Why join our client?

This is a brilliant opportunity to join a high-performing and collaborative in-house tax team within a well-established, forward-thinking organisation operating across the UK. The business has ambitious growth plans, an exciting M&A pipeline, and a purpose-driven culture, making this a fantastic time to join their evolving finance function.

You'll work in a dynamic tax team that sits at the heart of the business, providing critical support across compliance, reporting, and project work-particularly in areas such as M&A, indirect tax, SAP transformation, and sustainability-linked initiatives. Based in Maidenhead, with flexible hybrid working (3-4 days in the office), this Senior Tax Manager role offers real influence and progression potential.

How you'll make an impact

As Senior Tax Manager, you'll report directly to the UK Director of Tax & Treasury and play a key role in shaping the tax agenda for the group. Your responsibilities will include:

• Leading UK corporate tax compliance, reporting, and planning activities across multiple entities.
• Acting as a senior advisor on complex tax matters including transfer pricing, interest deductibility, CFCs, and loss utilisation.

• Playing a critical role in indirect tax and wider business projects, including SAP S/4HANA implementation.
• Reviewing tax disclosures for statutory accounts and managing HMRC enquiries.
• Supporting continuous improvement of tax governance and controls across the group.

This is a visible and commercially impactful position with broad exposure across UK and international tax, finance, and operations.

Why our client is excited about you

You're a technically strong and commercially minded tax professional with a proactive, collaborative approach. You thrive in fast-paced environments and are motivated by the opportunity to shape process, advise the business, and deliver real impact. You'll likely bring:

• A CTA and/or ACA qualification (or equivalent).
• Strong experience in corporate tax compliance and reporting, ideally in both industry and/or practice.
• Experience in indirect tax is desirable but not essential.
