Udyam registration is the official MSME registration on the Udyam portal, notified by the Ministry of MSME under the MSMED Act, 2006. It is free, PAN and Aadhaar linked, and classifies an enterprise from its investment and turnover. Under notification S.O. 1364(E), effective 1 April 2025, a micro enterprise has investment up to Rs 2.5 crore and turnover up to Rs 10 crore.

What is Udyam registration?

Udyam registration is the official registration that classifies an enterprise as a micro, small or medium enterprise (MSME) in India. It is done on the Udyam portal at udyamregistration.gov.in, run by the Ministry of Micro, Small and Medium Enterprises. Section 8 of the MSMED Act, 2006 requires an enterprise to file a memorandum, and Udyam registration is the form that memorandum now takes.

The registration produces a permanent Udyam Registration Number and an e-certificate. Classification is not chosen by the applicant. It is derived from the enterprise's investment in plant, machinery or equipment and its annual turnover, both of which the portal reads from linked income tax and GST records.

What are the MSME classification limits?

The current limits were set by notification S.O. 1364(E) dated 21 March 2025, effective 1 April 2025, which revised the earlier 2020 thresholds. A micro enterprise has investment up to Rs 2.5 crore and turnover up to Rs 10 crore. A small enterprise has investment up to Rs 25 crore and turnover up to Rs 100 crore. A medium enterprise has investment up to Rs 125 crore and turnover up to Rs 500 crore. Both limits apply together, so breaching either one moves the enterprise up a category.

CategoryInvestment (up to)Turnover (up to)
MicroRs 2.5 croreRs 10 crore
SmallRs 25 croreRs 100 crore
MediumRs 125 croreRs 500 crore

A single composite standard now applies to both manufacturing and service enterprises. The earlier split between the two sectors was removed when the composite investment-and-turnover criteria came in.

What were the earlier limits?

The previous limits came from notification S.O. 2119(E) dated 26 June 2020, effective 1 July 2020. Under those figures a micro enterprise had investment up to Rs 1 crore and turnover up to Rs 5 crore, a small enterprise up to Rs 10 crore and Rs 50 crore, and a medium enterprise up to Rs 50 crore and Rs 250 crore. Reading an old certificate against the current limits is a common source of misclassification.

Is Udyam registration free?

Udyam registration is free on the official portal. The Ministry of MSME states there is zero cost and no fee, and that no other website, portal or app is official. The registration is PAN and Aadhaar linked: the Aadhaar of the proprietor, partner, director or authorised signatory is used to authenticate, and the enterprise PAN anchors the record.

The portal auto-fetches investment and turnover figures from the income tax return and GST data tied to that PAN, so the applicant does not upload financial documents. PAN and GSTIN are required where the enterprise is required to hold GST registration under the CGST Act. An enterprise genuinely outside GST registration does not need a GSTIN to complete Udyam registration.

How does Udyam differ from Udyog Aadhaar?

Udyam registration replaced Udyog Aadhaar Memorandum (UAM) and the older Entrepreneurs Memorandum Part-II (EM-II) from 1 July 2020. The difference is not cosmetic. Udyam pulls investment and turnover automatically from ITR and GST records, while UAM relied on self-declared figures. Udyam also issues a single permanent number and a verifiable e-certificate.

FeatureUdyam registrationUdyog Aadhaar / EM-II
StatusCurrent system since 1 July 2020Retired, re-registration required
Data sourceAuto-fetch from ITR and GSTSelf-declared figures
IdentifierUdyam Registration NumberUdyog Aadhaar Number or EM-II
Sector splitNone, single composite standardManufacturing and service treated apart

An enterprise still holding a Udyog Aadhaar number should register afresh on the Udyam portal. UAM validity was extended in stages after 2020 before it ceased, and MSME benefits now run off a Udyam Registration Number.

How does Udyam link to section 43B(h)?

A Udyam registration as a micro or small enterprise is what pulls a supplier's invoice into the 45-day payment rule. Section 15 of the MSMED Act, 2006 caps the buyer's payment period at 45 days where there is a written agreement, and 15 days where there is none. Section 43B(h) of the Income-tax Act then denies the buyer a deduction for that purchase until the year it is actually paid, unless payment falls inside the section 15 window.

