GST Refund Assistance in Coimbatore

GST refunds get stuck for one of three reasons: incomplete documentation, a mismatch between the refund claim and filed returns, or missing the two-year limitation window. We file and track export refunds (with and without payment of tax), inverted duty structure refunds for spinning mills and manufacturers, and excess balance refunds for Coimbatore businesses, keeping every claim tightly reconciled with GSTR-1 and GSTR-3B before submission.

The main refund categories under Section 54

Export of goods or services under a Letter of Undertaking (LUT), without payment of IGST, is the most common refund category for Coimbatore’s export-facing businesses — the exporter claims a refund of accumulated, unutilised input tax credit attributable to the zero-rated supply. Where IGST is paid at the time of export instead, the refund flows automatically through the shipping bill and ICEGATE integration for goods, without a separate RFD-01 filing — though for services, the RFD-01 route still applies. Inverted duty structure refunds under Section 54(3) apply where the GST rate on inputs is higher than on outputs, leaving credit that can never be fully utilised against output liability — common in textile processing where raw material and job-work rates don’t always mirror the finished-goods rate. Excess balance in the electronic cash ledger — money paid in that was never actually needed against a liability — can be claimed back at any time, since no specific “relevant date” event applies the way it does for exports.

Provisional refunds, certification, and unjust enrichment

For zero-rated (export) and inverted duty structure claims, Section 54(6) and Rule 91 entitle the applicant to a provisional refund of 90% of the claimed amount within 7 days of acknowledgment, with the balance 10% released after full verification — a mechanism specifically designed to protect exporter working capital rather than tying up cash for the full 60-day cycle. Every refund claim above ₹2 lakh needs supporting certification confirming the tax burden wasn’t passed on to another party (the “unjust enrichment” principle under Section 54(8)); claims of ₹2 lakh or below can rely on a simple self-declaration instead. Getting this certification requirement right matters — a refund otherwise eligible on the merits can still be held up purely on a documentation gap here.

What’s included

• Export refund (zero-rated supply) filing, with or without IGST payment
• Inverted duty structure refund for manufacturers where input tax exceeds output tax
• Excess balance in electronic cash ledger refund
• Refund of tax paid on deemed export supplies
• Deficiency memo response and refund re-filing
• Refund status tracking (RFD-01 through RFD-06) on the GST portal

Our process

1. Eligibility check — We confirm which refund category applies — zero-rated export, inverted duty, or excess cash ledger — and check the statement/annexures required for that specific category.
2. Reconciliation — Export invoices, shipping bills, and GSTR-1/3B figures are reconciled to ensure the refund amount claimed matches what's actually reported and eligible.
3. RFD-01 filing — The refund application is filed online with the appropriate statement (Statement 3 for exports, Statement 1 for inverted duty, etc.) and supporting documents.
4. Deficiency memo handling — If the officer issues a deficiency memo (RFD-03), we correct the gap and refile promptly, since deficiency memos don't extend your original limitation period.
5. Disbursal tracking — We track the claim through provisional sanction (90% for exporters, where applicable) to final order and disbursal, following up on delays past the 60-day statutory disposal timeline, and computing the Section 56 interest due on any delay.

Common mistakes that delay Coimbatore refund claims

The most frequent issue is a mismatch between the refund amount claimed and what GSTR-1/GSTR-3B actually reported for the period — the refund system cross-checks against your own filed returns, so an inflated or misaligned claim triggers a deficiency memo almost automatically. For exporters, an expired or improperly filed LUT at the time of the export invoice is a recurring problem — the LUT needs to be valid for the financial year in which the export occurred, and a lapsed LUT can convert what should have been a zero-rated supply into one requiring IGST payment first. We also see inverted duty refund claims filed using the wrong period’s accumulated credit figure, since the formula under Rule 89(5) is specific about which tax period’s ITC accumulation counts — using the wrong base figure is a quiet but common source of rejection.

