Product · Tax
Ratio meets tax professionals in the tools they already use, connecting research, drafting and project knowledge without losing the human review that matters.
Work through complex questions with an intelligent tax agent that provides verifiable sources, including UK tax legislation and HMRC guidance where relevant.
Turn research into a structured memorandum. Ratio works with you section by section — disclaimer, executive summary, background, scope, legislative position and the main analysis — carrying the research points you save into each draft as it takes shape.
Review and edit documents directly in Word. Ratio proposes precise changes, preserves formatting and supports tracked changes for your review.
Build out spreadsheets, calculations and formulas for work such as corporation tax compliance, Pillar Two and tax reporting.
Use the context of an email to summarise threads and draft polished replies. You review and send every message yourself.
Bring conversations, saved documents and shared work together. Project conversations can draw on the knowledge your team has chosen to share.
Authoritative tax knowledge
Every part of Ratio can draw on a dedicated tax repository covering comprehensive, up-to-date UK legislation, HMRC guidance and supporting material. When that material is relevant to a question, Ratio uses it to inform the answer — and points to what it worked from.
Comprehensive, current UK tax legislation, used where it bears on the question in front of the team.
Published HMRC manuals and guidance that practitioners routinely need to apply and cite.
Related reference material that helps Ratio reason through the detail of a query before a draft is written.
Ratio surfaces the sources behind an answer so your team can verify them directly. Final judgement, review and sign-off remain with you.
