Pass on of Tax Rate Reduction must reduce prices; failure found, profiteering confirmed and interest levied prospectively.

Rule 133 timelines are directory and do not bar proceedings; therefore the investigation proceeded. The supplier raised base prices concurrent with a GST rate reduction and failed to rebut the rebuttable presumption that rate decreases must be passed to recipients, so profiteering is established and the recomputed profiteered amount is accepted. Interest may be levied only prospectively from the notified effective date for interest and is payable on the profiteered amount until deposit. Penalty provision introduced later cannot be applied retrospectively to the investigation period. Half of recovered sums are directed to designated consumer welfare funds.

Issues: (i) Whether the proceedings are barred by limitation and whether the time limit in Rule 133 of the Central Goods and Services Tax Rules, 2017 is directory or mandatory; (ii) Whether the Respondent indulged in profiteering by failing to pass on the benefit of GST rate reduction from 18% to 5% w.e.f. 15.11.2017; (iii) Whether interest and penalty can be imposed on the Respondent for the period of violation.

Issue (i): Whether the time limit under Rule 133 of the Central Goods and Services Tax Rules, 2017 is directory or mandatory and whether the proceedings are barred by limitation.

Analysis: The Tribunal examined precedent including P. T. Rajan v. T.P.M. Sahir and relevant High Court decisions which treat statutory timelines for administrative action as directory where no consequence for non-adherence is prescribed. The anti-profiteering provisions were noted to be beneficial in nature aimed at consumer protection, and Rule 133 contains no consequence for lapse of the six month period for final order.

Conclusion: The time limit in Rule 133 of the Central Goods and Services Tax Rules, 2017 is directory; the proceedings are not barred by limitation. This conclusion is against the Respondent.

Issue (ii): Whether the Respondent increased base prices on 15.11.2017 and thereby failed to pass on the benefit of the GST rate reduction under Section 171 of the Central Goods and Services Tax Act, 2017.

Analysis: The Tribunal compared pre- and post-rate-reduction base prices furnished by the Respondent and observed that base prices of the identified products were increased on the very date the reduced tax rate became effective. The Respondent's claim of increased operational costs and loss of input tax credit was considered but found unsubstantiated by cogent documentary evidence. The Tribunal applied the settled principle that a presumption arises that a supplier must pass on rate reductions to consumers, and that this presumption is rebuttable only by clear, cogent and unequivocal evidence substantiating cost increases.

Conclusion: The Respondent indulged in profiteering by not passing on the benefit of the reduction in GST rate from 18% to 5% w.e.f. 15.11.2017, and the DGAP's recomputed profiteered amount is accepted. This conclusion is in favour of the Revenue and against the Respondent.

Issue (iii): Whether interest and penalty can be imposed on the Respondent for the period of violation.

Analysis: The Tribunal noted that imposition of interest under Rule 133(3)(c) of the Central Goods and Services Tax Rules, 2017 was introduced by Notification No. 31/2019-Central Tax dated 28.06.2019 and therefore interest can only be levied from 28.06.2019 onwards. It also noted that Section 171(3A) (penalty) came into force w.e.f. 01.01.2020 and cannot be applied retrospectively to the period of investigation ending 30.09.2019.

Conclusion: Interest is payable by the Respondent on the profiteered amount from 28.06.2019 until deposit; penalty under Section 171(3A) of the Central Goods and Services Tax Act, 2017 cannot be imposed for the period covered by the investigation. The interest conclusion is in favour of the Revenue; the penalty conclusion is in favour of the Respondent.

Final Conclusion: The DGAP's recomputed investigation report dated 14.10.2022 is accepted; the Respondent is directed to deposit the profiteered amount and to pay interest at 18% from 28.06.2019 until deposit, with 50% of the amount (and interest) to be deposited in the Central Consumer Welfare Fund and 50% in the Maharashtra Consumer Welfare Fund.

Ratio Decidendi: Under Section 171 of the Central Goods and Services Tax Act, 2017 a reduction in tax rate must be passed on to recipients by way of commensurate reduction in price and a supplier who increases base prices coincident with the rate reduction bears the burden to rebut the presumption of profiteering with cogent, clear and unequivocal evidence; timelines in Rule 133 of the Central Goods and Services Tax Rules, 2017 are directory where no consequence for lapse is prescribed, and interest and penalty provisions operate only prospectively from their respective effective dates.
