Act immediately, but do not assume that the date you opened the envelope is the legal service date. Compare the notice’s issue date and stated delivery method with postal, email, GST portal and office records. Section 169 of the Central Goods and Services Tax (CGST) Act, 2017 uses channel-specific deemed-service rules. Preserve the evidence, prepare a reply to the allegations, and request a hearing or adjournment in writing if you need time. The correct response deadline comes from the notice and the provision under which it was issued, not from a universal GST rule.
First, secure the notice and the deadline
A late-arriving GST show-cause notice can create two separate problems: proving when it was legally served and answering the tax allegations before the authority acts. Deal with both in parallel. A service dispute should not stop you from filing a protective, substantive response.

- Save the complete file. Download the notice, every annexure, demand calculation and cited document from the official GST channel. Keep the paper notice and envelope in their original condition; make working copies for marking up.
- Record the notice particulars. Note the form, reference number or ARN, issue date, issuing authority, statutory section, financial year or tax period, allegations, tax/interest/penalty amounts, stated reply date and hearing details.
- Check every channel now. Review the GST common portal notice area, the registered GST email account, spam or quarantine folders, postal tracking and internal mail records, even if you first saw only a paper copy.
- Build a dated chronology. Separate the issue date, dispatch date, portal-availability date, email timestamp, tender or delivery date, date you actually discovered the notice and deadline printed in it.
- File protective requests promptly. If the stated deadline is close or has passed, explain the actual discovery date and attach the supporting records. Ask in writing for adequate time, an adjournment or permission to file a reply, while also addressing the allegations as far as possible.
Use the filing route specified for that notice. Keep the electronic acknowledgment, ARN, uploaded PDF and any email or physical-submission proof.
How GST law determines the service date
Section 169 of the CGST Act lists several ways a decision, order, summons, notice or other communication may be served. The legal date depends on the method used and the evidence for that method; it is not automatically the day you opened an envelope.
#1 Best Overall
| Service channel | What to check | How the date is treated |
|---|---|---|
| Personal delivery or tender | Officer’s delivery record, acknowledgment, recipient name, date, time and place | Service is generally deemed on the date the communication is tendered. |
| Registered post, speed post or courier | Dispatch register, article number, tracking history, delivery attempt, proof of delivery, returned-mail markings and the address used | Section 169 provides a deemed-receipt rule at expiry of normal transit time unless the recipient proves otherwise. The envelope-opening date alone is not the test. |
| Message sent to the email address supplied at GST registration or later amended, complete headers, timestamps, delivery or bounce status and access problems | The authority may rely on the registered email channel. Preserve the message and technical records showing when it was sent and received or blocked. | |
| GST common portal | Notice listing, downloadable file, reference number, availability or upload timestamp and portal acknowledgment | Availability through the statutory portal channel can be relevant even if no paper copy was noticed. |
| Newspaper publication | Publication date, newspaper edition, clipping or certified copy and the circumstances said to justify publication | Section 169 recognizes publication as a method; the publication date is material. |
| Affixture in specified circumstances | Officer’s report, location, date, photographs or witness details and evidence that earlier methods were not practicable | Where the statutory fallback is properly used, service is deemed on the date of affixture. |
Section 169(2) states: Every decision, order, summons, notice or any communication shall be deemed to have been served on the date on which it is tendered or published or a copy thereof is affixed in the manner provided in sub-section (1).
The distinct postal rule in section 169(3) must be considered separately. Whether a particular service was valid requires the actual records, the applicable provision and the facts; late physical delivery does not automatically invalidate a notice.
Records to collect before challenging or answering service
Keep unaltered originals and create a working folder with a clear file name for each item. The following evidence connects the notice to the statutory channel and date:
- The full notice, all annexures, demand calculations and documents cited by the officer.
- Original envelope, courier label, postal article number, tracking history, proof of delivery, returned-mail markings and any dispatch record available from the authority or courier.
- GST portal notice listing, downloaded file, notice reference or ARN, and any system record showing when the document became available.
- The email sent to the GST-registered or later-amended address, including full headers, timestamps, delivery or bounce notices, spam/quarantine records and evidence of access problems.
- GST registration particulars and amendment acknowledgments showing the principal place of business and registered email on the relevant dates.
- Internal mail logs, receptionist or authorized-representative handover records, staff leave, office closure or relocation evidence, and the date the notice was first discovered.
- Any hearing notice, earlier reply, adjournment request, portal submission acknowledgment and communication with the issuing officer.
Do not alter metadata, overwrite the original PDF or discard a returned envelope. If several people handle GST correspondence, obtain short signed statements identifying who received, forwarded or first located the notice.

