GST registration cancellation for return default remains reversible only through complete, time-bound filing and payment compliance.
GST registration may be cancelled for continuous non-filing of returns, but cancellation does not discharge pre-cancellation tax liabilities. Before cancellation, Rule 22(4) requires proceedings to be dropped where the taxpayer files all pending returns and pays tax, interest and late fee. Post-cancellation revocation under Rule 23 is a separate mechanism requiring complete filing and payment compliance within the applicable time limits. Conditional restoration may be appropriate where liabilities are fully regularised, while absence of fraud does not excuse default or replace statutory compliance.
