A. Pls note that DEEPA TRADERS VERSUS PRINCIPAL CHIEF COMMISSIONER OF GST & CENTRAL EXCISE CHENNAI, TAMIL NADU, SUPERINTENDENT OF GST, CENTRAL EXCISE, COIMBATORE GOODS AND SERVICES TAX NETWORK (GSTN) , NEW DELHI 2023 (3) TMI 628 - MADRAS HIGH COURTis on totally different facts as the error was made in reporting outward supply as seen from Para 2 of the decision:
A.1. The petitioner has, in respect of the returns for a few months during the period 2017-18, admittedly, committed certain errors. The errors are of following nature.
i) Recipients GSTIN/name has been wrongly mentioned.
ii) The invoice number/date have been wrongly mentioned.
iii) Supply details were correctly supplied in GSTR 3 and tax duly remitted. However, some of the invoice wise details have been omitted to be reported in Form GSTR 1.
iv) IGST was inadvertantly remitted under the heads SGST and CGST.
A.2 Therefore the courts have permitted the petitioner's GSTR-1 to be modified to correct the outward tax declared therein.
A.3 The Querist's case however is ITC wrongly availed in GSTR-3B. It is not with regard to output tax declared by him in GSTR-1 and so, there is no requirement of amending GSTR-1 here at all. Therefore, the judgement referred above may not be of any direct application here.
B. Pls note that there is also one more very recent decision of Madras High Court in Kondamma Trading vs The Assistant Commissioner of CGST & Central Excise -2023 (10) TMI 794 - MADRAS HIGH COURT (see https://mhc.tn.gov.in/judis/index.php/casestatus/viewpdf/1077164), wherein, in the identical issue as yours, the Court has directed the petitioner to file a rectification application u/s 161.
B.2. However, in this case revenue had erroneously submitted before the Court that section 161 is invocable whereas as per provisions of section 161, it cannot be invoked in case of returns filed by TP. Therefore, with due respect to the decision, it may not be correct in law.
B.3. Nevertheless, in my opinion, these decisions do not provide any immediate practical solution to tax payer for the reason that GSTN portal is not designed in such a way as to allow amendment/modification to GSTR-3B once filed. Therefore, it would require technical changes in GSTN level.
