MSME 45 Days Payment Rule Explained: Applicability, Benefits & Penalties

Quick Overview

• The MSME 45 days payment rule requires buyers to clear dues to eligible MSMEs within the prescribed timeline to claim income tax deductions under Section 43B(h).
• Payments must generally be made within 15 days if there is no written agreement and within 45 days if a written agreement exists.
• If payment is delayed beyond the applicable period, the expense can be claimed as a tax deduction only in the year in which the payment is actually made.
• The rule applies primarily to buyers dealing with Micro and Small Enterprises registered under the MSMED Act, subject to eligibility conditions.
• MSME Section 43B became effective from 1 April 2024 (Assessment Year 2025–26 onwards).
• The provision aims to improve cash flow for MSMEs, reduce payment delays, and promote healthier business practices.

The MSME 45-day payment rule introduced through Section 43B(h) of the Income Tax Act encourages timely payments to Micro and Small Enterprises. Businesses purchasing goods or services from eligible MSMEs must make payments within the prescribed period to claim tax deductions in the same financial year. Delayed payments may result in deferred tax deductions, affecting taxable income and cash flow. While the rule strengthens financial stability for MSMEs, businesses need better payment planning and vendor management to remain compliant.

What Is the New MSME 45 Days Payment Rule?

The MSME payment rule introduced through Section 43B(h) links tax deductions with timely payments made to eligible MSMEs.

Earlier, businesses could claim expenses as deductions even if vendor payments remained unpaid for long periods, provided they followed the mercantile accounting system. With the introduction of Section 43B(h), this has changed for payments made to eligible Micro and Small Enterprises.

If payment is not made within the prescribed timeline, the expense cannot be claimed as a deduction during that financial year. Instead, the deduction becomes available only in the year when the payment is actually made. This provision complements the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006, which already mandates timely payments to MSMEs.

Section 43B(h) At a Glance

Why Was the MSME 45 Days Payment Rule Introduced?

Delayed payments have long been one of the biggest challenges faced by MSMEs. Small businesses often depend on regular cash flow to manage salaries, purchase raw materials, pay suppliers, and maintain operations.

When large buyers delay payments for several months, MSMEs experience working capital shortages, making it difficult for them to grow or even sustain their operations. The government introduced the MSME 45-day payment rule to:

• Improve liquidity for Micro and Small Enterprises.
• Reduce outstanding receivables.
• Encourage prompt payment practices among buyers.
• Strengthen the MSME ecosystem.
• Improve business discipline and financial transparency.

By linking tax deductions with payment timelines, businesses now have a stronger incentive to settle dues on time.

Payment Time Limits Under Section 43B(h) for MSMEs

The payment timeline depends on whether a written agreement exists between the buyer and the MSME supplier.

It is important to note that even if both parties agree to a payment period longer than 45 days, the MSMED Act limits the maximum permissible credit period to 45 days. Therefore, agreements extending beyond 45 days will not override the provisions of the Act.

Applicability of Section 43B(h)

Understanding the MSME 45 days payment rule applicability is essential for businesses. Section 43B(h) applies when all of the following conditions are satisfied:

• The supplier is registered as a Micro or Small Enterprise under the MSMED Act.
• Goods or services are supplied by the eligible MSME.
• The buyer follows the mercantile system of accounting.
• Payment remains outstanding beyond the prescribed timeline.

However, the provision does not generally apply to:

• Medium Enterprises.
• Suppliers not registered under the MSMED Act.
• Payments made within the prescribed timeline.
• Certain transactions outside the scope of business expenditure.

Businesses should verify the MSME registration status of vendors before applying the provisions.

Effective Date of Section 43B(h) for MSME Payments

MSME Section 43B became effective from 1 April 2024. This means it applies from:

• Financial Year: 2024–25
• Assessment Year: 2025–26

Businesses filing income tax returns for FY 2024–25 onwards need to consider this provision while calculating allowable business expenses. Proper accounting records and vendor classification have therefore become more important than ever.

How Is the 45-Day Deadline Calculated?

The payment deadline starts from the date of acceptance or deemed acceptance of goods or services under the MSMED Act. Here's how it works:

• Goods or services are delivered.
• Buyer accepts them.
• The payment countdown begins from the acceptance date.
• If the buyer raises a valid objection in writing within the prescribed period, the countdown starts from the date when the objection is resolved.

For example:

• Invoice Date: 5 June
• Goods Accepted: 7 June
• Written Agreement Exists: Yes

The payment should be made on or before 22 July (45 days from acceptance). If payment is made after this date, Section 43B(h) may defer the tax deduction until actual payment.

Example of Section 43B(h) Deduction Applicability

Consider the following example:

ABC Pvt. Ltd. purchases machinery components worth ₹10,00,000 from an eligible Micro Enterprise on 10 January 2025.

• Goods accepted: 12 January 2025
• Written agreement: Yes
• Payment due: 26 February 2025 (45 days)

Scenario 1: Payment made on 20 February 2025

Since payment is made within the prescribed period, ABC Pvt. Ltd. can claim the ₹10,00,000 expense as a deduction while computing taxable income for FY 2024–25.

Scenario 2: Payment made on 15 June 2025

Since payment is delayed beyond the permitted period, the deduction cannot be claimed in FY 2024–25. Instead, it becomes allowable only in FY 2025–26 when the payment is actually made.

This can increase taxable profits for FY 2024–25 and result in a higher tax liability.

Penalties for Delayed Payments to MSMEs

While Section 43B(h) itself does not impose a direct monetary penalty, delayed payments can have significant financial consequences. These include:

• Loss of tax deduction during the current financial year.
• Higher taxable income.
• Increased tax outflow.
• Cash flow pressure due to higher tax liability.
• Possible interest liability under the MSMED Act for delayed payments.

Under the MSMED Act, buyers may also be liable to pay compound interest on delayed payments, making payment delays even more expensive.

Implications of Section 43B(h) on Capital Expenditure

Section 43B(h) mainly affects revenue expenditure that is otherwise deductible while computing business income. Capital expenditure is generally not claimed as a business expense immediately. Instead, businesses claim depreciation over time. Therefore:

• Capital asset purchases are generally not directly impacted by Section 43B(h) in terms of expense deduction.
• However, businesses should still ensure timely payments to eligible MSMEs to avoid disputes, maintain supplier relationships, and comply with MSMED Act provisions.
• Accounting teams should carefully distinguish between capital and revenue expenditure while applying MSME Section 43B.

Benefits of the 45 Days Payment Rule for MSMEs

The MSME payment rule offers several advantages for India's small business ecosystem.

Challenges Businesses Face with the 45 Days Payment Rule

Although beneficial for MSMEs, businesses may encounter certain implementation challenges.

Vendor identification

Companies must accurately identify which suppliers qualify as eligible MSMEs.

ERP and accounting changes

Existing accounting systems may require updates to track payment deadlines automatically.

Cash flow planning

Businesses with long working capital cycles may need to improve liquidity management.

Contract management

Companies should review supplier agreements to ensure payment terms align with statutory limits.

Compliance monitoring

Finance teams must regularly monitor outstanding dues to avoid tax disallowances.

Conclusion
