About EY Tax

EY Tax is a market leader, renowned for delivering sustainable growth and empowering our people to shape their own careers. Our diverse, collaborative team advises on high-profile transactions, combining technical expertise, innovation and a genuine focus on continuous development. Join us to work on challenging, multi-country projects in a supportive, dynamic environment where your impact truly matters.

The Opportunity

This is an exciting opportunity to join our US/UK Cross-Border team as a Tax Senior. You'll serve as the primary day-to-day contact for clients, managing the preparation and review of their US and/or UK tax returns. You'll collaborate closely with managers and partners, identifying tax planning opportunities and ensuring compliance excellence. This role offers the chance to handle a diverse and often complex client portfolio while building your technical and leadership skills within a supportive and high-performing team.

Key Responsibilities

• Manage an allocated client portfolio, taking ownership of the full compliance process and delegating tasks effectively.
• Demonstrate a strong understanding of your clients' affairs, becoming their main point of contact.
• Identify potential issues and planning opportunities, discussing these with senior colleagues.
• Contribute to consultancy and research projects as opportunities arise.
• Maintain up-to-date technical knowledge and apply it effectively in reviews.
• Proactively identify internal training needs for yourself and the wider team.
• Liaise with third-party professionals including solicitors, accountants, tax advisers, and financial advisers.
• Develop people management and coaching skills.
• Undertake other duties as required.

• Experience preparing and reviewing complex US and/or UK tax returns.
• Excellent client service and communication skills, both written and verbal.
• Knowledge of key tax legislation and statutory requirements.
• Awareness of corporate tax and tax planning is advantageous.
• Strong analytical and problem-solving abilities with great attention to detail.
• High numeracy and confidence interpreting financial data.
• Proficiency in relevant IT systems and tax software.
