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.

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.

Global withholding tax reclaim

Protocol identifies the non-standard withholding tax opportunities that fall outside the scope of your custodian's service offering.
