GST Registration Cancellation in 2026: Voluntary, Suo Moto, Revocation and the Final Return

Closing a business, merging it into a company, or dropping below the GST threshold doesn't end your GST obligations by itself — the GSTIN stays live, and so do the returns and late fees, until the registration is formally cancelled. And if you've stopped filing, the department may cancel it for you. This guide is for proprietors, partners and accountants dealing with either side of that: how to apply for cancellation in REG-16, what suo moto cancellation and suspension mean, how to get a cancelled registration back with REG-21, how to file the GSTR-10 final return, and how much tax you pay on stock in hand, with a ₹ example. Everything was checked against the CGST Act, CGST Rules and GST portal FAQs in October 2026.

Quick answer

To cancel GST yourself, file REG-16 on gst.gov.in within 30 days of the event (closure, transfer, turnover below the limit). The GSTIN is suspended at once; the officer issues the cancellation order in REG-19 within 30 days. You then file the final return GSTR-10 within three months from the date of cancellation or the cancellation order, whichever is later, paying back ITC on stock in hand.

• Officer-initiated (suo moto) cancellation starts with a REG-17 notice — reply in REG-18 within 7 working days

• Revocation of a suo moto cancellation: REG-21 within 90 days, extendable by up to 180 more days

• GSTR-10 late fee: ₹200 a day (₹100 CGST + ₹100 SGST), up to ₹10,000 (₹5,000 CGST + ₹5,000 SGST)

• Cancellation never wipes out tax, interest or penalties for earlier periods

When can GST registration be cancelled?

Section 29 of the CGST Act allows cancellation in two ways: on your own application (or your legal heir's, if a proprietor dies), or by the officer on their own motion — "suo moto". The grounds are different, and so are the forms.

Voluntary grounds. You can apply if the business has been discontinued, transferred fully (including on the death of the proprietor), amalgamated with another entity, demerged or otherwise disposed of; if the constitution of the business changes in a way that changes the PAN — say, a proprietorship becoming a private limited company; or if you're no longer liable to be registered, for example because turnover has fallen below the ₹40 lakh (goods) or ₹20 lakh (services) threshold. A person who registered voluntarily can also opt out at any time; the old rule that blocked this for the first year was dropped in 2018.

Officer's grounds. Under section 29(2) and Rule 21, the officer can cancel if you:

• haven't filed returns for six continuous months as a monthly filer, or for two continuous tax periods as a QRMP filer;
• are a composition taxpayer who hasn't filed the annual return for three months beyond the due date of the annual return;
• registered voluntarily but didn't start business within six months;
• don't conduct business from the declared place of business;
• issue invoices without supplying goods or services, or claim ITC in breach of section 16;
• report more outward supplies in GSTR-1 than in GSTR-3B for one or more periods;
• breach Rule 10A (no valid bank account details) or Rule 86B (the 1% cash payment rule);
• obtained registration by fraud, wilful misstatement or suppression of facts.

The officer can cancel from any date, including a retrospective one. That matters because a backdated cancellation can make the credit your buyers claimed on your invoices after that date open to question.

How to cancel GST registration voluntarily (REG-16)

Rule 20 requires the application within 30 days of the event that warrants cancellation. The portal enforces it: in REG-16 you can't choose a "date from which cancellation is sought" more than 30 days before the application date. Persons registered only as TDS deductors or TCS collectors, and UIN holders, can't use REG-16, and you can't file it once the officer has already started suo moto proceedings — you have to reply to their notice instead.

Filing REG-16 on the GST portal

1. 1

   File all pending returns first

   Bring GSTR-1 and GSTR-3B up to date to the date of cancellation. Pending returns block GSTR-10 later, and late fee keeps accruing on them.

2. 2

   Open the cancellation form

   Log in at gst.gov.in → Services → Registration → Application for Cancellation of Registration. The form has three tabs: Basic Details, Cancellation Details and Verification.

