⚖️ Section 16 of the MSMED Act, 2006:

Where any buyer fails to make payment to the supplier as required under Section 15, the buyer shall, notwithstanding anything contained in any agreement between the buyer and the supplier, be liable to pay compound interest with monthly rests to the supplier on that amount from the appointed day, at three times of the bank rate notified by the Reserve Bank.

Understanding Section 16 of the MSMED Act, 2006

To protect Micro and Small enterprises from working capital crunches due to delayed payments, the Indian Government enacted the Micro, Small and Medium Enterprises Development (MSMED) Act, 2006.

Under Section 15 of the Act, buyers must clear payments within the agreed timeframe, which cannot exceed 45 days from the date of acceptance of goods or services.

⚖️ Penal Interest under Section 16:

If the buyer fails to pay within 45 days, they are legally liable to pay compound interest with monthly rests to the supplier. The interest rate is fixed at three times (3x) the Bank Rate notified by the RBI. Note that this interest is penal and cannot be claimed as a tax deduction by the buyer.

Compounding Monthly Formula

MSME interest is compounded at "monthly rests" (compounded monthly). The compound interest is calculated using the formula:

A = P * (1 + (3 * Repo Rate) / 12) ^ n
Interest Due = A - P

Where P is the invoice amount, Repo Rate is the RBI repo rate (e.g. 6.5%), and n is the delay period expressed in months.

How to Post Interest Debit Notes in Tally?

Once you compute the delayed interest, you must issue a Debit Note to the customer to record the interest receivable:

  1. Enable Interest Calculation in Tally Prime via F11 Statutory/Features > Enable Interest Calculation.
  2. Configure the Ledger: Go to Gateway of Tally > Ledger > Alter > Select Customer Ledger. Enable "Activate Interest Calculation" and set parameters (19.5% annual rate, compounded monthly).
  3. Post a Debit Note: Go to Vouchers > F9 Debit Note. Select the Interest Class to auto-populate the accumulated interest, or enter the calculator's value manually to bill the customer.
