I am a resident senior citizen income tax payer having income only from pension and bank interest. I have completely paid tax for FY2015-16 /AY2016-17 by way of advance tax, self-assessment tax and TDS, but may not be able to e-file ITR-1 by 31.07.2016 for some unavoidable reasons. However, I am hopeful to file it in the first week of August 2016. What are the consequences under Income Tax Act for this delay? Am I required to pay any penalty or fine?
