For Singapore startups and growth-stage SMEs, an Employee Share Option Scheme (ESOP) — sometimes called a Share Option Plan or Employee Stock Option Plan — is one of the most powerful tools available to attract senior hires, retain key engineers, and align long-term incentives with shareholder value. It is also one of the most commonly mishandled, because the scheme touches company law, employment law, securities regulation and income tax all at once.
This guide walks Singapore directors through how an ESOP works, the corporate steps required to set one up, the tax treatment for employees and the company, and the most common drafting mistakes founders make.
What an ESOP Is — and Isn’t
An ESOP is a contractual arrangement under which a Singapore company grants employees (and sometimes directors and consultants) the right to purchase ordinary shares in the company at a pre-agreed exercise price after a vesting period. ESOPs are options, not shares — the employee owns nothing until they exercise.
ESOPs should be distinguished from:
- Restricted Share Plans (RSPs) / Restricted Stock Units (RSUs) — actual shares (or rights to shares) that vest over time; no exercise price.
- Phantom Shares / Share Appreciation Rights (SARs) — cash bonuses tied to share value movements; no real shares ever issued.
- Direct Share Issuances — the employee receives shares now; suitable for very early hires before any meaningful valuation exists.
The right scheme depends on the company’s stage, dilution tolerance, and whether the employees have the cash to fund an exercise price. For early founders, see our guides to convertible notes and SAFEs and preference shares to think about the wider capital stack.
Step 1: Decide the Size of the Option Pool
Most Singapore venture-backed companies set aside an option pool of 10%–15% of the fully diluted equity post-Series A. Earlier-stage companies often start with 5%–7% and top up at each fundraising round. The pool size is normally negotiated with incoming investors and is reflected in the term sheet — investors typically insist the pool be created pre-money so that founders bear the dilution.
Build a clean capitalisation table from day one. See our piece on how to allot and transfer shares in a Singapore company for the mechanics of share movements.
Step 2: Draft the Plan Rules
The Plan Rules are the master document. They typically cover:
- Eligibility (employees, directors, consultants, advisors)
- Maximum scheme size (% of issued share capital)
- Exercise price methodology (fair market value at grant, or fixed nominal value for early hires)
- Vesting schedule (commonly 4 years with a 1-year cliff)
- Acceleration on a change of control (single trigger vs double trigger)
- Good-leaver / bad-leaver treatment on departure
- Treatment on death, disability, retirement
- Lock-in / clawback provisions if the employee competes after leaving
- Administration committee (usually the board or a remuneration committee)
- Adjustment mechanism for share splits, capital reductions and bonus issues
The Plan Rules need to be drafted in tandem with the company’s constitution. If your constitution restricts the directors’ power to allot shares, the constitution must be amended before the scheme can operate.
Step 3: Pass the Shareholder Resolution
Under Section 161 of the Companies Act 1967, the directors need a general authority from shareholders to issue shares — including pursuant to an ESOP. The resolution usually:
- Approves the Plan Rules
- Authorises directors to grant options up to the agreed pool size
- Renews automatically at each AGM (subject to listing rules for listed cos)
For a refresher on shareholder resolutions, see our note on Board Resolutions vs Shareholder Resolutions.
Step 4: Grant Options and Issue Option Certificates
For each grant, the company should:
- Pass a board resolution approving the grant (name, number of options, exercise price, vesting schedule)
- Issue an Option Certificate to the employee, signed by both parties
- Record the grant in an Options Register kept by the corporate secretary
- Update the company’s cap table to reflect the outstanding (unvested and unexercised) option pool
Step 5: Exercise — and Issue the Shares
When an employee exercises a vested option, the company must:
- Receive the exercise price (usually by bank transfer; some Plans allow “cashless exercise” by net settlement)
- Pass a board resolution allotting the shares
- File a Return of Allotment with ACRA via BizFile+ within 14 days
- Issue a share certificate and update the Electronic Register of Members
- Pay stamp duty if applicable
Tax Treatment in Singapore
Employee Side
Employees are taxed on the “gain on exercise” — i.e. the difference between the market value of the share at exercise and the exercise price paid. This is treated as employment income under Section 10(1)(b) of the Income Tax Act and reported in Form IR8A in the year of exercise (not the year of grant). Subsequent capital appreciation after exercise is generally not taxable, as Singapore does not have a general capital gains tax.
Special rules apply to options granted before an employee starts work in Singapore and exercised later, and to options granted while in Singapore but exercised after the employee leaves — a “deemed exercise rule” applies on cessation of Singapore employment.
For broader context on employment-related tax reporting, read our Tax on Employee Benefits in Singapore 2026 (Appendix 8A).
Company Side
The company is generally entitled to a tax deduction for the cost of the ESOP if it incurs cash to buy shares back from the open market to satisfy the exercise (treasury share or trust-funded plans). Where the company issues new shares on exercise, the deduction is generally not available because no cash outflow occurs.
This interacts with the treasury share regime in a way many Singapore companies overlook — review the funding mechanism with your tax adviser before going live.
Common Drafting Mistakes
- No 1-year cliff. Options that begin vesting from day one create real friction when an early hire leaves at month 6.
- Forgetting good-leaver / bad-leaver. Without these clauses, a terminated-for-cause employee can keep vested options and exercise later. Most plans require forfeiture on bad-leaver events.
- Vague exercise price. “Fair market value as determined by the board” invites disputes. Anchor the exercise price to the most recent priced funding round or an independent valuer’s number.
- Forgetting change-of-control mechanics. Acquirers expect vested options to be cashed out at deal price and unvested options to either accelerate or roll into the acquirer’s plan. Without clear drafting, a sale gets messy.
- Missing securities law analysis. Singapore exempts most internal employee share grants from prospectus requirements (Section 273(1)(b) of the Securities and Futures Act), but the exemption has conditions. For overseas grantees, the home-country securities laws also apply.
- No ACRA filings on exercise. The Return of Allotment is mandatory and triggers updates to the shareholder register.
ESOP Administration Going Forward
Once granted, an ESOP needs to be maintained alongside the company’s other corporate registers — Register of Members, Register of Directors, RORC, and the Options Register. Failure to keep these synchronised typically surfaces during due diligence in the next fundraising round, and a messy options ledger can delay a Series B by months.
Year-end, the company also needs to:
- Issue IR8A appendices for all employees who exercised options in the YA
- Track the ESOP-related accounting charge under SFRS(I) 2 (share-based payments) for the financial statements
- Disclose the ESOP in the directors’ report and notes to the accounts

How Raffles Corporate Services Helps
We set up Singapore ESOPs end-to-end: drafting the Plan Rules with our panel law firms, preparing the constitution amendments, drafting the shareholder and board resolutions, handling the Return of Allotment on each exercise, and updating the statutory registers. Our tax team prepares the IR8A reporting at the end of each YA and coordinates with the company’s auditors on the SFRS(I) 2 charge.
If you are still pre-incorporation, start with our Singapore Holding Company Structures (2026) guide to decide where the ESOP shares should sit.
