The Income Tax Department may send notice to the violator now as days in case of slight violation as these institutions allow cash transaction to a certain limit. Here are top 5 cash transactions that can attract income tax notice -Bank FD (fixed deposit): Cash deposit in bank FD is allowed but it should not go beyond Rs 10 lakh.
