The Madras High Court held that Section 19 IGST Act does not apply when a taxpayer merely pays tax under the wrong GST head. Instead, the GST authorities must adjust the amount rather than demand fresh payment and a later refund. The Court ruled that a taxpayer who pays the full tax liability on time cannot face hardship because of a clerical mistake. Justice Senthilkumar Ramamoorthy allowed the writ petition filed by SYA Homes. He set aside the rectification order that required the petitioner to first pay CGST and SGST before claiming a refund of the IGST amount.
Factual Matrix
The dispute arose after the petitioner mistakenly paid its entire GST liability of ₹5.84 lakh under the IGST head while filing the GSTR-3B return for September 2021. It should have split the amount equally between CGST and SGST.
The GST Department directed the petitioner to first pay CGST and SGST and then apply for a refund of the IGST amount. It also attached the petitioner’s bank account to recover the alleged dues.
The petitioner argued that it had already paid the entire tax liability within the prescribed time. It submitted that the only mistake was selecting the wrong tax head while filing the return. It requested the authorities to transfer the amount to the correct heads instead of demanding another payment.
Department’s Submissions
The Department relied on Section 19 of the IGST Act read with Rule 89(1A) of the CGST Rules. It argued that the petitioner had to first pay the CGST and SGST liability and only then seek a refund of the IGST amount.
According to the Department, the statutory scheme required taxpayers to follow the refund mechanism whenever tax was paid under the wrong head.
Findings of the High Court
The High Court rejected the Department’s interpretation. It held that Section 19 IGST Act applies only when a taxpayer wrongly treats an inter-State supply as an intra-State supply or vice versa.
The Court explained that Section 19 of the IGST Act, Section 77 of the CGST Act, and Rule 89(1A) operate only after authorities determine that the nature of a supply has changed. These provisions do not apply when a taxpayer simply deposits tax under the wrong GST head.
The Court also noted that the rectification order admitted the petitioner had already paid the full tax liability of ₹5.84 lakh. Since the payment was made within time, the authorities could not demand the same tax again because of a procedural error.
The Court distinguished a genuine dispute over the nature of supply from a simple payment-head mistake. It held that only the former attracts the statutory refund mechanism.
Directions Issued
The Court directed the petitioner to file an application seeking adjustment of the amount paid under IGST towards its CGST and SGST liability.
It also directed the GST authorities to complete the adjustment within 30 days of receiving the application. The Court set aside the rectification order to the extent that it required a fresh payment before refund.
Statutory Context
The judgment highlights the difference between disputes over the nature of a supply and errors in selecting the tax head.
Section 19 of the IGST Act and Section 77 of the CGST Act address cases where a taxpayer mistakenly treats a supply as inter-State or intra-State. Rule 89(1A) provides the refund procedure after the correct classification is determined.
The Court held that these provisions do not govern cases where the taxpayer correctly identifies the supply but accidentally chooses the wrong payment head on the GST portal.
Significance
The ruling strengthens the principle that procedural mistakes should not force taxpayers to make duplicate payments when the Government has already received the correct amount.
The judgment also limits the use of coercive recovery measures, including bank account attachment, where there is no revenue loss. It gives taxpayers a strong precedent to seek adjustment of tax paid under the wrong GST head instead of following a costly pay-first, refund-later process.
