What is GST Refund & LUT?
A GST refund is a claim for tax or input tax credit that a taxpayer is entitled to recover, most commonly on exports, supplies to special economic zones, an inverted duty structure where inputs are taxed higher than outputs, or an excess balance in the electronic cash ledger. Claims are filed in Form RFD-01 on the GST portal.
Who needs it
- Exporters of goods or services, whether they export on payment of IGST or under a Letter of Undertaking without paying it.
- Suppliers to special economic zone units and developers, whose supplies are zero-rated.
- Businesses with an inverted duty structure, where the tax on inputs is higher than the tax on the finished supply.
- Taxpayers carrying an excess balance in the electronic cash ledger after their liability is paid.
- Suppliers of deemed exports, and the recipients of such supplies where the claim lies with them.
- Taxpayers who have paid tax twice, paid under the wrong head, or paid on a supply that was never made.
- Taxpayers who have become entitled to a refund because an appeal or an assessment was decided in their favour.
Benefits
- The correct refund route identified, since exports with IGST and exports under LUT follow different procedures.
- A claim supported by the statements and reconciliations the rules require, which is where most claims fail.
- A Letter of Undertaking furnished on time so exports can be made without blocking working capital in IGST.
- Replies to deficiency memos and show-cause notices, and re-filing within the time still available.
- Tracking of the claim through acknowledgement, provisional refund and the final order.

When does a GST refund arise?
A refund arises in a defined list of situations rather than whenever a taxpayer feels out of pocket, and the category chosen governs the documents, the formula and the relevant date. The common categories are below.
| Situation | What is refunded | Main support needed |
|---|---|---|
| Export of goods on payment of IGST | The IGST paid on the export | Shipping bill and matching return data |
| Export of goods or services under a LUT | Accumulated input tax credit | LUT, invoices, and proof of receipt of foreign exchange for services |
| Supplies to a SEZ unit or developer | IGST paid, or accumulated credit | Endorsement by the specified officer |
| Inverted duty structure | Accumulated credit, per the prescribed formula | Rate-wise working of inputs and outputs |
| Deemed exports | Tax paid on the supply | Documents prescribed for deemed export claims |
| Excess balance in the electronic cash ledger | The unused cash balance | Ledger balance on the portal |
| Tax paid in error or twice | The excess tax paid | Payment challans and a reconciliation |
| Refund following an appeal or assessment | The amount the order allows | The order giving rise to the refund |
How long does a GST refund take?
A complete application is acknowledged within the period the rules prescribe, and for zero-rated supplies the officer may grant a provisional refund of the major part of the claim soon after, with the balance following scrutiny. The timetable only holds, though, if the application is complete when filed.
The single biggest cause of delay is the deficiency memo. Because a memo means the application is treated as never having been made, a defect found in week three does not cost three weeks: it sends the claim back to the start, with the two-year limit still running in the background. Where a refund is not paid within 60 days of a complete application, interest becomes payable to the taxpayer at the rate the Act prescribes.
How is an inverted duty structure refund computed?
The refund is not simply the credit left in the ledger. The rules prescribe a formula that compares turnover of the inverted-rated supply with total turnover, applies that proportion to the credit on inputs, and then reduces the result by the output tax payable on that supply. The figures below illustrate the shape of the calculation only.
| Step | Illustrative amount |
|---|---|
| Turnover of the inverted-rated supply in the period | ₹80,00,000 |
| Total turnover in the period | ₹1,00,00,000 |
| Net input tax credit on inputs for the period | ₹9,00,000 |
| Credit attributable to the inverted-rated supply (80% of ₹9,00,000) | ₹7,20,000 |
| Less: output tax payable on the inverted-rated supply | (₹4,00,000) |
| Maximum refund of accumulated credit | ₹3,20,000 |
Two points cause most of the disputes in this category. The formula works on credit on inputs, so credit relating to input services and capital goods does not enter the refundable amount even though it sits in the same ledger. And the computation is period-based, so a claim cannot be improved by selecting months after the event.
Exporting under a LUT: what to get right
The Letter of Undertaking is furnished in Form RFD-11 for each financial year, and its practical effect is that working capital is not parked in IGST that has to be reclaimed. The conditions are straightforward but unforgiving on timing.
- Furnish the LUT for the financial year before making any export without payment of IGST, not after
- Keep the acknowledged LUT on file: banks and customs agents ask for it
- Mention on export invoices that the supply is made under a LUT without payment of IGST
- Report zero-rated supplies correctly in GSTR-1 and GSTR-3B so the refund data reconciles later
- For export of services, keep the foreign inward remittance or bank realisation certificates: receipt of foreign exchange is what evidences the export
- Watch the period within which export proceeds must be realised, because a failure to realise can affect the zero-rated treatment
Why claims get rejected, and what prevents it
Most rejections are not about entitlement. They are about the claim not matching the records the department can see.
- Invoice, shipping bill and return data that do not agree, so the claim cannot be traced to the returns
- Credit claimed that was not reported in the returns for the refund period
- The wrong refund category, which brings the wrong statement format and the wrong relevant date
- An inverted duty claim computed on total credit instead of the prescribed formula
- No evidence of receipt of foreign exchange for an export of services
- A bank account not validated on the portal, or not in the registered person's name
- A fresh application filed after a deficiency memo without the defect having been cured

Due dates and penalties
| Item | Due date | If missed |
|---|---|---|
| Refund application in Form RFD-01 | Within two years from the relevant date for the refund category | The claim is time-barred and cannot be made |
| Letter of Undertaking in Form RFD-11 | Furnished for each financial year, before exporting without payment of IGST | IGST must be paid on exports and recovered later as a refund |
| Reply to a deficiency memo or show-cause notice | Within the time stated in the memo or notice | The application can be rejected |
| Interest on a delayed refund | Payable where the refund is not issued within 60 days of a complete application | Interest accrues in the taxpayer's favour, at the rate the Act prescribes |
The two-year limit runs from the relevant date, which is defined separately for each refund category: for export of goods it is tied to the date of shipment, for export of services to the date the payment is received, and for other categories to the date of payment of tax or the date of the order. Confirm the relevant date for your claim before filing, as the limit cannot be extended.
Mistakes to avoid
- Missing the two-year limit because the relevant date was taken as the invoice date rather than the date the category prescribes.
- Exporting without paying IGST before the Letter of Undertaking has actually been furnished for that financial year.
- Shipping bill and invoice details that do not match the GST return, so the data never transmits or reconciles.
- Claiming refund of credit on input services in an inverted duty structure claim, which the prescribed formula does not allow.
- Filing a fresh application after a deficiency memo without curing the defect that caused it.
- A bank account that is not validated on the portal or is not in the registered person's name, which holds up the payment.
- Claiming a refund of credit that was never reflected in the returns for the period concerned.
