Introduction
Goods and Services Tax (GST) was implemented in India in July 2017 with the aim of simplifying the tax system and bringing various indirect taxes under one law. However, over time, it has become evident that the procedural framework of GST is quite complex and confusing.
For businessmen, Chartered Accountants (CAs), tax consultants, and tax advocates, filing GST returns, reconciling data, responding to notices, and understanding the law has become a challenging and time-consuming task.
In this context, Artificial Intelligence (AI) has emerged as a modern and supportive tool that can significantly assist in making current GST practices faster, easier, and more accurate. It can save both time and effort, which can then be utilized in more productive tasks.
This article explains how AI can support your GST practice. We can also explore contents of notices, AI-generated replies, and related case laws in simple language to understand the whole tax law. If we communicate our issue to AI clearly and correctly, it can help us effectively. Additionally, we will see how AI can answer your various queries related to GST law.
It is important to note that while AI can assist you but the final decision must always be made after verifying facts and data. Artificial intelligence cannot replace human intelligence, but it can certainly support human efforts, provide speed and efficiency, and save time in repetitive tasks.
Keep in mind: if AI provides any information on a subject, you must not use it blindly. You should verify the suggested provisions, notifications, circulars, or case laws from your own reliable sources before acting on them. Sometimes, while the core information may be correct, the mentioned section numbers, rules, notifications, circulars, or case laws may be incorrect — and the reasons behind such discrepancies will be explained later in this article.
Before understanding how AI can assist you in GST practice, let’s first explore why GST practice is so complex. This will help us identify the key areas where AI can be of real assistance in some of the complex GST issues.
Let’s look at some of the major complexities in GST practice and how AI can help you tackle them:-
1. GSTR-3B Return Cannot Be Revised
If you make a mistake in the GSTR-3B return, it cannot be revised. Any correction can only be made in the subsequent return period. Even if you rectify the error later, the department may still issue a notice based on the earlier mistake.
This situation arises primarily because the main return under GST (GSTR-3B) does not have a provision for revision, even though the GST law itself does not prohibit revision.
When a notice is received in such cases, it becomes necessary to trace exactly in which subsequent return the correction was made.
If you upload your accounting data and GST return details into an AI system, it can help you not only identify the final corrected figures for replying to the notice, but also generate a suitable draft response.
Let’s now see how AI analyses this issue and how it can help draft a proper reply if such a notice has been received.
| AI:- Under the current GST framework, if a taxpayer makes an error in the GSTR-3B return, there is no option to revise it. Any rectification must be carried out in the subsequent return period. Unfortunately, even if the error is corrected in a later return, the GST department may still issue a notice based on the original mistake.
This issue stems from a structural limitation — GSTR-3B, being the primary return under GST, does not allow revisions, despite there being no legal prohibition under the GST Act against making such corrections. When a notice is received in such circumstances, the taxpayer must pinpoint exactly when and where the correction was made in the subsequent returns. This can often be a time-consuming and error-prone process. This is where Artificial Intelligence (AI) can be a valuable tool. By uploading your accounting data and return filings into an AI system, it can:
Here is a sample reply to a GST notice issued due to a discrepancy in GSTR-3B caused by an earlier mistake that was later corrected in a subsequent return. This reply assumes the taxpayer has rectified the error and has the supporting data. To, Subject: Reply to Notice No. [Insert Notice Number] regarding discrepancy in GSTR-3B Return Respected Sir/Madam, This is with reference to the above-mentioned notice wherein a discrepancy has been pointed out in the GSTR-3B return filed for the month of [Insert Month/Year], particularly in respect of [mention nature of discrepancy, e.g., underreported output liability / excess ITC claimed, etc.]. We would like to respectfully submit the following: 1. Nature of the Error: The said discrepancy occurred due to an inadvertent clerical error while filing GSTR-3B for the period [Insert Month/Year]. This was not a case of tax evasion or suppression of facts. 2. Subsequent Rectification: The error was identified during internal reconciliation, and the necessary correction was made in the GSTR-3B of the subsequent tax period i.e., [Insert Month/Year]. A summary of the correction is provided below:
3. Enclosed herewith are copies of both the original and rectified GSTR-3B returns for your reference. 4. Legal Position: As per the GST law, there is no restriction on correcting errors in subsequent periods. Although GSTR-3B is non-revisable, the law permits such rectification under Section 39(9) of the CGST Act, 2017. 5. No Loss to Revenue: 6. Request for Consideration: In light of the above facts, we kindly request you to treat the matter as satisfactorily explained and drop the proceedings initiated through the above notice. We remain fully compliant and are committed to timely and accurate filing of returns. We request your kind consideration in this matter. Thanking you, Enclosures: 1. GSTR-3B for [Original Month] 2. GSTR-3B for [Correction Month] 3. Reconciliation Statement |
2. MISMATCH BETWEEN VENDOR AND PURCHASER RETURNS
If a supplier fails to report an invoice in their GSTR-1, it will not reflect in your GSTR-2B, and consequently, you will not be able to claim Input Tax Credit (ITC) — even if you possess the correct invoice and have duly paid the tax.
