The headline 'tax-free GIFT City' is a half-truth that confuses two distinct things: the taxation of the fund vehicle itself, and the taxation of the investor who holds units in it. Getting offshore investors comfortable means separating the two cleanly.
At the entity level, IFSC fund managers and certain fund vehicles enjoy a tax holiday on business income for a defined window, alongside exemptions from securities transaction tax, commodities transaction tax, and stamp duty on transactions executed on IFSC exchanges. This reduces the leakage that would otherwise drag on fund-level returns.
