GST Refund Process: RFD-01, Forms and Timelines

The GST refund process runs through a single application — Form GST RFD-01, filed online on the GST portal — and ends with a payment order in RFD-05 that pushes money to your validated bank account. Between those two points sit an acknowledgement in RFD-02 or a deficiency memo in RFD-03, a statutory 60-day clock on the officer, and, if you are claiming on zero-rated supplies, a provisional payout of 90% of the claim that should reach you long before the final order does.

What actually counts as a GST refund

"Refund" under GST is broader than getting back money you overpaid. Section 54 of the CGST Act covers a set of situations where tax or credit has become stuck in the system and needs to come back out, and the money can come from either of two places: your electronic cash ledger, where actual cash you deposited is sitting unused, or your electronic credit ledger, where input tax credit has accumulated faster than you can use it.

The distinction matters more than it looks. A cash-ledger refund is genuinely your money returning. An ITC-based refund is the government converting a credit balance into cash, which is why it is only allowed in the narrow circumstances the law specifies — principally zero-rated supplies and the inverted duty structure — and why it carries far more documentation. Note also that when you file an ITC-based refund claim, the amount is debited from your electronic credit ledger at the point of filing, not at the point of sanction. That money is out of circulation while the claim is pending.

One threshold worth knowing: no refund is granted where the amount claimed is less than ₹1,000. Small residual balances are simply not worth the department's processing effort, and the statute says so.

Refund categories and picking the right one

When you open RFD-01 on the portal, the first thing you do is choose a refund category from a dropdown. This choice is not cosmetic — it determines which statements you must upload, which supporting documents the officer expects, whether provisional refund applies, and how the relevant date for limitation is computed. Picking the wrong category is one of the more common causes of a deficiency memo.

The categories in the live dropdown do change as new ones are notified — a route for unregistered persons to claim back tax on cancelled contracts was added after the original list, for instance. Treat the table above as the shape of the system rather than a definitive enumeration, and check the CBIC GST portal for the current list and the circular governing your specific category.

The GST refund process on the portal: RFD-01 and the ARN

RFD-01 replaced the older semi-manual RFD-01A route, and the whole cycle — application, acknowledgement, notices, replies, orders and disbursement — now sits in one place on the portal. The sequence is:

1. Select the refund category and the tax period, then let the portal pull your ledger balances.
2. Upload the statement relevant to your category (the export invoice statement, the inverted-duty statement, and so on) and any supporting documents — up to ten attachments is the usual limit.
3. Declare the refund amount head-wise across IGST, CGST, SGST/UTGST and cess. For ITC claims, this debits your electronic credit ledger immediately.
4. Select a bank account that has been successfully validated against PFMS. An unvalidated or dormant account is a very common reason for a sanctioned refund never actually arriving.
5. Submit with DSC or EVC. The portal generates the ARN, a 15-character Application Reference Number, which is your handle on the claim from that point on.

Record the ARN against the claim in your books straight away. Every subsequent notice, order and payment references it, and if you end up chasing a stalled refund with the jurisdictional office, it is the first thing they will ask for.

Exports: the LUT route versus paying IGST

Exports and supplies to SEZs are zero-rated, and the law gives exporters a genuine choice of route. The choice has real cash-flow consequences, so it is worth making deliberately rather than by inertia.

Route 1 — export under LUT, without payment of IGST

You furnish a Letter of Undertaking in Form RFD-11 on the portal, generally at the start of each financial year, and then export without charging IGST on the invoice. Because no output tax is paid, input tax credit accumulates, and you claim that accumulated ITC back through RFD-01 under the "ITC accumulated due to exports without payment of tax" category. The refundable amount is not simply your whole credit balance: it is computed by apportioning Net ITC in the ratio of zero-rated turnover to adjusted total turnover, so a business with both domestic and export sales gets back only the export share.

Route 2 — pay IGST on the export, then claim it back

You charge IGST on the export invoice, pay it, and claim it back. For export of goods, this route is unusually clean: no separate RFD-01 is filed at all. The shipping bill is treated as the refund application, and the claim is validated by matching the invoice data you report in your GSTR-1 export tables against the shipping bill data at ICEGATE, with the tax payment confirmed from your GSTR-3B. Get either the invoice number or the GSTIN wrong in one of those places and the refund silently fails to transmit. For export of services with payment of tax, you do file RFD-01, with proof of receipt of convertible foreign exchange.

Inverted duty structure refunds

An inverted duty structure exists when the GST rate on your inputs is higher than the rate on your output supply — a textile processor buying 18% chemicals to make a 5% output, for example. Credit piles up that you can never fully use against output tax, so the law lets you claim the excess back.

