Gratuity Eligibility and Considerations
First of all, for gratuity, 5 years of continuous service is required. If you have taken any policy (like LIC) for gratuity and you have registered that employee in June 2013, then for gratuity calculation, you have to consider June 2013 as the joining date. If you haven't taken any policy for gratuity and are managing the gratuity part at your company level, and on paper, you have a record that the concerned employee actually joined in 2000, and your management has approved this, then you can provide him/her with gratuity benefits from 2000.
Difference Between PF and Gratuity Registrations
PF and gratuity registrations are different as PF requires a minimum of 20 employees, while gratuity requires 10 employees. Therefore, there is no direct relation between gratuity and PF. Finally, if the management knows the actual date of joining of that employee and genuinely wants to provide him/her with benefits, then it can pay that amount as an incentive.
I hope this information is helpful to you.
