Documents Required for GST Refund

Documents Required for GST Refund and Upload Tips

A GST refund application is decided primarily on the strength of its documentation. Even where the amount is legally refundable, an incomplete invoice statement, missing export-realisation proof, unreconciled return data or an unreadable attachment may lead to a deficiency memo, additional queries or rejection of part of the claim.

This guide explains the documents required for GST refund applications filed in FORM GST RFD-01, category-wise supporting evidence, declarations and certificates, and practical tips for uploading files on the GST Portal. The precise document set depends on the refund category, relevant tax period and facts of the case. For end-to-end assistance, visit our GST Refund Services in India page.

What Documents Are Required for a GST Refund?

The document list depends on the refund category

There is no single document checklist for every GST refund. An exporter claiming unutilised input tax credit requires a different evidence set from a taxpayer seeking refund of excess tax, an appellate pre-deposit or tax paid under the wrong head. Before compiling attachments, select the correct refund category on the GST Portal and map each supporting document to that category.

Three layers of GST refund documentation

A complete claim normally contains three layers: information and statements completed online in FORM GST RFD-01; statutory declarations, undertakings or certificates; and supporting evidence such as invoices, shipping documents, bank-realisation records, SEZ endorsements, challans or orders. The figures in every layer should reconcile with GSTR-1, GSTR-3B, GSTR-2B and the electronic ledgers, as applicable.

Legal Framework for GST Refund Documents

Section 54 of the CGST Act

Section 54 of the Central Goods and Services Tax Act, 2017 contains the principal provisions governing GST refunds, including limitation, refund of unutilised input tax credit and the unjust-enrichment principle. In most cases, an application must be filed within two years from the relevant date, subject to the particular statutory rule, exclusions and judicial developments applicable to the claim.

Rule 89 and FORM GST RFD-01

Rule 89 of the CGST Rules prescribes the application and documentary evidence for most refund categories. The applicant files FORM GST RFD-01 electronically and supplies the statements, declarations, undertakings, certificates and supporting documents relevant to the selected category. Taxpayers should also review the current form and portal prompts because system requirements may change.

CBIC Circular 125 and later amendments

CBIC Circular No. 125/44/2019-GST contains the electronic refund procedure and a category-wise document matrix in Annexure-A. It must be read with subsequent clarifications, including Circular No. 135/05/2020-GST and Circular No. 197/09/2023-GST. For example, eligible accumulated-ITC refund claims for tax periods from January 2022 onward are linked to invoices reflected in the applicant’s GSTR-2B, not merely the older GSTR-2A framework.

Common Documents to Prepare Before Filing RFD-01

Refund computation and document index

Prepare a concise covering note stating the refund category, tax period, statutory basis and amount claimed. Add a numbered document index and a clear computation showing the tax-head-wise claim. A good index enables the officer to trace each figure and reduces avoidable correspondence.

Returns and electronic-ledger reconciliation

Reconcile the claim with GSTR-1, GSTR-3B, GSTR-2B, the electronic credit ledger and the electronic cash ledger, as relevant. Explain amendments, debit notes, credit notes, delayed reporting and differences between books and returns. If the underlying returns contain errors, assess whether correction is possible before filing the refund.

Bank account and registration particulars

Select an active bank account associated with the GST registration and ensure that the account details, PAN-linked name and IFSC are correct. Bank-account validation failures can delay disbursement even after sanction. Keep a cancelled cheque, recent bank proof and registration details ready if the portal or proper officer requires clarification.

Documents for Export of Goods Refund

Exports without payment of tax under LUT or bond

For refund of unutilised ITC on export of goods without payment of tax, commonly relevant records include the valid LUT or bond details, export invoices, Statement 3, Statement 3A or the portal-prescribed computation, shipping-bill details, GSTR-1 export data, GSTR-3B figures and inward-supply statement or Annexure-B details. The invoice, shipping bill, port code, taxable value and dates should match across records.

