GST Refund Claims
Refunds are due more often than businesses claim them, and the time limit does not care that you were busy.
When a refund arises
- Exports on payment of IGST, or accumulated credit where exported under an LUT
- Inverted duty structure — where your inputs are taxed higher than your output, credit accumulates and can be refunded
- Excess balance in the cash ledger, paid but not needed
- Tax paid in error, including where a supply was wrongly treated
- Supplies to SEZ units, subject to conditions
Inverted duty is the one most often left unclaimed, because the credit sits quietly on the ledger and nobody treats it as money.
Why claims get rejected
- Filed after the time limit. There is one, it runs from a defined date, and it is not extended for being busy.
- Returns not filed or not matching. A refund claim is checked against your filings, and gaps stop it.
- Documentation incomplete. Shipping bills, invoices and bank realisation evidence, all consistent.
- Supplier has not filed, so the credit being claimed is not available.
- Calculation errors in the formula, particularly on inverted duty claims.

What actually delays a refund
Refund applications are rarely refused outright. They are queried, and the query is what turns a few weeks into a few months. The queries repeat, which means they can be anticipated.
- Supplier returns not filed. Credit you are claiming has to appear in the system, and that depends on your supplier — see our page on ITC reconciliation.
- Shipping bill and return data not matching on export refunds. The invoice numbers and values have to agree exactly across the customs and GST systems.
- Bank account not validated on the portal, so the refund is sanctioned and cannot be paid.
- Wrong refund category selected, which cannot always be corrected without withdrawing and refiling.
- The two-year limitation missed. A refund claim has a time limit from the relevant date, and it does not reopen.
Checking these before filing costs an hour. Discovering them through a deficiency memo costs a cycle.
