Thanks to Surya-Mukherjee for the correct answer. I am following the same rule that even if the salary is increased in between the contribution period and even if it is more than 10,000/-, i.e., 12,000/- till September of the contribution, we must recover ESI contribution on 12,000/-
However, in the posts by Richrachna on 3/8/07 and hrshah on 14/8/07, it is mentioned that the maximum limit for ESI recovery is 10,000/- and the contribution on 10,000/- is Rs. 175/-, which is a little confusing. Any other senior member may give their view on this, please.
I am a new member, and I am very thankful for the senior members for their valuable insights on many subjects.
