Udyam
What Udyam means, how it works, a worked example, the mistakes we see and the questions founders ask.
DefinitionUdyam registration is the free, instant online registration of a micro, small or medium enterprise with the Ministry of MSME, based on investment and turnover, giving a Udyam number and certificate.
Any proprietorship, firm, LLP or company can register on the Udyam portal with Aadhaar and PAN in about ten minutes, at no cost. The portal classifies you as micro (investment up to ₹2.5 crore and turnover up to ₹10 crore), small or medium using data pulled from ITR and GST returns, and issues a certificate that updates automatically. You meet it when a customer or bank asks for your MSME certificate, when claiming the ₹4,500 trademark fee, when applying for CGTMSE or Mudra loans, and when filing government tenders that reserve quotas for MSMEs. What it means for you: registered micro and small suppliers must be paid within 45 days by law, buyers must report delays in MSME-1, and unpaid amounts cannot be deducted by the buyer under Section 43B(h), which gives your invoices real teeth.
How Udyam works
Udyam registration under the MSMED Act 2006 is done on the Udyam portal with the proprietor's, partner's or director's Aadhaar and the enterprise's PAN, and the GSTIN where one exists. The portal pulls investment in plant and machinery or equipment and turnover from the income tax and GST systems and classifies the enterprise using the limits in force since 1 April 2025: micro up to ₹2.5 crore of investment and ₹10 crore of turnover, small up to ₹25 crore and ₹100 crore, medium up to ₹125 crore and ₹500 crore. The higher of the two measures decides the category, export turnover is excluded, and the certificate updates automatically as returns are filed.
The Udyam number (UDYAM-XX-00-0000000) and certificate are issued at once, free of charge, and have no expiry. An informal micro business without a PAN or GSTIN can register through the Udyam Assist Platform with its bank's help. One registration covers all units and activities of the enterprise, and manufacturing and services are treated alike.
Registration unlocks the protections of Sections 15 to 24 of the MSMED Act for micro and small enterprises: a buyer must pay within the agreed period, capped at 45 days (15 days with no written agreement), or pay interest at three times the bank rate compounded monthly, claimable through the MSME Samadhaan portal and the Facilitation Council. Since 2023-24, Section 43B(h) of the Income-tax Act disallows a buyer's deduction for amounts owed to micro and small suppliers beyond that period until paid, and companies must report overdue MSME dues half-yearly in MSME-1. Other benefits include priority sector lending, CGTMSE guarantee cover, 25% of central purchases reserved for micro and small enterprises, access to TReDS invoice discounting, and the lower ₹4,500 trademark fee.
A Nashik packaging unit registers on the Udyam portal in April 2026 as a small enterprise with ₹3 crore of machinery and ₹18 crore of turnover. In September a listed buyer leaves a ₹14 lakh invoice unpaid for 70 days; the unit cites its Udyam number and Section 43B(h), the buyer's auditor flags the disallowance, and the invoice is paid with a note that future terms are 45 days. The same certificate secures a CGTMSE-backed ₹80 lakh limit without collateral.
Mistakes we see with Udyam
- Registering with the proprietor's details but leaving out the GSTIN, so turnover is not pulled and the classification stays wrong.
- Paying an agent for registration that is free on the government portal, often on a look-alike website.
- Assuming medium enterprises get the 45-day payment protection; it applies to micro and small suppliers only.
- Not quoting the Udyam number on invoices, which makes it harder for the buyer's auditor to apply Section 43B(h) in your favour.

Questions founders ask about Udyam
Is Udyam registration mandatory?
No, but without it a business cannot claim MSME benefits: the 45-day payment protection, Samadhaan, CGTMSE cover, priority sector lending, procurement preferences and the reduced trademark fee. It is free and takes minutes, so there is little reason not to register.
Can a startup or a private limited company register under Udyam?
Yes. Any proprietorship, partnership, LLP, company, trust or society engaged in manufacturing or services can register. Traders, including wholesale and retail, have been eligible since July 2021 for priority sector lending purposes, though some scheme benefits remain limited to manufacturing and services.
What does Section 43B(h) mean for a buyer?
A buyer that pays a micro or small supplier after the MSMED Act period (45 days with a written agreement, 15 days without) cannot deduct the expense in the year it is incurred; it is allowed only in the year of actual payment. The supplier's Udyam status at the time of supply decides whether the rule applies.