The link is the registration. Section 43B(h) bites only where the supplier is a micro or small enterprise registered under the MSMED Act, which in practice means the supplier holds a Udyam Registration Number in the micro or small category. The full mechanics, including the year the deduction shifts to, are in the section 43B(h) MSME payment guide.

How do I verify a Udyam number?

  1. Open the Verify Udyam Registration page on the official portal.
  2. Enter the Udyam Registration Number exactly as printed on the certificate.
  3. Read the enterprise name and its current micro, small or medium status from the portal result.
  4. For your own registration, use the Print Udyam Certificate login to pull the live certificate rather than an emailed copy.

The portal figure is the record that matters, because classification can change when investment or turnover crosses a limit. A certificate printed a year ago may show a category the enterprise has since moved out of.

Why do Udyam registrations go wrong?

  • Paying a third-party website that mimics the portal, when the official registration at udyamregistration.gov.in is free.
  • Reading an old certificate against the current limits, so an enterprise still calls itself micro after crossing Rs 10 crore turnover.
  • Keeping a lapsed Udyog Aadhaar number instead of re-registering on the Udyam portal.
  • Assuming a medium enterprise supplier is covered by section 43B(h), when only micro and small registrations trigger the 45-day rule.
  • Treating a self-declared turnover as the classification, when the portal uses the ITR and GST figures tied to the PAN.

Where are MSME rules notified?

MSME classification limits, the Udyam framework and the delayed-payment provisions move through the Ministry of MSME and interact with income tax and corporate law. Complied AI keeps MCA and corporate updates in one feed so you can open the source behind a change. When the payment side is the question, read the section 43B(h) guide next to the classification notification.

Practical checks

Common questions

Is Udyam registration mandatory?

Udyam registration is not forced on every business, but it is the only way to be recognised as an MSME and claim MSME benefits. Section 8 of the MSMED Act, 2006 makes the memorandum, now filed as Udyam registration, the basis for classification. Without it an enterprise cannot access priority sector lending, the delayed-payment protection in section 15, or MSME government scheme benefits.

Does Udyam registration cost anything?

No. Udyam registration is free on the official portal at udyamregistration.gov.in. The Ministry of MSME states there is zero cost and no fee, and that no other website, portal or app is official. Any site charging a fee for Udyam registration is not the government portal.

I have Udyog Aadhaar. Do I need to move to Udyam?

Yes. Udyog Aadhaar Memorandum (UAM) and the older EM-II were replaced by Udyam registration from 1 July 2020. Existing UAM holders had to re-register on the Udyam portal, and the government extended UAM validity in stages before it ceased. A live MSME today runs on a Udyam Registration Number, not a Udyog Aadhaar number.

My turnover crossed Rs 10 crore. Am I still micro?

No. Under notification S.O. 1364(E), effective 1 April 2025, a micro enterprise must have investment up to Rs 2.5 crore and turnover up to Rs 10 crore. Cross either ceiling and the enterprise moves up to small, which allows investment up to Rs 25 crore and turnover up to Rs 100 crore. Classification uses the higher category once any one limit is breached.

Do I need GST to register on Udyam?

It depends on whether GST law requires you to register for GST. PAN and GSTIN are required for Udyam registration where the enterprise is required to hold GST registration under the CGST Act. An enterprise genuinely exempt from GST registration does not need a GSTIN to complete Udyam registration.

How does Udyam help me get paid within 45 days?

A Udyam registration as a micro or small enterprise brings the supplier under section 15 of the MSMED Act, 2006, which caps the buyer's payment period at 45 days where there is a written agreement, and 15 days where there is none. It also triggers section 43B(h) of the Income-tax Act on the buyer's side, so a late payer loses the deduction until the year of actual payment.

How do I check if a supplier's Udyam number is real?

Use the Verify Udyam Registration page on the official Udyam portal and enter the Udyam Registration Number. The portal shows the enterprise name and its current micro, small or medium status. This is the check a buyer should run before relying on section 43B(h) for a supplier's invoice.
