MSME 15-Day Payment Rule: A Corporate Guide to Section 43B(h)

Key Takeaways

• Shift to Payment-Based Deductions: The most significant change is the introduction of Section 43B(h) to the Income Tax Act, 1961. This section mandates that expenses for purchases from Micro and Small Enterprises (MSEs) are deductible only in the financial year they are actually paid, not when the liability is incurred.
• Strict Payment Timelines: Businesses must adhere to the payment timelines prescribed in the MSMED Act, 2006: 15 days if no written agreement exists, and a maximum of 45 days if there is a written agreement. Failure to meet these deadlines results in the disallowance of the expense for that year.
• Increased Compliance Burden: Companies are now required to identify and verify the MSME status of their suppliers (via Udyam Registration Certificate), update their accounting and ERP systems to track payment deadlines, and face increased scrutiny during audits.
• No "Direct Tax Code 2025" Yet: It is crucial to understand that as of today, the Income Tax Act, 1961, remains the governing law. The "Direct Tax Code 2025" is a proposed simplification and is not yet in effect. The current MSME payment rule operates under the existing 1961 Act.

PART 1: EXECUTIVE SUMMARY

(Word Count: 198)

This guide provides a detailed analysis of the new compliance landscape concerning payments to Micro, Small, and Medium Enterprises (MSMEs), a change often mistakenly associated with a new "Direct Tax Code 2025." The critical amendment is the insertion of Section 43B(h) into the existing Income Tax Act, 1961, effective from the Assessment Year 2024-25.

• The Old Law (1961): Previously, under the accrual system of accounting, businesses could claim a deduction for an expense when the invoice was booked, regardless of when the payment was made to the MSME supplier. While the MSMED Act, 2006, prescribed payment timelines, non-compliance primarily led to interest penalties rather than a direct disallowance of the principal expense amount in the year of accrual.

• The New Law (Amendment to the 1961 Act): Section 43B(h) fundamentally alters this by linking the deductibility of the expense to the actual payment date. If a payment to a registered Micro or Small Enterprise is not made within the timeline specified in the MSMED Act (15 days for no agreement, 45 days with an agreement), the expenditure is disallowed for that financial year. The deduction can only be claimed in the financial year the payment is eventually made.

• Who is Impacted: This change impacts all entities—companies, LLPs, partnership firms, and individuals—who purchase goods or services from registered Micro and Small Enterprises and follow the mercantile (accrual) system of accounting. It does not apply to payments made to Medium enterprises.

PART 2: DETAILED TAX ANALYSIS

1. Background & Corporate Impact

The introduction of Section 43B(h) via the Finance Act, 2023, is a deliberate policy measure by the government to address the persistent issue of delayed payments to the MSME sector, which is a critical component of the Indian economy. Delayed payments severely hamper the working capital and liquidity of these smaller enterprises, inhibiting their growth and sustainability.

The corporate impact of this provision is substantial and multifaceted:

• Direct Impact on Taxable Income: The primary consequence of non-compliance is a direct increase in the buyer's taxable income for the financial year. If payments amounting to ₹1 Crore are delayed beyond the statutory due dates as of March 31st, this entire amount is added back to the company's profit, leading to a significant and avoidable tax outgo.
• Cash Flow Management: The rule forces a systemic shift in the payable management processes of corporations. Companies that previously relied on extended credit terms from smaller vendors now face a direct financial disincentive. This necessitates a re-evaluation of budgeting, cash flow forecasting, and vendor payment cycles to align with the 15/45 day timelines.
• Vendor Relationship Dynamics: While intended to protect MSMEs, the rule has had mixed practical effects. Some large corporations have reportedly started reducing their business with MSMEs or are de-registering their own MSME status to avoid the stringent compliance requirements. This requires careful management of vendor relationships and clear communication regarding payment terms and compliance expectations.
• Interest Disallowance: It is critical to note that any interest paid for delayed payments to MSMEs, as mandated under the MSMED Act, is not an allowable expense for tax purposes. This further adds to the financial burden of non-compliance.

2. 1961 Act vs. The "Direct Tax Code 2025" (Conceptual)

There is significant confusion in the public domain regarding a "Direct Tax Code 2025." It is imperative to clarify that the Income Tax Act, 1961, is the law currently in force. The Direct Tax Code (DTC) is a proposal aimed at simplifying and modernizing India's direct tax system, but it has not been enacted.

The new MSME payment rule is an amendment within the existing 1961 Act, not a feature of a new Code.

