Tax Director - UK/US Private Client Taxation About the job Tax Director - UK/US Private Client Taxation About Hoxton Tax

Hoxton Tax is the Tax division of Hoxton Wealth, providing specialist advice to high-net-worth individuals, internationally mobile clients, families, and their Trusts.

We work closely with Hoxton Wealth clients while also supporting independent clients, offering tailored solutions across UK personal tax, with a particular focus on international and global mobility matters, wealth structuring, and long-term planning.

Technology is a key pillar of Hoxton Tax's future-focused approach. We are investing in modern systems, data-driven processes, and the responsible use of AI to enhance efficiency, accuracy, and insight across our work.

As part of the next stage of Hoxton Tax's growth, we are now looking to establish a dedicated UK/US private client tax offering. This will be a new area for the Hoxton Tax team and represents an important opportunity to broaden the support we can provide to Hoxton Wealth's international client base.

Joining Hoxton Tax at this stage provides an opportunity not simply to join an established practice, but to help shape and build a new service line within a growing international tax business.

Role Overview

We are seeking an experienced Tax Director - UK/US Private Client Taxation to establish, lead, and develop our new UK/US tax offering.

This is a leadership role combining technical excellence, client relationship management, team development, and business growth. The successful candidate will be instrumental in shaping how Hoxton Tax delivers UK/US services, including working with the Head of Tax to develop the technical framework, processes, proposition, and team required to support the growth of this new area.

The role will focus predominantly on private clients and trusts, advising high-net-worth individuals, families, trustees, and internationally mobile clients with tax obligations across the UK and US.

The successful candidate will provide joined-up UK and US tax compliance and advisory services while working closely with the wider Hoxton Tax and Hoxton Wealth teams.

There is an existing opportunity within the wider Hoxton client base, particularly amongst internationally mobile individuals and families with UK and US connections.

The Tax Director will play a central role in developing this opportunity while also building an external network and bringing new UK/US clients into the business.

Key Responsibilities

Client Advisory & Technical Leadership

• Act as a trusted adviser to high-net-worth individuals, families, trustees, and internationally mobile clients with UK and US tax considerations.
• Provide integrated UK and US tax advice across a broad range of private client matters, including:

  • Application and interpretation of the UK/US Double Taxation Agreement
  • Double taxation relief and foreign tax credits
  • US federal and state tax considerations
  • US foreign asset and information reporting requirements, including FBAR and other relevant filings

• Ensure compliance work is technically accurate, appropriately reviewed, and completed in accordance with relevant filing and payment deadlines.
• Manage complex cases involving tax obligations and reporting requirements in both jurisdictions.
• Ensure UK and US compliance obligations are considered together rather than in isolation, identifying potential mismatches or double taxation issues.
• Work collaboratively with specialist advisers where matters fall outside the firm's direct scope of expertise.

Building the UK/US Tax Offering

As this is a new service area for Hoxton Tax, a key part of the role will be helping to build the proposition from the ground up.

The Tax Director will:

• Take a leading role in designing and establishing Hoxton Tax's UK/US private client service offering.
• Help define the scope of services, technical standards, processes, workflows, and quality controls required to deliver UK/US work effectively.
