Error in inverted tax refund stmt 01A submission

It sounds frustrating to encounter that error repeatedly. The “period not matching” error typically occurs when the period entered in Statement 01A does not align with the period selected in the refund application on the GST portal. Here are a few steps you can follow to resolve this issue:

Check the Period Format: Ensure that the period format in Statement 01A matches the format required by the GST portal (usually in MMYYYY format).
Consistency in Periods: Verify that the period mentioned in the refund application matches exactly with the period mentioned in Statement 01A. Both should cover the same time frame.
Update and Re-upload: If there are any discrepancies, correct the period in Statement 01A and re-upload it. Make sure to save the changes before uploading.
Offline Utility: Use the offline utility provided by the GST portal to prepare and validate Statement 01A. This can help in identifying and correcting errors before uploading.
Clear Cache and Cookies: Sometimes, clearing the browser cache and cookies can resolve unexpected errors on the GST portal.
