How to cancel your GST registration

If you stop the business, fall below the threshold, or no longer need the registration, you can apply to cancel it on the GST portal.

The process

File the cancellation application with the reason and effective date. The officer may ask for clarification before approving.

Final return

After cancellation you must file a final return (GSTR-10) within the prescribed time, and reverse credit on any stock you still hold. Until you cancel formally, you are expected to keep filing returns, so do not just stop.
