Advisory, Compliance, and Software
Operational Tax Specialists
Supporting private market funds with the processes, data, and technology that turn tax strategy into compliant execution.
We offer specialist FATCA, CRS and US withholding tax services. We support businesses with adhoc advice, compliance and US tax form validation services.
Since 2019, we’ve been developing Emprise — a modular platform designed to manage the documents, data, and relationships that sit at the heart of operational tax. Emprise centralises investor information, visualises entity structures, tracks reporting obligations, and strengthens the controls required for confident compliance.
FATCA & CRS Advisory
We work to identify each entity’s classifications and documentation requirements. We help interpret the rules, understand obligations, and implement efficient processes and controls. We offer practical advice, grounded in deep technical experience and a clear understanding of how to effectively manage obligations.
FATCA & CRS Reporting
We offer market-leading FATCA and CRS reporting services. We prepare, validate, and file FATCA and CRS reports across multiple jurisdictions, ensuring compliance with each schema’s technical specifications and deadline requirements. We offer value by using our proprietary technology platform.
Tax form review
Not only is validating US W-8/9s, FATCA, and CRS forms often required, it is essential to creating complete and accurate filings. We have market-leading expertise in form validation in addition to the emprise software which is used to track form invalidity and expiration.
Emprise and EmpriseSC
Emprise is our modular operational tax platform which uses automation to manage investor data, documents, and reporting obligations, and vizualize entity relationships with strong controls and auditability.

How can we help?
01Entity Classification
We assist with jurisdiction-specific FATCA and CRS classifications, ensuring each entity in a fund structure is correctly categorised and supported by defensible documentation. This reduces the risk of misclassification and downstream reporting errors.
02GIIN registration/de-registration
We advise on the best registration type required and the full FATCA registration process, including obtaining and maintaining GIINs, updating responsible officer details, and ensuring ongoing compliance with registration requirements.
03Manage tax authority queries and audits
We support clients in responding to FATCA and CRS inquiries, information requests, and audits from global tax authorities. Our approach ensures accurate responses, clear documentation, and strong defence of your reporting positions.
04Respond to investor queries
We assist with investor tax documentation and operational tax queries, helping funds provide clear, accurate, and timely responses. This improves investor confidence and reduces administrative burden on internal teams.
05Validate US tax and CRS forms
We conduct detailed reviews of W-8, W-9, and CRS self-certification forms to ensure completeness, validity, and compliance with IRS and OECD standards. Our validation process reduces withholding risk and prevents reliance on defective documentation.
06Identify entity FATCA and CRS reporting obligations
We analyse fund structures, investor profiles, and jurisdictional requirements to determine whether, where, and how FATCA and CRS reporting obligations arise. This ensures reporting is accurate, complete, and aligned with local rules.
07Reporting registration
We manage registrations with national FATCA/CRS reporting portals, including Cayman, UK, Luxembourg, Jersey, Guernsey, and others, ensuring entities are set up correctly and meet all prerequisite requirements.
08Reporting
We prepare, validate, and file FATCA and CRS reports across multiple jurisdictions, ensuring compliance with each schema’s technical specifications and deadline requirements. Our process improves data integrity and reduces the likelihood of rejection or penalties.
09U.S. Inbound Advisory
We advise on U.S. withholding and reporting implications for non-U.S. entities investing into U.S. assets, including treaty claims, ECI considerations, and withholding agent obligations. Our guidance helps funds structure investments efficiently while remaining compliant.
What is Operational Tax?
Operational Tax is the implementation of processes, controls, and technology that ensure the effective execution of a fund’s tax strategy — delivering financial performance, meeting investor expectations, and maintaining compliance integrity. It involves managing the data, documentation, and reporting that shape tax impacts and regulatory outcomes.
