Client Case Studies
A selection of recent matters — illustrating the depth and breadth of our tax advisory work and the tangible outcomes we deliver.
Corporate Reorganisation Ahead of Private Equity Investment
A mid-market business was at risk of collapsing a PE deal — or shareholders absorbing a seven-figure tax bill. We designed a multi-step restructuring plan under tight deadlines that utilised statutory reliefs without disrupting the transaction.
Inheritance Tax Planning for Family Business Owner
A family business owner faced a projected IHT liability of over £3M. We separated trading and investment activities to unlock full BPR, then implemented a phased programme of lifetime gifting, a family investment company, and trust arrangements.
EMI Scheme Setup Saves Tech Startup Employees £280K
A fast-growing tech startup wanted to grant share options to 12 key employees but faced 45% income tax on unapproved options. We secured HMRC valuation assurance, drafted the EMI plan, and managed all 92-day notifications within 6 weeks.
We are comfortable working alongside law firms and other advisers as part of a wider advisory team.
