Dear Vinoth, for the purpose of calculation of Total Service under the Payment of Gratuity Act, 1972, you have to consider Service from the Date of Joining till the date of Leaving From India, New Delhi
Why would the DOJ and PF deduction date differ?
Both should be same, unless you are exempted till such time while having less staff.
If the registration is done late you need to pay contribution from the DOJ. From India, Hyderabad
