The reply goes on a different form.

Because that is how it works, and it is the single most common mistake in the material you will find elsewhere. ASMT-10 is the officer's form — the notice sent to you. Your reply is filed on ASMT-11, "Reply to the notice issued under section 61 intimating discrepancies in the return", under CGST Act s.61 read with CGST Rule 99. A letter headed with the notice number tells the department you have not understood what you were sent.

Because this document lands on a proper officer’s desk, and the wording carries statutory weight. You choose which situation is true and the letter states it in the terms the rule uses. If none of the listed situations fits yours, the tool tells you so rather than producing a confident letter about facts that are not yours — that case genuinely needs a professional.

It is the covering document. The reply itself is filed on the portal against the notice that was issued, and the supporting records — invoices, credit notes, returns, challans — are what actually resolve the discrepancy. The letter states your position clearly and puts it on the record; it does not replace the filing.

No. The details are sent to our server only when you press download, used to typeset the PDF, and returned to you immediately. Nothing you type is saved. We separately count that a document of some kind was generated — no account, no IP address, nothing from the document — so we can tell whether this tool is used at all.

A notice arrives on one form and is answered on another, and getting that pairing right is most of the job. A scrutiny notice under CGST Act s.61 read with CGST Rule 99 arrives as ASMT-10 and is answered on ASMT-11. A registration query arrives as REG-03 under CGST Rule 9 and is answered on REG-04. A show cause notice proposing cancellation arrives as REG-17 and is answered on REG-18 (CGST Rule 22(2)). Revocation of a cancellation already ordered is applied for on REG-21, and voluntary cancellation on REG-16.

It depends on the notice, and the windows are not counted the same way. ASMT-10 carries not exceeding thirty days from service of the notice, as specified in the notice itself. REG-03 carries within seven working days from the date of receipt of the notice — working days there, which is not the same as thirty calendar days. A show cause notice for cancellation (REG-17) must be answered on REG-18 within seven working days from the date of service of the notice under CGST Rule 22(1) — again working days, not calendar days. In every case the clock runs from service or receipt rather than from the day you happened to open the portal. Establish that date before you do anything else, because every other date depends on it.

Silence is treated as having nothing to say, and the officer proceeds on the information already in front of them. On a scrutiny notice that means the discrepancy stands and the matter can move to a demand. On a registration query it means the application can be refused. On a show cause notice for cancellation it means the cancellation can be ordered. In every case a reply that is merely adequate is dramatically better than no reply.

You can ask, in writing, before the stated window closes — an extension requested after the date has passed is a different and much weaker conversation. Ask on the record against the notice rather than informally, state what you are still assembling and why, and keep replying to the substance in the meantime rather than waiting for a decision on the request.

Not always, and the distinction is worth drawing honestly. Where the notice asks for a document or a clarification you actually have, replying yourself is normal and the tool covers it. Where it disputes a legal position, alleges suppression, proposes a penalty, or where the figures need reconstructing across returns, that is professional territory. This tool tells you when your situation does not match one it can state properly, instead of producing a confident letter about facts that are not yours.

No, and this trips people up because something adjacent did change. The 2025 Act renamed income-tax forms and moved the 194-series TDS sections — Form 26AS became Form 168, and the TDS certificate forms were renumbered too. GST is a separate statute and was untouched: the CGST Act, its rules and its forms carry the same numbers they always did. If a page tells you there is a new-Act equivalent of a GST form number, it is wrong.
