Section 43B(h) of the Income Tax Act has fundamentally restructured commercial credit terms across India. Designed to ensure timely cash flow to Micro and Small enterprises, this provision disallows business expense deductions if payments are not settled within strict statutory timelines.
What is Section 43B(h) of the Income Tax Act?
Introduced via the Finance Act, Section 43B(h) provides that any sum payable by an assessee to a Micro or Small enterprise beyond the time limit specified in Section 15 of the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006 will only be allowed as an income tax deduction in the financial year in which the sum is actually paid, rather than on an accrual basis.
Applicable Payment Timelines under MSMED Act
The statutory deadlines depend strictly on whether a written commercial contract exists between the buyer and supplier:
| Scenario | Statutory Payment Deadline |
|---|---|
| No written agreement | Within 15 days from the date of acceptance/delivery of goods or services. |
| Written agreement exists | As per agreed credit terms, but strictly not exceeding 45 days. |
Crucial Note: Even if both parties mutually sign a 60-day or 90-day credit agreement, the law caps the maximum permissible credit period at 45 days for Section 43B(h) purposes.
Who is Covered and Who is Exempt?
- Covered: Suppliers registered as Micro (Investment < ₹1 Cr & Turnover < ₹5 Cr) or Small (Investment < ₹10 Cr & Turnover < ₹50 Cr) engaged in manufacturing or service provision with a valid Udyam Registration.
- Exempt: Medium Enterprises (Turnover > ₹50 Cr) are completely outside Section 43B(h).
- Wholesale & Retail Traders: Although traders can register on Udyam for priority sector bank lending, CBDT and Ministry clarifications hold that wholesale and retail traders are not eligible for the payment protections under Section 15 of the MSMED Act.
- Presumptive Taxation: Businesses filing returns under Section 44AD / 44ADA are exempt from Section 43B(h) disallowances.
Financial Consequences of Non-Compliance
- Expense Disallowance & Higher Income Tax: If you owe ₹30 Lakhs to MSME vendors as of March 31st and pay after the 45-day window, that ₹30 Lakhs is added back to your taxable net profit. At a corporate tax rate of 25% or 30%, you will face an unexpected cash tax outgo of up to ₹9 Lakhs plus surcharges.
- Compounded Penal Interest: Under Section 16 of the MSMED Act, delayed payments attract penal interest at three times the RBI Bank Rate, compounded monthly. Crucially, this penal interest is permanently disallowed as a business expense under Section 23 of the MSMED Act.
Action Checklist for Business Owners & CFOs
- Identify & Tag MSME Vendors: Issue an annual declaration circular to all vendors requesting their active Udyam Registration Certificate and classification (Micro/Small/Medium/Trader).
- Review Purchase Orders & Invoices: Clearly state agreed credit terms (up to 45 days) in purchase agreements and invoices.
- March 31st Year-End Cleanup: Review outstanding trade payables aging report before fiscal year-end and prioritize settlement of Micro and Small enterprise invoices to prevent disallowance.
- Tax Audit Report (Form 3CD): Chartered Accountants are legally required to report delayed MSME payments under Clause 22 of Form 3CD.
