Are Medium Enterprises Excluded from MSME Timely Payment Rules in 2026?

Key Takeaways

• Exclusion of Medium Enterprises: The stringent timely payment regulations, which disallow expenses for delayed payments, currently apply only to Micro and Small Enterprises. Medium Enterprises are explicitly excluded from this rule's purview.
• Continuation of Existing Law: It is anticipated that the principles of Section 43B(h) of the Income Tax Act, 1961, will be foundational to any forthcoming Direct Tax Code (DTC). This suggests the distinction between Micro/Small and Medium enterprises will likely persist.
• Tax Disallowance Risk: For payments to Micro and Small Enterprises, failure to adhere to the statutory 15/45 day payment timeline results in the disallowance of the expenditure in that financial year. The deduction is only permitted in the year the payment is actually made.
• Udyam Registration is Key: The applicability of these timely payment rules hinges on the supplier's status as a registered Micro or Small Enterprise under the MSMED Act, holding a valid Udyam Registration Certificate.

PART 1: EXECUTIVE SUMMARY

This compliance guide addresses the critical question of whether Medium Enterprises fall under the mandatory timely payment rules, which carry significant tax consequences, within the framework of the anticipated Direct Tax Code (DTC) 2025. Our analysis is grounded in the most recent and impactful legislative changes to understand the trajectory of tax policy moving into the tax year 2026.

• The Old Law (Income Tax Act, 1961): Historically, while the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006, stipulated payment timelines, there was no direct, punitive income tax consequence for delays. The primary recourse for a delayed MSME was interest claims and dispute resolution.
• The New Law (Finance Act, 2023 Amendment): A significant change was introduced via Section 43B(h) to the Income Tax Act, 1961, effective from Assessment Year 2024-25. This provision disallows the deduction of an expense for payments made to Micro and Small Enterprises if the payment is not made within the timelines prescribed by the MSMED Act. This effectively shifts the deduction from an accrual to a payment basis for delayed payments.
• Who is Impacted: The rule directly impacts all businesses procuring goods or services from registered Micro and Small Enterprises. Critically, the legislation specifically targets only "Micro" and "Small" enterprises for this tax-related compliance. Medium Enterprises are not covered by the provisions of Section 43B(h). Therefore, while timely payments to medium enterprises are advisable for good financial practice, there is no corresponding tax disallowance for delays under this specific provision.

PART 2: DETAILED TAX ANALYSIS

1. Background & Corporate Impact

The introduction of Section 43B(h) into the Income Tax Act, 1961, represents a strategic move by the government to enforce payment discipline and improve the liquidity and financial health of the most vulnerable segments of the MSME sector. By linking payment timelines directly to tax deductibility, the provision creates a compelling financial incentive for buyers to pay their Micro and Small suppliers on time.

For corporations, this has necessitated a complete overhaul of vendor management and payment processing systems. The primary impact is the potential for a significant increase in taxable income if dues to Micro and Small suppliers are not cleared within the statutory deadlines by the financial year-end. The "timely mailing as timely filing/paying" concept, often found in other jurisdictions, is not the operative standard here; Indian law focuses on the actual date of payment for compliance with this section.

2. 1961 Act vs 2025 Direct Tax Code

While a finalized Direct Tax Code 2025 is not yet in effect, professional analysis assumes that popular and recently enacted provisions that align with core policy objectives will be retained. Section 43B(h) is a prime example of such a provision. It directly addresses the critical issue of working capital for the smallest businesses. Therefore, it is our professional opinion that any new Direct Tax Code will carry forward the principle of disallowing expenses for delayed payments to MSMEs.

The critical distinction lies in the MSME classification itself. The law, as it stands, is precise in its application.

This deliberate exclusion of Medium Enterprises from the ambit of Section 43B(h) is a key policy distinction. The focus of this punitive tax measure is clearly on protecting the most financially sensitive businesses. As such, for the tax year 2026, whether under the existing Act or a new DTC, corporations will face a tax disallowance only for delayed payments to vendors who are verifiably registered as Micro or Small enterprises.

Statutory Payment Timelines (under MSMED Act, 2006):

• With Written Agreement: Payment must be made on or before the date agreed upon, which cannot exceed 45 days from the day of acceptance of goods/services.
• Without Written Agreement: Payment must be made within 15 days from the day of acceptance.

3. Audit & ERP Reporting Requirements

Compliance with Section 43B(h) mandates robust internal controls and system configurations.

• Vendor Master Data: The first and most critical step is to correctly identify and classify all suppliers. This involves:
  • Collecting Udyam Registration Certificates from every supplier.
  • Updating the vendor master file in the ERP system to flag suppliers as "Micro," "Small," "Medium," or "Unregistered."
  • Periodically verifying the registration status, as a supplier's classification can change.
• ERP System Configuration:
  • Payment terms in the ERP must be configured to align with the 15/45 day rule for Micro and Small suppliers.
  • The system should be able to generate reports on outstanding dues to MSMEs, highlighting any amounts that are overdue or approaching their due dates.
• Audit Trail: During a statutory or tax audit, auditors will require a clear trail to verify compliance. This includes:
  • A ledger of MSME creditors.
  • Proof of payment dates for all invoices from Micro and Small suppliers.
  • Copies of written agreements where a 45-day credit period is utilized.
  • A reconciliation statement for the financial year detailing any amounts disallowed under Section 43B(h) and added back to taxable income.

4. Financial Controller's Action Plan 2026

To ensure compliance for the financial year 2025-26 and avoid any adverse tax consequences, Financial Controllers must implement a clear action plan:

• Q1-Q2 2025: Vendor Re-evaluation & System Setup
  • Launch a campaign to collect Udyam certificates from all existing vendors.
  • Mandate the submission of Udyam certificates as part of the new vendor onboarding process.
  • Work with the IT department to configure the ERP system to track MSME status and payment deadlines accurately.
• Q3 2025: Process Review & Training
  • Train the accounts payable team on the new rules, emphasizing the critical distinction between Micro/Small and Medium enterprises.
  • Review and renegotiate payment terms with Micro and Small suppliers to ensure they are documented in writing and do not exceed 45 days.
• Q4 2025 & Jan-Mar 2026: Proactive Monitoring
  • Begin running weekly or bi-weekly ageing reports specifically for Micro and Small enterprise creditors.
  • Prioritize payments to these vendors to ensure they are cleared before the 15/45 day deadline.
  • Before the fiscal year-end on March 31, 2026, conduct a final review of all outstanding payables. Any amount due to a Micro or Small enterprise that is outstanding beyond its statutory due date must be identified for disallowance.

5. Final Advisory

The legislative framework under Section 43B(h) is unambiguous: its stringent tax disallowance provisions do not apply to dues payable to Medium Enterprises. The compliance burden and financial risk for corporations are squarely focused on ensuring timely payments to registered Micro and Small Enterprises. While the Direct Tax Code 2025 aims to simplify tax law, this targeted provision, designed to protect the smallest businesses, is expected to be a continuing feature of India's tax landscape. Corporate finance and compliance teams must institutionalize processes to identify, track, and prioritize payments to Micro and Small suppliers to mitigate tax risks effectively. The SEO keyword "timely mailing as timely filing/paying rule" is not the guiding principle; adherence to the actual payment deadlines specified in the MSMED Act is paramount.
