GST Notice Reply Deadline Calculator

Find the usual reply or appeal window for a GST notice from its date. The date printed on your notice always wins.

Which notice or order?

Date of the notice or order (optional)

Pick the date from the calendar or type it as year-month-day

Date it was served or communicated (optional)

If you know it. Many windows run from the date of service

Date stated on the notice (optional)

If the notice itself gives a last date for reply, enter it here. That date is the one that counts

How this works

Choose the notice or order and enter its date (and the date of service if you know it).
A date printed on the notice always wins over the standard window, so enter it if there is one.
The standard windows and their provisions come from our notice catalogue. A time limit for the department is shown only if our expert team has verified it.

These dates are built into our tool and are not checked one by one. Please confirm them on the official portal.

What it does: Works out the last date to reply to a GST notice from the date it was served and the kind of notice it is.
The rule it rests on: The time to reply is set by the provision the notice is issued under, and rule 142 of the CGST Rules, 2017 governs the demand notice and its reply in the DRC forms. Where the notice itself names a date, that date governs; the tool says which of its windows are registered defaults rather than approved rows. Official source: CGST Rules, 2017, rule 142 (notice and order for demand)
Checked on: 11 November 2026. Where a figure the tool shows is still to be verified by our expert team, the tool says so instead of showing it.
Next step: Not sure which notice you hold? The decoder names it and lists what a reply contains. Notice decoder
