Section 43B(h) MSME Payment Terms: Audit Checklist & Rules

To protect small businesses from cash flow crunches caused by delayed payments, the Government introduced Section 43B(h) of the Income Tax Act through the Finance Act, 2023. This provision has significantly altered the payment management practices of businesses across India.

Under this rule, any payment due to registered Micro or Small Enterprises that remains outstanding beyond the statutory limits of the MSMED Act will be disallowed as a tax deduction. This means the unpaid amount is added back to the buyer's taxable income for the year, resulting in an immediate income tax liability. This guide provides the complete legal framework, audit checklists, and step-by-step compliance actions.

1. Legal Timelines: Section 15 of MSMED Act, 2006

Section 43B(h) references the payment timelines established in Section 15 of the MSMED Act, 2006. The payment deadlines are split into two categories:

• In the absence of a written agreement: The payment must be completed within 15 days from the date of acceptance of the goods or services.
• If there is a written agreement: The payment must be made within the period agreed upon in writing between the buyer and the seller. However, this agreed period cannot exceed 45 days. Any agreement specifying a longer payment term (e.g. 60 or 90 days) is legally invalid under the MSMED Act, and the maximum limit is capped at 45 days.

2. Micro, Small, and Medium Enterprise Classification

Section 43B(h) applies only to transactions with vendors classified as Micro or Small. The classifications are defined as follows:

Important: Traders (wholesalers and retailers) registered under MSME are eligible only for Priority Sector Lending benefits. They are excluded from the payment protection benefits of Section 15 of the MSMED Act. Therefore, Section 43B(h) disallowances do not apply to outstanding payments due to MSME traders.

3. Tax Audit Checklist for Section 43B(h)

During year-end tax audits, Chartered Accountants will perform the following checks to identify disallowance liabilities:

1. Identify Registered MSME Vendors: Obtain a list of all active suppliers and request copies of their Udyam Registration Certificates. Check their classification status (Micro, Small, or Medium) and confirm they are not registered as traders.
2. Extract Year-End Creditors List: Pull the ledger balances of all sundry creditors outstanding as of March 31st.
3. Verify Aging of Outstanding Invoices: For each outstanding creditor balance on March 31st, compute the days elapsed from the invoice date or date of service acceptance.
4. Review Written Agreements: Inspect purchase orders or contracts to check if a specific payment term (up to 45 days) is defined. If no agreement exists, apply the 15-day limit.
5. Flag Disallowed Creditors: Any invoice outstanding on March 31st that has crossed the 15-day or 45-day limit must be flagged as a disallowance in the Tax Audit Report (Form 3CD).

4. Consequences of Non-Compliance

Failing to pay Micro or Small suppliers within the statutory limits carries two primary financial consequences:

• Tax Addition to Income: Unpaid amounts are added to your net taxable business income. For a corporation in the 30% tax bracket with Rs 10,000,000 of outstanding MSME payables, this triggers an immediate income tax liability of Rs 3,000,000 for that fiscal year.
• Mandatory Interest Penalties: Under Section 16 of the MSMED Act, the buyer is liable to pay compound interest with monthly rests to the supplier on the delayed amount. The interest rate is fixed at three times the bank rate notified by the RBI (which typically totals 18% to 22% p.a.). This interest expense is disallowed as a business expense under Section 23 of the MSMED Act and cannot be used to reduce taxable income.

5. Practical Compliance Workflow for Accounts Teams

To manage MSME compliance effectively and avoid tax additions:

• Collect Udyam Details: Make it a mandatory step during new vendor onboarding to collect Udyam registration certificates and record the classification status in your ERP or accounting software.
• Configure MSME Ledger Groups: In TallyPrime, create a distinct ledger group for registered MSME creditors to isolate their aging details from general trade payables.
• Set Up Ageing Alerts: Run weekly aging reports in Tally to flag invoices approaching their 15-day or 45-day payment deadlines, prioritizing these payouts.

6. Treatment of Year-End Provisions and Accruals

A common point of confusion is the treatment of year-end provisions (such as outstanding audit fees or professional fees accrued on March 31st). If these provisions are due to registered MSME professionals, they must be settled within the statutory timelines:

• Ensure that provision bills are received, matched, and paid within 15 days of service finalization if there is no written contract.
• If the bills are only received and logged in April, the aging calculation begins from the date of receipt, but the expense accrual remains valid for the preceding year if paid within the limits from the invoice date.

7. Reversing Disallowances in Subsequent Fiscal Years

If you are forced to pay tax on a disallowed MSME purchase in the current financial year, you can reclaim the deduction in the future. Section 43B(h) allows the deduction in the financial year in which the payment is actually released to the vendor. Ensure your tax advisor tracks these disallowed blocks to claim the offsets in subsequent return filings.

8. Difference Between Micro and Small Enterprise Definitions

Micro Enterprises are businesses with investments under Rs 1 crore and turnovers under Rs 5 crore. Small Enterprises are those with investments under Rs 10 crore and turnovers under Rs 50 crore. Section 43B(h) applies equally to both, but excludes Medium Enterprises.
