Documents for GST Refund

Tips for Uploading Documents at the Time of GST Refund – 2026 Guide

Uploading the correct documents for GST refund is an important part of filing a refund application under the Goods and Services Tax law in India. Businesses claiming GST refunds through FORM GST RFD-01 must submit the relevant declarations, statements, invoices and supporting evidence according to the refund category.

Incorrect attachments, unreadable invoices, oversized PDF files, mismatched invoice details or incomplete supporting statements may result in deficiencies, departmental clarification notices and delays in processing a GST refund.

Important 2026 update: The official GST Portal guidance permits taxpayers to upload up to 10 supporting documents, each not exceeding 5 MB, with a combined maximum of 50 MB, for relevant GST RFD-01 applications and RFD-09 replies. Earlier guidance referring to four files and 20 MB should not be relied upon without checking the current portal requirements.

This guide explains GST refund document requirements, PDF scanning and compression, file naming, document preparation, upload procedures, common errors and practical checklists for exporters, businesses claiming accumulated ITC and other refund applicants.

EzyBiz India Consulting LLP provides GST refund advisory, document verification, refund application preparation, reconciliation and departmental clarification support for Indian and foreign-owned businesses.

GST Refund Documents Upload – Overview

Why Are Supporting Documents Required?

Supporting documents help establish the legal basis, eligibility and amount of the refund claimed under Section 54 of the CGST Act and the applicable refund rules.

They may substantiate tax payments, export transactions, eligible input tax credit, invoices, refund calculations and other facts relevant to the application.

What Is FORM GST RFD-01?

FORM GST RFD-01 is the prescribed electronic application used for several categories of GST refund.

Depending on the refund type, the taxpayer must provide relevant information, declarations, prescribed statements and supporting documents through the GST Portal.

Why Do GST Refund Uploads Fail?

Upload failures may arise because of excessive file size, unsupported formats, unreadable documents, incorrect statements or technical validation errors.

Applicants should complete both documentary and tax reconciliations before attempting submission.

GST Refund Document Upload Limits in 2026

Maximum Number of Supporting Documents

The official GST Portal’s published scanning guidance provides for uploading up to 10 supporting documents with relevant GST RFD-01 refund applications and RFD-09 replies.

The actual upload fields and permitted documents should be checked in the refund category selected on the portal.

Maximum File Size of 5 MB

Each supporting document can be up to 5 MB, subject to the current GST Portal specifications.

Accordingly, the published combined upload capacity is 50 MB for 10 files.

Why Older Articles Mention Four Documents

CBIC Circular No. 125/44/2019-GST referred to four supporting documents of 5 MB each under the electronic refund process at that time.

Subsequently, the GST Portal’s published guidance provides for 10 documents. Applicants should use the currently applicable portal requirements rather than outdated limits.

Documents Required for GST Refund Applications

Common GST Refund Supporting Documents

The documents required depend on the particular refund category. Relevant records may include:

• Refund application details
• Tax invoices and debit or credit notes
• Supporting invoice statements
• Tax payment and ledger records
• Relevant GST return details
• Export or SEZ documentation
• Refund computation statements
• Applicable declarations and certificates
• Orders resulting in refund eligibility
• Bank account and payment information

Documents Differ by Refund Category

The requirements for export-related refunds differ from those for inverted duty structure, excess tax payment, electronic cash ledger balances or refunds arising from appellate orders.

Rule 89 and the relevant notifications, circulars and portal instructions should be reviewed for the exact category.

Check the Required Statements and Annexures

Before uploading attachments, determine whether the application requires Statement 1, Statement 3, Statement 3A, Statement 5 or another prescribed statement or annexure.

Not all refund applications require the same statements, and some information may be entered directly into the applicable online form or uploaded using prescribed templates.

Our GST Refund Services cover eligibility review and refund documentation assistance.

How to Scan GST Refund Invoices and Documents

Select Appropriate Scanning Resolution

The official GST Portal scanning guide recommends a low scanning resolution, including around 100 DPI, as a method of controlling PDF file size.

