoice incorporates the SHA-256 digest of the previous invoice. If any record is altered retroactively, the cryptographic chain breaks, allowing tax auditors to mathematically verify 100% data integrity under German GoBD § 146 AO.
