Job description

Join a fast-growing Private Client Tax team in Southampton that’s shaking things up by building genuinely close, trusted relationships with high-net-worth individuals, entrepreneurs, and global families. Think less “business as usual” and more “career with purpose”. We’re talking complex, multi-jurisdictional work. Global mobility. A collaborative team that’s as ambitious as it is down-to-earth. And a location that gives you both a vibrant professional hub and the ocean on your doorstep. Not bad, right? Here’s the twist: while many tax roles drown you in compliance, this one gears you up for advisory. Yes, you’ll kick off with a mix of compliance and advisory work, but the real goal? Elevating you into a fully-fledged trusted advisor to your own dynamic client portfolio. You’ll be working with:

• Owner-managed businesses
• Complex trust structures & varied asset bases

All while shaping the future of the team and mentoring juniors as you go. What makes this role stand out even more:

• Real advisory work from the get-go – Yes, there’s compliance, but your trajectory is fast-tracked towards complex advisory challenges.
• Human-first relationships – Become the trusted go-to for clients making big financial decisions that impact generations.
• Big firm backing, boutique-style culture – You’ll have access to national and international tax specialists while being empowered to shape your career in a supportive, down-to-earth team.
• Southampton = Work/life balance win – Enjoy the perks of coastal living with global clients, excellent transport links, and a collaborative office environment designed for growth.
• Clear path to more senior roles and leadership opportunities in the very near future
• Flexible working that actually works for you
• Real mentorship, development, and access to senior leaders

The ideal profile:

• CTA and/or ACA qualified (or equivalent)
• 4+ years UK Private Client Tax experience
• A head for complex tax issues and a heart for real client relationships
