It is not your fault, but your employer's decision. There may be a query from the background verification team because nowadays they examine every detail of service like a crime investigation team. Not having PF or delayed enrollment in PF is not a crime, and if a mistake has occurred, it would never be attributed to the employee.
Understanding PF Enrollment Issues
Now, regarding the query, let's consider this scenario: You joined your first company in December 2020. At the time of your joining, your salary was above Rs 15,000, so you were not given PF. According to the law, an employee who joins a company for the first time with a salary above Rs 15,000 can be excluded from PF. However, in 2023, the company decided that PF is a good investment, and everyone in the company should have PF. Therefore, they decided to enroll you under EPF from December 2023. The problem is solved.
But you can ask the Personnel Manager (HR Manager) why this happened.
