Revocation of cancellation of registration clarified under GST rules, with return-filing and payment conditions for cancellation cases. Clarification is issued on the procedure for applications seeking revocation of cancellation of registration under the Uttarakhand GST law. The circular covers registrations cancelled for non-filing of GSTR-3B or GSTR-4 returns, the additional opportunity granted to specified persons to apply for revocation by 22.07.2019, and the conditions under Rule 23 requiring filing of all pending returns and payment of dues before revocation. It also explains the position where cancellation operates retrospectively and returns must be filed within thirty days of the revocation order.
