GST registration was cancelled? You have 90 days to apply for revocation using Form REG-21. Missing this window means reapplying as a new taxpayer. Here is the complete process.
When your GST registration is cancelled — whether by your own application or by the department — it does not necessarily have to be permanent. The GST Act provides a revocation mechanism through Form REG-21, allowing taxpayers to restore their cancelled registration without going through the full re-registration process.
However, revocation is only available in specific circumstances, and the time limit is strict: 90 days from the date of the cancellation order. If you miss this window, you lose the right to revoke and must apply for a fresh GST registration as a new taxpayer — which means a new GSTIN, new returns filing history, and loss of any accumulated ITC balance.
This guide covers everything: when revocation applies, when it does not, exactly how to file REG-21 on the GST portal step by step, what documents you need, and what happens after you file. We also explain the extended timeline for cases involving High Court stays and GST Tribunal directions.
Once your registration is restored, use myBillPlease to get back to compliant invoicing and filing immediately.
Only registrations cancelled by the department (suo motu) can be revoked. Voluntary cancellations follow a different path.
| Feature | Cancellation Type | Can Be Revoked? | Form Used | Time Limit |
|---|---|---|---|---|
| Department cancelled — non-filing of returns | Yes | REG-21 | 90 days from cancellation order | |
| Department cancelled — business not found at address | Yes | REG-21 | 90 days from cancellation order | |
| Department cancelled — non-commencement of business | Yes | REG-21 | 90 days from cancellation order | |
| Department cancelled — registration obtained by fraud | No — only appeal available | N/A | Appeal within 3 months of order | |
| Voluntary cancellation by taxpayer | No revocation — apply for new registration | REG-01 | New application anytime | |
| Cancellation due to death of proprietor | No — transfer to legal heir | REG-16 | N/A |
Before filing your revocation application, you must meet specific conditions. Filing without meeting these will result in rejection and waste critical days from your 90-day window.
1. All pending returns must be filed. This is the most important prerequisite. If your registration was cancelled for non-filing, you must file all pending GSTR-1 and GSTR-3B returns up to the date of cancellation before the portal will accept your REG-21. There is no shortcut here. File all outstanding returns first, pay all late fees, and then apply for revocation.
2. All outstanding tax, interest, and penalty must be paid. Log into your GST portal and check the outstanding liabilities under the Electronic Liability Register (ELL). Clear every rupee before applying. The system will not allow the revocation application if there are pending dues.
3. The cancellation must be by a proper officer's order, not a system-generated cancellation due to migration issues. Migration-era issues may need to be resolved through a grievance on the portal before revocation is possible.
4. You must still be liable for GST registration. If your turnover dropped below the threshold (₹40 lakh for goods, ₹20 lakh for services) and there is no other reason to maintain registration, revocation may be approved but the registration could be cancelled again. Make sure you still need the GSTIN.
5. The 90-day window must not have expired. Count from the date of the cancellation order — not the date you learned about it. Check the order date in your GST portal under Notices and Orders.
Once you have filed all pending returns and paid all dues, follow these exact steps:
Step 1: Log into the GST portal. Go to gstin.gov.in and log in with your GSTIN credentials. Note: Even after cancellation, you can log into the portal to file pending returns and apply for revocation. The login credentials remain valid.
Step 2: Navigate to Revocation Application. Go to Services > Registration > Application for Revocation of Cancelled Registration. This menu item only appears when your registration is in cancelled status.
Step 3: Verify cancellation details. The portal shows your cancellation order number, date, and reason. Verify this matches the official order you received. If there is a discrepancy, file a grievance before proceeding.
Step 4: Provide the reason for revocation. In the REG-21 form, you must explain why the registration should be restored. Be specific and factual. Common valid reasons: 'Business was temporarily disrupted due to [reason]. All pending returns for [period] to [period] have now been filed. Outstanding tax of ₹X has been paid. I request revocation to resume regular compliance.' Attach supporting documents.
Step 5: Upload required documents. Depending on the cancellation reason, you may need to upload: (a) Proof that business is operational — current utility bill or rent agreement, (b) Bank statement showing recent business activity, (c) Photos of business premises if cancelled for non-existence at address, (d) Board resolution if the applicant is a company, (e) Returns filing acknowledgments for all filed returns.
