How Employee Stock Options Work Across Asia: Country by Country

Employee stock options are becoming an increasingly important part of startup compensation across Asia.

For early-stage companies, an Employee Stock Option Plan or ESOP can help attract talented people without putting all the pressure on cash salaries. For employees, options create an opportunity to participate in the future value of the company they are helping to build.

But there is one major complication.

There is no single set of ESOP Asia rules.

An option plan that works perfectly in Singapore cannot simply be copied into Thailand, Malaysia or Vietnam. Tax timing, reporting requirements, company law and cross-border rules can change from one country to another.

For founders building regional teams, understanding these differences before granting options can prevent expensive problems later.

Key Takeaways

• ESOPs are generally used to give employees the right to acquire company shares in the future, usually after completing a vesting period.

• Tax treatment varies significantly across Asia. Some countries tax employees when options are exercised while others may delay taxation until shares are sold or transferred.

• Regional startups should design the plan centrally but review each country locally. Tax withholding, payroll reporting, securities rules and employee documentation may all differ.

How Does an ESOP Work?

A typical startup ESOP starts with the company creating an option pool.

For example, a startup might reserve 10% of its fully diluted shares for employees.

An employee could then receive 20,000 options with an exercise price of USD 1 per share. The employee does not normally receive all 20,000 shares immediately.

Instead, the options vest over time.

A common structure is a four-year vesting schedule with a one-year cliff. That means the employee earns the right to exercise part of the options after the first year then continues vesting the remaining options over the following three years.

There are four important stages:

Grant: The employee receives the right to buy shares later.

Vesting: The employee earns those rights over time.

Exercise: The employee pays the exercise price and converts vested options into actual shares.

Exit or sale: The employee may eventually sell those shares during an acquisition, secondary transaction or public listing.

The basic structure is similar across markets. What changes dramatically is how each country treats those stages for tax and compliance purposes.

ESOP in Singapore

Singapore has one of the region's most developed frameworks for employee equity.

The Inland Revenue Authority of Singapore distinguishes between Employee Share Options and other forms of Employee Share Ownership.

For a normal stock option, the employee is generally taxed when the option is exercised. The taxable amount is usually the open-market value of the shares at exercise minus the price paid by the employee.

For share awards with a vesting period, taxation generally occurs when the shares vest. Selling restrictions can affect the timing.

For example:

• Exercise price: SGD 1 per share

• Market value when exercised: SGD 5

• Taxable employment gain: SGD 4 per share

Singapore also has important rules for foreign employees. When certain foreign employees leave Singapore with unexercised options or unvested awards, the "deemed exercise" rule may bring those gains into the tax-clearance process before the employee leaves.

This makes Singapore relatively predictable for ESOP planning but companies still need accurate valuations and proper employee reporting.

For a deeper explanation of local taxation, see the WOWS Global guide to ESOP taxation in Singapore.

ESOP in Thailand

Thailand also allows companies to use equity incentives but the tax treatment needs careful planning.

Under the Thai Revenue Code, employment income can include money, property or benefits received because of employment. The Revenue Department has specifically considered employee stock option arrangements in several rulings.

For options, simply receiving a future right to purchase shares does not necessarily create taxable income immediately.

The important event generally occurs when the employee exercises the option and obtains the shares. Thai Revenue Department rulings have treated the difference between the share value and the employee's exercise price as employment-related income.

The employer may also have withholding obligations when the benefit is treated as employment income.

This becomes more complex when a Thai employee receives options in a foreign parent company.

Startups should therefore consider the Thai tax treatment, company structure, valuation method and payroll process before promising equity to employees.

ESOP in Malaysia

Malaysia treats employee share scheme benefits as employment-related income.

Under guidance from the Inland Revenue Board of Malaysia, the taxable benefit is generally based on the lower of the market value when the option becomes exercisable or the market value when the employee actually exercises it then subtracting the amount paid for the shares.

The benefit is generally taxed in the year the option is exercised.

For example, suppose:

• Exercise price: MYR 2

• Market value when exercisable: MYR 7

• Market value when actually exercised: MYR 9

The relevant value under the rule would generally be MYR 7 because it is the lower value.

