Dear Sir: I have received notification under section 143(1) stating there is a mismatch of what is reported in the IT return and Form 26 AS with respect interest earned frm FD. However I have checked the Form 26AS as on 5th Sep 2018 and found no mismatch between what I entered in the Return with what is on 26AS. Even the TAN no matches perfectly. I only see that the "date of booking" on the form 26AS for the Deposit is "June 2018". I don't think this is the reason because it is included in the form 26AS of the Assessment year 2018-19. Also I checked the last year form 26AS and found that "booking date" from the same company was "june 2017" and I did not receive any notification of mismatch for last year.
So I don't know what to do since 26AS and my return shows the same data but Income tax is refusing to provide refund.
Also there is no way to file rectification as option AY2018 is not available in the IT website.
