Research complex tax questions, analyze client documents against current law, and turn your findings into client-ready work product, with the authority behind every conclusion in plain view.
General-purpose AI gives you a plausible answer. Tax work needs the controlling one.
Tax rules live within a hierarchy of statutes, regulations, treaties, administrative guidance, and case law, each with its own effective date, scope, and legal weight. General-purpose AI knows the law exists; it doesn't know how the pieces rank. Taxtune is built around that hierarchy, so you see not just the answer, but the authority behind it, the reasoning, and which rule prevails when they conflict.
THE PRODUCT
Built for precision, designed for trust
Taxtune pairs authority-aware retrieval with source-level citations, so every material conclusion can be traced back to its source.
Authority-aware search
Ranks and filters sources by legal authority, current status, and effective date.
Verifiable conclusions
Every material proposition links to its supporting source, so reviewers can check the authority without redoing the research.
Uncertainty made visible
When authorities conflict, facts are missing, or the sources can't support a conclusion, Taxtune says so instead of offering a confident guess.
Cross-border analysis
Analyze domestic law alongside applicable tax treaties in a single workflow, across supported jurisdictions and treaty pairs.
Check your documents against the law
Upload contracts, reports, and other client documents, then analyze their tax-relevant provisions against the supported legal corpus.
From research to work product
Turn finished analysis into structured memos, opinions, client communications, and internal notes, ready for professional review.
