Customer Tax Operations and Reporting Services

EY Customer Tax Operations and Reporting Services (CTORS) helps organizations meet their customer-related regulatory obligations through its integrated suite of end-to-end customer tax operation services, supported by EY teams across the globe and underpinned by leading technology.

Your business challenge

Multinational corporations and taxpayers worldwide must comply with a range of complex regulations wherever they do business. This requirement puts additional pressure and demands on already-busy teams as they:

  • Document and accurately classify customers
  • Manage customer and transaction data
  • Report customer information to global tax authorities

The responsibility to comply with multiple regulations is significant, especially so for financial institutions, given the volume and complexity of their customers. Failure to comply comes at a high financial and reputational cost.

Key features

CTORS is an integrated suite of customer tax operation services which can be provided in a modular or end-to-end approach. From start to finish, EY CTORS simplifies the complexity of customer tax operations, reduces cost and risk, and improves your customer tax function through the use of workflow, data management, analytics and governance to effectively help manage global tax regulations.


Since 2009, the EY CTORS team has been helping multinational corporations meet their customer-related reporting and operational tax obligations. Over the last decade, CTORS has evolved from advising on the US Foreign Account Tax Compliance Act (FATCA), one of the first regulations addressing tax transparency, to a detailed technology solution dealing with an ever-growing number of new cross-border regulatory regimes, including the Common Reporting Standard (CRS), Withholding Tax and other domestic reporting, US CH3/61, Mandatory Disclosure Rules – DAC 6 and tax crime.


All of EY CTORS managed services are underpinned by a suite of secure, connected, cloud-based technology solutions supporting each stage of the customer taxation lifecycle.
