Most GST Portal failures are recoverable once you identify the stage that failed. A Processed with Error upload needs the portal’s error report and a corrected file from the current Returns Offline Tool. File could not be uploaded usually means the JSON does not pass the current GSTR-1 schema. Missing invoices, signing failures and a return stuck in progress require different fixes.
Use the exact message below, correct the underlying data or local setup, regenerate rather than hand-editing generated JSON, and retry only after the portal’s stated processing interval.
Identify the failure stage first
The same invoice can appear to fail for different reasons depending on when GSTN rejects it. Use this map before changing data:
| Portal message or symptom | Failure stage | First action |
|---|---|---|
Processed with Error |
Portal processed the upload and rejected specific rows | Download the error report, fix every listed row in the current offline tool, regenerate JSON |
File could not be uploaded |
File transfer or JSON/schema validation | Validate the JSON against the current GSTR-1 schema and regenerate it |
Enter valid GSTIN/UIN |
Identity or field-format validation | Check the GSTIN/UIN characters, structure and logged-in taxpayer |
| Invoices uploaded but not visible in the tile | GSTR-1 summary generation and background processing | Generate the GSTR-1 Summary once, then allow processing time |
| DSC authentication or emSigner error | Signing and certificate authentication | Match the PAN, authorized signatory, certificate and connected token |
Your previous GSTR3B filing request is still in progress |
Duplicate or pending nil-filing request | Wait at least 10 minutes, reopen the period and restart the nil-filing flow |
GST Portal labels, offline-tool releases, schemas and validations change. Check the latest GSTN advisory and tool version on the day you troubleshoot, especially for a return period affected by a recent rule change.

Fix “Processed with Error” uploads
This status means GSTN accepted the file for processing but found one or more invalid records. The original upload is not a usable return file until those rows are corrected.
Download and use the error report
- Open the relevant upload history on the GST Portal after processing has completed.
- In the Error Report column, select Generate error report.
- Allow about 15 minutes for the link to become available. GSTN’s Returns Offline Tool guide says the report is downloaded as a ZIP file.
- Open the ZIP directly in the current Returns Offline Tool. Do not type changes into the generated JSON in a text editor.
- Read every row and error description, correct the source data in the tool, and save the corrected worksheet or section.
- Use the tool’s JSON-generation option to create a new file, upload that file, and check the new status.
Fix all listed rows in one pass where possible. Uploading the same defective JSON repeatedly only creates more failed attempts and can make it harder to tell which version is current.
When the report itself is unavailable
If processing has only just finished, refresh the upload history later rather than uploading again immediately. If the link still does not appear after the approximate availability period, record the return period, upload timestamp and status, then escalate with a screenshot and the original downloaded file.
Fix “File could not be uploaded”
This message normally occurs before row-level processing. Treat it as a file-integrity or schema problem first, not as proof that an individual invoice is commercially invalid.
Validate against the current schema
- Download the latest GSTR-1 offline tool and the current GSTR-1 JSON schema referenced by GSTN’s developer documentation.
- Run the JSON through a validator that checks that schema. A validator can expose a missing required property, an invalid data type or a malformed section before the portal receives the file.
- Review the validator path and row number. For example, GSTN’s known-issues procedure cites a missing UQC (Unit Quantity Code) in an HSN section as a required-property error.
- Return to the source row in the offline tool, enter the required value using the tool’s accepted format, and save it.
- Generate a fresh JSON from the tool and upload that new file.
Never patch a generated JSON blindly. A manual edit can make the file syntactically valid while leaving the offline tool’s internal calculations or related fields inconsistent. Correct the source record and regenerate.

Basic file checks
- Use the file produced by the current tool, not an older export saved from a previous schema version.
- Keep the original extension and file structure created by the tool; do not rename a spreadsheet or ZIP as JSON.
- Remove accidental blank records, unsupported characters and truncated values in the source data.
- Regenerate after every correction so the upload contains the latest changes.
Correct GSTIN, UIN and invoice-date validation
Match the supplier GSTIN to the login
The supplier GSTIN in the upload must be the GSTIN of the taxpayer account currently logged in. A file prepared for one registration and uploaded while another registration is selected can fail even when every invoice is otherwise correct. Confirm the GSTIN shown in the portal header and compare it character by character with the supplier field in the offline tool.
The message Enter valid GSTIN/UIN can indicate an invalid value or structure. Check the number of characters, letter and digit positions, and whether a UIN was entered in a field that expects a GSTIN. Correct the source field and regenerate the JSON.
Recommended Free Tools
Check the registration date
GSTN rejects an invoice date earlier than the supplier’s GST registration date. Compare the invoice date with the registration effective date shown for that GSTIN. If the date is wrong in the source document, correct the document and the tool record. If the transaction genuinely predates registration, it cannot be reported as an invoice issued under that GST registration; obtain professional tax advice on the appropriate treatment instead of forcing the upload.
Check period and date formats together
Make sure the invoice belongs to the selected return period and that the offline tool has interpreted the date as a date rather than text. A spreadsheet that displays a familiar date can still export an invalid value if the cell contains hidden text or an unsupported format. Re-enter the date using the tool’s date control, save, and regenerate.
Remove duplicates and repair amendments
Duplicate supply invoices
GSTR-1 does not accept duplicate supply invoices. Before retrying, search the upload history and the relevant GSTR-1 section for the invoice number, financial year, document type and recipient details. Remove the duplicate record from the source data; do not alter an invoice number merely to bypass the rejection.

