How to register for Udyam (MSME) and classify your business

How businesses are classified as micro, small, or medium

Classification is decided by two numbers: investment in plant and machinery or equipment, and annual turnover. Both must stay within the limits for a category. The higher classification applies if either number exceeds the limit.

The thresholds were last revised in March 2025 and took effect in April. A micro enterprise has investment up to ₹2.5 crore and turnover up to ₹10 crore. A small enterprise has investment up to ₹25 crore and turnover up to ₹100 crore. A medium enterprise has investment up to ₹125 crore and turnover up to ₹500 crore.

Export turnover is excluded from the calculation. If a business operates under multiple GST registrations but a single PAN, all entities are aggregated and assessed as one enterprise.

Why the composite criteria matter

The classification is composite, meaning both investment and turnover are tested together. A business only qualifies for a category if it stays within both limits at once.

For example, a manufacturer with ₹20 crore in investment but ₹120 crore in turnover does not qualify as small because its turnover has crossed into medium-enterprise territory, even though its investment is within the small limit.

How businesses move between MSME categories

Moving up is immediate. If a business crosses the ceiling for its current category in either investment or turnover, it is reclassified into the next tier up right away.

Moving back down requires the business to fall below the limit on both criteria simultaneously. Exceeding the threshold on just one was enough to push it up, but correcting just one is not enough to bring it back. This rule prevents businesses from cycling in and out of MSME status based on short-term fluctuations.

What counts toward investment and turnover

Investment is calculated on plant and machinery or equipment specifically, at depreciated cost as of 31 March each year. It does not include land, buildings, or working capital.

Turnover excludes export revenue entirely. This means a business selling heavily overseas can have export sales beyond its domestic turnover without that portion counting toward its classification.

If a business operates through multiple GST registrations under a single PAN, all of those entities are aggregated and assessed together as one enterprise.

Udyam registration vs Udyam Assist Platform

Udyam registration is the standard process for businesses with a PAN and filed income tax returns. It draws investment and turnover figures directly from tax and GST filings, reducing reliance on self-reported numbers.

The Udyam Assist Platform (UAP) is for informal micro enterprises without a PAN or filed ITRs. A bank, NBFC, or other designated agency registers the enterprise on its behalf. The resulting Udyam Assist certificate is treated as equivalent to micro-enterprise status for priority-sector lending purposes.

UAP was launched on 11 January 2023 and has onboarded over 145 designated agencies, facilitating registration of over 1.50 crore unique informal micro enterprises as of October 2026.

Why getting your MSME classification right matters

Classification is the gateway to securing an MSME loan and accessing almost every MSME-specific benefit. Development institutions like SIDBI rely strictly on official Udyam classification data to determine loan eligibility, extend concessional debt, and provide capital subsidies.

Misclassification can lead to loan rejection, loss of benefits, or legal complications. Getting the investment and turnover numbers right at the registration stage is critical.
