FAQ
Answers to frequent questions about Synergen and how it can benefit your tax and treasury teams.
Synergen is a specialised software solution that automates transfer pricing calculations and generates audit-ready documentation for cash pools. It calculates arm's length interest rates, including cash pool benefit allocations, to help ensure OECD-aligned transfer pricing compliance.
Insufficient documentation or unsubstantiated cash pool rates and synergy allocations can result in tax authorities recharacterising transactions as disguised profit-shifting. This results in tax adjustments, penalties, and double taxation.
Synergen automates the manual processes around transfer pricing requirements for cash pools. This helps:
- Save time on tax compliance and transfer pricing reporting activities
- Support consistent, defensible, OECD-aligned transfer pricing outcomes and audit readiness
- Improve visibility into cash pool positions, interest payables, and risks
- Keep the process in-house without relying heavily on spreadsheets or external advisors
- Scale cash pool operations without increasing resources
Synergen is highly configurable to support your specific structure, such as in-house banks, multi-currency physical and notional cash pools. For a full list of supported features and configurations, please get in touch.
