IMEs can lead to complexities with regards to corporation tax compliance.
Share awards held by inbound IMEs may give rise to Part 12 deductions for UK host employers, based on amounts charged to UK employment income tax. These Part 12 deductions can be missed unless employers have robust processes for identifying relevant employees, tracking share acquisitions and calculating a deduction based on the amount subject to UK income tax. The interaction with any recharge payments made to a host employer may, however, need to be considered before taking a Part 12 deduction.
Outbound IMEs may also give rise to Part 12 deductions, even where the employment income is not fully taxed in the UK. Therefore, it’s important to make sure that outbound IMEs’ share awards are tracked for trailing corporation tax deductions as well as any ongoing UK payroll obligations.
Where there might be employer deductions for the same share-based employment income in the UK and in the IME’s home or host country, international groups should confirm the extent to which it would be possible to claim in each jurisdiction (and UK and other anti-avoidance rules can potentially be relevant here).
Specific consideration may also need to be given to other scenarios (e.g. branches or employees who spend part of the vesting period working in the UK but are not present at either grant or acquisition of shares).
