Can GST registration be cancelled for excess turnover in GSTR-1 for any period within 2020-21?

This discussion clarifies whether a GST registration can be cancelled if the turnover reported in GSTR-1 exceeds that in GSTR-3B for any period before December 2020. While a mismatch doesn't automatically lead to cancellation under Rule 21(f) of the CGST Rules, GST officers do have the power to cancel registration in such scenarios. However, they may opt to suspend the registration instead of cancelling it outright.
