Tds challan no.00002, bsr code. 0291585 dt 01/07/2007 for rs.2000 has paid wrongly for the assessment year 2017-18 instead of assessment year 2018-19, it was our mistake to fill up properly on the challan no/ itns 281.
Now its needed to rectify the challan and transfer to the assessment 2018-19 of the said challan, but they desperately deny to do the same.
Why they are not agree to do this.
Please inform us if you have no option or any provision to rectify the challan immediately
