Help shape the UK's energy future with the Tax Manager opportunity at the Civil Works Alliance (CWA), supporting Sizewell C. As part of the CWA, you will support the building of Sizewell C, a 3.2-gigawatt power station generating low-carbon electricity for around 6 million homes and playing a key role in our energy future.
The Tax Manager is responsible for the delivery and oversight of employment tax compliance and advisory across the BBBYLO Civil Works Partnership and BBBYLO Services Ltd, while supporting broader UK tax matters (CIS, VAT, RDEC) at a managerial level. The role focuses on employment tax and IR35 as core priorities, with responsibility for coordinating wider tax deliverables, identifying risks, and escalating complex technical matters to specialist IP tax teams where required.
Operating within a complex construction and infrastructure alliance, the role requires strong employment tax expertise, sound judgement across other taxes, and the ability to manage stakeholders and deliverables rather than deep technical specialism in all areas.
