When filing GSTR-1, you may encounter several common JSON errors. Some of the most frequent ones include RET191106, which indicates a JSON structure validation failure, and RET191113, which signifies an invalid GSTIN. Other errors like RET191114 point to specified dates being invalid, while RET191115 indicates that the invoice number does not exist in the system. Understanding these errors and their meanings is crucial for rectifying them efficiently. Each error typically comes with a specific solution, so it's key to refer to the JSON report for guidance.

To minimize JSON errors when filing GSTR-1, you should validate your data beforehand. Start by selecting the option to 'Validate data before Upload' on the GST Portal. This will generate a report highlighting any issues with your invoice data. Take time to examine this report; it will categorize errors and suggest corrective actions. Once you've made the necessary adjustments, validate your data again to ensure all errors have been resolved before the final upload. This proactive approach can save you time and frustration later on!

If you come across error RET191106, it indicates that the JSON structure validation has failed. This is often due to incorrect information in the CT GST section. To resolve this issue, double-check that the GSTIN entered is accurate and matches the corresponding details in your invoices. Make the necessary corrections and then revalidate your data before attempting to upload again. This step is crucial to ensure compliance with GST regulations and to avoid further complications in your filing process.

Error RET191150 indicates that IGST is mandatory for interstate transactions. This means that if your transaction crosses state lines, you must charge Integrated Goods and Services Tax (IGST) instead of CGST and SGST. To fix this error, review the tax rates applied to your invoices. Ensure that you are applying IGST for all applicable interstate transactions. Once you've made the necessary adjustments to your tax calculations, you can proceed with the upload. Remember, accurate tax application is vital for compliance.

Error RET191148 indicates that there is missing section data or gross turnover information in your submission. To resolve this, go back to your invoices and ensure that all necessary details are filled in. This includes verifying that gross turnover information is accurately reported and that no sections are left blank. After correcting these details, validate your data again to confirm that all issues have been addressed before re-uploading your GSTR-1. This attention to detail helps maintain compliance and ensures a smoother filing experience.

If you encounter error RET191115, it suggests that the invoice number you provided does not exist in the system. To resolve this issue, first, check the format of your invoice number; it should not exceed 16 characters. Make sure that the invoice number matches exactly what is recorded in your accounting software or documentation. If the invoice number is correct but still showing an error, you may need to verify that the invoice has been uploaded to the system prior to this submission. Correct any discrepancies and try uploading again.
