ok... thanks. But while filling GSTR1 and 2 for those earlier months what shall I do? should I claim that ITC in those months GSTR1 and 2 ? what if I haven't done that in previous month's return?
As per provisions of GST, you can avail inpit credit on purchase of goods or services within six months from end of FY. Hence you can show such purchases in GSTR-2 of month in which you claimed in GSTR-3B
