The CPF (Amendment) Bill introduces a pilot "Contribute-as-you-Earn" scheme to help self-employed persons make regular MediSave contributions, with the government considering matching contributions for participants. The bill also amends the CPF Act to allow refunds for CPF contributions on repayable conditional wages, such as sign-on bonuses. Additionally, the Retirement Sum Scheme payout duration is shortened from age 95 to 90 to increase monthly payouts, with no reduction for existing recipients.
