Group Tax & Treasury Manager – London

We are partnering with a dynamic, fast-growing, multi-entity business backed by private equity to appoint a Group Tax & Treasury Manager. This is a high-impact role offering broad exposure across tax, treasury, and strategic finance, ideal for a proactive individual who thrives in a standalone capacity and enjoys driving change.

The Role

Reporting to the Corporate Finance Director, you will take full ownership of the Group’s tax and treasury agenda. Operating within a highly acquisitive environment, you will ensure robust compliance, strengthen governance, and deliver practical, commercially focused tax solutions across the business.

You will be the go-to person for all tax & treasury matters, working closely with senior stakeholders to improve processes, minimise risk, and enhance efficiency—while reducing reliance on external advisors.

Key Responsibilities

• Lead UK corporation tax and VAT compliance, including filings, reporting, and statutory obligations
• Oversee tax accounting (current and deferred), group relief, and UK GAAP disclosures
• Manage transfer pricing, Corporate Interest Restriction (CIR), and thin capitalisation requirements
• Identify and deliver tax efficiencies, including R&D claims and capital allowances
• Provide expert VAT and indirect tax guidance across a complex group structure
• Support M&A activity, including due diligence and post-acquisition integration
• Own treasury activities, including cashflow forecasting, banking relationships, and cash pooling
• Due to the acquisitive nature of the business, there are now c50 bank accounts. Simplify the banking facility structure through the consolidation to one preferred supplier.
• Strengthen governance frameworks, including SAO, CCO compliance, and tax risk management
• Act as the primary contact for HMRC and support audit and investor reporting
• Drive process improvements and explore tax technology solutions

About You

A technically strong and commercially minded tax & treasury professional who is comfortable operating autonomously in a fast-paced environment. You bring a hands-on approach, a continuous improvement mindset, and the confidence to influence senior stakeholders.

Key Requirements

• Qualified accountant or tax professional (CTA, ACA, ACCA)
• 5+ years’ experience in large, complex or PE-backed organisations
• Proven experience operating as a standalone Tax Manager
• Strong knowledge of UK corporate tax, VAT, and tax governance frameworks
• Experience managing tax across multi-entity structures
• Excellent analytical, communication, and stakeholder management skills
• Advanced Excel and data analysis capability

Why Apply?

This is a rare opportunity to shape and lead the tax and treasury function within a growing, acquisitive group. You’ll play a key role in driving strategic decisions, improving controls, and creating long-term value for the business.

This position is based in central London, with an expectation of four days per week in the office initially moving to three days, post probation.
