What is Udyam registration?
The official online registration that classifies a business as a Micro, Small or Medium Enterprise under the MSMED Act, 2006.
Does it cost anything?
No. There is zero government fee and the process is fully paperless and Aadhaar based.
What are the new limits?
From 1 April 2025, Micro is up to Rs 2.5 crore investment and Rs 10 crore turnover.
Who can register?
Any proprietorship, partnership, LLP, company, trust or society engaged in manufacturing, services or trade.
Is it linked to tax?
Yes. Section 43B(h) of the Income Tax Act ties buyer deductions to timely payment of registered Micro and Small suppliers.
If you run a small business in India and have ever been asked for an MSME certificate by a bank, a buyer or a tender portal, that certificate comes from Udyam registration. From 1 April 2025 the qualifying limits were raised sharply, which means many businesses that were once excluded now qualify. This guide explains what Udyam registration is, who needs it, the revised limits, the exact online steps and the benefits worth claiming.
What is Udyam registration?
Udyam registration is the official process of recognising an enterprise as a Micro, Small or Medium Enterprise (MSME) under the Micro, Small and Medium Enterprises Development Act, 2006, through the Government of India Udyam portal. On registration the enterprise receives a permanent 12-digit Udyam Registration Number (URN) and a digital e-certificate.
Classification uses a composite criterion, which means both the investment in plant, machinery or equipment and the annual turnover must stay within the limit for a given category. The portal pulls investment data from your income tax records and turnover data from your GST returns, and recalculates your category automatically every financial year.
Key terms explained
- MSME: Micro, Small and Medium Enterprise, the umbrella category defined under the MSMED Act, 2006.
- URN: Udyam Registration Number, the unique 12-digit identifier issued on registration, with lifetime validity.
- Composite criterion: Classification based on both investment and turnover together, not either one alone.
- Udyam Assist Platform: A separate route that helps informal micro enterprises register through approved agencies.
Who needs Udyam registration?
Any enterprise engaged in manufacturing, services or trade can register, including proprietorships, partnership firms, LLPs, private and public companies, co-operative societies, trusts and Hindu Undivided Families. Since July 2021, retail and wholesale traders are also eligible.
Registration is voluntary, but it is effectively mandatory in practice if you want collateral-free credit, a place on government tender portals, the 45-day payment protection for suppliers, or any of the subsidy schemes reserved for MSMEs.
Legal framework
Udyam registration operates under the MSMED Act, 2006, administered by the Ministry of Micro, Small and Medium Enterprises. The revised classification limits were notified through S.O. 1364(E) dated 21 March 2025, effective 1 April 2025, raising the investment ceilings by 2.5 times and the turnover ceilings by 2 times.
The most important tax linkage is Section 43B(h) of the Income Tax Act, 1961. A buyer can claim a tax deduction for an amount payable to a registered Micro or Small enterprise only in the year it is actually paid, if payment is not made within the time allowed under Section 15 of the MSMED Act (15 days, or up to 45 days where there is a written agreement).
How to register on the Udyam portal: step by step
Visit the official portal. Go to udyamregistration.gov.in. Use only the government domain, since lookalike sites often charge a fee for a free service.
Choose your applicant type. Select the option for new entrepreneurs who are not yet registered as MSME.
Enter Aadhaar and validate by OTP. Provide the Aadhaar of the proprietor, managing partner or authorised director and verify with the OTP sent to the linked mobile number.
Add PAN and GST details. Enter the enterprise PAN and GSTIN. The portal validates these and fetches investment and turnover figures from linked records.
Fill the enterprise details. Add the business name, type, address, bank account, primary activity and number of employees.
Submit and get the certificate. Accept the self-declaration, submit with the final OTP, and the Udyam e-certificate with QR code is generated and emailed to you.
Documents and prerequisites
Aadhaar number of the proprietor, partner or director (mandatory).
PAN of the enterprise.
GSTIN, where the business is required to be registered under GST.
Bank account details of the enterprise.
Investment and turnover figures, which the portal largely auto-fetches.
Good to know: No documents are uploaded. Udyam is a self-declaration system, so accuracy of the figures you declare matters and can be cross-checked against ITR and GST data.
Revised MSME classification limits (effective 1 April 2025)
| Category | Investment up to | Turnover up to |
|---|---|---|
| Micro | Rs 2.5 crore | Rs 10 crore |
| Small | Rs 25 crore | Rs 100 crore |
| Medium | Rs 125 crore | Rs 500 crore |
Note: An enterprise moves up a category the moment it crosses the ceiling on either investment or turnover. Any fees mentioned by third parties are indicative only and the government charges nothing for Udyam registration itself.
Common mistakes to avoid
- Paying a fee for registration. The official process is free. Anyone charging a government fee is misleading you; only optional professional assistance has a cost.
- Skipping the annual update. Every registered MSME must update turnover, investment and ownership details on the portal each year, or the status can be marked inactive.
- Mismatched PAN and GST data. If declared figures do not reconcile with ITR and GST records, classification can be challenged.
- Assuming traders are excluded. Retail and wholesale traders have been eligible since July 2021.
Consequences of non-compliance
Failure to complete the annual information update on the Udyam portal can render the registration inactive, which suspends access to MSME benefits until the update is filed. Companies that owe a registered Micro or Small supplier for more than 45 days must report it in MSME Form I to the Ministry of Corporate Affairs, a half-yearly return due by 31 October (April to September) and 30 April (October to March).
Under Section 43B(h) of the Income Tax Act, 1961, a buyer who delays payment beyond the MSMED Act timeline loses the expense deduction for that financial year, increasing taxable profit until the dues are cleared.
How these provisions interact
Section 43B(h) of the Income Tax Act borrows its 15-day and 45-day payment timelines directly from Section 15 of the MSMED Act, 2006, so the income tax consequence only bites where the supplier is a registered Micro or Small enterprise under Udyam. MSME Form I under the Companies Act runs in parallel, requiring corporate buyers to disclose the same overdue amounts to the Ministry of Corporate Affairs.
Old vs revised classification limits
| Category | Old turnover limit | Revised turnover limit |
|---|---|---|
| Micro | Rs 5 crore | Rs 10 crore |
| Small | Rs 50 crore | Rs 100 crore |
| Medium | Rs 250 crore | Rs 500 crore |
Key takeaways
- Udyam registration is free, online and grants a permanent 12-digit URN under the MSMED Act, 2006.
- Revised limits from 1 April 2025 mean Micro now reaches Rs 10 crore turnover and Rs 2.5 crore investment.
- Classification is composite, using both investment and turnover, and is recalculated yearly.
- Section 43B(h) makes registering as a supplier commercially significant, as it affects when buyers can claim deductions.
Frequently asked questions
How long does Udyam registration take?
It is usually instant. Once Aadhaar, PAN and GST details validate, the certificate is generated and emailed within minutes.
Is a separate registration needed for each business location?
No. One Udyam registration covers the enterprise, and additional units or branches are added within the same registration.
Can I register without GST?
Yes, if your business is legally exempt from GST. Where GST is mandatory for your turnover or activity, the GSTIN is required.
Does Udyam registration expire?
No. The URN has lifetime validity, but you must complete the annual information update on the portal to keep the status active.
What happened to Udyog Aadhaar registrations?
Udyog Aadhaar was replaced by Udyam in July 2020. Older registrations needed to migrate to the Udyam portal to remain valid.
Do existing MSMEs need to re-register after the 2025 revision?
No. The revised limits apply automatically, and existing registrations benefit without any re-registration.
