If you work overseas, it is not mandatory for you and your employer to pay CPF contributions.

However, you may wish to build up your retirement savings by making voluntary CPF contributions, up to the approved limit. However, if your employer in Singapore is paying CPF contributions for you, the employer's contributions will count towards the limit.

Options available to you:

Contribute to all three accounts Contribute to Medisave account only

You can make a one-time payment, or regular contributions deducted by GIRO to your CPF account. Do note that voluntary contributions do not qualify for tax deduction.

You may wish to refer to the IRAS website for more information on the prevailing tax rules.
