Demand u/s 143(1)- how to go about it?

Check who has deducted that TDS of Rs. 6000/- which is not reflecting in 26AS. Ask them to look at their TDS return status. Did you receive TDS certificate of Rs. 6000/-? 

Follow up the deductor to revise the TDs return or file a correction statement.

Thanks,

Thank you all.

The deductor is the employer and the Form 16 shows the total deduction to be Rs.29,000. Its only the 26AS which is showing Rs.23,000.

So from what I understand from you replies is that the assessee doesn't have to do anything right? He should inform his employer and ask him to check and revise his TDS return?

Yes, Rajat.Your observation is correct.

Thanks

Are u sure Form 16 shows 29000 as deduction?

As process for form 16 has been revised now, u get Form 16 part A from TRACES will shall match with 26 AS of employer..the chances of mismatch are slim..

@ Dipjyoti Majumdar- Thanks

@ Akshata- Yes its Rs.23,000. The Form16 is for AY 2012-13 and is hand written. The employer is a Govt. Hospitalin Kolkata.
