GST Refund — Types, Process & Time Limit
Businesses can claim a refund of GST paid in several situations — exports, an inverted duty structure, or excess balance in the cash ledger. Here are the refund types, the RFD-01 process, and the time limits.
A GST refund arises when the tax paid or the input tax credit accumulated exceeds the liability. Timely refunds are vital for exporters and businesses with an inverted duty structure, where working capital would otherwise stay locked in the GST system.
Most refunds are claimed online in Form RFD-01 within two years of the relevant date.

Frequently Asked Questions
What is the time limit to claim a GST refund?
Generally two years from the relevant date, which differs by refund type (e.g., date of export, date of payment of tax).
How do I claim a GST refund on exports?
Exports with IGST payment get an auto-processed IGST refund from shipping-bill data; exports without payment under LUT claim a refund of unutilised ITC via Form RFD-01.
What is an inverted duty structure refund?
When the GST rate on inputs is higher than on the output supply, unutilised input tax credit accumulates and can be refunded, subject to the prescribed formula and exclusions.
How long does a GST refund take?
Refunds should be sanctioned within 60 days of a complete application; if delayed beyond that, interest at 6% per annum is payable, and exporters can get a provisional 90% refund.
Which form is used to claim a GST refund?
Form RFD-01 is filed online on the GST portal, with category-specific statements and supporting documents.
