How to Use the Deadline Tracker

  1. Pick notice type — Income Tax or GST. The section dropdown filters accordingly.
  2. Select the section / form. The reply window auto-populates based on statutory norms (30 days for most, 7-15 days for Section 148A(b) and certain GST forms). If you don't know the section, use the Notice Section Identifier tool first.
  3. Enter notice received date. Defaults to today. If you received the notice earlier, set the actual receipt date — the deadline is computed from this.
  4. Override the reply window if needed. The notice itself states the exact reply window — if it differs from the statutory default, enter the actual window from the notice.
  5. Click Calculate. Get the exact deadline date, urgency rating, days remaining, milestone timeline, and calendar export options.
  6. Add to your calendar. One-click Google Calendar URL, or download the .ics file for Apple Calendar / Outlook / other apps. Four advance reminders (14, 7, 3, 1 day) are built in.
  7. Engage Patron. Free 15-min review call to validate the deadline + plan the response strategy.

Important: The deadline shown by this tool is a statutory default estimate. The actual deadline applicable to your notice is what is stated in the notice itself. Always verify the exact deadline from the notice text and engage a CA for confirmation.

Note on Sundays and Holidays: Under the General Clauses Act, 1897, if the last day for response falls on a Sunday or notified public holiday, the deadline extends to the next working day. However, the e-Proceedings / GST portal does not always auto-adjust — best practice is to file 1-2 working days before the calculated deadline.

What Happens If You Miss the Deadline

Income Tax Consequences

  • Section 142(1) non-response: Escalation to Section 143(2) scrutiny; eventual Section 144 best-judgment assessment with 270A penalty
  • Section 143(2) non-response: Section 144 best-judgment assessment — AO makes adverse computation; 50 percent under-reporting penalty likely
  • Section 148A(b) non-response: Direct Section 148 reassessment without further opportunity; ex-parte reassessment risk
  • Section 148 non-response: Ex-parte reassessment with full income addition; Section 271(1)(c) / 270A penalty
  • Section 156 non-payment: Section 220(2) interest at 1 percent per month starts (after 30 days); recovery proceedings under Section 226 (bank attachment, third-party recovery)
  • Section 270A non-response: Ex-parte penalty order at maximum 50 percent or 200 percent rate; Section 270AA waiver becomes unavailable

GST Consequences

  • ASMT-10 non-response: Escalation to DRC-01 under Section 73 / 74; 10 percent / 100 percent penalty exposure begins
  • DRC-01A non-response: Direct DRC-01 SCN under Section 74; 15 percent early-payment benefit lost
  • DRC-01 non-response: Ex-parte DRC-07 order with full demand + penalty (10 percent for Section 73, 100 percent for Section 74)
  • DRC-07 non-appeal within 3 months: Order becomes final and unappealable except in limited circumstances; recovery proceedings under Section 79 (bank attachment, property attachment)
  • GSTR-3A non-compliance: Suspension or cancellation of GST registration; reversal of ITC for buyers
  • Section 76 non-payment: 18 percent p.a. interest accrual continues; recovery action under Section 79

Recovery Proceedings. Once recovery starts under Section 226 (IT) or Section 79 (GST), the department can attach bank accounts, recover from debtors, and even arrest in extreme cases. Always reply on time, even with an interim reply requesting extension — silence is the worst response.

