## The Problem

Senior reviewers spend hours tick-and-tying Corporate Tax returns against source documents and prior year — and small-dollar variances still slip through into partner review.

## What We Build

AI reconciles each line of the return against source docs in Thomson Reuters ONESOURCE and the prior year, explains variances over 5%, and produces a review workpaper the senior can sign off on — cutting review time in half.
