MSME Payment Compliance: A Guide to Section 43B(h) for Tally & Zoho Users

Key Takeaways

• Shift from Accrual to Payment-Based Deductions: Under the newly inserted Section 43B(h) of the Income Tax Act, 1961, tax deductions for payments to Micro and Small Enterprises (MSEs) are now permitted only in the year the payment is actually made, not when the liability is accrued, if payment timelines are breached.
• Strict Payment Deadlines are Mandated: Businesses must pay Micro and Small Enterprise suppliers within 15 days of acceptance of goods/services if no written agreement exists, or within a maximum of 45 days if there is a written agreement. Failure to do so results in the disallowance of the expense for that financial year.
• ERP & Software Automation is Essential: Existing accounting systems like Tally and Zoho must be reconfigured to identify MSE suppliers, track the 15/45 day payment deadlines for each invoice, and provide real-time reports on pending dues to avoid unintentional non-compliance and tax additions.
• No "New" Direct Tax Code Yet: The compliance changes discussed stem from the Finance Act 2023, which amended the existing Income Tax Act, 1961. While a new Direct Tax Code has been proposed to simplify laws, the current, pressing compliance requirement is Section 43B(h) of the 1961 Act, effective from Assessment Year 2024-25.

PART 1: EXECUTIVE SUMMARY

This compliance guide addresses a significant amendment to India's direct tax laws that fundamentally alters how businesses can claim deductions for payments made to a substantial portion of their supply chain. The core of this change is not a transition to a new Direct Tax Code in 2025, but rather the introduction of Section 43B(h) into the existing Income Tax Act, 1961, effective April 1, 2024. This provision is designed to enforce timely payments to Micro and Small Enterprises (MSEs) and carries substantial tax implications for non-compliance.

• The Old Law (Income Tax Act, 1961 - Pre-Amendment): Previously, under the accrual system of accounting, businesses could claim an expense for goods or services purchased from any supplier in the financial year the invoice was booked, regardless of when the payment was actually made. The general provisions of Section 43B applied to certain statutory payments, but not specifically to trade payables with such stringent timelines.

• The New Law (Section 43B(h) Amendment): The new law mandates that if a buyer fails to pay a registered Micro or Small Enterprise supplier within the timeframe prescribed under the Micro, Small and Medium Enterprise Development (MSMED) Act, 2006, the expense will be disallowed for that financial year. The deduction can only be claimed in the financial year that the payment is actually made. The prescribed timelines are 15 days from the date of acceptance if there is no written agreement, or a maximum of 45 days if a formal written agreement on payment terms exists.

• Who is Impacted: This change affects every business entity that is subject to audit under the Income Tax Act and procures goods or services from suppliers registered as Micro or Small Enterprises under the MSMED Act. This includes large corporations, mid-sized firms, and any other business that has MSEs in its supply chain. The responsibility for compliance and verification of supplier status rests squarely on the buyer.

PART 2: DETAILED TAX ANALYSIS

1. Background & Corporate Impact

The insertion of Section 43B(h) by the Finance Act, 2023, is a targeted legislative measure to resolve the persistent issue of delayed payments crippling the MSME sector, which is a critical component of the Indian economy. By linking tax deductibility directly to payment timelines, the government has created a powerful incentive for buyers to honour their payment obligations promptly.

The corporate impact is immediate and significant:

• Increased Taxable Income: Any payment to an MSE outstanding beyond the statutory 15/45 day limit as of March 31st of the financial year will be added back to the company's taxable income. This can lead to a substantial, and often unplanned, increase in tax liability.
• Working Capital & Cash Flow Pressure: The Accounts Payable (AP) function must be transformed from a cost center focused on payment cycles to a strategic compliance unit. Companies can no longer use extended credit terms with MSE suppliers to manage working capital without facing direct tax consequences. This necessitates a complete re-evaluation of cash flow forecasting and treasury management.
• Supplier Relationship Management: The onus is now on the buyer to identify which of their suppliers are classified as Micro or Small. This requires a formal process of collecting Udyam registration certificates from all vendors and validating them, adding an administrative layer to the procurement and vendor onboarding process.