3. Audit & ERP Reporting Requirements

The enforcement of Section 43B(h) has significantly increased the compliance and reporting burden, with a direct impact on statutory audits and internal systems.

• Auditor Verification: During the statutory audit, auditors are now mandated to meticulously verify compliance with Section 43B(h). This includes:

  • Identification of MSME Suppliers: Auditors will require management to provide a complete list of suppliers registered as Micro or Small Enterprises. This is typically verified by obtaining Udyam Registration Certificates from all vendors.
  • Ageing Analysis of Payables: A detailed ageing report of MSME creditors as of the balance sheet date is a primary audit document. The auditor will scrutinize this to identify all invoices outstanding for more than the 15/45 day limit.
  • Testing of Payment Terms: Auditors will test whether written agreements exist and whether the payment terms stipulated within them are in line with the 45-day maximum prescribed by the MSMED Act.
  • Disallowance Calculation: The audit team will independently calculate the amount to be disallowed and ensure it is correctly added back in the computation of taxable income in the tax audit report (Form 3CD).

• ERP System Enhancements: To manage this compliance effectively, businesses must upgrade their Enterprise Resource Planning (ERP) systems:

  • Vendor Master Updates: The vendor master file must be updated with a specific field to flag suppliers as "Micro," "Small," "Medium," or "Unregistered." This classification is the bedrock of the entire compliance process.
  • Automated Due Date Calculation: ERP systems should be configured to automatically calculate the payment due date for MSME vendors based on the invoice date and the presence (45 days) or absence (15 days) of a written agreement.
  • Pre-Payment Controls & Alerts: The system should generate alerts for upcoming MSME payment deadlines. Ideally, payment processing systems should be configured to prioritize these payments to avoid inadvertent delays.
  • Customized Reporting: ERPs need to be able to generate on-demand reports that list all outstanding MSME payables, their due dates, and the number of days overdue. This is essential for both internal reviews and providing audit evidence.

• MCA Reporting: Beyond the Income Tax Act, companies are also required to file a half-yearly return, MSME Form 1, with the Registrar of Companies (RoC) detailing any payments to MSMEs that are outstanding for more than 45 days.

4. Financial Controller's Action Plan 2026

To navigate this new regulatory environment, Financial Controllers and CFOs must implement a robust action plan for the fiscal year 2025-26 and beyond.

1. Immediate Vendor Re-Classification (Q1 2026):

   • Launch a comprehensive exercise to contact all suppliers and request their Udyam Registration Certificate.
   • Update the ERP vendor master file to accurately reflect the MSME status (Micro/Small) of each vendor. This cannot be a one-time exercise; it must be integrated into the new vendor onboarding process.

2. Process & Systems Overhaul (Q1-Q2 2026):

   • Review and amend all existing procurement contracts to ensure payment terms with MSMEs do not exceed 45 days.
   • Collaborate with the IT department to implement the necessary ERP system changes for automated tracking and reporting of MSME payables.
   • Redesign the invoice processing and payment workflow to fast-track MSME invoices.

3. Internal Controls & Training (Q2 2026):

   • Conduct training sessions for procurement, accounts payable, and legal teams to ensure they understand the implications of Section 43B(h).
   • Establish a monthly review mechanism where the accounts payable team presents a report on MSME payment status to the Financial Controller to identify and resolve potential delays proactively.

4. Financial Reporting & Audit Preparedness (Q3-Q4 2026):

   • Ensure that the provision for tax is correctly calculated at the end of each quarter, factoring in any potential disallowances under Section 43B(h).
   • Prepare and maintain a comprehensive file with all MSME certificates, agreements, and payment evidence to facilitate a smooth statutory and tax audit.

5. Strategic Review (Ongoing):

   • Analyze the impact of the rule on the company's working capital cycle.
   • Assess the risk of certain critical suppliers de-registering from MSME status and develop contingency plans.

5. Final Advisory

The introduction of Section 43B(h) is not merely a procedural change; it is a fundamental shift that weaponizes tax law to enforce commercial payment discipline. The "cost" of delaying payments to MSMEs has moved beyond interest penalties to a direct and substantial impact on a company's profit after tax. The financial and operational risks associated with non-compliance are now too significant to ignore.

Our team advises all businesses to treat compliance with this provision as a high-priority matter. Proactive measures, including robust system implementation, process re-engineering, and stringent internal controls, are not just recommended—they are essential for sound corporate governance and prudent tax management in the current regulatory environment. Ignoring these requirements will inevitably lead to increased tax liabilities, potential litigation, and scrutiny from regulatory authorities.
