Employee share schemes allow companies to give employees ownership in the business as a tax-efficient way to attract, retain, and motivate talent, with different structures such as approved schemes (like EMI and CSOP), unapproved options, and all-employee plans like SIP and SAYE. Each scheme has different rules, tax treatments, limits, and levels of flexibility, with EMI generally seen as the most favorable for smaller companies and CSOP or other alternatives better suited for larger or more complex organizations. More advanced structures like growth shares, direct share ownership, and employee ownership trusts further expand how companies can design equity rewards, though they often involve more complexity and careful tax and valuation planning.