Shipping bills, EGM and non-EDI exports

Confirm that the shipping bill and Export General Manifest or export report have been filed and that Customs data is correctly transmitted. Circular No. 125 specifically refers to uploading the shipping bill for exports through non-EDI ports. For EDI exports, retain shipping bills, bills of lading or airway bills and export evidence for reconciliation and response to any query.

IGST-paid export of goods follows Rule 96

Refund of integrated tax paid on goods exported out of India ordinarily follows Rule 96. The shipping bill is treated as the refund application after the prescribed conditions are met, including filing of the export manifest or report and the relevant GST return data. It is therefore different from a regular RFD-01 claim. Reconcile GSTR-1, GSTR-3B and Customs records through ICEGATE and resolve invoice, port-code, shipping-bill or bank-account mismatches promptly.

Documents for Export of Services Refund

Export invoices, contracts and LUT

Keep export invoices, the service agreement or statement of work, customer details and a valid LUT or bond where services were exported without payment of integrated tax. The documents should help demonstrate that the transaction satisfies the conditions for export of services under the IGST Act, including the place-of-supply and recipient-location requirements.

BRC, FIRC and proof of receipt

Upload the Bank Realisation Certificate, Foreign Inward Remittance Certificate or another permitted banking document evidencing receipt of export proceeds. Where consideration is received in Indian rupees as permitted by the Reserve Bank of India, retain the banking trail and the basis supporting such receipt. Map every receipt to the relevant export invoice and identify partial realisations.

Statement 2 or Statement 3 and refund computation

Use the statement applicable to the selected category: Statement 2 is relevant to tax paid on export of services, while Statement 3 and the associated computation apply to eligible unutilised-ITC claims for zero-rated supplies without payment of tax. Reconcile invoice values, realised turnover, adjusted total turnover and net eligible ITC with the returns and books.

Documents for Supplies to SEZ Units or Developers

Tax invoices and SEZ endorsement

Obtain tax invoices and the endorsement of the specified SEZ officer confirming receipt of goods or services for authorised operations. The endorsement should be legible and should clearly correspond with the invoice. Missing or generic endorsements are a frequent reason for objections in SEZ refund claims.

Statements for supplies with or without payment of tax

Prepare Statement 4 for tax-paid supplies to an SEZ unit or developer and Statement 5 or 5A, as applicable, for supplies without payment of tax and the related unutilised-ITC computation. Reconcile the claim with GSTR-1, GSTR-3B, invoices, e-way bills or delivery evidence and the recipient’s confirmation.

Declarations to prevent duplicate benefit

Keep the declarations required by Rule 89 and the portal ready, including evidence concerning non-passing of tax incidence where applicable. Where the supplier files the refund, obtain appropriate confirmation that the SEZ recipient has not claimed the same refund and deal correctly with any ITC availed by the recipient.

Documents for Inverted Duty Structure Refund

Statement 1, Statement 1A and Annexure-B

Prepare the portal-prescribed Statement 1 and Statement 1A together with inward-invoice details in Annexure-B or the current utility format. Include HSN or SAC information and clearly distinguish inputs, input services and capital goods. The refund formula and eligible credit should be applied in accordance with the law governing the relevant period.

GSTR-2B and eligible ITC reconciliation

For tax periods from January 2022 onward, reconcile the claim with eligible invoices reflected in GSTR-2B for the relevant or earlier tax periods, subject to the conditions of Section 16. Remove blocked credit and other ineligible amounts. For inverted-duty refunds, input services and capital goods do not form part of Net ITC under the prescribed formula.

Input-output rate and turnover evidence

Prepare an HSN-wise comparison of the GST rate on inputs and the output supplies, along with product descriptions, turnover workings and relevant rate notifications. A claim arising merely from a reduction in the rate on the same goods requires careful eligibility review under the clarification in Circular No. 135/05/2020-GST.

