Getting a GSTIN is only the start. Over the life of a business, registration details change, businesses close or restructure, and the department can step in. GST recognises three distinct events on a registration — amendment, cancellation and suspension — and each has its own process and consequences. Here's how they work.

Quick answer
Your GST registration is not fixed forever — you can amend it, cancel it, and it can be suspended. Here's how each works and what triggers them.
When the details on your registration change, you are expected to update them rather than let them drift. Amendments cover things like a change of address, addition or removal of partners or directors, changes to the authorised signatory, or changes in the nature of your business. Some amendments take effect on your own application; others, particularly core changes, may require approval. The practical rule is to update promptly, because operating on stale registration details can itself create compliance problems.
You can apply to cancel your registration when you no longer need it — for example, if the business has closed, been transferred, or your turnover has genuinely fallen below the level at which registration is required and no compulsory trigger applies. Cancellation is not just stopping filing; it is a formal process with an application and, often, a final return to settle outstanding tax and reverse credit on stock held. Stopping filing without formally cancelling leaves the registration live and the obligations running.
The department can also cancel a registration on its own initiative, typically where there has been non-compliance — such as not filing returns for a continued period, or registration obtained by fraud or suppression. This is usually preceded by a notice giving you a chance to respond, so a cancellation rarely arrives without warning. Responding to that notice on time, and fixing the underlying default, is how you avoid losing the registration when the cause is curable.
Suspension is the in-between state. When cancellation is sought or initiated, the registration can be suspended in the meantime, which restricts what you can do — broadly, you are not meant to make taxable supplies or collect tax while suspended. Suspension is intended as a temporary status pending the outcome, not a penalty in itself, but operating normally during suspension creates exposure. Treat a suspension as a stop sign until the position is resolved.
Where the department has cancelled your registration, there is a route to apply for revocation if you act within the permitted window and clear the defaults that led to the cancellation. The sequence matters: file the pending returns, settle the dues, then apply. Throughout, remember that tax not paid on time attracts interest at 18% per annum, so the cheapest path is to keep your details current, file on time, and respond to notices promptly rather than letting a registration lapse.
Whenever the details on it change — address, partners or directors, authorised signatory, or the nature of your business. Some amendments take effect on your application while core changes may need approval, so update promptly rather than operating on stale details.
No — stopping filing leaves the registration live and the obligations running. Cancellation is a formal process, often involving a final return to settle outstanding tax and reverse credit on stock, and skipping it can lead to department-initiated cancellation.
Suspension is a temporary state, usually while cancellation is sought or initiated, during which you broadly cannot make taxable supplies or collect tax. It is not a penalty in itself, but operating normally while suspended creates exposure, so treat it as a stop sign until resolved.
