33. Section 16(4) of CGST Act : A registered person shall not be entitled to take input tax credit in respect of any invoice or debit note for supply of goods or services or both after the due date of furnishing of the return under section 39 for the month of September following the end of financial year to which such invoice or invoice relating to such debit note pertains or furnishing of the relevant annual return, whichever is earlier :
SECTION 39. Furnishing of returns. - [(1) Every registered person, other than an Input Service Distributor or a non-resident taxable person or a person paying tax under the provisions of section 10 or section 51 or section 52 shall, for every calendar month or part thereof, furnish, a return, electronically, of inward and outward supplies of goods or services or both, input tax credit availed, tax payable, tax paid and such other particulars, in such form and manner, and within such time, as may be prescribed;
A combined reading of both reveals that Section 16(4) talks of due date of furnishing return under Section 39 and Section 39 (1) talks of a return every month. It is monthly return GSTR 3B which is the basis of notice and not annual return. Annual return is under Section 44 and still no provision in Common Portal for 18-19 has been made so for . Due date of furnishing annual return for 18-19 cannot be the basis of notice issued for the year 18-19. GSTR 3 return has been omitted and return GSTR 3B which was converted into return from statement retrospectively w.e.f. 1.7.17 is the basis.
So retrospective amendment should be challenged by those who have been issued notices for denial of ITC under Section 16(4) of CGST Act, it being time barred.
As per dictionary meaning of word 'A' is 'ANY' . 'a return' means any return under Section 39 and not under Section 37 and Section 38 . GSTR 3 B is only monthly GSTR 2 & 3 both are not in picture. GSTR-1 is monthly as well as quarterly.
