Protect historical zero-rated revenue with immutable consultation proof.
European tax authorities audit historical sales declarations years after transactions occur. Under Council Directive 2018/1910, failure to prove valid counterparty VAT registration at the date of supply triggers retroactive tax assessments and penalties.
The Multi-Year Tax Audit Clawback Trap
Businesses rely on Article 196 reverse-charge exemptions to invoice cross-border customers at zero percent VAT. Years later, tax auditors demand proof that each customer was an active taxable person on the invoice date. Without contemporaneous consultation records, the exemption fails.
- Tax authorities audit transactions years later when customer companies may have closed or changed tax status.
- Payment gateways discard raw verification logs, leaving finance teams with no auditable proof of validity.
- Auditors disallow exemptions and issue retroactive assessments for unpaid domestic VAT plus interest.
