Rule 89 CGST Rules: Application for Refund in FORM GST RFD-01
Updated 11 October 2026 · Fact-checked
Rule 89 says how you claim a GST refund. You file FORM GST RFD-01 electronically on the common portal, directly or through a notified Facilitation Centre. You attach the documents in Rule 89(2) that fit your type of refund, plus a no-pass-on declaration (up to ₹2 lakh) or a CA/CMA certificate (above ₹2 lakh).
Understand Application for Refund under Rule 89
A refund is a right under the Act, but you must claim it in the prescribed way. Rule 89 is that procedure. It covers a refund of any balance in the electronic cash ledger, or of any tax, interest, penalty, fees or any other amount you paid. The one exception is refund of integrated tax paid on goods exported out of India, which Rule 89(1) excludes and which follows a separate procedure. Rule 89(1B) separately covers additional integrated tax paid on an upward price revision after export.
The application goes in FORM GST RFD-01, filed electronically on the common portal. You can file directly or through a Facilitation Centre notified by the Commissioner. Persons covered by a notification under section 55 are outside Rule 89(1). Filing is also subject to Rule 10B.
The officer needs proof that a refund is really due. So Rule 89(2) asks for documents in Annexure 1 of RFD-01, and each type of claim has its own list. An export-of-goods claim needs shipping bill and export invoice details. An export-of-services claim needs invoice and BRC/FIRC details. An SEZ supply claim needs invoices, the SEZ officer's endorsement and a declaration that tax was not collected from the SEZ unit or developer.
The law also guards against unjust enrichment. If you claim up to ₹2 lakh, you give a declaration that the tax incidence was not passed on. If you claim more than ₹2 lakh, you give a certificate in Annexure 2 of RFD-01 from a chartered accountant or cost accountant. Where tax was recovered from the recipient, the incidence is deemed passed on to the ultimate consumer.
Finally, if the claim is for input tax credit, you must debit the electronic credit ledger by the refund amount claimed (Rule 89(3)). Rule 89(4) and 89(5) give the formulas for zero-rated supply without tax payment and for inverted duty structure.
Key rules to remember
- Who files and how
- FORM GST RFD-01, electronically, on the common portal (directly or via notified Facilitation Centre)
- Rule 89(1). Not for refund of IGST paid on exported goods. Subject to Rule 10B. Persons covered by a section 55 notification are excluded.
- Unjust enrichment: claim up to ₹2 lakh
- Claim ≤ ₹2,00,000 → declaration that incidence of tax has not been passed on
- Rule 89(2)(l). The text says 'does not exceed two lakh rupees', so exactly ₹2 lakh needs only a declaration.
- Unjust enrichment: claim above ₹2 lakh
- Claim > ₹2,00,000 → Annexure 2 certificate from a CA or cost accountant
- Rule 89(2)(m). No certificate for an unregistered person who has borne the incidence of tax.
- Exempt from declaration/certificate
- Only where the claim falls within clauses (a), (b), (c), (d) or (f) of section 54(8)
- The provisos to Rule 89(2)(l) and (m) say neither a declaration nor a certificate is needed in these cases. Rule 89 does not describe what those clauses cover, so confirm which clause your claim falls under in section 54(8) itself before claiming the exemption.
- ITC refund ledger debit
- Debit electronic credit ledger by the refund of ITC claimed
- Rule 89(3).
- Zero-rated supply without tax (bond/LUT)
- Refund = (Turnover of zero-rated goods + Turnover of zero-rated services) × Net ITC ÷ Adjusted Total Turnover
- Rule 89(4). Goods turnover is the lower of the zero-rated value and 1.5 times the value of like goods supplied domestically, as declared by the supplier. Export value is the lower of FOB value in the shipping bill and the invoice value.
- Inverted duty structure
- Max refund = {(Turnover of inverted rated supply of goods and services × Net ITC) ÷ Adjusted Total Turnover} − {tax payable on such supply × (Net ITC ÷ ITC availed on inputs and input services)}
- Rule 89(5). Net ITC here means ITC availed on inputs during the relevant period.
How to solve Application for Refund under Rule 89 questions
For any question on refund application under Rule 89, identify the type of claim first. The documents, declaration and ledger entry all follow from it.
- 1Identify the nature of the refund: export of goods or services, SEZ supply, deemed export, inverted duty, excess payment, order-based refund, or other.
- 2Confirm Rule 89(1) applies: the person is not covered by a section 55 notification, and the claim is not refund of IGST paid on exported goods.
- 3State the form and mode: FORM GST RFD-01, electronically through the common portal, directly or via a notified Facilitation Centre.
- 4Pick the matching document from Rule 89(2) clauses (a) to (kb) and list it with its key contents.
- 5Apply the unjust enrichment test: compare the claim with ₹2 lakh to choose a declaration or a CA/CMA certificate, then check whether the section 54(8) exemption applies.
- 6If ITC is being refunded, say that the electronic credit ledger is debited by the refund claimed. Apply the Rule 89(4) or 89(5) formula where the question gives figures.
- 7Close with a clear conclusion on what to file and attach.
Quickest way: Claim type, then document, then declaration
When to use it: Use for MCQs and short notes where you must name the document or the unjust enrichment requirement quickly.
