A GST registration cancellation does not, by itself, wipe out tax, dues or compliance obligations for earlier periods. First identify the notice’s form, legal provision, tax periods, service date and deadline; then reconcile the allegations against your records and reply through the process that applies to that notice. A cancellation show-cause reply and a later demand reply are different procedures, so do not choose a form based only on the fact that your registration is cancelled.
Why a notice can arrive after GST cancellation
Cancellation ends a registration from its effective date; it does not automatically settle everything connected with periods before that date. Section 29(3) of the Central Goods and Services Tax Act, 2017, says that cancellation does not affect liability to pay tax or other dues, or to discharge an obligation under the Act or rules, for a period before cancellation—even if the amount is determined after cancellation. The timing of the cancellation alone is therefore not a sufficient answer to a notice about an earlier tax period.

That does not mean every demand is correct. The authority still needs to identify the relevant period, legal basis and calculation, and you can dispute a factual or legal error with supporting records. The key distinction is between the date your registration ended and the period to which the alleged tax or obligation relates. Check the effective cancellation date in the order; it may not be the same as the date the order was issued.

Identify what kind of notice you received
“GST notice” is not a single procedure. Read the complete notice, every annexure and the corresponding portal record before drafting. Note the exact form number and section or rule cited, the periods involved, the amount breakup, how and when it was served, the response deadline, any hearing date and the instructed submission channel.
#1 Best Overall
| What the document may concern | What to look for | Response route to verify |
|---|---|---|
| Cancellation show-cause proceeding | REG-17 and the stated reasons for proposed cancellation | The Telangana GST Department’s November 2025 registration handbook describes a REG-18 reply within seven working days for this process. Do not transfer that deadline to a different notice. |
| Demand proceeding | The statutory section, tax period, calculation and whether an electronic DRC-01 summary accompanies the notice | Under Rule 142, covered demand notices have an electronic DRC-01 summary; DRC-06 is the reply form for notices whose summary has been uploaded in DRC-01. Verify the notice and current portal instructions. |
| Assessment of a person whose registration was cancelled | Whether section 63 is cited and the basis for treating the person as liable to tax | Section 63 provides for best-judgment assessment in relevant cases and an opportunity of being heard. Check the cited provision and the notice’s response instructions. |
| Short-paid tax or wrongly availed or used input tax credit | The specific provision, tax periods, transaction details and method used to quantify the alleged amount | Different demand tracks have different legal conditions. Section 74A is also present in current Act materials for relevant periods; older section references should not be assumed to apply universally. |
| Final-return follow-up or request for clarification | Whether the notice actually concerns GSTR-10, a missing filing, or a particular information request | Respond to the stated issue and channel. A final-return issue, clarification request and tax demand are not interchangeable. |
The forms and procedures in this table are examples of distinct routes, not a substitute for reading the notice. A REG-17 cancellation proceeding is not the same as a later tax demand, and REG-18 and DRC-06 are not interchangeable. If the form, statutory provision and portal record appear inconsistent, preserve the documents and obtain qualified advice promptly rather than guessing which route applies.
Record the dates, periods and amounts before writing
Make a one-page notice summary for your own use. Capture each of the following exactly as it appears in the notice or portal:
- Form number, issuing officer and jurisdiction.
- Legal section or rule cited, including any provision cited in an annexure.
- Each tax period alleged, and whether it falls before, on or after the effective cancellation date.
- Notice issue date, actual service date and method of service; keep the email, portal entry or physical delivery record.
- Reply deadline, hearing date and submission route.
- The claimed amounts split into tax, interest, penalty, late fee and any other component.
- Every calculation, relied-upon document and attachment referred to by the authority.
Do not work from only a reminder email or a screenshot of the first page. Download and preserve the complete notice, annexures, portal acknowledgment and service information. Compare portal and email or physical copies; note any discrepancy without silently choosing one version. Keep the cancellation order and application or order history with the effective date clearly marked.

