The Client Review feature of Digita Personal Tax compares the current year’s tax return with that of the previous year, using pre-defined criteria within the software to draw attention to the reason for differences in figures between the years. Our customers report time spent on review can be cut by up to 80%.

  • Save time and expense whilst ensuring accuracy with Client Review
  • Items are reviewed at income level rather than Tax Return box level to highlight any discrepancy
  • Fully configurable to meet your specific needs

Digita Personal Tax software is unique in that it uses 'artificial intelligence' to bring to your attention possible risks, potential tax planning opportunities as well as issues that require your attention outside of the tax return review process. This technology is named 'TaxAware' and communicates with the user through our 'Active View' display technology.

  • Highlight possible risk areas and planning opportunities in the Tax Return with TaxAware
  • Updates in real time as the Tax Return information is entered
  • Items highlighted can be configured by the user once reviewed