Step 6: Sign and submit using DSC or EVC. Company and LLP must use Digital Signature Certificate (DSC). Proprietorships and partnerships can use Electronic Verification Code (EVC) sent to the registered mobile number.
Step 7: Note the ARN. After submission, an Application Reference Number (ARN) is generated. Note this — you will use it to track the application status. The reference number format is AA/YYYY/XXXXXXX.
After you submit your revocation application, the timeline and process is as follows:
Processing by proper officer (30 days): The jurisdictional proper officer reviews your application within 30 days of the filing date. If the application is complete and all conditions are met, the officer approves it and issues an Order for Revocation in Form REG-22. Your GSTIN is immediately restored to active status.
If additional information is needed (Notice in REG-23): If the officer requires more information or documents, they issue a notice in Form REG-23. You have 7 working days to respond with the requested information in Form REG-24. Failure to respond results in rejection.
If rejected (Order in REG-05): If the application is rejected, the officer issues a rejection order in Form REG-05 with reasons. You then have two options: (a) Appeal the rejection within 30 days to the Appellate Authority, or (b) Apply for fresh GST registration if the revocation window has passed.
After approval: Once REG-22 is issued, your GSTIN is restored. You can immediately start issuing GST invoices, filing returns, and claiming ITC. However, you must file any returns that became due during the cancellation period — the portal will show these as pending. File and pay any dues from the cancellation period within 30 days of restoration to avoid further penalties.
At myBillPlease, you can resume invoicing and start generating GSTR-1 data the same day your registration is restored. Simply enter your GSTIN and our system fetches your existing registration details automatically.
Missing the 90-day revocation window is serious but not always terminal. You have two options:
Option 1: Apply for fresh registration (REG-01). Apply for a new GST registration through the standard process. You will receive a new GSTIN. The downside: your previous GSTIN history, ITC balance, and filing records are not carried over. You start fresh. This is the most straightforward path if the cancellation was for non-filing and the business was not operational anyway.
Option 2: Approach the High Court for relief. If there are compelling circumstances — such as a serious illness, natural disaster, death in the family, or a technical glitch that prevented timely filing — you can file a writ petition in the relevant High Court under Article 226 of the Constitution. Several High Courts have condoned delays beyond 90 days in genuine hardship cases and directed the department to accept revocation applications. This requires a lawyer and takes time, but it preserves your GSTIN if that is important for your business continuity.
Also note the 2024 amendment: Through the Finance Act 2024, the government extended the revocation application period from 30 days to 90 days. However, if even 90 days is not sufficient, the taxpayer can apply to the Commissioner (or Additional Commissioner) for a further extension of up to 180 days beyond the original 90-day period. This extended period is granted on case-by-case merits and is not automatic.

Keep all these ready before starting the application. The portal does not allow saving in-progress forms.
Getting your GSTIN revoked is a significant disruption, but restoration is a fresh start. Here is what we recommend doing in the first 30 days after your REG-22 order is issued:
Day 1–3: Update your business partners. Inform key customers and vendors that your GSTIN is active again. If you issued invoices during the cancellation period without GST (treating sales as exempt), review whether those transactions need correction. Consult your CA on how to handle this period's accounting.
Day 1–3: Set up your billing software. Log into myBillPlease with your GSTIN and resume invoice generation. Set up product catalog with correct HSN codes and GST rates. This ensures all future invoices are compliant from day one.
Day 4–15: File any returns due during cancellation period. The portal may show pending returns from the cancellation period. File GSTR-1 and GSTR-3B for those months with appropriate data. If there were no transactions during the cancelled period, file nil returns.
Day 15–30: Reconcile ITC. Check GSTR-2B for the restoration period to understand what ITC is available to you. Run the GST calculator to project your next month's liability and ensure you have the cash available.
Ongoing: Enable automated reminders. The most important action is to never miss a due date again. myBillPlease sends WhatsApp and email reminders 7 days and 1 day before every GST filing deadline. Enable these immediately after resuming.
Once your registration is revoked, myBillPlease gets you invoicing again in minutes. Automated reminders mean you will never miss a filing deadline again.
