How do I check which platform workers have opted in for increased CPF contributions?
Platform workers born before 1995 may opt in to increased CPF contributions via the platform worker opt-in form. They may do so at any time, as there is no deadline to do so. Opt-in is irreversible. 
 
As CPF contribution rates depend on platform workers’ opt-in status, you will need to validate your platform workers’ latest opt-in status before calculating their CPF contributions. 
 
The monthly query with CPF Board via Secured File Transfer Protocol (SFTP) will inform you of the latest opt-in status of your platform workers. There is no need to include platform workers born in or after 1995 in the query, as it is mandatory for them to make the increased CPF contributions. You may refer to this step-by-step guide to conduct monthly query on your platform worker's opt-in status.
 
CPF Board will inform you of the opt-in status of your platform workers on the 20th of each month, via the monthly query. You can refer to the illustration below for the opt-in status query timeline.
