MSME Definition

An Indian small-business loan file should not start with “SME” as a loose sales label. For regulated lending, the operative category is micro, small and medium enterprise (MSME), and the proof point is the Udyam Registration Certificate (URC). The reason is practical: the URC drives eligibility for priority sector lending (PSL), collateral-free guarantee cover, delayed-payment remedies, public-procurement preferences, and many product-policy cut-offs used by banks and non-banking financial companies (NBFCs).

As of July 2026, the latest verified Ministry of MSME annual report available publicly is the Annual Report 2024-25; for live registration counts, the Ministry’s Udyam portal and performance dashboard are more current than the annual report. The Udyam factsheet on 16 July 2026 showed 9.02 crore Udyam plus Udyam Assist registrations, of which 8.96 crore were micro, 5.40 lakh small, and 41,668 medium enterprises; it also reported 39.87 crore employment linked to these registrations (Udyam Registration Portal, facts dated 16 July 2026). Those counts are registration counts, not a clean de-duplicated census of economically active firms, so lenders still run bureau, bank-statement, GST, field and fraud checks.

The current thresholds

The current definition is a composite test: both investment in plant and machinery or equipment and annual turnover must stay within the threshold. The Ministry’s Udyam portal states the revised limits effective from 1 April 2025 (Udyam portal, “Definition of MSMEs (Pre & Post 01-04-2025)”):

Class	Investment not exceeding	Turnover not exceeding
Micro	₹2.5 crore	₹10 crore
Small	₹25 crore	₹100 crore
Medium	₹125 crore	₹500 crore

The change came through the Modified Notification on Revision of MSME Definition Effective From 01.04.2025, posted by the Ministry on 21 March 2025 (Udyam Circulars & Orders). It implemented the Union Budget 2025-26 proposal to raise investment limits by 2.5 times and turnover limits by 2 times; the Budget release showed the old-to-new movement from ₹1 crore/₹5 crore to ₹2.5 crore/₹10 crore for micro, ₹10 crore/₹50 crore to ₹25 crore/₹100 crore for small, and ₹50 crore/₹250 crore to ₹125 crore/₹500 crore for medium (PIB, Ministry of Finance, 1 February 2025).

This sounds simple, but credit teams should note three details.

First, the test is composite. If a unit has ₹2 crore of equipment and ₹14 crore of turnover, it is not micro because turnover breaches ₹10 crore. It may be small if investment and turnover both fit the small thresholds. Second, exports are excluded for some Udyam classification calculations under the 2020 framework, but a lender should not rely on a borrower’s spreadsheet for this; the URC classification is the usable operating artifact. Third, the 2025 revision changed the practical boundary for many “upper small” and “lower medium” borrowers. A manufacturer with ₹80 crore turnover and ₹18 crore machinery investment that would previously have been medium can now sit in small, which can affect PSL reporting and CGTMSE product design.

Udyam and Udyam Assist

Udyam Registration is online, paperless and based on self-declaration. The official portal says no documents are uploaded for registration, Aadhaar is required for the proprietor/managing partner/karta or authorised signatory, PAN and GST-linked investment/turnover data are pulled from government databases, and only one Udyam registration is allowed per enterprise, with multiple activities permitted in the same registration (Udyam portal). The certificate has a permanent Udyam Registration Number and dynamic QR code.

The Udyam Assist Platform (UAP) exists for informal micro enterprises (IMEs), especially non-GST micro borrowers who otherwise do not have tax-system data. The Ministry says UAP was launched on 11 January 2023 to bring IMEs into the formal ambit, and banks, NBFCs and other lending institutions can act as authorised partners to help issue Udyam Assist Certificates (PIB, 14 July 2026). In practice, this matters for microfinance institutions (MFIs), small finance banks (SFBs), and NBFCs lending to kirana stores, repair shops, small traders and home-based units that are economically real but GST-invisible.

Why the definition matters to lenders

The Reserve Bank of India (RBI) has deliberately moved banks away from maintaining their own parallel MSME classification tables. In Classification of MSMEs, RBI circular RBI/2023-24/100, FIDD.MSME & NFS.BC.No.13/06.02.31/2023-24, dated 28 December 2023, RBI said classification or re-classification is the statutory responsibility of the Ministry of MSME and that regulated entities should be guided by Ministry notifications. It amended the MSME lending Master Direction to say that for PSL purposes, banks shall be guided by the classification recorded in the URC (RBI circular, 28 December 2023).

That single sentence changes operations. A bank’s loan origination system (LOS) should capture the URN, certificate date, current classification, NIC activity, enterprise type, PAN, GSTIN where applicable, and whether the customer came through UAP. It should also store the fetched certificate or verification response, because downstream PSL reporting, guarantee cover, monitoring and audit will rely on it. For working-capital borrowers, annual renewal should include a Udyam re-check, especially after turnover jumps, merger/reconstitution, GST migration or change in constitution.

Product and policy implications

For the lender, “MSME” is not a single risk segment:

Micro often means ₹50,000 to ₹25 lakh loans, owner-managed cash flows, thin bureau files, UAP/Udyam as identity, and underwriting through bank statement, GST where available, merchant acquiring, UPI, or field verification.
Small often covers ₹25 lakh to ₹10 crore exposure, formal bank accounts, GST returns, cash-credit limits, machinery finance, loan against property (LAP), receivable finance and CGTMSE-backed programs.
Medium may look closer to corporate banking: audited financials, multiple banking arrangements, working-capital consortium or multiple banking, collateral packages, ratings, stock statements, and covenant monitoring.

The classification also interacts with guarantee and PSL rules. All bank loans to eligible MSMEs qualify under the MSME category of PSL under Master Directions - Reserve Bank of India (Priority Sector Lending - Targets and Classification) Directions, 2025, effective 1 April 2025, and the micro-enterprise sub-target remains a hard planning constraint for banks (RBI PSL Directions, 24 March 2025). CGTMSE separately covers eligible micro and small enterprise credit facilities up to ₹10 crore from 1 April 2025, but the guarantee scheme is not a substitute for underwriting; it changes loss-given-default economics and capital allocation, not the borrower’s cash flow (DC-MSME Credit Guarantee Scheme page).

Practical exceptions and checks

The URC is necessary but not sufficient. Common credit-file issues include a proprietor using personal PAN banking for the business, a GSTIN belonging to a different legal constitution, a family group splitting turnover across multiple Udyams, a borrower classified as trader but seeking machinery finance, and old UAM/EM-II certificates presented instead of Udyam. The operating answer is not to reject blindly; it is to reconcile constitution, bank account name, PAN, GSTIN, shop/establishment proof, invoices and bureau records before sanction.

For system design, treat classification as a time-stamped external attribute, not a permanent borrower field. A borrower can move from micro to small as turnover grows, and the lending system must preserve historical classification for old PSL reports while using the current classification for new disbursements.
