Calculators / Udyam Checker
Validate a supplier’s Udyam registration number and see what MSME status means for you as a buyer: the 45-day payment rule, the MSME-1 half-yearly return, and the Section 43B(h) tax disallowance for late payments.

Why it matters to a buyer
| If the supplier is a registered MSME | Your obligation |
|---|---|
| Payment terms | Pay within 45 days of acceptance (15 days if no written agreement), else interest at 3x the RBI bank rate, compounded monthly (Sec 15-16, MSMED Act) |
| MSME-1 return | Report amounts outstanding beyond 45 days in the half-yearly MSME-1 (30 April and 31 October); see the compliance calendar |
| Income tax | Section 43B(h): amounts unpaid beyond the MSMED time limit are disallowed in the year, allowed only on actual payment (micro and small suppliers) |
| Financial statements | Disclose MSME dues, interest paid or payable, under Sec 22 MSMED and Schedule III |
