When the tax authority already has your data: what happens to VAT returns and reconciliation
​


Back to the Agenda

Chris leads strategy for Avalara’s large accounting firm partnerships outside North America. Based in London, he brings a decade of global Big Four experience in VAT/GST, spanning consulting, compliance, technology, and implementation across EMEA and Asia-Pacific. 

As tax authorities move towards real-time e-invoicing and continuous transaction controls, they gain access to the same granular data that businesses use to prepare VAT returns. This raises a fundamental question: what role does reconciliation play in a world where tax authorities already hold transaction-level data?

This session explores how the relationship between invoicing, and VAT returns is evolving. It will examine the shift from periodic, aggregated reporting towards continuous alignment between business systems and tax authority data.

Attendees will gain insights into the overlapping but not completely aligned datasets of e-invoicing and VAT Reporting, explore how reconciliation processes will need to evolve and where mismatches will still arise.

The session will also outline the operational and data challenges organisations need to address now to remain in control as compliance becomes increasingly real-time and data-driven


1. Understand how reconciliation is changing in a real-time reporting environment
Attendees will understand how the traditional reconciliation process between ERP data, VAT returns, and tax authority records is being disrupted by e-invoicing and live reporting. This includes the shift from post-period validation to continuous alignment, and why reconciliation is moving upstream into transaction-level controls rather than sitting at the end of the process.


2. Identify where discrepancies will still occur despite “shared data”
Even where tax authorities receive invoice-level data, mismatches will not disappear. Attendees will learn where differences will continue to arise, including timing differences, master data inconsistencies, adjustments, and cross-border complexity, and how these will manifest in a real-time compliance model.


3. Define what a future-state operating model for VAT could look like
Attendees will leave with a view of how VAT processes may evolve in a post e-invoicing world, and leave with some practical steps organisations should take now to prepare for this shift
