Tax Director

Role can be based in any Southern office to include:
Brighton, Sutton, Orpington, Sidcup. Affinia is a UK Top 35 Accounting firm, where we support our clients with everything from day‑to‑day Accounting, Audit and Tax planning to strategic business advice, compliance and specialist services such as Cloud Accounting, Payroll and Mergers & Acquisitions across a wide range of sectors. We are committed to delivering excellence in every aspect of our work, adapting to the evolving regulatory landscape while consistently exceeding client expectations.

We focus on building authentic connections, collaboration and growth, both with our clients and colleagues with over 300 years’ experience, bringing together financial experts from across London, East Anglia & Southeast England. We have more than 600 accountancy professionals across our 15+ offices and advise businesses, government and public sector organisations and individuals in the UK and internationally across seven principal practice groups:
Accountancy & Advisory, Tax and Planning, Audit Services, Corporate Finance, Digital Solutions, Payroll and Financial Planning. We have invested continuously in technology and gained in-depth knowledge across a broad range of markets, growing through acquisitions and private investment. We offer an exceptional service to our clients, with access to our sector experts to develop the strategy that will help them reach their goals.

We keep a finger on the industry pulse, so our clients receive the best short, medium and long‑term advice.

As a Director within either our Personal or Corporate team, you will be responsible for continuing to grow our overall Tax offering within the firm both internally within the existing client portfolio but also externally through your own professional contacts and connections. This role goes beyond technical tax oversight — it is a leadership position responsible for building high‑performing teams, developing future leaders, ensuring operational excellence, and helping shape the firm’s long‑term strategic direction.

You will act as a key advisor to clients, supporting business development efforts and identifying opportunities to add value. Internally, you will oversee and mentor Managers and Senior Managers, role model the firm’s values, and contribute to service line strategy, operational projects, and change initiatives. You will take ownership of process improvements, risk management, and cross‑location collaboration, while supporting the Head of Tax in achieving team and firm‑wide objectives.

You will be required to manage a comprehensive and complex client list, provide line and performance management and make a significant contribution to ongoing growth of a successful Tax practice. You will have a direct contribution to the development and achievement of building the practice and will be required to build and maintain relationships with third parties. You will be expected to advise clients in connection with their tax affairs and onboard them to the team to offer bespoke advice.

You should already be working as an experienced senior manager or Director and looking to develop your role considerably through technical advice, client management and business development.