Documents you’ll need

• Shipping bills / export invoices (for export refunds)
• GSTR-1 and GSTR-3B for the refund period
• Statement of relevant invoices as prescribed for the refund category
• Bank realisation certificate (BRC/FIRC), for export refunds
• Purchase invoices supporting the inverted duty claim
• Electronic cash/credit ledger statements from the GST portal

Step by step: filing Form GST RFD-01 and handling what comes after

1. File Form GST RFD-01 on the portal for the relevant category (export without payment of tax, inverted duty structure, excess cash ledger balance, and so on), with the category-specific statement of invoices attached.
2. An acknowledgement is issued in Form GST RFD-02 once the application is found complete — no deficiency memo can be issued after RFD-02 is generated.
3. If the officer finds the application incomplete or the supporting documents insufficient, a deficiency memo is issued in Form GST RFD-03, typically within 15 days — this treats the original application as never filed. You must correct every point raised and refile fresh in Form GST RFD-01, which gets a new ARN.
4. For eligible export-related categories, up to 90% of the claimed amount can be sanctioned provisionally in Form GST RFD-04, usually within 7 days of the RFD-02 acknowledgment.
5. The final order is issued in Form GST RFD-06, generally within 60 days of the RFD-02 date, confirming the sanctioned amount, any rejected portion, and reasons. Payment is then directed via Form GST RFD-05.
6. If the officer proposes to reject all or part of the claim, a show-cause notice is issued in Form GST RFD-08, and you must reply in Form GST RFD-09, typically within 15 days, before the final order is passed.

A point worth flagging clearly: the two-year limitation period under Section 54 for filing the refund claim keeps running through a deficiency-memo cycle — refiling after an RFD-03 does not extend it, so a claim that’s close to the two-year mark needs to be got right the first time, not treated as having an open-ended runway to fix and refile.

Specimen structure for a refund application cover statement

Section	What it must contain
ARN & category	Application Reference Number, refund category selected, and the tax period(s) covered.
Refund computation	The exact formula applied (Rule 89, for zero-rated/inverted duty categories) with each input figure traced to GSTR-1/3B and the invoice-level statement.
Supporting statement	The prescribed annexure (Statement 3/3A for exports, Statement 1/1A for inverted duty, and so on) matching the category selected — using the wrong statement format is a common cause of an avoidable RFD-03.
Declaration	The undertaking that the incidence of tax has not been passed on to any other person (unjust enrichment), except for the categories exempted from this requirement.
Bank & realisation proof	BRC/FIRC for export categories, and bank account validation as required by the portal.

GST Refund Assistance across Coimbatore’s industries and areas

Refund work in Coimbatore is dominated by two very different profiles. Spinning mills and textile processing units along Tirupur Road and Avinashi Road are the city’s heaviest users of inverted duty structure refunds, given how routinely input rates on raw material and job-work outpace output rates on finished yarn and fabric — for many of these units, refund cash flow is a genuine, recurring part of working capital planning, not an occasional claim. IT and services exporters in Saravanampatti and Peelamedu are the other major category, filing LUT-based zero-rated export refunds tied to FIRC and foreign remittance documentation — for this group, the discipline is less about the refund formula and more about keeping export invoicing, LUT validity, and foreign exchange receipt paperwork tightly aligned from the outset. Manufacturers in Singanallur and Ganapathy see a mix of both inverted duty and occasional excess cash ledger refunds, depending on their specific input-output rate structure.

If a refund is rejected, not just delayed

A deficiency memo (RFD-03) simply means the application needs correction and refiling — it isn’t a rejection, and CBIC Circular 135/05/2020-GST confirms that chronological filing restrictions don’t apply to a fresh application filed after a deficiency memo, so refiling promptly doesn’t forfeit your place in the queue. An actual rejection order (RFD-06 rejecting the claim, or a partial sanction you disagree with) is a different matter — it’s an appealable order under Section 107, on the same three-month timeline as any other adverse GST order, and the pre-deposit and grounds-of-appeal process described in our GST Appeals service applies equally to a rejected refund claim.