This is a common issue, and many taxpayers receive notices from the department in this regard.
If you receive such a notice, you are required to submit a proper reply defending your position. AI can help prepare an appropriate response, provided you give it the correct inputs and documents.
Even if your objective is to explain your position or to seek additional time from the department, AI can help generate a suitable draft.
Now let’s see how AI analyzes this issue and prepares a reply to such a mismatch notice from the GST department.
| AI:- Here is a sample reply to a GST notice regarding mismatch between the supplier’s GSTR-1 and the recipient’s GSTR-3B/2B — leading to denial of ITC:
To, Subject: Reply to Notice No. [Insert Notice Number] regarding mismatch in ITC – Supplier Invoice not reflected in GSTR-2B Respected Sir/Madam, With reference to the above-mentioned notice regarding denial of Input Tax Credit (ITC) on certain invoices not reflecting in GSTR-2B, we respectfully submit the following: 1. Factual Background: The said ITC pertains to inward supplies received from our registered supplier(s), and valid tax invoices were duly received and recorded in our books of accounts. We had made payment to the vendor along with GST and claimed ITC in good faith. 2. Reason for Mismatch: The mismatch has occurred due to non-reporting of the said invoice(s) by the supplier in their GSTR-1, resulting in non-appearance in our GSTR-2B. 3. Supporting Documents Enclosed: We are enclosing the following to substantiate our claim:
4. Legal Position:
5. Request for Time / Supplier Rectification: We have already contacted the supplier and requested them to rectify the omission in their next GSTR-1. We request your kind indulgence and a reasonable opportunity to get the same rectified to avoid unjust denial of ITC. 6. Conclusion: In view of the above, we humbly request you to consider our explanation and drop the proposed ITC disallowance. We remain committed to full compliance and transparency. Thanking you, Enclosures: 1. Copy of Invoice(s) 2. Bank Payment Proof 3. Supplier Ledger 4. Email/Letter Communication with Supplier |
3. ITC REVERSAL DUE TO NON-PAYMENT WITHIN 180 DAYS
| As per GST rules, if payment against an invoice is not made within 180 days, the corresponding Input Tax Credit (ITC) must be reversed. The credit can be reclaimed once the payment is actually made.
However, during departmental surveys and audits, if this situation is discovered, a notice is often issued, even if the payment has already been made later. A specific scenario arises when you’ve made the payment after 180 days but receive the notice afterward — in such a case, reversal becomes irrelevant as the condition has already been fulfilled, and re-availing of ITC is possible. Also, in cases where your ITC balance remains consistently in surplus, there is no loss to the exchequer, which strengthens your argument. If you provide these facts to AI — including invoice dates, payment dates, and credit utilization history — it can generate a comprehensive reply to such a notice and explain the situation convincingly. Let’s now see how AI understood this issue and generated a suitable reply to a notice under this scenario. Here is a sample reply to a GST notice regarding non-reversal of ITC due to non-payment within 180 days: To, Subject: Reply to Notice No. [Insert Notice Number] – Regarding ITC Reversal under Rule 37 for Non-Payment within 180 Days Respected Sir/Madam, With reference to the above-mentioned notice alleging non-reversal of Input Tax Credit (ITC) under Rule 37 of the CGST Rules due to non-payment to the supplier within 180 days, we wish to respectfully submit the following: 1. Background of the Transaction The transaction in question pertains to inward supplies for which valid tax invoices were received and ITC was availed accordingly. Due to unforeseen commercial constraints, payment against the invoice was made after 180 days from the date of invoice. 2. Compliance Already Fulfilled At the time of receipt of this notice, the payment to the supplier has already been made in full. Therefore, the condition under Section 16(2) read with Rule 37 has been satisfied. In such a scenario, reversal of ITC and re-availment becomes a procedural formality with no impact on the revenue. 3. ITC Utilization Status It is further submitted that our ITC balance has consistently remained in surplus, and no undue benefit has been claimed. The department has not suffered any revenue loss in this regard. 4. Judicial and Administrative View Several advance rulings and departmental instructions recognize that where payment is made and credit has not been unduly utilized or encashed, strict penal action may not be warranted, and procedural irregularities can be condoned. 5. Our Request In view of the above facts and circumstances, we request you to kindly consider our bona fide compliance, acknowledge that payment has been made, and treat the notice as resolved. We assure you of our commitment to full compliance and cooperation with departmental requirements. Thanking you, Enclosures: 1. Copy of Tax Invoice 2. Payment Proof (Bank Statement / UTR) 3. Ledger of Supplier 4. ITC Ledger Summary (Optional, if showing surplus balance) |
4. FILING ANNUAL GST RETURNS IS HIGHLY COMPLEX
The process of preparing GSTR-9 (Annual Return) and GSTR-9C (Reconciliation Statement) is extremely complex due to the extensive data reconciliation and detailed disclosures required. The chances of errors are high, especially when dealing with large volumes of transactions across the year.
