For an exporter or an inverted-duty manufacturer, GST refunds are not a windfall — they are the recovery of cash already parted with. The law is reasonably generous. What separates businesses that get paid in weeks from those still chasing after a year is almost entirely the quality of the claim documentation and how quickly a deficiency memo is answered.
The three situations that produce a refund
| Situation | Route | What comes back |
|---|---|---|
| Exports with LUT, no IGST paid | Refund of unutilised input tax credit | Accumulated ITC on inputs |
| Exports with IGST paid | Shipping bill acts as the application | The IGST paid on the export |
| Inverted duty structure | Refund of unutilised ITC, formula-based | Credit accumulated because inputs are taxed higher than output |
There is a fourth, simpler case: excess balance sitting in the electronic cash ledger, which is money you deposited but never needed. That one is close to automatic and is frequently forgotten entirely.
The inverted-duty formula is the one to model carefully — it does not refund tax on input *services*, only on input goods, so a service-heavy cost base recovers far less than the raw credit balance suggests.
The two-year clock
A refund application must be filed within two years of the relevant date, and the relevant date differs by situation — the date of export for goods, the date of receipt of payment for services, the date of the return for accumulated credit. Businesses that let claims accumulate to make one large application are the ones who discover that the earliest quarters have expired.
File refunds on the same cadence you file returns. A quarterly refund habit beats an annual reconciliation exercise, because the two-year window closes quarter by quarter, not all at once.
The forms, in the order you will meet them
- RFD-11 — the letter of undertaking, filed once each financial year, that lets you export without paying IGST.
- RFD-01 — the refund application itself, with statements and supporting documents.
- RFD-02 — acknowledgement, which starts the clock on the department.
- RFD-03 — deficiency memo. This is the one that matters: it sends the claim back, and the corrected claim is treated as a fresh application.
- RFD-04 — provisional refund, typically 90% for zero-rated supplies.
- RFD-06 — the final sanction order.
Interest is payable if the refund is delayed beyond the statutory period from the date of acknowledgement — but note that a deficiency memo resets the sequence, which is precisely why sloppy first submissions are expensive even when the underlying claim is sound.
What a clean claim looks like
- GSTR-1 and GSTR-3B filed and consistent for every period in the claim.
- Shipping bills and invoices matching on value, GSTIN and port code — a single digit wrong on the shipping bill blocks the automated IGST route entirely.
- Realisation evidence for services, and eBRC where required.
- A working ITC reconciliation tying the claimed credit to GSTR-2B — see input tax credit and the invoice management system for the upstream discipline this depends on.
- The LUT valid for the period of export, not filed retrospectively after the shipment.

Where we come in
We run refund cycles as a routine rather than a rescue — LUT filed on time each year, claims prepared quarterly, and reconciliations kept in a state where a deficiency memo can be answered in days. Our GST services cover the whole cycle, and GST audit where the position needs defending.
