Problems we Solve

As the demands of The Forum on Harmful Tax Practice (FHTP) increase over time, Tax Authorities need a system to manage ETR with partner jurisdictions.

  • Tax Authorities need to commit to transparency through the compulsory spontaneous exchange of information on taxpayer-specific rulings.
  • A solution is required that securely stores all ETR data, allows data to be easily viewed by authorised users and management reporting and analysis.
  • Jurisdictions need a solution that upgrades to ensure compliance with any future changes to OECD XML schema for ETR.

Key Benefits

Digitalise your Exchange on Tax Rulings obligations as mandated under BEPS Action 5 as part of a fully integrated and complete AEOI solution. 

  • Include ETR in a single integrated technical solution to meet all your international tax information exchange commitments.
  • Manages the sending and receipt of all tax rulings with partner jurisdictions irrespective of original format (XML, Email, Excel, Word or PDF).
  • Includes an easy-to-use web interface that displays tax rulings received via the CTS and is used to record rulings received via other channels, such as email.
