No Mandatory ITC Reversal on Post-Sale Discounts by the Buyer, if GST liability paid by raising Debit Note

The Hon’ble Gujarat High Court in the case of Shree Ambica Auto Sales and Service & Anr. v. Union of India & Anr. [R/Special Civil Application No. 1277 of 2024, order dated January 8, 2026] held that there is no statutory provision mandatorily requiring the buyer to reduce input tax credit on the basis of credit notes issued by the seller, and directed re-opening of GST portal for rectification of GSTR-1 and GSTR-3B despite due date expiry where revenue neutral.

Facts:

Shree Ambica Auto Sales and Service & Anr. (“the Petitioners”) are dealers of Tata Motors vehicles who availed ITC on vendor invoices, issued debit notes on receiving post-sale discount credit notes from vendor, discharged output tax thereon via GSTR-1/GSTR-3B, but faced ITC mismatch due to wrong column reporting of debit notes in GSTR-1.

​Union of India & Anr. (“the Respondents”) coerced reversal of Rs.10,99,06,850/- ITC via DRC-03 during inspection, issued SCN dated October 06, 2023 proposing Rs.34,26,33,614/- ITC reversal against Rs.42,75,68,473/- tax already paid, and passed order dated December 26, 2023 refusing appropriation.

​The Petitioners’ contention was that impugned order dated December 26, 2023 is without jurisdiction as tax paid exceeded proposed reversal and that the vendor bears disallowance risk under Section 15(3)(b) if buyer does not reverse ITC per Section 43. Therefore, no mandatory reversal exists at the buyer’s end, and they seek rectification of GSTR-1 for the impugned period.

The Respondent did not dispute no revenue loss if rectification permitted, but denied appropriation confirming demand requiring refund claim on debit note tax. The Petitioners’ grievance was that the payment was coerced, despite revenue neutrality and that denial of rectification causing prejudice despite no tax liability, hence approaching via R/Special Civil Application No.1277/2024 and 783/2021 before this court.

Issue:

Whether the buyer is mandatorily required to reverse ITC on post-sale discount credit notes issued by seller, and whether rectification/amendment of GSTR-1/GSTR-3B is permissible beyond due date in revenue neutral mismatch cases due to portal reporting error?

Held:

The Hon’ble Gujarat High Court in R/Special Civil Application No. 1277 of 2024 held as under:

  • Observed that, the Petitioners claimed ITC on vendor invoices, issued debit notes on credit notes for discounts, admitted output tax liability thereon in GSTR-1/GSTR-3B, effectively reducing ITC.
  • ​Noted that, GST portal matching considers only buyer-reported credit notes received, ignores buyer-issued debit notes despite tax paid thereon reducing ITC, causing GSTR-2A mismatch from wrong GSTR-1 column reporting.
  • ​Held that, no difference in actual tax liability even assuming authorities’ stand, tax paid Rs.42,75,68,473/- exceeds proposed reversal Rs.34,26,33,614/- and is a revenue neutral situation.
  • ​Observed that, there is no statutory provision under the GST Acts mandatorily requiring the buyer to reduce input tax credit on the basis of credit notes issued by the seller and that the vendor liable under Section 15(3)(b) if buyer does not reverse.
  • Held that, provisions of Section 37(3) read with Sections 38, 39(9), 39(10) require purposive interpretation allowing bona fide inadvertent rectification despite portal limits/provisos where no revenue loss, as GST electronic regime accommodates human errors without illegal gain.
  • ​Quashed order passed by the Respondents dated December 26, 2023 and directed respondents to open GST portal within four weeks for Petitioners to amend/rectify GSTR-1/GSTR-3B within ten days or accept manual application if portal not opened, with consequential relief.

Our Comments:

The judgment relies on Bombay HC in Star Engineers I Pvt. Ltd. v. Union of India [Writ Petition No.15368 of 2023, dated December 14, 2023], directing amendment/rectification of GSTR-1 beyond due date via portal/manual where inadvertent reporting error caused mismatch but no revenue loss and purposively interpreting Section 37(3) r/w 39(9) beyond provisos for bona fide errors in electronic GST regime.
