Mastering the 45-Day MSME Payment Rule: A 2025-26 Compliance Guide

Key Takeaways

• Shift to Payment-Based Deduction: Under the new compliance framework effective from A.Y. 2024-25, tax deductions on purchases from Micro and Small Enterprises (MSEs) are no longer based on the accrual system. They are now strictly allowed only in the year the payment is actually made, if not paid within the statutory deadlines.
• Strict 15/45 Day Payment Deadlines: Businesses must pay MSE suppliers within 45 days if a written agreement exists, or within 15 days if there is no agreement. Failure to meet these deadlines results in the disallowance of the expense for that financial year, increasing taxable income.
• Proviso to Section 43B Not Applicable: Unlike other dues covered under Section 43B, payments to MSEs that are delayed beyond the statutory deadline cannot be claimed as a deduction even if they are paid before the tax return filing date. The deduction is deferred to the financial year in which the payment is actually made.
• Critical Role of ERP Systems: Systems like TallyPrime are essential for compliance. They enable businesses to identify MSE suppliers, track payment due dates bill-by-bill, and generate reports to monitor compliance, thereby preventing accidental disallowances.

PART 1: EXECUTIVE SUMMARY

(This guide addresses the significant compliance changes introduced by Finance Act, 2023, referred to herein as the new compliance framework for 2025 and beyond.)

• The Old Law (Income-tax Act, 1961): Previously, under the accrual system of accounting, businesses could claim a tax deduction for expenses incurred in a financial year, regardless of when the payment was made. While Section 43B governed certain payment-based deductions, there was no specific, stringent provision linking the deductibility of all supplier payments to strict, short-term payment deadlines.

• The New Law (Framework under Section 43B(h) from 2025): The Finance Act, 2023, introduced a pivotal change by inserting clause (h) into Section 43B of the Income-tax Act, 1961. Effective from the Assessment Year 2024-25, this clause mandates that any sum payable to a Micro or Small Enterprise is deductible only on a payment basis if not paid within the time limit prescribed in Section 15 of the MSMED Act, 2006. This timeline is 45 days from the date of acceptance of goods/services if a written agreement is in place, and 15 days in all other cases. If a payment due on March 31st is not made within this timeframe, the deduction is lost for that year and can only be claimed in the year the payment is eventually made.

• Who is Impacted: This change universally impacts all entities—corporations, firms, and individuals—who are liable for tax audits and make purchases from suppliers registered as Micro or Small Enterprises under the MSMED Act. It necessitates a complete overhaul of procurement-to-payment cycles and places significant pressure on finance and accounts payable departments to ensure timely vendor payments to avoid adverse tax consequences.

PART 2: DETAILED TAX ANALYSIS

1. Background & Corporate Impact

The introduction of Section 43B(h) is a strategic move by the government to address the persistent issue of delayed payments to the MSME sector, which is critical to the national economy. For decades, Micro and Small Enterprises have faced significant working capital constraints due to elongated payment cycles from their larger corporate buyers. This new provision uses the Income Tax Act as a tool to enforce financial discipline.

The Corporate Impact is multifaceted and severe:

• Increased Tax Liability: The most direct impact is the potential for a higher tax bill. An expense disallowed under Section 43B(h) is added back to the company's taxable income for the year. For a company in the 30% tax bracket, a disallowed expense of ₹1 Crore translates to an immediate tax outflow of ₹30 Lakhs.
• Cash Flow Management Pressure: The law forces a realignment of cash flow priorities. Financial controllers can no longer use payables to Micro and Small suppliers as a float. Payments must be meticulously planned and executed within the 15/45 day window, which can strain liquidity if not managed proactively.
• Supply Chain Disruption: Strained relationships with MSME suppliers due to payment delays can lead to disruptions. Furthermore, financially stressed suppliers may be forced to increase prices or become unreliable, impacting the buyer's procurement costs and operational stability.
• Intensified Compliance Burden: Companies must now implement robust systems to identify, track, and report payments to MSE suppliers. This involves significant administrative effort, from vendor master data management to enhanced reporting for audits.

