Eligibility, classification, documents, Udyam Aadhaar process, benefits, and the new 45-day MSME payment rule that changes everything.
Udyam registration is the cheapest, fastest, highest-ROI government registration available to Indian businesses. It's free, fully online, takes 30 minutes — and unlocks collateral-free loans, the 45-day MSME payment rule, lower-interest credit, and dozens of state-level subsidies. Yet two out of three eligible businesses don't have it. This guide walks you through every step. Prefer it done for you? Our MSME registration service issues the Udyam certificate the same day.
MSME (Micro, Small and Medium Enterprise) classification was overhauled in 2020 — and refined again in 2025 — to use a composite criterion: investment in plant & machinery PLUS annual turnover. Service and manufacturing enterprises are now treated identically.
| Category | Investment | Turnover |
|---|---|---|
| Micro | ≤ ₹1 Cr | ≤ ₹5 Cr |
| Small | ≤ ₹10 Cr | ≤ ₹50 Cr |
| Medium | ≤ ₹50 Cr | ≤ ₹250 Cr |
From April 2025, the limits were revised upward in some categories. The composite rule still applies — if either investment OR turnover exceeds the cap, the enterprise moves to the next category automatically.
Udyam is intentionally paperwork-light. You don't upload anything — the system pulls data directly from PAN, GST and ITR databases.
Under Section 15 of the MSMED Act, any buyer who procures goods or services from a registered MSE must pay within the time agreed in the contract — and in any case within 45 days. Default triggers compound interest at 3× the RBI bank rate (currently ~24% effective).
From FY 2023–24, Section 43B(h) of the Income Tax Act denies expense deduction to the buyer until the MSE payment is actually made. This means delayed payment now hits the buyer's tax bill as well as exposing them to interest. We've written a dedicated piece on this — link below.
Udyam is the single highest-leverage half-hour any Indian business owner will ever spend with a government portal. Free, paperless, lifetime — and it unlocks legal protection, cheaper credit and a fairer payment cycle. If your business isn't registered yet, do it this week.

The MSME 45 days payment rule explained: when the 15/45-day clock starts, 24% compound interest under the MSMED Act, the Section 43B(h) tax disallowance for buyers, MSME Form 1 reporting, and what suppliers must do to claim protection.
