Senior Tax Manager (Greater London)

Job Title: Tax Senior Manager (In-House) Location: London (Hybrid – Ideally 2 days/week in office) Reports To: London-based Tax Director The Opportunity You’re looking for more than a traditional tax compliance role. You want to work in a strategic, globally connected environment where your expertise directly shapes how a multinational organisation meets its tax obligations. This is your chance to step into an internal role with global scope — no clients, just impact. As Senior Manager, you’ll take ownership of international tax filings across a wide range of jurisdictions. You’ll focus on critical areas like Pillar 2 and Country-by-Country reporting, and you’ll work alongside a high-performing team that values quality, accountability, and smart collaboration. This role offers you the best of both worlds: technical depth and strategic influence, without the seasonal intensity of traditional practice work. What You’ll Do Lead Global Compliance: Oversee tax filings in 20–50 jurisdictions, ensuring accuracy, timeliness, and consistency across all submissions. Manage Pillar 2 and CbC Reporting: Stay ahead of evolving global standards, driving high-quality reporting and ensuring compliance with new regulations. Coordinate External Advisors: Scope work, manage deliverables, and review outputs from local tax advisors, ensuring alignment with internal objectives. Partner with Finance: Work closely with offshore finance teams to gather data, review calculations, and maintain an efficient compliance process. Support Tax Accounting: Provide tax journals and disclosures under IFRS, supporting year-end processes and ensuring accurate financial reporting. Engage with Authorities: Manage correspondence with tax authorities across jurisdictions, resolving issues with professionalism and clarity. What You’ll Bring You have solid UK and international corporate tax knowledge, with hands-on experience managing global compliance. You’re confident reviewing overseas tax returns and working with local advisors to ensure accuracy and completeness. You know how to interpret financial statements and extract key data for compliance and reporting purposes. You’ve contributed to tax accounting processes, including journal preparation and IFRS disclosures. You prefer a steady, consistent workflow throughout the year — not a high-pressure seasonal peak. You communicate clearly and effectively with stakeholders at all levels, both tax and non-tax. You have an interest in using technology to improve tax processes and increase efficiency. You hold a CTA (or equivalent) qualification and bring experience from practice, industry, or both. Why This Role Stands Out You’ll step into a truly internal, strategic tax role — not a client-facing position. You’ll work as part of a close-knit team where your expertise and independence are valued. You’ll benefit from flexible working arrangements and a strong, supportive workplace culture. You’ll gain exposure to a wide variety of tax regimes and international structures — with the space to do your best work.
