Gstr-3b

PCS Hardeep Singh Nijher (Practising Company Secretary)   (35 Points)

20 October 2017  
While, I am preparing my GSTR-3B return for the month of Sept. 2017, when I had prepared the ITC column by chance Purchase amount is entered in IGST cell whereas, I have not any purchase from out of state and hence not IGST for ITC. It is just come to know me, when I have just to go to file final return, as liability was not set off.
 
I have just Sale(within Punjab) of Rs. 71,200/- and CGST Rs. 6,407/- and Punjab SGST Rs. 6,407/- for sale @ 18% and whereas only Rs. 2,080/- purchase(within Punjab) for which ITC available for CGST Rs. 187/- and Punjab SGST Rs. 187/-.
 
Now, I have problem to file my GSTR-3B before due date, as it is not off set and even not revised.
Kindly, advice me accordingly.
