GST Refund on Exports Under LUT — Accumulated ITC Refund (Rule 89(4))

When you export goods or services without payment of tax under a Letter of Undertaking (LUT, Form RFD-11), you do not charge IGST — so the input tax credit on your purchases accumulates. Under Section 54(3) of the CGST Act, you claim a refund of that accumulated ITC by filing RFD-01 with Statement 3 / 3A for goods or Statement 2 for services (service exports also need BRC/FIRC). The refundable amount is computed under the Rule 89(4) formula: (Turnover of zero-rated supply of goods and services × Net ITC) ÷ Adjusted Total Turnover. The claim window is two years from the relevant date, and 90% may be sanctioned provisionally via RFD-04.

Rule 89(4)

Refund formulaRefund = (Turnover of zero-rated supply × Net ITC) ÷ Adjusted Total Turnover. We compute it correctly so the claim survives scrutiny.

Understand It

What Is Export ITC Refund (LUT)?

A plain-language view of the accumulated-ITC refund route before the mechanics.

In simple terms

It is a refund of the GST you paid on your purchases (input tax credit) that builds up because you export under an LUT and charge no tax on the export. Since the credit cannot be used, you claim it back in cash.

Legally

Exports are zero-rated under Section 16 of the IGST Act. Section 16(3) read with Section 54(3) of the CGST Act allows a refund of unutilised input tax credit where supplies are zero-rated and made without payment of tax under a bond or LUT. Rule 96A governs export under LUT; Rule 89(4) prescribes the formula for the refund of accumulated ITC.

Governing authority

Filed on the GST portal (gst.gov.in) in Form RFD-01 and processed by the jurisdictional CBIC/State refund officer, who may issue provisional (RFD-04), sanction (RFD-06) or deficiency/rejection (RFD-03/RFD-08) orders.

Validity

The refund must be claimed within two years of the relevant date under Section 54. The LUT itself is valid for the financial year in which it is filed and must be renewed each year.

Why It Matters

Why Exporters Use the LUT Route

Exporting under LUT avoids paying IGST upfront, but it leaves your input credit stranded. A correctly computed refund of accumulated ITC returns that blocked working capital.

01

Exports Are Zero-Rated

Under Section 16 of the IGST Act, export of goods and services is zero-rated. Exporting under LUT lets you supply without charging IGST while keeping the exports tax-free.
02

No Working-Capital Blockage

Because you do not pay IGST upfront on the export, cash is not locked in tax you would later reclaim — unlike the payment-of-IGST route.
03

Recover Accumulated ITC

The credit on inputs and input services still accumulates. Section 54(3) lets you claim a cash refund of that unutilised ITC instead of carrying it forever.
04

Rule 89(4) Certainty

The refundable amount is a formula, not a guess: turnover of zero-rated supply × Net ITC ÷ adjusted total turnover. Getting each input right is what protects the claim.
05

Provisional Refund

For zero-rated claims, 90% of the amount may be granted provisionally via Form RFD-04, with the balance after verification — easing cash flow while the claim is examined.
06

Interest on Delay

Where a valid refund is delayed beyond 60 days of a complete application, interest is payable under Section 56 of the CGST Act (6%, or 9% in specified appeal cases).

Checklist

Documents Required for the LUT (ITC) Refund

What you file depends on whether you export goods or services. Keep clear scans and a reconciled ITC working ready — the statement must tie back to your returns.

Goods or services?

Export of Goods

Goods exported under LUT

4 documents

Valid LUT (Form RFD-11) for the FY
Export invoices and shipping bills
Statement 3 / 3A — invoice & shipping-bill wise
GSTR-1, GSTR-3B and GSTR-2B for the period

LUT (RFD-11) must be valid

Export without payment is only allowed under a Letter of Undertaking in Form RFD-11, filed once per financial year. Without a valid LUT for the period, the export should have carried IGST — so confirm the LUT first.

Right statement for the supply

Goods exports use Statement 3 (or 3A); service exports use Statement 2. The statement is invoice-wise and must reconcile with GSTR-1 and the shipping-bill data.

