Frequently asked questions
What is grandfathering in LTCG?
Grandfathering is a provision introduced in Budget 2018 to grandfather (protect) pre-existing equity gains. For equity shares/MFs bought before Feb 1, 2018, the cost of acquisition is stepped up to the Fair Market Value (FMV) as on January 31, 2018 — so any gains accumulated before that date are tax-free. Only gains after Jan 31, 2018 are taxable at 12.5% (above ₹1.25L exemption).
Where do I find the Jan 31, 2018 NAV for mutual funds?
For mutual funds, the Jan 31, 2018 NAV is available on AMFI website (amfiindia.com) under historical NAV. For listed equity shares, the FMV is the highest traded price on NSE/BSE on Jan 31, 2018 (or the last trading day if Jan 31 was a holiday). Your broker or demat account statement should also show the grandfathered cost.
