For the FY 2014-15 my income was Rs. 2 Lakhs but I have wrongly entered it as Rs. 20 Lakhs in my ITR 4. After submitting my return online and e-verifying, I noticed this mistake. I had filed my return on 31 July 2016 as belated return. Today I got intimation for income tax department u/s143(1) and demanding tax of Rs. 6 Lakh. Please guide me in detail how to make rectification u/s 154. which all option under the heading ‘Taxpayer is correcting the Data in Rectification’ is to be selected as it allows to select only 4 options. My income is from business and profession and no other income or deduction.