However, if such a resolution makes invoice numbers, GSTINs, tax amounts or other relevant information difficult to read, use a higher resolution that maintains legibility.

Use Grayscale for Suitable Documents

Grayscale or black-and-white scanning can reduce file sizes for text-based invoices, statements and ordinary business documents.

Retain colour where it is necessary to understand the document or preserve material information.

Convert Multiple Scans into One PDF

Where several invoices support the same refund application, they may be combined into a single organised PDF within the applicable file-size limit.

Arrange documents chronologically or by invoice number so the refund officer can locate the relevant evidence.

How to Reduce PDF Size for GST Refund Upload

Compress PDF Files without Losing Readability

Use a reputable PDF compression or optimisation tool to reduce the size of scanned files.

After compression, verify that all figures, invoice references, dates, signatures and GSTIN details remain readable.

Remove Unnecessary Blank Pages

Review the document and remove blank pages, repeated scans, unnecessary cover sheets and unrelated materials.

This helps reduce file size and improves the quality of the supporting documents.

Split Oversized Documents into Logical Files

If a PDF exceeds the 5 MB limit, divide it into clearly named sections where appropriate.

For example, export invoices may be grouped by month or invoice-number range, provided the complete evidence remains available.

Combining Invoices, Debit Notes and Credit Notes

How Many Invoices Can Be Included in One PDF?

The GST Portal’s published guidance does not impose a separate fixed number of invoices within one supporting scanned document.

The practical restriction is the applicable file size, document readability and the upload requirements for that refund category.

Arrange Invoices in a Consistent Order

Use a consistent arrangement, such as invoice date, financial year, customer or invoice number.

The order should correspond, as far as practicable, with the relevant refund statement or reconciliation.

Keep Credit and Debit Notes Traceable

Where credit notes or debit notes affect the refund computation, preserve the connection between the original invoices and subsequent adjustments.

Ensure that the documentary evidence and claim calculation remain consistent.

Step-by-Step GST RFD-01 Document Upload Process

Step 1 – Login and Select the Refund Category

Visit the official GST Portal and log in using the applicable credentials.

Navigate to the refund application facility and select the appropriate refund category.

Step 2 – Complete Statements and Upload Documents

Enter the required refund information, prepare the prescribed statements and upload the relevant supporting documents in the available attachment fields.

Confirm that the documents match the amount and period claimed.

Step 3 – Verify and Submit the Application

Review the application before final submission, including the bank account details, declarations and electronic ledger amounts where applicable.

Submit the application using the prescribed authentication method and preserve the Application Reference Number generated after successful filing.

The detailed eligibility and filing assistance is available through our GST Refund Consultancy Services.

GST Refund Documents for Exporters

Documents for Export of Goods

Refund applications involving the export of goods may require export invoice details, shipping bill or bill of export particulars and other evidence prescribed for the selected refund category.

The exact documentation differs according to whether the refund concerns integrated tax paid on exports or accumulated ITC on zero-rated supplies without payment of tax.

Documents for Export of Services

Export-of-services refunds may require invoices, details of receipt of consideration, relevant Bank Realisation Certificates or Foreign Inward Remittance Certificates, and prescribed refund statements.

Applicants should also verify that the transactions satisfy the legal conditions for export of services.

Reconcile Export Documents with GST Returns

Reconcile export invoices, GSTR-1, GSTR-3B, books of account and supporting banking or customs records before claiming the refund.

Differences in invoice numbers, values and relevant tax periods should be investigated.

Read our GST Refund Difficulties Faced by Exporters guide.

GST Refund Documents for SEZ and Deemed Exports

Supplies to SEZ Units and Developers

GST refunds involving supplies to SEZ units or developers require compliance with applicable zero-rated supply provisions and prescribed documentary evidence.

Relevant records may include invoices, endorsement evidence and other applicable statements and declarations.

