Which one of the following proposals is incorrect about change in the salary earners as per the Union Budget 2011-2012?

Salary earners having an income of less than Rs. 5 lakh will not have to file tax returns.

The exemption from filing tax returns come into effect from the assessment year 2012-13.

In case such a salary earner has income from other sources like dividend, interest etc. and does not want to file returns, he will have to disclose such income to his employer for tax deduction.

The Form 16 issued to salaried employees will be treated as Income Tax Return.