- Match the key word in the question to the clause: shipping bill is (b), BRC/FIRC with services is (c), SEZ goods is (d), SEZ services is (e), deemed export is (g), inverted rate is (h), final assessment is (i), inter-State is (j), excess payment is (k).
- Check the amount: up to ₹2 lakh is a declaration, above ₹2 lakh is a CA/CMA certificate.
- Check for the section 54(8)(a), (b), (c), (d), (f) exemption. If it applies, neither is needed.
- If it is an ITC refund, add the ledger debit under Rule 89(3).
Common mistakes in Application for Refund under Rule 89
Saying a certificate is needed for every refund above ₹2 lakh.
Students remember the limit but forget the provisos.
Fix: Always add: no certificate for cases under section 54(8) clauses (a), (b), (c), (d) and (f), and none for an unregistered person who has borne the incidence of tax.
Treating ₹2 lakh exactly as needing a certificate.
Loose reading of the limit.
Fix: The declaration applies where the claim does not exceed ₹2 lakh. A certificate is needed only above ₹2 lakh.
Applying Rule 89 to refund of IGST paid on exported goods.
Both are export refunds.
Fix: Rule 89(1) excludes refund of integrated tax paid on goods exported out of India, and such a refund follows a separate procedure. Rule 89(1B) covers only the additional IGST paid on an upward price revision after export.
Forgetting to debit the electronic credit ledger in an ITC refund.
Focus stays on the form and documents.
Fix: Under Rule 89(3), the applicant debits the electronic credit ledger by the amount of refund claimed.
Mixing up who files in SEZ and deemed export cases.
The provisos look similar.
Fix: For SEZ supplies, the supplier of goods files after the goods are admitted in full in the SEZ for authorised operations, as endorsed by the specified officer. The supplier of services files with evidence of receipt of services for authorised operations, as endorsed by the specified officer. For deemed exports, the recipient may file, or the supplier if the recipient does not avail ITC and gives an undertaking.
Filing a refund of the advance tax deposit before the last return.
The last proviso is easy to skip.
Fix: A refund after adjusting tax payable out of the section 27 advance tax is claimed only after the last required return has been furnished.
Worked examples
Example 1
Aarav Exports Pvt Ltd, Surat, exports goods under LUT without payment of IGST. During the relevant period: zero-rated turnover of goods ₹90,00,000 (already the lower of the permitted values), Net ITC ₹6,00,000, Adjusted Total Turnover ₹1,50,00,000. There is no zero-rated services turnover. Find the maximum refund under Rule 89(4). What does Rule 89(2) require on unjust enrichment for this claim?
Show the solution
- Formula: Refund = (zero-rated goods + zero-rated services) × Net ITC ÷ Adjusted Total Turnover.
- Substitute: (90,00,000 + 0) × 6,00,000 ÷ 1,50,00,000.
- Calculate: 90,00,000 ÷ 1,50,00,000 = 0.6.
- 0.6 × 6,00,000 = ₹3,60,000.
- The claim exceeds ₹2 lakh, so Rule 89(2)(m) requires an Annexure 2 certificate from a CA or cost accountant that the incidence of tax has not been passed on.
- The provisos to Rule 89(2)(l) and (m) remove this requirement only if the claim falls within clauses (a), (b), (c), (d) or (f) of section 54(8). Rule 89 does not show what those clauses cover, so you must check section 54(8) itself to see whether this claim falls in one of them. If it does, no certificate is needed. If it does not, the certificate is required.
- Under Rule 89(3), the electronic credit ledger is debited by the refund claimed.
Answer: Maximum refund is ₹3,60,000, claimed in FORM GST RFD-01. Because the claim exceeds ₹2 lakh, an Annexure 2 certificate under Rule 89(2)(m) is required unless the claim falls within the listed clauses of section 54(8), to be confirmed from section 54 itself. The electronic credit ledger is debited by ₹3,60,000 under Rule 89(3).
Example 2
Ramesh Traders, a registered person, paid ₹1,40,000 as tax in excess by mistake and wants a refund of the excess tax. Which documents must accompany RFD-01?
Show the solution
- The claim is for excess payment of tax, so Rule 89(2)(k) applies: a statement showing the details of the amount of claim on account of excess payment of tax (and interest or any other amount paid, if any).
- The claim is ₹1,40,000, which does not exceed ₹2 lakh.
- Rule 89(2)(l) therefore requires a declaration that the incidence of tax has not been passed on to any other person.
- No CA/CMA certificate is needed because the amount is within the limit.
- The application is filed electronically in FORM GST RFD-01 on the common portal.
Answer: File RFD-01 electronically with the statement of excess payment under clause (k) and a declaration under clause (l) that the incidence of tax has not been passed on. A certificate under clause (m) is not required.
Exam tips
- MCQs usually test the ₹2 lakh threshold and who gives the document: a declaration by the applicant, a certificate from a CA or cost accountant.
- Learn the clause letters for the main refund types. A case question hides the clause in a keyword such as shipping bill, BRC or SEZ.
- In numerical questions, do the Rule 89(4) or 89(5) calculation first, then test the claim against ₹2 lakh to name the right unjust enrichment document.
- Always write the Rule 89(3) ledger debit when the refund is of ITC. It is an easy mark to add.
- Do not state time limits from memory in this answer. Rule 89(1A) and 89(1B) give two years only for the specific cases they describe.
