You want out. The turnover dropped after a client left, or you have closed the practice and taken a job, or — the most common one among independent professionals — you registered because a client asked for a GSTIN and you have spent two years filing nil returns for a threshold you never actually crossed.
A registration is not free to hold. Every month it exists it owes returns whether or not you billed anything, and the cost of holding one you do not need is paid quietly, in late fees and in attention. Getting out is not a decision you can simply make, though: it is an application, and it has a clock on it that most people discover late.
The event, and its date
Cancellation follows an event; it is not a preference. “I do not want to file returns any more” is not a ground, and an application that amounts to that is an application inviting a question. So the first work is not the form — it is pinning down what happened and when.
Which of these describes you, and on what date did it become true?
- The business stopped. You closed the practice, took employment, or otherwise stopped making taxable supplies. The date is the last supply, not the day you updated your profile.
- The constitution changed. The entity that holds the registration is not the entity carrying on the business any more — a proprietorship folded into something else, a transfer, a succession.
- You are no longer liable to be registered. Turnover fell away, or the reason you were required to register no longer applies. If you are unsure whether you were ever over the line, settle the threshold question first — it decides whether this is a cancellation or a mistake worth understanding before you repeat it.
The application itself asks you to pick the reason and state the date. Both answers travel with the file, and the date is what the officer’s order will be written against, so treat it as the most load-bearing thing you will type.
The application: REG-16
You apply on REG-16 — the Application for cancellation of registration — under CGST Act s.29(1) read with CGST Rule 20, and the window is within thirty days of the event warranting cancellation — the date you stopped being liable to be registered, not the date you decided to deregister.
It is filed on the GST portal against your existing registration. That is a destination rather than a click-path, and deliberately so: portal menus move, and a page that walks you confidently through navigation that has since changed is worse than one that tells you where you are going. Correct as of August 2026.
A cancellation you applied for and never checked is a registration you still have.
What happens after you apply
Three things can come back, and knowing which is which is the whole of “checking your status”.
- REG-19 — the Order for cancellation of registration, to be issued within thirty days of the application, under CGST Rule 22. This is the document that actually ends the registration, and it states the date from which it does so.
- REG-20 — what issues instead where the cancellation proceedings are dropped. You are still registered. Every obligation continues, and reading this as “nothing happened” is how people spend a year not filing.
- REG-03 — the Notice for seeking additional information / clarification / documents relating to an application for registration, amendment or cancellation. Note that its own title covers applications for cancellation, not just for registration: the officer can come back with a question about yours. The answer goes on REG-04 and the window is within seven working days from the date of receipt of the notice — note the working, and note that it runs from receipt rather than from the day you next log in. A clarification that lapses unanswered leaves the officer holding a question and no answer to it.
So the status that matters is not “submitted”. Track the application against its ARN on the portal, as of August 2026, and keep looking until one of those three has actually issued.
Before you decideMost cancellations by independent professionals are a correction of an earlier guess. HourSlip tracks turnover against the registration threshold as invoices are raised, so both decisions — coming out now, and whether you have to go back in later — are made from a number rather than a feeling.After the order
From the effective date in REG-19, you no longer hold the registration — which means you must not charge GST on anything you invoice, and must not print the old GSTIN on a document. Bill your fee, and be paid for it. Clients whose systems ask for a GSTIN will ask; the answer is that you are not registered, which is a fact about you and not a defect in your invoice.
Nothing here touches income tax. Advance tax, your presumptive position and your return are unchanged by leaving GST — those obligations run on their own calendar and a cancelled registration does not quiet any of them. And if your practice picks back up and you cross the threshold again, registering again is a fresh application, so keep the record that would support one.
If the department cancelled you instead
Worth stating plainly because the two get searched with the same words and the routes are opposite. If you did not apply — if the registration was cancelled on the officer’s own motion — you are not cancelling, you are trying to undo a cancellation, and the form above is the wrong one.
That remedy is REG-21, the Application for revocation of cancellation of registration, under CGST Act s.30 read with CGST Rule 23. It must be filed within 90 days of the date of the cancellation order. Beyond that it can be made between 91 and 270 days of the cancellation order, and only if the Commissioner (or an officer not below Additional/Joint Commissioner) accepts the reason for the delay — a request that can be refused, rather than a right. And there is a precondition that traps most people: no revocation application can be filed where the registration was cancelled for failure to furnish returns, unless those returns are furnished and the tax due is paid along with any interest. In other words, the filing has to be caught up before the application can be made at all, which is why that first window disappears so fast.
What to do this week
- Fix the event and its date. Everything else is written against that date.
- Check what is outstanding against your GSTIN and clear it before, not after, you apply.
- File REG-16, stating the reason and the date honestly.
- Watch for a REG-03 and diarise within seven working days from the date of receipt of the notice.
- Keep filing until the effective date in REG-19 says you may stop — and check the portal until that order exists.
If step 2 takes you more than an afternoon, that is the real finding here, and it is the same thing that made a registration you did not need expensive to hold.
