International Tax Assistant Manager (in-house)

Job description

A fantastic opportunity has arisen for an International Tax Assistant Manager to join the in‐house tax function of a leading international law firm. This is a newly created role within a collaborative, well‐regarded team that supports the firm's global operations across the UK and EMEA.

About the RoleReporting directly to the Senior Tax Manager, you will play a central role in delivering high‐quality international tax support to the firm. This is a broad, hands‐on position that offers genuine variety and high-impact work, including exposure to:

Permanent Establishment (PE) analysis and maintenance

International tax compliance across multiple jurisdictions

Advisory support on cross‐border matters, partner movements, and firm structuring

Transfer Pricing assistance (policy review, documentation, and coordination with global advisors)

Supporting tax risk management initiatives across the network

Liaising with overseas offices to ensure consistent, compliant tax processes

Working closely with Finance, Legal, HR, and external advisors

Experienced in International Tax, Corporate Tax, Transfer Pricing, or a mixed-tax role

Comfortable analysing cross‐border issues and keen to broaden your technical expertise

Someone who thrives in a collaborative, supportive team culture

Why Join This Firm?

A genuinely supportive and friendly culture — the team is known for being approachable, collaborative, and invested in development

Close exposure to senior leadership; we placed their Head of Tax, who is excellent to work with

A newly created role with real scope to shape and grow

High-quality international work with full training and development

Hybrid working model offering flexibility and work‐life balance

Strong long‐term career progression within a respected global firm
