A GSTR-1 JSON error occurs when there is an issue with the data structure of your GSTR-1 filing in JSON format. This can happen during the upload of invoice details to the GST Portal, causing the status to change to 'Processed with Error.' Common issues include incorrect GSTINs, invalid invoice dates, and duplicate invoices. Understanding these errors is crucial for correcting them efficiently, allowing for a smoother GST filing process. By following the right validation steps before submission, you can significantly minimize these errors.

To validate your invoices, start by clicking on 'Validate data before Upload' in the GST Portal. This action will automatically generate a report which you can download. Open this report to identify any invoices with errors, as it categorizes them based on the nature of supply. Each error will have a clear explanation along with suggested corrective actions. After addressing the issues, revalidate your invoices by repeating the process. Once no errors are reported, you can confidently proceed to upload your data.

Error RET191106 indicates there is an issue with the JSON structure validation, specifically that the GSTIN provided in the CT GST is incorrect. To resolve this, double-check the GSTIN listed in your invoice against the correct GSTIN to ensure accuracy. Make the necessary corrections in your JSON file, then revalidate your invoices. Once confirmed that the error is rectified, you can proceed with your GSTR-1 upload. Staying attentive to GSTIN details is essential to avoid such issues.

Error RET191113 arises when an invalid GSTIN for the customer is entered. To fix this issue, download the JSON report that highlights this specific error. Find the relevant invoice in the report and correct the customer's GSTIN to a valid one. It’s crucial to verify the GSTIN from a reliable source or the customer's documentation. After making the correction, revalidate your invoices to ensure that the error is resolved before uploading your GSTR-1 again.

If you encounter an error stating that the invoice date cannot precede the registration date (like RET191114), you need to address it by adjusting the invoice details. First, move the affected invoices to the B2C(S) section and remove the customer's GSTIN from those invoices. Next, recalculate the B2C(S) summary to ensure accuracy. After making these changes, revalidate your data to confirm there are no more errors. Once everything checks out, you can proceed with the upload.

A duplicate invoice error (RET191133) indicates that the system has detected invoices with the same invoice number and either the same or different CTINs. To resolve this, check if the same invoice has already been uploaded. If the invoice remains unchanged, you can disregard the error. However, if you need to upload a revised invoice, ensure to delete the old entry first before re-uploading the new one. Keeping a well-organized invoice record can help prevent such issues.

If you get the error indicating that there is no section data or gross turnover available (RET191148) while filing a NIL return, ensure that you are following the correct filing procedures for NIL returns. Check the guidelines provided by the GST portal to confirm that you have populated all necessary details. If you're specifically filing a NIL return, refer to additional resources or guides on how to file NIL returns effectively. This will help ensure your submission is compliant and free from errors.

To ensure that the rates entered in your GSTR-1 are valid, you should cross-check them against the official GST rate list provided by the government. If you encounter error RET191175 indicating that the rate entered is not valid, it’s important to review the applicable rates based on the type of supply you are dealing with. Adjust the rates accordingly and ensure they align with the latest updates on GST rates. This validation step is crucial for compliance and to avoid delays in your filing process.

If you encounter the decryption/decoding failed error (RET191166), it may indicate an issue with the JSON file format or data integrity. In this case, it’s best to reach out for support. You can contact the help desk at gst-json-errors@cleartax.in for assistance. Provide them with the details of your issue, and they can guide you on how to resolve it. Always ensure that your JSON files are correctly structured and validated before attempting to upload them to minimize such errors.