3. Audit & ERP Reporting Requirements

The new provision significantly enhances the responsibilities of both the company and its auditors. Enterprise Resource Planning (ERP) systems like TallyPrime are no longer just accounting software; they are now indispensable compliance tools.

Key Requirements:

1. Vendor Identification: The first step for any business is to identify which of its suppliers are registered as Micro or Small Enterprises. This requires collecting Udyam Registration Certificates from all vendors and updating the vendor master file.
2. ERP Configuration (TallyPrime): TallyPrime has specific features to manage this compliance:
   • Updating Party Ledgers: Users can update the supplier's ledger to specify their MSME status (Micro, Small, or Medium) and enter their Udyam Registration Number.
   • Setting Credit Periods: TallyPrime allows setting the applicable credit period (15 or 45 days) for each MSME supplier, which the system then uses to track the due date for each invoice.
   • Customized Reporting: The software can generate reports that specifically filter outstanding payables to MSME vendors, show the number of overdue days, and identify bills at risk of disallowance. This allows for prioritized payment processing before the financial year-end.
3. Tax Audit Reporting (Form 3CD): The tax audit report has been amended to include specific reporting requirements for Section 43B(h). Auditors are now required to report the amount of expenditure disallowed due to delayed payments to MSEs. This necessitates that companies provide accurate and verifiable data to their auditors from their accounting systems.
4. Financial Statement Disclosures: Under the Companies Act, 2013, and MSMED Act, companies must disclose details of outstanding dues to MSE suppliers in the notes to their financial statements. This includes the principal and interest amount outstanding.

4. Financial Controller's Action Plan 2026

To navigate this new landscape, Financial Controllers and CFOs must adopt a structured and proactive approach.

Phase 1: Identification and System Setup (Immediate Action)

• Vendor Communication: Immediately circulate a formal request to all suppliers to provide their Udyam Registration Certificate.
• Vendor Master Cleanup: Create a dedicated team to update the vendor master file in your ERP (e.g., TallyPrime). Tag each vendor as 'Micro', 'Small', 'Medium', or 'Non-MSME'. Remember, the rule only applies to Micro and Small enterprises.
• ERP Configuration: Configure TallyPrime or your existing ERP to capture MSME status and automatically calculate due dates based on invoice dates and the 15/45 day rule.

Phase 2: Process Re-engineering (Q1-Q2 2026)

• Review Procurement Contracts: Scrutinize all existing and new vendor agreements. Ensure payment terms are clearly defined and do not exceed 45 days for MSE suppliers.
• Invoice Processing Workflow: Streamline the invoice-to-pay process. Implement a system to fast-track invoices from MSE suppliers to ensure they are approved and processed well within the deadline.
• Payment Run Prioritization: Modify your payment cycles. Instead of a standard monthly or bi-monthly payment run, implement a system that prioritizes payments based on their statutory due date under Section 43B(h).

Phase 3: Monitoring and Reporting (Ongoing)

• Generate Weekly Reports: Use TallyPrime to generate weekly ageing reports specifically for Micro and Small enterprise payables. The report should clearly highlight invoices approaching their due date.
• Pre-emptive Alerts: Set up alerts for the accounts payable team for any MSE invoice that is within 7-10 days of its payment deadline.
• Conduct Internal Audits: Periodically audit the process to ensure compliance and identify any gaps before they lead to disallowances.

5. Final Advisory

The transition to this new compliance framework under Section 43B(h) is not merely a procedural update; it is a fundamental shift in how businesses must manage their payables. Procrastination or mismanagement will directly translate into higher tax liabilities and potential regulatory scrutiny. Our team advises all businesses to treat this as a high-priority compliance mandate. Leveraging technology like TallyPrime is essential for accurate tracking and reporting. The cost of non-compliance, both in terms of disallowed expenses and the mandatory non-deductible interest on delayed payments, is far too significant to ignore. Businesses must act now to align their systems and processes with this new reality.
