How to Apply for a CPF CSN Company Account

If you are a new start up and hiring Singaporeans or PR in Singapore, you will need a company account from CPF called CPF CSN in order to process your monthly CPF submissions. Here’s a short 5-minute guide on how you can apply for a CPF CSN

A brief introduction to CPF

Central Provident Fund (CPF) is an essential social security system for Singapore Citizens and Permanent Residents to save up funds for retirement. Employees and employers contribute a certain amount to the employees’ CPF account based on the employee’s monthly salary. And it is not just monthly salary that attracts CPF contribution. Payments by companies such as bonuses, AWS, transport allowance, commissions and even Chinese New Year Ang Pow monies will attract CPF payment as well.

These funds will then be channelled into the following three sub accounts.

  1. Ordinary Account: Mainly reserved for education and housing needs.
  2. Special Account: Mainly reserved for retirement needs.
  3. Medisave Account: Mainly reserved for healthcare needs.

Only Singaporeans or Permanent Residents are eligible for a CPF account and contribution is compulsory and mandated by the law.

It is the companies’ responsibility to inform the CPF board of how much contribution is required for each employee on a monthly basis – this is known as the monthly CPF submission. And in order for companies to do a CPF submission, they will need a CSN number.

What is CSN?

A CSN is short for CPF Submission Number and is issued by CPF Board for every company that contributes to employees’ CPF account.

Pro Tip: Generally companies use their CSN to liaise with CPF board for CPF matters. However, some other government ministry may also require the use of a company’s CSN number. For example, Ministry of Manpower (MOM) requires company to have a CSN number before they are allowed to hire foreigners.

A CSN is made up of a company’s Unique Entity Number (UEN) issued by ACRA or an individual’s NRIC/FIN (if an individual is trading under their own name) and a CPF Payment Code.

The CPF Payment Code allows CPF to identify the types of payment employers make to the CPF Board. This includes CPF Contribution, Voluntary Contributions and Medisave Contributions etc. Different types of payment will require a different CSN number. Ie a company may have multiple CSN number.


How to Apply for a CSN?

There are only two types of entities that can apply for a CSN.

  • UEN registered entity
  • Sole Proprietor
