Dear Minal,
According to The Payment of Gratuity Act 1972, every organization must pay gratuity amount to employees who have completed 5 years of service with 240 days in each year. This amount will be paid at the time of superannuation or resignation of an employee.
The above-mentioned condition is not applicable in death cases. In death cases, 5 years of service is not mandatory.
Recently, the Government of India has increased the existing ceiling from 3,50,000 to 10,00,000. The gratuity calculation is: Wage last drawn (Basic+DA)/26*15*No. of years of service.
Venki
