Understanding Interns and Their Exclusion from PF and ESI
An intern is a student undergoing a program at a university, engaging in project work or an internship as part of the university curriculum. The duration of such internships may extend to four or six months, after which they return to their campus. These interns are completely excluded from PF (and ESI). To support this exclusion, you only need to produce a letter from their institution requesting permission for them to undertake the project or internship. The letter should clearly state that they are doing it as part of the curriculum.
If you pay them Rs 21,500 per month, no document is required to exclude them from ESI. However, you can collect Form 11 (PF), which declares that they do not have any PF account.
Clarification on Intern vs. Trainee
Paying this amount to an intern may imply that you should be paying a regular employee around Rs 50,000 as a starting salary. Or is it that you mean a TRAINEE when you refer to an intern? In that case, the status will change, and the intern will qualify for various rights under different labor enactments such as Gratuity, annual leave, etc.
