Dear All,
I have filled my It return in FY 14-15, My income was non taxable as per the IT rates prevailing that time. In the mean time I have not considered an income amounts to Rs 30,000/- bcz I have not received the same. Till now also I have not got that money. Now I have got notice from IT department U/s 148. Should I file revise return for that period including that income. If I include that income again than also my income will be non taxable. what should I do please guide me.
Thanks and Regards,
Sanjay.
