if the registration has been cancelled for failure to furnish returns, application for revocation shall be filed, only after such returns are furnished and any amount due as tax, in terms of such returns, has been paid along with any amount payable towards interest, penalty and late fee in respect of the said returns. 

As per Rule 23 of CGST Rules, 2017 Revocation of cancellation of registration is as follows:

1) A registered person, whose registration is cancelled by the proper officer on his own motion, may submit an application for revocation of cancellation of registration, in FORM GST REG-21, to such proper officer, within thirty days from the date of service of the order of cancellation of registration at the Common Portal, either directly or through a Facilitation Centre notified by the Commissioner.

2) Where the proper officer is satisfied, for reasons to be recorded in writing, that there are sufficient grounds for revocation of cancellation of registration, he shall revoke the cancellation of registration by an order in FORM GST REG-22 within a period of thirty days from the date of the receipt of the application and communicate the same to the applicant.
