Job description

Team Finance Business Unit Finance and Enterprise Business Services Requisition No. 12965 City Warwick, GB, CV34 6DA Date posted 5 November 2026

This is a broad tax role combining tax, data and AI, with exposure across multiple tax disciplines. No previous tax experience is needed, just strong analytical skills and a willingness to learn.

Reporting to a UK Tax Manager, this is a mixed tax role for an existing tax professional or an accounting or finance professional looking to broaden their experience into tax. It combines hands‑on exposure to corporation tax, VAT, employment taxes and financial reporting with opportunities to build on strengths in controls and data. The role will also provide opportunities to gain experience in process improvement, automation and AI‑enabled ways of working to improve how a major UK tax function operates. The successful candidate will be supported by experienced colleagues across the tax and finance functions.

This role will be based out of Warwick, and we’d hope to see you at least two days per week but you’re welcome to be in the office more often if that would work best for you. We’re happy to discuss any additional flexibility in working patterns or requirements that you feel could help to make this job work for you!

Corporation Tax

• Assist the external advisor with UK corporation tax computations and returns, with appropriate review and support.

• Assist with quarterly tax forecasts and instalment payments.
• Help maintain the corporate tax general ledgers in SAP and the provisioning software (Longview), including journal entries.

VAT and Other Indirect Taxes

• Support the preparation and review of VAT returns and related reconciliations, including checking the underlying data.
• Help maintain the VAT general ledgers in SAP, including journal entries.

• Assist with other indirect tax compliance or advisory support where required.

Employment Taxes

• Support employment tax reporting, including Directors' Remuneration, PAYE Settlement Agreements (PSA) and Short-Term Business Visitors (STBV).
• Liaise with payroll and finance colleagues to support timely and accurate compliance.

Data & Technology

• Support tax data management and help design, test and adopt automation and AI solutions, including validating outputs and controls.
• Extract, reconcile and analyse data to support compliance, reporting and decisions, improving data quality and reducing manual effort.
• Support process documentation and help identify opportunities to simplify, automate or improve tax processes.

Year-End Business Support

• Support the tax team through the year-end close period including support with entity level inputs, consolidation and disclosure activities
• Support with US SOX controls
• Work collaboratively with the wider finance team and other stakeholders to meet deadlines

What You'll Have

• Fully Qualified Accountant (ACA, ACCA, CIMA etc).
• Strong analytical ability and a willingness to build tax knowledge.
• Some exposure to tax, accounting or financial reporting.
• Strong numeracy and financial literacy preferably with an accounting or tax related professional qualification
• Practical knowledge of UK tax or the ability and motivation to develop it quickly.
• Curiosity about how automation and AI can improve tax processes, controls and decision-making.
• Good technology skills and a willingness to work with data and learn new applications and technologies.
• Good written and verbal communication skills with the ability to explain outputs to a potentially non-tax or non-finance audience.
• Energised by working collaboratively across a team and across wider business projects
• Self-starter capable working off own initiative and at pace when required.
