GST Refund for Exporters: Documents and Risk Flags: FAQ for Founders, CFOs and Individuals

GST refunds for exporters — IGST paid on exports or accumulated ITC under LUT route — are key cash-flow tools. Yet applications are frequently rejected due to documentation gaps and GSTR-1 mismatches. This guide answers common questions and flags the top risk areas.

Use the GST Refund Route and RFD-01 Checklist to apply these points to your figures or facts.

Two Refund Routes for Exporters

Route	Mechanism	Claim Form	Typical Time
Route A: IGST Refund (paid route)	Pay IGST on export; refund via ICEGATE (auto-processed for goods)	Shipping bill auto-link	7–30 days
Route B: ITC Refund (LUT route)	Export without IGST under LUT; accumulated ITC refunded via GST portal	RFD-01 on GST portal	45–75 days

ℹ️

Service Exporters Can Use Either Route: Service exporters most commonly use Route B (LUT, no IGST payment) since there's no shipping bill to anchor an automated Route A claim. But the IGST-paid route is legally available for export of services too — a service exporter can charge and pay IGST on the export invoice and claim it back via RFD-01, instead of filing under LUT. The choice is a cash-flow decision (pay IGST upfront and claim it back, versus exporting without IGST and claiming accumulated ITC), not a legal restriction that forces services into the LUT route.

Document Checklist — RFD-01 ITC Refund

RFD-01 application on GST portal (online; no physical submission)
Export invoices for the claim period
FIRC / bank certificate confirming foreign exchange receipt for each invoice
GSTR-1 extracts showing Table 6A export entries for claim period
GSTR-3B for claim period showing zero-rated supply and ITC claimed
Input tax invoices from GSTR-2B
Statement 3 (for ITC on inputs/input services used in export)
Self-certification or CA/Cost Accountant certificate depending on refund amount and whether unjust-enrichment documentation is required — verify the current threshold and applicable scenario with the jurisdictional officer rather than assuming a fixed Rs.2 lakh cut-off applies uniformly

🚨

Top Rejection Reasons:
1. Export invoice value in GSTR-1 differs from FIRC amount (currency conversion timing)
2. FIRC not obtained for all invoices — partial documentation
3. Prior-period GSTR-3B pending or filed with errors
4. ITC claimed in wrong period (supplier filed late in GSTR-2B)
5. Export classified as domestic supply in GSTR-1 (Table 6 vs Table 4 error)
6. LUT not filed before the export invoice date

Refund Timeline and Remedies for Delay

If refund not processed within 60 days: taxpayer is entitled to 6% interest per annum from the 61st day. Steps: check ARN status → respond to any deficiency memo (RFD-03) within 15 days → write to jurisdictional officer citing Section 54(7) → writ petition in High Court if unresolved.

Exporter refund — route, limitation and evidence must agree

Finin2min answer: An exporter should first identify the statutory refund route—zero-rated supply without payment under LUT/bond with unutilised ITC, or another permitted route—then apply the correct Rule 89/96 mechanics. Refund eligibility is not established by shipping/export documents alone; return data, ITC eligibility, realisation conditions and limitation must reconcile.

Decision table

Situation	2026 treatment / control	Why it matters
Export without payment under LUT	Compute eligible unutilised ITC under Rule 89 and preserve LUT/export evidence.	Not all ledger credit is refundable.
Export with tax payment / other route	Use the currently permitted statutory/portal route.	Do not combine formulas from different refund types.
Service export	Test export-of-services conditions and relevant date.	Foreign remittance/place of supply are central.
Limitation	Track two-year rule from the correct relevant date, subject to specific law.	Do not count mechanically from return filing date.

Worked practical example

A service exporter has ₹8 lakh electronic credit ledger balance but only ₹5 lakh qualifies as Net ITC for the relevant refund formula. Claiming the ledger balance instead of the Rule 89 amount creates a mismatch even though services were genuinely exported.

FAQ

Can I claim export refund for services before GST registration? +

No. ITC and refund claims are available only from the date of registration. Services exported before registration have no ITC trail. This is a key reason to register voluntarily early.

What is the time limit for export refund claims? +

Two years from the relevant date, as defined in the Explanation to Section 54 of the CGST Act. For export of services specifically, the relevant date is the date of receipt of payment in convertible foreign exchange (or Indian rupees where RBI permits) — or, if payment was received before the supply was completed, the invoice date. This is not the GSTR-3B filing date. Monitor the actual relevant date for each invoice — lapsed claims cannot be revived.

Can I switch from LUT route to IGST-paid route mid-year? +

Yes — different routes can be used for different invoices in the same year. However, mixing routes creates reconciliation complexity. Most service exporters stick to LUT route throughout the year for simplicity.
