⚠ 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.
Are you facing these tax issues?
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.
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.
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.
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.
