⚠ Critical: Most MNC Employees Are Overpaying Stock Option Tax
Most multinational employers withhold salaries tax on 100% of the option/RSU gain — even when only a fraction of the vesting period was served in Hong Kong. Under DIPN 38, only the HK-sourced portion is taxable. If you were granted shares in the US and vested partly in HK, often 30-60% of the gain is simply not HK taxable. You can file amendments going back 6 assessment years to recover the excess.
주요 과제
Cross-Border Vesting Periods
Options granted in the US, vested partly in HK and partly in Singapore — determining the taxable portion in each jurisdiction requires precise day-count analysis under each country's rules.
⚠ Risk: No apportionment → full tax on gain that is only partially HK-sourced
Employer Withholding on Full Gain
Your employer's payroll withholds salaries tax on the entire grant value regardless of your actual HK service days. The excess is legally yours to reclaim — but only if you file the right forms.
⚠ Risk: Default withholding accepted → HKK-350K in unreclaimed overpayments
Unlisted Company Valuation
Pre-IPO option exercises require a defensible market value at exercise date. Using the wrong valuation method invites IRD challenge — too low risks additional assessment, too high means overpaying.
⚠ Risk: IRD default valuation → significantly overstated taxable gain
RSU vs Option — Different Taxable Dates
RSUs are taxable at vesting (share delivery), options at exercise. Getting the date wrong shifts you into a different assessment year, changing your effective rate and provisional tax.
⚠ Risk: Wrong taxable date → incorrect year assessment and provisional tax shock

자주 묻는 질문
When exactly is an RSU taxable in Hong Kong?
RSUs are subject to salaries tax at the point of vesting — the date restrictions lapse and shares are delivered. This is distinct from the grant date and the payment/settlement date. If there is a settlement lag, you use the vest date to determine taxable amount and assessment year. Each cliff-vesting tranche is a separate taxable event with its own vest date and apportionment calculation.
How does the DIPN 38 apportionment formula work?
The formula is: (HK Service Days / Total Grant-to-Vest Days) x Total Gain. HK Service Days are days during the grant-to-vest period you were rendering employment services in HK. Days overseas (including remote work while physically abroad) do not count. Weekends and holidays are included pro-rata. The formula applies separately to each grant/tranche — you cannot aggregate across grants.
My employer withheld tax on my full RSU gain. How do I get a refund?
File an amendment to your salaries tax return supported by employment location evidence for each vesting period. You have 6 years from the end of the relevant assessment year. IRD will review, may request documentation (passport, HR records, grant agreements), and issue a revised assessment. Refunds are typically processed within 60 days of the revised assessment.
What if my company is not listed? How is my option gain valued?
For unlisted companies, IRD's default is the most recent funding round price, which is frequently too high because it reflects preferred share pricing with liquidation preferences not available to option holders. An independent valuation using DCF, comparable multiples, or 409A-equivalent analysis — with documented marketability and illiquidity discounts — can establish a lower but defensible value.
Can I defer salaries tax on unexercised options?
Yes. Salaries tax only arises on exercise, not grant or vesting. You control when the tax event occurs by controlling when you exercise. However, most schemes impose 5-10 year expiry dates, and deferring concentrates tax burden in a single year. There is no HK equivalent of the UK EMI scheme or US 83(b) election — salaries tax is generally unavoidable at exercise.
