• Provide clear, practical, and commercially‑focused tax advice. Work directly with SMEs, OMBs, and larger corporates, offering tailored tax solutions that support clients’ long‑term commercial objectives.
• Mentor and develop junior team members. Review work, offer guidance, and help shape the next generation of tax talent while contributing to a positive and knowledge‑sharing team culture.
• Build and strengthen trusted client relationships. Act as a key point of contact, attending meetings, identifying opportunities, and helping clients navigate the complexities of the UK corporate tax landscape.

What We’re Looking For

• ACA/CTA qualified (or equivalent) with 3+ years of corporate tax experience, ideally gained within practice.
• Strong technical corporate tax knowledge, particularly with SME and OMB clients, and confidence in handling both compliance and advisory work.
• A proactive self‑starter comfortable working independently while also thriving in a collaborative team environment.
• Excellent project management and communication skills, able to manage deadlines, juggle multiple engagements, and clearly articulate advice to both colleagues and clients.
