GST Cancellation & Revocation

A GST registration can be cancelled voluntarily, by applying in Form REG-16, or by the department, typically for failure to file returns over a continuous period. The two situations feel completely different but run through the same set of forms.

Voluntary cancellation is not simply stopping. All returns up to the date of cancellation must be filed, dues cleared, and a final return in Form GSTR-10 filed within three months of the cancellation order. Registrations abandoned without this continue to generate notices and late fees.

Departmental cancellation is more urgent. Once cancelled, you cannot issue tax invoices, your customers cannot claim input credit on what you supply, and e-way bills stop. Revocation must be applied for in Form REG-21 within thirty days of the order, extendable in stages up to ninety days.

Reply to the show-cause notice

Cancellation for non-filing is preceded by a show-cause notice in Form REG-17, with seven working days to reply. Filing the missing returns and responding at that stage prevents cancellation entirely. Once the order is passed, the position is far harder and more expensive to recover. The notice arrives on the portal, not by post, which is why it is so often missed.

The thirty days can be extended, but only in stages

The basic window for revocation is thirty days from service of the cancellation order. It can be extended by a further thirty days by the Additional or Joint Commissioner, and by another thirty by the Commissioner, on sufficient cause. Beyond ninety days there is no ordinary route back, and a fresh registration becomes the only option.

A cancelled GSTIN damages your customers

Once your registration is cancelled, invoices you issue are not valid tax invoices and your buyers cannot claim input credit. Business-to-business customers discover this in their GSTR-2B reconciliation and stop paying. This commercial consequence usually bites well before any tax consequence does.

Do not ignore GSTR-10

The final return is due within three months of the cancellation order and is separate from all your ordinary returns. Businesses that cancelled cleanly and moved on are regularly surprised by a late-fee notice for GSTR-10 a year later.

Credit reversal on stock

On cancellation you must pay an amount equal to the input tax credit on inputs held in stock and on capital goods, or the output tax on them, whichever is higher. Traders carrying inventory should compute this before choosing a cancellation date, because the date materially affects the amount.

All applications are made on the GST portal under sections 29 and 30 of the CGST Act, 2017.

Where the registration is cancelled, file GSTR-10 within three months and keep the acknowledgement. Retain records for the statutory period — cancellation does not end the department’s ability to examine past periods.

Where the registration is revoked and restored, bring all returns current immediately and set up a filing discipline. A second cancellation for the same reason is harder to reverse, and the department takes a dimmer view of it.

If you cancelled because turnover fell below the threshold, watch it. Crossing back over the limit requires fresh registration within thirty days, and supplying without registration once liable carries its own penalty.
