What is MSME Return (MSME Form-1)?
MSME Form 1 is the e-form by which specified companies disclose to the ROC the dues pending beyond 45 days to micro and small enterprise suppliers. It links to Section 15 of the MSMED Act, 2006, which requires buyers to pay MSMEs within 45 days or the agreed shorter period. It covers only micro and small suppliers, not medium enterprises.
A related provision, Section 43B(h) of the Income Tax Act, can disallow the expense for unpaid MSME dues beyond the permitted period. Penalty for non-filing under Section 405(4) is Rs 20,000 on the company and on every officer in default, according to ClearTax.
