Registrations to look at
- Udyam (MSME) registration. Not compulsory, but most scheme and bank loans (MUDRA, CGTMSE, PMEGP) ask for it.
- GST registration. Compulsory once turnover crosses ₹40 lakh a year for goods, or ₹20 lakh for services. Compulsory from the first sale for supplying goods to another state, whatever the turnover.
