Custody tax oversight
Protocol monitors your custodian's withholding tax recovery service to ensure it's working effectively and helps you get the most out of what your custodian offers.
The independent control layer for global withholding tax leakage
Our software platform Protocol reveals unnoticed losses, quantifies their financial impact, and governs recovery outcomes across global investment portfolios — preventing leakage from recurring.
Solution
Our leading solution Protocol
Organized by fund, custody account, year, and investment country, Protocol consolidates all relevant information — income data, reclaims received and outstanding, recovery progress, required actions, and upcoming deadlines — into a single, continuously updated dashboard. It gives institutional investors and asset managers an up-to-date overview of their global withholding tax position every time they log in.
Optimize your
withholding tax recovery
Protocol captures custody tax services gaps and non-custody tax reclaims as they arise, preventing delays or forfeiture. Automated task prioritization and notification helps meet dealines and boosts withholding tax recovery.
Operational
excellence and efficiency
Protocol automates custody tax data validation and reconciliation, and streamlines workflows — replacing manual spreadsheet analysis and reducing time spent on withholding tax recovery.
Comprehensive
oversight and control
All custody tax data is continuously validated and consolidated in a single source of truth. Monitor recovery progress, track every reclaim, and access the full history of your global withholding tax position whenever you need it.
Services
Custody tax oversight and global withholding tax reclaim
A comprehensive withholding tax recovery strategy has two components: ensuring your custodian's recovery service is performing as it should, and pursuing the reclaim opportunities your custodian does not cover. We help institutional investors and asset managers with both, powered by Protocol.
Global withholding tax reclaim
Protocol identifies the non-standard withholding tax opportunities that fall outside the scope of your custodian's service offering.

The decision clarifies the beneficial ownership analysis for unit-linked structures and sets out the conditions under which foreign insurers can pursue similar refund claims.
