Generative AI is often framed as a tool for handling repetitive or mundane tasks. But what about its ability to automate processes and decisioning for some of the biggest data challenges tax teams are facing?

Increasing regulatory complexity, rising demands from internal stakeholders, and budget constraints are creating pressure for tax leaders to do more with less. At the same time, many tax teams are stretched by time-consuming core compliance activities.

Findings from the latest EY Tax and Finance Operations Survey show that tax personnel spend nearly half of their time – 45% – on data gathering and wrangling for routine compliance activities. Meanwhile, new regulations are expanding data requirements and reducing the time available for compiling and analyzing information for reporting.

Together the global EY organization and IBM are helping businesses rethink tax compliance and reporting with an enterprise-grade generative AI (GenAI) agent focused on scaling productivity and supporting greater business value. Building on these efforts the EY–IBM Alliance team works with organizations to apply GenAI to address critical data challenges across their tax functions.



EY teams were key in helping us change our approach to AI use cases in tax compliance. They convinced us of the role AI can play in process automation and not just textual support to reading contracts or writing responses to tax authorities. Our use cases that were jointly developed with EY teams are expected to help save tens of thousands of hours from reduced manual workload in the tax compliance processes. But we are not done yet! We expect to expand quickly to other tax processes and continue to be a shining example of IBM watsonx’s capabilities.

Enterprise-grade GenAI for enterprising tax teams

Working together, EY and IBM developed EY.ai for tax built with IBM watsonx, which is poised to help transform how tax departments function.

Streamline tax operations through AI

Achieving and maintaining meaningful efficiency and quality improvements requires sustained effort and investment. EY.ai for tax, built with IBM watsonx, helps address the data-related challenges that can limit workflow automation, supports advisory activities on demand and helps tax teams prioritize value-added activities over routine processes. It is designed to analyze millions of rows of data quickly and accurately, identifying and correcting historical errors that could otherwise trigger local audits by regulatory authorities. By streamlining data review, EY.ai for tax helps teams reallocate time to more strategic activities.
