    Understand the Top 5 GST Notices and How to Reply them Professionally with My Startup Solution

    It's ‌​‍​‌‍​‍‌​‍​‌tough enough to manage a startup without having to worry about a GST notice. At My Startup Solution, we know that a tax department message can be quite scary and thus we provide the services of guiding the businesses through these top 5 GST notices in a confident manner. However, it is known that a GST notice does not always indicate the worst situation. Being familiar with the different types of notices and having a proper response ready can get you out of them without a ​‍​‌‍​‍‌​‍​‌‍​‍‌hitch.

    Why GST Notices Matter?

    Notices​‍​‌‍​‍‌​‍​‌‍​‍‌ from local tax officials are quite frequent under the India Goods and Services Tax (GST) system. Such communications, which can be as simple reminder letters or as serious show-cause notices, are the means through which the GST authorities point out discrepancies, demand tax or take help in clarifying the facts. It is very important that you as a business owner (a startup in particular) make the right and timely response. Not handling the dispatch can result in the imposition of additional assessments, penalization or even a legal case against ​‍​‌‍​‍‌​‍​‌‍​‍‌you.

    1. GSTR-3A Notice – Default for Non-Filing

    One of the most frequent GST notices is the GSTR-3A notice. This is a default notice sent to taxpayers who have not filed mandatory returns like GSTR-1, GSTR-3B, GSTR-4, or GSTR-8.

    How to respond professionally:

    • In​‍​‌‍​‍‌​‍​‌‍​‍‌ case of any pending returns, promptly file them together with any applicable late fees and interest.
    • Briefly ‌​‍​‌‍​‍‌​‍​‌‍​‍‌indicate that the return has been filed or if there is a problem, describe it.
    • Reply through the GST portal, mentioning the notice and attaching the copies of your filings as a proof.

    Consequences​‍​‌‍​‍‌​‍​‌‍​‍‌ of not responding: In case no reply is sent within 15 days, the officials can determine the tax based on the information available to them and impose a fine of Rs 10,000 or 10% of the tax due, whichever is ​‍​‌‍​‍‌​‍​‌‍​‍‌higher.

    2. CMP-05 Notice – Composition Scheme Eligibility

    If you are on the Composition Scheme, you might receive a CMP-05 show-cause notice. This challenges your eligibility for the simplified composition regime.

    How to respond professionally:

    • Provide a clear justification for why you qualify for the composition scheme like turnover and nature of business).
    • Attach supporting documents like turnover statements, financials or other proofs.
    • Submit your reply within the time limit (usually 15 days).

    Consequences​‍​‌‍​‍‌​‍​‌‍​‍‌ of not responding: If there is no response, a penalty under Section 122 may be imposed and the composition benefit may be lost by an order in CMP-07.

    3. REG-03 / REG-17 / REG-23 – Registration-Related Notices

    These​‍​‌‍​‍‌​‍​‌‍​‍‌ notices relate to GST registration:

    • REG-03 is a communication in which the concerned authority seeks clarification of details or requests additional ​‍​‌‍​‍‌​‍​‌‍​‍‌documents.
    • REG-17 is a notice indicating a cause showing request for explanation why the cancellation of your GST registration should not be made.
    • REG-23 is a letter asking for an explanation as to why the abolition of a previously registered revocation should be rescinded.

    How to respond professionally:

    • For REG-03: Send back a letter in REG-04. In your response, clearly explain each issue raised in the notice and attach the requested documents.
    • For REG-17:  Write a well-argued statement in REG-18 to counter the allegations made in the notice, citing continuation of business, showing of operations and adherence to rules.
    • For REG-23: Employ REG-24 to specify the reasons for which the termination of registration was not justified, submit trade documents, invoices and location ​‍​‌‍​‍‌​‍​‌‍​‍‌proof.

    Consequences of not responding: Your application may be rejected (REG-05), or your registration may be cancelled (REG-19).

    4. Scrutiny Notice (ASMT-10) / Assessment Notice

    A scrutiny notice (Form ASMT-10) is the information given to you when the GST department after performing risk-based checks on your returns, identifies discrepancies in the returns filed by you.

    How to respond professionally:

    • First of all, go through the notice in detail and check whether the details mentioned in it are accurate or not.
    • In case you acknowledge the difference, simply make the payment of the additional tax along with interest (if any) in advance.
    • Draft an explanation in ASMT-11, where you clarify the differences, provide the supply invoices and mention any corrections made.
    • Upload your records and the payment voucher on the GST portal.

    Consequences​‍​‌‍​‍‌​‍​‌‍​‍‌ of not responding: In case the response is completely ignored or if clarity is not provided within 30 days or the given time, the result will be the officer deciding to take further action: a local audit under Section 65, a special audit under section 66 or recovery ​‍​‌‍​‍‌​‍​‌‍​‍‌​‍​‌‍​‍‌​‍​‌‍​‍‌proceedings.

    5. Demand Notice (DRC-01) / Show Cause Notice for Demand

    One of the most serious GST notices is the DRC-01 show-cause notice, demanding unpaid or short-paid tax, interest or penalty.

    How​‍​‌‍​‍‌​‍​‌‍​‍‌ to respond professionally:

    • In​‍​‌‍​‍‌​‍​‌‍​‍‌ case of consenting to the demand, the payment is to be made via DRC-03.
    • If the demand is rejected, a detailed response may be submitted in DRC-06.
    • Provide real explanations together with the corresponding invoices, credit notes or reconciliations.
    • Writing should always be of a formal and polite tone and you should back up your statements with obvious ​‍​‌‍​‍‌​‍​‌‍​‍‌proof.

    Consequences​‍​‌‍​‍‌​‍​‌‍​‍‌ of not responding: Normally, a period of 60 days is granted to respond. In the event that the officials are made to wait, they might opt to raise the fines or even, in a few instances, open a prosecution ​‍​‌‍​‍‌​‍​‌‍​‍‌file.

    Consequences of Ignoring GST Notices

    Ignoring GST notices can be risky. Here is what could happen:

    • Assessment without your input: Authorities may assess tax on a “best judgment” basis.
    • Heavy penalties: Depending on the type of notice, penalty rates can be steep (10%, 25%, or more).
    • Audit / special audit: Non-response to scrutiny can lead to an audit under Sections 65 or 66.
    • Recovery actions: Non-payment after demand may lead to recovery steps like bank attachment and property seizure.
    • Cancellation of GST registration: Failing to answer registration-related notices may cancel your GST registration.
    • Legal or prosecution risk: ​‍​‌‍​‍‌​‍​‌‍​‍In case of fraud or willful evasion, especially under Section 74, we could be prosecuted and help regarding GST notice.
