As far as I am concerned I am a taxpayer from almost the last 30 years and I am submitting my returns every year. So to give all the particulars there is no necessity to hide any information I think. Similarly, my two sons and my wife are also submitting their returns and there is no hiding the facts.
I hope many people will also do the same thing. We have to see how politicians and some government employees will reflect on this type of surveys.
