Excess output tax set-off prevents Section 73 demands where no net GST shortfall remains in dispute.
Section 73 cannot support a tax, interest or penalty demand where admitted excess output tax fully offsets disputed ineligible input tax credit and no net short payment remains. Excess output tax paid beyond actual liability falls within the section 54(8)(c) exception, so its refund is not subject to unjust enrichment. A sales-return demand cannot rest on grounds outside the show cause notice; for 2017-18, non-uploading of credit or debit notes on the GST portal did not invalidate otherwise compliant documents. Orders must address material submissions with reasons, and delayed-return interest demands must identify the default months, tax amounts and interest period.
Issues: (i) Validity of the appellate order for want of a reasoned determination of the appellant's submissions; (ii) Whether a notice under section 73 can be sustained where ineligible input tax credit is fully offset by excess output tax paid; (iii) Whether refund of excess output tax paid is subject to unjust enrichment; (iv) Sustainability of the sales-return demand where the adjudicating authority relied on a ground not stated in the show cause notice and credit/debit notes were not uploaded on the GST portal; (v) Sustainability of interest demand for delayed returns where the show cause notice lacked particulars and the quantified demand was unexplained.
Issue (i): Validity of the appellate order for want of a reasoned determination of the appellant's submissions.
Analysis: The appellate order rejected extensive submissions concerning tax set-off, credit/debit notes and delayed-return interest through a bare one-line observation. It did not address the material contentions or disclose any reasoned basis for confirming the demand. This failed the speaking-order requirement and breached the principles of natural justice.
Conclusion: The appellate order was invalid for breach of the principles of natural justice, in favour of the assessee.
Issue (ii): Whether a notice under section 73 can be sustained where ineligible input tax credit is fully offset by excess output tax paid.
Analysis: The excess output tax payment was undisputed and exceeded the disputed ineligible input tax credit. Section 73 is attracted only where tax remains unpaid or short paid, or credit is wrongly availed or utilised. Requiring payment of the disputed amount followed by a separate refund claim, despite an admitted excess payment, would defeat the permissible set-off of tax liability and produce no revenue loss.
Conclusion: No notice under section 73 lay where the admitted excess output tax payment fully offset the ineligible input tax credit; the related tax, interest and penalty demand was unsustainable, in favour of the assessee.
Issue (iii): Whether refund of excess output tax paid is subject to unjust enrichment.
Analysis: Excess output tax paid over the tax actually due was found to fall within the exception in section 54(8)(c). Accordingly, the statutory basis asserted for applying the test of unjust enrichment was unavailable.
Conclusion: Refund of excess output tax paid was not subject to the test of unjust enrichment, in favour of the assessee.
Issue (iv): Sustainability of the sales-return demand where the adjudicating authority relied on a ground not stated in the show cause notice and credit/debit notes were not uploaded on the GST portal.
Analysis: The show cause notice alleged absence of supporting documents, whereas the adjudication order confirmed the demand because the counterparty had not declared a debit note in its returns. The adjudication thereby travelled beyond the scope of the show cause notice. Further, for the disputed 2017-18 period, GSTR-2A was a reconciliation facility and portal declaration of the credit/debit notes was not mandatory; documents otherwise in order could not be invalidated merely for non-uploading.
Conclusion: The sales-return demand and consequential tax, interest and penalty were unsustainable, in favour of the assessee.
Issue (v): Sustainability of interest demand for delayed returns where the show cause notice lacked particulars and the quantified demand was unexplained.
Analysis: The show cause notice did not identify the defaulting months, tax amounts, or period for which interest was claimed. Its stated interest amount also materially differed from the amount in the adjudication order without any disclosed basis. The demand lacked the specificity required by the principles of natural justice.
Conclusion: The interest demand for delayed filing of returns was unsustainable, in favour of the assessee.
Final Conclusion: The asserted liabilities for tax, interest and penalty lacked legal foundation.
Ratio Decidendi: Section 73 cannot be invoked where an admitted excess output tax payment fully offsets the disputed ineligible input tax credit and no net short payment of tax remains.
