My Father had done some transaction during my marriage. He has depositted the amount and withdrow whenever necessary. So this transaction amounted to Rs. 13 Lakhs. He is normally a non-tax payer. He is dependent of me. He has received a notice from the IT dept to pay tax for the same amount. This 13 Lakhs also includes the amount (4 Lakhs) that my father-in-law has gifted me for my marriage. What can I do to solve this issue. Please help
