A fast-growing international advisory firm is seeking an M&A Tax Assistant Manager to join its expanding Tax Services team. The firm offers deep expertise across deals, advisory, and restructuring, delivering tangible outcomes for global businesses, investors, and stakeholders facing complex challenges and critical decisions.

Independent and conflict-free, the organisation is known for its commitment to integrity and excellence. Its diverse teams bring together specialist technical knowledge and deep sector experience across a broad range of service lines.

Since its foundation, the firm has grown rapidly and now operates across the UK, Ireland, France, Germany, Austria, Spain, BVI, Cayman Islands, Bermuda, Barbados, and Hong Kong.

Key Responsibilities

• Manage tax due diligence and structuring engagements to deliver high-quality M&A tax services.
• Review and prepare complex corporation tax returns for both solvent entities and those in insolvency processes.
• Build and maintain strong relationships with clients and internal stakeholders to support delivery and identify new M&A tax opportunities.
• Mentor and develop junior team members, fostering a high-performance culture and collaborative team environment.
• Lead transaction tax engagements related to restructurings and refinancing.

• Demonstrable experience in M&A tax or broader corporate tax advisory experience
• Strong UK corporate tax compliance expertise, including proficiency with AlphaTax.
• Excellent interpersonal and communication skills, with the ability to engage confidently with clients and colleagues.
