Retirement amount

Sir/mam, Plzz clear my doubt my father is retiring next month, he is an army officer.. He will be getting lumpsum amount of gratuity, pf etc so will it be taxable if I deposit that lumpsum amount in the bank account..?? And please tell me something as to how to keep that money so it will bear least tax... Aur if any tax is charged that how much would it be.. Thanku 😇
