Tallia is an AI tax research and drafting platform designed for modern tax practices. Built for tax and accountancy firms and in-house tax teams, it helps professionals research complex questions, prepare advice and manage review and collaboration in one workspace. Its tools provide cited answers grounded in tax authority guidance, legislation, case law and uploaded documents, with links that let users verify sources.

Teams can turn research into memos, advice notes and letters, work with Word, Excel and PowerPoint, draft email replies from Outlook, review documents in a structured grid, and collaborate in shared project spaces. Tallia says it covers more than 35 jurisdictions and is designed to keep tax information current. The company emphasizes traceable work, confidentiality and customer control: inputs and uploads are not used to train models, and the platform offers access controls, audit logs and encrypted data.

Tallia serves teams seeking to respond faster and expand the scope of tax advice they can deliver. It is operated by Revax Technologies Limited, based in London
