Tax Data Governance
Master data remediation and governance for tax-correct-at-source systems
Missing PEPPOL Participant Identifiers, placeholder TRN values, incorrect emirate subdivision codes — master data problems are the most common cause of e-invoicing and VAT compliance failures, and they’re set months or years before a return is ever filed. Fixing them retrospectively is a correction exercise. Fixing them at the point of product or customer setup is governance.
What's included
Scope of the engagement
