ASMT-14 GST Notice Section 63: Unregistered Person Assessment Guide
There is a specific kind of disbelief that comes with an ASMT-14 notice, because of who typically receives it. You either run a business you genuinely did not think needed GST registration, or your registration was cancelled some time ago and you assumed that closed the chapter. Either way, the notice tells you the department disagrees, and they have estimated a tax bill on your behalf.
ASMT-14 is issued under Section 63 of the CGST Act, 2017, and it applies to a narrower, more specific group than most people assume. It is not the notice that follows an ignored GSTR-3A for a registered taxpayer. That path runs through Section 62 and ends in a different form (ASMT-13). ASMT-14 exists for two distinct situations: a person who never obtained GST registration despite being legally liable to, or a person whose registration was cancelled by the department under Section 29(2) but who remained liable to pay tax for the period in question.
If either of those describes your situation, here is exactly what happens next and what you can do about it.
What Section 63 Actually Covers
Section 63 of the CGST Act, 2017 addresses the assessment of unregistered persons, or those whose GST registration has been cancelled but who are still liable to pay taxes. It allows a proper officer to assess tax liability based on best judgment within five years from the due date of the relevant annual return.
The section opens with a non-obstante clause, meaning it overrides Sections 73, 74, and 74A. This is a deliberate legal design: the ordinary demand and recovery provisions assume a registered person with filed (or unfiled) returns on record. Section 63 exists for situations outside that framework entirely, where there is no return trail to scrutinize because no registration ever existed, or because the registration that did exist has been cancelled.
Two specific categories of people fall under Section 63:
Category 1: Never registered despite being liable. If your turnover crossed the registration threshold, or if you supply goods or services that require mandatory registration regardless of turnover (inter-state supply, e-commerce operators, certain reverse charge categories), and you never obtained a GSTIN, you fall here.
Category 2: Registration cancelled under Section 29(2), but tax liability continued. If the department cancelled your registration, for instance due to continued non-filing of returns, but you continued to make taxable supplies after the cancellation date, you are treated as an unregistered person for the purpose of Section 63, even though you once held a GSTIN.
One important clarifying point worth knowing: once a person obtains registration, Section 63 generally ceases to apply to that person going forward for that registered period. The provision exists specifically to address the gap created by the absence of valid registration, not as a general-purpose enforcement tool for registered taxpayers.
The Process: From ASMT-14 to ASMT-15
The procedure is set out in Rule 100(2) of the CGST Rules, 2017, and it has clear, fixed steps.
Step 1: The officer gathers evidence. Before issuing any notice, the proper officer needs some basis to believe tax liability exists. This typically comes from third-party data: bank transaction reports, e-Way bill records, information from a buyer's GSTR filings showing purchases from you, property or business registration records, or information received from another department or agency.
Step 2: Notice in FORM GST ASMT-14, with a summary in FORM GST DRC-01. The notice must state the grounds on which the assessment is proposed to be made, the materials relied upon, and the estimated tax liability. This is not a vague allegation: the law requires the officer to specify the basis for the proposed assessment.
Step 3: You get 15 days to reply. This is your opportunity to respond, present your case, and provide evidence: either that you were not liable to register, that the cancellation of your registration ended your taxable activity, that the estimated liability is incorrect, or that the tax has already been paid through some other channel.
Step 4: A mandatory opportunity of personal hearing. This is a critical safeguard built into Section 63, and it is not optional for the department. Courts have consistently held that a hearing must be offered even when the taxpayer does not explicitly request one. The Madras High Court, in Gabriel India Limited vs State Tax Officer (2023), ruled that the department must mandatorily provide an opportunity for personal hearing even if the taxpayer did not select that option in their portal reply.
Step 5: The order in FORM GST ASMT-15, with a summary in FORM GST DRC-07. After considering your reply (or the absence of one) and conducting the hearing, the officer passes the final assessment order. This order quantifies the tax, interest, and any applicable penalty.
