Erroneous input tax credit refunds attract recovery and compensatory interest without prior reversal of the original refund order.
Monetary refunds of unutilised input tax credit exceeding entitlement under the refund formula may be treated as erroneous refunds recoverable under Section 73. Recovery jurisdiction does not require prior reversal of the original refund sanction through departmental appeal or revision, although it does not permit disregard of a subsisting appellate determination. Sections 73 and 50 impose compensatory interest on erroneous refunds, irrespective of fraud, taxpayer fault, or departmental error in granting the refund. The substituted refund formula applied from its stated effective date, while the later interest-computation rule neither created nor removed the underlying statutory interest liability.
Issues: (i) Whether a monetary refund of unutilised input tax credit can constitute tax erroneously refunded under Section 73 of the Chhattisgarh Goods and Services Tax Act, 2017; (ii) Whether jurisdiction under Section 73 is barred unless the refund order in FORM GST RFD-06 is first reversed through departmental appeal or revision; (iii) Whether Sections 73 and 50 of the Chhattisgarh Goods and Services Tax Act, 2017 authorise interest on an erroneous refund; (iv) Whether the operation of Rule 89(5), subsequently upheld by the Supreme Court, or the later insertion of Rule 88B renders the interest demand impermissibly retrospective; and (v) Whether the rate, period and quantified interest demand require interference.
Issue (i): Whether a monetary refund of unutilised input tax credit can constitute tax erroneously refunded under Section 73 of the Chhattisgarh Goods and Services Tax Act, 2017.
Analysis: Section 54(3) permits refund of unutilised input tax credit. Once accumulated credit is converted into a monetary payment, it is a statutory refund; if it exceeds the entitlement under Section 54(3) read with Rule 89(5), it falls within the erroneous-refund limb of Section 73. The separate expression concerning input tax credit wrongly availed or utilised addresses ledger-stage credit and does not exclude a cash refund originating from input tax credit. The strict construction of taxing statutes does not require an exclusion unsupported by the enacted text.
Conclusion: A monetary refund of unutilised input tax credit is capable of being treated as an erroneous refund under Section 73. Against the assessee.
Issue (ii): Whether jurisdiction under Section 73 is barred unless the refund order in FORM GST RFD-06 is first reversed through departmental appeal or revision.
Analysis: Sections 107(2) and 108 provide appellate and revisional routes to test the legality or propriety of a refund order, whereas Section 73 provides an independent demand-and-determination mechanism for an amount erroneously refunded. None of those provisions makes prior appeal or revision a jurisdictional precondition for Section 73. The Section 73 power is not a general authority to reopen concluded refund adjudications or to disregard a subsisting appellate determination; on the facts, however, no appellate order affirming the refund existed and the notice was founded on the governing Rule 89(5) computation.
Conclusion: Non-invocation of Section 107(2) or Section 108 did not oust Section 73 jurisdiction in the circumstances of the case. Against the assessee.
Issue (iii): Whether Sections 73 and 50 of the Chhattisgarh Goods and Services Tax Act, 2017 authorise interest on an erroneous refund.
Analysis: Section 73(1), (5), (8) and (9) repeatedly link an erroneous refund with interest payable under Section 50. This supplies substantive statutory authority rather than an interest charge based on implication. Interest is compensatory and is not conditional on fraud, fault, or the absence of departmental error in sanctioning the refund. Payment of only the principal amount does not result in statutory closure under Section 73(8), which requires payment of the tax together with applicable interest.
Conclusion: Sections 73 and 50 jointly authorise interest on an erroneous refund. Against the assessee.
Issue (iv): Whether the operation of Rule 89(5), subsequently upheld by the Supreme Court, or the later insertion of Rule 88B renders the interest demand impermissibly retrospective.
Analysis: The substituted Rule 89(5) was operative from 01.07.2017, before both the refund application and the refund sanction. The subsequent Supreme Court decision upheld the existing rule and did not create a new liability. Rule 88B concerns computation of interest and neither creates nor extinguishes the statutory charge arising from Sections 73 and 50. A contrary High Court ruling operative for part of the period did not suspend the rule or create an interest-free interval.
Conclusion: The interest demand is not an impermissible retrospective levy. Against the assessee.
Issue (v): Whether the rate, period and quantified interest demand require interference.
Analysis: The refund was credited on 13.02.2019 and the principal amount was repaid on 08.11.2021. Interest at 18% per annum for 999 days was arithmetically consistent with the quantified demand, and no alternative rate, period, or computation was established.
Conclusion: The interest demand of Rs.44,51,491/- was correctly sustained. Against the assessee.
Final Conclusion: The statutory interest liability arising from repayment of the erroneous inverted-duty refund remains enforceable.
Ratio Decidendi: A monetary refund of unutilised input tax credit exceeding statutory entitlement may be recovered as an erroneous refund under Section 73, and Section 73 read with Section 50 carries compensatory interest without requiring prior reversal of the original refund order through appeal or revision.