Services need BRC/FIRC

For export of services, receipt of consideration in convertible foreign exchange (or INR where permitted) must be evidenced by a BRC / FIRC and linked to the invoices claimed in Statement 2.

Net ITC drives the amount

Under Rule 89(4), only eligible Net ITC counts — broadly ITC on inputs and input services, excluding ineligible/blocked credit. Getting Net ITC and adjusted total turnover right is what determines the sanctioned amount.

Step by Step

How the LUT (Accumulated-ITC) Refund Works

Unlike the IGST-payment route, this is an active RFD-01 claim — accuracy in the Rule 89(4) computation is everything.

01

File / confirm the LUT (RFD-11)

Ensure a valid Letter of Undertaking is on record for the financial year so exports can be made without payment of IGST.

02

Export under LUT

Raise export invoices with no IGST (mentioning the LUT), and file shipping bills for goods. Credit on inputs accumulates in the credit ledger.

03

Build Net ITC & Rule 89(4) working

Determine eligible Net ITC, turnover of zero-rated supply and adjusted total turnover, then compute the refund under the Rule 89(4) formula.

04

Prepare the statement

Complete Statement 3/3A for goods or Statement 2 (with BRC/FIRC) for services, invoice-wise and reconciled to GSTR-1 / GSTR-3B / GSTR-2B.

05

File RFD-01 and debit the ledger

Submit RFD-01 on the portal for the relevant period, debit the electronic credit ledger for the claimed amount, and generate the ARN.

06

Provisional & final sanction

The officer may grant 90% provisionally via RFD-04, then issue the final sanction (RFD-06) with payment (RFD-05) to your bank account.

How Long It Takes

How Long the LUT Refund Takes

Stage	Expected Time
RFD-01 filed → acknowledgement (RFD-02)	On acceptance of a complete claim
Provisional refund (zero-rated) via RFD-04	Up to 90% of the claim
Deficiency memo (RFD-03) → re-file	Resets on corrected re-submission
Final sanction (RFD-06) & payment (RFD-05)	After verification
Statutory outer limit to make the claim	Within 2 years of the relevant date

For zero-rated refunds, 90% may be sanctioned provisionally via RFD-04 pending verification. Where a valid refund is delayed beyond 60 days of a complete application, interest is payable under Section 56 of the CGST Act (6%, or 9% in specified appeal cases). A deficiency memo (RFD-03) requires a fresh, corrected application.

Answers

Frequently Asked Questions

What is an export refund under LUT?

When you export goods or services without paying IGST under a Letter of Undertaking (LUT), the GST you paid on your purchases accumulates as unutilised input tax credit. Under Section 54(3) of the CGST Act you can claim a cash refund of that accumulated ITC by filing RFD-01 with the appropriate statement.

What is the difference between the LUT route and the IGST-payment route?

Under LUT you export without charging IGST and claim a refund of accumulated input tax credit (an active RFD-01 claim). Under the payment route you pay IGST on the export and get it back automatically, with the shipping bill acting as the refund application. The LUT route avoids blocking working capital in upfront IGST; you choose the route per shipment.

Which statement do I file — Statement 2 or Statement 3?

Statement 3 (or 3A) is used for export of goods and is invoice- and shipping-bill-wise. Statement 2 is used for export of services and must be supported by BRC/FIRC evidencing realisation of foreign exchange. The statement is filed as part of RFD-01 and must reconcile with your returns.

How is the refund amount calculated?

Under Rule 89(4), the maximum refund of accumulated ITC for zero-rated supplies is: (Turnover of zero-rated supply of goods and services × Net ITC) ÷ Adjusted Total Turnover. Net ITC is broadly the eligible ITC on inputs and input services availed during the period, excluding ineligible or blocked credit. Getting Net ITC and adjusted total turnover right is critical to the sanctioned amount.

What is a LUT and how often do I file it?

