Job Description

Tax Senior Manager - 6-Month Fixed-Term Contract with Permanent OpportunityBerkshire / Surrey, UK £75,000-£90,000 + Benefits (Permanent Role)

We are supporting an international private equity-backed business, headquartered in the UK, with the appointment of a Tax Senior Manager on an initial 6-month fixed-term contract, with the clear potential to transition into a permanent leadership role.

This is an excellent opportunity for an experienced tax professional looking to step into a broader leadership position, playing a key role in both the day-to-day management of the tax function and its wider transformation.

The Opportunity

The tax function is currently led by an Interim Head of Tax and requires an experienced, hands-on tax professional to provide immediate support through a critical period, including year-end close, audit, and the management of the group's tax compliance cycle.

Alongside this, the business is undertaking a significant finance and tax transformation programme. The Interim Head of Tax is leading the tax workstream, and this role will provide valuable support in helping shape tax processes, governance, and operating best practice.

This position will suit someone who thrives in a fast-paced, evolving environment. Someone equally comfortable delivering core compliance and reporting obligations while contributing to longer-term change.

Key Responsibilities - Initial 6-Month Contract

  • Ownership of the group tax compliance calendar, ensuring deadlines and deliverables are met accurately and on time
  • Leading tax support for year-end close and external audit requirements
  • Supporting the development and implementation of tax policies, controls, and compliance processes
  • Partnering with the Interim Head of Tax on wider tax matters, including transformation initiatives
  • Acting as a key tax contact for internal finance stakeholders and external advisors

Permanent Opportunity (Following Successful Transition)

Subject to mutual agreement following the initial contract period, the role will transition into a permanent Tax Senior Manager / tax leadership position, reporting to the Finance Director.

Responsibilities will include:

  • Leading the group tax function
  • Ownership of all tax compliance, reporting, governance, and planning activities
  • Supporting the development and execution of tax strategy aligned to business objectives
  • Acting as a trusted advisor to finance leadership and wider business stakeholders
  • Managing relationships with external advisors and tax authorities where required
  • Driving continuous improvement across tax processes, controls, and governance

About You

You will likely be an experienced Tax Senior Manager (or equivalent) with a strong track record of delivering in fast-paced, commercially focused environments.

You will bring:

  • Broad tax experience spanning compliance, reporting, international tax, and advisory
  • The ability to operate independently, take ownership, and deliver with minimal supervision
  • Experience working within a robust tax governance and control framework
  • A pragmatic, commercially minded, solution-focused approach
  • Strong stakeholder management skills, with confidence engaging across finance leadership and external advisors
  • The credibility and leadership presence to step into a future tax leadership role
  • The flexibility to attend the office as required within a hybrid working model

  • Full-time salaried fixed-term contract (not interim day-rate)
  • Competitive salary and benefits package
  • Pension included
  • Reporting to the Interim Head of Tax (with close interaction with the Finance Director)
  • Start date: ASAP

Permanent Role (From Month 7)

  • £75,000-£90,000 base salary
