The tax landscape for global share plans is intricate and varies between countries. In the UK, there are a number of share plans that can benefit from tax advantages such as Enterprise Management Incentive Plans (EMI), Company Share Option Plans (CSOPs), Save-as-you-earn Plans (SAYE) and Share Incentive Plans (SIPs). Similar regimes can be found internationally such as Incentive Stock Options (ISOs) or Employee Share Purchase Plans (ESPPs) in the US, or free share arrangements in France.
Finding locally tax efficient arrangements
While consistent tax treatment is desirable, this is often unattainable due to differing rules and rates. In the UK, businesses may favour capital gains treatment over an arrangement that is taxed as income because of significant differences in the way in which employment income and capital returns are taxed.
In other countries, this distinction may not exist or may be less relevant. Therefore, the potential savings of adopting a locally tax efficient arrangement must be weighed against the added complexity and cost of both implementation and ongoing maintenance.
Timing of tax charges
Although the tax treatment of share options or awards will vary from country to country, the key is to avoid so-called 'dry' tax charges where employees have to pay tax before receiving any realised benefit (for example, on the grant of a share option that hasn't yet vested or become exercisable). Global share plans should be designed to ensure that, if at all possible, tax charges and withholding obligations are only triggered when the participant receives value.
It is important to note, however, that some countries have specific tax rules that apply to deferred compensation, such as the 409A regime in the US. Therefore, assuming that deferral is a tax neutral act, without getting appropriate legal advice, could lead to unexpected (and unwelcome) tax consequences.
Payment of tax charges
It is essential that local payroll and finance teams are fully briefed on how the global share plan works and when and how tax withholding obligations will arise.
Some multinational groups opt to implement a uniform "blended" tax rate at the point of tax withholding, often calculating the deduction at the highest possible rate. This approach simplifies administration but requires a subsequent "truing up" process, where employees are reimbursed or, occasionally, required to repay any shortfall through their local payroll arrangements. Importantly, if this method is adopted, it must be clearly incorporated into the share plan documentation to establish a valid legal basis for potential adjustments.
Recharging costs
Some countries allow local employers to claim a corporate tax deduction for the recharged costs of operating a group share plan on a proportional basis. This can offer tax efficiencies across the group, but it is a potentially complex process. Internal finance and accounting teams play a key role and should be involved early to ensure the structure remains tax-efficient and operationally feasible, even if they are not part of the initial design phase.
Reporting obligations
Ongoing monitoring and reporting should also be maintained across the group. Establishing a timely internal reporting policy supports accurate and effective information exchange between the parent company and its subsidiaries, facilitating compliance with reporting requirements at both local and group levels.
Robust internal reporting systems also support effective management of leavers, ensuring correct handling of tax and accounting matters when employees exit the plan or the business. By setting clear internal guidelines, companies can manage compliance risks and minimise last-minute reporting issues.
