Cancellation of Registration under GST: Grounds, Procedure and ITC Reversal

Updated 5 October 2026 · Fact-checked

Cancellation of registration under section 29 of the CGST Act ends a person's GST registration, either on the registered person's application or by the proper officer on specified grounds after a show cause notice. To solve a question, identify the ground, follow notice and hearing, then compute the ITC payment on stock and capital goods and file the final return.

Understand Cancellation of Registration

A GST registration is not permanent. It can end when the business stops, changes form, or no longer needs registration. It can also be ended by the department when the person misbehaves, for example by not filing returns or by obtaining registration through fraud. This is cancellation of registration, governed by section 29 of the CGST Act and the related rules.

There are two routes. In the first, the registered person applies (or his legal heirs apply if he dies). In the second, the proper officer acts on his own motion. In both, the officer decides the date from which the cancellation takes effect. That date can be retrospective.

The grounds in section 29(1) cover the case where the business has been discontinued, transferred fully, amalgamated, demerged or otherwise disposed of. They also cover a change in the constitution of the business, and a person (other than a voluntary registrant) who is no longer liable to register. The grounds in section 29(2) are for officer-initiated cancellation. They are: contravention of prescribed provisions of the Act or rules; a composition person not filing returns for three consecutive tax periods; any other registered person not filing returns for a continuous period of six months; a voluntary registrant not starting business within six months of registration; and registration obtained by fraud, wilful misstatement or suppression of facts.

The officer cannot cancel without issuing a notice and giving the person an opportunity of being heard. Cancellation does not wipe out past liability. Tax, interest and penalty for the period up to cancellation stay payable, even if determined later.

Cancellation also has a cost. Under section 29(5) read with Rule 44, a registered person other than one paying tax under section 10 must pay an amount based on the ITC on inputs held in stock, inputs contained in semi-finished or finished goods, and capital goods or plant and machinery, on the day before cancellation. The amount is the higher of that ITC and the tax on the transaction value. A person who has been paying tax under section 10 is treated separately. He does not use the "higher of" computation. He pays only the ITC actually availed on stock and capital goods, as the rules provide for a composition person (read with section 18(4)). The person must also file a final return.

Revocation is a limited remedy. Under section 30, a registered person can seek revocation only where the proper officer cancelled the registration on his own motion. The application must be made within 30 days from the date of service of the cancellation order. The Additional or Joint Commissioner or the Commissioner may extend this by up to 30 days, and the Commissioner may extend it by a further period of up to 30 days. Revocation is not available where the registration was cancelled on the registered person's own application.

Key rules to remember

Grounds for cancellation on application or own motion (section 29(1)): Business discontinued / transferred / amalgamated / demerged / disposed of OR change in constitution OR ceasing to be liable (non-voluntary registrant); The proper officer may cancel from any date he thinks fit, including a retrospective date. The registered person or his legal heirs (on death) can apply.
Grounds for officer-initiated cancellation (section 29(2)): Contravention of prescribed provisions | Composition person: 3 consecutive tax periods of non-filing | Other person: 6 continuous months of non-filing | Voluntary registrant: no business within 6 months | Fraud, wilful misstatement, suppression; A notice and an opportunity of being heard are mandatory before cancellation.
Procedure steps (Rules 20 to 22): Application in FORM GST REG-16 | Show cause notice in FORM GST REG-17 | Reply in FORM GST REG-18 within 7 working days from service of the notice | Order in FORM GST REG-19 within 30 days of the reply | Or drop proceedings in FORM GST REG-20; Confirm the latest form numbers and time limits against the current rules text before the exam. Revocation under section 30 is available only where the proper officer cancelled the registration on his own motion, not where it was cancelled on the registered person's application. The application for revocation must be made within 30 days from the date of service of the cancellation order. The Additional or Joint Commissioner or the Commissioner may extend this by up to 30 days, and the Commissioner may extend it by a further period of up to 30 days.
ITC payable on cancellation (section 29(5) read with Rule 44): Amount payable = higher of (a) ITC on the stock or capital goods, and (b) tax on the transaction value of those goods; This computation applies to a registered person other than one paying tax under section 10. It covers inputs in stock, inputs in semi-finished and finished goods, and capital goods, as on the day immediately preceding the date of cancellation. A person who has paid tax under section 10 pays only the ITC actually availed on stock and capital goods (read with section 18(4)), not the "higher of" amount. Check the exact wording of the Act and Rule 44.
ITC on capital goods: ITC taken − 5 percentage points for every quarter or part of a quarter from the invoice date; Then compare with tax on the transaction value of the capital goods and pay the higher. Any part of a quarter counts as a full quarter.
Reporting and final return: Details of the reversal in FORM GST ITC-03 within 30 days of the cancellation date or order date, whichever is later | Final return in FORM GSTR-10 within 3 months of the cancellation date or order date, whichever is later; Read the question for the type of registrant. A regular person uses the higher-of computation. A composition person pays only the ITC actually availed on stock and capital goods.

