My father have made LTCG gain in FY 2020-21 by selling of Stocks. He has purchased those stocks in several years in small quantities. My question is how to provide script wise detail in ITR .
Can we use the average cost of each stock as Cost of acquistion and date of last purchase as date of purchase ? Will Income tax deptt verify the purchase cost with actual price of stock on that date ?
For Eg, he has purchased 100 shares of Reliance with last purchase of 10 shares in Jan 2019 , and sold all Hundred in Feb 2021 . Can I declare purchase date of all 100 shares as Jan 2019 and use average cost of 100 shares for LTCG calculation ?
