For medical treatment of immediate dependants (spouse, children, mother or father) advance is allowed. For this no minimum service is required. But advance is allowed only if hospitalisation is required at least for one month. For this a certificate from medical practitioner is required to be submitted. Similarly, a declaration from the employer that the dependant of the employee who is to go for treatment is not covered by ESI is also required to be submitted. The amount of advance will be six time the salary (which is qualified as salary for deduction of PF) or full of employee's own share in the EPF account whichever is less. For details please contact the Enforcement Officer or PRO of the EPFO.
