The Opportunity

Baker Thornton has been engaged by a highly regarded mid-market tax and advisory firm in London to identify a US/UK Tax Senior (dual handler) to join their growing global mobility team. This is not a pure compliance “production line” role, it’s an opportunity to step into a more rounded position combining complex compliance with genuine consulting exposure and a clear path to grow with the practice.

You’ll be joining a collaborative team that sits at the heart of the firm’s international offering, working closely with senior stakeholders on cross‑border mobility, expat, and payroll-related issues for an international corporate client base.

The Role

This Senior US/UK Tax Senior (Global Mobility) role will suit someone already operating in the dual handler space who is ready for greater ownership of corporate portfolios, direct client contact, and increased advisory responsibility. Typical responsibilities will include:

• Managing a portfolio of corporate global mobility programmes and expatriate assignee populations, overseeing US and UK tax compliance for internationally mobile employees.

• Preparing and reviewing US and UK individual tax returns for assignees and senior executives, including more complex and high‑profile cases.

• Advising corporate clients on global mobility and expatriate tax issues, including tax equalisation policies, hypothetical tax, shadow payroll, and assignment structuring.

• Liaising with corporate clients, assignees, payroll providers, and internal teams to resolve technical and practical issues in a timely manner.

• Supporting broader advisory projects around global mobility policy design, cross‑border assignment structuring, cost projection, and tax risk management.

• Contributing to the growth and development of the firm’s US/global mobility tax capability, bringing an entrepreneurial mindset to process improvement, technology use, and service development.

You will have room to shape the role as the US/global mobility practice continues to grow, with opportunities to mentor and support more junior team members as the team scales.
