US Tax. UK Tax. High-Net-Worth Clients. International Complexity.

\n

If you're an experienced US/UK tax professional looking for a role where you can work with genuinely complex private client matters, this could be an opportunity worth exploring.

\n

We're working with a leading UK accountancy and business advisory firm with an established international network and a growing specialist US Private Client Tax practice.

\n

The team works with high-net-worth and ultra-high-net-worth individuals, entrepreneurs and internationally mobile clients, helping them navigate the increasingly complex interaction between US, UK and international tax systems.

Why this role?\n

This is a specialist private client role with exposure to far more than standard tax compliance.

\n

You'll work with clients who have complex international affairs, including foreign trusts, investments, pensions, structures and cross-border assets, providing both compliance and advisory support.

\n

You'll also work closely with experienced Managers, Directors and Partners, giving you the opportunity to develop your technical knowledge and progress your career within a growing specialist team.

Your role\n

You'll take responsibility for a portfolio of private clients, becoming a key point of contact and helping deliver a high-quality US/UK tax service.

\n

Your responsibilities will include:

\n
    \n
  • Managing a portfolio of HNW and UHNW private clients.
  • \n
  • Preparing and reviewing US tax compliance and informational reporting.
  • \n
  • Reviewing Forms and 8858.
  • \n
  • Assisting with more complex US/UK tax filings.
  • \n
  • Working on PFIC reporting and foreign trust reporting.
  • \n
  • Supporting foreign tax credit and year-end tax planning.
  • \n
  • Advising on UK non-domiciled and internationally mobile individuals.
  • \n
  • Supporting Managers, Directors and Partners on advisory projects.
  • \n
  • Identifying opportunities to develop existing client relationships.
  • \n
  • Reviewing work completed by more junior team members.
  • \n
  • Supervising and supporting off-site tax preparation teams.
  • \n
  • Managing billing and workflow across your portfolio.
  • \n
  • Getting involved in interesting ad hoc and specialist assignments.
  • \n
  • Building strong professional relationships with clients and colleagues.
  • \n
  • Supporting continuous improvement across the team.
  • \n

  • \n
  • Around 3 years' experience in US/UK tax.

  • Private client tax experience.
  • \n
  • Experience working with HNW individuals, entrepreneurs or internationally mobile clients.
