There is no single reply deadline or defence that applies to every Indian income-tax penalty notice. Verify the notice, identify the tax year and allegation, follow the deadline shown for that proceeding, and submit a factual response with supporting records through the official e-Filing portal when the proceeding is available there.
First identify what the notice requires
A penalty show-cause notice is an opportunity to explain why a penalty should not be imposed; it is not the same as a final penalty order. Read the notice itself and the related portal record before drafting a response. Record the taxpayer name and PAN, issuing authority, document reference and Document Identification Number (DIN), cited provision, tax or assessment year, date of service, reply deadline, and current proceeding status. The Income Tax Department describes a DIN as a unique number for communications from tax authorities.
Use the Department’s e-Filing portal to locate the item in the relevant pending-action or e-Proceedings area and compare it with the notice you received. If you cannot find the notice or doubt its authenticity, use the Department’s notice-authentication facility and official contact channels. Do not rely on links or payment instructions in an unverified message.
Check which law and tax period apply
Do not choose a reply template solely because it is described as being under a particular Act. Check the tax year and provision cited in the notice. The Income Tax Department’s transition guidance says that specified pending proceedings, and proceedings initiated from 1 April 2026 concerning tax years beginning before 1 April 2026, may continue under the Income-tax Act, 1961. The Income-tax Act, 2025 applies to relevant later tax years subject to those transition rules. A notice prepared after the new Act’s commencement does not, by itself, move an older tax year into the new regime.

There is no universal reply period established for all penalty show-cause notices. Use the due date and instructions in the actual notice, then check the portal to confirm the response window is still open. If the dates or instructions conflict, seek clarification promptly rather than assuming the longer period applies.
The Department’s e-Proceedings FAQ says that, while a proceeding is open, portal submission may become unavailable during the final seven days before the proceeding’s limitation date, until 6 p.m.; submission may also be closed where there is no limitation date. This is a portal-window rule described by the Department, not a general extension of the deadline in your notice.
The often-quoted 15 days applies to a different situation: the Department’s guidance for a defective-return notice under section 139(9) allows 15 days from receipt, or the alternative period specified in that notice, to correct the return. Do not treat that as the deadline for a penalty response.
If the proceeding offers an adjournment request, you may use that facility where appropriate, but do not assume the deadline has changed unless the extension is confirmed.
Build a focused reply to each allegation
Section 274 of the Income-tax Act, 1961 provides for a show-cause notice and a reasonable opportunity to be heard before a penalty is levied. The Income Tax Department’s Finance Bill 2026 explanatory material describes the requirement this way: “no penalty shall be levied unless the assessee is given a reasonable opportunity of being heard.” Use the opportunity to answer the specific case made in your notice, rather than sending a generic denial.
Organize the response around the notice
- Identify the notice, proceeding, tax year, and provision so the response is associated with the correct matter.
- Answer each allegation in the order presented. Separate facts you accept from facts or conclusions you dispute.
- Explain the relevant events and any discrepancy, and state clearly what outcome you are asking the authority to consider.
- Refer to supporting documents by name and explain what each one demonstrates. Keep the explanation consistent with the return, assessment record, and other information already submitted.
Attach evidence that supports what you say
Depending on the allegation, relevant records may include the return and computation, assessment order, tax-payment or withholding records, account statements, invoices, reconciliations, or earlier correspondence. Include only material that supports the facts in your reply, and check that each attachment is legible and relates to the correct tax year. The portal supports response text and attachments, although the fields available vary by proceeding.
Avoid unsupported admissions and blanket denials. If a fact is uncertain or a record is missing, describe that accurately rather than presenting an assumption as established fact.

- Open the relevant notice or proceeding in the Income Tax Department’s e-Filing portal and select the response action shown for it.
- Enter the reply in the available fields and attach the supporting documents. Check the notice reference, tax year, response text, and attachments before submission.
- Submit the response and save a copy of the final text, every attachment, the acknowledgement or transaction record, and the updated portal status.
The Department’s e-Proceedings FAQ says a submitted response cannot be edited or withdrawn through the portal. Review it carefully before filing; if you later discover an error, use the available official channel to ask how to address it rather than assuming the original submission can be replaced.

A response to a show-cause notice and an appeal against a final penalty order are different procedural steps. The Department’s Form 35 manual gives a general 30-day appeal period for an assessment or penalty appeal, measured from service of the related notice of demand. The actual order and governing law control: verify the appeal forum, filing route, applicable fee, and limitation trigger from the order and current portal instructions. Do not treat the show-cause reply deadline as the appeal deadline.
The appropriate response, potential penalty, and available grounds depend on the notice, alleged conduct, tax period, assessment record, and service facts. Where the allegation is complex or the amount at stake is significant, an Indian tax professional or chartered accountant can help assess the records and procedural options; the portal also supports an authorized representative.
