Who is Eligible for GST Refund?

A GST refund arises when the GST you have paid exceeds your actual tax liability. The following situations qualify for a refund under the GST Act:

• Export of goods or services (zero-rated supplies)
• Inverted duty structure — input tax rate higher than output tax rate
• Excess cash balance in electronic cash ledger
• Tax paid on advance when supply is not made or cancelled
• Deemed exports
• Finalisation of provisional assessment
• Tax paid by mistake — wrong head (CGST instead of IGST, etc.)
• International tourist refund

Time Limit for Filing GST Refund

A refund application must be filed within 2 years from the relevant date. Missing this deadline forfeits your right to the refund permanently.

Refund Type	Relevant Date (2-year clock starts from)
Export of goods	Date of shipment / Let Export Order
Export of services	Date of receipt of foreign currency payment
Inverted duty structure	End of financial year in which ITC was accumulated
Tax paid by mistake	Date of payment of tax
Excess cash in ledger	Date of payment creating the excess balance

Step-by-Step: How to File GST Refund (RFD-01)

Step 1 — Log in to GST Portal

Go to gst.gov.in → Login with your credentials → Go to Services → Refunds → Application for Refund.

Step 2 — Select Refund Type

Choose the appropriate reason from the dropdown:

• Refund of ITC on export of goods without payment of tax (LUT/Bond)
• Export of services with payment of IGST
• ITC accumulated due to inverted tax structure
• Excess cash balance in electronic cash ledger
• Others

Step 3 — Select Tax Period

Choose the tax period (month/year) for which you are claiming the refund.

Step 4 — Fill RFD-01 Form

The system auto-populates data from your filed GSTR-1 and GSTR-3B. You need to enter:

• Turnover of zero-rated supply (for exporters)
• Adjusted total turnover
• ITC amount claimed as refund
• Net ITC available
• Bank account details for refund credit

Step 5 — Upload Supporting Documents

Attach the required documents based on your refund type (see list below).

Step 6 — Submit and Note ARN

Submit the form. An ARN (Application Reference Number) is generated — save this for tracking your refund status.

Documents Required for GST Refund

Refund Type	Documents Required
Export of goods (with IGST paid)	Shipping bill, export invoices, GSTR-1 data
Export of goods (LUT/Bond — without IGST)	Shipping bill, BRC/FIRC, LUT copy, export invoices
Export of services	FIRC/BRC (foreign inward remittance), export invoices
Inverted duty structure	Purchase invoices, GSTR-2B data, CA certificate if amount exceeds ₹2 lakh
Tax paid by mistake	Relevant invoices, proof of payment, explanation letter

GST Refund Processing Timeline

Stage	Timeline
Acknowledgement of application (RFD-02)	Within 15 days of filing
Deficiency memo issued (if documents incomplete)	Within 15 days

Common Reasons for GST Refund Rejection

Refund applications are commonly rejected due to:

• Pending GST returns — GSTR-1 or GSTR-3B not filed for relevant period
• Mismatch in invoice data — shipping bill details don't match GSTR-1
• Incomplete documents — missing BRC/FIRC for service exports
• Time limit missed — application filed after 2 years
• Wrong refund category selected
• Bank account not validated on GST portal
• No LUT filed for zero-rated exports without IGST payment

Refund for Exporters — LUT vs IGST Payment

Exporters have two options:

Option 1 — Export under LUT (Letter of Undertaking)

• Export without paying IGST
• Claim refund of accumulated ITC
• File LUT at beginning of financial year on GST portal
• Preferred option — no cash outflow upfront

Option 2 — Pay IGST and Claim Refund

• Pay IGST on exports and claim it back
• Refund is processed automatically via shipping bill data
• Involves upfront cash outflow — not preferred for large exporters

Inverted Duty Structure Refund — Explained

An inverted duty structure occurs when the GST rate on inputs is higher than the GST rate on output. This causes ITC to accumulate since you can't fully set it off against output tax.

Example: A textile manufacturer buys yarn at 12% GST but sells fabric at 5% GST. Input tax exceeds output tax — the excess accumulates and can be claimed as refund.

Frequently Asked Questions

Can I track my refund application status?

Yes. Go to gst.gov.in → Services → Refunds → Track Application Status → enter your ARN number.

Is GST refund taxable income?

No. GST refund is a return of tax paid — it is not business income and not taxable under Income Tax.

My refund was rejected — can I reapply?

Yes. You can file a fresh application after correcting the deficiencies, as long as you are within the 2-year time limit.

Can I get interest if my refund is delayed beyond 60 days?

Yes — the government must pay interest at 6% per annum on refunds not processed within 60 days of receiving a complete application.

What is RFD-01 vs RFD-06?

RFD-01 is the refund application you file. RFD-06 is the final refund order issued by the GST officer after processing — this is when the amount is actually credited to your bank account.
