Digita Corporation Tax software has full support for HMRC iXBRL filing including automatic tagging whilst also providing the ability for tags to be added manually. Tags are checked against HMRC requirements automatically. Incorporates the ability to review and sort tags to confirm they are valid.

iXBRL Tagging


Digita Corporation Tax software uses an intelligent information explorer tree arranged in a workflow format from most to least used schedules. Only the schedules used in a period are rolled forward to the following period meaning that you can easily see where data was entered previously.

  • Easy to follow step by step layout
  • Intelligent roll forward removes unused schedules
  • Indicators show whether a schedule is empty, contains information or is completed
