Refund Processing in a Virtual Environment: The Single Interface

Refund Processing explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

Refund processing was originally split — the central authority handled the CGST and IGST portion, the State authority the SGST portion, and a claimant chased two offices for one claim.

That was replaced by a single interface with a single disbursement.

A refund application in FORM GST RFD-01 is filed electronically and assigned to a single jurisdictional officer — central or State — who processes the entire claim, including the portion belonging to the other authority. The sanctioned amount is disbursed as a single payment through the Public Financial Management System, and the settlement between the Centre and the State happens administratively, behind the interface. Circular No. 125/44/2019-GST consolidated the procedure and the earlier circulars on it.

What the single interface changed

One application. RFD-01, filed once, covering all heads.

One processing officer. Whichever authority the taxpayer is assigned to, that officer disposes of the whole claim.

One set of forms. RFD-02 acknowledgement, RFD-03 deficiency, RFD-06 sanction, RFD-05 payment order — issued once, covering all heads.

One disbursement. A single credit to the bank account, through PFMS.

One appeal. Against the single order.

Before this, a claimant could receive a partial disbursement from one authority and a deficiency memo from the other on the same claim.

The consequences for a claimant

Deal with one office. Correspondence, hearings and clarifications go to the assigned officer, whether central or State.

One deficiency memo covers everything. Rule 90(4) puts it beyond doubt: where deficiencies have been communicated under the SGST or UTGST Rules, they shall be deemed to have been communicated under Rule 90(3) along with the deficiencies communicated under that sub-rule.

So a memo issued by either authority is a memo for the whole claim, and the fresh application requirement applies to all of it. Rules 90 and 92 →

One rejection, one appeal. A partial rejection of the SGST portion is part of the same order, appealed once.

Bank account validation matters more. With a single PFMS disbursement, a failed bank validation stops the entire refund, not a portion of it. Rule 10A →

What is uploaded

The application is entirely electronic, and the supporting documents are uploaded with it. Circular No. 125/44/2019-GST specified the statements and declarations to be uploaded for each category, and the portal enforces them.

The practical points:

Upload limits apply. Large claims with hundreds of invoices need the statements in the prescribed format rather than scanned documents.

The statements are validated against the returns. A statement of invoices that does not tie to GSTR-1 or GSTR-2B produces a query.

Additional documents may be sought. The officer may seek further documents, and the response is uploaded on the portal — but note that a request for documents is not a deficiency memo unless issued as RFD-03.

That distinction matters: an informal request does not restart the sixty-day clock; a deficiency memo does.

The provisional refund layer

Rule 91(2), substituted with effect from 01.10.2025, sits on top of the single-interface architecture: the proper officer, on the basis of identification and evaluation of risk by the system, shall make an order in FORM GST RFD-04 within seven days of acknowledgement, with the order not requiring revalidation, and a refusal requiring reasons in writing.

So for an eligible claim, the sequence is:

1. RFD-01 filed;
2. RFD-02 acknowledgement within fifteen days;
3. RFD-04 provisional 90% within seven days of acknowledgement, on system risk evaluation;
4. RFD-05 payment order and PFMS disbursement;
5. RFD-06 final order within sixty days of the complete application.

Practical notes

• Identify the assigned authority at the outset. Correspondence to the wrong office delays nothing formally but wastes time.
• Validate the bank account before filing, since one failure stops the whole disbursement.
• Use the prescribed statement formats. Free-form uploads are queried.
• Distinguish an informal document request from an RFD-03. Only the latter restarts the clock, and only the latter requires a fresh application.
• Track the seven-day provisional window where the claim is eligible — a claim acknowledged and not provisionally sanctioned within seven days should prompt a follow-up.
• Keep the PFMS failure reasons. Where disbursement fails, the reason is usually a bank validation issue that the taxpayer must fix.

Key takeaways

• One application, one officer, one order, one disbursement through PFMS.
• Rule 90(4): a deficiency communicated under the State rules is deemed communicated under the central rule.
• The process is entirely electronic, with prescribed statement formats.
• An informal document request is not a deficiency memo and does not restart the sixty days.
• Rule 91(2) adds a seven-day, system-risk-based provisional sanction on top.
• A failed bank validation stops the entire refund.
