Our training, opportunities, and creative freedom empower you to innovate and impact our network of over 300,000 professionals and one million alumni.

The Team

Our US/UK Cross-Border Tax team combines the best of both practices to deliver exceptional client service and global reach.

The Opportunity

This is an exciting opportunity for a Tax Manager to join EY's market-leading US/UK Cross-Border Tax team. You\'ll manage a diverse and complex portfolio of clients, ensuring outstanding client service across compliance and advisory engagements.

This role offers the opportunity to work with international clients, build deep relationships, and expand your technical expertise within a dynamic, high-performing team.

• Work with the Credit Control team to support timely payment of invoices.
• Review complex returns with accuracy and rigour, signing off completed work as agreed with senior management.
• Identify cross-disciplinary tax issues (including estate, gift, IHT, or corporate tax) and coordinate with relevant specialists.
• Coach and mentor junior team members, supporting their professional growth and performance.
• Oversee the technical, personal, and administrative development of assigned staff, escalating personnel matters as needed.
• Maintain EY\'s high standards of risk management, quality, and client service.
• Act as a role model for EY\'s values, maintaining confidentiality and professionalism in all interactions.
• Collaborate flexibly across teams, providing support to colleagues to ensure smooth and efficient operations.

About you

We\'re looking for an experienced and motivated professional who demonstrates:

• ATT qualification and US tax certification (Enrolled Agent or CPA) - CTA qualification desirable but not essential.
• At least five years\' experience in professional practice, operating at a similar level.
• Strong technical knowledge of both US and UK tax compliance and advisory work.
• Proven ability to deliver high-quality client service in person, by phone, and via email.
• Experience managing billing, reviewing and signing out returns, and overseeing junior staff.
• Excellent communication skills, both written and verbal.
• Strong organisational skills and the ability to work effectively under pressure.
• Great attention to detail and a high level of accuracy.
• Proven people management skills and the ability to build trusted relationships with colleagues and clients alike.
• Confidence to influence, persuade, and manage challenging client situations with professionalism and tact.
• The ability to work both independently and collaboratively as part of a team.
• Proficiency with relevant IT systems and tax software.

What We Offer

• Global Exposure: Work with international clients and collaborate across EY's global network.
