When employees apply for housing provident fund withdrawal business, they first need to fill in the declaration information in the "Commitment Letter on Housing Provident Fund Withdrawal" and make a commitment. After that, anyone who can obtain information through relevant departments for online audit will no longer be required to provide relevant certification materials, and it will be more convenient for units and employees to withdraw housing provident fund. For the business of withdrawing provident fund from retired employees, the process is also simplified. If the employee reaches the legal retirement age and the unit has sealed the employee's housing provident fund account, then the employee can handle the provident fund withdrawal business without submitting any materials. The biggest degree of "slimming" is Beijing. In the future, employees who have paid the state-controlled provident fund can purchase second-hand houses in Beijing, and they only need to pass identity verification to handle business, without submitting other materials. It is understood that this part of the business can account for 60% of the total extraction.