The Five-Year Time Limit
The assessment order under Section 63 must be issued within five years from the due date for furnishing the annual return for the financial year to which the unpaid tax relates. This is a hard outer limit. If the officer issues the ASMT-15 order beyond this period, the order is time-barred and can be challenged on that ground alone.
Because Section 63 often deals with old, undocumented periods, this time limit is genuinely worth checking carefully. Identify which financial year the notice relates to, calculate the due date of that year's annual return, and add five years. If the order falls outside that window, raise it explicitly.
Natural Justice Is Not Optional Here: A Recent Court Ruling
This is one of the most useful protections available to anyone facing an ASMT-14, and a recent decision makes it very concrete.
The Orissa High Court, in Laxmikanta Panigrahi vs Commissioner, CT & GST, Odisha (decided 20 January 2025), held that an assessment order under Section 63 issued against a registered dealer who had already discharged the tax was invalid. The court reinforced that while Section 63 overrides Sections 73 and 74, it still embeds the requirement of an opportunity of hearing, and failure to follow this renders the order vulnerable to challenge for procedural impropriety.
In practical terms, this means two things. First, if you can show that tax for the period in question was already paid, whether under your own registration, under someone else's, or in some other documented form, that is a strong and recognised defence. Second, if the department passes an ASMT-15 order without giving you a genuine opportunity to be heard, the order itself can be challenged regardless of the underlying tax position.
The Supreme Court has also held more broadly that a best judgment assessment is an estimate involving guesswork, but that estimate must relate to some actual evidence or material. It cannot be based on mere suspicion. If the ASMT-14 notice does not specify clear grounds and supporting material for the estimated liability, that absence is itself worth raising in your reply.
How to Respond to an ASMT-14 Notice
Identify which category applies to you. Were you never registered, or was your registration cancelled under Section 29(2)? This affects the substance of your defence.
If you were never registered, determine whether you were actually liable to register. Check your turnover for the relevant period against the applicable threshold (currently Rs 40 lakh for goods in most states, Rs 20 lakh for services, with lower thresholds for special category states). If your turnover was genuinely below the threshold and you did not fall into a mandatory registration category, this is your primary defence, supported by sales records, bank statements, and any other evidence of turnover.
If your registration was cancelled and the dispute is about the period after cancellation, gather evidence on whether you continued taxable activity. If business operations ceased on or before the cancellation date, present that evidence clearly: closure documentation, bank account closure or inactivity, lease termination, or any formal winding-up steps taken.
If you believe the estimated turnover or tax liability is inflated, challenge the basis of the officer's calculation directly. Ask for the specific material relied upon if it is not already detailed in the notice, and present your own records as a counter-estimate.
File your reply within the 15-day window through the GST portal or as directed in the notice, and explicitly request a personal hearing even though the law requires the officer to offer one regardless.
What Happens After ASMT-15
Once the order is passed, the summary in DRC-07 functions as the formal demand. If the amount remains unpaid, the department can initiate recovery proceedings under Section 79, which include bank account attachment, and in cases of immediate revenue risk, even provisional attachment of property under Section 83 can be invoked during the proceedings.
If you disagree with the ASMT-15 order, you can file an appeal before the Appellate Authority under Section 107 of the CGST Act, within three months of the order being communicated, with a possible one-month condonation of delay at the Appellate Authority's discretion.
ASMT-14 vs ASMT-13: Two Different Roads to Best Judgment Assessment
These two forms are often confused because both arise from "best judgment assessment," but they apply to entirely different people.
ASMT-13 is issued under Section 62, and it applies to registered persons who failed to file their returns despite a prior GSTR-3A notice. The taxpayer has a valid GSTIN; the issue is non-filing.
ASMT-14 is issued under Section 63, and it applies to persons without a valid, currently active registration: either they never registered despite being liable, or their registration was cancelled and they continued taxable activity afterward.
If you currently hold an active GST registration and the dispute is about a missed return, the relevant provision is Section 62 and the relevant form is ASMT-13, not ASMT-14.
