Tamil Nadu has more than 62 lakh enterprises on the Udyam portal, third among states. Over 99% are micro units, and the 2025 change in MSME definitions quietly cut the number of small and medium firms by a third. Here is how to read the count.
The numbers
As of 28 February 2026, Tamil Nadu had 62,27,609 enterprises registered on the Udyam Registration Portal and the Udyam Assist Platform, according to the MSME ministry. Only Maharashtra (1.01 crore) and Uttar Pradesh (86.03 lakh) had more. Nationally, registrations crossed 7.83 crore.
The headline hides the shape. The ministry’s Annual Report 2025-26 counts, as on 31 January 2026, 60,08,953 micro, 39,259 small and 2,822 medium enterprises in Tamil Nadu. Micro units are 99.3% of the total. And between December 2024 and January 2026, the state’s count of small enterprises fell from 59,838 to 39,259, and medium from 5,322 to 2,822, not because firms closed but because the definitions changed.
What Udyam registration is
Udyam is the free, online, self-declared registration for micro, small and medium enterprises, which replaced earlier systems from 1 July 2020. A registered unit can claim MSME benefits such as priority-sector lending, credit guarantees and protection against delayed payment. The Udyam Assist Platform brings informal micro enterprises, many without the documents the main portal needs, into the count, and the ministry’s state totals include them.
Because registration is self-declared and has no renewal test of activity, the count measures enterprises that have registered, not enterprises currently operating. It includes traders and service providers as well as manufacturers.
Five years of registrations
| Period | TN registrations | Basis |
|---|---|---|
| 2020-21 | 3,12,149 | registered in year |
| 2021-22 | 5,41,307 | registered in year |
| 2022-23 | 7,31,753 | registered in year |
| 2023-24 (to 4 Dec 2023) | 11,19,887 | registered in period |
| Cumulative, 4 Dec 2023 | 27,05,096 | total |
| Cumulative, 31 Dec 2024 | 47,19,261 | total incl. Udyam Assist |
| Cumulative, 31 Jan 2026 | 60,51,034 | total incl. Udyam Assist |
| Cumulative, 28 Feb 2026 | 62,27,609 | total incl. Udyam Assist |

The count more than doubled in the 26 months from December 2023 to February 2026. Much of that growth reflects the spread of Udyam Assist and bank-led registration drives, not a doubling of business activity. Tamil Nadu’s share of the national total, about 7.95% in January 2026, is about half its 15% share of India’s registered factories.
How the 2025 definitions moved the numbers
From 1 April 2025, under a notification of 21 March 2025, the investment and turnover limits were raised: micro to ₹2.5 crore of plant and machinery and ₹10 crore turnover, small to ₹25 crore and ₹100 crore, and medium to ₹125 crore and ₹500 crore. A firm that was small under the old limits could now be micro; a medium firm could become small. Because limits apply to both investment and turnover, a unit’s category can also change as it grows, so the micro share is a snapshot, not a fixed feature of the economy.
| Tamil Nadu | 31 Dec 2024 | 31 Jan 2026 | Change |
|---|---|---|---|
| Micro | 46,54,101 | 60,08,953 | +29% |
| Small | 59,838 | 39,259 | −34% |
| Medium | 5,322 | 2,822 | −47% |
| Total | 47,19,261 | 60,51,034 | +28% |

The same pattern shows nationally: small enterprises fell from 7,32,782 to 4,88,688 and medium from 69,013 to 36,816 over the same period. For a Chennai firm, being reclassified downward is usually an advantage: micro units get the most favourable treatment under several schemes, and the 45-day payment protection applies to micro and small suppliers.
Share of India’s 7.61 crore Udyam registrations in trading as on 31 January 2026 (3.29 crore), against 21% in manufacturing (MSME Annual Report 2025-26).
It’s often said Tamil Nadu’s 62 lakh MSMEs are 62 lakh factories and workshops.
The record shows Udyam counts self-registered enterprises of every kind, and nationally traders outnumber manufacturers two to one. The Annual Survey of Industries counted 41,221 registered factories in Tamil Nadu in 2024-25.
Women owners and the Chennai question
Nationally, the same December 2023 release counted 1,17,36,406 women-owned enterprises, about 37.1% of 3.16 crore registrations, so Tamil Nadu’s share of women owners was close to the national average rather than above it. Across India, services made up 2.73 crore of the 7.61 crore registrations in January 2026, about 36%, which suggests the same mix of shops, services and small workshops behind Tamil Nadu’s total, though the annual report does not give the state’s sector split.
The ministry’s December 2023 release counted 9,90,165 women-owned registered MSMEs in Tamil Nadu, about 36.6% of the state’s 27.05 lakh registrations then. Later state-wise ownership figures were not published in the documents reviewed.
District figures are available on the MSME dashboard but could not be opened for this article, so a Chennai-only count is not given here. For scale, the ASI 2024-25 makes the point that registered factories, 41,221 in the state, are a tiny fraction of Udyam’s universe.
The national registration curve
Tamil Nadu’s growth tracks a national surge. The ministry’s March 2026 release gives cumulative registrations of 0.79 crore at the end of 2021-22, 1.64 crore in 2022-23, 4.12 crore in 2023-24, 6.19 crore in 2024-25 and 7.83 crore by 28 February 2026. The steepest jump, in 2023-24, coincides with the spread of the Udyam Assist route for informal units.
Registration feeds credit. The Annual Report 2025-26 reports that the Credit Guarantee Fund Trust for Micro and Small Enterprises (CGTMSE) has approved over 1.18 crore guarantees worth ₹9.80 lakh crore since inception, ₹3 lakh crore of it in 2024-25. Guarantees let banks lend to small firms without collateral, and Udyam registration is the usual entry ticket.
What this means for you
- Registration is free on the official Udyam portal; agents charging a fee are not required.
- If your firm was ‘small’ before April 2025, check whether it is now ‘micro’; benefits and payment protections can change.
- Udyam numbers measure registrations, not active businesses; use them to track formalisation, not economic output.
- Women-owned units were over a third of Tamil Nadu’s registrations in 2023; several schemes reserve benefits for them.