The formula in Rule 89(5) is stated in symbols in the rule, but it is easier to hold in your head as three steps:

1. Take Net ITC — credit availed during the period on inputs only. Input services and capital goods are excluded. This single exclusion is why the refund is nearly always smaller than the credit balance you are actually carrying.
2. Apportion it: multiply Net ITC by the turnover of the inverted-rated supply, divided by your adjusted total turnover. That gives the share of credit attributable to the inverted supply.
3. Subtract the tax payable on that inverted-rated supply, itself scaled by the ratio of Net ITC to total ITC availed on inputs and input services. What remains is the maximum refund.

The formula has been amended more than once, and the third step in particular reflects a later correction. Do not compute a claim from memory or from an old spreadsheet template — read the current text of Rule 89(5) before you file.

Two further constraints. Refund of accumulated credit is not available where the output supply is nil-rated or fully exempt, and the government has power to notify specific goods and services for which inverted-duty refunds are simply not allowed. Both are worth checking against your own HSN before building a claim. The GST 2.0 rate restructuring also reshuffled which products sit in which slab, so a business that was not inverted before the change may be inverted now, and vice versa.

The provisional 90% refund for zero-rated supplies

Because export refunds are working-capital-critical, section 54(6) provides that claims arising from zero-rated supplies get a provisional refund of 90% of the amount claimed, sanctioned in Form RFD-04 on a fast track — within seven days of the acknowledgement — with the balance settled after the officer completes scrutiny and passes the final RFD-06 order.

Two things to understand about the provisional amount. First, it is provisional: if the final order sanctions less, the excess is recoverable, so do not treat it as final income until RFD-06 lands. Second, the provisional route is normally not extended to applicants flagged as risky, and the department has repeatedly used risk parameters to route some export refunds through full pre-sanction verification instead. A clean filing history and correctly reported export invoices are the practical way to stay out of that queue.

Both of the ITC-based refund routes depend on the credit in your ledger actually being eligible, and eligibility depends on your suppliers having filed. Reconciling against GSTR-2B before you compute Net ITC, and checking that the suppliers behind your largest input invoices are still active on the GSTIN register, catches the kind of problem that otherwise surfaces as a partial rejection months later. The input tax credit rules that govern eligibility apply in full to refund claims — a refund cannot rescue credit that was never claimable.

Deficiency memos, RFD-03 and re-filing

After you file, the officer scrutinises the application for completeness — not merits — and issues one of two things within fifteen days: an acknowledgement in RFD-02, or a deficiency memo in RFD-03.

RFD-03 means something is missing or inconsistent: a statement not uploaded, a mismatch between the claimed amount and the ledger, an unvalidated bank account, the wrong category selected, or documents that do not support the amount claimed. It is not a rejection and there is nothing to appeal against. What happens instead is:

• The application is closed and the ARN is dead.
• Any amount debited from your electronic credit ledger when you filed is re-credited to that ledger.
• You correct the deficiency and file a fresh RFD-01, which receives a new ARN and restarts the clock.

The trap is limitation. Re-filing restarts the processing timeline but the two-year window under section 54 keeps running from the original relevant date, so a claim filed close to the deadline and hit with a deficiency memo can run out of time. File early enough to survive one round of RFD-03.

Separately, if the officer takes up the application on merits and proposes to reject all or part of it, that comes as a show-cause notice in RFD-08. You reply in RFD-09 within the period stated in the notice — typically fifteen days — and the officer then passes the final order in RFD-06. That order is appealable. RFD-07 covers the two other outcomes: adjusting the refund against an outstanding demand, or withholding it.

Two-year limitation, the 60-day clock and interest

Section 54 gives you two years from the "relevant date" to make the application. The relevant date is not a single concept — it is defined category by category, and using the wrong one is how otherwise valid claims become time-barred.

On the department's side, section 54(7) requires the proper officer to pass the final order within sixty days of receipt of a complete application. That word does the work: the sixty days run from a complete application, which is why a deficiency memo and re-filing effectively reset it.

If the refund is not paid within those sixty days, section 56 provides interest at 6% per annum, running from the day after the sixty-day period ends until the refund is actually paid. Where the refund arises from an order of an appellate authority, tribunal or court that has attained finality and is still not paid within sixty days of the application made consequent to that order, the rate is 9% per annum. Interest is not automatic in practice — you will often have to ask for it, computed from the ARN date — so keep the dates documented. Rates are notified and can be revised; verify the current figures on cbic-gst.gov.in before making a claim.