People Also Ask: ASMT-14 GST Notice
What is an ASMT-14 notice under GST? ASMT-14 is a show cause notice issued under Section 63 of the CGST Act, 2017, read with Rule 100(2) of the CGST Rules. It applies to persons who failed to obtain GST registration despite being liable to, or whose registration was cancelled under Section 29(2) but who remained liable to pay tax. It proposes a best judgment assessment of tax liability.
How many days do I have to reply to an ASMT-14 notice? 15 days from the date of service of the notice. The proper officer must also provide an opportunity of personal hearing before passing the final order, regardless of whether you specifically request one.
What is the difference between ASMT-13 and ASMT-14? ASMT-13 is issued under Section 62 to registered persons who failed to file their returns after receiving a GSTR-3A notice. ASMT-14 is issued under Section 63 to persons without valid active registration, either because they never registered or because their registration was cancelled while tax liability continued.
What is the time limit to pass an order under Section 63? The assessment order in FORM GST ASMT-15 must be issued within five years from the due date for furnishing the annual return for the financial year to which the unpaid tax relates. An order passed beyond this period is time-barred.
Can a Section 63 assessment order be challenged if I was not given a personal hearing? Yes. Courts have repeatedly held that the opportunity of personal hearing under Section 63 is mandatory, not optional, and must be offered by the department even if the taxpayer does not explicitly request it. An order passed without this opportunity is vulnerable to challenge on grounds of procedural impropriety.
Can I get the assessment dropped if I register for GST now? Registering now does not automatically erase liability for the past period under question, but it does end the applicability of Section 63 going forward. For the period already under assessment, your defence needs to address the specific liability the notice raises, supported by evidence of turnover, payment, or cessation of business activity.
Real Questions People Ask When They Receive This Notice
"I run a small business and genuinely believed my turnover was below the GST registration threshold. Now I have an ASMT-14 saying otherwise. What do I do?" Pull together your actual sales records, bank statements, and any invoices for the period in question. Calculate your turnover precisely against the applicable threshold for your state and category of supply. If your turnover was genuinely below the threshold, present this clearly in your reply with supporting documents, and explicitly request the personal hearing to walk the officer through your numbers directly.
"My GST registration was cancelled by the department two years ago for non-filing, but I had actually stopped the business around the same time. Now I have an ASMT-14 for a period after the cancellation date. Is this valid?" This is a common and defensible situation. If you can show that taxable activity ceased on or before the cancellation date, including evidence like bank account inactivity, lease termination, or any other documentation of closure, this is strong evidence against the assumption that liability continued past cancellation. Present this clearly and in detail in your reply.
"The notice estimates a turnover for my business that is far higher than what I actually did. How was this number arrived at?" The notice is required to specify the grounds and material the officer relied upon. If this is not clearly detailed, request it explicitly in your reply. Courts have held that best judgment assessments must be based on actual evidence, not mere suspicion or arbitrary multiplication. Present your own documented turnover figures as a counter to the estimate, supported by bank statements and any third-party records you can access.
"I already paid GST on these transactions through a different mechanism, like reverse charge paid by my buyer, or I supplied through a registered platform that collected tax. Does this matter?" Yes, significantly. If the tax for the relevant transactions has already been discharged, whether by you, by your buyer under reverse charge, or by a platform under applicable e-commerce provisions, this is a recognised and strong defence. The Orissa High Court has specifically held that an assessment order issued where tax had already been discharged is invalid. Present clear documentary proof of this payment in your reply.
"I missed the 15-day window to reply. Has my case already been decided against me?" Not necessarily. The officer is still required to conduct a hearing before passing the order, regardless of whether a written reply was submitted. Contact the jurisdictional officer as soon as possible, request the personal hearing that is your right under the law, and present your case and evidence at that stage. If an ASMT-15 order has already been passed without giving you that opportunity, this is a valid ground to challenge the order in appeal.
