Tax reimagined: Leverage the technology (r)evolution to elevate your tax function

The current state of AI in tax

The seminar opened with an overview of the current state of AI in tax, based on KPMG’s experiences with Belgian tax teams and global benchmarking insights. While awareness and experimentation with AI are high, usage today remains largely focused on personal productivity (e.g., drafting, summarization, translation). More advanced, agentic use cases embedded into tax processes are still limited, highlighting a clear gap between experimentation and scalable value creation.

Data management

A central theme throughout the event was the critical role of data management. Increasing regulatory pressure, real‑time reporting requirements (e‑invoicing, Pillar Two, digital audits), and growing scrutiny from tax authorities mean that “first‑time‑right” data is no longer optional. KPMG emphasized the importance of a common data model, standardized data sourcing, and a structured journey from raw source data to trusted, tax‑ready data that can support compliance, analytics, and AI use cases. Organizations that invest in data foundations can significantly reduce compliance effort, improve auditability, and free up capacity for higher‑value activities.

The technology journey of the tax function

The seminar also highlighted the technology journey of the tax function, particularly in indirect tax and compliance management. Key value drivers include embedded tax logic, scalable integrations across ERPs and jurisdictions, workflow and document management, and real‑time monitoring of deadlines and risks. Technology is increasingly positioned as a “must‑have” rather than a “nice‑to‑have,” enabling tax teams to move from reactive compliance to proactive risk management and business partnering.

Risk and controversies

A dedicated section on risk and controversies addressed the evolving tax risk agenda: greater transparency, real‑time data access by tax authorities, ESG scrutiny, and the growing use of advanced analytics and AI by authorities themselves. Strong tax governance, documented processes, controls, and continuous monitoring were identified as essential to remain in control.

Practical applications of Generative AI in tax

Finally, the seminar explored the practical application of Generative AI in tax. Drawing on academic research and real‑world experience, KPMG stressed that productivity gains of up to 70% are achievable, but only under the right conditions. Success depends on mindset, high‑quality and curated data, clear use cases, governance, and moving beyond generic chatbots toward agentic AI embedded in workflows. GenAI is not a replacement for tax expertise; rather, it amplifies it, enabling tax professionals to focus on judgment, insight, and strategic value.

In a nutshell

The future tax function is data‑driven, technology‑enabled, and increasingly supported by AI. Organizations that invest pragmatically, starting with strong data foundations and targeted use cases, can already realize meaningful benefits today.