   Open the GST portal
3. 3

   Give the reason and date

   Pick the reason (discontinuance, transfer, amalgamation, change in constitution, below threshold, death of proprietor and so on) and the date from which you want cancellation. For a merger or transfer, enter the transferee's GSTIN — it must already be registered.

4. 4

   Declare stock and capital goods

   Enter the value of inputs, semi-finished and finished goods, and capital goods held on the day before the cancellation date, with the tax on them. You can pay it now or with GSTR-10; a nil entry is allowed if you hold no stock.

   Tip: Amounts paid with REG-16 are adjusted automatically against the GSTR-10 liability.

5. 5

   Verify and submit

   Sign with DSC (mandatory for companies and LLPs) or EVC. An ARN is generated and the GSTIN shows as 'Suspended'.

6. 6

   Respond to queries and get REG-19

   If the officer asks for clarification, reply on the portal. The cancellation order in REG-19 should come within 30 days. Then file GSTR-10.

Once you've filed REG-16, you can't change core fields such as legal name or address, though non-core fields, email and mobile can still be updated. If the officer rejects the application, the GSTIN goes back to "Active" and normal filing resumes.

Suspension: what happens while cancellation is pending

Rule 21A treats a registration as suspended whenever cancellation proceedings are pending. On a REG-16, suspension starts from the date of the application or the date from which cancellation is sought, whichever is later. On suo moto proceedings, the officer can suspend from a date they choose, usually the date of the REG-17 notice.

Since 2020, suspension can also be automatic. Under Rule 21A(2A), if comparing your GSTR-3B with your GSTR-1, or with your suppliers' GSTR-1, shows significant differences or anomalies — or if you haven't furnished valid bank account details under Rule 10A — the system suspends the GSTIN and sends an intimation in REG-31. You have 30 days to explain. Where the suspension was for non-filing, it lifts automatically when you file all pending returns; for the bank-account case, it lifts when you add the account.

During suspension you must not issue tax invoices or charge GST, so you can't make taxable supplies; you don't file GSTR-1 or GSTR-3B for the suspended period; and refunds are withheld if the suspension came from the officer or REG-31. You can still pay dues, file returns for earlier periods, reply to notices, file appeals and claim refunds of earlier periods where allowed. If the suspension is later revoked, it's treated as never having applied, and you can issue invoices for supplies made in the interim under the revised-invoice route in section 31(3)(a).

final return or revocation

When an officer believes your registration should be cancelled, Rule 22 requires a show-cause notice in REG-17 first. It appears under Services → User Services → View Notices and Orders, and an email goes to your registered address.

You have 7 working days from service of the notice to reply in REG-18 (Services → Registration → Application for Filing Clarifications). Explain the facts and attach evidence — rent agreement and photographs for a "not functioning at the declared address" notice, for example. If the notice is for non-filing, the quickest answer is to file every pending return and pay the tax, interest and late fee: the rules then require the officer to drop the proceedings in REG-20 even without a detailed reply.

If the reply isn't satisfactory or you don't reply, the officer cancels in REG-19 within 30 days of the reply date, from a date they determine, and directs you to pay any arrears of tax, interest and penalty including the section 29(5) amount on stock. Section 29 requires that you be given an opportunity of being heard before cancellation; an order passed without one, or without reasons, can be challenged.

Revocation of cancellation: REG-21 time limits

Revocation after a suo moto cancellation

Day 0

REG-19 cancellation order served

Within 90 days

File REG-21 — after filing pending returns and paying tax, interest and late fee if cancelled for non-filing

Up to 180 more days

Extension by a Joint/Additional Commissioner or higher on sufficient cause

Within 30 days of REG-21

Officer revokes (REG-22) or issues REG-23 notice; reply in REG-24 within 7 working days

Within 30 days of revocation

File all returns for the period from cancellation (or its retrospective effective date) to revocation

Revocation is available only where the officer cancelled on their own motion. If you cancelled voluntarily and want to restart, apply for a new registration instead — see our GST registration guide.

