Can an employer of record support equity and stock option plans?

An employer of record can support equity and stock option plans, but it cannot administer them directly. The EoR acts as the legal employer for payroll and compliance purposes, while equity plans remain the responsibility of the client company that grants them. Understanding where those boundaries sit is essential before you extend equity to internationally employed staff.

This distinction matters most for companies using an EoR to hire in the Netherlands or other markets without a local entity. The questions below unpack the practical and legal dimensions of equity compensation in EoR arrangements.

What types of equity compensation do international employees typically receive?

International employees most commonly receive stock options, restricted stock units (RSUs), employee stock purchase plans (ESPPs), or phantom equity. Each instrument gives the employee a financial stake in the company’s performance, but they differ significantly in how and when value is transferred, and how they are taxed in the employee’s country of residence.

Stock options grant the right to purchase shares at a predetermined price, usually after a vesting period. RSUs represent a promise to deliver actual shares once conditions are met. ESPPs allow employees to buy shares at a discount through payroll deductions. Phantom equity, sometimes called a cash-settled plan, mimics share ownership without transferring actual equity, making it administratively simpler across borders.

For companies hiring internationally, the choice of instrument often comes down to tax efficiency in the target country. In the Netherlands, for instance, stock options are taxed at the moment of exercise, which can create a significant liquidity challenge if the shares are not yet publicly traded. RSUs and phantom equity may offer more predictable tax outcomes for both employer and employee.

Why is equity administration complex for employer of record arrangements?

Equity administration is complex in EoR arrangements because the legal employer and the economic employer are two different entities. The EoR holds the employment contract and runs payroll, but the equity is granted by the client company, which has no direct employment relationship with the worker in that jurisdiction. This structural split creates ambiguity around who is responsible for withholding, reporting, and remitting taxes on equity income.

When an employee exercises a stock option or receives vested RSUs, a taxable event typically occurs. In a standard employment relationship, the employer handles withholding and reports the income to the tax authority. In an EoR arrangement, the EoR may not have visibility into the equity event at all unless the client company notifies them proactively. If the EoR is not informed, the withholding obligation can fall through the cracks, exposing both the company and the employee to penalties.

There are additional complications around social premiums. Depending on the jurisdiction, equity income may be subject to social security contributions in addition to income tax. The EoR, as the registered employer, may bear legal responsibility for those contributions even if the income source lies outside its payroll system. This requires close coordination between the client’s equity plan administrator, its legal counsel, and the EoR.

Can an employer of record administer stock options on behalf of a client?

An employer of record cannot administer stock option plans on behalf of a client company. Equity plan administration requires the granting entity, typically the client, to manage the cap table, issue grant agreements, track vesting schedules, and coordinate with a transfer agent or equity management platform. These functions sit outside the scope of what an EoR provides.

What an EoR can do is handle the payroll-side obligations that arise when an equity event creates taxable income. Once the client notifies the EoR that an employee has exercised options or received vested RSUs, the EoR can process the resulting tax withholding and social premium contributions through payroll, and report the income correctly to the relevant tax authority.

This requires a clear information-sharing protocol between the client and the EoR. The client must communicate equity events in advance, provide the gross value of the benefit, and confirm whether the income should be treated as employment income or capital gains under local rules. Without this process in place, the payroll and tax treatment of equity awards will almost certainly be handled incorrectly.

How does vesting and taxation work for EoR employees with equity?

For EoR employees, vesting schedules are set and managed by the client company, not the EoR. The tax treatment of vested equity depends entirely on the laws of the country where the employee is tax resident, which in an EoR context is typically the country where the EoR is registered and the employee works.

Vesting schedules remain the client’s responsibility

Standard vesting arrangements, such as a four-year cliff with monthly vesting after year one, are documented in the equity grant agreement issued by the client company. The EoR has no role in setting, modifying, or tracking these schedules. The employee’s employment contract with the EoR will typically reference the existence of an equity plan without specifying its terms, since the EoR is not a party to the grant.

Taxation at the point of exercise or vesting

In the Netherlands, stock options granted to employees are taxed at the moment of exercise, not at grant. The taxable benefit is calculated as the difference between the market value of the shares at exercise and the exercise price paid. This amount is treated as employment income and is subject to income tax and potentially social premiums. The EoR must process this through payroll once notified by the client.

RSUs follow a different pattern. The full market value of the shares at vesting is typically treated as employment income in the year of vesting. Again, the EoR must be informed of the vesting event and the value of the shares on the vesting date in order to process the correct withholding.

Cross-border complications arise when an employee has worked in multiple countries during the vesting period. In those cases, tax authorities may apportion the equity income across jurisdictions based on the proportion of the vesting period spent in each country. This is a significant compliance challenge that requires specialist tax advice, not just EoR payroll support.

What should companies do before offering equity to EoR employees?

Before extending equity compensation to employees hired through an EoR, companies should complete three steps: obtain local tax advice on how the equity instrument will be treated in the employee’s country of residence, establish a formal communication protocol with the EoR for reporting equity events, and review whether the employment contract accurately references the equity arrangement without creating unintended obligations for the EoR.

The first step is non-negotiable. Tax treatment of equity varies significantly by country and by instrument. What works efficiently in one jurisdiction may create a liquidity problem or an unexpectedly high tax burden in another. A tax adviser with expertise in the relevant jurisdiction should review the plan design before any grants are made.

The second step is operational. The client company needs to designate a point of contact who will notify the EoR of all equity events, including the type of event, the employee affected, the date, and the gross taxable value. This notification must happen before payroll is processed for the relevant period. Retroactive corrections are possible but create administrative friction and potential interest charges.

The third step protects both parties legally. The EoR’s employment contract with the worker should acknowledge the existence of the client’s equity plan but make clear that the EoR has no obligations under it. This prevents disputes if the equity plan is modified, cancelled, or if the employee’s EoR arrangement ends before full vesting.
