I filled tds return of 24Q Q_4 FY 15-16, in which I quoted 4 challans correctly. CPC raised demand against an unmatched challan after return processed. When I gone through justification report I found the challan details were totally correct which I feeded in tds return, the confirmation now has been very strong when I cross verified unmatched challan on Oltas. I have few points which I want to know.
1) Why CPC has given demand for unmatched challan, when in that case challan details was totally correct in tds filling return.
2) I went for online correction through traces & tried to tag challan. I found there were the option of two financial years 15-16 & 14-15, but in both the years, the unmatched challans were not showing. Why?
3) When I traced unmatched amount of challan through CIN. I found it is matched but challan's year is changed from FY 15-16 to FY 13-14. And challan is in my hand, FY 15-16 is printed here.. In that case can mistakes be done through Bank?
Please advice me for above issues.
