Rule 37 is an important provision under the Goods and Services Tax (GST) framework in India. It deals with Input Tax Credit (ITC) under GST, a mechanism that allows businesses to offset the GST they pay on inputs against the GST they collect on outputs. This blog explores the specific provisions of Rule 37 and its impact on businesses. We will be discovering how this rule shapes the accounting and financial strategies of companies, ensuring that they effectively manage their tax liabilities. 

Exploring Rule 37: Input Tax Credit (ITC) under GST

Input Tax Credit (ITC) under GST ensures that taxes paid on inputs and services are available as credit to businesses, thereby eliminating cascading taxation. Under Rule 37, this mechanism becomes particularly critical in maintaining the integrity of the GST system. It outlines specific conditions under which Input Tax Credit can be claimed, ensuring that only eligible credits are utilized. This is important for preventing misuse of the ITC system and safeguarding the government’s revenue interests.

Furthermore, Rule 37 plays a significant role in promoting CGST and SGST compliance among businesses. By setting clear guidelines for the availing of ITC, it encourages businesses to maintain accurate and transparent records of their transactions. This not only aids in efficient tax administration but also helps businesses in streamlining their accounting processes. In essence, Rule 37 acts as a balancing tool in the GST framework, ensuring that while businesses benefit from the ITC, they also adhere to the principles of fiscal responsibility and transparency.


Compliance Procedures and Requirements

Complying with Rule 37 is crucial for businesses to avoid penalties and ensure smooth operations. To adhere to this rule, businesses must be vigilant and proactive in their approach. This involves not only understanding the rule thoroughly but also implementing systems and processes that facilitate compliance.

Compliance procedures include:

  • Timely Payments: Businesses must prioritize the timely payment of their supplier invoices. According to Rule 37 eligibility criteria, if payment to a supplier is not made within 180 days from the date of the invoice, the Input Tax Credit claimed on that purchase must be reversed. This condition is set to encourage prompt financial transactions and maintain a healthy cash flow in the economy. To avoid the reversal of ITC, businesses should implement efficient accounts payable systems and regularly monitor their payment schedules.
  • Record-keeping: Proper documentation and record-keeping are essential to demonstrate compliance with Rule 37. This involves systematically organizing all GST ITC documentation requirements such as purchase invoices, contracts, payment receipts, and correspondence with suppliers. These records serve as a proof of transactions and are helpful during audits and inspections. Effective record-keeping not only ensures compliance but also aids in internal financial management, allowing for better tracking of expenses and tax liabilities.
  • Filing Accurate Returns: The accurate filing of GSTR-3B returns is essential for reporting ITC and its reversals. Businesses must ensure that the details of input tax credits availed and reversed are accurately reflected in these returns. This requires a thorough reconciliation of purchase records with the GST returns filed by suppliers. Errors or discrepancies in return filings can lead to legal complications and financial penalties. Therefore, regular internal reviews and audits of GST returns are recommended to maintain accuracy and CGST and SGST compliance.

Impact of Rule 37 on Businesses

Recognizing the impact of Rule 37 is important for companies looking to optimize their tax benefits while adhering to the legal framework. Here are some of the significant implications  that Rule 37 has for businesses:

  • Financial Burden: Under Rule 37, not paying suppliers within 180 days leads to ITC reversal with interest, increasing financial strain. Businesses must be timely in their payments to avoid these extra costs.
  • Cash Flow Management: This rule emphasizes the need for efficient cash flow management. Timely payments are a must to prevent ITC reversals, necessitating a balance between revenue inflow and supplier payments.
  • Documentation: Maintaining detailed transaction records is essential. Proper GST ITC documentation requirements support CGST and SGST compliance and help in tracking financial activities, ensuring that businesses can readily demonstrate adherence to Rule 37 during audits.

