GST Refunds — When and How to Claim
GST refunds arise from exports, inverted duty structure, and ITC accumulation. Here is how to claim, what forms to use, and when the two-year deadline applies.
Introduction
GST refunds happen when a business has paid more GST on inputs than it collected on outputs, or when zero-rated exports create accumulated ITC that cannot be used. Refunds are a legitimate part of the GST system — GST is a tax on consumption, not a cost to doing business.
The most common refund scenario is the inverted duty structure: a business buys inputs at a higher GST rate than the rate on its finished products. The accumulated input tax credit cannot be used against the lower output tax, so a refund claim recovers it.
Key concepts
When can you claim a refund?
Refunds are available for: exports (zero-rated supplies with ITC), inverted duty structure (you paid higher GST on inputs than on outputs), input tax credit accumulation (ITC that cannot be used), and deemed exports.
Inverted duty structure
This is the most common refund scenario. You buy inputs at 18% GST and sell finished goods at 5% GST. Your ITC accumulates because you cannot use it against the lower output tax. You can claim this accumulated ITC as a refund.
Two-year time limit
A refund claim must be filed within two years from the end of the tax period in which the refund arose. After two years, the claim lapses and the credit is permanently forfeited.
Refund process
File Form GST RFD-01 on the GST portal. The officer has 30 days to process the claim (60 days if scrutinised). If not disposed within 60 days, the refund is auto-credited to your electronic cash ledger.
Refund types and examples
| Refund type | Example | Form to use |
|---|---|---|
| Inverted duty structure | Buy at 18%, sell at 5% — ITC accumulates | RFD-01 + calculation statement |
| Export of goods / services | Exporter collects 0% GST but paid input GST | RFD-01 + shipping bill / export invoice |
| Deemed export | Supply to a notified SEZ unit | RFD-01 + deemed export invoice |
| Excess tax paid | Wrong tax rate applied, rectified in return | RFD-01 |
