Isle of Man Taxation: Key Developments and Insights

The 2025/26 Isle of Man Budget reduced the top individual income tax rate from 22% to 21%, slightly increased personal allowances, and raised the tax cap to £220,000, aiming for modest relief for residents. Under Pillar Two, the Isle of Man has implemented a 15% domestic minimum top-up tax alongside income inclusion rules, granting transitional qualified status to provide multinationals with greater certainty. Economic substance requirements reflect global transparency standards. There is no formal transfer pricing regime, but tax authorities may adjust prices to counter avoidance. While the Isle of Man itself has no inheritance tax, UK IHT rules can affect residents with UK assets under residence-based tests.

This webinar provides one-hour of CPD and offers insights and updates from a leading industry-expert speaker.
