The situation
The client was a Singapore-incorporated B2B software firm. The founders had launched in Singapore, expanded into two ASEAN markets and Hong Kong over three years, and were preparing a Series B financing round.
Their ESOP, drafted at Series A by a US-template-leaning lawyer, treated all option grants identically regardless of recipient location. By the time we engaged, employees and contractors in four jurisdictions held grants on the same plan. Several had relocated mid-vest from one jurisdiction to another.
The Series B lead investor's diligence flagged the cross-border ESOP as a material risk. Specifically: which jurisdiction's tax law applied to vesting, when withholding obligations crystallised, and whether the Singapore parent had under-reported any of these to IRAS over the prior two reporting periods.
What we did
Step 1
Mapped the actual grant population and tax-residence history
We started by reconstructing each grantee's tax residence at grant date, vesting dates, and exercise dates over the past three years. The plan administrator had records of grants and vesting but not of tax residency at each event. We worked with the firm's HR data and (where available) personal tax filings to build a per-grantee per-event grid.
Step 2
Identified the four-jurisdiction tax compliance gaps
For each grantee, we mapped the tax treatment that should have applied at vest and exercise across Singapore, the two ASEAN jurisdictions, and Hong Kong. Two grantees had vested while changing tax residency mid-year — neither had been correctly characterised. Three relocated grantees had triggered withholding events at the parent level that had not been remitted to IRAS as required.
Step 3
Restructured the plan into a residence-aware framework
We worked with local tax counsel in each jurisdiction (briefed by us) to redraft the plan administration to handle residence changes correctly going forward. The plan vesting mechanic stayed the same; the administrative documentation, the tax characterisation of each event, and the withholding pathway were rebuilt.
Step 4
Prepared corrective filings before Series B closing
For the historical compliance gaps, we coordinated voluntary disclosure with IRAS for the three under-reported events, settled the resulting tax and interest, and obtained closure letters before the Series B due diligence round.
Outcome
The Series B closed on schedule. The previously flagged ESOP issue was resolved on the diligence side via the corrective filings, the residence-aware administration redesign, and the closure letters from IRAS. The lead investor's tax counsel signed off on the cleaned-up plan as condition-precedent satisfied.
In post-close documentation, the firm's effective tax position improved by avoiding penalty exposure on the historical events. Going forward, the residence-aware administration produces correct withholding outcomes within roughly five-business-day documentation cycles per relocation event, versus the previous ad-hoc approach.
What this case illustrates
Three patterns we see repeated across cross-border ESOP situations.
First, US-template-leaning ESOP plans imported into Singapore-headquartered SME contexts often do not handle vest-during-relocation cleanly, because the original drafter assumed all grantees would stay in one tax residence.
Second, the cost of corrective filings grows non-linearly with time. Two reporting periods of under-reporting was correctable through voluntary disclosure with manageable economic cost. Five reporting periods would have been materially more expensive and exposed the founders personally on certifications they had signed.
Third, financing round diligence is the most common surface where ESOP cross-border issues are first flagged. Founders we advise typically prefer to address these before the diligence round opens rather than during it; the timeline pressure of "fix this in two weeks before signing" rarely produces the cleanest outcome.