A Letter of Undertaking in Form RFD-11 is a declaration that lets you export goods or services (or supply to SEZ) without payment of IGST. It is filed online on the GST portal once per financial year and is valid for that whole financial year, so it must be renewed each year.

Do I get a provisional refund?

Yes. For zero-rated supplies, the officer may grant 90% of the claimed refund provisionally through Form RFD-04, with the balance released after verification through the final sanction order (RFD-06). This eases cash flow while the claim is examined.

What is the time limit to claim the refund?

The refund must be claimed within two years of the relevant date under Section 54 of the CGST Act. For export of goods the relevant date is generally the date the goods leave India; for services it is linked to receipt of payment or the date of the invoice, depending on the situation.

Do service exporters need BRC/FIRC?

Yes. For export of services, receipt of consideration in convertible foreign exchange (or in INR where permitted) must be evidenced by a Bank Realisation Certificate (BRC) or Foreign Inward Remittance Certificate (FIRC), and these are linked to the invoices claimed in Statement 2.

Is there interest if my refund is delayed?

Yes. Under Section 56 of the CGST Act, if a valid refund is not paid within 60 days of a complete application, interest is payable at 6% per annum, rising to 9% per annum in specified cases arising from an appellate or court order.

What happens if I get a deficiency memo (RFD-03)?

A deficiency memo means the officer found the application incomplete or defective. You must correct the identified deficiencies and file a fresh RFD-01; the credit ledger debit is typically re-credited so you can re-apply. We handle the correction and re-filing to keep the claim within time.

Can I claim a refund of ITC on capital goods under this route?

Generally no. The Rule 89(4) formula for zero-rated supplies is based on Net ITC of inputs and input services, and does not include ITC on capital goods. We factor this into the Net ITC working so the claim is not over-stated.

Is there any government fee to claim this refund?

No. There is no government fee to file RFD-01 or a LUT. You only pay a professional fee if you engage an expert to compute the refund, prepare the statement and handle the filing and any deficiency response.

Can merchant exporters claim under the LUT route?

Yes. Merchant exporters who export under LUT can claim a refund of accumulated ITC — including credit built up where goods were procured at the concessional 0.1% rate for merchant exports, subject to the applicable conditions. We assess the specific facts before filing.

How do I claim a GST refund on exports under LUT step by step?

Ensure a valid LUT (Form RFD-11) is on record for the financial year, export without charging IGST, then build the Net ITC working and apply the Rule 89(4) formula. Prepare Statement 3/3A for goods or Statement 2 (with BRC/FIRC) for services, reconcile to GSTR-1/3B/2B, and file RFD-01 within 2 years of the relevant date, debiting the electronic credit ledger for the claimed amount.

What is a LUT and who can file it for export refunds?

A Letter of Undertaking in Form RFD-11 is a declaration that lets a registered person export goods or services (or supply to SEZ) without payment of IGST. Any registered person making zero-rated supplies can file it, except one prosecuted for tax evasion exceeding ₹2.5 crore. It is filed once per financial year and renewed each year.

What is the difference between the Rule 89(4) refund and a Rule 96 IGST refund?

Rule 89(4) governs the LUT route — a refund of accumulated unutilised ITC computed by formula, claimed actively through RFD-01. Rule 96 governs the with-payment route — a refund of the IGST actually paid on the export, where the shipping bill is the deemed application for goods. Under LUT there is no IGST refund, only the ITC refund.

Can I claim a refund of ITC on input services and inputs both under LUT?

Yes. Net ITC under Rule 89(4) for zero-rated supplies covers eligible ITC on both inputs and input services availed during the period. It excludes ITC on capital goods and any blocked or ineligible credit under Section 17(5). We segregate the Net ITC so the claim is neither understated nor over-claimed.

What is the relevant date for an export-under-LUT refund?

Under Section 54, for export of goods the relevant date is generally the date the goods leave India; for export of services it is the date of receipt of payment in convertible foreign exchange or the date of the invoice, whichever is later. The 2-year limit to file RFD-01 runs from this relevant date.
