Hey @Tanmay_mehta,
In Budget 2018, the grandfathering rule was announced u/s 112A which implies that - long term capital gains above INR 1 Lakh will be taxed at 10% after 1st Feb 2018.
Therefore to calculate LTCG:
- Take the equity value as on 31st Jan 2018 to be X
- so LTCG = Sales price - value as on 31st Jan 2018
- LTCG = 1,80,000 - X
Any tax on LTCG will be 10% above INR 1 Lakh
- LTCG below INR 1 Lakh is fully exempt
- LTCG above INR 1 Lakh will be taxable at 10% for the amount above INR 1 Lakh only.
Hope this helps!