Documents for Deemed Export Refund

Documents for a supplier’s claim

A supplier claiming refund of tax paid on deemed exports should prepare Statement 5B, evidence that the supply qualifies as a deemed export, acknowledgement or other prescribed recipient evidence, tax invoices and the documents required under Notification No. 49/2017-Central Tax and Circular No. 14/14/2017-GST. The applicant should also establish that the recipient has not availed the same benefit contrary to the prescribed conditions.

Documents for a recipient’s claim

A recipient’s deemed-export refund claim should include Statement 5B, eligible supply documents and the declarations or undertakings prescribed for the category. Maintain evidence of payment of tax to the supplier and of non-availment or reversal of input tax credit, wherever required, so the same tax is not refunded twice.

Documents for Other GST Refund Categories

Excess cash balance or excess tax payment

For refund of excess balance in the electronic cash ledger, the portal ledger is the primary record and extensive supporting documents may not ordinarily be necessary. For excess payment of tax, prepare Statement 7, challans, returns, tax ledgers, invoice-level reconciliation and a clear explanation showing how the excess arose.

Wrong tax paid on intra-State or inter-State supply

Where CGST and SGST were paid on a transaction later held to be inter-State, or IGST was paid on a transaction later held to be intra-State, prepare Statement 6, original and corrected invoices, proof of tax paid under both treatments, returns, ledgers and the legal or factual basis for correcting the place of supply. The claim should not result in double benefit.

Refund arising from an order or another ground

For refund arising from assessment, provisional assessment, appeal or another order, upload the complete order, its reference number and proof of the original payment or pre-deposit. For an application under “Any Other” ground, provide a reasoned note, computation and all primary evidence establishing the amount, legal entitlement and absence of duplicate refund.

Declarations, Undertakings and Certificates

Declarations relating to Section 54

Complete the declarations appearing in RFD-01 that apply to the selected category, including declarations under the provisos to Section 54(3). Do not upload a generic declaration without checking whether it matches the refund ground, tax period and statutory language currently appearing on the portal.

Undertaking relating to Section 16(2)(c)

The electronic refund process includes an undertaking concerning compliance with Section 16(2)(c). Circular No. 197/09/2023-GST updated the language after omission of Section 42 and changes to the return-matching framework. Use the current portal wording and avoid relying on an obsolete template that still refers to omitted provisions.

Unjust-enrichment declaration or CA/CMA certificate

Where the unjust-enrichment requirement applies, Rule 89 generally requires a self-declaration when the refund claimed does not exceed ₹2 lakh and a certificate from a Chartered Accountant or Cost Accountant when it exceeds ₹2 lakh. The requirement does not apply in the same manner to refund categories covered by Section 54(8). Determine applicability before obtaining or uploading a certificate.

RFD-01 Statements and Data Reconciliation

Use the statement generated for the selected category

The GST Portal activates statements according to the refund ground. Common statements include Statement 1 and 1A for inverted duty, Statement 2 for export of services with payment of tax, Statement 3 and 3A for specified zero-rated claims, Statements 4 and 5 for SEZ supplies, Statement 5B for deemed exports, Statement 6 for wrong tax and Statement 7 for excess payment.

Match invoice-level data before upload

Validate GSTINs, invoice numbers, invoice dates, taxable values, tax amounts, shipping bills, BRC or FIRC references and HSN or SAC codes. Standardise invoice-number formats and investigate duplicates. A spreadsheet may total correctly yet fail portal validation because one character differs from the return or Customs record.

Reconcile books, returns and supporting evidence

Prepare a reconciliation bridge from the books to the GST returns and from the GST returns to the refund claim. Identify excluded ITC, blocked credit, capital goods, input services, amendments and timing differences. Reliable return preparation is essential; our GST Return Filing Services team can assist with return and refund-data reconciliation.

GST Portal File Upload Requirements

Number and size of attachments

Circular No. 125/44/2019-GST states that four supporting documents, each up to 5 MB, may be uploaded with the refund application. Because portal functionality and permitted formats may be updated, always follow the live upload instructions displayed for the relevant RFD-01 category. Where files are limited, create indexed and searchable consolidated PDFs without sacrificing readability.