2. 1961 Act vs. 2025 Direct Tax Code

While the prompt mentions a transition to a Direct Tax Code (DTC) in 2025, the immediate and actionable legal change is Section 43B(h) of the current Income Tax Act, 1961. The proposed DTC aims for broader simplification of the entire tax law. However, Section 43B(h) is a specific, enforced amendment with immediate effect.

3. Audit & ERP Reporting Requirements

The introduction of Section 43B(h) places a significant burden on both statutory auditors and internal financial systems. Auditors are now required to specifically verify compliance with these provisions, which will be a key part of the Tax Audit Report.

Enterprise Resource Planning (ERP) and Accounting Software Requirements:

Manual tracking of these deadlines across thousands of invoices is not feasible. Automation is the only viable path to compliance. Your accounting software must be configured to handle these new requirements.

• Vendor Master Updates:

  • A mandatory field must be created in the vendor master file to tag suppliers as "Micro," "Small," "Medium," or "Other/Not Applicable."
  • The Udyam Registration Number must be stored, and a process for periodic re-verification should be established.

• Invoice Processing Automation:

  • The system should automatically calculate the due date (15 or 45 days) upon invoice entry based on the vendor's MSE status and the presence of a written agreement.
  • Automated alerts should be sent to the AP and finance teams when an invoice for an MSE vendor is approaching its compliance deadline.

• Payment Systems (Tally vs. Zoho):

  • TallyPrime: Tally has introduced features to manage Section 43B(h) compliance. Users can update the MSME status in party ledgers and generate reports that filter outstanding payables to MSE suppliers. Its ageing analysis can be used to prioritize these payments. However, automation of alerts and payment runs may require careful configuration.
  • Zoho Books: As a cloud-native platform, Zoho Books can offer more seamless automation. Its strengths lie in creating automated workflows, real-time dashboards, and integrations with banking systems. It can be configured to automatically identify MSE invoices and prioritize them in payment runs. Its user-friendly interface may also make it easier for non-accounting staff in procurement to track compliance.

4. Financial Controller's Action Plan 2026

To ensure seamless compliance and avoid significant tax liabilities for the Financial Year 2025-26, the office of the Financial Controller must execute a structured action plan.

• Phase 1 (Immediately): Vendor Classification & Communication

  • Initiate a formal communication campaign to all existing suppliers requesting their Udyam Registration Certificate.
  • Create a dedicated team to validate each certificate on the official Udyam portal.
  • Update the vendor master data in your ERP system with the correct MSE status for every single supplier.

• Phase 2 (By Q1 2026): Process & System Re-Engineering

  • Contract Review: Legal and procurement teams must review all standard purchase orders and supplier contracts to ensure payment terms are explicitly stated and do not exceed 45 days for MSEs.
  • ERP Configuration: Work with IT and your ERP implementation partner (Tally/Zoho/other) to configure the system for automated tracking and reporting as outlined in the previous section.
  • AP Workflow Redesign: The AP process must be redesigned to prioritize MSE invoices. The "First-In, First-Out" method is no longer sufficient. Payments must be processed based on the statutory compliance deadline.

• Phase 3 (By Q2 2026): Training & Monitoring

  • Conduct mandatory training sessions for all staff in the procurement, accounts payable, and finance departments.
  • Develop and circulate a clear Standard Operating Procedure (SOP) for vendor onboarding, invoice processing, and payment runs under the new law.
  • Implement a monthly MIS (Management Information System) report that tracks potential 43B(h) disallowances, allowing for corrective action well before the end of the financial year.

5. Final Advisory

The enactment of Section 43B(h) is not merely an accounting update; it represents a fundamental shift in corporate financial discipline. The risk of having legitimate business expenditures disallowed due to procedural payment delays is a significant financial threat. Proactive and automated compliance is no longer optional. Our team advises a cross-functional approach, integrating the tax compliance function deeply with procurement and treasury operations. The cost of configuring ERP systems and tightening payment processes is minimal compared to the potential increase in tax liability and the associated interest penalties under the MSMED Act. This is a board-level compliance issue that demands immediate and sustained attention.