How to solve Cancellation of Registration questions

Use this order for any question on cancellation of registration. It follows the provision, facts, conclusion format that examiners reward.

1Identify who initiates: the registered person (or legal heirs) or the proper officer. This decides the form of the application or notice.
2Match the facts to a ground. Check section 29(1) for business-related reasons and section 29(2) for default or misconduct. Note the type of registrant (regular, composition, voluntary).
3Check the time or count test. For non-filing, apply three consecutive tax periods for a composition person and six continuous months for others. For a voluntary registrant, apply six months from the registration date.
4Check the procedure. For officer action: notice, reply, hearing, reasoned order. State that cancellation without notice and hearing is not valid.
5State the effective date. The officer may fix any date including a retrospective date. Say so, and say that past liabilities continue.
6Compute the section 29(5) payment where stock or capital goods exist. For a person other than one paying tax under section 10, work out each category, apply the reduction for capital goods, compare with tax on transaction value and take the higher. For a composition person, state that he pays only the ITC actually availed on stock and capital goods, not the higher-of amount.
7List the follow-ups: ITC reversal reporting, payment of dues, and the final return. Mention revocation under section 30 only if the officer cancelled on his own motion and the question hints at a revival of business. Add that the application must be made within 30 days from service of the cancellation order, extendable as the law allows.
8Write a one-line conclusion that answers the exact question asked.

Quickest way: Three-check shortcut: Ground, Notice, Money

When to use it: Use when time is short, mainly in case-scenario MCQs and short descriptive questions.

Ground: put the fact into one of the section 29(1) or 29(2) boxes. If none fits, cancellation on that fact is not available.
Notice: if the officer acted, ask whether a notice and hearing were given. If not, the order is defective.
Money: if goods are in stock, compute ITC on stock and on capital goods (5 percentage points per quarter or part). Pay the higher of ITC or tax on transaction value for each category.
Finish with the final return and note that earlier liability remains.

Common mistakes in Cancellation of Registration

Saying the officer can cancel registration without a notice if the ground is clear, such as fraud.
Students think serious grounds remove the need for a hearing.
Fix: Write that a notice and an opportunity of being heard are required for every cancellation by the officer under section 29.
Mixing the non-filing limits, using six months for a composition person or three periods for a regular person.
Both limits look similar and are remembered as one rule.
Fix: Remember: composition person is three consecutive tax periods; any other registered person is six continuous months.
Believing cancellation ends all tax liability.
Students link cancellation with closure of the business.
Fix: State that liability to pay tax and discharge obligations for the period before cancellation continues, whether determined before or after cancellation.
Reversing only the ITC on capital goods at the full original amount, or forgetting the 5 percentage point reduction per quarter or part.
Students mix this with the ITC reversal rules on capital goods used for exempt supplies.
Fix: Reduce ITC by 5 percentage points for each quarter or part from the invoice date, then compare with tax on the transaction value and pay the higher.
Paying only the ITC on stock without comparing it with tax on the transaction value.
Students stop after the first number.
Fix: For a regular person, compute both figures for each category and take the higher of the two.
Applying the higher-of computation to a composition person, or saying a composition person pays nothing on cancellation.
Students remember the rule for regular persons and ignore the type of registrant.
Fix: Check the registrant type first. A person paying tax under section 10 pays only the ITC actually availed on stock and capital goods (read with section 18(4)), not the higher-of amount.
Ignoring the final return and the reporting of the reversal.
The numerical part gets all the attention.
Fix: End every answer with the FORM GST ITC-03 reporting and the final return, with the 30 days and 3 months timelines.
Saying revocation is available after every cancellation, or giving no time limit for it.
Students treat revocation as a general right to restore registration.
Fix: State that revocation under section 30 is available only where the proper officer cancelled on his own motion, not where cancellation was on the person's own application. The application must be made within 30 days from service of the cancellation order. The Additional or Joint Commissioner or the Commissioner may extend this by up to 30 days, and the Commissioner may extend it by a further period of up to 30 days.

Worked examples

Example 1

Mr. Rao, a registered regular trader, closes his business on 31 March 2027 and applies for cancellation. On 31 March 2027 he holds inputs with ITC of ₹40,000 (tax on their transaction value: ₹36,000) and finished goods with ITC of ₹30,000 (output tax on their transaction value: ₹45,000). He also holds a machine, bought 14 months earlier, on which he took ITC of ₹2,00,000. Tax on the machine's current transaction value is ₹1,26,000. Compute the amount payable under section 29(5) and state the other compliances.

