Affinia is the UK’s largest purpose‑led, purpose‑built Accountancy firm, focused on building stronger, more valuable relationships. With over 1,000 colleagues across the East, South East, 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 team also offers in-depth sector expertise across a number of sectors, 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.

Purpose of the role: In joining Affinia, you will be part of a growing, successful, forward‑thinking and dynamic Tax department. This role is designed for an experienced corporate tax or transaction tax professional who wants to play a key role in building and delivering Affinia’s transaction tax offering.

As a Transactions Tax Manager / Senior Manager, you will work closely with Directors, Partners, Corporate Finance, Accountancy & Advisory, Audit, VAT, Employment Tax, Property Tax, Private Client and other specialist teams to provide joined‑up advice on acquisitions, disposals, restructurings and wider corporate transactions.

The role will involve supporting clients throughout the transaction lifecycle, from initial planning, proposal stage and offer terms, through to tax due diligence, acquisition structuring, completion, post‑deal implementation and ongoing advisory support.

You will work with a broad range of clients including owner‑managed businesses, family‑owned companies, entrepreneurial clients, corporate groups, management teams, investors, acquisitive businesses, professional advisers and, where relevant, private equity backed or PE‑adjacent clients.

This is an advisory‑led and commercially focused role. You will be expected to deliver high‑quality technical work, lead client relationships, support business development, contribute to the growth of the Tax Service Line and help develop junior colleagues.

We operate a hybrid working model, so you will split your time between the office, client sites when required, and home when you are able. We provide both technical and soft skills training through platforms such as Tolley’s, Mercia, Croner‑i and Linked In Learning.
