Verify tax paid data with form 26AS
It is important to verify the TDS details and the advance tax paid details in Form 26AS. There could be a possibility wherein, your bank / employer had deducted your TDS but it is not credited to your PAN due to some technical errors. It could be an error by oversight or by mistake that the deductor had not quoted your PAN correctly in his TDS return. Also, there is a chance that we forget to mention some FD interest in our return, which would be verified with 26AS.

Documents to be submitted
Also we should not forget to attach ITR V with physical return. Chances of missing ITR V in physical return are less, as IT Dept would not accept your physical form without ITR V.
But if we are e-filing n digital signature, we should not forget to send the signed ITR V to CPC Bangalore. If our ITR V does not reach CPC Bangalore within 120 days of e-filing your return, then our return is not considered to be complete.
