Udyam Registration Benefits: MSME 45-Day Rule, Interest, ODR Portal

The biggest Udyam registration benefits are legal protection against late payment and easier access to credit and government purchases. A buyer must pay a Udyam-registered micro or small manufacturer or service provider within the agreed period, which cannot exceed 45 days from acceptance (MSMED Act, s.15), or pay compound interest at three times the RBI bank rate (s.16). Registration is free at udyamregistration.gov.in, and unpaid bills are now claimed on the MSME ODR portal (odr.msme.gov.in).

What Udyam registration is, and who should do it

Udyam registration is the government’s recognition that your business is a micro, small or medium enterprise under the Micro, Small and Medium Enterprises Development Act, 2006. The classification limits were raised by Notification S.O. 1364(E) of 21 March 2025, and the Ministry of MSME has clarified that the higher limits apply from 1 April 2025 for all purposes.

The process is free. You need the Aadhaar of the proprietor, managing partner or director, and the PAN of the business; GSTIN is needed where GST registration is compulsory.

Udyam registration benefits: the list that matters

• Protection against delayed payment for micro and small manufacturers and service providers (ss.15 to 24 of the MSMED Act).
• Priority sector lending: banks count loans to MSMEs towards their priority sector targets, which helps small units get credit.
• Collateral-free credit through the Credit Guarantee Fund Trust for Micro and Small Enterprises (CGTMSE), offered by lending banks.
• Government purchases: under the Public Procurement Policy for Micro and Small Enterprises, central ministries and public sector undertakings aim to buy at least 25% of their annual purchases from MSEs, and registered MSEs often get tender fee and earnest money relief.

Retail and wholesale traders can register on Udyam since the Ministry’s office memorandum of 2 July 2021, but only for priority sector lending. Traders cannot use the delayed payment mechanism.

The MSME delayed payment 45 days rule explained

Section 15 of the MSMED Act says the buyer must pay on or before the date agreed in writing, and that date cannot be more than 45 days from the day the buyer accepted (or is deemed to have accepted) the goods or services. If there is no written agreement on the date, payment is due within 15 days of acceptance. Deemed acceptance applies if the buyer raises no written objection within the agreed period, or within 15 days of delivery where none is agreed.

So a purchase order that says “payment in 90 days” does not override the law. Under s.16, if the buyer pays late, he owes compound interest with monthly rests at three times the bank rate notified by the Reserve Bank of India, from the due date, “notwithstanding anything contained in any agreement”. Under s.23, the buyer cannot claim that interest as a deductible expense for income tax.

The tax push. Section 43B(h) of the Income-tax Act, 1961, effective from assessment year 2024-25, allows a buyer to deduct amounts owed to a micro or small enterprise only in the year they are actually paid if the payment crosses the s.15 time limit. The Income-tax Act, 2025, in force from 1 April 2026, carries the same rule in section 37(2)(g), as the Government told the Rajya Sabha on 21 July 2026.

MSME Samadhan complaint: now filed on the ODR portal

MSME Samadhaan (samadhaan.msme.gov.in) was the Ministry’s portal for delayed payment cases. The Ministry launched the MSME ODR portal in 2025, and from 15 October 2025 all new delayed payment references must be filed on odr.msme.gov.in. Samadhaan now redirects new filers and serves only to migrate old cases.

1. Send a demand notice citing ss.15 and 16, with principal and interest worked out. See legal notice for recovery of money.
2. File on the ODR portal with your Udyam number, buyer details, invoices, purchase orders, delivery proof and correspondence.
3. Negotiation and conciliation. The Micro and Small Enterprises Facilitation Council (MSEFC) of your state takes up the case and first tries conciliation (s.18).
4. Arbitration. If conciliation fails, the Council arbitrates or refers the case to an institution. The reference should be decided within 90 days (s.18(5)).
5. Challenge needs a deposit. A buyer who wants to challenge the award in court must first deposit 75% of the amount (s.19).

Register before you sign. In Silpi Industries v. Kerala SRTC (2021) the Supreme Court held that the supplier must be registered when the contract is made. In NBCC (India) Ltd. v. State of West Bengal (2025) a two-judge bench doubted this and referred the question to a larger bench, so it is unsettled. Register first, and print your Udyam number on every invoice.

Real-life example

Kavita runs a micro unit in Kanpur making packaging boxes. A Noida distributor holds ₹6 lakh of her bills for four months, citing “120-day credit”. Registered on Udyam before the order, she sends a notice under ss.15 and 16 and files on the ODR portal. At conciliation the distributor pays principal and interest: an award would need a 75% deposit to challenge, and the delay also costs it a tax deduction.

Frequently asked questions

What are the Udyam registration benefits for a small business?

The main ones are the MSMED Act’s 45-day payment rule with compound interest at three times the RBI bank rate, priority sector lending, collateral-free credit through CGTMSE, and preference in government purchases. Registration is free on udyamregistration.gov.in.

Is MSME registration the same as Udyam registration?

Yes. Since 1 July 2020, MSME registration is done only as Udyam registration on the government portal.

No. Retail and wholesale traders on Udyam get priority sector lending benefits only, and Facilitation Councils do not entertain their payment claims. The rule protects micro and small manufacturers and service providers.

New delayed payment cases go on the MSME ODR portal, odr.msme.gov.in, from 15 October 2025. The old Samadhaan portal redirects new applicants there.