Readable scans and accepted file formats

Use the file format accepted by the live GST Portal. Scan at a resolution that keeps invoice numbers, signatures, endorsements and bank references readable after compression. Avoid password protection, corrupted files, blank pages, sideways pages and photographs with shadows or cropped edges.

Use safe and descriptive file names

Use short file names with letters, numbers, hyphens or underscores, such as “01_Refund_Computation.pdf” and “02_Export_Evidence.pdf”. Avoid unusual symbols, very long names and vague labels such as “scan1”. Keep the file name consistent with the document index.

How to Organise GST Refund Attachments

Create one indexed PDF for each evidence group

Group documents logically: legal note and computation; returns and ledger reconciliation; outward-supply or export evidence; and inward-invoice or other supporting evidence. Add a cover index and bookmarks where possible. Do not combine documents in random chronological order.

Use cross-references in the covering note

For each material claim, cite the attachment number and page number. For example, link the zero-rated turnover in the computation to the invoice statement, shipping records and return reconciliation. Cross-referencing helps the officer verify the claim without repeatedly seeking clarification.

Retain a complete filing archive

Save the final RFD-01, ARN, uploaded attachments, electronic-ledger debit, acknowledgement, deficiency memo, notices, replies and orders in one case folder. Preserve the editable workings separately. This archive is important for refiling after RFD-03, replying to RFD-08, pursuing an appeal or supporting a future GST assessment or litigation matter.

Common GST Refund Documentation Mistakes

Choosing the wrong refund category

The document fields, statements and legal tests flow from the category selected. A claim filed under “Any Other” when a specific category exists may invite queries or incorrect processing. Determine the legal ground first and then compile the category-specific evidence.

Uploading unreconciled or obsolete documents

Do not rely mechanically on an old checklist referring only to GSTR-2A or superseded undertaking language. Use GSTR-2B where mandated for the relevant period and apply later circulars that modify Circular No. 125. Confirm that returns, portal utilities and attachments relate to the same tax period.

Submitting unclear, incomplete or oversized files

Unreadable scans, missing annexures, unsigned certificates, incomplete bank evidence and files exceeding the portal limit can prevent proper verification. Open every final attachment before submission, search key invoice numbers, check page orientation and confirm that every indexed page is present.

Frequently Asked Questions on GST Refund Documents

Is a covering letter mandatory for a GST refund?

A covering letter is not a substitute for the prescribed form or statement and may not be mandatory in every case. However, a concise factual and legal note with an attachment index is strongly advisable for complex or high-value claims.

Are copies of all purchase invoices required?

Not automatically in every refund claim. Upload the invoice statement and documents required for the selected category and period. Keep the complete invoice set ready for verification, and upload specific copies where the rules, circulars, portal or proper officer validly requires them.

Is GSTR-2A or GSTR-2B relevant for an ITC refund?

For accumulated-ITC refund claims relating to tax periods from January 2022 onward, Circular No. 197/09/2023-GST links eligibility to invoices reflected in GSTR-2B for the relevant or previous tax periods, subject to ITC eligibility. Older periods must be examined under the law and clarifications applicable to those periods.

Is BRC or FIRC required for export of goods?

BRC or FIRC is primarily relevant to proving receipt of consideration for export of services. It is not ordinarily part of the standard RFD-01 document requirement for export of goods under Circular No. 125, although foreign-exchange and export laws may separately require realisation and evidence.

Can additional documents be submitted after filing RFD-01?

The officer may seek clarification or issue the applicable notice, and the taxpayer can respond through the prescribed portal process. It is better to file a complete application initially because missing core documents may result in a deficiency memo and require a fresh application.

What happens if FORM GST RFD-03 is issued?

RFD-03 is a deficiency memo identifying defects in the application. The applicant should correct the deficiencies and file a fresh refund application in accordance with the applicable procedure. Review limitation immediately and retain the original ARN, memo and corrected document set.
