I am getting an error “You have not filed last tax period’s return as a normal taxpayer” when I click on “PROCEED TO FILE” button. Why?

On clicking “PROCEED TO FILE” button, GST Portal will check if the last applicable return in Form GSTR-3B which has become due is filed or not. If the return in Form GSTR-3B has not yet been filed, you will get error message that “You have not filed last tax period’s return as a normal taxpayer. Please file the same before attempting to file statement in Form GST CMP-08.”

For Example: Taxpayer opts for composition scheme w.e.f. 1st April 2021 and the first quarterly statement in Form GST CMP-08 becomes due for the quarter ending June 2021 on 18th July 2021. The taxpayer was a normal taxpayer till 31st March 2021 of the previous financial year and the return for the month/quarter ending March, 2020-21 in Form GSTR-3B had become due in April of the current financial year. In such cases, whenever the taxpayer attempts to file Form GST CMP-08 for the Apr-Jun quarter of 2021-22 tax period, GST Portal will check if Form GSTR-3B of period ending Mar’21 has been filed by the taxpayer or not and display an error message if it is yet to be filed.
