A GST-registered freelancer logs into the GST portal and finds a notice sitting there, ASMT-10, with a list of discrepancies between their GSTR-3B and GSTR-1 filings and a 30-day deadline to respond. The instinct is to panic. The correct response is to read exactly what is being asked, gather the specific records that address it, and reply on time in the right format, since most scrutiny notices are routine mismatches, not accusations of wrongdoing.
Here is what a GST scrutiny notice actually is, why freelancers get them, and the exact steps to reply so it closes cleanly instead of escalating into an audit.
What an ASMT-10 scrutiny notice actually is
An ASMT-10 notice is issued under Section 61 of the CGST Act when a GST officer's system flags a discrepancy while examining your filed returns. It is not a demand for recovery of tax or penalty, and it is not evidence of wrongdoing. It is a request for an explanation of a specific mismatch the system detected, most commonly a gap between Input Tax Credit claimed in GSTR-3B and what your suppliers actually reported, underreported outward tax liability compared to GSTR-1, or a discrepancy between your e-invoices and your filed returns.
For a freelancer, the most common trigger is a mismatch between GST collected on invoices raised and GST actually deposited, often caused by a timing difference (an invoice raised in one month, payment and filing reconciled in another) rather than any real error. The notice lists the specific discrepancy the system found, so read it carefully before assuming the worst; most scrutiny notices resolve with nothing more than a clear written explanation.
You have 30 days to reply, in Form ASMT-11
You have 30 days from the date the notice is issued to respond using Form ASMT-11, filed through the GST portal. In your reply, you either explain the discrepancy with supporting documentation (invoices, bank statements, reconciliation working) if you believe your filing was correct, or you accept the discrepancy and pay the shortfall along with any applicable interest through Form DRC-03. A further extension can be granted at the assessing officer's discretion if you genuinely need more time to gather records, commonly around 15 days in practice though the statute does not fix this as a guaranteed right, so request it well before the original deadline rather than letting it lapse silently.
If the 30-day window expires before you reply, the GST portal typically will not accept a late ASMT-11 submission, and you will need to respond physically at the jurisdictional GST office or by email to the assessing officer instead, which is slower and more likely to draw closer scrutiny. Reply on time even if your explanation is not perfectly polished; a timely, honest response is far better than a late, well-prepared one.
What happens if the officer is not satisfied, or you do not reply
If your explanation is accepted, the officer issues a closure order in Form ASMT-12, and the matter ends there, nothing further happens. If your explanation is not accepted, or you fail to reply within the window, the officer can escalate to a formal audit under Section 65 or a special audit under Section 66, or move to a formal demand notice, either under Section 73 (non-fraud) or Section 74 (fraud or wilful misstatement) for periods up to FY 2023-24, or under the newer consolidated Section 74A for FY 2024-25 onward, which replaced 73 and 74 for later periods from November 1, 2024. Any of these carry a much higher administrative burden and potential penalty than the original scrutiny notice ever did.
This is the real reason to take an ASMT-10 seriously even when the underlying discrepancy is genuinely minor: the notice itself is low-stakes, but ignoring it or replying poorly is what turns a routine mismatch into a formal audit. A clear, well-documented reply within the 30-day window resolves the overwhelming majority of these notices at the ASMT-11 stage.
How to prepare your reply
Start by identifying exactly which return period and which specific figure the notice flags, most freelancer notices point to a specific month's GSTR-3B versus GSTR-1 comparison or an ITC mismatch against your suppliers' GSTR-2A/2B data. Pull the relevant invoices, bank statements showing GST deposits, and a simple month-by-month reconciliation showing how your filed numbers tie back to your actual transactions.
If the discrepancy is a genuine timing difference, an invoice raised in March but the corresponding GST deposited and reported in April, explain this plainly with the specific invoice numbers and dates as evidence, rather than a general statement that "everything is accounted for." If you find the notice is correct and there was a real filing error, pay the shortfall via DRC-03 along with applicable interest promptly; accepting and correcting a genuine error quickly is treated far more favourably than disputing an error that turns out to be real.
How to avoid getting a scrutiny notice in the first place
Reconcile your GSTR-1 and GSTR-3B every month before filing, rather than filing each independently and hoping they match, since the mismatch between these two returns is the single most common trigger for a scrutiny notice. Keep a running record of every invoice raised against every GST payment made, so if a notice does arrive, you already have the documentation ready instead of reconstructing months of records under a 30-day deadline. See the guide on creating a professional GST-ready freelance invoice for what a proper invoice needs to include so your outward liability is captured correctly from the start, and the guide on the GST composition scheme for freelancers if simplifying your filing obligations entirely is worth considering for your situation.
Rinto's GST math is calculated automatically on every invoice, splitting CGST, SGST, or IGST based on your client's state, so the figures on your invoices are consistent by default rather than something you have to manually get right on every single one, which is exactly where small reconciliation errors tend to creep in over a year of manual invoicing.
Frequently Asked Questions
What is a GST ASMT-10 notice and does it mean I am in trouble?
An ASMT-10 notice is issued under Section 61 of the CGST Act when a GST officer's system detects a discrepancy in your filed returns, such as a mismatch between GSTR-3B and GSTR-1 or an Input Tax Credit claim that does not match your suppliers' filings. It is a request for an explanation, not a demand for recovery of tax and not evidence of wrongdoing. Most freelancer scrutiny notices are routine timing mismatches or filing errors that resolve cleanly with a clear, documented reply within the 30-day window.
How long do I have to reply to a GST scrutiny notice?
You have 30 days from the date the ASMT-10 notice is issued to reply using Form ASMT-11 on the GST portal. A further extension can be granted at the officer's discretion, commonly around 15 days in practice, if you genuinely need more time, but request it before the original deadline lapses rather than assuming it is a guaranteed right. If the 30-day window expires without a reply, the portal typically stops accepting a late ASMT-11 submission, and you have to respond physically at the GST office or by email instead, which is slower and more likely to draw further scrutiny.
What happens if I do not respond to a GST scrutiny notice?
If you do not reply within 30 days, or if your explanation is not accepted, the officer can escalate to a formal audit under Section 65 or 66, or move to a formal demand notice, under Section 73 or 74 for periods up to FY 2023-24, or under Section 74A, the consolidated provision that replaced both for FY 2024-25 onward, depending on whether fraud or wilful misstatement is suspected. These carry a significantly higher administrative burden and potential penalty than the original notice. A timely, well-documented reply at the ASMT-11 stage resolves the large majority of scrutiny notices before they ever escalate this far.
What is the most common reason a freelancer gets a GST scrutiny notice?
The most common trigger is a mismatch between GSTR-3B and GSTR-1, often caused by a timing difference where an invoice is raised in one month but the corresponding GST deposit and reporting lands in a different month. Input Tax Credit claims that do not match what your suppliers reported in their own filings is another frequent cause. Reconciling GSTR-1 and GSTR-3B every month before filing, rather than filing each independently, is the single most effective way to prevent this trigger.
Should I hire a CA to reply to a GST scrutiny notice, or can I handle it myself?
A straightforward timing mismatch with clear supporting documentation is often manageable to reply to yourself, provided you understand exactly which figures the notice is flagging and can produce clean records addressing it. For a genuine filing error, a discrepancy you cannot clearly explain, or if the notice hints at a larger issue like fraud or wilful misstatement, involve a CA before replying, since a fraud-linked demand notice carries meaningfully higher penalties than a routine non-fraud matter, whether it falls under Section 73/74 for older periods or Section 74A for FY 2024-25 onward, and is worth avoiding through a properly prepared response the first time.
