Resolving GST Head Errors: Judicial Perspectives on Inter-State vs. Intra-State Classification and Inter-Head Tax Adjustments

The Goods and Services Tax (GST) framework, despite its unified approach, is heavily reliant on the precise determination of the "place of supply." A fundamental classification error—treating an intra-State supply as an inter-State supply or vice versa—can lead to the remittance of tax under the incorrect statutory head. When an assessee mistakenly discharges Integrated Goods and Services Tax (IGST) instead of Central Goods and Services Tax (CGST) and State Goods and Services Tax (SGST), the revenue department's conventional response has often been rigid. Instead of acknowledging that the exchequer has already received the funds, authorities frequently invoke Section 73 of the applicable GST enactments to demand the tax afresh under the correct head, coupled with interest and penalties.

This procedural rigidity forces the assessee to pay the tax twice and subsequently initiate a cumbersome refund process for the erroneously paid amount. However, recent judicial pronouncements, particularly from the Karnataka High Court, have begun to challenge this draconian approach, emphasizing statutory adjustment mechanisms over duplicate tax demands.

Judicial Summary: GR Tech Services Pvt. Ltd. Vs Assistant Commissioner of Commercial Taxes (Audit) (Karnataka High Court)

The Karnataka High Court recently addressed this exact predicament in the landmark case of GR Tech Services Pvt. Ltd. Vs Assistant Commissioner of Commercial Taxes (Audit) (Karnataka High Court).

Factual Matrix of the Dispute

The dispute arose during the tax period of 2019-20. The assessee engaged in commercial transactions with M/s. Larsen and Turbo Limited, an entity possessing operational units in both Bengaluru and Chennai. During the initial phases of their engagement, the assessee erroneously raised invoices directed at the vendor's Chennai unit, classifying the transactions as inter-State supplies and consequently discharging IGST.

Upon subsequent internal review, the assessee realized that the invoices ought to have been raised against the vendor's Bengaluru unit, which would classify the transactions as intra-State supplies, thereby attracting CGST and KGST liabilities.

Departmental Action and Adjudication

During an audit, the departmental authorities flagged this discrepancy. The audit observation maintained that the assessee had incorrectly remitted the tax. The department's stance was that the assessee must first discharge the tax liability under the correct heads (CGST/KGST) and subsequently file a separate refund application for the IGST paid under the wrong head, supposedly in alignment with the provisions of the CGST/KGST Act.

Consequently, a Show Cause Notice was issued, culminating in an Adjudication Order under Section 73 (9) of the CGST/KGST Act, demanding the tax along with interest and penalties. The assessee's subsequent appeal was dismissed on the grounds of limitation, leading to a formal demand in Form GST DRC-13. Furthermore, the assessee's attempt to claim a refund for the IGST was rejected by the authorities.