In such cases, AI can play a significant role in simplifying the process. By feeding your financial data and return filings into an AI system, it can:

5. ITC AVAILED ON PURCHASES FROM A SUPPLIER WHOSE REGISTRATION WAS CANCELLED RETROSPECTIVELY
If you have purchased goods and availed Input Tax Credit (ITC), but your supplier’s GST registration was cancelled retrospectively, the department may issue you a notice to reverse the ITC on the grounds that the supplier was not a valid registered person on the date of the transaction.
| Such notices are common and can be quite challenging, especially when the purchase was genuine, tax was paid, and the invoice was valid at the time of transaction.
In these situations, AI can help you draft a proper and legally sound reply, supported by relevant case laws and legal principles. If you provide the following information to AI:
AI can generate a detailed reply referencing judicial rulings that state bona fide purchasers should not be penalized for supplier-side compliance failures, especially when there is no fault, fraud, or collusion. Let’s now look at how AI understands this issue and prepares a proper response based on legal precedents. Here is a sample reply to a GST notice regarding Input Tax Credit (ITC) availed on purchases from a supplier whose registration was cancelled retrospectively: To, Subject: Reply to Notice No. [Insert Notice Number] – Regarding ITC availed on supplies from supplier whose registration was cancelled retrospectively Respected Sir/Madam, With reference to the above-mentioned notice, we respectfully submit the following in relation to the Input Tax Credit (ITC) claimed by us on purchases made from a registered supplier whose registration has subsequently been cancelled with retrospective effect. 1. Background of the Transaction We had made genuine purchases from M/s [Supplier Name] bearing GSTIN [Supplier GSTIN] during the period [Insert Period]. The tax invoices were valid, GSTIN was active on the date of transaction, and tax was paid to the supplier through banking channels. The ITC was claimed in good faith based on available documentation. 2. Retrospective Cancellation Not Known to Us At the time of the transaction, there was no public or official communication regarding the supplier’s registration status, and the cancellation was done later with retrospective effect, which was completely beyond our knowledge and control. 3. Legal Position We respectfully rely on the following judicial precedents:
These judgments reinforce that a genuine and tax-paid transaction cannot be denied credit merely due to retrospective action against the supplier, unless there is fraud or connivance. 4. Request for Consideration In view of the facts, legal position, and supporting documents, we kindly request you to:
We remain fully compliant and are committed to cooperating with the department in all aspects. Thanking you, Enclosures: 1. Copy of Tax Invoices 2. Bank Payment Proof 3. Supplier Ledger 4. GSTR-2A showing reflection at the time of transaction (if applicable) |
Let’s look at another situation:
An ex-employee, out of malice, has filed an RTI application with the GST Department and submitted a letter alleging that you have committed tax evasion under GST.
In response, the department asked you whether such information related to your business should be shared with the said individual. You clearly responded that no information related to your business should be provided to any external person.
Despite this, the department immediately issued a notice to you, asking for purchase and sale bills, account books, and related records for the past five years. The notice mentions that the department is in possession of “certain information” indicating tax evasion on your part.
In this context, you now need to respond with an objection letter questioning both the necessity and validity of such a notice — assuming that the so-called “information” is based solely on the ex-employee’s RTI application and letter.
Let’s now see how AI formulates a suitable and reasoned objection letter in response to such a notice.
