What is GST Refund?

GST refund is the process of claiming back excess tax paid to the government. When the tax paid on inputs (purchases) exceeds the tax collected on outputs (sales), the excess Input Tax Credit (ITC) can be claimed as a refund.

📌 Key Point: GST refund is not automatic. You must file a formal refund application (Form RFD-01) on the GST portal along with supporting documents.

Eligible Scenarios for GST Refund

Export of Goods/Services Zero-rated

Exports are zero-rated supplies. You can claim refund of unutilized ITC on inputs used for exports.

Inverted Duty Structure ITC Accumulation

When tax rate on inputs (18%) is higher than outputs (5%), leading to ITC accumulation.

Deemed Exports SEZ/EOU

Supplies to SEZ units/developers or EOU units are treated as deemed exports eligible for refund.

Excess Tax Payment

If you paid more tax than due due to clerical error or wrong calculation.

Refund for ITC Reversal

If ITC was reversed in error and later found eligible.

Finalization of Provisional Assessment

If provisional tax paid is higher than final assessed amount.