Recent Amendments and Updates to Rule 37

GST rules are subject to amendments and updates. Stay informed about changes to Rule 37 to remain compliant with the latest regulations. The most recent update, Notification No. 19/2022-CT (R), has clarified the method of ITC reversal. Here are the recent amendments to Rule 37:

  • Proportionate Reversal of ITC (Notification No. 19/2022-CT(R)): This amendment clarified that the ITC reversal under Rule 37(1) needs to be done only in proportion to the unpaid invoice amount and the corresponding tax payable. Previously, there was confusion about whether the entire ITC had to be reversed. This change was implemented on October 1st, 2022.
  • Introduction of Rule 37A: This new rule, introduced through Notification No. 26/2022- Central Tax dated December 26, 2022, deals with ITC reversal in cases where the supplier fails to deposit the tax paid by the recipient in their GSTR-3B. Under Rule 37A, the recipient must reverse the claimed ITC on such invoices if the supplier hasn’t deposited the tax by September 30th of the following financial year. This reversal needs to be reflected in the recipient’s GSTR-3B for the period ending November 30th of the same financial year. However, the recipient can reclaim the reversed ITC once the supplier pays the due taxes.
  • GSTN Advisory No. 613: This advisory, issued on November 14, 2023, provides further clarification on the application of Rule 37A. It emphasizes that the reversal requirement applies only to invoices reflected in the supplier’s GSTR-1 but not filed in their GSTR-3B by the specified deadline.
  • Additional Update: There is some ambiguity regarding the interest rate applicable to reversed ITC under Rule 37. While the latest amendment only refers to section 50 of the CGST Act, 2017, it’s unclear whether interest will be charged at 18% (per section 50(1)) or 24% (per section 50(3)).

Practical Examples and Case Studies

To understand Rule 37 better, let’s explore some practical examples and case studies:

Example 1: Manufacturing Company Fails to Pay Supplier

Scenario: A manufacturing company claims Input Tax Credit (ITC) on raw materials but does not pay the supplier within 180 days.

Rule 37 Application: According to Rule 37 of the GST laws, if the recipient does not pay the supplier the value of the supply along with the tax thereon within 180 days of the invoice date, the Input Tax Credit availed by the recipient will be added back to his output tax liability, along with interest.


Let’s assume the value of raw materials is INR 100,000.

  • GST Rate: 18% (assumed for this example).
  • ITC Claimed: 18% of 100,000 = INR 18,000.

If the payment is not made within 180 days:

  • ITC to be reversed = INR 18,000.
  • Interest (assuming 18% per annum for simplicity): Interest for 6 months on INR 18,000.

Example 2: Supplier Doesn’t Deposit Tax

Scenario: A supplier does not deposit the tax collected from a buyer.

Rule 37 Application: Rule 37 mainly deals with the reversal of ITC in the hands of the buyer if the supplier does not receive payment. However, the non-deposit of tax by the supplier can lead to implications under other GST provisions, potentially impacting the buyer’s ITC if the supplier’s GST compliance is not in order.


Let’s assume the sale value is INR 150,000.

  • GST Rate: 18% (assumed for this example).
  • Tax collected from the buyer = 18% of 150,000 = INR 27,000.

If the supplier fails to deposit the tax:

  • The action will be taken against the supplier as per GST laws.
  • The buyer’s ITC could be at risk if the supplier’s compliance affects their GST return.

Here’s a summary of the scenarios and implications for each example under Rule 37 of the GST laws:

Example Scenario Assumed Value (INR) GST Rate Implication
1. ITC Reversal (Non-payment) Manufacturing company fails to pay the supplier within 180 days after claiming ITC. 100,000 18% ITC of INR 18,000 (18% of 100,000) to be reversed, plus interest for 6 months.
2. Non-deposit of Tax by Supplier Supplier does not deposit the tax collected from the buyer. 150,000 18% Tax of INR 27,000 (18% of 150,000) not deposited by the supplier; buyer’s ITC at risk.

In Conclusion

Rule 37 is a crucial component for complying with CGST and SGST guidelines, ensuring businesses adhere to the necessary tax regulations. It’s important for businesses to understand its provisions, follow compliance procedures diligently, and stay updated with the latest amendments. Failure to do so can result in the reversal of ITC along with an increased tax liability. Given the complexity of GST regulations, seeking guidance from a qualified tax professional is advisable.
