Accounting firms lack efficient tools to review complex tax returns year-over-year, forcing reliance on manual Excel tracking to maintain context and spot anomalies.

Existing tax preparation software does not provide built-in year-over-year comparison view with critical fields to streamline review, so preparers must manually maintain a separate spreadsheet.