Frequently Asked Questions

The reply deadline equals the notice issuance date plus the statutory reply window specified in the notice. For most Income Tax notices the standard window is 30 days from the date of service of the notice. Some sections have shorter windows: Section 148A(b) show-cause notice is typically 7 to 15 days as specified, and certain rectification or summary procedures may have 15 days. The notice itself states the exact reply deadline — always verify the deadline from the notice text rather than relying solely on calculated estimates. If the deadline falls on a Saturday, Sunday, or public holiday, it generally extends to the next working day, but this varies by department practice.
Section 143(2) scrutiny notices have a 30-day reply window from the date of service. The first reply on the e-Proceedings portal acknowledges the notice and begins the formal scrutiny process. Subsequent rounds of questions and document requests are typically given 7 to 15 days each, but these are managed within the overall faceless assessment timeline. The entire scrutiny assessment must be completed within 12 months from the end of the assessment year, so taxpayers should expect multiple interactions within the year. Missing any deadline can trigger best-judgment assessment under Section 144.
GST DRC-01 show-cause notices issued under Section 73 (non-fraud) or Section 74 (fraud) typically allow 30 days for reply from the date of service. The reply must be filed in form DRC-06 on the GST portal under Returns greater than User Services greater than Notice and Demand. The 30-day period is statutorily prescribed under Rule 142 of the CGST Rules. After receiving the reply, the proper officer must pass the final order in DRC-07 within 3 years (for Section 73) or 5 years (for Section 74) from the due date of annual return. Missing the 30-day window leads to ex-parte order in DRC-07 with full demand and 100 percent penalty under Section 74.
Yes — extensions are routinely granted upon written request showing reasonable cause. For Income Tax notices, file an extension request on the e-Proceedings portal explaining the cause (medical emergency, complex documentation, CA unavailability). For GST notices, file the extension request on the GST portal. Typical extensions granted are 7 to 15 days; longer extensions require stronger justification. Always file the extension request BEFORE the original deadline expires — post-expiry requests are often denied. Patron drafts and files extension applications with appropriate supporting documents.
Income Tax consequences: missing Section 143(2) reply triggers best-judgment assessment under Section 144 with adverse computation and 50 percent under-reporting penalty. Missing Section 148 reply leads to ex-parte reassessment with full income addition. Missing Section 156 demand notice deadline starts Section 220(2) interest at 1 percent per month and recovery proceedings under Section 226 (bank attachment, third-party recovery). GST consequences: missing DRC-01 reply leads to ex-parte DRC-07 order which becomes recoverable. Missing DRC-07 appeal deadline (3 months) makes the order final and unappealable except in limited circumstances. Always reply on time, even with an interim reply requesting extension.
This tool generates a one-click Google Calendar event URL after you enter the notice details. Click the Google Calendar button after calculation; a pre-filled event opens in a new tab with the deadline date, time, and description. Click Save in Google Calendar to add it. The event includes default reminders at 14, 7, 3, and 1 days before the deadline. For other calendar apps, use the iCalendar (.ics) download option which works with Apple Calendar, Outlook, Thunderbird, Yahoo Calendar, and most other calendar applications. Both options include the four advance reminders.
iCalendar (.ics) is a standard calendar file format supported by all major calendar applications (Apple Calendar, Microsoft Outlook, Mozilla Thunderbird, Yahoo Calendar, ProtonMail Calendar, etc.). After clicking the Download .ics button, the file downloads to your device. Open it by double-clicking — your default calendar app will prompt to import the event. The .ics file generated by this tool includes the event title, deadline date, full notice description, and four advance reminders (14 days, 7 days, 3 days, and 1 day before). Once imported, you can edit the event in your calendar app like any other event.
A 7-day reply window — typically seen in Section 148A(b) show-cause notices, certain GSTR-3A non-filing notices, and rectification proceedings — is critical urgency. Begin work immediately: (1) Day 1 — verify DIN, read notice, engage CA, identify documents required; (2) Days 2 to 4 — compile documents, reconcile data, draft response; (3) Days 5 to 6 — review with CA, finalise; (4) Day 7 — file response, take acknowledgement. Most 7-day notices cannot accommodate extension requests — the response must be filed within the original window. For Section 148A(b), failure to respond within 7 to 15 days leads directly to Section 148 reassessment notice without further opportunity.
Section 220(2) interest at 1 percent per month accrues on tax demand under Section 156 that remains unpaid after 30 days from the date of demand notice. The interest is simple interest, calculated on the principal demand (tax plus 234A/B/C interest), and continues until full payment. For example, ₹10 lakh demand unpaid for 90 days attracts approximately ₹20,000 additional interest (2 months times 1 percent times ₹10 lakh). The interest does not compound. Patron Accounting files Section 220(6) stay applications along with appeals to stop the accrual clock during legitimate disputes.
In general, if the deadline falls on a Saturday, Sunday, or notified public holiday, it is extended to the next working day under the General Clauses Act, 1897. However, this is not automatic on the e-Proceedings or GST portal — the system may still show the deadline as expired. Best practice: file the response one to two working days before the calculated deadline to avoid any portal-related issues. If you must file on the deadline day, file before 6 PM IST to allow for technical glitches. Patron handles all deadline-day filings with backup paper submission via registered post for critical cases.
This tool calculates one deadline per use. For multiple notices, run the tool separately for each notice and add each calendar event to your calendar app. The Google Calendar and iCal exports use unique event IDs, so adding multiple events does not overwrite earlier ones. Each event includes the notice section and demand amount in the title, making them easy to distinguish in your calendar. Patron offers a deadline management service for businesses with multiple ongoing notices — we maintain a master tracker and send weekly reminders.
All deadlines are computed using Indian Standard Time (IST, UTC plus 5:30) at the day level. The Income Tax e-Proceedings portal and GST portal both operate on IST. A deadline date such as 15 June 2026 means 11:59 PM IST on that date is the cutoff. The Google Calendar event URL uses your local time zone for display, but the underlying date is set as an all-day event so it appears correctly regardless of viewer timezone. The .ics file uses VALUE=DATE for the deadline, ensuring the all-day event appears on the correct calendar date for any timezone.
No. The tool's output is advisory only — it computes the deadline based on standard statutory reply windows. The actual deadline applicable to your notice is what is stated in the notice itself, considering any specific deviation, extension granted, or service-of-notice issues. Always verify the deadline from the notice text and engage a Chartered Accountant for the final calculation. Patron Accounting offers free 15-minute notice review calls and end-to-end notice representation including deadline management, response drafting, filing, and hearing representation across Pune, Mumbai, Delhi, Gurugram, Hyderabad, Chennai, Bangalore, Kolkata and pan-India digitally.
