The Micro, Small and Medium Enterprises Development (MSMED) Act, 2006 provides robust statutory mechanisms to safeguard micro and small suppliers from working-capital erosion caused by delayed commercial payments. Under Sections 15, 16, and 17 of the Act, buyers who purchase goods or services from a registered Micro or Small Enterprise (MSE) are legally bound to settle invoices within prescribed deadlines. Failure to do so triggers a non-negotiable statutory obligation to pay penal compound interest with monthly rests at three times the Bank Rate notified by the Reserve Bank of India.
1. Statutory Payment Deadlines Under Section 15
Section 15 of the MSMED Act establishes strict statutory timelines for commercial invoice payments:
- Agreed Period: Where buyer and supplier have executed a written commercial contract specifying a credit term, payment must be made on or before the agreed date. However, the statute categorically mandates that such agreed period shall not exceed 45 days from the day of acceptance or deemed acceptance. Any contractual clause stipulating credit terms exceeding 45 days is void ab initio.
- No Written Agreement: Where no formal written agreement exists, the statutory payment deadline is the 15th day following the day of acceptance or deemed acceptance of goods or services.
- Day of Deemed Acceptance: If the buyer does not intimate any formal objection regarding quality or specifications in writing within 15 days of delivery, the supply is legally deemed accepted on the date of actual physical delivery.
2. Statutory Interest Formula Under Section 16
If the buyer defaults on paying the supplier on or before the statutory due date, Section 16 mandates payment of penal interest. The statutory formula is uniquely structured:
Statutory Interest Rate = 3 × RBI Bank Rate
Compounded with monthly rests (monthly compounding). Daily interest across incomplete months is applied pro-rata based on the accrued principal plus accumulated monthly interest.
With the Reserve Bank of India's current notified Bank Rate standing at 6.75% per annum, the statutory interest rate for delayed MSME payments is:
Penal Interest Rate = 3 × 6.75% = 20.25% per annum (Compounded Monthly)
3. Comprehensive Worked Example
Consider an auto-component manufacturer registered as a Small Enterprise with Udyam Registration that delivers machine spares worth ₹5,00,000 to a corporate buyer on 1st April 2026 under a written 45-day credit agreement:
| Calculation Parameter | Statutory Determination |
|---|---|
| Date of Physical Delivery | 01 April 2026 |
| Statutory Payment Due Date (45 Days) | 16 May 2026 |
| Actual Settlement Date | 15 July 2026 |
| Total Overdue Delay Period | 60 Days |
| Applicable Statutory Rate | 20.25% p.a. (3 × 6.75% Bank Rate) |
| Compounded Interest Accrued | ₹17,064 |
| Total Legally Recoverable Amount | ₹5,17,064 |
4. Mandatory Disallowance Under Section 23 of Income Tax Act
A critical enforcement pillar of the MSMED Act is Section 23, which explicitly provides that notwithstanding anything contained in the Income Tax Act, 1961, the amount of interest paid or payable by a buyer under the MSMED Act cannot be deducted as business expenditure when computing taxable income. This provisions imposes a severe financial penalty on corporate debtors who delay MSE payments.

Statutory MSME Samadhaan Filing & Insolvency Interaction
When buyer default exceeds 45 days, registered MSE suppliers can initiate recovery proceedings online through the official MSME Samadhaan Portal. Applications filed under Section 18 of the MSMED Act are automatically assigned to the Micro and Small Enterprises Facilitation Council (MSEFC) within whose jurisdiction the supplier is situated, irrespective of jurisdiction clauses in commercial invoices. Furthermore, under Section 19 of the Act, if the buyer challenges an award decreed by the Facilitation Council before an appellate court, the appeal cannot be entertained unless the buyer deposits 75% of the awarded amount including compound interest in court.
Under the Insolvency and Bankruptcy Code (IBC), 2016, unpaid MSE suppliers qualify as operational creditors and may initiate Corporate Insolvency Resolution Process (CIRP) under Section 9 if the operational default meets the statutory threshold, providing strong dual statutory leverage to secure prompt payment.
