Changes to employee share schemes, including Company Share Option Plan and Enterprise Management Incentives
This tax information and impact note is about changes to the rules for employee share schemes.
This measure makes changes to the Company Share Option Plan (CSOP) and Enterprise Management Incentives (EMI), which are tax-advantaged employee share schemes. It also changes certain non-tax-advantaged share options.
The measure will:

- increase the maximum exercise period for CSOP options
- extend the Employee Ownership Trusts exception in the EMI rules
- increase the EMI exercise window following disqualifying events
The changes will take effect from 6 April 2027.
