The clause was written for an all-resident cap table
Reverse vesting and buyback-on-exit clauses are contractual, not statutory, so nothing in the Companies Act stops founders from agreeing to buy back unvested shares at a nominal price. That's exactly why the clause clears legal review internally: it's genuinely fine, between two residents. FEMA only engages the moment either side of the transfer is a non-resident, and it doesn't ask what the founders' agreement calls the number, only what actually changed hands and in which direction.
Buying out a departing NRI founder cheap: no FEMA problem, but a real tax one
When the departing founder is the NRI and the buyer is a resident co-founder, FEMA's rule only sets a ceiling, the resident can't pay more than fair value, but there's no floor stopping them paying less. A nominal buyback clears that test easily.
The tax rules don't let it go that easily. Section 50CA deems the transfer to have happened at fair value regardless of what was actually paid, so the NRI still owes capital gains tax on a value they never received. Separately, Section 56(2)(x) taxes the resident buyer on the gap between what they paid and fair value, as income from other sources, once that gap crosses Rs 50,000. Both sides assumed a nominal price meant a quiet, low-tax exit. Neither gets that.
Run it the other way, and the price itself breaches FEMA
If it's a resident founder leaving and the buyers are the NRI co-founders, the same nominal price now fails the floor test directly, a resident-to-non-resident transfer has to be priced at not less than fair value. This isn't a tax surprise anymore, it's a FEMA contravention on the transfer itself, the kind that needs RBI compounding to fix after the fact.
A guaranteed-return exit clause fails for a different reason, in either direction it's drafted. If it promises an NRI shareholder a fixed price or minimum IRR on a future exit, RBI's optionality rules don't allow it: the only exit price a non-resident's option can specify is the fair value determined when it's actually exercised, with at least a 1-year lock-in first. The clause isn't just risky, it's unenforceable as written.
