Overview
📌 TL;DR - Wrong Tax Head Services at a Glance
Where a taxpayer paid CGST plus SGST on a supply later held to be inter-state, or IGST on a supply later held to be intra-state, refund of the wrong tax is available under Section 77(1) of the CGST Act 2017 read with Section 19(1) of the IGST Act 2017, provided the correct tax is first discharged and no Section 34 credit note was issued. Per Rule 89(1A) and Circular 162/18/2021-GST, the 2-year limitation runs from the date of payment of the CORRECT tax, not the original wrong payment.

| Filing Form | Form GST RFD-01, reason "Tax paid which is subsequently held as the converse" |

GST classification errors between intra-state and inter-state supply are among the most common compliance failures - particularly in scenarios involving buying agents and intermediaries with foreign clients, e-commerce sellers operating across multiple states, billing-vs-shipping address mismatches, and complex Place of Supply rules under Sections 10 to 13 of the IGST Act 2017. The financial cost of getting it wrong is high - the wrong tax sits paid with one government, while the correct tax is now due to another. Section 77(1) of the CGST Act 2017 and Section 19(1) of the IGST Act 2017 together provide the symmetric refund mechanism that prevents this from becoming a permanent leakage.
The legislative architecture became clear only after the 45th GST Council recommendations led to Notification 35/2021-CT dated 24 September 2021 (inserting Rule 89(1A) of CGST Rules 2017) and Circular 162/18/2021-GST dated 25 September 2021. The circular settled the three biggest open questions - (1) the term 'subsequently held' covers both self-discovery by the taxpayer and officer-discovery in proceedings, (2) Rule 89(1A) applies equally to Section 19 IGST cases even though only Section 77 was textually mentioned, and (3) the 2-year limitation under Section 54(1) starts from the date of payment of correct tax, not the original wrong payment. The Patna High Court 2025 ruling reinforced this position - holding that to read the limitation otherwise would render Sections 77 and 19 nugatory.
