Even where favourable tax treatment is unavailable, there are still ways to achieve tax efficiencies for both the employee and the company when offering share plans in the UK.
Acquisition of shares
Where shares are acquired under a share ownership arrangement, tax and (usually) both employer's and employee's NICs are due on the difference between the market value of the shares and the amount (if any) paid for them. It is unlawful to ask the employee to bear the employer's NICs which therefore becomes a cost to the company.
Loans
As mentioned above, a company might make a loan available to its employees to help them participate in a share plan (for example to fund the purchase or exercise price). It is possible to make these loans on an interest free basis but if the loan to an individual employee exceeds £10,000, the employee will be charged to tax on the difference between the interest paid and the Official Rate of interest (which can change from time to time). The employer will also incur a corresponding employer's NICs charge. The existence of anti-avoidance legislation means that it is uncommon for third parties (such as the trustee of an EBT) to make loans to employees as these can trigger automatic charges to income tax and national insurance contributions at the time the loan is advanced and is non-refundable, even if the loan is repaid.
The write-off of a loan will give rise to an income tax charge on the amount written off together with employer's and employee's NICs.
Grant of an option
No tax or NICs are payable when an option is granted (this is the case whether it is a taxable or tax-advantaged award).
Exercise of an option
Income tax is payable when an option is exercised and is charged on the difference between the market value of the shares at that time and the aggregate price (if any) paid for them. In most cases, there will also be a corresponding charge to both employer's and employee's NICs on the same amount. The exercise of a share option is one of the very few circumstances in which an employee and employer can agree that the employee will bear the employer's NICs. This helps employers manage their costs and employees can claim tax relief for any employer NIC they pay. Therefore, an additional rate taxpayer paying a combined rate of tax and NICs of 47% will have an effective combined tax and NICs rate of 55.25% on their option gain (assuming an employer's NICs rate of 15%).
Payment of Tax and NICs under PAYE
In the majority of cases, the employer is responsible for paying the tax and NICs outlined above through the PAYE collection system. Employees will be asked to agree that the tax and NICs outlined above is deducted from their salary. When exercising a share option, employees will often allow the company to sell some of the shares they acquire to fund their tax and NICs obligations. In the relatively unusual case where no NICs is payable and the tax is not collectable through PAYE, the employee will need to report the event and pay the tax due through self-assessment.
The cash payment made under a Phantom Option is subject to income tax and NICs in the same way as a cash bonus (but note, it is not possible for the employee to bear the employer's NICs under a Phantom Option).
Tax Elections
Shares awarded to employees are often subject to restrictions, such as the risk of forfeiture within a minimum employment period or limitations on when and to whom they can be sold, which have the effect of reducing their market value.
Usually, when an employee acquires shares by reason of their employment, any future growth in value of those shares will be taxed as capital gains rather than income and will not give rise to NICs. However, there is an anti-avoidance regime in the UK which can trigger additional income tax and NICs charges when the shares are sold or the restrictions lifted. Fortunately, it is possible for employers and employees to take themselves out of this regime by entering into what is known as a "section 431 election". The effect of a section 431 election is that the amount on which tax is charged when shares are acquired or an option exercised is calculated by reference to the (higher) unrestricted market value of the shares. However, this should ensure that subsequent increases in value of the employee's shares will be taxable as capital gains. Not only are capital gains taxed at a lower rate than the higher rates of income tax, they are not accompanied by a charge to NICs and employees can also use their annual CGT exemption to further reduce their tax liability.
To be valid, a section 431 election must be entered into by both the employer and the employee within 14 days of acquiring the shares. Under share option plans, it is common practice for employers to ask employees to agree to the election before an option can be exercised or as part of the award grant process.
Corporate Tax
Many companies operating employment share plans can benefit from a statutory UK corporation tax deduction when an employee is subject to an income tax and/or NICs charge. The employing company can deduct both the employer's NICs paid, and the amount on which the employee is assessed to income tax, from the company's taxable profits. The deduction is made in the accounting period during which the shares are acquired by employees, i.e., the same period when income tax becomes chargeable.
