Choose the correct portal route for voluntary cancellation, officer cancellation, revocation or appeal and calculate indicative deadlines.
Identify the correct GST route
Calculation basis
Ordinary revocation is due within 90 days from service. A separately authorised written extension may grant up to 180 further days; it is not automatic. Appeal limitation is a different calculation.
Source check: 21 October 2026. Current CGST Rule23(1) and extension proviso.

How This Is Calculated
This tool maps a GST cancellation situation (voluntary cancellation, department-initiated cancellation, or a cancellation order you want reversed) to the correct next action and its deadline — revocation of a department-cancelled registration and appeal against a cancellation order both run on strict, date-bound windows from the order date.
Frequently Asked Questions
What is the difference between revocation and appeal against GST cancellation?
▼
Revocation is a request to reverse the cancellation, generally filed within a set window from the cancellation order, often used when the taxpayer can now demonstrate compliance (like filing pending returns). An appeal instead challenges the cancellation order itself as incorrect, filed with the appellate authority within its own separate deadline.
What happens if I miss the revocation deadline?
▼
Once the revocation window from the cancellation order lapses, the appeal route (with its own separate, generally longer deadline structure including possible condonation of delay) may be the only remaining option — acting quickly within the initial revocation window is usually the simpler path.
Source and review trail
Use the current official instrument, portal or regulator publication before acting.
Scope: Guides a taxpayer through GST registration cancellation, revocation of cancellation, and the appeal process for a rejected revocation, based on the grounds and timelines under Section 29-30 of the CGST Act.
Calculation logic
Cancellation (voluntary or by the proper officer): identify the applicable ground (e.g., discontinuance of business, non-filing of returns for the prescribed continuous period, voluntary registration not commenced business within the prescribed period) and the corresponding form (REG-16 for voluntary application).
Revocation of cancellation (where cancelled by the officer): must generally be applied for within the prescribed period (90 days from service of the cancellation order, with a separately authorised further extension of up to 180 days) via Form REG-21, after filing all pending returns and paying due tax/interest/late fee.
Appeal (where a revocation application is rejected): outline the appeal route to the Appellate Authority under Section 107, within the prescribed limitation period from the date of the rejection order.
Inputs and assumptions
Timelines and procedural steps follow the current CGST Act/Rules provisions for cancellation, revocation and appeal, including any extended timelines notified for pending compliance/amnesty windows where applicable at the time.
Revocation is available only where the registration was cancelled by the proper officer (not where cancelled voluntarily by the taxpayer) — the tool routes the user to the correct process based on how the cancellation occurred.
Exclusions and edge cases
This is a guidance/checklist tool, not a filing mechanism — actual applications (REG-16, REG-21, appeals) must be filed through the GST portal or the appropriate appellate forum.
Complex disputed-cancellation scenarios (e.g., cancellation alleged for fraud/wilful misstatement) carry additional procedural and evidentiary requirements beyond this general guidance.