Show the solution

Ground: the business has been discontinued, which is a ground under section 29(1). He applies, so the officer acts on the application.
Inputs in stock: ITC is ₹40,000. Tax on transaction value is ₹36,000. The higher is ₹40,000.
Finished goods: ITC is ₹30,000. Output tax is ₹45,000. The higher is ₹45,000.
Capital goods: 14 months is four full quarters plus a part of a quarter, so five quarters. The reduction is 5 × 5 = 25 percentage points. ITC after reduction = ₹2,00,000 × 75% = ₹1,50,000.
Compare with tax on transaction value, ₹1,26,000. The higher is ₹1,50,000.
Total payable = ₹40,000 + ₹45,000 + ₹1,50,000 = ₹2,35,000.
Compliance: report the reversal in FORM GST ITC-03 within 30 days of the cancellation date or order date, whichever is later, and file the final return in FORM GSTR-10 within 3 months of the same date. Mr. Rao is a regular person, so the section 29(5) payment applies to him in the usual way. Since cancellation was on his own application, revocation under section 30 is not available to him.

Answer: Mr. Rao must pay ₹2,35,000 under section 29(5), report it in FORM GST ITC-03 and file the final return. Liability for earlier periods continues.

Example 2

A composition dealer has not filed returns for three consecutive tax periods. The proper officer cancels the registration with retrospective effect, without issuing any notice. The dealer argues that (a) the cancellation is invalid and (b) he owes nothing for earlier periods because the registration is cancelled. Advise.

Show the solution

Provision: under section 29(2), the officer may cancel the registration of a person paying tax under section 10 who has not furnished returns for three consecutive tax periods. The cancellation may be from a retrospective date.
Facts: the ground is satisfied, since the dealer is a composition person and has defaulted for three consecutive tax periods.
Argument (a): the officer cannot cancel without a notice and an opportunity of being heard. So the order passed without notice is defective. The dealer is right on this point.
The correct procedure is a show cause notice in FORM GST REG-17. The dealer replies in FORM GST REG-18 within 7 working days from service of the notice. The officer then passes an order in FORM GST REG-19 within 30 days of the reply, or drops the proceedings in FORM GST REG-20.
Argument (b): cancellation does not affect the liability to pay tax and discharge obligations for the period before cancellation. The dealer is wrong on this point.
Further: if the cancellation is eventually confirmed, he must file the final return. Because the officer cancelled on his own motion, he can apply for revocation under section 30. The application must be made within 30 days from the date of service of the cancellation order. The Additional or Joint Commissioner or the Commissioner may extend this by up to 30 days, and the Commissioner may extend it by a further period of up to 30 days. As a composition person, he does not use the higher-of computation. He pays only the ITC actually availed on stock and capital goods, read with section 18(4).

Answer: The order is vulnerable because no notice and hearing were given, but the ground is valid. The dealer remains liable for dues up to the date of cancellation.

Exam tips

Learn the two lists in section 29(1) and 29(2) as a table of ground, who is covered and the time limit. Case scenarios usually test one of these limits.
In numerical questions, show the comparison of ITC and tax on transaction value for every category. Marks are given for each step, not only for the final total.
Count any part of a quarter as a full quarter for capital goods. Write the number of quarters explicitly.
In written answers, use the provision, facts, conclusion format and mention notice and hearing for officer-initiated cancellation.
Mention the follow-up compliances (FORM GST ITC-03, final return) in the closing line. Mention revocation only where the officer cancelled on his own motion.

Cancellation of Registration: frequently asked questions

Who can apply for cancellation of GST registration?

A registered person can apply, and so can his legal heirs if he dies. The application is made in FORM GST REG-16. The proper officer decides the date from which cancellation takes effect.

Can the department cancel my registration for not filing returns?

Yes. A composition person who has not filed returns for three consecutive tax periods, or any other registered person who has not filed for a continuous period of six months, can face cancellation. The officer must first give a notice and an opportunity of being heard.

What ITC do I have to pay back when my registration is cancelled?

Under section 29(5) read with Rule 44, a registered person other than one paying tax under section 10 pays on inputs in stock, inputs in semi-finished and finished goods, and capital goods, as on the day before cancellation. For each category, the payment is the higher of the ITC or the tax on the transaction value. For capital goods, the ITC is first reduced by 5 percentage points per quarter or part from the invoice date. A composition person pays only the ITC actually availed on stock and capital goods.

Does cancellation remove my past tax liability?

No. Liability to pay tax and other dues for the period before cancellation continues. It applies whether the dues are determined before or after cancellation.

Can a cancelled registration be restored?

Only in some cases. Under section 30, revocation is available to a registered person whose registration was cancelled by the proper officer on his own motion. The application must be made within 30 days from the date of service of the cancellation order. The Additional or Joint Commissioner or the Commissioner may extend this by up to 30 days, and the Commissioner may extend it by a further period of up to 30 days. It is not available where the registration was cancelled on the person's own application. Study that topic together with this one.
