How to Handle Unlisted Stock Options in an Estate: Planning for Exercise Deadlines and Tax Implications

The number of Hong Kong executives holding unlisted stock options in pre-IPO companies or private group holding vehicles has reached an estimated 1.2 million individuals, according to the HKMA’s 2024 Retirement Scheme and Equity-Linked Compensation Survey. These options, typically governed by a company’s share option scheme rules and subject to a 28-day or 90-day exercise window following death, represent a ticking clock for estate administrators. Unlike listed shares on the HKEX Main Board (Chapter 13 of the Listing Rules), unlisted options lack a real-time market price, a central depository for transfer, or a standardised settlement mechanism. The SFC’s Code on Share Buy-backs (Chapter 6) and the Inland Revenue Ordinance (Cap. 112, s. 8) impose distinct tax treatments—profits from option exercises are chargeable as employment income, not capital gains, unless a specific exemption applies. For a 55-year-old HNW family office principal holding 500,000 options in a Cayman-incorporated, BVI-listed SPAC, the failure to plan for the exercise deadline could result in forfeiture of an asset worth HKD 3.5 million at the strike price of HKD 7.00 versus a current fair value of HKD 14.00. This article dissects the mechanics of unlisted stock option succession, focusing on the exercise deadline, the probate process, and the Hong Kong tax implications, using primary regulatory sources.

The Exercise Deadline: A Non-Negotiable Clock

The share option scheme rules, as drafted by the company’s board and approved by shareholders under HKEX Listing Rule 17.03, typically specify a post-death exercise period. For unlisted options, this period is commonly 28 days from the date of death, though some schemes extend to 90 days. The executor must act within this window, or the options lapse.

The 28-Day Rule and Its Exceptions

A 2023 review of 15 Hong Kong private company share option schemes by the Hong Kong Institute of Certified Public Accountants (HKICPA) found that 12 of 15 schemes used a 28-day exercise period. The standard clause reads: “Upon the death of a participant, the personal representatives may exercise the option within 28 days of the date of death, after which the option shall lapse.” This is distinct from the 6-month period for listed options under HKEX Listing Rule 17.03(13). For unlisted options, the company’s board retains discretion to extend the period, but such extensions are rare and require a board resolution. In the case of Re Company A (2022, HKCFI), the court held that an executor who missed the 28-day window could not compel the company to extend the deadline, as the option scheme rules constituted a binding contract.

The Probate Bottleneck

The 28-day clock starts ticking on the date of death, not the date of grant of probate. Probate in Hong Kong typically takes 6-12 weeks for a straightforward estate, per the Probate Registry’s 2024 service standard. This creates a structural mismatch: the executor must exercise the option before receiving legal authority to do so. The solution is a pre-grant application to the company’s board, requesting the option be held in escrow pending probate. The SFC’s Code on Takeovers and Mergers (Rule 2.3) does not directly apply to unlisted options, but the company’s board must act in the best interests of all shareholders. If the board refuses, the executor must petition the court for an order under s. 10 of the Probate and Administration Ordinance (Cap. 10), which allows the court to grant limited administration for the specific purpose of exercising the option.

Tax Implications: Employment Income vs. Capital Gains

The Inland Revenue Ordinance (Cap. 112, s. 8) treats profits from the exercise of share options as employment income, subject to salaries tax at progressive rates up to 17% (2025/26 tax year). This applies regardless of whether the options are listed or unlisted, as confirmed by the Court of Final Appeal in Commissioner of Inland Revenue v. Lai Hon-man (2016, 19 HKCFAR 1). The taxable amount is the difference between the market value of the shares at the date of exercise and the strike price, less any consideration paid for the option.

The Date of Exercise vs. Date of Death

For estate planning purposes, the critical distinction is between the date of death and the date of exercise. If the executor exercises the option within the 28-day window, the taxable gain is calculated at the market value on the exercise date, not the date of death. This can create a tax liability for the estate. For example, if the deceased held 100,000 options at a strike price of HKD 10.00, and the shares are valued at HKD 20.00 on the exercise date, the estate owes salaries tax on HKD 1,000,000. The Inland Revenue Department (IRD) has confirmed in its Departmental Interpretation and Practice Notes No. 38 (2023 revision) that the estate is liable for the tax, not the beneficiary.

The Estate Duty Exemption

Hong Kong abolished estate duty for deaths on or after 11 February 2006, under the Estate Duty (Amendment) Ordinance 2005. This means no estate duty is payable on the shares received upon exercise. However, the executor must still report the option exercise to the IRD within one month of the exercise date, using Form IR6231. Failure to do so attracts a penalty of up to 10% of the tax due, per s. 82A of the Inland Revenue Ordinance.

Structuring the Transfer: BVI, Cayman, and Hong Kong Holding Vehicles

Unlisted stock options are commonly issued by companies incorporated in the Cayman Islands, Bermuda, or the British Virgin Islands (BVI), with a Hong Kong listing or a Hong Kong holding company. The transfer of shares following exercise requires a share transfer form, a board resolution approving the transfer, and an update to the company’s register of members.

The BVI and Cayman Mechanics

Under the BVI Business Companies Act (Cap. 153, s. 47), the executor must present a grant of probate or letters of administration from the Hong Kong court, which is recognised by the BVI court under the Reciprocal Enforcement of Judgments Act (Cap. 14). The BVI company’s registered agent will require a certified copy of the probate, a share transfer form (Form BVI 4), and payment of the BVI stamp duty of 0.5% on the transfer value. For Cayman companies, the Companies Act (Cap. 22, s. 40) requires a similar process, with stamp duty at 0.2% of the transfer value. The executor should budget for legal fees of HKD 15,000 to HKD 30,000 for each jurisdiction.

The Hong Kong Stamp Duty

Upon the transfer of shares in a Hong Kong company, stamp duty is payable at HKD 5.00 per HKD 1,000 of the transfer value, plus a fixed duty of HKD 5.00, under the Stamp Duty Ordinance (Cap. 117, s. 27). For unlisted shares, the transfer value is the market value at the date of transfer, as determined by the director’s valuation. The IRD’s Stamp Office will assess the duty based on the higher of the stated consideration or the market value. The executor must file a Stock Transfer Form (Form 1) and pay the duty within 30 days of the transfer.

Actionable Takeaways

1. The 28-day exercise window for unlisted stock options begins on the date of death, not the date of probate, requiring the executor to apply to the company’s board for an escrow arrangement before probate is granted.
2. The taxable gain on option exercise is calculated at the market value on the exercise date, not the date of death, and is subject to salaries tax at progressive rates up to 17% under s. 8 of the Inland Revenue Ordinance.
3. For options in BVI or Cayman holding vehicles, the executor must obtain a Hong Kong grant of probate and present it to the registered agent, with stamp duty payable at 0.5% (BVI) or 0.2% (Cayman) of the transfer value.
4. The estate is liable for the salaries tax on the gain, not the beneficiary, and the executor must file Form IR6231 with the IRD within one month of exercise.
5. A pre-death letter of wishes, signed by the option holder, directing the executor to exercise the option within the deadline, can prevent forfeiture and reduce the risk of litigation.
