Dear Saurav, you are right, if any employee who has withdrawn his previous PF accumulation and do not want to be a pf member in new employment, has to fill this declaration form. In another case any new employee has right to be excluded from such membership if his first wage/salary (Basic+DA) is more than 6500 /-pm and has withdrawn his previous PF accumulation or he never been a member of Any PF scheme previously.If we exclude any member from PF deductions,this declaration in form 11 is very necessary for forthcoming inspection by PF department,
Regarding Pension Scheme Certificate, it is issued by PF Department after eligibility of the member for pension. if he left the job (After 10 years of regular service) and enters in a new employment. This certificate should be submitted to new employer so that his seniority and other benefits of PF pension can be continued in new job also.
