Tax Senior Manager​/Advisor

12-Month Contract or FTC | Day Rate or Fixed-Term | UK Based

We are supporting an international business with the appointment of a UK-based US Tax Advisor / Senior Manager to support a range of hands‑on US tax projects over a 12‑month assignment.

This role is specifically suited to a US‑trained tax professional currently based in the UK (often a US national) with direct, first‑hand experience of US tax compliance and IRS interaction. This is not a coordination or oversight role.

• Hands‑on involvement in IRS audits, including preparation, responses and direct liaison
• Preparation and review of US federal and state tax returns
• Delivery of sales tax regularisation projects across multiple US jurisdictions
• US tax support on M&A activity, including due diligence and transaction support
• Working closely with UK and US stakeholders to resolve complex US tax matters

• US tax trained and operating at Senior Manager / Advisor level
• First‑hand IRS audit and US tax return experience is essential
• Strong working knowledge of US federal, state and sales taxes
• M&A exposure from a US tax perspective
• Comfortable working autonomously in a project‑led environment
• UK‑based and eligible to work in the UK (US nationals in the UK very much encouraged)

• 12‑month assignment
• Open to day rate or fixed‑term contract
• UK‑based role with international exposure

This assignment will appeal to a US tax specialist in the UK who enjoys hands‑on delivery and complex problem‑solving rather than managing US tax at arm’s length.