“Original Invoice cannot be tracked”
An amendment must point to an original invoice that GSTN can find. Search the relevant earlier-period data using the original invoice number, date, recipient GSTIN and document type. If the original was never uploaded, upload the original first and wait until it is searchable. Then prepare the amendment against that exact original reference and regenerate the JSON.
If the original exists but the amendment still fails, compare every reference field with the searchable original. A changed invoice number, date, recipient GSTIN or document type can make a valid original appear untraceable.
Invoices uploaded but not showing in GSTR-1
Successful file transfer does not immediately guarantee that the GSTR-1 tile counts or summary reflect the records. GSTN separates upload processing from summary generation.
Generate the summary once
- Open the relevant GSTR-1 return period.
- Scroll to the bottom of the page.
- Select GENERATE GSTR1 SUMMARY.
- Wait for the request and background processing to complete, then refresh the return.
GSTN guidance limits repeated summary requests: a second request within 10 minutes can produce an error. Do not click the button repeatedly or upload the same invoices again while the first request is processing.

Verify whether the issue is display or processing
- Check upload history for a successful status rather than relying only on the tile count.
- Confirm that the invoices were uploaded under the same GSTIN, financial year and return period now open.
- Allow the portal’s automatic processing time before concluding that records are missing.
- If the count remains wrong after processing, capture the upload reference, period, section and screenshots for GSTN support.
Resolve DSC, emSigner and EVC filing failures
DSC prerequisites
GSTN’s GSTR-1 FAQ states that the portal accepts PAN-based digital signature certificates (DSCs) only. The certificate must also be registered on the GST Portal, unexpired and associated with the authorized signatory selected for filing.
- Confirm that the selected authorized signatory’s PAN matches the PAN embedded in the certificate.
- Check the certificate validity date and renew or replace an expired certificate.
- Register the certificate for the correct GSTIN if it has not been registered there.
- Install the emSigner version required by the current GST Portal instructions.
- Connect the actual DSC token or dongle before starting authentication; a generic USB storage drive is not a DSC token.
- Close conflicting signing utilities and restart emSigner if the portal cannot detect it.
Authentication error RT-3BAS1031
GSTN’s known-issues guidance associates Authentication has failed at emas (RT-3BAS1031) generally with a certificate linked to a different PAN from the selected signatory. Select the signatory whose PAN matches the certificate, choose the matching certificate when prompted, and retry.
Use EVC when the filing permits it
Electronic Verification Code (EVC) is an alternative where the return and taxpayer category allow it. GSTN sends the OTP to the authorized signatory’s registered email address and mobile number. Ensure both contacts are accessible, use the newest OTP, and enter it before it expires. EVC does not repair a data or schema error; it only changes the authentication method.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Clear a GSTR-3B request that is still in progress
The message Your previous GSTR3B filing request is still in progress usually means the portal has not finished the earlier nil-filing request. GSTN advises waiting at least 10 minutes before retrying the entire nil-filing process.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Do not submit the nil return repeatedly while the first request is pending.
- Wait at least 10 minutes.
- Return to the Returns Dashboard.
- Select the financial year and return period again.
- Restart the complete nil-filing flow and authenticate once.
If the message persists after the waiting period, record the period, GSTIN, time of the first attempt and any reference number. Escalate that evidence rather than creating parallel submissions.

Handle IFF and e-invoice validation errors
IFF “Error in submission”
For an Invoice Furnishing Facility (IFF) submission, GSTN indicates that the error can occur when the cumulative reported value exceeds the applicable limit. Remove enough records to bring the period within the limit and report the remaining eligible records in the next permitted period. Preserve the invoice list and amounts so the deferred records are not lost.
Invalid HSN and other e-invoice errors
Recheck the HSN code against the current Invoice Registration Portal (IRP) validation rules. The IRIS IRP troubleshooting page identifies invalid HSN code error 2176. Correct the code in the source invoice and regenerate the e-invoice payload; do not substitute a similar-looking code without confirming the classification.
30-day reporting window for larger taxpayers
IRIS IRP records that taxpayers with aggregate annual turnover (AATO) of ₹10 crore or more must report e-invoices within 30 days of the invoice date from 1 April 2025. This is a date-based rule, so an invoice that was valid under an earlier process can fail when submitted late under the current requirement. Confirm the taxpayer’s AATO category and the rule applicable to the invoice date.

IRIS IRP also records a February 2026 relaxation for specified RSP-based value validations. Because the relaxation applies only to specified cases and may be revised, check the current IRP advisory before changing a value that appears inconsistent with the older validation rule.
Escalate efficiently when the correction does not work
Support can diagnose a reproducible error much faster when the submission history is complete. Prepare:
- GSTIN of the logged-in taxpayer and, where relevant, recipient GSTIN
- Financial year, return period and form or section
- Exact portal message and numeric error code
- Upload timestamp, reference number and current status
- Downloaded error-report ZIP or validator output
- Offline-tool version and schema version used
- Screenshot showing the page and message, with unnecessary personal data redacted
- Whether the failure occurred during JSON generation, upload, processing, summary generation, signing or final submission
Use GSTN’s official help and advisory channels for GST Portal problems and the relevant IRP support channel for e-invoice errors. Do not send private keys, DSC PINs, OTPs or complete customer databases in a support ticket.
Quick Recap
Prevent the most common repeat failures
- Download the current offline tool and schema before preparing each return cycle.
- Keep the GST registration effective date and all active GSTINs in the accounting master data.
- Use a duplicate check on invoice number, financial year, document type and recipient GSTIN before export.
- Maintain a link between every amendment and its original invoice reference.
- Validate required fields such as UQC before generating JSON.
- Keep one untouched source file and one clearly named corrected version for each upload attempt.
- Generate the GSTR-1 Summary only when needed and wait for the portal’s processing interval.
- Check DSC expiry, PAN association, signatory registration and emSigner before the filing deadline.
- Record upload references and error reports until the return is accepted and the summary is visible.
