Additional input tax credit under GST must be passed to homebuyers, with refund, interest, and possible anti-profiteering penalty.

An increase in the ratio of input tax credit to purchase value after GST was found, creating an additional ITC benefit of 0.23% of purchase value. That benefit had to be passed on to identifiable homebuyers under Section 171 of the CGST Act, and the respondent was found not to have done so. The unpassed benefit was quantified at Rs. 11,91,763 and is to be refunded to eligible buyers with interest at 18% per annum from the respective dates of excess collection until actual refund. Penalty under Section 171(3A) is also attracted in respect of the profiteered amount, subject to the proviso on timely deposit.

Issues: (i) Whether the respondent derived benefit of additional input tax credit after introduction of GST; (ii) Whether such benefit was required to be passed on to homebuyers in terms of Section 171 of the CGST Act; (iii) Whether the respondent is liable to refund the profiteered amount along with interest and from which date; (iv) Whether penalty under Section 171(3A) of the CGST Act is attracted.

Issue (i): Whether the respondent derived benefit of additional input tax credit after introduction of GST.

Analysis: Comparison of input tax credit to purchase value for pre-GST and post-GST periods showed an increase from 3.11% to 3.34%, representing an incremental ITC benefit of 0.23% of purchase value. The computation used certified purchase and ITC figures for the relevant towers and units taken within the investigation period.

Conclusion: The respondent derived the benefit of additional input tax credit after the introduction of GST.

Issue (ii): Whether such benefit was required to be passed on to homebuyers in terms of Section 171 of the CGST Act.

Analysis: Section 171 imposes a statutory obligation to pass on tax reductions or additional input tax credit at the time of supply. Rule 133(3)(b) empowers return of amounts not passed on along with interest. The incremental ITC resulted in savings that should have reduced base and cum-tax prices; recipients were identifiable for the relevant units.

Conclusion: The benefit of additional input tax credit had to be passed on to the homebuyers and was not passed on by the respondent.

Issue (iii): Whether the respondent is liable to refund the profiteered amount along with interest and from which date.

Analysis: The additional ITC benefit was quantified as Rs. 10,64,074 with GST @12% amounting to Rs. 1,27,689, totalling Rs. 11,91,763 to be returned to eligible buyers. Rule 133(3)(b) mandates return of unpassed amounts with interest at 18% per annum from the date of collection of excess amounts until refund. The provision for interest is mandatory where recipients are identifiable; reliance on alternative rule for unidentifiable recipients is inapplicable.

Conclusion: The respondent is liable to refund Rs. 11,91,763 to eligible homebuyers along with interest at 18% per annum from the respective dates of collection of the excess amount until actual refund.

Issue (iv): Whether penalty under Section 171(3A) of the CGST Act is attracted.

Analysis: Section 171(3A) imposes penalty equivalent to ten percent of the amount profiteered and came into force w.e.f. 01.01.2020. The period of contravention in this case spans 01.07.2017 to 31.05.2020; the provision applies to profiteering found within that timeframe subject to the proviso concerning deposit within thirty days.

Conclusion: Penalty under Section 171(3A) of the CGST Act is attracted in respect of the profiteered amount unless the proviso conditions for waiver are met.

Final Conclusion: The respondent is required to refund the calculated profiteered amount with statutory interest and is potentially liable for penalty under the applicable provision, resulting in enforcement of restitution and statutory consequences for failure to pass on the benefit.

Ratio Decidendi: Where introduction of GST causes an increase in the ratio of input tax credit to purchase value, the supplier must pass the resulting benefit to identifiable recipients by commensurate reduction in price; failure to do so requires refund of the unpassed amount with interest under Rule 133(3)(b) and attracts penalty under Section 171(3A) when the provision is in force.