| To, The Proper Officer [Jurisdictional GST Office Name] [Office Address]Subject: Objection to Notice Issued Based on Malicious RTI Complaint by Ex-Employee GSTIN: [Your GSTIN] Name of Business: [Your Business Name]Respected Sir/Madam,This is with reference to the notice dated [Insert Notice Date], received from your office, wherein we have been asked to produce purchase/sale invoices, account books, and related documents for the last five financial years. The notice mentions that the department has received “information” alleging tax evasion on our part.I respectfully submit the following objections and facts for your consideration:1. Source of Allegation – RTI Application by Ex-EmployeeWe have strong reasons to believe that the “information” referred to in the notice is derived from an RTI application and a letter submitted by our former employee, who holds no present association with our business and is acting out of personal grudge.It is also pertinent to mention that we had earlier responded to the department’s query on this RTI matter, clearly objecting to the sharing of our business information with any external party. 2. Departmental Action Based Solely on Malicious Complaint Issuing a notice solely on the basis of an unverified and malicious complaint, without any preliminary verification or independent evidence, raises concerns over procedural fairness and misuse of authority. The law does not allow harassment of taxpayers based on baseless accusations by disgruntled individuals. 3. Legal and Procedural Safeguards Ignored It is respectfully submitted that before initiating such a wide-reaching demand (covering 5 years of records), the department must first:
4. Our Request In light of the above, we respectfully request that:
We are responsible taxpayers and remain committed to full compliance with all legal obligations. However, we also expect that departmental actions will be based on genuine, verified inputs and not mere hearsay. Thanking you, |
LET US HAVE A LOOK AT HOW AI EXPLAIN THE CERTAIN PROVISIONS OF THE GST LAW
1. I purchased a car that I use in my business and claimed Input Tax Credit (ITC) on it. However, the department has issued a notice stating that I am not eligible to claim this ITC. Please explain the reason behind this.
Let’s see how AI responds to this issue:
| AI’s Response:
Under the CGST Act, 2017, Section 17(5) specifically lists the blocked credits, i.e., cases where Input Tax Credit (ITC) is not allowed, even if the goods or services are used in the course or furtherance of business. One such blocked credit is: Section 17(5)(a): ITC is not available in respect of motor vehicles for transportation of persons having approved seating capacity of not more than 13 persons (including the driver), except when such motor vehicles are used for:
Since you have purchased a car (a motor vehicle for transportation of persons) and unless you are in the business of selling cars, providing transport services, or running a driving school, you are not eligible to claim ITC on that car — even if it is used for business purposes. Conclusion: The department’s notice is legally valid if your case does not fall under the exceptions provided in Section 17(5). You may not be entitled to ITC on the car purchase, and the department may rightly seek reversal of the credit. |
2. I reported an invoice related to April 2024 in my GSTR-1 in August 2024. The department is now demanding interest for the period from April 2024 to August 2024. I also reported this sale in my GSTR-3B in August 2024 itself, and my input credit was always higher than the output tax of this invoice.” Analyse this problem and reply the notice.

MOST IMPORTANT QUESTION
Sometimes AI provides incorrect case law references, incorrect sections, circulars, or notifications. Why does this happen, and how can one avoid it or protect against its consequences?
| AI:- Your question is extremely important from the perspective of practical caution in using AI. It is absolutely true that sometimes AI may refer to the wrong case law, notification, or legal section, and there are specific reasons behind this:
Reasons Why AI Might Give Incorrect Legal References: 1. Training Data Limitations: AI is trained on a wide range of data, but it may not have real-time access to all official or up-to-date legal databases unless specifically integrated. Without the latest official updates, it may generate outdated or inaccurate references. 2. Pattern-Based Prediction: AI generates text based on patterns and probabilities. If a question involves multiple legal domains or overlapping sections, AI might mistakenly select the closest “pattern match” instead of the precise citation. 3. Overconfidence in Language: AI may present incorrect information confidently. This is a limitation known as “hallucination,” where the AI fabricates references that look plausible but are incorrect or non-existent. 4. Ambiguous or Incomplete Queries: If the question asked is not clear or lacks context, AI might assume the wrong scenario and pull irrelevant legal references. How to Avoid or Mitigate These Issues: 1. Cross-Verification with Official Sources: Always verify any legal reference, section, or case law from official government websites (like CBIC, GST Portal, or judicial portals) before relying on it in legal matters or compliance. 2. Use Reliable AI Tools with Source Integration: Use AI platforms (like this one) that are linked to authentic GST Acts, Rules, Circulars, and ICAI material. Ask for citations or extracts directly when in doubt. 3. Avoid Blind Trust – Be a Validator: Treat AI suggestions as initial guidance or a draft, not a final authority. Especially for filing, notices, appeals, or representations, a human expert should always review. 4. Ask for Source and Section Citation Clearly: Prompt AI to provide exact section numbers, circular numbers, or notification dates so you can cross-check them. Conclusion: AI is a powerful assistant but not a substitute for legal judgment. For high-stakes or compliance-sensitive matters, always validate AI-generated outputs with actual laws and official circulars. This practice will protect you from errors and legal risks. |
AI HALLUCINATION
Now the Last question :- What is HALLUCINATION in AI? Is it the reason behind wrong answers, incorrect case law, or notifications, etc.?
AI:- The term “hallucination” in AI refers to a situation where the AI generates confident-sounding but factually incorrect or fabricated responses. This can include:
Why does hallucination occur?
Is hallucination the main reason for incorrect legal answers? Yes, hallucination is one of the key reasons for wrong or misleading information given by AI, especially in legal or technical fields. Therefore, always validate AI responses through reliable sources before relying on them for compliance or decision-making. |
