Under the proposed scheme, a person or entity would be allowed to deposit a minimum quantity of 30 grams of gold in any form, bullion or jewellery, for one year in a gold saving account. The banks will decide the interest rate. To make the scheme attractive to households, the interest earned on it will likely be exempt from income tax, wealth tax and capital gains tax. Before depositing gold into a metal account, customers will have to get its purity checked from the testing and collection centres certified by the Bureau of Indian Standards (BIS). They will be given a certificate by the collection centre certifying the amount and purity of the deposited gold.
