Nobody ll ask you for any thing. Income proof is a pre requisite to open an account and once its opened then the bank as an institute doesn't have to do anything with it unless yours or your dad name is sent by state bank for any kind of investigation incase of involvement in laundering, scammed money, relation to any banned out fit etc which I am pretty sure wouldn't be the case. All the taxes are subjected to the predefined clauses undersigned by you at the time of account opening. Bank is liable to compensate incase even if a penny is deducted from your account without any instrument having been signed by you. Having said this pls note that bank is permitted to deduct the service charges as per policies such as minimum balance, cheque book leaves charges, pay order, demand draft and the nastiest of all, 0.3% on the cash withdrawl if exceeded from the limit which is 25k to the best of my knowledge.
Hope it answers your query.
