Composite Criteria
Investment + Turnover Test
MSME classification combines investment in plant & machinery / equipment AND annual turnover — both criteria must be satisfied; the higher classification applies.

FAQs on Udyam Registration
What is Udyam Registration and is it mandatory?
Udyam Registration is the official MSME (Micro, Small, Medium Enterprise) recognition issued by the Ministry of MSME under the MSMED Act 2006 through the Udyam portal (udyamregistration.gov.in) since 1 July 2020. It replaced the earlier Udyog Aadhaar Memorandum (UAM) regime. While it is not mandatory by law for every business to register, holding a Udyam certificate is essentially required to claim any MSME benefit — priority-sector lending, CGTMSE collateral-free loans, Sec 15 delayed-payment protection, Public Procurement Policy preference, GeM seller benefits, ISO / patent-fee subsidies, electricity rebates, and Sec 43B(h) buyer-side compliance. Without Udyam, the business is treated as a non-MSME for these purposes.
What is the new MSME classification under composite criteria?
Effective from 1 April 2025, the revised composite criteria for MSME classification are: Micro Enterprise — investment in plant & machinery / equipment up to ₹2.5 crore AND turnover up to ₹10 crore; Small Enterprise — investment up to ₹25 crore AND turnover up to ₹100 crore; Medium Enterprise — investment up to ₹125 crore AND turnover up to ₹500 crore. Both criteria — investment and turnover — must be satisfied simultaneously; if any one parameter exceeds the limit, the enterprise moves to the next higher category. Manufacturing, services, and traders are all covered under this same classification matrix post the 2021 inclusion of trade activity.
What is the Section 15–24 delayed-payment protection?
Sections 15 to 24 of the MSMED Act 2006 create a powerful payment-discipline framework for buyers dealing with registered MSMEs. Sec 15 mandates payment to a Micro or Small Enterprise within the agreed credit period or, where unspecified, within 45 days from the day of acceptance / deemed acceptance of goods or services. Sec 16 imposes mandatory compound interest at 3x the bank rate notified by RBI from the day immediately after the appointed day, payable to the supplier without any further notice. Sec 18 permits the supplier to file a recovery case before the MSEFC (Micro and Small Enterprises Facilitation Council) for arbitration / conciliation. The benefit is available only to Udyam-registered Micro and Small Enterprises (not Medium).
What is Section 43B(h) of the Income-tax Act and why does it matter?
Section 43B(h), inserted by the Finance Act 2023 effective AY 2024-25, disallows any deduction in the hands of a buyer for an amount payable to a Micro or Small Enterprise beyond the time limit specified in Section 15 of the MSMED Act (i.e., 45 days or the agreed period, whichever is less). The deduction is allowed only in the year of actual payment — not on accrual. This creates a significant cash-flow incentive for corporate buyers to pay registered MSMEs on time. Practical impact: corporate buyers now insist on collecting MSME / Udyam certificates from all vendors to identify and prioritise such payables, and many CFOs run quarterly Sec 43B(h) compliance checks before book closure.
How long does Udyam registration take and how much does it cost?
Udyam Registration is completely free of any government fee — there is no charge for filing on the official Udyam portal. With Aadhaar e-KYC and proper documentation, the registration is typically completed same-day to next-day, with the Udyam Registration Number (URN) and Udyam Certificate issued online. Beware of unofficial third-party sites that mimic the Udyam portal and charge fees — always file through udyamregistration.gov.in (the official Ministry of MSME website). Professional consulting fees may be charged for advisory, classification mapping, document preparation, and post-registration scheme support, but the government registration itself is free.
What happens when an MSME crosses the threshold and graduates to the next tier?
On crossing the investment or turnover threshold of its current category, the Udyam system automatically reclassifies the enterprise based on data fetched from ITR and GSTR. However, the MSMED framework provides a 3-year transition window for non-tax-related benefits — meaning the enterprise continues to enjoy benefits of the prior (lower) category for up to 3 years even after auto-graduation, in respect of schemes such as PSU tender preference, certain subsidies, etc. Tax-related benefits (such as Sec 15 delayed-payment protection or Sec 43B(h) buyer-side application) are based on the current classification at the relevant date, not the legacy classification.
Can a trader register under Udyam?
Yes — since July 2021, the Ministry of MSME expressly recognised Wholesale and Retail Traders as eligible for Udyam Registration, opening up the MSME ecosystem to a vast trader base that was earlier excluded. Traders use the relevant NIC codes for trade activity while registering. Trader Udyam registration unlocks priority-sector lending status with banks, TReDS bill-discounting platform onboarding, GeM seller benefits, and CGTMSE access. However, certain MSME schemes (such as PMEGP credit-linked subsidy and some industrial-sector incentives) remain reserved for manufacturing and select service categories — traders should confirm scheme-by-scheme eligibility before relying on a particular benefit.
