Generally, if an employer rewards an employee with unapproved shares, Income Tax and National Insurance Contributions will be charged on the difference between the market value of the shares and any amount paid towards them, in the same way as a salary or bonus.
If, however, EMI options are granted at market value there will be no charge to Income Tax or National Insurance Contributions at either grant or exercise of the options. Prior agreement of the value of the company shares at grant can be obtained from HMRC.
For example, if the value of the shares has increased substantially at the date of exercise, the employee will only be required to pay the agreed market value at the date of grant, satisfying this condition and ensuring that no Income Tax charge will arise. Once the options have been exercised, any subsequent disposal of the EMI shares will fall within the Capital Gains Tax regime and therefore any uplift in the value of the shares will be subject to the lower rates of Capital Gains Tax (in comparison to Income Tax rates of 20%, 40% and/or 45%/50%).
Importantly for the employer company, upon exercise of the options, the company can usually claim a Corporation Tax deduction equalling the market value of the shares at exercise less the amount paid by the employees. The employer also benefits from National Insurance Contributions not being payable.
