Suo motu cancellation and the revocation route
A registration cancelled for non filing can usually be restored. The window is short and the arithmetic is unforgiving.
Where a registration is cancelled by the proper officer under Section 29(2), an application for revocation may be made in REG-21 within thirty days of the service of the cancellation order, extendable by the Additional or Joint Commissioner and further by the Commissioner in the manner prescribed. Where the cancellation was for non filing of returns, revocation requires the returns to be filed and the tax, interest and late fee paid. Beyond the extended periods the remedy is an appeal under Section 107 or a writ.
The sequence and the dates
A notice in REG-17 proposes cancellation. A reply in REG-18 is due within the period stated. Cancellation is ordered in REG-19.
An application for revocation in REG-21 must be filed within thirty days of service of the cancellation order. The rules permit extension by the Additional or Joint Commissioner and a further extension by the Commissioner, on sufficient cause.
Where cancellation was for non filing, all returns due up to the date of cancellation must be filed and the dues paid before the application.
The officer may issue a notice in REG-23 seeking clarification, to be answered in REG-24, and revocation is ordered in REG-22 or rejected.
The practical difficulty, and how to solve it
The returns cannot be filed while the registration is cancelled on the portal in some situations, which creates the circularity that produces most of this litigation. Where that occurs, the point must be recorded in the application and a writ sought.
The late fee for years of unfiled returns can exceed the tax. Check whether an amnesty for late fee applies to the periods concerned, because it has been notified more than once.
The commercial urgency is usually a customer requirement or a tender, so speed matters more than the argument. File the application with everything, rather than in stages.
Where the thirty day period and the extensions have passed, the appeal under Section 107 is available, and High Courts have repeatedly permitted revocation on terms where the taxpayer files returns and pays dues.
Consequences while cancelled
Supplies made during the cancelled period are supplies by an unregistered person, and the customer's credit is at risk, which is usually how the taxpayer discovers the problem.
The final return in GSTR-10 becomes due within three months of cancellation, and its non filing carries its own late fee and a further notice cycle.
Credit in the electronic credit ledger is dealt with under Section 29(5), and the reversal on cancellation must be computed.
Assessment under Section 63 for the period after cancellation, where liability continued, is a real exposure and it is why dormant registrations should be cancelled properly rather than abandoned.
What to do on Monday
Diarise the thirty day revocation window from the date of service, and file with everything at once.
Check for a late fee amnesty applicable to the periods before paying.
Record any portal impossibility in the application itself, to support later relief.
Communicate with affected customers promptly; their credit is the commercial consequence.

Write to the GST practiceQuestions we are asked on this
How long do we have to apply for revocation?
Thirty days from service of the cancellation order, with extensions available from the Additional or Joint Commissioner and the Commissioner on sufficient cause.
Can we file returns after cancellation?
Where the portal does not permit it, record the difficulty in the application and seek a direction. That circularity is a common ground for relief.
Is the late fee waived?
Amnesty schemes for late fee have been notified for specified periods. Check whether one applies before paying.
What happens to supplies made while cancelled?
They are supplies by an unregistered person, and the recipient's credit is at risk. Regularise quickly and communicate with customers.
Is an appeal available after the extended period?
Yes, under Section 107, and courts have frequently permitted revocation on terms even later.
