As per the GST portal data policy, data for view by the taxpayer is to be retained for 7 years only. Hence return data will not be available for view beyond 7 years on GST Portal.
The data archival is going to be a monthly activity. Consequently, the data for July 2017 and August 2017was archived on 1ST August and 1ST September respectively.
However, in view of request from the trade due to the difficulties faced, data has been restored back to the portal.
Hence data for the periods July, August and September 2017 may be downloaded and saved as the archival policy may be implemented again.
