Restricted Stock Units are share-based awards that give employees company shares or cash value after vesting conditions are met.
Restricted Stock Units, usually called RSUs, are a form of share-based employee reward. They give an employee a right to receive shares, or sometimes a cash amount linked to share value, after specified vesting conditions are met. Unlike ordinary shares issued on day one, RSUs do not normally give the employee immediate ownership, voting rights, or dividend rights. The employee receives the value only if the award vests.
RSUs are common in later-stage startups, multinational technology companies, and growth businesses that want to reward employees without requiring them to pay upfront for shares. They are different from share options because the employee does not usually need to exercise an option or pay an exercise price. If the vesting conditions are met, the award settles automatically or under the rules of the plan.
For Irish founders, RSUs can be useful where the company wants a structured employee incentive but does not want to issue shares immediately. They can also help attract senior hires who expect equity-style upside. However, RSUs need careful tax, accounting, and legal planning because the timing of tax charges, payroll withholding, and company reporting can be more complex than the commercial concept suggests.
An RSU award is normally made under an employee share plan or award agreement. The agreement sets out the number of units granted, the vesting schedule, the settlement date, leaver rules, and any performance or employment conditions. A common structure is time-based vesting over several years, sometimes with a one-year cliff and monthly or quarterly vesting after that.
When RSUs vest, the employee becomes entitled to receive shares or cash value. If the award is share-settled, the company issues or transfers shares to the employee. If it is cash-settled, the employee receives a payment calculated by reference to the value of the shares. The company may sell or withhold part of the award to cover payroll taxes where required.
RSUs are often easier for employees to understand than options because there may be no exercise price. If the company has value at vesting, the RSU has value. That simplicity can be attractive, but it can also create tax charges at vesting even where the employee cannot easily sell the shares to fund the tax. Private companies need to plan carefully for this liquidity issue.
Share options give an employee the right to buy shares at a fixed exercise price. The employee chooses whether to exercise, usually when the shares are worth more than the exercise price. RSUs, by contrast, usually deliver shares or cash automatically once they vest. This makes RSUs less dependent on employee action, but can make tax timing less flexible.
Options are common in early-stage companies because they can align employees with future growth while avoiding immediate share ownership. RSUs are often more common once a company has a clearer valuation, more mature finance processes, and a broader compensation strategy. Some companies use both, depending on role, seniority, market practice, and geography.
From a dilution perspective, both RSUs and options can affect existing shareholders. The company needs to account for the expected share pool, future vesting, and the impact on the cap table. Investors will review these arrangements during due diligence, especially before a funding round or sale.
Irish tax treatment can be significant. RSUs are generally taxed as employment income when they vest or are settled, depending on the structure. This can trigger income tax, USC, PRSI, and employer payroll obligations. If shares are later sold, capital gains tax may also apply to any growth after acquisition.
Private company RSUs need particular care because the employee may have a tax charge before there is a market to sell the shares. This can be frustrating for employees and difficult for employers to administer. Some companies use liquidity events, cash settlement, or net settlement mechanisms to reduce this problem.
Finally, the plan documents should be clear on leavers, bad leavers, change of control, and corporate reorganisations. If an employee leaves before vesting, the award usually lapses, but the exact treatment depends on the plan. Ambiguity can create disputes at exactly the moment when the company is growing, fundraising, or preparing for exit.
Model the tax and accounting before promising RSUs. A headline grant can look attractive, but the real value depends on vesting, tax, liquidity, and share value. Employees deserve a clear explanation of how the award works.
Use proper plan documents. RSUs should sit within a coherent employee incentive framework, aligned with employee shares, shareholder approvals, and company law requirements. Informal promises are risky and can create cap table problems later.
Review the plan before fundraising or exit. Investors and buyers will want to understand all outstanding awards, vesting schedules, acceleration rights, and tax exposures. Clean records make the process faster and protect trust with employees.
