Dear Saswata ji,
It seems there is a problem with the quoted statements. Quoted statements are deleted from my above post and therefore, the post is sounding improper.
I raised the issue in regards to your following two statements in 'quotes'.
1. Exemption from PF act can only happen via filing of form 11
2. If you are above the limit, you can make voluntary contribution, but the employer is not required to give matching contribution.
I raised the issue since up till now, my understandings on Form 11, excluded employees, contribution beyond statutory limit, voluntary contribution etc. are different My understandings on this subjects are discussed by me in various posts on mine in this forum. I always delivered my same understandings to various platforms including in my lectures and seminars which seems to be wrong now. Therefore, I want to conform your quotes with supporting proof.
