Affinia is the UK's largest purpose-led, purpose-built accountancy firm, focused on building stronger, more valuable relationships. With over 1000 colleagues across the East, Southeast, London and the Midlands, we are dedicated to supporting our clients, colleagues and communities.

We advise businesses, public sector organisations, charities and individuals throughout the UK and internationally across six Service Lines – Accountancy & Advisory, Tax and Planning, Audit & Assurance, Corporate Finance, Payroll and Corporate Recovery. Our teams also offer in-depth sector expertise, ensuring our clients receive the best short‑to‑medium and long‑term advice, tailored to them. We are committed to delivering excellence in every aspect of our work, adapting to the evolving technology and regulatory landscape while consistently exceeding client expectations.

Our people are our most valuable asset. We are therefore committed to supporting our colleagues throughout their professional development, providing guidance and training at whatever stage of their career they join us.

In joining Affinia, you will be part of a growing, successful, forward‑thinking and dynamic tax department.

As a Senior, this role is about solidifying core technical expertise in your relevant field and applying it consistently to your work. We want to see you take more ownership of client work and begin contributing to team development and business growth. This role is a crucial stepping stone, where you consolidate technical skills while beginning to stretch into client and team leadership.

Excellent teamwork and communication skills are essential.

The role requires an experienced individual of Personal Tax compliance processes and workflow, along with ample opportunity to get involved in high‑value advisory work for a varied portfolio of individuals.

We operate a hybrid working model, so you will split your time between the office, client sites when required, and from home when you are able.

If completing your professional qualifications, we will of course support you in this regard and would anticipate that you be able to finalise your chartered qualifications (i.e. CTA). We provide ongoing training to develop your ‘soft’ skills such as coaching and leadership, as well as access to Croner‑i’s CPD and technical library and some elements of Mercia.