The time limit has changed twice, which is why older articles disagree. The Act originally allowed 30 days. From 1 August 2023 (Notification 38/2023-CT), Rule 23 allows 90 days from the date the cancellation order was served, and the Commissioner or an officer authorised by them, not below Joint or Additional Commissioner, can extend this by a further up to 180 more days on sufficient cause recorded in writing. From 1 October 2023 the Act itself leaves the time limit to the rules.

Two conditions catch people out. If the registration was cancelled for not filing returns, you can't file REG-21 until those returns are filed and the tax, interest, penalty and late fee are paid. And once revocation is granted, you must file all returns for the gap — from the cancellation order (or its retrospective effective date) to the revocation order — within 30 days.

The officer decides within 30 days: revocation in REG-22, or a notice in REG-23 asking why the application shouldn't be rejected, which you answer in REG-24 within seven working days. A rejection comes in REG-05, and you can appeal it to the Appellate Authority under section 107. If the 90 days and the extension have passed, an appeal against the original cancellation order is usually the remaining route. Our GST late fee guide shows what the pending returns will cost.

Stock ITC reversal: what you pay on cancellation

You claimed credit on purchases on the basis that you would sell the goods with GST. If the registration ends while goods are still in stock, section 29(5) takes that credit back. You pay, from the credit ledger or cash ledger, the higher of:

• the ITC on inputs held in stock and inputs contained in semi-finished and finished goods held on the day before cancellation; or
• the output tax payable on those goods (at their value on that day).

For capital goods and plant and machinery, you pay the higher of the ITC taken reduced for the period of use, or the tax on their transaction value. Rule 44 sets the method: credit on stock is worked out proportionately from the purchase invoices, and credit on capital goods is spread over a useful life of five years (60 months), so you repay only the share for the remaining whole months. Where invoices aren't available, you estimate on the prevailing market price. Each tax head — CGST, SGST, IGST — is worked out separately. For the underlying credit rules, see our input tax credit guide.

Worked example: closing a garment shop in Ludhiana

Kaur Garments, a proprietorship in Ludhiana, closes on 31 August 2026 and applies in REG-16 on 10 September with cancellation from 1 September. On 31 August it holds:

The capital-goods line uses Rule 44: from 1 April 2024 to 31 August 2026 is 2 years, 5 months — 29 months used, so 31 whole months of the 60-month life remain. ITC attributable = ₹36,000 × 31 ÷ 60 = ₹18,600. That's higher than 18% tax on the ₹90,000 resale value (₹16,200), so ₹18,600 is payable.

Kaur Garments has ₹12,000 left in its credit ledger, which it uses first; the remaining ₹34,100 is paid in cash. Since the shop is in Punjab and all stock was bought within the state, the amounts split equally between CGST and SGST. It reports the figures in REG-16 and again in Table 8 of GSTR-10. If it sells the stock to another registered dealer before the cancellation date — with a proper tax invoice — the stock leaves the books and no reversal is needed on it.

GSTR-10: the final return

Every normal taxpayer whose registration is cancelled must file GSTR-10 within three months from the date of cancellation or the cancellation order, whichever is later, under section 45. Composition taxpayers, Input Service Distributors, non-resident taxable persons, TDS deductors, TCS collectors and OIDAR suppliers are excluded. Despite the name, GSTR-10 isn't a summary of the business's whole life; it's a statement of stock held on the day before cancellation and the tax on it.

You'll find it at Services → Returns → Final Return once the REG-19 order is issued. All GSTR-1 and GSTR-3B returns up to the effective date must already be filed, the full liability must be paid before you can submit, and a filed GSTR-10 can't be revised. Nil GSTR-10 is allowed if you held no stock. Your login stays active for these post-cancellation tasks.

Late filing costs ₹200 a day (₹100 CGST + ₹100 SGST), up to ₹10,000 (₹5,000 CGST + ₹5,000 SGST) — the 2023 amnesty that capped this lower has ended. If you don't file at all, the portal issues a GSTR-3A default notice giving 15 days; after that the officer can assess the liability under section 62 using available information, which usually means a higher figure than your own.