Documents for Deemed Export Refunds

Deemed export refunds require the applicant to establish that the supplies qualify under the relevant notification and that the applicable claimant conditions are satisfied.

Invoices and prescribed declarations or undertakings may be required.

Verify the Correct Applicant and Refund Category

Before filing an SEZ or deemed export refund, identify who is entitled to make the claim and which refund category applies.

An incorrect applicant category or missing required undertaking may create an avoidable compliance problem.

Documents for Inverted Duty Structure GST Refund

Input and Output Tax Rate Comparison

Where accumulated ITC is claimed because the rate of tax on eligible inputs exceeds the rate on relevant output supplies, the applicant should examine Section 54(3), Rule 89 and applicable restrictions.

Not every accumulated ITC balance qualifies for an inverted duty structure refund.

Purchase Invoice and ITC Reconciliation

Relevant records may include purchase invoices, outward supply details, GST return information and ITC reconciliation statements.

The applicant should identify eligible ITC for the prescribed refund computation and exclude ineligible amounts.

Supporting Refund Computation

Prepare the relevant refund computation according to the statutory formula and refund period.

Ensure that the information entered in the application is consistent with the supporting accounting and tax records.

GST Refund Documents for Excess Payment and Cash Ledger

Excess GST Payment Documentation

Where a refund arises from excess tax payment, the taxpayer should prepare evidence showing the tax originally paid and the actual amount legally payable.

Depending on the facts, supporting records may include challans, ledger statements, returns and reconciliation workings.

Electronic Cash Ledger Refund

Refund of an eligible electronic cash ledger balance is subject to its own statutory and portal requirements.

The taxpayer should verify the available balance, correct tax head and bank account details before submitting the claim.

Avoid Reusing the Same Evidence Incorrectly

Each application should clearly establish the particular refundable amount.

Do not claim the same tax payment or ledger balance more than once through different refund applications.

Documents for Refund Based on Assessment or Appeal Orders

Upload the Relevant Order

Where a refund becomes due as a consequence of an assessment, provisional assessment, appellate or other eligible statutory order, upload the relevant order and supporting details.

Ensure that the order relates to the correct GSTIN, tax period and claimed amount.

Match Refund with Tax Payments

Prepare a reconciliation between the original demand or tax payment, subsequent order and amount eligible for refund.

Additional documents may be required based on the specific refund ground and proceedings.

Maintain an Order-Wise Working

Where several orders or tax periods are involved, maintain separate workings to avoid duplicate claims and unsupported amounts.

For related legal proceedings, visit our GST Assessment and Litigation Services.

How to Upload Supporting Documents in GST RFD-09

What Is FORM GST RFD-09?

FORM GST RFD-09 is used for responding to a show cause notice issued in the refund proceedings through FORM GST RFD-08.

The taxpayer should address the issues raised and provide relevant documentary evidence.

Document Upload Limit for RFD-09 Replies

The GST Portal’s published scanning guidance covers RFD-09 replies and permits up to 10 documents of 5 MB each, subject to the current portal requirements.

Applicants should check the actual available upload fields when preparing the response.

Prepare a Point-Wise Reply with Annexures

Prepare the written response and arrange supporting documents in an order that corresponds with each objection in the notice.

Use a document index to help the officer identify the specific evidence relied upon.

Common GST Refund Upload Errors and Solutions

PDF Exceeds the Permitted File Size

Compress the file, reduce unnecessary image resolution or divide the evidence into suitably labelled documents.

Do not omit material evidence merely to satisfy the size limit.

Unreadable Invoice or Incorrect Attachment

Check each uploaded document in its final form before submission.

Replace blurred scans, rotated pages and incorrect files with legible and relevant versions.

Mismatch in Statements and Supporting Documents

Invoice numbers, dates, taxable values and tax amounts should be reconciled with the prescribed statements and accounting records.

Where differences are identified, resolve them before submitting the application or provide an appropriate explanation if legally required.
