The tax rules around enterprise management incentive (EMI) schemes are extremely generous and were introduced to enable small higher risk trading companies to recruit or retain key employees. The principal advantage is that where the option price is not less than the market value of the option shares at the time of grant, no income tax charge arises when the option is exercised. Therefore, if there is substantial growth in value of the shares between grant and exercise, that growth is liable only to CGT when the shares are sold. By contrast, if the option is non-qualifying, an income tax charge arises on exercise based on the market value of the shares at that time. CGT Business Asset Disposal Relief (formerly Entrepreneur’s Relief) is usually available for disposals of EMI shares and so the rate of CGT is reduced to only 10%, making the scheme even more attractive. This note considers the rules on a step-by-step basis.
