AI Application on Transactional Data Reveals VAT Outliers

Why Attend

VAT has become one of the most data-intensive and high-risk tax areas for multinational organizations. Across the EU, persistent VAT gaps, increasing regulatory pressure, and the move toward mandatory real-time reporting and e-invoicing are pushing both tax authorities and businesses to rethink how VAT compliance is monitored and controlled.


At the same time, VAT data is often fragmented across ERP systems, invoice platforms, and manual processes. Reliance on spreadsheets, inconsistent reconciliation between invoices and journal entries, and jurisdiction-specific VAT rules make it difficult to detect errors early. As a result, VAT risks often surface only during audits, when remediation becomes costly and disruptive.


This webinar focuses on how AI applied to transactional data can change that dynamic. By using AI-driven outlier detection, VAT risks can be identified proactively, before filings or audits, and integrated into ongoing tax control frameworks. Rather than replacing VAT specialists, AI reshapes their role by shifting focus from manual review to oversight, interpretation, and control.


Attending this session will help participants understand:

  • Why VAT is under increasing scrutiny from tax authorities

  • How AI-driven outlier detection supports co-compliance and pre-audit controls

  • How VAT specialists’ roles evolve in AI-enabled environments

  • How to reduce VAT risk through earlier detection and better data controls


The session is designed for organizations that want to move VAT compliance from reactive correction to proactive risk management.


Topics Covered

The webinar provides a structured walkthrough of how AI can be applied to VAT-relevant transactional data, supported by concrete use cases.


Key topics include:

  • Why VAT is under the AI spotlight: The EU VAT gap, regulatory developments toward real-time reporting and SAF-T, and the increasing use of digital detection tools by tax authorities.

  • What an AI-powered VAT outlier detection engine is: The evolution from rule-based checks to machine learning-driven anomaly detection using ERP transactional data, invoice metadata, and jurisdiction-specific VAT rules.

  • How AI affects the role of VAT specialists: How responsibilities shift from manual transaction review to interpretation, governance, and strategic oversight for in-house teams, advisors, and tax authorities.

  • Use case 1: VAT reconciliation: How AI supports periodic VAT reconciliation by adapting to historical observations, ensuring completeness of postings, and maintaining an up-to-date VAT profile.

  • Use case 2: Reverse charge logic violations: How AI identifies incorrect VAT treatment caused by missing or incorrect determination logic and adapts to evolving reverse charge rules across jurisdictions and industries.

  • Use case 3: Inter-company invoice inconsistencies: How AI detects anomalies between group company postings and proposes corrective actions based on company-specific facts and historical findings.

  • Preparing data for AI analysis: Understanding upstream and downstream data flows, cleaning ERP transactional data, and evaluating data lake versus federated models.

  • VAT data governance and risk reduction: How ISO-certified processes, AI auditability, and combined AI and human review workflows build trust in automated VAT controls.


The focus throughout is on embedding AI into existing tax control frameworks rather than treating it as a standalone detection tool.


Who Is This For

This webinar is intended for professionals responsible for VAT compliance, control, and transformation:

  • VAT specialists and indirect tax professionals: Who want to improve accuracy, reduce manual effort, and gain earlier visibility into VAT risks.

  • In-house tax and finance teams: Responsible for VAT reporting, reconciliation, and interaction with tax authorities.

  • Tax technology and data professionals: Involved in ERP data extraction, analytics, and AI-enabled control frameworks.

  • Advisors and consultants: Supporting organizations with VAT risk assessments, co-compliance models, and digital audits.

  • Organizations preparing for real-time VAT reporting: That need scalable, auditable controls over high-volume transactional data.


This session is particularly relevant for companies operating across multiple jurisdictions with complex VAT profiles.
