4. Mismatch of filed data in monthly and quarterly returns
Taxpayers should ensure that all monthly and quarterly filed returns match with the data reported in the GSTR-9. Mismatch of data could be one of the primary causes of getting a demand notice at a later date from the GST department. While the due date for making amendments to data of FY 17-18 has passed, taxpayers can still disclose any additional tax liability in the GSTR-9 return.The same can be paid in form DRC-03.
5. Not maintaining proper documentation
Before filing the annual return, it is the duty of the taxpayer to reconcile, verify and report only accurate information. In addition to this, the taxpayer should ensure that there is substantial documentary proof of all data that is reported in the return, in order to avoid unnecessary hassles at a later date.
