Hong Kong Tax Treatment of Share Options and Share Awards for Employees

Hong Kong Tax on Share Options and Share Awards

Share options and share awards are common tools for Hong Kong companies to attract and retain employees. Tax arises on exercise or vesting, not on grant. The valuation method depends on whether the shares are listed or unlisted, and the jurisdiction where the employee performs duties can affect whether the income is subject to Hong Kong salaries tax at all.

When Is an Option or Award Taxable: Exercise or Vesting, Not Grant

No salaries tax liability arises when an employer grants an option or award. Tax is deferred until the employee exercises the option (for share options) or the award vests (for share awards). At that point, the employee receives a benefit subject to salaries tax under the Inland Revenue Ordinance (Cap. 112).

For share options, the taxable event is exercise. For share awards, the taxable event is vesting, when the employee becomes entitled to the shares. If the shares are listed, the market value at exercise or vesting is readily ascertainable. If unlisted, the value must be determined by reference to a valuation performed by the employer or an independent valuer.

Valuation of Share Options and Awards for Salaries Tax Purposes

The taxable value is the difference between the market value of the shares at the date of exercise or vesting and the exercise price paid by the employee. If the employee pays no exercise price, a nil-cost option, the full market value of the shares at exercise or vesting is assessable.

For listed shares, the IRD accepts the closing price on the exercise or vesting date as the market value. Intra-day fluctuations are ignored. For unlisted shares, the employer must obtain a valuation that reflects the fair market value of the shares at the relevant date. The valuation should consider factors such as the company's net asset value, earnings, and liquidity discounts. The IRD may challenge the valuation if it appears too low.

Employer Reporting Obligations: IR56B and Related Forms

Employers must report share option and share award benefits as part of their annual employer's return. The key form is Form BIR56A, the annual employer's return covering all employees. For each employee who exercised a share option or received a vested share award during the year of assessment, the employer must complete Form IR56B. The value of the benefit, the market value less any exercise price, is entered in the relevant box on Form IR56B.

The employer must also notify the IRD of certain events:

• Form IR56E: notify the IRD within three months of employing a new employee who is eligible for share options or awards.
• Form IR56F: notify the IRD at least one month before an employee ceases employment.
• Form IR56G: notify the IRD at least one month before an employee leaves Hong Kong (for example, to take up an overseas posting).

Failure to file these forms on time can result in penalties. The IRD cross-checks employer returns against employee returns to ensure benefits are declared.

Employee Disclosure on BIR60

Employees must report share option and share award benefits on their individual tax return, Form BIR60. The benefit is included in the "Salaries and allowances" section of the return. The employee should enter the value as stated in the employer's Form IR56B, which is provided to the employee as a copy at year-end.

If the employee performed duties partly outside Hong Kong, an offshore claim may be available to reduce or eliminate the tax. The basis for an offshore claim is the territorial source principle: only income arising in or derived from Hong Kong is chargeable to salaries tax. An employee who exercised options or received vested awards while working outside Hong Kong may argue that a proportion of the benefit is not subject to Hong Kong tax. The IRD applies the time apportionment method described in Departmental Interpretation and Practice Note 10. The employee must provide evidence of the days worked outside Hong Kong and the days worked in Hong Kong during the basis period.

Unlisted Shares: Special Valuation Considerations

For unlisted shares, the valuation approach is critical. The IRD does not prescribe a single valuation method but expects a reasonable and supportable value. Common methods include:

• Net asset value method: appropriate for holding companies or property-rich companies.
• Discounted cash flow method: appropriate for high-growth companies.
• Comparable company analysis: appropriate where listed peers exist.

The employer bears the risk of undervaluation. If the IRD later determines that the shares were undervalued, it may issue an assessment based on its own valuation, and the employee may face additional tax and penalties. To reduce this risk, many employers obtain an independent valuation and retain supporting documentation.

Offshore Claims for Share Options and Awards

An offshore claim is a challenge to the IRD's assertion that the benefit arises in Hong Kong. The claim is available where the employee performed the duties giving rise to the benefit outside Hong Kong. For share options, the IRD considers the benefit to arise when and where the employee exercised the option. If the employee exercised the option while physically outside Hong Kong, the benefit may be sourced entirely offshore. For share awards, the benefit arises upon vesting, and the location of the employee at that time is relevant.

The IRD's practice note DIPN 21 addresses the locality of employment income, including share-based benefits. The note states that the benefit is sourced where the employee performed the duties that were rewarded by the option or award. This can be complex where the employee worked in multiple jurisdictions during the vesting period. The IRD will apportion the benefit based on the number of days worked in Hong Kong versus outside Hong Kong during the period from grant to exercise or vesting.

Year of Assessment and Basis Period

The taxable year of assessment is the year in which the exercise or vesting occurs, not the year of grant. If an option is granted in 2023 but exercised in 2025, the benefit is assessable in the year of assessment 2025-26. The basis period is the calendar year ending 31 March. The employer's return (Form BIR56A and Forms IR56B) for that basis period must include the benefit.

Provisional Tax and Holdover

Provisional tax is payable for a year of assessment before the actual return is filed. If an employee exercises share options or receives vested awards in a year, the provisional tax for the following year will be based on that year's income. If the employee expects a lower benefit in the next year, they may apply for a holdover of provisional tax on the grounds that the assessable profits will be less than 90% of the provisional tax charge. The application is made on the tax return or by separate letter to the IRD.

Summary of Key Forms

Final Point on Compliance

Hong Kong share options and share awards must be reported accurately and on time. Employers should maintain a clear record of each grant, exercise, and vesting event. Employees should review their Form IR56B each year and ensure the values match their own records. If an offshore claim is intended, detailed travel records are essential. The IRD actively cross-checks employer and employee returns for share-based benefits, and discrepancies can trigger an investigation.
