Tax Manager — Withholding Tax (In-House)
Location: London (hybrid)

About the Role
Our client, a global law firm, is looking to appoint an experienced Tax Manager to their in-house tax team, with a specific focus on withholding tax and cross-border information reporting. This is a high-visibility role for a technically strong tax professional who wants to own withholding tax compliance and advisory across a complex, multi-jurisdictional group.
The successful candidate will be the primary point of contact for all withholding tax matters, working closely with Treasury, Payroll, Legal, and external advisers to ensure the group meets its obligations under FATCA, CRS, and relevant domestic withholding regimes while managing risk and identifying efficiencies.
Key Responsibilities
- Manage end-to-end withholding tax compliance across UK and international operations, including FATCA/CRS reporting obligations
- Review and validate W-8/W-9 series forms and equivalent documentation from counterparties and payees
- Oversee preparation and filing of relevant withholding returns (e.g. UK CT61, US Forms 1042/1042-S where applicable) in coordination with external advisers
- Advise the business on withholding tax implications of cross-border payments, financing structures, and new commercial arrangements
- Monitor changes in double tax treaty positions and ensure correct application of treaty relief
- Partner with Treasury and Payroll on withholding obligations relating to interest, dividends, royalties, and employment-related payments
- Support tax authority enquiries and audits relating to withholding tax positions
- Maintain and improve withholding tax policies, controls, and documentation to strengthen SAO/Tax Governance compliance
- Provide technical training and guidance to finance and business teams on withholding tax requirements
Candidate Profile
- Qualified tax professional (CTA, ACA, ACCA, or equivalent) or a qualified lawyer with a tax specialism
- 4+ years' experience with a strong, demonstrable focus on withholding tax — in-house, Big 4, law firm, or financial services background all considered
- Hands-on experience with FATCA/CRS, double tax treaty analysis, and international withholding forms (W-8BEN-E, 1042-S, etc.)
- Strong working knowledge of UK withholding tax rules; US or broader international withholding exposure highly desirable
- Comfortable operating autonomously and advising senior, non-tax stakeholders in plain language
- Excellent attention to detail balanced with commercial, pragmatic judgement
What's on Offer
- Competitive salary in the region of £70k – £90k + discretionary bonus
- Private healthcare, pension, and standard benefits package
