The 2026 Guide to Employee Share Option Schemes (ESOS)

Share options are often pitched as the sweetener that helps a growing Singapore business attract and keep talent, but the rules around them are less well known than the headline benefit. This article, The 2026 Guide to Employee Share Option Schemes (ESOS), explains how an ESOS generally works in Singapore, how the gains are taxed, and where employers and foreign hires most often go wrong.

Who this applies to

An ESOS gives selected employees the right to buy shares in their employer, or a related company, at a fixed exercise price after a vesting period. Start-ups and SMEs tend to use them when cash is tight, while larger groups use them to reward senior staff.

The topic touches several groups:

Employers considering a scheme for Singapore-based staff, including those on Employment Pass, S Pass or Dependant’s Pass with work eligibility.
Foreign employees who receive options from an overseas parent company and are posted to Singapore.
Employees who are leaving Singapore while holding unexercised or unvested options.
HR and finance teams who must report the gains to IRAS each year.

Work Permit holders are less commonly included in schemes, but nothing in the work pass rules prevents an employer from granting options to them if the company policy allows it.

Key rules and requirements in Singapore

Singapore has no single statute called the “ESOS Act”. The rules come from several places, and an employer needs to satisfy all of them.

Company law

Under the Companies Act 1967, directors of a company generally need prior shareholder approval to issue new shares. A return of allotment is then lodged with ACRA after shares are issued. The scheme rules, the option agreement and the board and shareholder resolutions should all be consistent with the company’s constitution.

Securities law

An offer of options to employees may fall within exemptions under the Securities and Futures Act 2001 that apply to employee share schemes. Whether an exemption is available depends on how the offer is structured, so it should be checked before any invitation letters go out.

Income tax

IRAS treats gains from options as employment income. For a typical option, the taxable gain is the market value of the shares on the exercise date less the exercise price paid, and it is taxed in the year of assessment following the year of exercise. Gains are reported by the employer in the employee’s Form IR8A, with the supporting Appendix 8B. Because the tax arises on exercise rather than on grant, an employee can owe tax on a gain that is still locked up in shares that cannot yet be sold.

CPF and work pass considerations

Share option gains are generally not treated as wages for CPF contributions under the CPF Act, but the position can differ for related payments, so confirm with the CPF Board where a plan includes cash components. For work pass purposes, MOM looks at fixed monthly salary when assessing qualifying salary, and option gains are generally not counted towards it. A foreign hire cannot rely on a promised share option to meet the Employment Pass or S Pass salary threshold under the COMPASS framework or the qualifying salary rules.

Step-by-step process

A well run scheme usually follows this sequence:

Decide the purpose: retention, recruitment or reward, and who is eligible.
Draft the scheme rules, covering the vesting schedule, exercise price, exercise window, lapse conditions and treatment of leavers.
Obtain board and shareholder approvals, and update the constitution if needed.
Issue option agreements to each participant, with a clear explanation of the tax treatment.
Track vesting dates and keep an option register.
On exercise, allot the shares, lodge the return with ACRA, and update the register of members.
Report the gain to IRAS through the annual employment income filing.
For leavers, handle the cessation process described below.

Common mistakes to avoid

Treating the scheme as a purely tax matter and forgetting the Companies Act approvals and ACRA lodgements.
Failing to tell employees that tax is payable on exercise, even where the shares are illiquid.
Leaving the leaver provisions vague. Disputes over whether unvested options lapse on resignation are common.
Overlooking the tax clearance process when an employee holding options leaves Singapore. Employers generally need to notify IRAS of employees who are leaving, and IRAS may require the employer to withhold money until tax is cleared.
Promising options to a foreign candidate as a substitute for a compliant fixed salary in a work pass application.
Copying overseas scheme documents without adapting them to Singapore law.

Practical examples

Consider a Singapore start-up that grants an engineer on an Employment Pass the option to buy 10,000 shares at SGD 1.00 each, vesting over four years. If the shares are worth SGD 3.50 when the engineer exercises, the taxable gain is SGD 2.50 per share, or SGD 25,000 in total, before any tax reliefs or rates are applied. The company reports it in the annual filing, and the engineer pays tax on it even if no shares have been sold.

Now take a manager who resigns and leaves Singapore with vested options still unexercised. IRAS can treat the position on cessation specially, and the employer should seek guidance early so that the notification and any withholding are handled in time. Handling this late is one of the more expensive errors we see.

How Singapore Employment Agency can help

Singapore Employment Agency supports employers with work pass applications, renewals, appeals, HR compliance and immigration matters. When a share scheme is part of a hiring package for an overseas candidate, we can help you structure the offer so that the work pass application rests on a compliant fixed salary, and we can point you to the right corporate secretarial and tax advisers for the scheme documents themselves. We do not draft scheme rules ourselves, but we help ensure the employment side of the arrangement fits together.

Frequently Asked Questions

Is an ESOS compulsory for Singapore employers?

No. There is no legal requirement to offer share options. It is a commercial decision, although once options are granted, the contractual and tax consequences apply.

When is tax payable on share options?

Generally on exercise, not on grant. The gain is taxed as employment income in the year of assessment following the year of exercise, subject to the specific terms of the plan.

Can foreign employees on an Employment Pass or S Pass participate?

Yes, there is no work pass rule preventing it. The gains are not a substitute for the fixed monthly salary that MOM assesses.

What happens to options when an employee resigns?

It depends entirely on the scheme rules and the option agreement. Many plans lapse unvested options and give a short window to exercise vested ones, which is why the leaver clause should be written carefully.

Do I need to report option gains to IRAS?

Yes. Employers report them through the annual employment income filing, using the relevant appendix to the Form IR8A.

Key takeaways

An ESOS is governed by company law, securities law and tax rules, not one dedicated statute.
Tax generally arises on exercise, based on the gain over the exercise price.
Share options do not count towards the fixed salary used for work pass qualifying salary.
Leaver terms and the tax clearance process for departing employees deserve early attention.
Adapt any overseas scheme documents to Singapore requirements before issuing them.

Requirements may change, so always check the latest guidance from MOM, IRAS or ACRA, or consult a professional adviser.