Common mistakes and what to do after cancellation

Closing your GST registration

0/6

• All GSTR-1 and GSTR-3B filed up to the closing date
• Stock sold, transferred or valued for the section 29(5) payment
• REG-16 filed within 30 days of closure
• REG-19 order downloaded
• GSTR-10 filed within three months of the order
• Records kept for six years

Share Print

Waiting too long to apply. Every month the GSTIN stays active, GSTR-1 and GSTR-3B fall due. A closed shop that doesn't file nil returns runs up late fees on each one and eventually faces suo moto cancellation — with retrospective effect and a demand.

Assuming cancellation clears old dues. Section 29(3) is explicit: tax, interest and penalties for periods before cancellation remain payable, whether determined before or after the cancellation. Notices for old years can still arrive.

Forgetting e-way bills and e-invoices. You can't generate either once the GSTIN is suspended, so dispatch remaining stock before you apply, or transfer it to the buyer of the business.

Ignoring buyers' credit. If the officer cancels retrospectively, invoices you issued after the effective date may be questioned in your buyers' hands. Replying promptly to REG-17 protects customer relationships as much as your own position.

Keep records. Books and documents must be kept for 72 months from the due date of the annual return for the year concerned, even after cancellation. Store the REG-16 or REG-19, GSTR-10 acknowledgement and challans together.

What to do next

If you're closing down, file every pending return, sell or transfer what stock you can, and apply in REG-16 within 30 days. If you've received a REG-17 or REG-31, reply within the deadline — filing the pending returns is often enough. Check your GSTIN's status any time with our GSTIN guide, and use the GST late fee guide to cost any overdue returns before you file.

Frequently asked questions

How do I cancel my GST registration?

Log in at gst.gov.in and go to Services → Registration → Application for Cancellation of Registration (Form REG-16). Give the reason, the date from which you want cancellation, and the value of stock and capital goods with the tax on them. Apply within 30 days of the event, such as closing the business. The officer issues the order in REG-19, then you file GSTR-10.

What is suo moto cancellation in GST?

Suo moto cancellation is when the tax officer cancels your registration on their own — for example for not filing returns for six continuous months (monthly filers), not running a business from the declared address, or obtaining registration by fraud. The officer first issues a show-cause notice in REG-17; you reply in REG-18 within 7 working days. The officer then drops it (REG-20) or cancels (REG-19).

What is the time limit for revocation of GST cancellation?

You can apply for revocation in Form REG-21 within 90 days of the date the cancellation order was served. On sufficient cause, a Joint or Additional Commissioner (or higher) can extend it by up to 180 more days. If cancellation was for non-filing, you must first file all pending returns and pay the tax, interest and late fee.

Is GSTR-10 mandatory after cancellation?

Yes, for normal taxpayers. GSTR-10, the final return, must be filed within three months from the date of cancellation or the cancellation order, whichever is later. It reports stock held on the day before cancellation and the tax on it. Composition taxpayers, ISDs, non-residents, TDS/TCS registrants and OIDAR suppliers don't file it. Late filing costs ₹200 a day (₹100 CGST + ₹100 SGST), up to ₹10,000 (₹5,000 CGST + ₹5,000 SGST).

Do I have to pay tax on stock when cancelling GST?

Yes. Under section 29(5) you pay back the input tax credit on inputs, semi-finished and finished goods in stock on the day before cancellation, or the output tax on those goods if that's higher. For capital goods, you pay the credit for their remaining life (on a five-year basis) or tax on their transaction value, whichever is higher.

What happens to my GSTIN when I apply for cancellation?

It becomes 'Suspended' from the date of the application or the date from which you want cancellation, whichever is later. During suspension you can't issue tax invoices or charge GST, and you don't file GSTR-1 or GSTR-3B for that period. You can still make payments, file old returns, reply to notices and file appeals.
