The 45-day payment rule
This is the most valuable and least-used benefit. Under the MSMED Act, a buyer must pay a registered micro or small enterprise within 45 days of accepting goods or services. Delay beyond that attracts compound interest at three times the RBI bank rate.
The enforcement mechanism is the MSME Samadhaan portal, where you can file a delayed payment complaint directly. What actually moves large buyers is a quieter provision: a buyer who has not paid within the deadline cannot claim that expense as a deduction in their own income tax return. Finance teams at large companies understand this immediately.
To use it, you need to be registered before the transaction, and it is worth stating your Udyam number on your invoices.
Collateral-free lending
The Credit Guarantee Fund Trust for Micro and Small Enterprises guarantees bank lending to MSEs without security. For a business with no property to pledge, this is frequently the difference between getting working capital and not.
To claim it, approach a member lending institution — most public sector banks and many private ones — and specifically ask for the facility to be covered under CGTMSE. Branch staff do not always volunteer it.
Tender advantages
Registered MSEs get exemption from earnest money deposit on government tenders, and a defined share of central government procurement is reserved for them under the Public Procurement Policy, with a sub-quota for enterprises owned by SC/ST and women entrepreneurs.
- Link your Udyam number to your GeM seller profile, or the exemption does not apply
- Link it on NSIC registration too, if you hold one
- Quote the Udyam number in the tender document where a bidder classification is asked for
Subsidies worth knowing about
Several schemes reimburse costs that MSMEs incur anyway. These change from time to time and vary by state, so check the current position before relying on any of them.
- Reimbursement of a portion of ISO certification costs
- Subsidy on patent and trademark registration fees
- Interest subvention on bank loans under various central schemes
- Electricity tariff concessions in several states
- Preference and price relaxation in state government procurement
The revised classification limits
The 2025 revision widened the MSME definition considerably, bringing a lot of growing businesses back into the net.
| Category | Investment up to | Turnover up to |
|---|---|---|
| Micro | ₹2.5 crore | ₹10 crore |
| Small | ₹25 crore | ₹100 crore |
| Medium | ₹125 crore | ₹500 crore |
If you still hold Udyog Aadhaar
Udyog Aadhaar is no longer valid and has been fully replaced by Udyam. If you have not migrated, your registration is not recognised for any of the benefits above — which means businesses holding an old Udyog Aadhaar number are, in practice, unregistered.
Migration is straightforward and free. It is worth checking, because a surprising number of businesses assume they are covered when they are not.
