June 27, 2024

The report reveals that more than 66% of UK tax professionals either use generative AI on a regular basis or intend to do so soon, noting that an AI solution grounded in unrivaled tax content from Tolley will transform the tax industry.

London – Tolley®, part of LexisNexis® Legal and Professional, a leading provider of tax information, workflow and analytics, today announced the development of Tolley+ AI™, a generative AI solution designed to transform tax research and guidance.  Grounded in the largest repository of accurate and exclusive tax content, Tolley+ AI combines the power of generative AI with proprietary search technology.  Results on Tolley+ AI will always be backed by a verifiable, citable authority or source allowing users to check the validity of results instantly and effortlessly.

Tolley+ AI is using the same underlying and proven technology that drives Lexis+ AI®, the generative AI tool for lawyers.  Following the successful launches of Lexis+ AI in the USA, Australia and the UK, the business is leveraging the global expertise and experience of over 2,000 technologists, data scientists and subject matter experts to develop, test and validate an AI solution specifically for the UK tax industry. 

The role of generative AI in the UK tax market is of growing interest and importance.  The new Tolley® report How Generative AI is Transforming Tax Practice reveals that UK tax professionals have quickly recognized the efficiency benefits of generative AI.  The survey of 446 UK tax professionals in private and in-house practice reveals that 66% of tax professionals are either using or plan to use AI for work purposes.

The report goes on to reveal that 32% of tax professionals in private practice have made AI-related changes to their day-to-day operations.  In-house tax teams are a step ahead of their private practice colleagues, with 43% saying they have changed their ways of working, including 24% adopting new AI policies, 18% launching AI-powered tools for internal use and 14% delivering staff training.

Despite the interest in AI, 79% of UK tax professionals have some level of concern over the ethics and trustworthiness of public-access and free-to-use generative AI platforms citing “lack of trust” and “potential content hallucinations” as their main concerns.  However, 71% said they would be “somewhat” or “completely comfortable” using AI-powered tools that were grounded in proven, authoritative tax research and guidance content.

Tolley+ AI is grounded in up-to-date and exclusive Tolley tax content.  Tolley+ AI will be able to provide answers to tax questions with results that are always linked back to the underlying source.  Tolley+ AI will feature conversational search, insightful summarisation, intelligent drafting and document upload capabilities, all supported by state-of-the-art encryption and privacy technology to keep sensitive data secure. 

“AI is set to transform and revolutionize the practice of tax and it is clear that tax professionals are keen to embrace the value that generative AI can offer” commented Jon Scriven, Director of Tax Markets at Tolley. 

Gerry Duffy, Managing Director at LexisNexis UK added “By combining our advanced technological capabilities with outstanding Tolley tax research and guidance content, we will be able to help our customers accelerate their workflows, increase productivity and gain a clear competitive advantage.”

As part of the LexisNexis and RELX family, AI development at Tolley follows the RELX Responsible AI Principles, considering the real-world impact of its solutions on people and taking action to prevent the creation or reinforcement of unfair bias.
