MSME Section 16 (MSMED Act, 2006): Compound interest at 3× bank rate (currently 3 × 6.65% = 19.95% p.a.) from the day after the due date. MSME payment must be made within 45 days of invoice (or agreed credit period, whichever is less). Section 43B(h) of Income Tax Act also disallows deduction for the payer until actually paid.
