Introduction

UK tax-year end planning is not about rushing to contribute before 5 April. It is about understanding allowances, thresholds, taper exposure, and unintended triggers such as the MPAA. High earners and company directors benefit most when pension contributions, remuneration strategy, and carry-forward are assessed together rather than in isolation.