Build a period-wise reconciliation
Before deciding whether to admit or dispute an amount, recreate the calculation for each period in the notice. A useful working table separates the authority’s claim from your records and keeps principal tax distinct from additions:
| Tax period | Notice allegation or calculation | Return, ledger or source record | Tax or amount already paid | Difference and explanation | Evidence to attach |
|---|---|---|---|---|---|
| Enter the period named in the notice | Record the allegation and amount as stated | Identify the relevant return, ledger entry, invoice or other record | Record payment and reference, if any | Show your calculation and the reason for any mismatch | List the supporting document by name |
Use a separate calculation for tax, interest, penalty and late fee rather than combining them into one unexplained total. Compare the authority’s figures with returns and amendments, electronic cash and credit ledger entries, challans, payment references, invoices, credit or debit notes and relevant transaction records. If the notice concerns stock or cancellation-related liability, check whether stock records and the relevant cancellation disclosures bear on the allegation.
If your records do not allow you to reconcile a figure, say what you checked and identify what remains unexplained. Do not invent a payment, invoice or calculation to fill a gap. If you believe the notice omits a document or uses a figure that cannot be verified from the material supplied, identify that specific issue and request the information or opportunity needed to answer it.
Draft a point-by-point reply
Answer allegations in the order they appear. For each one, state whether you admit it, admit only part of it, or dispute it. Then give the relevant facts, cite the attached records, show the calculation where a number is involved and state the specific relief you seek. A bare denial gives the authority little to evaluate; a general statement that the business closed or registration was cancelled does not answer an allegation about an earlier period.
A clear reply can be organized as follows:
- Identify the proceeding. Give the notice number and date, form, cited provision, tax periods and your registration details as shown in the notice.
- State the procedural position. Record when and how you received the notice and confirm the response or hearing route you are using. If a material attachment was not supplied or the service record is disputed, explain the issue factually.
- Respond allegation by allegation. Quote or summarize each allegation briefly, then state admitted, partly admitted or disputed and give the reason.
- Show the reconciliation. Explain your period-wise calculation and point to the corresponding return, ledger, invoice, payment record or other exhibit.
- Ask for a defined outcome. For example, specify the amount or allegation you say should be dropped or corrected, or request a hearing or particulars needed to respond. Do not make a broader claim than your evidence supports.
- Index the attachments. Use numbered exhibits and make the exhibit references in the reply match the uploaded documents.
Keep the tone factual and professional. Avoid arguing that cancellation automatically removed all prior liability, and avoid conceding a disputed amount merely because the registration has ended. Payment, admission of liability, a request for time and a challenge to the merits are distinct decisions; understand the calculation and procedural consequences before choosing among them.
File through the correct channel before the applicable deadline
Use the form and submission channel specified for the proceeding, and verify the current portal instructions for that form. The November 2025 Telangana GST Department handbook describes REG-18 as the response to a REG-17 cancellation show-cause notice, with seven working days for that cancellation process under Rule 22. Rule 142 covers electronic DRC-01 summaries for specified demand notices and the DRC-06 reply route for notices whose summary has been uploaded there. These procedures do not establish a universal deadline for every post-cancellation notice.
Rank #4
Use the deadline stated in your actual notice as urgent. If the notice is unclear about when time starts, the applicable calculation of days, or the route for filing, do not assume that the seven-working-day REG-18 period applies. Ask the issuing office or a qualified GST professional promptly, while preserving proof of service and preparing the response. A hearing date is also important even if you have filed written submissions.
- Sign in to the GST Portal and open the relevant notice or proceeding record; confirm the form, reference number and available response action.
- Prepare the reply and supporting files in a readable format, with filenames that match your exhibit index.
- Complete the prescribed response form and submit through the route that applies to that notice; do not substitute another form because it seems similar.
- Save the final reply, each uploaded attachment, portal acknowledgment or reference number, and any hearing details.
- Check that the submission appears against the correct proceeding and retain a dated copy outside the portal.
The GST Portal’s cancellation guide describes tracking registration applications and confirmations. Its cancellation manual also describes providing stock value and associated tax liability for relevant cancellation reasons, offsetting liability from the cash and/or credit ledger, submitting and tracking the ARN. Those cancellation entries may help explain a later allegation, but their relevance depends on what the notice actually raises.

Revocation is a route to seek restoration of registration in eligible cases; it does not replace an answer to a separate demand. Under current Rule 23, as reflected in official CBIC Tax Information Portal text, a person whose registration was cancelled by the proper officer on the officer’s own motion generally has a 90-day period to apply for revocation using REG-21. A specified senior officer may allow a further extension not exceeding 180 days where the stated conditions, including sufficient cause, are met. Confirm the applicable rule version, eligibility and portal status before relying on these periods.

Where cancellation followed failure to file returns, prescribed returns and relevant dues must be addressed before applying for revocation. If the department issues a REG-23 clarification notice in the revocation process, the response is REG-24 within seven working days. That is a clarification step in the revocation route, not a substitute for a reply to an independent tax demand.
Separately, the Telangana GST Department’s November 2025 handbook summarizes section 45 as requiring a GSTR-10 final return generally within three months from the date of cancellation or the cancellation order, whichever is later. It also lists categories that are not required to file. Because the applicable category and current law matter, check whether GSTR-10 applies to you and whether the notice actually concerns that obligation; do not infer a separate demand from the fact of cancellation alone.
Documents to collect before filing
Gather the documents that address the periods and allegations in your specific notice. Not every item will apply in every case:
- The full notice, annexures, portal copy, proof of service, prior reminders and any relied-upon material.
- Cancellation application and order history, the cancellation order and the effective date.
- Returns and amendments for the periods named, together with filing acknowledgments.
- Electronic cash and credit ledger extracts, challans, payment references and records of prior demand adjustments.
- Sales and purchase invoices, credit and debit notes, and e-way or other transaction records where relevant to the allegation.
- Stock records if the notice raises stock or cancellation-related liability.
- Earlier correspondence, audit or assessment records and explanations already submitted.
- A dated chronology and the period-wise reconciliation, with each figure tied to a source record.
Organize files so the officer can move from an allegation to your answer and then to the evidence without having to infer which document supports which statement. Keep original records and a saved copy of what you upload.
When professional help is especially important
Consider prompt review by a GST practitioner, chartered accountant or tax lawyer if the notice alleges evasion, covers several periods, involves significant liability, gives a near-term deadline, raises a complex input tax credit issue, or you cannot identify the correct statutory route. Professional review can also help where the notice and portal record differ, a hearing is scheduled, or a missed filing may affect revocation or the final-return position. Bring the complete notice and attachments, cancellation order, service proof, returns, ledgers, payment records and your draft reconciliation; a summary without source documents can make it harder to assess the issue.
Quick Recap
Common mistakes to avoid
- Treating cancellation as a complete defence. Section 29(3) expressly preserves obligations and liabilities for pre-cancellation periods.
- Using the wrong reply form. REG-18 relates to the described cancellation show-cause route; DRC-06 relates to covered demand notices with a DRC-01 summary.
- Applying one deadline to every notice. The seven-working-day period described for REG-17 is not a universal post-cancellation response period.
- Ignoring the effective date. The cancellation order date and effective date can differ, and the notice may concern a period on either side of that effective date.
- Sending a generic business-closed explanation. It does not resolve a period-wise tax, return, payment or records allegation.
- Confusing remedies. Revocation seeks restoration in eligible cases; it does not itself answer a separate demand.
- Submitting without proof. Save the reply, attachments, acknowledgment and hearing information so you can establish what was filed and when.
