2) Not Including Interest

In budget 2012, a new section was introduced called Section 80TTA. The section offers deduction up to 10, 000 in the total interest that you have earned through your savings bank account. Moreover, this tax deduction does not include interests that you have earned on bank deposits. The interests that you have got on fixed deposits and recurring deposits will remain unchanged. 

While filing your tax returns you should mention these things under the sub head named 'Income from other sources'.

3) Not Inspecting TDS Details

Before you go and file your income tax returns, make sure that the tax return you have filed in the previous year is properly credited in your name. Form 26AS helps you with complete details of the tax deductibles that you can avail before filing the current year tax returns. You can even check it through online. Your job will become easier if you have a ‘Net Banking’ account with any of the 35 banks that offers these special facilities.

Otherwise, there is another option that is through the official website of the Income Tax Department. You can directly go to the site, register yourself and click on 'View your tax credit'.