Identify the exact notice and its reply route
“GST notice” is not one procedure. The form, statutory section, tax period and stage determine what you must file and by when. Read the heading and annexures rather than relying on an email subject line.
Details that control the response
- Form name and reference number, issuing officer and jurisdiction.
- Section or rule cited, financial year and tax periods covered.
- Alleged facts, tax computation, interest, penalty and documents relied upon.
- Reply deadline, hearing date and instructions about portal, email or physical filing.
- Whether the document is a show-cause notice, a statement or summary, a hearing communication, or an order already passed.
When Rule 142 and DRC forms are involved
For covered demand proceedings, rule 142 provides for an electronic summary in form DRC-01 and a reply in DRC-06. Check the current rule and portal workflow for your notice; do not assume every GST communication uses these forms.
DRC-06 provides fields for the notice reference and date, financial year, written reply and uploaded documents. It also includes an option to indicate a personal hearing. Upload a focused reply with indexed annexures, and retain the generated acknowledgment and the exact files submitted.
Prepare a response that protects both substance and service objections
Address the tax allegations, not only lateness
Start with a concise chronology and a paragraph explaining when and how you actually received or discovered the notice. Then answer each allegation under a numbered heading. Reconcile the officer’s figures with returns, invoices, payment records, e-way bills, ledgers and prior correspondence. Identify documents that are unavailable and explain why, instead of leaving a point unanswered.

State the authority’s asserted channel, the date shown by its record, the date your records show and the evidence attached. Ask the officer to provide the dispatch, delivery, portal or email record if it has not been supplied. Avoid claiming that the notice is void merely because the envelope arrived late; the legal result depends on section 169 and the facts.
Request time, documents or a hearing expressly
Section 75(4) requires an opportunity of hearing when the taxpayer requests one in writing or when an adverse decision is contemplated. Section 75(5) permits an adjournment for sufficient cause, with reasons recorded, subject to the statutory limit on adjournments. In your filing:
Rank #4
- State the date you actually received or found the notice and the practical reason for the delay.
- Attach the envelope, tracking, portal, email or internal records that support that statement.
- Request a specific amount of additional time or a new hearing date, rather than asking vaguely for “more time.”
- Ask for copies of missing relied-upon documents and a chance to respond to any new material.
- Select the personal-hearing option in DRC-06 where applicable and repeat the request in the written covering letter.
Section 75(6) requires an order to set out relevant facts and its basis. Section 75(7) limits the confirmed demand to the amount and grounds stated in the notice. Your reply should therefore identify any proposed demand that exceeds the notice or introduces a new ground.
Submit correctly and preserve proof
- Use the portal or other route named in the notice. If DRC-06 applies, complete the notice reference, financial year, written reply and document-upload fields accurately.
- Upload searchable PDFs with descriptive names and an index. Keep the same files locally, including a copy of the final text.
- Submit before the printed deadline if possible. If that is impossible, submit the late-receipt explanation and substantive response at once rather than waiting for a ruling on service.
- Download the acknowledgment, ARN, submission timestamp and any generated receipt. Take a screenshot of the portal status and keep confirmation emails.
- If the portal fails, record the date, time, error message and support ticket, then use the alternative filing method permitted by the notice and send a written explanation.
A portal draft or an email sitting in an outbox is not proof of filing. Verify that the status says submitted or filed and that attachments can be opened.

Best Value

- Comes with secure packaging
- Helpful in various ways
If an adjudication decision or demand order has already been communicated, the appeal timetable is a separate urgent issue. The GST Portal FAQ describes a general period of three months from communication for a taxpayer or unregistered person to appeal an adjudication decision or order, with the authority able to condone up to one additional month when sufficient cause prevented timely filing. Confirm the current rule, form and jurisdiction for your order and obtain case-specific advice quickly. An appeal deadline is not the same as a show-cause-notice reply deadline.
Common mistakes and how to avoid them
- Counting from envelope opening only: compare all statutory channels and the postal deemed-receipt rule.
- Checking only paper mail: inspect the registered email and GST portal records.
- Sending a service objection with no tax response: answer the allegations protectively while reserving the service issue.
- Assuming every notice is DRC-01/DRC-06: follow the form and section actually cited.
- Ignoring the registered-address history: preserve registration and amendment records for the relevant date.
- Missing the hearing request: make it explicit in writing and select the portal option where available.
- Relying on an unverified upload: retain the acknowledgment, timestamp and final documents.
- Treating a late notice as automatically invalid: validity depends on the statutory method, evidence and applicable law.
When professional help is warranted
Obtain prompt advice from a qualified GST practitioner or tax lawyer when the notice involves a large demand, multiple years, allegations of fraud or suppression, disputed portal records, an already-passed order, or a possible appeal. Provide the complete chronology and unaltered evidence rather than only the late envelope. A professional can assess the governing section, service record, reply strategy and any appeal or condonation application; no general checklist can decide those questions for a particular case.
Legal and procedural limits to keep in mind
There is no universal GST reply period for every show-cause notice. The exact time comes from the notice and its governing section or rule. The CGST Act’s service provisions also do not make every late-delivered notice invalid. Editions of rules and forms, as well as portal screens, can change, so verify the current text and workflow when filing. The records, chronology and written requests described above put you in the strongest position to preserve your response rights while the service question is examined.