The employment benefit would therefore be MYR 5 per share before considering the employee's wider tax position.

Malaysia also has specific guidance for cross-border share plans. This makes documentation particularly important for companies whose employees move between jurisdictions.

ESOP in Indonesia

Indonesia is a market where companies need to be particularly careful about assuming that rules from Singapore or another regional headquarters will automatically apply.

Employment income can include non-cash benefits. Current tax guidance indicates that shares received by directors or employees or shares obtained through employee option schemes as compensation may be taxable as ordinary individual income.

The exact treatment can depend on how the award is designed.

Industry guidance notes that Indonesia does not have one simple standalone tax framework covering every type of employee equity award. Different approaches may apply to options, restricted shares and RSUs.

For startups, that means the plan should clearly define:

• what employees actually receive

• when rights vest

• when shares are acquired

• how the shares are valued

• whether the Indonesian employer has withholding obligations

A vague promise of "equity" is not enough.

ESOP in Vietnam

Vietnam deserves special attention because its ESOP tax framework changed significantly in 2026.

New regulations under Decree 253/2026 and Circular 87/2026 formally clarified the personal income tax treatment of bonus shares and ESOP shares.

Under the new framework, employees receiving certain ESOP shares do not necessarily pay employment tax immediately when the shares are received.

Instead, personal income tax can be triggered when the employee later transfers those shares. At that point there can be both employment-related tax treatment and tax relating to the securities transfer.

The regulations also introduce rules for determining the taxable value of ESOP shares and withholding responsibilities involving securities companies or custodian banks in relevant cases.

For regional startups, this is a useful reminder that ESOP tax rules do not stay static.

A plan created several years ago should not automatically be assumed to remain compliant today.

ESOP in the Philippines

The Philippines clarified the treatment of equity-based compensation through Revenue Regulations No. 13-2022.

Under the rules, equity-based compensation received by employees is generally treated as compensation when exercised or availed of.

Importantly, this treatment applies regardless of whether the employee is rank-and-file, supervisory or managerial.

That means the benefit can become part of the employee's compensation income and can also create withholding obligations for the employer.

Companies granting equity through an overseas parent should therefore make sure the local payroll team knows about the award. A common mistake with multinational option plans is keeping the entire process at headquarters while the local employer has tax reporting responsibilities.

ESOP in Hong Kong

Hong Kong also treats gains from employee share options as employment income for Salaries Tax purposes.

A share option gain generally becomes taxable when the employee exercises, assigns or releases the option.

The rule can continue to apply even if the employee exercises the option after leaving the employment that originally gave rise to the award.

For an exercised option, the taxable gain broadly reflects the value created between the acquisition cost and the value of the shares when the option is exercised.

Cross-border employees also require closer review because the location and source of employment can affect how much of a share option gain falls within Hong Kong Salaries Tax.

ESOP Asia Comparison

The biggest lesson from this table is simple: there is no universal ESOP Asia template.

What Regional Startups Should Do Before Granting Options

A regional startup does not necessarily need seven completely different ESOP plans.

It needs one well-designed global framework with local rules built around it.

Before granting options, founders should answer five questions.

1. Which company is issuing the options?

The parent company, local subsidiary and employing entity may be different companies.

2. What is the exercise price?

Startups need a defensible way of determining the value of their shares.

3. When does the employee become taxable?

Grant, vesting, exercise and sale can produce very different outcomes depending on the country.

4. Who handles withholding and reporting?

Do not assume employees are solely responsible for their own tax reporting.

5. What happens when someone leaves?

Good ESOP documents should clearly explain vested options, unvested options, exercise periods and what happens after termination.

ESOPs Are Powerful, but the Details Matter

Employee stock options can help startups compete for talent even when they cannot match the cash salaries offered by larger companies.

They can also create something more valuable: alignment.

Employees start thinking like owners because part of their potential reward depends on the long-term value of the business.

But equity compensation only works when employees understand what they have been given and companies understand the legal and tax consequences.

For startups operating across Asia, the best approach is not to copy an ESOP document from another company. Build a clear plan at group level then review taxation, valuation, reporting and administration country by country.
