Why Join Fiander ETL?
At Fiander ETL, working in tax is about more than numbers – it’s about people and impact. You’ll enjoy a supportive, collaborative environment where your contribution matters, and you’ll have the chance to develop both technical and advisory skills while maintaining a healthy work-life balance.
Your Mission
What you’ll be doing day to day
In this role, you will manage tax compliance for a portfolio of individuals, trusts, and partnerships. You’ll review tax returns prepared by junior team members, prepare returns for more complex clients, and liaise with clients and HMRC to resolve queries. You’ll also advise clients on tax planning opportunities and contribute to the ongoing development of trainees within the tax team.
Who You’ll Work With
The people you’ll collaborate with
You’ll report to a Client Director and work alongside managers and senior managers across all client-facing teams in the firm. Key relationships include client contacts, introducers such as financial and pension advisers, trainees, and other colleagues in the tax team.
What You’ll Bring
Skills and experience we’re looking for
You’ll be highly organised, proactive, and confident in communicating with both clients and junior colleagues. Previous supervisory experience is essential, and tax qualifications such as ATT or CTA are desirable but not mandatory. You’ll work collaboratively, demonstrate enthusiasm for learning, and have the ability to manage client queries and advise on planning opportunities effectively. Part-time applications will be considered.
What We Offer
The benefits and support you’ll receive
This is a varied and rewarding role with a mix of compliance and advisory work. You’ll gain exposure to a broad range of clients and personal tax matters, while contributing to the development of colleagues and trainees.
