Job description

Interim Tax Senior Manager (3-Month Contract)

South UK / Midlands | Largely Remote | £500 per day outside IR35

We are supporting a UK-headquartered, international technology-led business with the appointment of an Interim Tax Senior Manager to support the tax function through a period of transition and change.

This is a hands-on interim role reporting directly to an experienced Tax Director. The successful candidate will act as a true number two, providing both business-as-usual cover and process-driven improvement across the tax function.

The Opportunity

The tax team is undergoing a reset, with a need for structure, clarity and momentum. This role would suit someone who enjoys stepping into an environment where things are not yet fully documented and taking ownership to bring order, challenge existing ways of working, and get things moving quickly.

There is a strong transformational element to the role.

Key Responsibilities

• Owning day-to-day tax operations across the group, ensuring continuity during a period of change
• Supporting the Tax Director with oversight of corporate tax compliance and reporting cycles
• Reviewing and rationalising quarterly vs year-end reporting requirements to ensure effort is focused in the right areas
• Gathering, organising and validating tax data from multiple stakeholders and jurisdictions
• Building out clear, documented tax processes where little or none currently exists
• Designing and implementing a robust compliance calendar that tracks: Ownership, Timings, Status and completion
• Improving visibility and control across tax deliverables
• Acting as a key point of contact for internal stakeholders, including finance and group reporting teams
• Supporting interactions with external advisors where required
• Identifying inefficiencies and recommending pragmatic improvements to how tax work is performed
• Providing calm, decisive leadership without needing close supervision

About You

• Experienced at Senior Manager level (or equivalent) within tax
• Strong background in corporate tax compliance and reporting in a complex or international environment
• Comfortable operating autonomously in a remote-first role
• A natural self-starter who is confident taking ownership and driving change
• Direct, resilient and pragmatic. Comfortable challenging the status quo and pushing things through
• Not afraid to "roll sleeves up" and deal with incomplete information
• UK-based in the Midlands or South, with availability to meet in person occasionally
• Initial 3-month interim contract, with potential to extend
• Start date - Available to start before mid February
